S-Corp PTET Election: The SALT Cap Workaround Explained

TLDR

The pass-through entity tax (PTET) election lets an S-corp pay state income tax at the entity level. It deducts that tax federally as an ordinary business expense. The tax no longer flows through to the owner’s personal return, where it would be capped by the $40,400 SALT deduction limit for 2026 (it shrinks by 30 cents for each dollar of income over $505,000 of MAGI, and stops shrinking at $10,000). More than 35 states have PTET regimes as of 2026.

Texas, Florida, Nevada, Washington, Wyoming, South Dakota, New Hampshire, and a handful of others don’t (they have no personal income tax)

. In most states the owner gets a credit for the tax the business paid. The size of the credit can differ. Some states give less than 100%. The federal deduction is captured at the entity level. It skips the SALT cap entirely. For S-corp owners in PTET-eligible states with state-tax liability above the SALT cap, the federal savings typically run $3,000 to $15,000 a year: roughly the state tax trapped above the cap, multiplied by the owner’s federal marginal rate. For example, an owner with $25,000 of state tax and a $10,000 SALT cap (phased-out high earner) at a 32% federal rate saves about ($25,000 − $10,000) × 32% = $4,800 a year.

#Why PTET exists

The 2017 Tax Cuts and Jobs Act capped the SALT (state and local tax) itemized deduction at $10,000 per return. The cap hit high-income owners hardest, especially in high-tax states like New York, California, New Jersey, Massachusetts, and Connecticut. A New York S-corp owner with $400K of K-1 income would owe about $28K in New York state tax. But they could only deduct $10K of it federally. That cost roughly $6K in extra federal tax a year, compared to the pre-TCJA regime.

State governments and tax practitioners responded with the PTET workaround. Here is the mechanism. State law lets a pass-through entity (S-corp or partnership) elect to pay state tax at the entity level. The entity-level tax payment is a deductible business expense for federal purposes. It is not subject to the SALT cap, because it is an entity-level expense, not an itemized deduction. The owner then gets a state-level credit for the entity-paid tax on their personal state return.

The IRS blessed this approach in Notice 2020-75. In Notice 2020-75 the IRS said the entity may deduct state income tax it pays at the entity level. Owners can rely on it. Since then, more than 35 states have enacted PTET regimes.

For 2026 the limit is $40,400. It shrinks by 30 cents for each dollar of income over $505,000. It stops shrinking at $10,000. This holds for most filers, not only joint filers. OBBBA (2025) raised the SALT cap from $10K to this higher limit starting in 2025. This narrowed, but did not remove, the PTET benefit. For owners above the SALT cap, which is most high-income S-corp owners, PTET still saves federal tax on the state tax above the cap. The higher limit is set to end after 2029. In 2030 the limit goes back to $10,000, so PTET may help more people again.

#How PTET works mechanically

Walk through a concrete example. Single-owner S-corp in New York. $300K of K-1 income flowing to the owner. New York personal income tax on $300K ~= $20,000.

How $20K of state tax flows, without vs with the PTET election
	Without PTET	With PTET
Who pays the state tax	Owner pays $20K New York tax personally	Corp pays $20K New York tax at the entity level
Federal deduction for the $20K	Itemized on Schedule A, squeezed under the SALT cap	Deducted as an ordinary business expense: no SALT cap
K-1 income to the owner	$300K (full amount flows through)	$280K (the $20K entity deduction drops pass-through income)
Owner's state credit	None	$20K PTET credit offsets the personal state tax owed
Net federal savings	Limited to whatever fits under the SALT cap	$20,000 × 32% = $6,400/yr

#Without PTET election

Corporation distributes $300K to owner.
Owner reports $300K K-1 income, pays $20K New York state tax personally.
This example does not show a real benefit at $300K income under the cap. PTET helps only when the cap is already used up. Example: a joint filer with $700,000 of income has a 2026 limit of $10,000. Property tax already uses it up. With PTET, the business deducts the state income tax instead.
At $700K AGI, combined property + state tax = $35K. SALT deduction capped at $10,000 (2026 floor, phasing down from $40,400 at $505,000 MAGI). Lost roughly $25,000 of deduction.
At $700K the joint filer is in the 35% bracket. Lost deduction of about $25,000 x 35% is about $8,750.

