PTE Election Strategy 2026: A State-by-State Look at What’s New

The pass-through entity tax election has quietly become one of the most valuable state tax strategies available to S corporation owners, and 2026 has brought a wave of changes worth tracking. More than 30 states plus New York City now offer some form of PTE election, and several — led by Massachusetts — have updated their rules over the past year in ways that directly affect S-corp tax strategy for owners in high-tax states. Whether you already elect PTE treatment or have never looked into it, this is a good year to check where your state stands.

A Quick Refresher on Why the PTE Election Exists

The PTE election was created as a workaround to the SALT cap — the federal limit on how much state and local tax an individual can deduct on their personal return. Rather than paying state income tax personally and running into that ceiling, S corporation owners in PTE states can have the business pay the tax at the entity level instead. Under IRS Notice 2020-75, the S-corp deducts the payment as an ordinary business expense with no cap, and the shareholder typically receives a state tax credit that offsets what they would have owed personally. For S-corp owners in high-tax states, this single election often represents the single largest available piece of S-corp tax strategy each year. For the math on when the election beats simply deducting under the higher cap, see our SALT cap vs. PTET comparison.

Whether the workaround remains valuable depends on the federal SALT cap itself. The OBBBA raised the cap under Section 164(b)(6) from $10,000 to $40,000 for 2025, rising to $40,400 for 2026 and increasing 1% annually through 2029 before reverting to $10,000 in 2030. Earlier drafts of the OBBBA would have restricted PTE deductibility for specified service businesses like law, accounting, and consulting firms — but that restriction was dropped, and the law as enacted contains no PTET limitation. The PTE election survived intact for every pass-through entity, S-corps included, which is why state-level PTE activity has continued to accelerate rather than wind down.

Massachusetts Adds a 9% Combined Option for 2026

Massachusetts has offered its standard PTE excise — Chapter 63D, at 5% — since 2021. For tax years beginning January 1, 2026, new legislation created Chapter 63E, a second elective excise that allows eligible S corporations to pay an additional 4% on qualifying income above the state’s individual income surtax threshold ($1,107,750 for 2026). An S-corp can elect Chapter 63D, Chapter 63E, or both — meaning eligible high-income owners can now elect into a combined 9% PTE rate rather than being capped at the original 5%.

The mechanics matter here. The 9% figure is not a flat tax on every dollar of S-corp income — the 4% Chapter 63E layer only applies to income above the surtax threshold. Both elections are made at the entity level using the unified Form 63-ELT, are due with the S-corp’s return by its due date including valid extensions, and are irrevocable for the year once made. Massachusetts S-corp owners should also know that both PTE excises expire if the federal SALT deduction limitation expires or is repealed — the state built the elections to end alongside the federal cap they exist to work around. If you file in Massachusetts, this pairs with the state’s broader response to the federal law — see our guide to Massachusetts OBBBA decoupling.

What’s Changed in Other States This Year

Massachusetts is not the only state that has moved on PTE rules over the past year. Several states extended or made permanent PTE programs that had sunset dates approaching. Illinois removed its PTE tax sunset date entirely under Public Act 104-0453, making the election permanent. Oregon extended its PTE election through tax years beginning before January 1, 2028. Minnesota extended its election through the same date, retroactive to the start of 2026 — but note that for 2026 Minnesota requires four equal, on-time estimated payments, and calendar-year entities must elect by the extended return due date of September 15, 2026, with no late elections accepted.

California made its own significant update: the state’s PTE elective tax, a flat 9.3% rate, was extended through 2030, and the state relaxed its notoriously strict June 15 prepayment deadline. Previously, missing that payment invalidated the entire election for the year — now, for tax years 2026 through 2030, a late or partial payment only reduces the owner’s credit by 12.5% of the shortfall rather than voiding the election outright. Michigan pushed its PTE election deadline out to the last day of the ninth month following year-end, giving S-corp owners far more time to decide with complete financial data in hand rather than guessing in the first quarter.

What This Means for Your S-Corp

If your S corporation operates in a state with a PTE election and you have not reviewed your eligibility in the past year, that review belongs on your calendar before your next filing deadline. State rules are not static — rates, deadlines, and eligibility have all shifted meaningfully across multiple states in just the past six months, and an election made under last year’s assumptions may no longer reflect the best available option.

This is also an area where clean bookkeeping pays for itself. PTE elections require accurate entity-level income calculations tied to shareholder K-1s, and errors here can affect both your state credit and your federal deduction. A CPA firm that specializes in S-corp accounting can model whether electing in — or electing into an enhanced option like Massachusetts’ new Chapter 63E — actually improves your specific tax position, since the benefit depends heavily on individual shareholder income, residency, and how close each owner is to the federal SALT cap’s phase-out threshold. Good accounting for small business here is less about compliance and more about making sure you are not leaving a real state tax benefit unclaimed.
