PTE Election: SALT Cap Workaround for Multi-State LLCs

What the SALT cap is and why it matters

The State and Local Tax (SALT) deduction is the federal itemized deduction for state and local income taxes (or sales taxes), property taxes, and certain other state and local taxes. Before the Tax Cuts and Jobs Act (TCJA) of 2017, the SALT deduction was uncapped on Schedule A; high-income taxpayers in high-tax states (California, New York, New Jersey, Illinois) routinely deducted tens of thousands of dollars in state income tax against their federal taxable income.

The TCJA capped the SALT deduction at $10,000 per year for tax years 2018 through 2025. The cap applied uniformly to all individual filers regardless of income or state of residence. The cap was scheduled to expire after 2025, returning the SALT deduction to its pre-TCJA uncapped state.

The One Big Beautiful Bill Act (OBBBA), signed in July 2025, replaced the scheduled sunset with a higher cap and a phase-out. For tax year 2025 the cap is $40,000 ($20,000 for married filing separately); for tax year 2026 the cap is approximately $40,400, indexed by 1% annually through 2029. A phase-out reduces the cap by 30% of the excess of MAGI over $500,000, with a $10,000 floor. At $600,000 MAGI the deduction reaches the floor and stays at $10,000 for higher MAGI rather than dropping below. The cap is scheduled to revert to $10,000 for all filers in 2030.

How the PTE election bypasses the cap

The Pass-Through Entity Tax (PTE) election lets a partnership or S-corporation pay state income tax at the entity level, then deduct that payment as an ordinary business expense on the federal return. The entity-level state tax is not subject to the $10,000 SALT cap because the cap applies only to individual itemized deductions, not to business deductions on Form 1065 or Form 1120-S.

The state then offers the entity owners a credit on their personal state return for the share of state tax already paid by the entity. The credit reduces or eliminates the owner's personal state tax liability for the same income, which avoids double taxation. The federal benefit is a full deduction of the state tax payment without the SALT cap; the state benefit is the credit that prevents the owner from paying the same state tax twice.

The Internal Revenue Service (IRS) issued Notice 2020-75 in November 2020, confirming the federal treatment of state PTE payments as deductible business expenses. The Notice cleared the path for broader state adoption: state PTE election adoption went from seven states in 2020 (Connecticut, Louisiana, Maryland, New Jersey, Oklahoma, Rhode Island, Wisconsin) to roughly 33 to 36 states by 2026. Earlier OBBBA drafts contemplated limiting Notice 2020-75 and the PTE workaround for certain entity classes, but the final law (enacted July 2025) did not include those provisions. The PTE deduction generally remains available alongside the expanded SALT cap through 2029.

Which entities qualify (S-corp vs Partnership)

PTE election eligibility depends on entity classification, not LLC formation status. The IRS treats LLCs as either partnerships (multi-member default), S-corporations (after a valid Form 2553 election), C-corporations (rare for small LLCs), or disregarded entities (single-member default). The PTE election is generally available only to partnerships and S-corporations because both file an entity-level state tax return.

Single-member LLCs taxed as disregarded entities do not qualify in most states because the LLC's income passes through to the owner's personal return without an entity-level state return. A single-member LLC owner who wants access to the PTE workaround typically files Form 2553 to elect S-corporation status, then makes the PTE election at the state level. The S-corp election adds payroll, reasonable salary, and entity-level filing obligations; the PTE benefit has to outweigh the added administrative cost.

C-corporations do not qualify for the PTE election because C-corp income is not pass-through; the C-corp pays its own federal and state income tax and the owners pay tax again on dividends. The SALT cap does not apply to C-corp owners on the entity side, so the workaround is irrelevant.

PTE elections are widely available across US states

PTE adoption spread quickly after IRS Notice 2020-75. By 2026, roughly 33 to 36 US states (plus New York City as a separate municipal election) allow some form of PTE election; the count varies across trackers depending on whether mandatory entity-level taxes (DC, NH, TN, TX) and proposed-but-not-yet-effective regimes (Delaware) are included. The mechanics vary state by state: the tax rate ranges from approximately 3% to 13.3%, the election deadlines differ (some states require the election by the original return due date, others allow it on the return itself), and the credit calculation methodology differs.

