Tax Calculator

Minnesota imposes a state estate tax with an exemption of **$3 million**. The tax applies graduated rates from 13% to 16% on taxable estates above the exemption.

Minnesota's exemption was raised from $2.4 million to $3 million in 2020, bringing modest relief but still capturing a meaningful number of estates, particularly those with agricultural land or closely held business interests.

Unlike cliff-effect states, Minnesota taxes only the excess above the exemption, with a phase-in provision that reduces the exemption for estates between $3 million and $3.6 million. This phase-in creates a de facto marginal rate spike in that narrow band — model it carefully before finalizing an estate plan.

The $15 million federal exemption dwarfs Minnesota's **$3 million** exemption. Minnesota does not offer portability of its state exemption, so surviving spouses cannot claim the deceased spouse's unused exemption.

This makes credit shelter trust planning critical for married couples in Minnesota.

Minnesota does allow a deduction for qualified small business property (QSBP) and qualified farm property (QFP) up to $5 million, which can dramatically reduce or eliminate the state estate tax for agricultural and small business estates. This deduction is unique to Minnesota and has no federal analogue.

Farm families and business owners or closely held business owners should evaluate eligibility carefully.

The QSBP and QFP deductions are subject to a 3-year recapture provision: if the property is sold or transferred within three years of death, the estate tax benefit is recaptured. When drafting estate plans for farming families, structure business succession plans to avoid triggering recapture.

Minnesota's income tax rate (up to 9.85%) also affects estate planning. Grantor trusts that shift income to lower-tax jurisdictions have come under increased scrutiny.

Minnesota taxes trusts with a Minnesota resident beneficiary or trust created by a Minnesota grantor, so trust siting decisions require careful analysis of Minnesota's trust taxation rules under M.S. 290.01.

Minnesota residents with taxable estates face a two-layer system: the federal estate tax (exemption of $15 million in 2025, top rate of 40%) and the Minnesota estate tax (exemption of $3 million). The gap between these exemptions creates a range where only the state tax applies.

An estate valued at $8 million, for example, may owe Minnesota estate tax while owing nothing at the federal level.

The federal return (Form 706) allows a deduction for state estate taxes paid, which partially offsets the double-taxation effect but does not eliminate it. The state tax is deductible on the federal return as an estate administration expense or under the state death tax credit rules, depending on the estate's circumstances.

The net result is that combined effective rates in Minnesota can exceed 45% on estates large enough to trigger both layers.

Planning for this interaction requires modeling both taxes simultaneously. Strategies that reduce the Minnesota taxable estate — such as lifetime gifts, charitable bequests, and irrevocable trusts — may also reduce federal exposure, but the relative benefit depends on where the estate falls within each jurisdiction's rate brackets.

Use our Minnesota estate tax calculator to model both layers side by side, and check the Minnesota probate cost calculator to estimate administration expenses.

Federal law permits a surviving spouse to use the deceased spouse's unused exclusion (DSUE) — commonly called portability — by timely filing Form 706 for the first-to-die spouse. This allows married couples to shelter up to $30 million federally without trust-based planning.

However, most estate-tax states, including Minnesota, do not offer portability of the state exemption.

This asymmetry makes bypass trusts (also called credit shelter trusts or B trusts) essential in Minnesota. At the first spouse's death, funding a bypass trust up to the Minnesota exemption amount preserves that exemption for state tax purposes.

Without the trust, the unlimited marital deduction passes everything to the surviving spouse tax-free at the first death — but the surviving spouse's estate then has only one Minnesota exemption, effectively wasting the first spouse's.

The bypass trust should be sized carefully. Overfunding it beyond the Minnesota exemption wastes the marital deduction benefit; underfunding it fails to capture the full state exemption.

For married couples with estates above $3 million but below $15 million, the bypass trust is the single most impactful planning tool available. Review your plan with the Minnesota estate tax estimator, and use the executor fee calculator to account for administration costs in your projections.

The $3 million Minnesota exemption establishes a lower threshold than the federal exemption, making proactive estate reduction strategies more urgent. Irrevocable trusts are the primary vehicle: irrevocable life insurance trusts (ILITs) remove life insurance proceeds from the taxable estate, spousal lifetime access trusts (SLATs) allow married couples to remove assets while retaining indirect access, and qualified personal residence trusts (QPRTs) transfer a home at a discounted gift tax value.

Annual exclusion gifting — currently $19,000 per recipient (2025) — reduces the taxable estate dollar-for-dollar without consuming the lifetime gift exemption. For Minnesota residents near the $3 million threshold, a sustained gifting program over several years can bring the estate below the state exemption entirely.

Charitable remainder trusts (CRTs) and charitable lead trusts (CLTs) offer additional reduction while generating income tax deductions.

GRATs (grantor retained annuity trusts) are particularly effective in low-interest-rate environments, transferring asset appreciation to beneficiaries with minimal or zero gift tax cost. For Minnesota business owners, entity-level planning — family limited partnerships, LLCs with valuation discounts, and buy-sell agreements — can reduce the reportable value of closely held interests for both state and federal purposes.
