South Dakota Feasibility Study Consultant: Lender-Grade SBA and USDA Feasibility Studies Calibrated to South Dakota

MMCG Invest, LLC is a feasibility study consultant that produces feasibility studies for South Dakota projects where the analytical questions turn on five variables that no other Upper Midwest balance sheet replicates: the only state tax code in the nation that pairs a zero personal income tax and a zero corporate income tax with a 2 percent contractor's excise tax on gross construction receipts (SDCL Chapter 10-46A, in force since 1984) stacked on top of the 4.2 percent sales and use tax that contractors owe on materials, a dual construction levy that adds roughly three points to hard cost on every ground-up project and that MMCG carries into the cost budget at the statutory 2.041 percent bid factor, with the state sales rate scheduled to revert from 4.2 percent to 4.5 percent on July 1, 2027 under the sunset written into 2023's HB 1137 and redirected into homeowner relief by SB 245, signed March 12, 2026; a three-class property tax regime in which SB 216 (signed March 13, 2025) caps countywide owner-occupied assessment growth at 3 percent for five years while leaving commercial and agricultural property entirely outside the cap, and in which the 2026 session rejected (HB 1253, failed in the Senate 9 to 24 on March 9, 2026) the only proposal that would have extended a 5 percent cap to commercial parcels; the Sioux Falls financial services complex seeded by the 1980 usury repeal and Citibank's February 19, 1981 charter, which now administers a little more than $906 billion in trust assets across 114 chartered trust companies (South Dakota Division of Banking, year-end 2025) and anchors a professional-employment and office demand base without peer in any metro of comparable size; an agricultural processing capital cycle led by Smithfield's $1.29 billion Sioux Falls plant (the largest private capital investment in state history), the $500 million High Plains Processing soybean plant that opened in Mitchell on September 9, 2025, Bel Brands' $200 million Brookings expansion that broke ground March 11, 2026, and a dairy herd that reached 215,000 cows on January 1, 2025 (up 117 percent in ten years, the fastest growth of any state), operating alongside a 16-plant, 1.5 billion gallon ethanol industry whose carbon-intensity economics were reset by HB 1052's March 6, 2025 ban on eminent domain for carbon dioxide pipelines; and an electricity profile in which wind delivered 59 percent of in-state generation in 2024 (second only to Iowa) and the four Missouri River mainstem dams another 21 percent, yet a Legislature that in 2025 declined a hyperscale data center sales tax exemption (HB 1005) and in March 2026 enacted siting restrictions on large data centers instead, placing South Dakota in the opposite policy posture from Iowa, Nebraska, and North Dakota on the single largest source of new industrial load in the region.

South Dakota closed the latest Census estimate at approximately 925,000 residents across 66 counties, with Sioux Falls and Rapid City absorbing the large majority of net in-migration and the balance of the state organized around the James River agricultural valley, the Missouri River reservoir system, and the Black Hills. The state hosts a single SBA South Dakota District Office in Sioux Falls at 200 North Phillips Avenue, Suite L101, serving all 66 counties, and a single USDA Rural Development State Office in Huron at 200 4th Street SW, Federal Building, Room 210, administering Business and Industry Guaranteed Loans, REAP, Community Facilities, and Water and Environmental Programs through seven area offices in Aberdeen, Watertown, Mitchell, Pierre, Sioux Falls, Rapid City, and Yankton. The Governor's Office of Economic Development administers the state incentive stack (the REDI Fund, the Reinvestment Payment Program, the South Dakota Jobs Program, and the Local Infrastructure Improvement Program) and South Dakota Housing administers the Housing Infrastructure Financing Program and the state's Low-Income Housing Tax Credit allocation.

Five South Dakota-specific variables redefine every South Dakota deal and require the state-specific calibration that a feasibility study consultant working from a national template does not deliver. South Dakota is the trust-capital, wind-energy, and protein-and-biofuel anchor of the northern Plains, and it sits inside a tax code that no neighboring state reproduces in full.

First, the no-income-tax stack and the dual construction tax. South Dakota levies no personal income tax and no corporate income tax; banks, savings institutions, trust companies, and credit card banks instead pay a graduated bank franchise tax under SDCL Chapter 10-43 that begins at 6 percent of net income and steps down in brackets above $400 million. What the state does levy, and what every out-of-state lender misprices, is the contractor's excise tax under SDCL Chapter 10-46A: 2 percent of the gross receipts of every prime contractor on realty improvement and construction, in force since May 1, 1984, and applied on top of the 4.2 percent state sales and use tax that contractors pay on materials incorporated into the project. No other state stacks a gross-receipts construction tax on a materials sales tax in this way. The Department of Revenue publishes a 2.041 percent bid factor so that the excise tax can be recovered inside the contract price, and municipalities may layer up to 2 percent of municipal sales tax and a 1 percent municipal gross receipts tax on lodging, prepared food, alcohol, and admissions on top of the state rate. The state rate itself was cut from 4.5 percent to 4.2 percent on July 1, 2023 under HB 1137 with a statutory sunset; repeated efforts to make the cut permanent failed in 2024 and 2026, and SB 245, signed by Governor Larry Rhoden on March 12, 2026, directs the roughly $114 million of annual revenue from the July 1, 2027 reversion into the Homeowner Property Tax Reduction Fund. For any South Dakota project with construction scheduled to run past July 1, 2027, MMCG models the materials sales tax at 4.5 percent on the post-reversion portion of the draw schedule, carries the 2 percent excise on the full contract, and separately models the 1 percent municipal gross receipts tax on stabilized hotel, restaurant, and entertainment revenue. On a hotel, a car wash, or a gas station, that combination is the highest-leverage cost and revenue variable a South Dakota study contains.

