Minnesota PTET Election 2026: How the Pass-Through Entity Tax Works After the Extension
Minnesota almost let its pass-through entity tax die. It was set to expire after 2025, sat in limbo through the first quarter of 2026, and then came back to life on May 27, 2026. Now it runs through 2027, at a flat 9.85%, and for a lot of Minnesota S-Corp owners it is the only state-tax deduction the federal SALT cap still allows.
Picture a Minneapolis architecture firm run as an S-Corp, owned by two spouses, throwing off $400,000 of Minnesota income. The couple files jointly with about $650,000 of income, so the federal SALT cap has already ground down to the $10,000 floor and their property tax alone eats it. Every dollar of Minnesota income tax on that $400,000 is nondeductible on their federal return unless the business pays it instead of them. That is what the pass-through entity tax does, and in Minnesota it nearly went away this year. The owners below are theoretical, not actual EntityIQ clients, but the whipsaw over the election was real.
The election almost expired, then got extended to 2027
Minnesota enacted its PTE tax in 2021 for tax years beginning after December 31, 2020, with a sunset that would have ended it after the 2025 tax year. That expiration took effect at the start of 2026, and for several months there was no election on the books. On May 27, 2026, Governor Tim Walz signed HF3127, which reinstated the tax retroactively to January 1, 2026, and pushed the sunset out to December 31, 2027. So the election is available again for 2026 and 2027, then scheduled to lapse unless the Legislature acts once more.
Because the fix arrived in late May, after the April 15 first-quarter estimated payment date, the legislation provides transition relief. A first-quarter 2026 estimated PTE payment is treated as timely if it was made by the second-quarter due date, which is June 15, 2026, for a calendar-year entity. If you skipped the first-quarter payment while the law was dead, that relief is what keeps you from owing an underpayment penalty on it.
What the Minnesota PTE tax is
The mechanics are set out in Minnesota Statutes section 289A.08, subdivision 7a. A qualifying entity elects to pay Minnesota income tax at the entity level on the qualifying owners' shares of income, and each owner then claims a credit for their share of that tax. The rate is a flat 9.85%, which is Minnesota's top individual rate under section 290.06. There is no graduated schedule at the entity level, so even an owner whose own marginal rate would be lower is prepaying at the top rate and recovering the difference through the credit.
The credit is refundable and equals 100% of the owner's share of the tax the entity paid, so for a Minnesota resident it offsets the state tax they would otherwise owe on the same income. The election does not add state tax, it just moves where the tax is paid. For certain nonresident owners, the Schedule PTE can also satisfy their Minnesota filing requirement, much like a composite return.
Who qualifies, and who does not
A qualifying entity is a partnership, an S corporation, or an LLC taxed as a partnership or S corporation. A single-member LLC that is disregarded for federal purposes does not qualify, because there is no separate entity-level income or K-1 to work with. An LLC that has elected C corporation treatment does not qualify either, since it already pays its own corporate tax.
On the owner side, the qualifying owners are individuals, estates, and certain trusts. An interest held through a corporate parent or another partnership is not a qualifying owner, and the income attributable to those owners is left out of the PTE tax base. The election is made by qualifying owners who together hold more than 50% of the ownership interest held by qualifying owners, and once a majority makes it, the election binds every qualifying owner of the entity for that year.
How you actually make the election
You make the election by completing Schedule PTE and attaching it to the entity's Minnesota return, Form M8 for an S corporation or Form M3 for a partnership. It must be filed by the due date of that return, including any extension, so a calendar-year entity that extends has until September 15 to decide. The election is irrevocable once made, which makes it a year-end call, not a hedge you can unwind if the numbers change.
The entity also makes quarterly estimated PTE payments in four equal installments on the standard April, June, September, and January schedule, and Minnesota charges underpayment interest if you come up short. The transition relief above covers the first-quarter 2026 payment.
The 2026 SALT-cap math, in one picture
The reason any of this matters is the federal deduction. The One Big Beautiful Bill Act, signed July 4, 2025, raised the itemized SALT deduction cap under IRC section 164(b)(6) to $40,400 for 2026, but that larger cap phases out above $505,000 of modified adjusted gross income. Above that line the cap drops by 30% of the excess and floors at $10,000, which it reaches around $606,333 of MAGI. Our theoretical couple at $650,000 is already back to the $10,000 floor, so their Minnesota income tax buys them no federal deduction on Schedule A at all.
The PTE tax runs on a different track. It is paid by the business and deducted against business income under the reasoning of IRS Notice 2020-75, before the profit ever flows to the owners' 1040. It is not an itemized deduction, so the SALT cap and its phaseout never touch it. Here is the same $400,000 of Minnesota income, taxed the two different ways, at an assumed 35% federal marginal rate.

Where the state income tax gets deducted
Without the election
Property tax already fills the $10,000 cap. The income tax is nondeductible.
With the PTET election
$39,400 deducted before the K-1, at a 35% rate. No extra Minnesota cost.
Figures are 2026 and rounded. The $13,790 is the federal deduction value only ($39,400 × 35%); the state credit makes the owner whole for the Minnesota tax the entity paid. Actual results depend on your bracket, residency, and other income.
The swing is $13,790 a year on one election, and the only variable that moves it is whether the Minnesota tax sits on the business return or on the couple's Schedule A. For an owner whose MAGI has phased the personal cap down to $10,000, the entity-level deduction is often the only way left to write off state income tax on business profits.
Where the election can backfire
The PTE tax is not automatically a win. A part-year owner, a nonresident, a trust, or an owner with large Minnesota credits can end up with the entity paying at the flat 9.85% top rate when the owner's own rate would have been lower, and the refundable credit still has to clear on the individual return for the money to come back. The election also binds every qualifying owner once a majority elects, so someone who would rather not participate has no say.
And remember the sunset. The extension runs only through December 31, 2027, and unless the Legislature renews it again the election disappears after that, so do not build a multi-year plan around it. If your total state and local taxes already fit under the $40,400 cap and your MAGI sits below $505,000, the personal deduction may capture everything anyway, and a PTE election just adds an entity filing for no federal gain.
If you run a Minnesota S-Corp, run the numbers before you elect. The EntityIQ S-Corp tax calculator models the wage base and the QBI deduction, and you can pair it with our guides on whether the PTET still beats the SALT cap and the PTET deduction workaround for the federal side.

Minnesota's PTE tax carries a 2027 sunset and detailed qualifying-owner rules, so confirm the current statute and consult a qualified Minnesota CPA before you file the election.
