Most Minnesotans assume the estate tax is a problem for the very rich — people with private planes and generational wealth. When it comes to the federal estate tax, that’s basically true. But Minnesota runs its own estate tax on a much lower threshold, and it catches a lot of people who would never describe themselves as wealthy: retirees with a paid-off house, small-business owners, and family farmers.
This article explains the “trap” in plain terms — why a Minnesota estate can owe state tax while owing zero federal tax, why married couples are especially exposed, and how trusts and other tools are commonly used to address it. It is general information, not legal or tax advice; the right approach depends on details only an estate planning attorney and a tax advisor can sort out for you.
The core trap: Minnesota’s threshold is far below the federal one
Here is the gap that surprises people.
For deaths in 2025, the federal estate tax exemption is $13,990,000 per person, and for 2026 it rises to $15,000,000 per person (source: IRS inflation-adjustment announcement for tax year 2026). An estate under those figures owes no federal estate tax at all.
Minnesota is a different story. Minnesota’s estate-tax exclusion is $3,000,000 for decedents dying in 2025 (source: Minnesota Department of Revenue, 2025 Form M706 instructions; Minn. Stat. § 291.016, subd. 3, sets the same $3,000,000 figure for deaths in 2020 and later). An estate above $3,000,000 has to file a Minnesota estate tax return and may owe Minnesota estate tax — even if it owes nothing to the IRS.
That is more than a $10 million spread between the point at which Minnesota starts taxing and the point at which the federal government does. A Minnesota family can be comfortably below the federal line and squarely above the state line.
The reason so many people are caught off guard is what counts as your “estate.” For Minnesota estate-tax purposes, the taxable estate generally starts from the fair market value of everything you own at death, before subtracting the exclusion. That includes:
- Home equity — often the biggest single number, especially after decades of Minnesota real-estate appreciation
- Retirement accounts — 401(k)s, IRAs, and similar accounts
- Life insurance proceeds on a policy you own — the full death benefit, not just the premiums you paid
- Business or farm value
- Investment and bank accounts
Suppose a Minnesota couple in their late sixties: a paid-off home worth $650,000, combined retirement accounts of $1.4 million, a $750,000 life insurance policy, a small business valued at $500,000, and about $300,000 in savings and investments. None of that feels like “rich.” But it adds up to roughly $3.6 million — over the Minnesota threshold. That is the trap: the number sneaks up on ordinary savers, homeowners, and business owners who never thought the estate tax applied to them.
This is still a minority of estates. Of the nearly 50,000 deaths reported in Minnesota in 2023, only 318 estates paid the estate tax (source: Minnesota House Research Department, The Minnesota Estate Tax, November 2025). But “rare” is cold comfort if your family is one of the 318 — and the families most likely to be caught are the ones who assumed they were safe.
The rates: 13% to 16%
Minnesota’s estate tax is graduated. There are five rates and brackets. The bottom rate is 13 percent, applying to the taxable estate up to $7.1 million, and the top rate is 16 percent, applying to the taxable estate over $10.1 million (source: Minnesota House Research Department, November 2025; Minn. Stat. § 291.03, subd. 1; Minnesota Department of Revenue estate-tax-rates page).
The tax applies only to the amount above the exclusion, not the whole estate. But 13 to 16 percent on the excess is real money. On an estate a few hundred thousand dollars over the line, the bill can run into the tens of thousands — money that comes out of what your family inherits.
No portability — a Minnesota-specific trap for married couples
This is the point that costs married couples the most, and it is worth reading twice.
Under the federal system, spouses get “portability”: when the first spouse dies without using all of their exemption, the survivor can carry the unused portion forward, effectively stacking both exemptions. Minnesota does not do this. As the Minnesota Department of Revenue put it in a January 2025 legislative analysis, “Portability is currently not available under Minnesota law.” (Source: Minnesota Department of Revenue, Analysis of S.F. 30, January 22, 2025.)
Here’s why that matters in practice. Many married couples own everything jointly and leave everything to each other. When the first spouse dies, the transfer to the survivor is generally tax-free because of the marital deduction — so far so good. But that first spouse’s $3 million exclusion goes unused and disappears. When the second spouse later dies owning the couple’s combined assets, only one $3 million exclusion is left to shield the whole estate.
Without planning, then, a Minnesota couple can effectively lose one spouse’s $3 million exclusion — exposing a much larger slice of their combined estate to tax at the second death. This is one of the most fixable problems in estate planning, and we’ll come back to the common fix (a credit-shelter or bypass trust) below. But you cannot assume the federal “portability” rule bails you out in Minnesota. It doesn’t.
The three-year gift add-back: no deathbed workaround
A natural instinct is to give assets away near the end of life to get under the threshold. Minnesota anticipates that.
Minnesota has no separate gift tax — the Legislature enacted one in 2013 and repealed it in 2014. But it kept a three-year rule: certain taxable gifts made within three years of death are added back into the Minnesota taxable estate (source: Minn. Stat. § 291.016, subd. 2; Minnesota House Research Department, November 2025). The add-back applies to gifts that would be subject to the federal gift tax — that is, gifts above the annual per-recipient exclusion, which is $19,000 for 2025 (source: Minnesota House Research Department, November 2025).
