In Parts 1 and 2 of this series, we talked about gifting on the federal level — where the exemption is a generous $15 million per person. Here in Minnesota, though, there’s a second, much smaller umbrella to think about, and it catches a lot more families than the federal one does. 

Minnesota has its own estate tax, separate from the federal system, with an exemption of just $3 million per person in 2026 — a number that has stayed flat for several years now. If your estate is worth more than that when you pass away, the excess is taxed at rates ranging from 13% to 16%. For a family whose net worth includes a home, investment accounts, retirement accounts, and perhaps a business or a lake property, $3 million can arrive sooner than expected. 

No Gift Tax, But Not No Rules 

Let’s start with the good news: Minnesota does not have its own gift tax. It was repealed years ago. So when you make a gift during your lifetime, you don’t owe Minnesota tax on the gift itself. 

But, and this is the part people miss, Minnesota does have a rule that reaches back and asks about gifts you made shortly before you died. Think of it less like a tax on giving, and more like a rearview mirror the state checks once, at the very end. 

The Three-Year Lookback: How the Rearview Mirror Works 

If you make a taxable gift, meaning a gift larger than the federal annual exclusion of $19,000 per recipient, within three years of your death, Minnesota adds that gift back into your taxable estate when calculating whether you owe Minnesota estate tax. 

A few things worth knowing about how this actually works: 

The purpose of this rule is simple: it discourages “deathbed gifting” = moving assets out the door at the last minute purely to dodge the Minnesota threshold. It’s not a reason to avoid gifting. It’s a reason to start early. A gifting plan that unfolds over many years, well ahead of any three-year window, remains one of the most effective ways to bring an estate below $3 million. 

No Portability Between Spouses. The “Use It or Lose It” Rule 

Here’s where Minnesota differs sharply from the federal system, and where I see the most missed planning opportunities. At the federal level, a surviving spouse can typically inherit whatever estate tax exemption their late spouse didn’t use. Minnesota does not allow this. 

Each spouse has their own $3 million exemption, and if the first spouse to pass away doesn’t use it, it simply disappears. It does not carry over to the survivor. Picture two separate umbrellas, one per spouse. If you don’t open your umbrella before you leave, your spouse doesn’t get to use it later; it stays closed forever. 

For married couples with combined assets above $3 million, this is exactly why we often recommend a credit shelter (or “bypass”) trust as part of an estate plan. Structured properly, this kind of trust captures the first spouse’s exemption at their passing instead of letting it go unused, which can shelter up to an additional $3 million from Minnesota estate tax when the surviving spouse later passes. 

A Bigger Umbrella for Business Owners and Farm Families 

If you own a qualifying small business or farm operation, Minnesota offers an additional deduction of up to $2 million on top of the standard $3 million exemption — potentially sheltering as much as $5 million for a family whose wealth is concentrated in the operating business or farmland, rather than liquid investments. 

This deduction has real strings attached: it generally requires the owner to have materially participated in the business, and there are limits tied to the size of the operation. It’s a valuable tool for succession planning, but it needs to be set up correctly well before it’s needed. This is not something to discover the hard way. 

Filing Requirements 

One quirk worth flagging for families who assume “no federal filing” means “nothing to file”: because the Minnesota exemption is so much lower than the federal $15 million exemption, it’s entirely possible to owe Minnesota estate tax, and be required to file a Minnesota Form M706, with no federal estate tax return required at all. The two systems run on separate tracks. 

What This Means for Your Planning 

None of this is meant to alarm you. It’s meant to help you plan with clear eyes. A few takeaways I share with clients: 

The Takeaway 

Minnesota’s estate tax catches far more families than the federal system does, simply because the exemption is so much smaller. The rules aren’t meant to punish generosity, they’re meant to prevent last-minute maneuvering. With early, thoughtful gifting and the right trust structures, most families can plan their way to a much smaller, or nonexistent, Minnesota estate tax bill. 

If you’d like to see where your estate stands against the $3 million threshold, or want to talk through a trust structure that preserves both spouses’ exemptions, I’d love to help you take a look.
