Quick answer
PTET moves qualifying state income tax from the owner level to the entity level. IRS Notice 2020-75 treats qualifying entity payments as deductible in computing the partnership’s or S corporation’s federal income, rather than as the owner’s capped personal SALT deduction. State law determines the election, tax base, rate, payment timing, and owner credit.
How the PTET deduction works
- 1
The entity confirms eligibility and elects under state law
Partnerships and S corporations are common eligible entities, but owner and entity restrictions differ.
- 2
The entity calculates and pays the state tax
The state defines the tax base, apportionment, rate, estimates, and payment deadline.
- 3
The entity deducts the qualifying payment federally
Notice 2020-75 says the payment is taken into account in computing the entity’s non-separately stated taxable income or loss.
- 4
The owner receives state-level relief
The state may provide a refundable or nonrefundable credit, carryforward, subtraction, or exclusion.
- 5
The preparer reconciles the federal and state effects
PTET can reduce federal pass-through income and QBI while producing state addbacks, credits, and owner-basis consequences.
The 2026 SALT cap changed the break-even point
For 2026, the personal SALT deduction cap is scheduled to be $40,400 for most filers and $20,200 for married filing separately. The higher amount begins to phase down when modified adjusted gross income exceeds $505,000, with a statutory floor of $10,000, and the temporary regime is scheduled to return to a $10,000 cap in 2030.
PTET is not automatically valuable just because it is available. An owner who already fits all personal taxes under the cap may get little federal benefit, while still bearing extra return, estimate, and cash-flow work. High-income owners can still benefit when the phaseout pushes their usable personal cap down.
Which states offer PTET?
The AICPA’s January 26, 2026 map counted 36 states plus New York City with enacted PTE-level taxes. That snapshot also identified expirations, sunsets, and proposed 2026 bills. Minnesota’s revenue department later published a 2026 election process, illustrating why a static “36 states” sentence is not enough for filing work.
Use the national map only to find the regime. Then open the state revenue department’s current-year election, estimated-payment, entity-return, and owner-credit instructions. Track the source and verification date in the workpaper.

PTET can shrink QBI while increasing the federal state-tax deduction
Because the entity-level tax reduces pass-through business income, it generally reduces the qualified business income used for the Section 199A deduction. For an otherwise eligible owner receiving a 20% QBI deduction, each $10,000 of deductible PTET can reduce tentative QBI deduction by up to $2,000 before other limits. The trade can still be favorable, but use the net federal and state result.
| Entity-level PTET paid | $10,000 |
| Federal deduction before QBI interaction | $10,000 |
| Illustrative QBI reduction at 20% | ($2,000) |
| Net federal deduction base before other effects | $8,000 |
Simplified illustration only. It assumes the owner otherwise receives a full 20% QBI deduction and ignores taxable-income, wage/UBIA, SSTB, basis, loss, state, and timing effects.
The six-point PTET election screen
Entity eligible?
Confirm entity type, owners, and state-specific exclusions. A disregarded single-member LLC often cannot elect without a different tax classification.
Election available for 2026?
Check the state’s current statute, sunset, and filing-year instructions. Several regimes changed or expired around 2025–2026.
Election made on time?
Deadlines and payment prerequisites vary. Some elections are irrevocable after the due date or require estimates before the return.
Owner receives usable relief?
Model resident credit, nonresident credit, refundability, carryforward, addback, and owner-level inclusion.
Federal deduction creates net value?
Compare the federal benefit with reduced QBI, state credit haircut, cash timing, added compliance, and entity-owner mismatches.
Books and returns reconcile?
Entity payment, federal deduction, state addback, K-1 information, and owner credit should trace through one workpaper.
Election and payment deadlines are state-specific
Do not copy another state’s date. A regime may require a separate election, an election on the entity return, quarterly estimates, an early-year prepayment, owner consent, or payment by a specified date to preserve the federal deduction year. Late-election relief is not uniform.
Before year starts
Confirm entity/owner eligibility, expected source income, and state residency mix.
Before each estimate
Reforecast tax base, owners, apportionment, credits, and cash.
Before the election cutoff
Document authorization and verify that required payments have cleared.
Before federal filing
Reconcile books, deduction year, K-1 information, owner credits, and resident-credit positions.
How elections actually get blown
The same five failures account for nearly every broken PTET year we are asked to clean up:
- The missed prerequisite payment. Some regimes condition the election on a mid-year prepayment (California's June payment is the famous one). Miss it and discovering the problem in December is too late for that year.
- The missed election window. Annual-election states (New York's early-year window is the classic) do not accept the intention to elect; entities that never filed the election get no deduction no matter what they paid.
- Paying personal estimates as if PTET did not exist. The owner keeps full personal estimates running alongside entity PTET payments, doubling cash out the door and tangling the credit reconciliation at filing.
- Deduction-year mismatch on cash-basis entities. When the entity pays controls when the federal deduction lands; December versus January payments move real money for cash-basis S corps.
- Multi-state entities electing in one state and forgetting composite or withholding obligations in the others. The PTET fix in the home state does not switch off nonresident mechanics elsewhere.
Cleanup options exist for some of these (amended elections where a state allows them, deduction-year corrections, credit reconciliations), but every one of them is cheaper as a calendar entry than as a project. This is the core of what a year-round engagement does for PTET owners: the deadlines live on our calendar, not the client's memory.
Frequently asked questions
What is a PTET deduction?
A state pass-through entity tax lets an eligible partnership or S corporation pay state income tax at the entity level. Under IRS Notice 2020-75, qualifying entity-level payments may be deducted in computing federal taxable income and are not treated as the owners’ capped Schedule A SALT deduction.
Does every state offer a PTET election?
No. The AICPA map dated January 26, 2026 counted 36 states plus New York City with enacted regimes, but several laws had sunsets or active 2026 legislation. Use the current state tax authority’s filing-year guidance rather than a static national count.
Does a single-member LLC qualify for PTET?
A disregarded single-member LLC usually is not an eligible pass-through entity by itself, although an LLC taxed as an S corporation or partnership may qualify if the state permits it. Entity classification and state owner restrictions control.
Does PTET reduce the QBI deduction?
An entity-level PTET deduction generally reduces the pass-through income used in the owner’s QBI calculation, so part of the federal SALT benefit may be offset by a smaller Section 199A deduction. The net result should be modeled, not assumed.
Is the owner credit always refundable?
No. State owner relief may be refundable, nonrefundable, carried forward, or provided as an income exclusion. Credit percentages and treatment of resident and nonresident owners vary by state.
Is PTET still useful after the SALT cap increased?
It can be, especially when an owner’s personal SALT taxes exceed the applicable cap or the higher cap is reduced by the income phaseout. But PTET can be neutral or harmful when owner credits are limited, QBI is reduced, cash timing is poor, or compliance costs consume the benefit.