Second, the three-class property tax regime and the residential-only assessment cap. South Dakota classifies real property as agricultural (valued on productivity rather than market), owner-occupied single-family, and "other" non-agricultural, the last of which includes every commercial, industrial, and non-owner-occupied residential parcel. County, municipal, and township levies apply uniformly across classes; the school general-fund levy does not, and commercial property carries the highest school levy per $1,000 of value, roughly double the owner-occupied levy. SB 216, signed March 13, 2025, capped the countywide growth in owner-occupied assessed value at 3 percent per year for five tax years, capped the new-construction-driven growth in taxing-district budgets at 3 percent, and raised the assessment-freeze income limits to $55,000 for single filers and $65,000 for multi-member households on homes valued up to $500,000. None of it applies to commercial or agricultural property. The 2026 session tested the question directly: HB 1253, which would have capped annual assessment growth on both owner-occupied and commercial property at 5 percent with a five-year market reset, failed in the Senate 9 to 24 on March 9, 2026, and SB 96 authorized counties to levy up to a half-percent county sales tax whose proceeds must first go to owner-occupied relief before any remainder reaches agricultural and commercial parcels. The underwriting consequence is that income property in South Dakota gets no assessment-cap protection while the residential base around it does, which shifts levy pressure toward the commercial class over the projection horizon. MMCG models the property tax line from the current county levy sheet in Minnehaha, Lincoln, Pennington, Brown, Codington, or the relevant county, with the commercial school levy applied explicitly, rather than from a statewide effective-rate average.

Third, the Sioux Falls trust and credit card capital complex. In January 1980 South Dakota repealed its usury ceiling; on February 19, 1981 Citibank chartered Citibank (South Dakota), N.A. and moved its credit card operation to Sioux Falls, and by 1983 forty-four states had loosened their own usury laws in response. Citi's Sioux Falls operation today runs approximately 1,300 employees in a 150,000 square foot campus on 19 acres, and Wells Fargo, First PREMIER Bank and PREMIER Bankcard, and a deep bench of card-issuing and servicing operations followed. The second layer is the trust industry. A standing governor's task force has revised the trust code nearly every session since the 1990s, and the Division of Banking reported that total assets under administration by South Dakota-chartered trust companies stood a little north of $906 billion at the end of 2025, up $91 billion (11 percent) in a single year even as one large digital-asset custodian converted to a national charter and left the state system; the charter count stood at 114 (69 public, 45 private) at year-end 2025 after $815 billion at year-end 2024. South Dakota Trust Company alone administers more than $165 billion for clients from 54 countries and 47 states. For a Sioux Falls office, mixed-use, or hospitality study, this is a structural professional-employment floor that a Census income table does not capture; for any South Dakota deal involving a bank or trust-company sponsor, the bank franchise tax replaces the corporate income tax in the sponsor return model and must be modeled to the entity's actual net income bracket.

Fourth, the agricultural processing capital cycle and the carbon-pipeline reset. South Dakota ranks seventh in the nation in all cattle and calves at 3.55 million head, ninth in hogs at 2.24 million, sixth in corn for grain at 884 million bushels, ninth in soybeans at 231 million bushels, second in sunflowers at 40.7 percent of national output, and first in bison, on 42.3 million acres of land in farms (USDA NASS, May 2025 release). The processing layer built on that base is in the most active capital cycle in the state's history. Smithfield Foods, whose existing Sioux Falls plant processes more than 20,000 hogs per day and supports more than 3,100 jobs, secured a Reinvestment Payment of up to $29,975,400 for a new $1.29 billion packaged-meats and fresh-pork plant at Foundation Park, the largest private capital investment in South Dakota history, with an $89.9 million tax increment district advanced by the city in March 2026, groundbreaking expected in the first half of 2027, and operations by late 2028. High Plains Processing opened its $500 million, 35 million bushel per year soybean and multi-seed crush plant in Mitchell on September 9, 2025, managed by South Dakota Soybean Processors in a joint venture with BP Products North America; AGP's roughly $300 million Aberdeen plant, opened in 2019, crushes 50 to 60 million bushels per year. The dairy corridor along Interstate 29 has more than doubled the state herd to 215,000 cows as of January 1, 2025, the fastest growth in the country, and is approaching 240,000 head, supported by Agropur's Lake Norden plant (expanded to 9.3 million pounds of milk per day and slated for a further $60 million modernization announced in February 2026), Valley Queen Cheese in Milbank, and Bel Brands' $200 million Brookings expansion that will double the only Babybel plant in the United States by 2028. The ethanol layer runs 16 plants and roughly 1.5 billion gallons of annual capacity, the fifth-largest state output in the nation at 8 percent of the U.S. total, anchored by POET (headquartered in Sioux Falls, founded in Scotland, South Dakota in 1987, and the largest biofuel producer in the world at roughly 3 billion gallons per year across more than 30 plants) and by Glacial Lakes Energy in Watertown. Against that backdrop, HB 1052, a one-sentence bill signed by Governor Rhoden on March 6, 2025 and effective July 1, 2025, prohibits the use of eminent domain for carbon dioxide pipelines after Summit Carbon Solutions had secured roughly half of the voluntary easements it needed and had its first Public Utilities Commission application rejected in 2023. The practical effect for any South Dakota ethanol expansion, sustainable aviation fuel conversion, or co-product upgrade is that the plant's Section 45Z Clean Fuel Production Credit position must be modeled without an assumed sequestration pathway, and MMCG presents the with-and-without carbon-capture cases as a structured optionality analysis rather than assuming the more favorable carbon-intensity score.

