PTET SALT Cap Workaround

Why PTET exists: the SALT cap, the $40,000 OBBBA bump, and the 2030 cliff

The Tax Cuts and Jobs Act of 2017 capped the individual itemized deduction for state and local taxes (income or sales, plus property) at $10,000 per return under IRC Section 164(b)(6). For a married couple in a high-tax state, $10,000 frequently does not even cover the property tax, let alone state income tax -- so the rest of their state tax burden became federally non-deductible.

OBBBA raised the cap to $40,000 for 2025 and indexes it modestly through 2029, then it reverts to $10,000 in 2030 and beyond. There is an important catch built into the higher cap: it phases down for high earners. Above $500,000 of modified AGI, the $40,000 cap is reduced (the excess SALT phases out back toward a $10,000 floor). So the filers most likely to have large pass-through income -- the ones for whom PTET matters most -- often do not get the full $40,000 anyway.

Crucially, the SALT cap is an individual-level limit. It does not restrict state income tax that a partnership or S-corp deducts as a business expense on its own return. That single distinction is the entire foundation of the PTET workaround: move the state income tax off the owner's Schedule A (capped) and onto the entity's Form 1065 or 1120-S (uncapped).

Because the cap is scheduled to fall back to $10,000 in 2030, PTET is a planning tool with a known shelf life. The strategy is most valuable in the 2025-2029 window for filers above the $500,000 phase-down, and becomes broadly valuable again for almost everyone in a tax state from 2030 if Congress does not act.

The $10,000 SALT cap (raised to $40,000 for 2025-2029 by OBBBA, phasing down above $500,000 of income, then reverting to $10,000 in 2030) limits individual Schedule A deductions but does not limit state income tax deducted at the entity level. (IRC §164(b)(6) (SALT cap); OBBBA SALT cap $40,000 for 2025-2029 with phase-down above $500,000 MAGI, reverting to $10,000 in 2030)

The core mechanism: the entity pays the tax, you take the credit

A PTET regime imposes a state income tax directly on the pass-through entity (partnership, S-corp, and in most states a multi-member LLC) instead of taxing only the owners on their share of state-source income. The mechanics are consistent across states even though the rates and forms differ:

1. The entity makes an annual election (in a handful of states it is mandatory) and pays state income tax on its distributive income at the entity level. 2. The owners still report their full share of pass-through income on their personal state return, but they receive a credit (or, in some states, an income exclusion or subtraction) for their share of the entity-level tax paid. 3. That credit is designed to roughly offset the personal state tax the owner would otherwise owe, so the owner's net state cash position is largely unchanged.

What changes is the federal picture. The entity deducts the PTET payment in computing its federal taxable income, so each owner's K-1 income arrives already reduced. The owner never has to claim the state income tax on Schedule A, so the SALT cap is simply never in play. You have converted a capped, often-wasted itemized deduction into a fully effective above-the-entity-line business deduction.

The entity elects to pay state income tax at the entity level and deducts it federally; owners report full income on the state return but claim a credit for their share of the PTET, leaving state cash roughly unchanged while federal taxable income falls. (State PTET statutes implementing IRS Notice 2020-75; IRC §702 (partner's distributive share); IRC §1366 (S-corp shareholder's pro-rata share))

IRS Notice 2020-75: the federal green light for 'Specified Income Tax Payments'

The reason PTET works -- and is not an aggressive gray-area maneuver -- is IRS Notice 2020-75, issued in November 2020. The Notice explicitly blesses the structure and supplies the operative term: a "Specified Income Tax Payment" is any amount a partnership or S-corp pays to a state, local government, or DC to satisfy its own income tax liability.

The Notice establishes three points that make the workaround bulletproof:

- The entity is allowed a federal deduction for these payments in computing its non-separately stated taxable income or loss in the year of payment (treated as an ordinary trade-or-business expense under IRC Section 162). - These payments are NOT taken into account in applying the $10,000 SALT deduction limit to any individual partner or shareholder. The cap simply does not reach them. - The treatment applies whether the tax is mandatory or elective, and whether or not the owners receive a credit, deduction, or other state benefit for their share.

Taxpayers were permitted to rely on Notice 2020-75 for PTE tax years ending after December 31, 2017, for payments made under state laws in effect by November 9, 2020. This Notice is the technical backbone that let more than three dozen states roll out PTET regimes with confidence. Treasury has not walked it back, and OBBBA did not disturb it.

