New York PTET Election 2026: How to Opt In Before the March 15 Deadline

A New York consulting firm organized as an S-corp calls me every February with the same worry. The owners keep hearing they are leaving money on the table by not electing the pass-through entity tax, and they want to know if it is too late to fix it for last year. It usually is. The pass-through entity tax, or PTET, is one of the few tax moves you have to commit to before the year is over, not when you file. The owner in the example below is theoretical, not an actual EntityIQ client, but the deadline and the math are real.

What the PTET actually does

Since 2018, individuals have been capped on how much state and local tax they can deduct on a federal Schedule A. The cap sat at $10,000 for years under IRC §164(b)(6). The One Big Beautiful Bill Act raised it to $40,400 for 2026, but that higher cap phases back down once modified adjusted gross income passes $505,000, and it reverts to $10,000 in 2030. For a New York business owner paying a state tax rate near 10%, that cap leaves a lot of otherwise deductible tax stranded.

The PTET is the workaround. Instead of the owner paying New York income tax personally, where the SALT cap chokes the deduction, the business itself pays an entity-level tax that is fully deductible as an ordinary business expense on the federal return, outside the individual cap entirely. The IRS blessed this structure in Notice 2020-75. New York built its version into Tax Law Article 24-A in 2021. The owner then claims a credit on the personal return for the tax the entity paid, so the state tax is never paid twice. What changes is only where the deduction lands.

The March 15 deadline that trips everyone up

Here is the part people get wrong. New York's PTET election for the 2026 tax year is due by 11:59 p.m. Eastern on March 15, 2026, and the state does not grant extensions. The election is annual, so it must be made every year the entity wants in, and it is made through the entity's own New York State Online Services account. This is not the return deadline. You elect for 2026 by March 15, 2026, months before you know your final numbers, and once the election is made it is irrevocable for that year.

I stress this because the New York State Department of Taxation and Finance has been unforgiving about it. A missed election is a missed year, full stop. If you think you might want in, opt in early in the year and sort out the exact dollars later. There is no downside to electing and then having a small year, but there is a large downside to waiting.

The rates, and the separate New York City tax

The New York State PTET uses graduated rates on the entity's pass-through taxable income: 6.85% up to $2 million, 9.65% from $2 million to $5 million, 10.30% from $5 million to $25 million, and 10.90% above $25 million. These are the same top brackets that would apply to a high-earning individual, so for most owners the entity-level tax is close to what they would have paid personally, just moved to a place where it is fully deductible on the federal return.

New York City has its own pass-through entity tax at a flat 3.876%, which is the top New York City personal income tax rate. It only reaches the share of income allocated to New York City resident owners, it has its own election that is also due March 15, and an entity must already be opted into the state PTET to make the city election. A New York City resident owner therefore stacks the state PTET and the city PTET, and both are deductible at the federal level.

How the money moves

Follow the theoretical owner above, a single New York City resident whose S-corp allocates $1,000,000 of income to her. Without the election, she pays roughly $107,260 in combined state and city income tax on her Form IT-201, but her federal SALT deduction is stuck near the cap, so only a sliver of that tax reduces her federal bill. Elect the PTET, and the entity writes the same check. That $107,260 now sits on the S-corp's federal return as a deduction, cutting the income on her K-1. At a 37% federal marginal rate that deduction is worth about $39,686, and after subtracting the small SALT deduction she would have gotten anyway, the election nets her close to $36,000 in federal tax she keeps. She is not out of pocket in New York either, because she claims the full $107,260 as a credit. The numbers are illustrative 2026 figures and are rounded.

Estimated payments and claiming the credit

Electing is step one. New York also wants the money during the year. An electing entity must make estimated PTET payments on or before March 15, June 15, September 15, and December 15, with each installment at least 25% of the required annual payment, which is the lesser of 90% of the current year's PTET or 100% of the prior year's PTET. A New York City election carries its own parallel estimated payments. Underfunding the account can cost you the deduction timing you were chasing, so fund it as you go.

At filing, each owner claims a refundable New York State PTET credit on Form IT-653, filed with the individual return, equal to their share of the PTET the entity paid. Because the entity already deducted that tax federally, New York requires the same owner to add the credit amount back to New York income as an addition modification on Form IT-225, so the tax is not counted twice. The net effect is that the state tax gets paid once, at the entity, and the owner keeps the federal deduction.

Is it still worth it in 2026?

It depends on your income and your total state taxes. The One Big Beautiful Bill Act raised the SALT deduction cap to $40,400 for 2026, so an owner whose combined state and local taxes stay under that ceiling and whose modified adjusted gross income is below $505,000 may already capture most of the benefit on Schedule A without electing. The PTET still wins clearly for high earners in the phasedown zone above $505,000 of MAGI, for New York City residents stacking city and state tax, and for anyone whose property and income taxes already run past $40,400. If you are a New York S-corp or partnership with meaningful profit, the PTET is usually the single largest federal deduction available to you, and it costs nothing but a March 15 election and some estimated payments.

If you are still deciding whether the S-corp election itself makes sense before you layer the PTET on top, run your self-employment tax numbers first with the EntityIQ S-Corp tax calculator.