Fifth, the renewable-energy profile and the data center policy inversion. Per the Energy Information Administration, wind provided 59 percent of South Dakota's electricity net generation in 2024, a larger share than in any state except Iowa, from approximately 3,450 megawatts of installed capacity across 25 wind farms (the largest, Deuel Harvest, at 300 megawatts); hydropower from the Oahe, Big Bend, Fort Randall, and Gavins Point dams on the Missouri River supplied another 21 percent; and renewables in total supplied 81 percent of in-state generation, second only to Vermont. Retail service is divided among Xcel Energy in the Sioux Falls region, NorthWestern Energy across the James River valley from Aberdeen through Huron and Mitchell to Yankton, Otter Tail Power in the Milbank and Sisseton corridor, Black Hills Energy in the Black Hills, and the East River Electric and Rushmore Electric cooperative families supplied by Basin Electric Power Cooperative. What South Dakota has not done is what its neighbors have done with that power. Iowa (Iowa Code Section 423.3(95)), Nebraska, and North Dakota all extend sales and use tax exemptions to qualifying data centers; South Dakota's largest data center draws 30 megawatts, the state has no hyperscale facility, HB 1005's proposed 50-year sales tax exemption for hyperscale data centers failed in committee in 2025, a 2026 bill (SB 232) proposed a one-year moratorium on new or expanded hyperscale facilities, and in March 2026 the Governor signed legislation imposing new siting restrictions on large data centers. A proposed 430 megawatt, $5 billion campus at Toronto in Deuel County, to be served by Otter Tail Power, remains the test case. For any energy-intensive South Dakota industrial study, MMCG models the utility's published commercial and large-load rate without any data-center exemption, and treats large-load interconnection and local siting approval as explicit entitlement risks rather than assumed.

South Dakota operates a single SBA District Office in Sioux Falls under District Director Bryson Patterson, covering all 66 counties. Fiscal year 2025 was the highest total dollar volume year for SBA lending in the state since 2022 and the highest dollar year ever for the 7(a) program in South Dakota, with more than $161 million guaranteed across the 7(a), 504, and microloan programs. First Bank & Trust of Brookings led 7(a) lending by count and dollars at 23 loans and $14 million supporting 332 jobs; Dakota Business Finance, the state's leading Certified Development Company, led 504 lending at 52 loans and $46 million supporting 847 jobs; and First Dakota National Bank of Yankton received the third-party 504 lender award at 14 loans and $21 million. The active South Dakota 7(a) and 504 lender stack also includes First PREMIER Bank, Dacotah Bank, BankWest, First Interstate Bank, Bell Bank, Plains Commerce Bank, Black Hills Federal Credit Union, and the national 7(a) platforms including Live Oak Bank. Certified Development Companies active in the state are Dakota Business Finance (Sioux Falls) and South Dakota Development Corporation (Sioux Falls); GROW South Dakota serves as the state microloan intermediary.

The USDA Rural Development South Dakota State Office in Huron is led by State Director Lorraine Polak, appointed in May 2025 after more than 25 years at South Dakota Housing, and operates through area offices in Aberdeen, Watertown, Mitchell, Pierre, Sioux Falls, Rapid City, and Yankton, which permits county-level engagement on Business and Industry, REAP, and Community Facilities applications. The REAP pipeline is among the most active in the northern Plains relative to state population: nearly $26.4 million across 106 projects since 2021, including an October 2024 round of $1.8 million across ten projects (with $1 million to Aberdeen Energy for its Mina ethanol expansion, alongside a $10.2 million electric infrastructure loan to Cam Wal Electric Cooperative) and a January 2025 round of $2.65 million across seventeen projects. Because nearly the entire state outside the Sioux Falls and Rapid City urbanized areas carries rural-eligible designation, USDA program fit is tested before SBA on every rural South Dakota deal above $3 million with a production-agriculture, food-processing, ethanol, or rural-infrastructure nexus.

The Governor's Office of Economic Development runs the REDI Fund (low-interest loans of up to 45 percent of project cost with a 10 percent minimum sponsor equity), the Reinvestment Payment Program (a rebate of up to the state sales and use tax paid on projects above $20 million or equipment above $2 million, the vehicle behind the Smithfield award and the CJ Schwan's $550 million, 600-job Sioux Falls plant that also drew a $30 million Future Fund grant), the South Dakota Jobs Program for projects below $20 million, the Local Infrastructure Improvement Program, and the Economic Development Partnership Program; the Board of Economic Development also approved a $7.5 million REDI loan to Elevate Rapid City for a 128-acre business park. South Dakota Housing administers the Housing Infrastructure Financing Program, capitalized at $200 million ($150 million state general fund plus $50 million ARPA, split $100 million loans and $100 million grants), which covers up to one-third of qualifying infrastructure cost at $25,000 per single-family lot and $10,000 per multifamily unit, with loans at 2 percent over ten years amortized up to 25; roughly 70 projects and an estimated 12,000 housing units had been funded by late 2024, and the Housing Board awarded a further $59.4 million on December 10, 2025. South Dakota Housing also allocates the state's Low-Income Housing Tax Credits and the Housing Opportunity Fund.