IRS Notice 2020-75 confirms that state income tax paid by a partnership or S-corp on its own liability is a deductible business expense at the entity level and is not subject to the individual SALT cap, regardless of any owner-level credit. (IRS Notice 2020-75; IRC §162 (trade or business expenses); IRC §164(b)(6)(B) (SALT cap exception for entity-level tax))

The QBI haircut: PTET shrinks your §199A deduction dollar-for-dollar

This is the single most overlooked cost of PTET, and the reason a back-of-envelope "PTET times my marginal rate" estimate overstates the benefit. Because the PTET payment is deducted at the entity level, it reduces qualified business income (QBI) dollar-for-dollar. A lower QBI means a smaller 20% Section 199A deduction.

The trade-off, in plain numbers, for an owner in the 35% federal bracket who makes a $46,500 PTET payment: - Federal benefit: the $46,500 deduction saves $46,500 x 35% = $16,275 of federal income tax. - QBI cost: QBI falls by $46,500, so the 20% QBI deduction falls by $9,300, which at 35% costs $3,255 of additional tax. - Net federal benefit: $16,275 - $3,255 = roughly $13,020.

So the rule of thumb is not "PTET x marginal rate" but closer to "PTET x marginal rate x (1 - 20%)," i.e. PTET x 80% x marginal rate, for an owner who is getting the full QBI deduction. The haircut disappears for owners who get no QBI deduction anyway -- specified service businesses (SSTBs) fully phased out above the income thresholds, or businesses limited by the W-2 wage and UBIA tests -- in which case the benefit is the full PTET x marginal rate. The point is that you must model the QBI interaction, not assume it.

A PTET payment reduces qualified business income dollar-for-dollar, shrinking the 20% §199A QBI deduction. For an owner receiving the full QBI deduction, the net federal benefit is roughly PTET x 80% x marginal rate, not PTET x marginal rate. (IRC §199A (QBI deduction, made permanent by OBBBA); Notice 2020-75 (entity-level deduction reduces non-separately stated income))

State rate structures: flat, progressive, and top-rate models

PTET rates track each state's individual income tax and fall into three patterns. Knowing which one applies to you is the difference between a clean estimate and a surprise.

Flat rate on qualified net income. California charges a flat 9.3% of qualified net income for its elective PTE tax (available for tax years 2021 through 2025, with sunset-extension proposals pending). Illinois is 4.95%, Massachusetts 5%, Colorado 4.4%, Georgia 5.39%, Michigan 4.25%, Virginia 5.75%.

Progressive brackets. New Jersey's Business Alternative Income Tax (BAIT) runs from 5.675% on the first $250,000 up to 10.9% on distributive proceeds over $1 million. New York's PTET is progressive up to 10.9%, with a separate New York City PTET available on top.

Top-rate alignment. Many states (Arizona 2.5%, Arkansas 3.9%, North Carolina 4.5%, Ohio 3%, Oklahoma 4.75%, Minnesota 9.85%, and others) simply set the PTET at the state's top individual rate.

"Qualified net income" is generally the share of entity income allocable to owners who are eligible for the PTET credit and subject to that state's personal income tax -- so C-corp partners, tax-exempt owners, and (in some states) nonresidents may be excluded from the base. Run your own state's exact rate and base before relying on a generic figure; the TaxKiln PTET Analyzer carries the per-state rates.

PTET rates follow state individual rates in three patterns: flat (CA 9.3%), progressive (NJ 5.675%-10.9%, NY up to 10.9%), or top-individual-rate alignment. The base is generally the income allocable to credit-eligible owners. (State PTET enacting statutes (e.g. CA Rev. & Tax. Code §19900; NJ BAIT P.L. 2019 c.320); rates current for TY 2025/2026 elections)

Election timing, prepayments, and the deadlines that void the benefit

Almost every PTET is an annual election, not a one-time forever choice, and missing the mechanics can cost you the entire year's benefit. Two examples show how unforgiving this is:

California. A qualified entity elects annually on its timely filed original PTE return. But the credit hinges on a prepayment: by June 15 of the tax year the entity must pay the greater of $1,000 or 50% of the prior year's PTET. The remainder is due by the original return due date (generally March 15). If the June 15 prepayment is short, the owner's PTET credit (claimed on Form 3804-CR) can be reduced by 12.5% of the shortfall. Miss June 15 entirely and you can lose the election for the year.

