The Basics
What Cost Segregation Does for Minnesota Property Owners
A cost segregation study identifies building components, HVAC systems, specialty flooring, parking surfaces, interior finishes, exterior lighting, that qualify for accelerated depreciation on 5-, 7-, or 15-year schedules rather than the default 27.5-year (residential rental) or 39-year (commercial) building schedule. Front-loading those deductions increases first-year cash flow and lowers current-year federal taxable income.
In Minnesota, the federal benefit works the same way it does anywhere, the One Big Beautiful Bill (OBBBA, P.L. 119-21) permanently restored 100% bonus depreciation for qualified property placed in service after January 19, 2025, and that federal benefit applies to Minnesota properties in full. State-level treatment is where Minnesota is different: Minnesota partially conforms to §168(k) via a 20/80 mechanic, taxpayers add back 80% of federal bonus depreciation in the year the property is placed in service, then subtract 1/5 of that addback in each of the following five tax years. Effectively, Minnesota allows 20% of federal bonus in Year 1 and the remaining 80% ratably over the next five years. Under Minnesota’s 2026 omnibus tax bill (H.F. 2438), Minnesota updated conformity to the IRC through May 1, 2026, adopting OBBBA’s 179 increases and other provisions, but the 80% addback mechanic on 168(k) bonus depreciation remains in effect. [VERIFY current 2026 MN 168(k) treatment per final H.F. 2438 language, sources indicate the addback mechanic continues.]
Federal Deduction Amplified by MN’s High Marginal Rates
Minnesota’s Tax Landscape: Why Cost Segregation Matters Here
Individual Income Tax
Graduated to 9.85% top rate on ordinary income, among the highest in the country. Minnesota also imposes a 1% surtax on net investment income over $1M (creating a top rate on long-term capital gains that exceeds the top rate on ordinary income).
Corporate Franchise Tax: 9.8% Flat
on Minnesota taxable income. Minnesota also imposes a corporate Alternative Minimum Tax (AMT).
Bonus Depreciation Conformity
Partial conformity. Minnesota applies an 80% addback + 1/5 subtraction over 5 years mechanic for federal §168(k) bonus depreciation. Effectively spreads bonus over 6 tax years at the Minnesota state level.
§179 Expensing
Under H.F. 2438 (2026), Minnesota adopts OBBBA’s expanded §179 limits ($2.5M cap indexed to $2.56M for 2026; $4M phase-out threshold).
PTE (Pass-Through Entity) Tax
Minnesota’s PTE tax election extended through 2027 (H.F. 2438). Pass-through entities can elect to pay Minnesota tax at the entity level for federal SALT-cap workaround purposes.
Property Tax
~1.05% effective on owner-occupied housing. A separate lever from income tax; cost segregation operates on income tax through accelerated depreciation.
§481(a) Catch-Up
For Minnesota properties owned more than a year without a study, an automatic accounting-method change (Form 3115 under Rev. Proc. 2015-13 and its updates) captures all missed depreciation into the current tax year at the federal level, no amended returns required.

Real Numbers
What First-Year Savings Might Look Like in Minnesota
Results depend on property type, cost basis, construction year, and applicable depreciation rates, and we run a free benefit analysis before you commit to a study so you can see projected numbers first.
As a reference point, an Ambrose Group engagement on a $2.9M commercial property delivered $657,692 in first-year depreciation increase and $230,192 in first-year tax savings. In Minnesota specifically, the federal Year 1 savings apply fully. Minnesota state benefit is spread over six years due to the 80% addback + 1/5 subtraction mechanic, but the total Minnesota benefit is preserved, just timed differently. Given Minnesota’s 9.85% top individual rate and 9.8% corporate rate, the combined federal + state benefit (once fully recovered) is substantial.

Cost Segregation in Minnesota
Frequently Asked Questions
Does Minnesota conform to federal bonus depreciation rules?