Tax increment financing under SDCL Chapter 11-9 runs a maximum 20-year term, requires that a district be at least 25 percent blighted by area or at least 50 percent by area dedicated to economic development, and sorts districts into Local, Industrial, Economic Development, and Affordable Housing classifications that determine their treatment in the state aid to education formula. The Department of Revenue counted 453 districts created since 1978 and 244 active at the close of the 2023 assessment year, and the $89.9 million Smithfield district is the largest recent example. South Dakota holds 25 designated Opportunity Zones, including tracts in Rapid City, Yankton, and Vermillion. Nine reservations occupy a material share of the state's land area, and any project on or adjacent to Indian Country carries fee-versus-trust title, Bureau of Indian Affairs leasehold, and tribal jurisdiction questions that determine collateral perfection and foreclosure remedies; construction in Indian Country is taxed under a separate 2 percent special-jurisdiction excise. MMCG maps title status, tribal court jurisdiction, and program eligibility at intake on every reservation-adjacent deal.

The Sioux Falls MSA (Minnehaha, Lincoln, McCook, and Turner counties in South Dakota plus Rock County, Minnesota) reached approximately 315,000 residents in 2025, up close to 10 percent since the 2020 census, with Lincoln County up more than 18 percent over the same period and the City of Sioux Falls at approximately 214,000. Minnehaha and Lincoln counties together account for roughly three-quarters of the state's net migration, and the metro grows at roughly 2.5 to 3 percent per year against a state that grows at well under 1 percent, which means a Sioux Falls absorption model and a statewide absorption model are two different exercises.

The corporate and institutional base is anchored by health care and financial services. Sanford Health, headquartered in Sioux Falls, runs 55,000 employees systemwide across 58 hospitals and 289 clinic locations after its January 2025 combination with Marshfield Clinic, with roughly 11,000 to 12,000 of those in Sioux Falls; Avera Health, also headquartered in Sioux Falls, runs approximately 20,000 employees systemwide. Citi's 1,300-employee card operation, Wells Fargo's 2,000-plus Sioux Falls workforce, First PREMIER Bank and PREMIER Bankcard, and the trust-company cluster documented in Section 1 form the financial layer. Smithfield's existing plant (more than 3,100 jobs), POET's global headquarters, Raven Industries (now CNH Industrial), Midco, Hy-Vee, the Sioux Falls School District, and the Amazon fulfillment center round out the employment base, with CJ Schwan's $550 million, 600-job food plant and Smithfield's $1.29 billion plant in the pipeline. Sioux Falls is the only city in the country where Interstate 29 and Interstate 90 intersect, with the Interstate 229 loop connecting the two, and Foundation Park on the northwest side has become the default location for large-format industrial and food-processing users.

The industrial market entered a hypersupply phase in 2025. Per Bender Commercial's 29th Annual Outlook (February 2026), Sioux Falls industrial vacancy reached a 20-year high in 2025, net absorption fell 20 percent to about 680,000 square feet, roughly 1.1 million square feet of new construction delivered, and asking rents declined modestly, even as investment sales set a record above $160 million on the strength of the Amazon, CJ Schwan's, Silencer Central, and CJ Foods transactions. The office market carries approximately 1.1 million square feet of vacancy, more than 75 percent of it in buildings of 10,000 square feet or larger. Multifamily vacancy ran 9.46 percent in the January 2025 South Dakota Multi-Housing Association survey, up from 6.29 percent in July 2024, and stabilized vacancy finished 2025 near 9.3 percent; the city permitted 1,168 multifamily units in 2025, down from 1,224 in 2024 and from a peak above 3,300 in 2022, and 2025 multifamily sales exceeded $150 million. For any new-construction Sioux Falls apartment study, MMCG stress-tests lease-up against the 2022 to 2024 delivery overhang and models the commercial school levy on the "other" property class explicitly, because a three-plus-unit building in Minnehaha or Lincoln County sits outside the SB 216 owner-occupied cap.

The hotel market is anchored by the Denny Sanford PREMIER Center, the Sanford Sports Complex, the Sanford and Avera medical campuses, and the Interstate 29 and Interstate 90 through-traffic that makes Sioux Falls the largest lodging node between Minneapolis and Denver. Occupancy softened in 2025 and recovered through the first four months of 2026, with occupancy up about 3 percent, rate up about 4 percent, and room demand up 4.6 percent year over year per the city's finance office. Any limited-service or extended-stay study in the metro models the construction-phase lodging demand of the Smithfield and CJ Schwan's builds explicitly rather than assuming it as organic rate growth, and carries the 1 percent municipal gross receipts tax on rooms alongside the state and municipal sales tax.