#With PTET election

Corporation makes PTET payment of $20K directly to New York.
Corporation deducts $20K as state tax expense at the entity level.
K-1 income flowing to owner = $300K − $20K = $280K (the entity-level deduction reduces pass-through income).
Owner receives a $20K PTET credit on their NY personal return, fully offsetting the state tax they would have owed.
Owner’s federal AGI is reduced by $20K compared to non-PTET scenario.
Federal tax savings: $20,000 × 32% = $6,400 (on the entity-level deduction).
Plus the owner still gets to deduct property tax + remaining SALT ($15K) on Schedule A, up to the SALT cap.

Net PTET benefit (assumes the cap is already used up at $700K AGI): If the cap is already full from property tax, the whole $25K of state income tax moves outside the cap. At a 35% bracket that is about $8,750 of annual federal savings for this profile.

For higher-income owners above the SALT phase-out, the PTET savings can hit $10K–$20K/yr because the alternative (lost SALT deduction) is more painful.

#State-by-state PTET status (2026)

States with PTET regimes (more than 35 + DC):

Alabama, Arizona, Arkansas, California, Colorado, Connecticut, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, Utah, Virginia, West Virginia, and Wisconsin. Each state has its own rules and deadlines. Check your state’s tax site.

States without PTET (no state income tax: workaround not needed):

Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming. New Hampshire’s interest and dividends tax was repealed for tax periods starting January 1, 2025. It no longer taxes personal income, so it belongs on this list.

States without PTET despite having income tax (no workaround available):

Delaware, North Dakota, Pennsylvania, Vermont have personal income tax but have not enacted PTET regimes (check each state’s revenue site, since this changes). S-corp owners in these states cannot use the workaround.

For ETS clients, the relevant geography matters:

Texas-based owners: No state income tax, no PTET needed. The SALT cap doesn’t materially affect them on the income tax side.
Multi-state owners with operations in PTET states: Often eligible to elect PTET for the portion of income sourced to those states. We model this case-by-case.

#Election mechanics: state by state

Every state’s PTET regime has different details. Common elements:

Election timing. Most states require the PTET election to be made annually, with timing varying:

California: elect on the original return (Form FTB 3804). A first payment is due June 15 of the tax year. Check FTB rules for the penalty if it is late
New York: by March 15 of the tax year
Illinois: make the election on the entity return. It locks after the extended due date

Election method. Some states use a check box on the entity return. Illinois uses its entity return. New York needs an online election each year by March 15. A person who can legally act for the business must make it. A tax preparer cannot make it for you.

Quarterly estimated tax payments. Most PTET states require quarterly estimated tax payments by the entity, similar to corporate income tax estimates.

Owner credit. Each state has its own credit mechanism. Some give a refundable credit (NY); some give a non-refundable credit limited to the owner’s state tax liability (CA).

Composite vs. PTET interaction. Some states’ PTET regimes interact with composite return rules. Multi-state owners need careful coordination here.

Given the complexity, PTET election is one of the higher-value tax planning conversations we have with any S-corp client in a PTET state.

#Who benefits most from PTET

Does PTET fit your situation?

Where do you owe state income tax, and how much is above the SALT cap?

Recommended High-tax state, liability above the cap
Strong fit

Single- or multi-state owner in CA, NY, NJ, MA, IL, MN, or anyone in the $500K+ SALT phase-out range where the cap is sliding back to $10K. This is where PTET pays the most.
State tax at or below the SALT cap
Marginal fit

If your cap already covers all your state tax, PTET usually saves no federal tax. Then the fee is not worth it. We model it before electing.
No state income tax, no PTET regime, or a sole prop
No fit

TX, FL, NV and the other no-income-tax states don't need it. States with income tax but no PTET (PA, DE, ME) can't use it. Sole props on Schedule C don't qualify.

PTET only works for S-corps and partnerships: never single-member LLCs taxed as sole proprietorships.

Strong fit:

Single-state S-corp owners in high-tax states (CA, NY, NJ, MA, IL, MN)
Multi-state S-corp owners with significant income sourced to PTET states
Owners with state tax liability above the SALT cap
Owners in the SALT phase-out range (incomes >$500K MFJ) where the SALT cap is phasing back to $10K
Service businesses with concentrated owner income

Marginal fit:

Owners with state tax liability below the SALT cap (after property tax)
Single-state owners in low-tax states where the federal savings barely exceed the compliance cost

No fit:

Texas, Florida, Nevada, and other no-state-income-tax owners
Owners in states without PTET regimes (Pennsylvania, Delaware, Maine, etc.)
Pass-through entities other than S-corps and partnerships (sole props don’t qualify)

#The math: when PTET is worth it

The PTET federal benefit equals roughly:

PTET benefit ≈ (State tax above SALT cap available) × Federal marginal rate

For an owner with $25K of state tax above the $10K SALT cap (high-income, phased-out), and 32% federal marginal rate: ($25K - $10K) × 32% = $4,800 of annual federal savings using the above-the-cap formula.

