What is the SALT deduction cap for 2026?

The SALT (state and local tax) deduction cap for 2026 is $40,000 for married filing jointly and $20,000 for single filers, up from $10,000 for all filers under the original TCJA. Married filing separately filers have a $20,000 cap. The increase was enacted through the One Big Beautiful Bill Act. The cap covers the combined total of state income tax (or sales tax), local income tax, and property tax deductions on Schedule A.

Did the SALT cap expire in 2026?

The original $10,000 SALT cap from the TCJA was set to expire December 31, 2025, which would have made the SALT deduction unlimited again. However, the One Big Beautiful Bill Act replaced it with a new $40,000 cap for 2026 and beyond. So the deduction is not uncapped — but the limit is four times higher than it was from 2018 to 2025.

Which states benefit most from the SALT deduction increase?

States with the highest combined state income tax and property tax burdens benefit most. New York, New Jersey, Connecticut, California, Illinois, and Maryland top the list. In New Jersey, for example, the average homeowner pays over $9,000 in property tax alone, and state income tax can easily add another $5,000-$15,000 depending on income. The jump from a $10,000 to $40,000 cap means these filers can now deduct most or all of their state and local taxes.

Should I itemize deductions in 2026 because of the SALT cap increase?

It depends on your total itemized deductions. The 2026 standard deduction is $15,000 (single) or $30,000 (married filing jointly). You should only itemize if your combined SALT, mortgage interest, charitable contributions, and other deductions exceed those amounts. With the higher $40,000 SALT cap, more high-tax-state residents will now find itemizing worthwhile — particularly married homeowners in New York, New Jersey, and California with significant property taxes and state income tax.

SALT Deduction 2026: The Cap, the Workarounds, and Who Actually Benefits

What the SALT Deduction Actually Is

SALT stands for state and local taxes. When you file your federal return and choose to itemize deductions (instead of taking the standard deduction), you can deduct three categories of state and local taxes from your federal taxable income:

State income tax (or state sales tax — you pick one, not both)
Local income tax (if your city levies one — looking at you, New York City)
Property tax on your home

Before 2018, there was no cap. You could deduct every dollar of state and local tax you paid. A homeowner in Bergen County, New Jersey, paying $14,000 in property tax and $8,000 in state income tax could deduct all $22,000. Simple.

Then the TCJA happened.

The $10,000 Cap: 2018–2025

The Tax Cuts and Jobs Act capped the SALT deduction at $10,000 total ($5,000 for married filing separately). That same New Jersey homeowner with $22,000 in state and local taxes? They could only deduct $10,000. The other $12,000? Tough luck.

This hit high-tax blue states disproportionately hard. It wasn't subtle, and it wasn't accidental. The cap raised an estimated $670 billion over ten years according to the Joint Committee on Taxation, and the revenue came overwhelmingly from residents of New York, New Jersey, California, Connecticut, Illinois, and Maryland.

The political fallout was immediate. GOP House members from these states nearly lost their seats over it. Several did. It became the most relitigated provision in the entire TCJA.

What Happened in 2026: The $40,000 Cap

Here's where it gets interesting. The TCJA's SALT cap was set to expire on December 31, 2025. Without any new legislation, the deduction would have become unlimited again starting in 2026. Back to the good old days of deducting every dollar.

But the One Big Beautiful Bill Act didn't let it expire cleanly. Instead of removing the cap entirely, Congress raised it to $40,000. The compromise was driven by Republican members from high-tax states who demanded relief but couldn't push for a fully uncapped deduction without blowing up the bill's revenue projections.

So the 2026 rules are:

$40,000 cap for married filing jointly
$20,000 cap for single filers and married filing separately
The cap applies to the combined total of state income/sales tax + local income tax + property tax
There's an income-based phase-down for very high earners (details below)

Who Benefits Most: State-by-State Breakdown

The SALT cap increase matters a lot in some states and literally not at all in others. If you live in Texas, Florida, or Wyoming — states with no income tax — your SALT deduction is just property tax. Most people in those states were under $10,000 anyway.

But in high-tax states? This is a meaningful tax cut.