Partial conformity. Minnesota applies an 80% addback + 1/5 subtraction over five years mechanic for federal §168(k) bonus depreciation, effectively allowing 20% of federal bonus in Year 1 and the remaining 80% ratably over the next five years. Under H.F. 2438 (Minnesota’s 2026 omnibus tax bill), Minnesota updated conformity to the IRC through May 1, 2026, but the 80% addback mechanic on bonus depreciation continues. Your federal Year 1 tax savings from a cost segregation study are fully preserved.
How does Minnesota’s income tax structure interact with a cost segregation study?
Minnesota has a graduated individual income tax topping at 9.85%, among the highest in the country. Corporate franchise tax is 9.8% flat, plus Minnesota imposes a corporate Alternative Minimum Tax (AMT). Because Minnesota applies the 80% addback + 5-year subtraction mechanic, the state-level benefit is spread over six years, but the total benefit is preserved. Given Minnesota’s high marginal rates, once fully recovered, the state-side benefit is substantial.
What about Minnesota’s §179 cap?
Under H.F. 2438 (2026), Minnesota adopts OBBBA’s expanded §179 limits, $2.5M cap (indexed to $2.56M for 2026) with a $4M phase-out threshold. This is a favorable change from prior Minnesota law.
What Minnesota commercial property types benefit most from cost segregation?
Twin Cities Fortune 500 corporate headquarters and Class A office, Mayo Clinic Rochester healthcare complex, medical device manufacturing (Medtronic, Boston Scientific), 3M, Polaris, and Toro manufacturing, and Twin Cities multifamily. Medical device manufacturing and specialty healthcare typically deliver the strongest results due to heavy specialty equipment content.
Can I do a cost segregation study on a Minnesota property I’ve owned for years?
Yes, A §481(a) adjustment via an automatic accounting-method change (Form 3115 under Rev. Proc. 2015-13 and its updates) lets you capture all missed depreciation from prior years into the current tax year without amending past returns. Especially valuable for long-held Minnesota corporate office, manufacturing, and Mayo Clinic-corridor healthcare properties.
How do you do a cost segregation study on a Minnesota property when you’re based in Texas?
Cost segregation is governed by federal tax law, so the methodology is identical regardless of state. Our engineer works either through an in-person Minnesota site visit or, for well-documented properties, a virtual site inspection using high-definition video, construction documents, and interactive tools. Both are IRS-compliant.
What construction era of Minnesota property produces the strongest cost segregation outcomes?
Properties placed in service since 1987 are eligible under current IRS guidance, and studies limited to the last 7–10 years tend to deliver the strongest ROI. Twin Cities corporate office reinvestment, Mayo Clinic expansions, medical device facility buildouts, and Twin Cities multifamily development have produced substantial newer commercial property in the ideal window.
Does Minnesota’s property tax rate affect the cost seg decision?
Not directly. Cost segregation reduces income tax through accelerated depreciation, not property tax. Minnesota’s owner-occupied effective property tax rate is around 1.05% (moderate). Property tax is a separate lever from the income-tax benefit cost segregation delivers.
What documentation do you need for a Minnesota cost segregation study?
Purchase or construction cost documentation, a current depreciation schedule from your CPA, construction plans or specs (when available), any prior appraisals, and, for renovation studies, improvement records. Because Minnesota applies the 80% addback + 1/5 subtraction mechanic, your CPA will need the detailed asset schedule to manage the six-year state recovery. We provide it as part of the standard deliverable.
Can you handle Minnesota multi-property portfolios? How long does a study take?
Yes, we regularly run cost segregation studies across multi-state and Minnesota-only portfolios. Common for Twin Cities corporate office portfolios, Medtronic and other medical device operators with multiple facilities, and Twin Cities multifamily portfolio owners. Typical study timeline is 4–8 weeks per property; complex medical device and pharma facilities take longer proportional to the specialty-equipment cataloging effort.
