For most owners of profitable S-corporations, LLCs, and partnerships, the federal SALT (State and Local Tax) cap has been one of the most expensive tax-law changes of the last decade. The Tax Cuts and Jobs Act capped the itemized deduction for state and local taxes at $10,000 — a number so low that a single property-tax bill on a Florida medical building or a New York condo can blow through it before state income tax even enters the picture. The One Big Beautiful Bill Act raised that cap to $40,000 for 2025 through 2029, but the increased cap phases out for taxpayers above $500,000 of modified AGI and reverts to $10,000 in 2030. For the high-earning owner — the exact taxpayer who pays the most state income tax — the cap is still very much a problem.
Quietly, in the years since 2018, 36 states have enacted a tax workaround that legally moves the deduction off the owner's personal return and onto the business return, where the SALT cap does not apply. The IRS blessed the workaround in Notice 2020-75, and the savings have become hard to ignore. The mechanism has a clunky name — the Pass-Through Entity Tax, or PTET — and in 2026 it remains one of the highest-ROI tax elections small business owners routinely overlook.
At Numbers Right, our tax strategy team models PTET elections for clients in every state that has enacted one. This guide explains what the PTET actually is, how it saves federal tax in practice, the deadline traps that quietly disqualify owners every year, and how to tell whether it makes sense for your business in 2026.
The SALT Cap Problem in One Paragraph
If your individual state and local tax bill exceeds the federal SALT cap, the dollars above the cap are no longer deductible on your federal Schedule A. For a New York or California business owner earning $500,000 in pass-through income, that easily means $40,000 to $60,000 of state income tax becomes non-deductible at the federal level — costing the owner $14,000 to $22,000 in extra federal tax every year. PTET is designed to make that problem go away by recharacterizing the same payment as a business deduction.
How a Pass-Through Entity Tax Election Actually Works
The mechanic is elegant once you see it. In a state with a PTET regime, the business itself elects to pay state income tax at the entity level, instead of letting the income flow through to the owner and be taxed on the owner's personal return.
The federal effects of that single change are dramatic:
- The state tax payment becomes an ordinary business expense on the entity's federal Form 1120-S or 1065 — fully deductible, no SALT cap.
- The pass-through income flowing to the owner is reduced by the amount of state tax paid at the entity level.
- The owner typically receives a state-level credit equal (or nearly equal) to their share of the PTET, so the state does not collect the tax twice.
Net result: the owner ends up paying the same state tax they were always going to pay — but it now produces a federal deduction it could not produce before. The SALT cap, as a practical matter, disappears for the portion of state tax tied to pass-through income.
A 2026 Example: $11,000 of Federal Savings on a Single Election
Consider Dr. Ramirez, a New York S-Corp specialist paying herself a $250,000 W-2 salary and taking $400,000 in distributions, for $650,000 of total income from the practice.
Without PTET vs. With PTET — Dr. Ramirez's 2026 Federal Return
| Item | Without PTET | With PTET |
|---|---|---|
| NY state tax on $400K distribution (~6.85%) | $27,400 | $27,400 (paid by S-Corp) |
| Federal deduction for that state tax | $0 (above SALT cap) | $27,400 (business expense) |
| Federal tax saved (~37% bracket + 3.8% NIIT) | $0 | $11,100–$11,700 |
| QBI & AMT interaction | — | Modeled separately |
For multi-owner firms, multi-state practices, and partnerships with several high-earning principals, the federal savings climb quickly into the high five and even six figures every year.
Which States Have a PTET — and Which Do Not
As of 2026, 36 states and New York City have enacted a PTET regime. Florida, Texas, Nevada, Wyoming, South Dakota, Tennessee, and Washington either have no individual income tax to deduct or have not adopted an entity-level PTET. For multi-state owners, that matters: PTET planning is state-by-state, not a single national election. A medical group operating in New Jersey, New York, and Connecticut has to elect — and pay — in each state separately, on three different timelines, with three different sets of forms.
The Six Deadline and Election Traps That Disqualify Owners Every Year
Most missed PTET savings are not the result of a bad strategy. They are the result of a missed mechanical step. The most common errors:
Where PTET Elections Quietly Fail
- Missing the annual election deadline. Many states require the election by March 15 of the tax year — not after year-end, when most owners think about tax planning.
- Missing the estimated payment requirement. Some states (notably New York) require the entity to make a specific tax payment by a specific date to lock in the election.
- Failing to elect in every applicable state. A multi-state business may be eligible in four or five states and lose the deduction in any state where it does not affirmatively elect.
- Mismatched tax years. The PTET election typically must match the entity's federal tax year, not a calendar year — an easy trap for fiscal-year entities.
- Missing owner consents. Some states require all owners to agree to the election in writing; one dissenter can invalidate it for everyone.
- Forgetting the personal credit. Owners who fail to claim the offsetting state credit on their personal return effectively pay the same tax twice.
A CFO advisor with multi-state PTET experience usually pays for themselves many times over just by managing the deadline calendar.
When PTET Does Not Make Sense
PTET is not universally beneficial. Specific situations where the election can backfire or produce no measurable savings include:
- Owners already under the SALT cap because their pass-through income is modest.
- Owners in non-conforming states where the state offers only a partial credit for PTET paid.
- Loss years where the income would be more valuable carried forward as a personal NOL.
- Owners with passive partners or non-resident owners whose state-credit mechanics are unfavorable.
- Owners fully under the temporary $40,000 SALT cap who can capture the deduction personally without complication.
A proper PTET analysis runs the numbers both ways — at the entity level and at the owner level — and accounts for AMT, QBI, state-tax interactions, and any non-resident owner exposure. This is not a one-button election.
How PTET Interacts With the Rest of Your 2026 Tax Plan
PTET decisions do not live in isolation. They should be modeled alongside the other major levers of small business tax planning in 2026:
- Reasonable compensation: An S-corp owner's W-2 wages are not PTET-eligible — only K-1 income is. Adjusting the salary-to-distribution split changes how much PTET is on the table.
- QBI (Section 199A) deduction: PTET reduces pass-through income, which can shrink the QBI deduction. The federal savings usually outweigh that drag, but it has to be modeled.
- Section 179 and bonus depreciation: Heavy depreciation in a given year can drive taxable pass-through income to near zero, which reduces the value of a PTET election in that year.
- Multi-state apportionment: Practices with patients or clients in multiple states need their state apportionment percentages right before PTET savings can be projected accurately.
For medical practices in particular, our medical practice finance team models PTET against W-2 wage thresholds, QBI phase-outs, and the doctor's personal AMT exposure to find the optimal combined strategy. The right conversation is rarely "PTET yes or no." It is "PTET at what salary, with what depreciation timing, in which states."
Run the Numbers Before Your Next State Deadline
If you operate a profitable S-corp, LLC, or partnership in any state with income tax, a PTET election is almost certainly worth modeling for 2026. The election deadlines are state-specific and unforgiving — miss the window and the savings are gone for the year. The right time to run the analysis is mid-year, while there is still time to adjust owner salary, schedule the entity-level estimated payments, and collect owner consents.
Wondering whether a Pass-Through Entity Tax election would save your business federal tax in 2026 — and whether you have already missed any of this year's elections? Schedule a free PTET analysis and our tax strategy team will run the numbers state by state, model the interaction with your QBI deduction and reasonable compensation, and lock in the election in every state where it makes financial sense.