State	Avg. Property Tax	Top State Rate	Typical SALT at $150K Income	Hit Old $10K Cap?	Hit New $40K Cap?
New Jersey	$9,300	10.75%	~$19,300	Yes	No
New York	$6,800	10.9%	~$17,800	Yes	No
Connecticut	$7,400	6.99%	~$15,900	Yes	No
California	$4,300	13.3%	~$16,800	Yes	No
Illinois	$5,100	4.95%	~$12,500	Yes	No
Maryland	$3,600	5.75% + local	~$13,100	Yes	No
Texas	$4,100	0%	~$4,100	No	No
Florida	$2,800	0%	~$2,800	No	No

The pattern is clear. If your state has both an income tax and high property taxes, you were getting squeezed by the $10,000 cap. The $40,000 cap fixes that for the vast majority of filers in those states.

The Real Dollar Impact

Let's run specific scenarios. Married couple, homeowners, standard assumptions.

Scenario	SALT Paid	Deductible (Old $10K Cap)	Deductible (New $40K Cap)	Extra Deduction	Tax Savings*
NJ, $150K income	$19,300	$10,000	$19,300	$9,300	~$2,046
NY, $200K income	$24,600	$10,000	$24,600	$14,600	~$3,504
CA, $300K income	$35,200	$10,000	$35,200	$25,200	~$8,064
TX, $150K income	$4,100	$4,100	$4,100	$0	$0

*Tax savings assume filer is itemizing and applied at their marginal federal rate (22%–32% depending on income).

That California family at $300K income saves over $8,000 a year from this one change. The Texas family? Zero impact. They were never capped.

SALT Cap vs. Standard Deduction: The Math You Should Actually Do

Here's what a lot of articles get wrong: the SALT cap increase doesn't help you at all if you take the standard deduction. And most people do.

The 2026 standard deduction is $30,000 for married filing jointly. To benefit from the higher SALT cap, your total itemized deductions need to exceed $30,000. SALT is usually the biggest piece, but you also need to add mortgage interest and charitable contributions.

Quick example: A married couple in New Jersey with $19,000 in SALT, $12,000 in mortgage interest, and $2,000 in charitable giving has $33,000 in itemized deductions. That beats the $30,000 standard deduction by $3,000. At a 22% marginal rate, that's $660. Worth it, but not life-changing.

Under the old $10,000 cap, that same couple had $10,000 + $12,000 + $2,000 = $24,000 in itemized deductions — below the standard deduction. They couldn't itemize at all. Now they can. That's the shift.

The Pass-Through Entity Workaround

There's a loophole — or "workaround" if you want to be polite about it — that's still alive in 2026.

Over 30 states now offer a pass-through entity (PTE) tax election. Here's how it works: instead of the business owner paying state income tax personally (where it's subject to the SALT cap), the S-corp or partnership pays state tax at the entity level. The entity-level tax payment is fully deductible on the federal return because it's a business expense, not a personal SALT deduction. No cap applies.

The IRS blessed this with Notice 2020-75. It's not going away.

With the SALT cap now at $40,000, the PTE workaround matters less for moderate earners. But for business owners with very high state tax bills — say, a California LLC owner paying $80,000 in state income tax — the PTE election can still save thousands in federal tax that even the $40,000 cap doesn't cover.

How Other Countries Handle This

The whole concept of a SALT deduction is a quirk of American federalism. Most countries we cover at FiscalFold don't have significant sub-national income taxes, so the question doesn't arise.

Canada: Provincial income taxes are separate but there's no federal deduction for them. They're just... additional tax. You pay both.
Germany: The Solidaritätszuschlag is a federal surcharge, not a state tax. Church tax is deductible, but Länder don't levy separate income taxes on individuals.
UK: No sub-national income taxes at all. Scotland has its own rate bands but it's still collected federally through HMRC.
Spain: Regional communities set their own rates, but there's no federal deduction for the regional portion.

The American system of federally deducting state taxes is unusual. It creates exactly the kind of political fights we saw with the SALT cap. See how total tax burdens compare across countries with our comparison tool.

The Bottom Line

The SALT cap went from $10,000 to $40,000. If you live in a high-tax state and were getting squeezed — you just got meaningful relief. If you live in a no-income-tax state, this changes nothing for you. And if you're a high-income business owner in a high-tax state, the PTE workaround is still your best friend.

The big question: does this make itemizing worthwhile for you? Run the math. If your SALT + mortgage interest + charitable contributions exceed $15,000 (single) or $30,000 (married), you should itemize. If not, the standard deduction still wins.
