M&A Advisory in Minnesota

Minnesota imposes a flat 9.8% corporate franchise tax on C-corp net income (Minn. Stat. ch. 290) — 3rd-highest top corporate rate in the US — plus a 5.8% corporate AMT and a graduated minimum-fee add-on based on MN property/payroll/sales. Pass-through entities could elect Minnesota's PTE tax at 9.85% as a SALT-cap workaround, but the PTE election expires for tax years beginning after December 31, 2025 per the MN DOR's November 21, 2025 update, unless the 2026 legislature extends it. Deals closing in 2026+ must plan for owner-level Minnesota tax with the federal SALT cap raised to $40,000 through 2029 under OBBBA.

Minnesota does NOT provide a preferential long-term capital gains rate — all capital gains are taxed as ordinary income at graduated rates up to 9.85% (top bracket roughly $200K+ single / $330K+ MFJ for 2025). Effective for tax years beginning after December 31, 2023, Minnesota added a 1% surtax on net investment income exceeding $1 million (Schedule M1NIIT), bringing the effective top marginal rate on large investment gains to 10.85%. A founder selling for a $10M+ gain triggers both the 9.85% top bracket and the 1% surtax on gain above $1M; installment sales, CRTs, and pre-sale residency changes are common mitigation strategies, but Minnesota aggressively scrutinizes residency using a 26-factor domicile test.

Minnesota fully conforms to IRC §1202 at both the corporate and individual level via Minn. Stat. § 290.01(19), meaning gain excluded federally on Qualified Small Business Stock is also excluded from Minnesota taxable income. Under post-OBBBA rules (for stock issued after July 4, 2025), the exclusion cap rises to $15M or 10x basis. Minnesota residents can stack the federal exclusion with full state exclusion — saving up to 10.85% Minnesota tax on excluded gain. For Twin Cities medtech, SaaS, and manufacturing C-corps, properly structured early-stage QSBS planning is one of the most valuable Minnesota planning tools available.

Minnesota imposes a deed/transfer tax of 0.33% (Minn. Stat. ch. 287) on real property transfers, with an additional 0.01% Environmental Response Fund tax in Hennepin and Ramsey counties. Equipment and certain software transferred in an asset sale can attract Minnesota's 6.875% state sales tax (8.13% combined average) unless an occasional-sale exemption applies. Critically, Minn. Stat. § 270C.57 imposes successor liability on bulk asset transfer buyers for seller's unpaid sales, withholding, and petroleum taxes — buyers must file Form C50 at least 20 days before closing and obtain DOR clearance or risk personal liability up to the purchase price.

Minnesota is one of ~12 states with a stand-alone estate tax: a $3,000,000 per-person exemption (NOT indexed for inflation, NOT portable between spouses), with graduated rates from 13% to 16% (top rate above $10.1M of taxable estate). Minnesota also claws back taxable gifts made within 3 years of death. A Qualified Small Business and Farm Property Deduction (Schedule M706Q) of up to $2,000,000 brings the effective shelter to $5M for qualifying estates — but strict rules apply: ≤$10M gross sales, 3-year pre-death ownership, and a 16% recapture tax on premature disposition. Pre-sale gifting to grantor trusts, IDGTs, and ILITs are critical for $3M+ estates.

Minnesota's Angel Investment Tax Credit (administered by DEED) provides a refundable 25% credit to certified accredited investors in qualifying high-tech or medtech MN small businesses, capped at $125,000 per individual annually; minimum qualifying investment is $10,000. Minnesota also offers an R&D Credit of 10% on the first $2M of qualifying Minnesota R&D expenses and 2.5% on amounts above $2M (Minn. Stat. § 290.068). For Twin Cities medtech and software sellers, undocumented R&D credit positions are a frequent due-diligence finding — properly substantiated credits can enhance valuation by demonstrating Minnesota tax-attribute carryforwards available to acquirers.
