If you advise partnerships, S-corporations, or LLCs taxed as either, you already know the core PTET story: the entity pays state income tax at the entity level, deducts it above the line under IRC 164(a)(3), and owners receive a state credit, turning a blocked individual itemized deduction into a federal deduction the SALT cap cannot touch. What changed in 2026 is the calculus. The One Big Beautiful Bill Act raised the individual SALT cap to $40,400 (verify the current cap and phase-out thresholds at IRS.gov; these amounts were recently enacted under the One Big Beautiful Bill Act, or OBBBA, and are subject to ongoing regulatory interpretation), which reduces or eliminates the PTET benefit for some owners while leaving it fully intact for others. Getting the analysis right now requires modeling three things simultaneously: the SALT savings at the entity level, the Section 199A QBI reduction from the PTET deduction, and each owner's individual tax profile.
There is also a more immediate problem. Several key 2026 PTET election and prepayment windows have already closed. New York's election deadline for calendar-year entities was March 15, 2026. California's prepayment deadline was June 15, 2026. Practitioners reading this guide in July 2026 need to know what is still actionable for the current year, which states still have open windows, and how to position clients for 2027. That is what this guide covers.
This guide is for informational purposes only and does not constitute legal or tax advice. State PTET election rules, deadlines, and credit calculation mechanics vary significantly by state and change frequently. Verify all procedures and thresholds at the applicable state revenue agency and at IRS.gov before advising any client.
What PTET Is and Why It Matters
The pass-through entity tax is a state-level mechanism where the entity itself -- the partnership, S-corporation, or LLC taxed as either -- pays the state income tax on its owners' share of the entity's income, rather than having each owner pay state tax individually. At the federal level, the entity deducts this state tax payment as a business expense under IRC 164(a)(3). Because the deduction is taken at the entity level, it is above the line and not subject to the federal SALT cap that limits what individual itemizers can deduct for state and local taxes.
IRS Notice 2020-75, issued in November 2020, explicitly authorized this treatment. The Notice confirmed that an entity's payment of a state PTE-level tax is a deductible business expense under federal law, even if the individual owners would otherwise be blocked by the SALT cap from deducting the same amount on their personal returns. This resolved the technical question that had kept many practitioners on the sidelines in 2018 and 2019 after the TCJA capped the individual SALT deduction at $10,000.
On the state side, the structure is generally designed to be revenue-neutral for the state. Owners typically receive a state income tax credit equal to their pro-rata share of the PTET paid on their behalf, which offsets the state tax they would otherwise owe as individuals. The net result, when the mechanics work as intended, is that the state receives the same amount of tax revenue, the owner pays the same amount of state tax (via the credit offset), and the only change is that the owner now has a federal deduction for a state tax payment that the SALT cap would have blocked at the individual level.
The federal benefit is the difference between the owner's marginal federal rate and zero, applied to the PTET amount. For a 37% bracket owner with $100,000 in state income tax otherwise blocked by the SALT cap, an effective PTET election can produce roughly $37,000 in federal tax savings. That number changes substantially when you factor in the OBBBA's raised SALT cap and the QBI interaction, which is why the analysis matters more now than it did when the $10,000 cap made every high-income pass-through owner an obvious PTET candidate.
For a broader overview of OBBBA's tax changes affecting practitioners across service areas, see the OBBBA tax preparer practice guide for 2026. For OBBBA's international tax changes, including the GILTI-to-NCTI rename and Form 8992 updates, see our NCTI practitioner guide.
How OBBBA Changed the Calculus
Under TCJA (2017), the individual SALT deduction was capped at $10,000 per return regardless of filing status. With state income taxes for high-income pass-through owners frequently exceeding that threshold by multiples, virtually every owner with meaningful state tax exposure was a candidate for PTET. The analysis was almost always: yes, elect.
OBBBA changed that. The SALT cap is raised to $40,400 for 2026, with a phase-out beginning at $500,000 of AGI (verify the current SALT cap amount, phase-out threshold, and phase-out rate at IRS.gov; these figures were recently enacted under the One Big Beautiful Bill Act and are subject to ongoing regulatory interpretation). The raised cap means that for some owners, the individual SALT deduction now covers their entire state tax liability, which eliminates the PTET advantage for those owners specifically.