The Rapid City MSA (Pennington and Meade counties) reached approximately 156,000 residents in 2024, up about 6 percent since 2020, with Pennington County near 117,000 and the City of Rapid City near 85,000 and projected by the city's community development office to approach 100,000 by the 2030 census. Monument Health, anchored by Rapid City Hospital, is the region's largest health system; The Monument (Summit Arena, opened 2021) anchors the events and convention base; and the Elevate Rapid City 128-acre business park, backed by the $7.5 million REDI loan, is the principal new industrial site.

Ellsworth Air Force Base is the single most consequential demand variable in western South Dakota for the next decade. Ellsworth is the first main operating base for the B-21 Raider and home of its Formal Training Unit, with first aircraft delivery on track for 2027. More than $1.6 billion of facility construction is underway; the fiscal year 2025 National Defense Authorization Act added $378 million, bringing B-21 project spending at the base to $1.65 billion since 2021, and a $129.5 million runway reconstruction was completed in December 2025 in a single ten-month season. Base population is projected to grow from about 10,600 to more than 14,000, roughly 4,000 additional personnel, dependents, and civilians. Box Elder, the gate community, grew 21.9 percent between 2022 and 2024 and is projected to exceed 16,000 residents by 2029. The Elevate Rapid City housing study puts the regional shortfall at roughly 5,800 units in Rapid City by 2030 and 9,191 units region-wide, which is why Rapid City carries the highest apartment rents in the state (many above $1,500 per month) against historically tight vacancy in the 1 to 2 percent range, and why the Black Hills Area Community Foundation's Strategic Housing Initiative has delivered or retained 645 affordable units including Sagebrush Flats (179 units, 2025). For any Rapid City or Box Elder multifamily, hotel, self-storage, or retail study, MMCG treats B-21 personnel arrivals as a phased demand schedule keyed to the construction and delivery timeline rather than a lump-sum assumption.

The Black Hills tourism economy is the second anchor. Statewide, visitors spent a record $5.16 billion in 2025 (just under 15 million visitors, up from $5.09 billion and 14.9 million in 2024), generating $406.1 million in state and local tax revenue, supporting roughly 59,000 jobs, and accounting for 16.5 percent of state sales tax collections and $3.7 billion of state GDP per the South Dakota Department of Tourism; the Black Hills and Badlands region alone accounted for approximately $1.98 billion of that spending. Mount Rushmore National Memorial recorded 1,905,649 recreation visits in 2025, up 3 percent, the most-visited National Park Service site in the state; Badlands National Park recorded 1,139,361; Custer State Park drew 2.3 million visitors with roughly $83.7 million in direct economic contribution and about 80 percent out-of-state use; and the state park system as a whole recorded 8.9 million visitors and 341,084 camping nights. The Sturgis Motorcycle Rally (85th edition, August 2025) produced a single-day traffic peak of 68,906 vehicles on August 4 per SDDOT and an estimated 661,000 unique visitors per Placer.ai, and Deadwood's legalized gaming market adds a year-round lodging and entertainment base. For any hotel, RV park, campground, or roadside retail study from Rapid City through Keystone, Hill City, Custer, Hot Springs, Spearfish, Deadwood, and Sturgis, MMCG models the June-through-August peak, the Rally compression week, and the shoulder and winter troughs as separate demand segments with separate rate structures, and applies the 1 percent municipal gross receipts tax to the seasonal revenue curve.

Brookings (approximately 25,000 residents) is the state's university and technology anchor. South Dakota State University enrolled 12,139 students in fall 2025, the largest enrollment in the state, and its Research Park, Daktronics (headquartered in Brookings with more than 1,500 local employees), 3M's Brookings medical products plant, Larson Manufacturing, and Bel Brands' Babybel plant, now doubling under a $200 million expansion through 2028, form the employment base. First Bank & Trust, the state's top 7(a) lender by dollars in fiscal year 2025, is headquartered here. Brookings sits at the southern end of the dairy corridor and 55 miles north of Sioux Falls on Interstate 29, which makes it the most frequently underwritten secondary market in eastern South Dakota for multifamily, student-adjacent housing, hotel, and small-bay industrial product.

Watertown (Codington County, approximately 23,000 residents) is the corridor's manufacturing and biofuel node, anchored by Terex Utilities, Glacial Lakes Energy's ethanol headquarters, Lake Area Technical College, and Prairie Lakes Healthcare, with Agropur's Lake Norden plant 20 miles to the south and Valley Queen Cheese in Milbank 40 miles to the northeast. Aberdeen (Brown County, approximately 28,000 residents, the state's third-largest city) anchors the northern corridor with Northern State University, the AGP soybean plant, Agtegra Cooperative's headquarters, 3M's Aberdeen plant, and the Avera St. Luke's and Sanford Aberdeen hospitals; the Applied Digital data center complex at Ellendale, North Dakota, 40 miles north, has become a measurable source of construction-phase and vendor demand for Aberdeen lodging and retail. For northeast South Dakota rural deals, the USDA Rural Development area offices in Aberdeen and Watertown are the correct first-contact points, and the Sisseton-Wahpeton Oyate's Lake Traverse Reservation, spanning parts of Roberts, Marshall, Day, Codington, and Grant counties, places title and jurisdiction questions at the front of any project north of Watertown.

