Minnesota Estate Tax Calculator 2026
Estimate Minnesota estate tax from the filing-threshold estate, state taxable estate, official exclusion or credit, and state situs share. Inputs map to the concepts used on M706 rather than treating gross estate and taxable estate as the same number.
Use gross estate plus gifts or prior QTIP amounts required by M706.
Start from the federal or pro-forma estate tax return and reflect allowable deductions.
Calculator cap: $2,000,000.
Use 100% when the full tax base is attributable to Minnesota; consult M706 for resident/nonresident apportionment.

What the official M706 rules change
- •The qualified farm and small-business deduction is capped at $2 million for 2026.
- •Taxable gifts made within three years of death can enter the Minnesota calculation.
- •The return and payment are generally due nine months after death.
This is a planning estimate. QTIP elections, alternate valuation, special-use valuation, property classification, deductions, prior gifts, and nonresident apportionment require the official return and may change the result.
Frequently asked questions
What is the Minnesota estate tax threshold for 2026?
Minnesota uses a $3,000,000 filing threshold for this calculator. Filing tests can use gross-estate and gift amounts that differ from the taxable estate used to calculate tax.
What is the top Minnesota estate tax rate?
The top rate is 16%. Lower brackets, credits, exclusions, and situs apportionment can materially reduce the effective rate.
When is M706 due?
M706 is generally due nine months after the date of death. An extension to file ordinarily does not automatically extend the payment deadline.
Does the federal estate tax exemption replace the Minnesota threshold?
No. Minnesota applies its own filing threshold and calculation. An estate can owe state estate tax even when no federal estate tax is due.