The four owner profiles to model
Owner below $40,400 in state tax and below $500,000 AGI
For this owner, the raised SALT cap covers the full state tax liability. They can deduct the entire amount as an individual itemized deduction if they itemize. The PTET no longer produces a federal benefit for this profile, and the QBI reduction (discussed in Section 3) means an unnecessary PTET election would actually create a small net cost. These owners should not be included in PTET elections solely on the basis of prior-year planning if their state tax and income levels have not changed materially.
Owner in the AGI phase-out zone (above $500,000)
The individual SALT cap phases out as AGI climbs above $500,000 (verify the specific phase-out computation at IRS.gov). For these owners, the SALT cap available at the individual level is reduced or eliminated entirely, which restores PTET's value. The entity-level PTET deduction is not subject to the phase-out because it is taken above the line at the entity. High-income owners remain the clearest PTET candidates post-OBBBA. Verify current phase-out thresholds at IRS.gov before advising, as the phase-out rate and ceiling affect the precise calculation.
Standard deduction filer
The SALT cap increase means nothing to an owner who takes the standard deduction, because they receive no itemized deduction for state taxes regardless. PTET remains the only mechanism that produces a federal deduction for state income tax on pass-through income for standard deduction filers. The benefit is preserved in full for this group.
Multi-owner entities with mixed profiles
PTET elections are made at the entity level and typically bind all owners. A single election may benefit high-AGI owners (whose individual SALT cap has phased out) while being neutral or slightly negative for lower-AGI owners who can now deduct their state taxes directly. Before recommending an election for a multi-owner entity, model each owner's situation individually. Where the election produces sharply different outcomes across the owner group, the affected owners may need to negotiate side agreements or adjustments to distributions to account for the differential impact.
The QBI Ordering Risk
This is the interaction that most practitioners underweight, and the one most likely to produce an unexpected net cost when PTET payments are increased in response to post-OBBBA planning.
PTET payments reduce the entity's federal taxable income as a state tax deduction under IRC 164(a)(3). Qualified business income (QBI) for the Section 199A deduction is calculated on the entity's net income after all deductions -- including the PTET deduction. A larger PTET payment therefore means less QBI available for the 20% deduction.
To make this concrete: an S-corp reports $500,000 in net income before any PTET payment. The entity pays $30,000 in PTET. The QBI available for Section 199A is now $470,000, not $500,000. The 20% deduction on $470,000 is $94,000, compared to $100,000 on the pre-PTET income. The PTET deduction costs $6,000 of the 199A benefit. The net federal savings from the PTET election is the SALT benefit minus this $6,000 QBI reduction. For owners near the 199A phase-in range, or for entities with high PTET exposure relative to income, the QBI offset can be substantial.
The sequencing -- PTET deduction reduces entity income first, then QBI is calculated on the net amount -- was not changed by OBBBA. It was confirmed in the regulatory guidance context (including Rev. Proc. 2025-32 and prior IRS guidance following Notice 2020-75). What OBBBA did change is the 199A landscape around it: Section 199A is now permanent under OBBBA, a $400 minimum deduction applies, and the phase-in range was expanded. Verify all OBBBA Section 199A provisions at IRS.gov; they are recently enacted and subject to ongoing regulatory guidance. For a detailed analysis of the OBBBA Section 199A changes, see the Section 199A QBI deduction and OBBBA practitioner guide.
MODEL THE QBI OFFSET BEFORE ADVISING A PTET INCREASE
Increasing PTET payments to capture the state tax deduction reduces QBI available for the Section 199A deduction. For owners near the 199A phase-in range or with high PTET exposure, this interaction can eliminate a substantial portion of the expected federal benefit. Run both calculations before advising.
The practical workflow is: (1) calculate the tentative federal SALT savings from the PTET deduction at the owner's marginal rate; (2) calculate the reduction in the 199A deduction caused by the lower QBI base; (3) net the two figures to determine whether the election produces a genuine federal benefit. Do not advise a PTET election or an increase in prepayments based solely on the SALT savings estimate without completing step (2).
2026 Deadline Tracker: What Has Passed and What Remains
As of July 21, 2026, two of the highest-volume PTET deadlines have already passed. Practitioners must know which 2026 windows are closed before advising clients on current-year options.