Mitchell (Davison County) is now the state's soybean-crushing capital following the September 9, 2025 opening of High Plains Processing's $500 million plant, the highest-value construction project in the city's history, layered on Trail King Industries (the city's largest manufacturing employer), the POET Mitchell ethanol plant, Dakota Wesleyan University, Avera Queen of Peace Hospital, and the Corn Palace tourism draw on Interstate 90. Huron (Beadle County) hosts the USDA Rural Development State Office, the Dakota Provisions turkey processing plant, the South Dakota State Fair, and Huron Regional Medical Center. Yankton (Yankton County, approximately 15,000 residents) is anchored by Kolberg-Pioneer, an Astec Industries company, Avera Sacred Heart Hospital, Mount Marty University, and the Gavins Point Dam and Lewis and Clark Lake recreation complex on the Missouri River, which drives a marina, RV park, and seasonal lodging demand base that no inland South Dakota market replicates. Vermillion (Clay County) is the University of South Dakota's home, and Pierre (Hughes County, approximately 14,000 residents), the state capital, carries a government-employment floor and the Lake Oahe recreation economy. Each of these markets is USDA rural-eligible in whole or in substantial part, and each is close enough to Interstate 29 or Interstate 90 that the corridor traffic count, not the local population, is the primary demand variable for fuel, convenience, and lodging product.

South Dakota's agricultural economy runs on three distinct production geographies, each with its own USDA Rural Development thesis. The corn-soybean-ethanol belt east of the Missouri River supports the 16-plant ethanol industry, the High Plains Processing and AGP crush plants, and a growing sustainable aviation fuel pipeline; the Interstate 29 dairy corridor from Sioux Falls north through Brookings, Lake Norden, Watertown, and Milbank has become the fastest-growing dairy region in the country, with the state herd more than doubling from 91,000 cows in 2012 to 215,000 on January 1, 2025 and milk output rising from 2 billion pounds in 2013 to 4.5 billion pounds in 2023; and the west river cattle economy supports 3.55 million head of cattle and calves, the seventh-largest inventory in the nation, on a ranch and feedlot base that has drawn a wave of small and mid-scale processing proposals after the $1.1 billion, 8,000-head-per-day Western Legacy plant proposed for Rapid City failed to advance. MMCG treats every proposed South Dakota beef plant as a sponsor-capacity and procurement question first, because the state's recent record is that small plants of the I-90 Meats scale ($21 million, 30,000 square feet, New Underwood) reach financing and the mega-plant proposals do not.

Confined animal feeding operations are permitted under a Department of Agriculture and Natural Resources general permit, now available on ten-year terms, and sited under county zoning through conditional-use permits and setback ordinances that vary materially county to county. For any USDA Business and Industry or REAP deal with a dairy, swine, or feedlot nexus, MMCG confirms the DANR permit status and the county's conditional-use posture at intake, before any capacity or revenue line is modeled, because a project that cannot clear the county board cannot be financed regardless of the strength of the financial model. The REAP pipeline runs through the rural electric cooperatives (East River Electric's member systems in the east, Rushmore Electric's in the west, and Basin Electric behind both), covering on-farm solar, grain-drying efficiency, livestock-facility ventilation, and the ethanol-plant efficiency projects that drew the October 2024 award to Aberdeen Energy; MMCG calibrates the REAP analysis to the cooperative territory, the grant percentage available (up to 50 percent of eligible cost), and whether the application is competing in a grant round or a guaranteed-loan round, a distinction that moves effective cost of capital by 200 to 400 basis points.

Beyond the processing, financial-services, defense, and tourism anchors, MMCG is a feasibility study consultant that produces lender-grade feasibility studies across the full range of South Dakota asset classes. Self-storage demand is calibrated to the Sioux Falls growth ring in Harrisburg, Tea, Brandon, and northwest Sioux Falls, to the Box Elder and Rapid Valley corridor east of Rapid City where B-21 personnel rotation generates above-average storage demand per household, and to the Brookings, Watertown, and Aberdeen regional markets. Hotel and hospitality feasibility spans the Sioux Falls events and medical base, the Interstate 90 corridor from Sioux Falls through Mitchell, Chamberlain, Wall, and Rapid City, the Black Hills leisure market with its Sturgis and summer compression, and the Deadwood gaming market. RV park and outdoor-hospitality feasibility draws on Custer State Park, Keystone, Hill City, Hot Springs, and Spearfish Canyon in the west, on the Missouri River reservoir system at Lake Oahe, Lake Sharpe, Lake Francis Case, and Lewis and Clark Lake, and on the glacial lakes region around Watertown, with explicit seasonality modeling for the May-through-September season and the Rally week. Gas station, convenience, travel center, and car wash feasibility is calibrated to Interstate 29 and Interstate 90 traffic counts and the Sturgis peak, with Casey's, Kum & Go and Maverik, Cenex and CHS, Love's, and Pilot competitive sets modeled directly and the contractor's excise tax carried through the canopy, tank, and tunnel budgets. Assisted living, memory care, and senior housing feasibility is matched to a state with roughly 174,000 residents age 65 and older, about 19 percent of the population and its fastest-growing cohort, and to the Sanford, Avera, and Monument Health referral networks. Childcare feasibility addresses a state with roughly 73,000 children under age six and an estimated 34,500 licensed child-care slots, and with nearly three-quarters of those children in households where both parents work, a shortfall that supports USDA Community Facilities financing for non-profit operators across the rural-eligible counties. Each asset class is benchmarked against the relevant South Dakota submarket comparable set rather than national averages, with the dual construction tax, the three-class property levy, the municipal gross receipts tax, and the USDA and GOED program eligibility all modeled directly where relevant.