Verify the current PTE state list on the AICPA Pass-Through Entity Tax tracker (aicpa-cima.com) or the Tax Foundation PTE tracker (taxfoundation.org). The list updates periodically as new states adopt and as existing state mechanics change.

How OBBBA changes the SALT cap from 2025 onward

The OBBBA SALT cap structure changes the value of the PTE election compared to the 2018 to 2024 era. Three tax years matter: 2024 (final year of the $10,000 TCJA cap), 2025 (first year of the $40,000 OBBBA cap with the 30%-above-$500,000 MAGI phase-out down to a $10,000 floor), and 2026 (cap indexed to approximately $40,400 with the same phase-out structure).

The PTE election value depends on the founder's MAGI relative to the phase-out band. Below $500,000 MAGI, the personal SALT deduction can absorb most or all state income tax up to the $40,000 cap, so the PTE election provides marginal additional federal benefit. In the $500,000 to $600,000 MAGI phase-out band, the personal cap is sliding toward $10,000, so the PTE election captures the federal deduction that the personal SALT cap is losing. Above $600,000 MAGI, the personal SALT cap is fully phased back to $10,000, and the PTE election captures most of the federal benefit on state income tax above that floor.

The OBBBA cap is currently legislated through 2026; the long-term path is uncertain because the OBBBA itself replaced an earlier scheduled SALT cap sunset. Founders running a multi-year tax projection should treat the OBBBA cap as the planning baseline for 2025 and 2026 and revisit the projection annually as Congress considers extensions, modifications, or replacement of the cap.

Multi-state nexus and the PTE decision matrix

Multi-state LLCs face the PTE decision state by state. A Delaware-formed LLC operating from California, New York, and Illinois has three separate state PTE decisions, plus the Delaware question (Delaware does not impose a state-level PTE because Delaware LLCs are typically taxed at the owner level rather than entity level for state income tax purposes). Each state's election is independent, and the math has to work in each state for the election to be worth the administrative cost.

The state-by-state decision depends on three factors: whether the state allows PTE at all, the state's PTE tax rate compared to the personal income tax rate the owner would otherwise pay, and the owner's MAGI relative to the OBBBA phase-out. A state with a high PTE rate (California at 9.3%) and a high owner MAGI (above $600,000) typically yields the strongest PTE benefit. A state with a low PTE rate and an owner below the SALT cap phase-out provides marginal benefit; the administrative overhead of the entity-level filing may exceed the federal savings.

PTE eligibility is tied to foreign qualification: a Delaware LLC operating from California must register as a foreign LLC there before making the California PTE election. The foreign qualification confirms the LLC is doing business in California and gives the California Franchise Tax Board the basis to accept the PTE election and the entity-level California return. The foreign qualification 50-state guide covers the trigger thresholds state by state.

1. 1Identify all states where the LLC has nexus (physical presence, employees, inventory, regular customer revenue above the state threshold).
2. 2Check the AICPA PTE state tracker to confirm which of those states allow PTE elections.
3. 3For each PTE state, compare the state PTE rate to the owner's personal state income tax rate and run the federal SALT cap math against the owner's MAGI.
4. 4File foreign qualification in each operating state where required, before making the PTE election.
5. 5Make the PTE election in each state by the state-specific deadline; some states require quarterly estimated PTE tax payments starting from the election year.
6. 6File Form 1065 or Form 1120-S federally with the entity-level state PTE payment deducted as a business expense.
7. 7Each owner files the personal state return in each PTE state, claims the state PTE credit for the entity-paid share, and reports the federal pass-through income net of the entity-level state tax already paid.

When the PTE election does not work

The PTE workaround is not universally beneficial. Five common scenarios are where the election adds friction without meaningful federal savings. Founders who recognize themselves in these scenarios should run the PTE math conservatively or skip the election entirely.