2026 DEADLINES ALREADY PASSED: NEW YORK AND CALIFORNIA
New York's annual PTET election deadline for calendar-year entities was March 15, 2026. California's 2026 prepayment deadline was June 15, 2026. Both windows are closed as of this guide's publication date. Practitioners with affected clients should focus on remediation options (described below) and begin 2027 planning now.
| State | 2026 Key Deadline | Status (as of July 21, 2026) | Action |
|---|---|---|---|
| New York | March 15, 2026 (calendar-year election) | PASSED | Verify estimated payment adjustment options with NY Department of Taxation and Finance. Plan 2027 election by March 15, 2027. |
| California | June 15, 2026 (prepayment); election on timely filed return | PREPAYMENT PASSED | Consult CA Franchise Tax Board guidance for 2026 options. A missed prepayment may affect the credit amount; verify at FTB.ca.gov. |
| New Jersey | S-corps: March 15; Partnerships: typically April 15 | LIKELY PASSED | Verify current election and extension options at NJ Division of Taxation before advising. |
| Connecticut | Varies by entity type | Verify at CT DRS | CT was among the first states to enact PTET. Verify current deadlines and mechanics at the CT Department of Revenue Services. |
| Illinois | Varies | Verify at IDOR | Verify election timing and payment requirements at the Illinois Department of Revenue. |
| Virginia | Varies | Verify at VA TAX | Verify current election procedures and payment deadlines at the Virginia Department of Taxation. |

| Wisconsin | Varies | Verify at WI DOR | Verify current PTET election requirements at the Wisconsin Department of Revenue. |
| Colorado | Varies | Verify at CO DOR | Verify current PTET rules and election timing at the Colorado Department of Revenue. |
STATE-SPECIFIC VERIFICATION REQUIRED
State PTET election mechanics, deadlines, prepayment requirements, and credit refund rules vary significantly by state and change frequently. This guide reflects general principles as of July 2026. Before advising any client on PTET elections, verify current election deadlines, prepayment requirements, and credit calculation rules at the applicable state revenue agency. Nothing in this guide constitutes advice on any specific state's PTET law.
What to do if you missed the 2026 deadline
For New York clients where the March 15 election window has closed: the NY PTET regime allows certain adjustments to estimated payments even after the election deadline. The path forward depends on whether an election was made for a prior year (annual elections must be renewed) and whether estimated payment adjustments can still capture part of the benefit for 2026. Contact the NY Department of Taxation and Finance directly, or review current guidance on the DTF website, before advising any remediation strategy. Do not assume the 2026 year is a total loss without checking current DTF guidance.
For California clients where the June 15 prepayment deadline has passed: California's PTET election is made on the timely filed return rather than through a standalone election, which means the election for tax year 2026 may still be available when the return is filed. However, the prepayment requirement -- California requires an electing entity to pay a minimum amount by June 15 to qualify for the credit in that year -- may not be satisfiable after the deadline has passed. Verify the current consequences of a missed prepayment at FTB.ca.gov before advising any California PTET client.
The immediate priority for clients who have missed 2026 deadlines is to calendar 2027 elections now. Most state PTET deadlines fall in the first calendar quarter for the prior tax year; a practitioner who does not build a 2027 PTET calendar before the end of 2026 will face the same problem next year.
When PTET Still Makes Sense Post-OBBBA
The raised SALT cap did not eliminate PTET; it created a threshold question that did not exist before. The decision framework below identifies the four scenarios where PTET continues to produce a net federal benefit after accounting for the OBBBA changes and the QBI interaction.
Owner's state tax liability exceeds $40,400
Even with the raised SALT cap, the individual deduction covers only the first $40,400 in state and local taxes (verify the current cap at IRS.gov; recently enacted under OBBBA and subject to ongoing regulatory interpretation). Any amount above that threshold remains blocked at the individual level. The entity-level PTET deduction captures the full state tax liability -- including the excess above the cap -- as a federal deduction. For owners with state income taxes substantially above $40,400, PTET retains most or all of its pre-OBBBA value, reduced only by the QBI offset discussed in Section 3. Model the excess above the cap to size the remaining PTET benefit.
Owner's AGI exceeds $500,000 (phase-out zone)
The individual SALT cap phases out for high-income owners whose AGI exceeds the phase-out threshold (verify the current phase-out starting point and rate at IRS.gov; recently enacted under OBBBA). As the cap phases down, the individual deduction available to the owner shrinks, and the PTET advantage relative to individual deductibility grows. For owners above the full phase-out ceiling, the SALT cap is effectively zero at the individual level, and the PTET captures the entire state income tax as an above-the-line federal deduction. High-income owners remain the clearest and most unambiguous PTET candidates after OBBBA. Verify the specific phase-out mechanics at IRS.gov.