First, the contractor's excise tax and the materials sales tax must appear as separate lines in every South Dakota construction budget a feasibility study firm submits to a lender. The 2 percent excise on gross contract receipts (recovered at the 2.041 percent bid factor) plus 4.2 percent sales and use tax on materials, rising to 4.5 percent on July 1, 2027, adds roughly three points to hard cost relative to a no-income-tax peer like Wyoming and is routinely omitted from out-of-state cost templates.

Second, the July 1, 2027 sales tax reversion is a scheduled fact, not a forecast. HB 1137's sunset stands, the 2024 and 2026 efforts to make 4.2 percent permanent failed, and SB 245 has already allocated the reversion revenue. Any draw schedule or stabilized revenue projection that crosses July 1, 2027 models the higher rate.

Third, SB 216's 3 percent assessment cap protects owner-occupied homes only. Commercial and agricultural property in every county remains fully exposed to reassessment and to levy growth, and the failure of HB 1253 on March 9, 2026 confirms that no commercial cap is coming in the near term. MMCG models the commercial school levy from the county levy sheet and stress-tests a levy shift toward the "other" class as residential relief is layered in.

Fourth, the bank franchise tax replaces the corporate income tax for financial-institution sponsors. A trust company or credit card bank sponsor is modeled at the graduated 10-43 rate on its own net income bracket, not at zero and not at a borrowed corporate rate from a neighboring state.

Fifth, the 1 percent municipal gross receipts tax on lodging, prepared food, alcohol, and admissions is a stabilized revenue line item in every South Dakota hotel, restaurant, entertainment, and RV resort pro forma, layered on the state and municipal sales tax and modeled to the specific municipality.

Sixth, South Dakota has no data center tax exemption and adopted siting restrictions on large data centers in March 2026. Energy-intensive industrial studies model the utility's published large-load rate without an incentive overlay and treat interconnection and local approval as explicit risks, in direct contrast to the Iowa, Nebraska, and North Dakota frameworks.

Seventh, HB 1052's eminent domain ban for carbon dioxide pipelines is a permanent input to every ethanol, sustainable aviation fuel, and biorefinery study. The Section 45Z credit is modeled without an assumed sequestration pathway, and the with-carbon-capture case is presented as upside optionality rather than the base case.

Eighth, Ellsworth's B-21 program is a phased demand schedule. Roughly 4,000 additional personnel, dependents, and civilians arrive against a first aircraft delivery in 2027 and a base population above 14,000 thereafter; MMCG keys Rapid City and Box Elder absorption to that timeline and to the documented 5,800-unit housing shortfall rather than to a single-year population jump.

Ninth, the county conditional-use permit is the binding constraint on any livestock-adjacent deal. No USDA Business and Industry or SBA 7(a) analysis on a dairy, swine, or feedlot project is defensible without a confirmed DANR permit and a cleared county zoning posture; MMCG obtains both determinations at intake.

Tenth, Indian Country title and jurisdiction determine collateral on every reservation-adjacent deal. Fee versus trust status, Bureau of Indian Affairs leasehold approval, tribal court jurisdiction over foreclosure, and the separate 2 percent special-jurisdiction excise on construction are resolved before the capital stack is modeled, not discovered at closing.

A South Dakota engagement with MMCG as feasibility study consultant begins with the project address, asset class, total capitalization, sponsor structure, sponsor experience, and the specific lender, CDC, or Governor's Office of Economic Development contact carrying the deal. MMCG confirms SBA SOP 50 10 8 applicability, and SOP 50 10 8.1 applicability for any application submitted on or after October 1, 2026, across the single South Dakota District Office geography; the USDA program of record (Business and Industry, REAP, Community Facilities, or Water and Environmental Programs) administered from the Huron State Office and the relevant area office; and the South Dakota state stack, meaning REDI Fund and Reinvestment Payment Program or South Dakota Jobs Program qualification, Housing Infrastructure Financing Program and Low-Income Housing Tax Credit posture where housing is involved, tax increment district status and classification for any municipal deal, Opportunity Zone status, DANR permit status for any livestock-adjacent project, and title and jurisdiction status for any project on or adjacent to one of the nine reservations. A complimentary preliminary South Dakota market overview is delivered within one business day of submission, before any fee is collected, and includes the construction tax estimate at the 2.041 percent bid factor with the July 1, 2027 reversion flagged, the county levy-sheet property tax estimate on the commercial class, the municipal sales and gross receipts tax stack for the host municipality, and the applicable USDA or GOED program eligibility determination.

