Minnesota PTET: The Election May End, But Planning Doesn’t Have To

Minnesota’s current legislative session is now underway, and one issue with meaningful implications for closely held businesses and their owners is the future of the state’s pass-through entity tax (PTET).

While the mechanics of the PTET can be complex, its purpose is simple: to help business owners of pass-through entities, such as S corporations and partnerships, mitigate the federal limitation on deducting state and local taxes (SALT).

Learn why federal SALT rules still shape the PTET conversation — and how legislative uncertainty could affect planning, estimates, and multistate choices sooner than expected.

Why federal SALT rules still drive PTET decisions

Since 2018, individuals (and trusts) have generally been limited to deducting no more than $10,000 of SALT on their federal income tax returns. In response, many states, including Minnesota, enacted PTET regimes allowing partnerships and S corporations to pay state income tax at the entity level.

Because that tax is paid by the business rather than the individual owner, it’s generally deductible for federal purposes without being subject to the $10,000 cap.

Minnesota adopted its PTET beginning in 2021, after the IRS confirmed these entity-level taxes would be respected for federal tax purposes. Since then, many Minnesota pass-through entities and their owners have realized meaningful federal tax savings by making the election.

From the outset, however, Minnesota’s PTET wasn’t designed to be permanent. It was tied to the expected expiration of the federal deduction limitation, which under the original federal law was scheduled to sunset after 2025.

What changed – and why the PTET may have expired

Congress recently revisited the federal deduction limitation and chose not only to extend it, but to increase it temporarily. Under the new federal legislation, the SALT limitation cap. rises to $40,000 through 2029 before reverting to $10,000 in 2030. Given that extension, many business owners assumed Minnesota’s PTET would continue as well.

The complication lies in how Minnesota conforms to federal tax law. Minnesota is a “static conformity” state, meaning it doesn’t automatically adopt federal tax changes as they occur. Instead, the state tax code reflects federal law only through a specific conformity date, which is currently May 1, 2023.

As a result, Minnesota law still reflects the earlier federal framework that assumed the deduction limitation would expire after 2025.

To say it differently, Minnesota adopts the Tax Cuts and Jobs Act’s 2025 SALT limitation expiration date (incorporated in the 2023 Internal Revenue Code) and not the One Big Beautiful Bill Act’s SALT limitation extension (incorporated in the 2025 Internal Revenue Code).

Because of that disconnect, the Minnesota Department of Revenue has taken the position that Minnesota’s PTET expired on December 31, 2025. Unless the legislature updates the state’s conformity date or enacts separate legislation extending the PTET, calendar year partnerships and S corporations will not be able to make a Minnesota PTET election for 2026 and later years.

Multistate businesses may face added PTET risk

This potential expiration carries a related consequence particularly important for multistate businesses. When Minnesota enacted its PTET, it also allowed Minnesota residents to claim a credit for PTET paid to other states. That credit helped mitigate double taxation when a business operated across state lines.

If Minnesota’s PTET regime isn’t extended, that credit would also disappear beginning with 2026 returns, potentially changing the economics of PTET elections made in other states.

Timing challenges: Elections, estimates, and open questions

As the Minnesota legislative session is just getting underway, the timing of any action remains uncertain. While a Minnesota PTET election for 2026 wouldn’t be made until returns are filed in 2027, estimated tax payment obligations arise much sooner.

If the PTET isn’t extended, owners may need to shift back to making individual estimated payments on their share of Minnesota income rather than relying on entity-level payments. That transition could be especially disruptive if clarity doesn’t come until well into 2026.

The uncertainty is magnified for pass-through businesses operating in multiple states. Some states require early action to preserve a PTET election, even though the ultimate tax return won’t be filed until the following year (New York is an example).

At the same time, if Minnesota no longer provides a credit for PTET paid to other states, the decision to make those elections becomes less automatic and more dependent on each owner’s federal tax profile and overall state tax exposure.

As lawmakers consider whether to extend Minnesota’s PTET and the related credit, they’ll inevitably weigh revenue concerns against taxpayer impact.

Several neighboring states, including Iowa and Wisconsin, recognize extended PTET regimes, providing meaningful federal tax relief to residents. Whether Minnesota follows that path remains to be seen.

Focus your tax planning efforts

Regardless of how the legislature ultimately acts, the current uncertainty presents an opportunity for pass-through entities and their owners to revisit assumptions that may have gone unchallenged since the PTET was first enacted.

In an environment where timing and conformity matter as much as the underlying tax rates, thoughtful planning — not reactive decision making — is key to avoiding surprises and preserving flexibility.

Owners may want to consider a few core tax planning areas as they look ahead:

• Revisit income projections for 2026 and beyond
• Review ownership profiles carefully
• Map multistate exposure
• Pressure‑test existing assumptions
• Model timing scenarios
• Coordinate tax planning with broader business goals
• Document decision points and trigger events

Business voices matter in the PTET debate

This issue presents a meaningful opportunity for business owners and their advisors to engage in constructive dialogue with policymakers.

Because Minnesota’s PTET has generally been viewed as revenue neutral while delivering tangible federal tax relief to Minnesota residents (and nonresidents), legislators may benefit from hearing how the potential expiration affects closely held businesses, multistate operations, and individual taxpayers.

Thoughtful legislative advocacy — particularly when grounded in real-world business impact rather than technical tax theory — can play an important role as lawmakers consider whether to extend the PTET regime and the related credit.

Together with proactive tax planning, informed engagement can help pass-through businesses not only prepare for multiple outcomes, but also have a voice in shaping the one that ultimately prevails.