Owner takes the standard deduction
A standard deduction filer receives no benefit from the SALT cap increase because they do not itemize at all. Their individual state tax deduction is zero, full stop. PTET is still the only mechanism that converts a state income tax obligation on pass-through income into a federal deduction for these owners. The SALT cap change is irrelevant to the analysis. Standard deduction filers who own interests in eligible pass-through entities should evaluate PTET elections on the same basis they would have under the old $10,000 cap, accounting only for the QBI reduction offset.
Multi-owner entities with mixed owner profiles
The entity-level election applies to all owners equally: the same PTET is paid, the same deduction reduces entity income, and each owner's K-1 reflects the reduced distributive share. But the benefit each owner derives from the election depends entirely on their individual situation. A two-owner S-corp where one owner is above $500,000 AGI and the other is below $40,400 in state tax and below the phase-out may find that the election strongly benefits owner A and is neutral or slightly negative for owner B. Document the individual analysis for each owner and have an owner-level discussion before making the election. In some cases, a partial PTET payment structure or economic adjustments between owners may be appropriate. Consult state law and operating agreement terms before structuring any side arrangement.
Election and Payment Mechanics
Understanding the mechanical steps is a prerequisite to advising correctly -- and to avoiding the errors that most commonly generate unexpected tax costs for clients.
How the election is made
The PTET election is made at the entity level, not by individual owners. In most states, once the election is made for a tax year, it applies to all owners and all income for that year; individual owners generally cannot opt out. The state-specific election mechanism varies: some states (like New York) require a separate affirmative election on the state's online portal by a specified date; others (like California) treat the election as made when the entity pays the required prepayment or files the return with the PTE tax included. Verify the election mechanics at the applicable state agency before advising any client on timing.
Federal deduction timing
The entity deducts the PTET payment in the tax year in which it is paid (for cash-method entities) or in the year in which it is accrued (for accrual-method entities). A cash-method S-corp that makes its PTET payment in January 2027 for tax year 2026 takes the deduction in its 2027 federal return, not its 2026 return. Practitioners advising clients on the timing of PTET payments must account for this rule when optimizing the year in which the federal deduction is realized.
Owner-level treatment: K-1, credits, and the state return
When the entity pays PTET, each owner's distributive share of income is reduced by the entity's PTET deduction before the income flows to the K-1. The owner does not separately deduct the PTET on their federal return; the deduction is already embedded in the reduced K-1 income they report. On the state return, the owner excludes the income on which the entity already paid PTET (because the entity paid the tax, not the individual) and claims a state income tax credit equal to their allocated share of the PTET paid.
This credit structure is what makes PTET tax-neutral at the state level: the owner would have owed state tax on their share of income, but the entity paid it, and the credit offsets the owner's individual state liability by the amount the entity already paid. If the credit exceeds the owner's state liability, the refundability rules of the specific state determine whether the excess credit is refunded, carried forward, or lost. Verify the credit refundability rules for each state where the entity operates.
S-corp shareholder basis
In an S-corporation, the PTET payment reduces the corporation's net income before allocation to shareholders. Each shareholder's pro-rata share of income is therefore reduced by the share of PTET allocable to them. Because the shareholder's income allocation increases their basis, a reduced income allocation means a smaller basis increase than would have occurred without the PTET payment. Practitioners preparing S-corp shareholder basis schedules must include the PTET effect in the computation. For entities with closely managed basis positions (for example, where shareholders are near zero basis and monitoring loss deductibility), this reduction can affect loss planning and distribution planning in the same year. See the Form 2553 S-corp election guide if there are any questions about the entity's S-corp status before proceeding with PTET planning.
Partnership mechanics
For partnerships, the PTET payment is generally allocated among partners according to their pro-rata ownership or as specified in the partnership agreement. Each partner's K-1 reflects the reduced distributive share of income after the entity-level PTET deduction, and each partner claims their allocated share of the state credit on their individual state return. The partnership's PTET payment does not create a separately stated item for federal purposes in the same way that charitable contributions or investment interest do; the reduction is embedded in the net income or loss allocated to each partner. Verify how the applicable state's guidance requires the PTET allocation to be reported on the K-1 and on the state return, as states differ.
