Quick answer: Minnesota taxes the gain as ordinary income, at graduated rates up to 9.85% — there's no reduced rate for holding the property longer, unlike the federal system. See the full cost picture in the Minnesota probate real estate sale calculator.
No long-term discount, unlike federal tax
A 1% surtax on genuinely large gains
Minnesota's 2023 omnibus tax bill (HF 1938) created an additional 1% tax on net investment income above $1 million — a state-level surtax separate from, and stacked on top of, the federal 3.8% Net Investment Income Tax. Relevant mainly for unusually large estates or gains, not a typical family home sale.
The stepped-up basis still does most of the work
Under federal law (IRC § 1014), an inherited house's basis resets to its fair market value on the date of death. Sell soon after death, near that same value, and the taxable gain — state and federal — is small or zero, regardless of Minnesota's lack of a long-term discount.
A separate estate tax, no portability
Minnesota has its own state estate tax with a $3,000,000 exemption and rates of 13% to 16% — not portable between spouses without advance planning, unlike the federal exemption. Minnesota has no separate inheritance tax.
A worked comparison
For a large long-term gain sitting in the top brackets, the combined federal and Minnesota rate can approach roughly 30% — since Minnesota's 9.85% has no long-term discount to offset it, unlike a state that mirrors the federal preferential treatment.
A local probate attorney can review your estate — many offer a free consultation.
The graduated brackets and the $1 million surtax threshold apply identically whether the sale closes in Hennepin, Ramsey, Dakota, or Anoka County — Minnesota has no local income tax layered on top.