The practical takeaway: large deathbed gifting is not a reliable last-minute escape hatch in Minnesota. Ordinary annual gifting within the exclusion, made well in advance, is a different matter — but that is a strategy to design with an advisor over time.
Family farms and small businesses: a special exclusion, with strings
Minnesota recognizes that a family farm or a closely held business can be worth a lot on paper while producing modest income — and that forcing a sale to pay estate tax defeats the point of a family enterprise. So the law allows two additional exclusions: qualified small business property and qualified farm property (source: Minn. Stat. § 291.03, subds. 9 and 10; Minnesota Department of Revenue, 2025 Form M706 instructions).
For 2025, the maximum qualified small-business/farm deduction is $2,000,000, and the combined total of that deduction plus the general $3,000,000 exclusion cannot exceed $5,000,000 (source: Minnesota Department of Revenue, 2025 Form M706 instructions; Minnesota House Research Department, November 2025).
The conditions are strict, and this is very much a “talk to a professional” area. In general terms, the property must have been owned by the decedent or spouse for three years before death, there are material-participation and use requirements, and the heirs must continue to own and use the property (farmland must stay classified as agricultural) for three years after death. Fall short, and a recapture tax equal to 16 percent of the excluded value can be imposed (source: Minn. Stat. § 291.03, subd. 11; Minnesota House Research Department, November 2025). The exclusion is valuable but not automatic — get the qualification and continued-use rules reviewed carefully.
Own Minnesota property but live elsewhere? You can still be reached
The Minnesota estate tax is not only for Minnesota residents. If a nonresident dies owning real property or tangible personal property with situs in Minnesota — a lake cabin, farmland, or similar — that Minnesota-situated property can be pulled into the Minnesota estate tax when the estate’s total (including federal adjusted taxable gifts within three years) exceeds the threshold (source: Minnesota Department of Revenue, 2025 Form M706 instructions). Interests held through certain pass-through entities that own Minnesota property can raise the same issue. If you split time between states, this is worth a specific conversation with counsel.
How trusts and planning address the trap
Now the constructive half. None of the following is a recommendation for your situation — the right tool depends entirely on your facts, and choosing among them requires an estate planning attorney working alongside a tax advisor. But here is the general landscape, so the vocabulary isn’t a mystery.
Credit-shelter (bypass) trusts — the fix for no portability
This is the classic answer to Minnesota’s no-portability trap. Instead of leaving everything outright to the surviving spouse, the first spouse’s estate funds a credit-shelter trust (also called a bypass trust) up to the exclusion amount. The surviving spouse can still benefit from the trust — typically income, and access to principal under defined standards — but the trust assets are structured to stay out of the survivor’s taxable estate at the second death. The result: both spouses’ exclusions are used rather than one being wasted. For couples whose combined estate is near or over $3 million, this is often the single most important move.
Irrevocable life insurance trusts (ILITs) — getting the death benefit out
Remember that life insurance proceeds are included in your taxable estate if you own the policy. An irrevocable life insurance trust is designed so the trust — not you — owns the policy, so the death benefit can pass outside your taxable estate. For families whose estate is over the line largely because of a big life-insurance number, this can be a meaningful tool. It has to be set up carefully and in advance.
Revocable living trusts — useful, but they do NOT reduce estate tax
This is an important myth to correct. A revocable living trust is a common and useful tool — it can help your estate avoid probate and keep administration private. But because you keep control of the assets and can revoke the trust at any time, those assets are still part of your taxable estate. A revocable living trust, standing alone, does not reduce Minnesota estate tax. If someone told you “I have a living trust, so I’m covered,” that’s worth a second look.
Lifetime gifting and charitable strategies
Structured gifting over time (within the annual exclusion, and mindful of the three-year add-back) can gradually reduce the taxable estate. Charitable giving — outright bequests, charitable trusts, and similar vehicles — can reduce the taxable estate while supporting causes that matter to a family. These are long-game strategies, best designed with professional guidance.
A practical, non-alarmist close
You don’t need to panic, but you should do the arithmetic. Add up the likely value of your estate: home equity + retirement accounts + life insurance you own + business or farm value + investment and bank accounts. If that total is anywhere near $3 million, Minnesota’s estate tax is worth a serious conversation.
A few reminders:
- Married couples especially: do not assume portability. Minnesota doesn’t have it. Without planning, one spouse’s exclusion can simply vanish.
- A living trust is not a tax shield. It helps with probate, not the estate tax.
- Revisit after major changes — a big jump in home or business value, a large life-insurance policy, an inheritance, a move into or out of Minnesota, or a change in the law (the exclusion and exemption figures do change).
- Plan while it’s a planning question, not an estate-administration problem for your grieving family. The tools that work — credit-shelter trusts, ILITs, structured gifting — generally have to be in place before death, not arranged after.
If you’re a Minnesota homeowner, retiree, small-business owner, or farm family who has never really looked at this, that is exactly the point of writing it down. The trap catches the people who assume it doesn’t apply to them. A short conversation with an estate planning attorney and a tax advisor is a small price to find out where you stand.