Retroactive elections
Some states permit retroactive PTET elections for prior tax years; others do not. For practitioners with clients who missed a prior-year election window, the first step is to determine whether the state permits a late or retroactive election and whether an amended return is a viable path. Do not assume retroactive elections are available in any state without verifying current state agency guidance. The rules on late elections have changed in several states over the past two years, and a retroactive election that was permitted in 2023 may not be permitted under current guidance.
Interaction with S-Corp Reasonable Compensation
PTET payments made by an S-corp reduce the entity's net income before calculating QBI. Practitioners advising on S-corp salary levels should include PTET in the income modeling, as a higher PTET payment reduces both the QBI base (affecting the 199A deduction amount) and the net income available for distributions. The salary vs. distribution balance that optimizes employment tax exposure does not operate in isolation from the PTET effect; a salary level that was optimal before a PTET election may require adjustment once the PTET payment is included in the income model. See the S-corp reasonable compensation practitioner guide for the full salary vs. distribution analysis that interacts with these calculations.

Frequently Asked Questions
Does the OBBBA SALT cap increase eliminate the PTET benefit?
Not for all owners, and not in all circumstances. The OBBBA raised the individual SALT cap to $40,400 (verify the current cap and phase-out thresholds at IRS.gov; recently enacted and subject to ongoing regulatory interpretation). For owners whose state tax liability falls below this threshold and whose AGI is below the phase-out range, the PTET benefit is reduced or eliminated because they can now deduct state taxes directly. However, PTET retains full value for owners in the phase-out zone (AGI above $500,000; verify at IRS.gov), for standard deduction filers, and for any owner whose state tax liability exceeds $40,400. The analysis must be run individually for each owner, not assumed to be uniformly positive or uniformly negative.
How does a PTET election interact with the Section 199A QBI deduction?
PTET payments reduce the entity's net income as a deduction under IRC 164(a)(3). Because QBI for Section 199A is calculated on income after all deductions, a higher PTET payment produces a lower QBI base and a lower 199A deduction. For example: an S-corp with $500,000 in income before PTET pays $30,000 in PTET, leaving $470,000 of QBI. The 20% deduction falls from $100,000 to $94,000, a $6,000 reduction. This QBI offset must be modeled before advising any PTET election or prepayment increase. Verify all OBBBA Section 199A provisions at IRS.gov; recently enacted and subject to ongoing regulatory guidance. For a full analysis, see the Section 199A QBI deduction and OBBBA practitioner guide.
What happens if we missed the 2026 PTET election deadline in our state?
The answer depends on the state. New York's election deadline for calendar-year entities was March 15, 2026, and that window has closed; however, NY allows certain estimated payment adjustments even after the election window passes, so verify current remediation options with the NY Department of Taxation and Finance. California's June 15 prepayment deadline has also passed; California's election is made on the return rather than through a separate affirmative election, so consult current CA Franchise Tax Board guidance to determine what 2026 options remain. For other states, verify the current election and amendment rules directly with the applicable state revenue agency. Begin planning 2027 elections immediately -- most deadlines fall in the first calendar quarter -- to avoid repeating the problem.
Does PTET apply to S-corporations as well as partnerships?
Yes. Most states that have enacted PTET make the election available to both S-corporations and partnerships, as well as LLCs taxed as either. For S-corporations, the PTET payment reduces corporate income before the allocation to shareholders, which affects each shareholder's K-1 income, their basis computation, and the QBI available for Section 199A. Practitioners advising S-corp clients on PTET should verify the entity's S-corp election is in good standing before proceeding; see the Form 2553 S-corp election guide if there are any questions about the entity's status. Verify S-corp PTET eligibility and procedures at the applicable state revenue agency, as some states impose additional conditions.
How do we report PTET payments on the K-1?
For partnerships, the PTET payment reduces distributive share income before it flows to each partner's K-1; partners report the reduced income on their federal return and claim their share of the state credit on their state return. For S-corporations, the PTET payment reduces the corporation's net income before the per-share, per-day allocation to shareholders; each shareholder's K-1 reflects the reduced income allocation. The state credit is claimed by the individual on their state return. Federal K-1 reporting for PTET state credits and the reduced income allocation varies by state; verify current K-1 disclosure requirements for PTET with the applicable state agency and against current IRS guidance on the federal treatment of entity-level state tax payments.
