Pass-Through Entity Tax (PTET) Elections: The State Tax Workaround for Business Owners

The federal cap on the individual deduction for state and local taxes, introduced in 2017, made state income tax on business profit more costly for owners in high-tax states. States responded with an elective entity-level tax designed to shift the payment to the business, which can deduct it federally as a business expense. It has become a significant planning tool, and one where details matter.

The problem it addresses

Individuals who itemize can deduct state and local income and property taxes only up to a federal cap. The cap was $10,000 under the 2017 law and was increased for a period under 2025 legislation, with phase-downs for higher-income taxpayers, so confirm the current rules. Business owners whose state tax on pass-through profit exceeds the cap effectively lose the federal deduction for the excess.

Taxes paid by a business on its own behalf are ordinarily deductible in computing business income. The IRS indicated in guidance that it would treat state entity-level taxes paid by partnerships and S-corporations as deductible in computing non-separately stated income, and would not apply the cap to them, when imposed on the entity. That guidance opened the door for states to design elective entity-level taxes.

How a PTET works in general

1. The entity elects into the state's PTET (an annual election in most states, with a deadline).
2. The entity pays state income tax at the entity level on the owners' share of income, at a stated rate or a computed rate.
3. The entity deducts the tax on its federal return, reducing income passed to owners.
4. The owners receive a credit or exclusion on their state returns for their share of the tax paid by the entity, so they do not pay state tax twice.
5. The federal benefit: the owners' federal taxable income is lower by the amount of the deducted entity tax, without regard to the individual SALT cap.

Details vary. In some states the credit is refundable or can be carried forward. In others, the credit is limited to the owner's state tax liability. Nonresident owners may or may not receive a credit in their home state for tax paid to the PTET state.

Who may benefit

• Owners of profitable S-corps or partnerships in states with PTETs and with state tax on business income exceeding the individual SALT cap.
• Owners who itemize or would otherwise lose the deduction due to the cap. Owners who take the standard deduction receive an indirect benefit as the entity deduction lowers pass-through income.
• Owners in multiple states, where PTETs in some states can shift the deduction for nonresident tax.

Who may not benefit

• Owners below the SALT cap who already deduct state taxes fully.
• Owners in states with no PTET or no state income tax.
• Owners whose entity income is low relative to the cost of the additional filing.
• Owners subject to alternative minimum tax in ways that reduce the benefit.
• Owners with mismatched state credit rules, for example when the home state does not provide a credit for another state's PTET.
• Owners who want to reduce QBI limitations: the PTET deduction reduces qualified business income, which can reduce the QBI deduction. See QBI deduction.

Deadlines and payment timing

Election deadlines and payment schedules differ. Some states require the election by a date before the year starts or with the first estimated payment. Some require estimated payments during the year, with a final payment by a set date. Others allow payment by the entity return due date. The payment must generally be made in the tax year to be deductible in that year at the entity level (with special rules for payments made early in the following year in some states). Missing the deadline may forfeit the election for the year.

Also, an S-corp using the accrual method may take the deduction differently. Coordinate with your preparer before year end, because the payment timing is crucial.

Effects on owners' basis and estimated payments

• PTET payments reduce the owner's basis in the entity in the same manner as other deductible expenses.
• Owners may need to reduce their own state estimated payments to account for the credit.
• Entity cash flow must fund the payment, reducing distributions.

Federal rules in flux

Federal legislation has addressed the SALT cap and could address PTETs or their treatment in the future. Anticipate that the analysis changes when the federal cap changes. If a cap increase makes individual deductions more available, the relative benefit of a PTET may decline. Review each year.

State-specific examples

Some states with large business populations, including California and New York, have PTET regimes with their own rates, deadlines, and credit rules. Do not assume a rule from one state applies in another. Consult current guidance.

Reporting

The entity reports the tax as a deduction on its return, and provides information to owners about the credit. The owners claim the credit or exclusion on their state returns. The federal K-1 shows the reduction in income. If a nonresident owner has a credit issue, the owner's resident state return needs review.

Common mistakes

1. Electing without modeling the impact on owners.
2. Missing the election deadline.
3. Making payments in the wrong tax year.
4. Ignoring the effect on QBI.
5. Not coordinating with owners who live in different states.
6. Reducing distributions without planning liquidity.
7. Not adjusting estimates.
8. Overlooking the interaction with the individual SALT deduction if the cap changes.

Planning approach

1. Identify states where the entity has income and where owners reside.
2. Confirm whether each state has a PTET and what the election requires.
3. Model the federal benefit, the state credit rules, and the QBI effect.
4. Plan cash flow for the payments.
5. Calendar the election deadline and payments.
6. Revisit yearly as law changes.