Take an owner with $15K of state tax and $40K of SALT cap available (not yet phased out). There may be no net benefit, because the full state tax is already deductible federally through the SALT itemized deduction.

The post-OBBBA $40K SALT cap means PTET’s marginal value is highest for the highest-income owners: those in the SALT phase-out range or above. For mid-range earners, the $40K cap often covers all of their state tax, which wipes out the PTET benefit.

We model PTET for every S-corp client in a PTET state to determine the actual benefit.

#Implementation timeline

For a clean PTET implementation in California (as an example):

4–6 weeks before election deadline:

Confirm S-corp’s PTET eligibility (must be S-corp or partnership; corporations excluded)
Model federal tax benefit vs. compliance cost
Confirm owner consent (PTET election typically requires owner sign-off)

At election:

File PTET election form with the state (or check the box on the return)
Begin quarterly PTET estimated tax payments by the entity

Throughout year:

Track PTET payments made by the entity
Coordinate with owner’s personal state return to claim the PTET credit
Reconcile any over/underpayment at year-end

At year-end:

The federal deduction counts in the year you pay the tax. To deduct it for 2026, make the payment by December 31, 2026, if your state allows it.
Entity issues K-1 with PTET credit information
Owner files personal state return claiming PTET credit

The annual workflow adds about $300 to $800 in extra preparation fees. It typically saves $3K to $15K in federal tax for owners above the SALT cap.

#Common questions

Does PTET work for single-member LLCs taxed as sole proprietorships? Generally no. PTET regimes apply to S-corps and partnerships (multi-member LLCs taxed as partnerships). Single-member LLCs taxed as sole proprietorships file Schedule C (not a separate entity-level return) and don’t qualify for PTET.

What if I’m a partial-year resident of a PTET state? The state-source income (allocated to the PTET state) is generally eligible for PTET treatment for that state. Multi-state allocation gets complicated for partial-year residents. We model case-by-case.

Does PTET interact with the QBI deduction? PTET-paid tax reduces the entity’s net income for QBI purposes. For non-SSTBs at or above the QBI thresholds, this can affect both QBI eligibility and the W-2 wage limit. For a service business (SSTB), QBI phases out through the range. It is fully cut off above $276,750 single and $553,500 joint for 2026. Between the threshold and that top, it is a partial phase-out, not an immediate zero. PTET lowers the business income used for the QBI deduction, so the QBI deduction drops a little. The interaction requires modeling.

Can I elect PTET retroactively? Most states’ PTET elections are annual and must be made by a specified deadline (often the original return due date or earlier). Retroactive PTET elections are generally not available. If you miss the deadline, you wait until next year.

Does PTET affect basis tracking? The PTET payment is a deduction at the entity level, which reduces pass-through income and therefore reduces stock basis increase for the year. The PTET credit doesn’t directly affect basis. We track both in basis schedules per the basis tracking article.

What if my state changes its PTET rules mid-year? PTET regimes are still evolving. New states adopt them periodically; existing states sometimes amend rules. We monitor state legislation and update client elections accordingly. The IRS Notice 2020-75 framework supports state PTET regimes broadly, so federal treatment is stable even as state rules change.

Can S-corps and partnerships both elect PTET? Yes. Most PTET regimes apply to both. The election mechanics may differ by entity type within a state.

What about non-resident owners? Non-resident owners can typically still benefit from PTET. That is because the entity-level tax payment counts as state tax for federal deduction purposes. The credit on the non-resident state return offsets the non-resident state tax liability. Whether the owner ends up better off depends on the home-state tax rules.

Does PTET trigger any additional federal compliance? The PTET deduction is reported on the entity’s federal return as “Taxes and Licenses” or similar. K-1s may need additional supplemental information showing the PTET payment for owner-level tracking. We handle this in the federal return preparation.

What’s the PTET deadline for current-year planning? Deadlines differ by state. New York needs an online election by March 15 of the year the income is earned. Check your state before the year starts.

Say you are a high-income S-corp owner in a PTET-eligible state and have not evaluated the election. The Discovery call is where we model the federal savings against the compliance cost. We coordinate the state-level election, the quarterly payment cadence, and the owner-credit mechanics, so the workaround actually delivers the federal benefit. We don’t do surprises. You will see the modeled savings before any election is filed. Free advice either way.