• Single-member LLC taxed as a disregarded entity in a PTE state: most states require an entity-level return for PTE, and disregarded entities do not file one. The owner has to elect S-corp status (Form 2553) first, which adds payroll, reasonable salary, and Form 1120-S filing obligations.
• LLC operating only in states with no broad-based personal income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming): the PTE election does not apply because there is no broad state income tax to pay at the entity level. The personal SALT cap is the only federal SALT consideration.
• Owner MAGI well below the OBBBA $500,000 phase-out: the personal SALT deduction up to the $40,000 cap typically absorbs most state income tax already, so the PTE election captures little additional federal deduction. The administrative overhead may exceed the savings.
• PTE election made in a state where the PTE tax rate exceeds the personal state tax rate: some states use the top marginal rate for the PTE, which can be higher than the owner's marginal personal rate. The owner pays more state tax in total, even with the federal SALT workaround benefit, which defeats the purpose.
• Owner is a non-resident of the PTE state and the state does not credit non-resident owners properly: a small subset of PTE states have credit calculation rules that disadvantage non-resident owners, so non-resident owners should confirm the credit treatment with a licensed CPA before electing.

How save office aligns with PTE state mapping

save office operates real US business addresses in seven cities. Two of the seven sit in jurisdictions without a state income tax: Tampa Florida and Cheyenne Wyoming. PTE is not relevant for owners operating only in those locations because there is no state income tax to pay at the entity level.

Five of the seven sit in jurisdictions with state income tax. California has an active PTE election at 9.3%, which applies in both Los Angeles and San Francisco. New York has an active PTE election up to 10.9%, which applies in New York City (NYC also has a separate municipal PTE election layered on top of the state). Wilmington Delaware is the formation address for many multi-state LLCs; Delaware enacted PTE legislation that takes effect after the Division of Revenue certifies system readiness, so verify current Delaware PTE status on revenue.delaware.gov before relying on it. Washington DC has its own income tax (4% to 10.75%) and operates an unincorporated business franchise tax structure rather than an elective PTE in the AICPA-tracked sense, so DC treatment for a DC-based LLC typically needs a licensed CPA review before assuming PTE election eligibility.

Multi-state LLCs benefit from the seven-city coverage when the operating address has to match the state where the PTE election is filed. A Delaware-formed LLC making the California PTE election typically registers as a foreign LLC in California first; the Los Angeles or San Francisco address provides the operating address that matches the California foreign qualification and the California PTE election. The same pattern applies to New York City for New York PTE.

The multi-city switching flexibility lets the operating address shift between cities as the LLC's nexus map changes; a startup that opened with California operations and then expanded to New York can switch the operating address without re-filing the LLC. The Address Checker tool runs USPS Delivery Point Validation on the address before it goes on the foreign qualification filing or the state PTE election paperwork. The get-started flow handles the documentation in 24 hours so the address is ready before the state filing deadline arrives.

Common mistakes with PTE elections

• Making the PTE election without checking the OBBBA phase-out math first: owners below the $500,000 MAGI band may capture little federal benefit, while owners above $600,000 MAGI capture most of the benefit. The election is generally irrevocable for the tax year.
• Filing the PTE election in a state without first registering as a foreign LLC: California, New York, and Illinois typically require foreign qualification before accepting the PTE election. The election can be rejected and the entity-level tax payment refunded if foreign qualification is missing.
• Missing the state-specific election deadline: some states require the PTE election by the original return due date (March 15 for partnerships, March 15 or April 15 for S-corps), others allow the election on the return itself. Missing the deadline typically forfeits the election for that tax year.
• Failing to make the state quarterly estimated PTE tax payments: most PTE states require quarterly estimated tax payments at the entity level once the election is made, similar to personal estimated tax. Missed payments trigger interest and penalties at the entity level.
• Treating the PTE credit on the personal return as if it were a deduction: the state PTE credit reduces the owner's personal state tax liability dollar-for-dollar (it is a credit, not a deduction). Reporting it as a deduction on the personal state return is a common preparer error in the first year of PTE adoption.
• Ignoring the multi-state interaction: a Delaware LLC operating in California, New York, and Illinois has three separate PTE decisions, three separate entity-level state returns, and three separate owner-level state credit calculations. The administrative complexity scales linearly with the number of PTE states; a CPA experienced in multi-state pass-through filings is typically worth the fee for LLCs in three or more PTE states.
