Why the bigger SALT cap is no reason to drop PTET

Jun 2026 · 6 min read

Most partnership and S-corp owners heard one headline: the federal SALT cap jumped from $10,000 to $40,400 for 2026. A lot of them quietly concluded the pass-through entity tax was no longer worth the trouble. That conclusion is wrong often enough to be expensive. The cap rose, but OBBBA left the PTET workaround in place, which means the keep-or-drop decision is live again for 2026, and it has a hard deadline.

The trigger is the calendar. The window is the first quarter of your tax year. In New York, for example, the election locks once your first estimated PTET payment is funded, and other states set their own timing, so check yours. Either way, the analysis has to happen before you wire money to the state, not after.

What PTET actually does

When your partnership or S-corp earns income, it passes through to your personal return, and the state tax on it lands on Schedule A, where SALT is capped. Anything over the cap is dead weight: you paid it, you get no federal deduction.

A PTET election rearranges that. The entity pays the state income tax directly and deducts it at the entity level, which is not subject to the SALT cap (the IRS blessed this in Notice 2020-75). That lowers the income passed through to you. You then generally get something back at the state level, a credit or deduction for your share of the entity-paid tax. The deduction moves from a capped line on your return to an uncapped line on the entity's. That is the whole trick.

The part that surprises people

PTET isn't only for people slammed by the cap. Because the entity pays and deducts the state tax, it passes through less income to you, which can lower your federal taxable income even in a year the cap isn't your binding limit. Whether that nets out to real savings depends on your state's credit and the specifics of your return, so it is a model-it question, not an automatic win. Be wary of blanket promises that PTET unlocks the standard deduction or shrinks self-employment tax; those turn on facts that do not hold for everyone.

When the cap does bite

The example: a pass-through owner with $560,000 of modified AGI, a 35% federal bracket, $40,000 of state income tax on the business income, and $10,000 of property tax

That is $50,000 of state and local tax in total, and $560,000 sits $55,000 over the $505,000 phasedown line, which is what shrinks the cap below.


2026 SALT cap is $40,400, phased down above $505,000 of modified AGI:
$55,000 over the line x 30% = $16,500 cut -> usable cap $23,900

Personal path: $23,900 x 35%	~$8,365($26,100 of the $50k just vanishes)
PTET path:
entity deducts the $40,000 (not capped): $40,000 x 35%	$14,000
+ $10,000 property tax under the $23,900 cap: x 35%	$3,500

total	~$17,500(~$9,135 better)
...minus the state credit haircut: if your state credits only 90% of the entity tax, you lose $4,000 -> ~$5,135 net

That credit haircut is decisive. A full-credit state keeps the whole delta; a partial-credit state can shrink it, and in tight cases flip PTET to value-negative. So the net-of-credit number is the one that matters, not the federal benefit alone.

Which band are you in

The decision tracks your modified AGI (the figure the SALT phasedown uses):

2026 modified AGI	Your SALT cap	The PTET call
Below $505,000	full $40,400	maybe drop, unless a state-specific or QBI factor applies
$505,000 to ~$606,333	phasing down toward $10,000	usually still worth it; run the exact math
Above ~$606,333	back to $10,000	keep it; the value is about what it was pre-OBBBA

There is a quieter reason to act in the phasedown band. Filers there get only a partial SALT deduction on the regular return, and for AMT they must add back what they did deduct, because Schedule A state and local taxes are not allowed against AMT income. That can trigger AMT and erase the partial benefit. PTET can help here, since an entity-level deduction is not a Schedule A SALT item and so does not create that add-back, but treat it as a reason to run the AMT math, not an automatic escape.

The honest caveats

Two things no straight version of this skips. First, Notice 2020-75 is a notice, not a final regulation; owners have relied on it for years while the promised regs stay unissued. Second, state law is neither uniform nor static. Each state decides whether its credit offsets your liability correctly, and some are still conforming to OBBBA. Sunsets move. Confirm your own state's current rules and credit percentage before you elect.

S-corp owners have an extra constraint: reasonable compensation governs. Set wages too high and you erode both the QBI deduction and the PTET benefit; too low and you invite reclassification. That is a comp conversation, not just a return.

Getting it done

We run the keep-or-drop model: your modified-AGI band, full SALT liability, the reduced-cap math, the QBI interaction, and the net-of-credit value, against your projected 2026 modified AGI, your K-1 income, the state tax attributable to the entity, and your other Schedule A items. State conformity and the exact credit percentage get confirmed against your state's revenue guidance. And the election itself is filed by the entity's authorized person (in New York, for instance, only an authorized person of the entity can make the election), which is why a documented keep-or-drop decision has to exist before that first estimated payment.

Which band you land in, the state tax your entity actually pays, and your state's credit percentage decide the call, and the deadline is your first 2026 estimated payment, after which the year is locked. A Diagnostic is where we surface which band you are in and whether to keep, drop, or model the middle. Running the model and making the election with your entity is the work we do for our clients.