The study itself is built around four analyses calibrated to the South Dakota deal: an Economic Analysis (the trust and card-services employment base for any Sioux Falls office or mixed-use study; the Ellsworth B-21 schedule and the Black Hills visitor economy for any west river project; the dairy, soybean, ethanol, and pork processing context for any USDA rural deal; and the no-income-tax, bank franchise tax, and contractor's excise tax structure for any sponsor return projection), a Market Feasibility Analysis (parcel-level absorption, comparable performance, ADR or rent benchmarks, and competitive position across the relevant South Dakota submarket, with every competitor verified at source), a Technical Feasibility Analysis (site, entitlement, county conditional-use posture, DANR permitting where livestock or large industrial uses are present, large-load interconnection where relevant, and constructability with the dual construction tax quantified in the hard cost budget), and a Financial Feasibility Analysis (stabilized assumptions, lease-up curve, discounted cash flow through stabilization and reversion, debt service coverage at the lender-required threshold, equity injection mechanics under the applicable SOP, property tax modeled from the county levy sheet on the commercial class, the municipal gross receipts tax modeled on the revenue lines it touches, and the GOED, South Dakota Housing, and tax increment schedule quantified rather than asserted). Draft delivery goes to the sponsor and the lender, CDC, or GOED contact simultaneously, with the review cycle through final lender acceptance accommodated and no additional fees for normal-course revision rounds.

Pricing starts at $4,900 with a 50/50 fee schedule. Delivery in 9 to 16 business days, with rush turnaround available from 5 days. Engagement begins with the project address, the sponsor structure, the program of record, and the participating lender, CDC, county or municipal economic development office, or Governor's Office of Economic Development contact.

MMCG is a feasibility study firm that produces feasibility studies across the six states bordering South Dakota, allowing multi-state sponsors and regional lenders to route an entire northern Plains pipeline through a single feasibility study consultant. Minnesota lies across the eastern border, where Rock County now sits inside the Sioux Falls MSA and where a 9.85 percent top individual income tax rate against South Dakota's zero drives a persistent flow of residents and closely held businesses into Lincoln and Minnehaha counties; Iowa lies to the southeast, where the Sioux City tri-state market spans Union and Clay counties on the South Dakota side and where Iowa's 3.8 percent flat individual rate for tax year 2026 narrows but does not close the differential; Nebraska lies to the south across the Missouri River, where the Tyson Dakota City beef complex draws South Dakota-resident labor and where Prestage Wholestone's operating pork plant sits, and where the individual rate is phasing down toward 3.99 percent by 2027; North Dakota lies to the north, where the Applied Digital data center complex at Ellendale spills construction and vendor demand into Aberdeen and where the Standing Rock and Lake Traverse reservations cross the state line; Montana lies to the northwest across the ranch country of Harding and Butte counties; and Wyoming lies to the west, where the Black Hills extend into Crook and Weston counties, where the Gillette energy corridor connects to Rapid City along Interstate 90, and where the absence of any income tax matches South Dakota's own. Cross-border deals involving the Sioux Falls-Minnesota commuter shed, the Sioux City tri-state processing belt, the Aberdeen-Ellendale data center corridor, and the Rapid City-Gillette Interstate 90 corridor are calibrated to the regulatory, tax, and incentive framework on each side of the line.

MMCG produces feasibility studies in every South Dakota county and municipality, including Sioux Falls, Rapid City, Aberdeen, Brookings, Watertown, Mitchell, Yankton, Pierre, Huron, Spearfish, Vermillion, Brandon, Box Elder, Sturgis, Madison, Belle Fourche, Harrisburg, Tea, Hot Springs, Milbank, Lead, Deadwood, Custer, Keystone, Hill City, Wall, Chamberlain, Mobridge, Winner, Sisseton, Redfield, Dell Rapids, Canton, Lennox, Beresford, Elk Point, North Sioux City, Dakota Dunes, Volga, Lake Norden, Freeman, Parkston, Wagner, Platte, Gregory, Martin, Pine Ridge, Mission, Eagle Butte, and Fort Thompson.

The 66 South Dakota counties served, by region: Minnehaha, Lincoln, Turner, McCook, Union, Clay, Yankton, Bon Homme, Hutchinson, Moody, Lake, Hanson, Davison, Douglas, and Charles Mix in the Sioux Falls Metro and Southeast; Brookings, Codington, Brown, Grant, Deuel, Hamlin, Kingsbury, Day, Roberts, Marshall, Clark, Spink, Edmunds, McPherson, and Miner in the Northeast, the I-29 Corridor, and the Glacial Lakes; Beadle, Hughes, Stanley, Sully, Hyde, Hand, Faulk, Potter, Walworth, Campbell, Jerauld, Sanborn, Aurora, Brule, Buffalo, Lyman, Jones, Gregory, Tripp, and Haakon in Central South Dakota, the James River Valley, and the Missouri River Reservoir Country; and Pennington, Meade, Lawrence, Custer, Fall River, Butte, Harding, Perkins, Corson, Dewey, Ziebach, Jackson, Bennett, Mellette, Todd, and Oglala Lakota in the Black Hills and West River.

The nine reservations, with the counties they occupy in whole or in part: Pine Ridge (Oglala Lakota, Bennett, and Jackson counties), Rosebud (Todd County, with trust land in Tripp, Mellette, Gregory, and Lyman), Cheyenne River (Dewey and Ziebach counties), Standing Rock (Corson County, extending into North Dakota), Lower Brule (Lyman and Stanley counties), Crow Creek (Buffalo, Hughes, and Hyde counties), Yankton (Charles Mix County), Flandreau Santee Sioux (Moody County), and Lake Traverse (Roberts, Marshall, Day, Codington, and Grant counties).