New Jersey. The entity must register and file an annual BAIT election by the original due date of the BAIT return (the 15th day of the third month after year-end -- March 15 for calendar-year filers). The election cannot be made retroactively, and estimated BAIT payments follow the standard quarterly schedule.

The general rule across states: a missed election or missed minimum prepayment can mean complete loss of PTET eligibility for that year, and underpayment triggers normal state penalties and interest. Build the deadline into your tax calendar the way you would a quarterly estimate, and decide each year before the first prepayment date whether to elect.

PTET is an annual election with state-specific deadlines and prepayment rules. California requires a June 15 prepayment (greater of $1,000 or 50% of prior-year PTET) or the credit is haircut; New Jersey requires a non-retroactive election by the BAIT return due date. (CA Form 3804/3804-CR election and prepayment rules; NJ BAIT annual election by original return due date; state underpayment penalty statutes)

Who benefits, who does not, and the multi-state credit trap

PTET is not universally good. It helps most when: - You own a multi-owner partnership or S-corp in a high-tax state (CA, NY, NJ, MA, MN, OR), where combined effective rates on pass-through income are high. - Your Schedule A is already at or above the SALT cap, so you are losing the deduction anyway. - You are above the $500,000 OBBBA phase-down, where the $40,000 cap is shrinking.

It helps little or not at all when: - You are a sole proprietor or single-member disregarded LLC -- there is no separate "pass-through entity" to make the election. (Forming an S-corp can create eligibility, but only if the S-corp math otherwise works.) - You operate in a state with no income tax (TX, FL, WA, NV, etc.) or one that has not enacted a PTET (PA, DE, ME, VT, ND as of 2026). - The entity has C-corp or tax-exempt owners who cannot use the credit; electing can strand those owners.

The most expensive mistake is the multi-state resident-credit trap. If you are a resident of one state and your entity pays PTET to another, your home state may or may not give you a resident credit for the other state's PTET. Where it does not, you can be taxed twice on the same income. In multi-state structures, confirm the resident-credit interaction before electing, and coordinate which states the entity elects in. Other common errors: electing with large non-qualifying owners, ignoring basis and distribution effects of the entity-level payment, and failing to put an annual-decision and tax-distribution gross-up clause in the operating agreement.

PTET helps multi-owner partnerships and S-corps in high-tax states whose SALT cap is already exhausted, but not sole proprietors, no-income-tax states, or entities with non-qualifying owners. The key risk is a home state denying a resident credit for another state's PTET, causing double taxation. (State resident-credit statutes; IRC §1361 (S-corp eligible owners); Notice 2020-75 (election available 'whether or not' owners receive a credit))

Sizing the benefit and the 2030 planning horizon

The simplest way to size a PTET decision is to compare three numbers: the federal deduction benefit, the QBI haircut, and the SALT deduction you give up.

- Federal deduction benefit = PTET payment x your marginal federal rate. - QBI haircut = PTET payment x 20% x your marginal rate (zero if you get no QBI deduction). - SALT given up = the personal state income tax you would otherwise have deducted on Schedule A, but only up to the cap and only to the extent the cap was not already filled by property tax. For most high earners whose property tax alone exceeds the cap, this is zero -- they were getting no marginal benefit from the state income tax on Schedule A anyway.

Net federal benefit = federal deduction benefit - QBI haircut - SALT given up. The TaxKiln PTET Analyzer runs this netting per state.

The planning horizon matters. The OBBBA $40,000 cap (with its $500,000 phase-down) governs 2025 through 2029; in 2030 the cap is scheduled to revert to $10,000. So a high earner in a tax state who is above the phase-down today should be electing now, and essentially everyone in a tax state should re-run the math for 2030. State PTET regimes themselves are still moving -- California, Oregon, and Virginia have extended sunset dates, and a few states keep tweaking election mechanics -- so re-evaluate every year before the first prepayment deadline.

Net federal benefit equals the entity-level deduction benefit minus the QBI haircut minus any Schedule A SALT deduction actually given up. The OBBBA $40,000 cap window runs 2025-2029 before reverting to $10,000 in 2030, so the strategy has a defined planning horizon. (IRC §164(b)(6); IRC §199A; IRS Notice 2020-75; OBBBA SALT cap reversion to $10,000 in 2030)
