What is the SALT deduction cap in 2026?

The Big Beautiful Bill raised the SALT deduction cap to $40,400 for tax years 2025-2028, up from $10,000 under the original TCJA. For married filing separately, the cap is $20,200. The cap phases down for taxpayers with AGI above $500,000.

Who benefits from the higher SALT cap?

Homeowners in high-tax states like New York, New Jersey, California, Connecticut, Illinois, and Maryland benefit most. These taxpayers often pay $15,000-$40,000+ in combined state income and property taxes. The higher cap allows them to deduct more, but only if they itemize deductions.

Does the $40,400 cap phase down for high earners?

Yes. The SALT cap phases down from $40,400 toward $10,000 for taxpayers with AGI above $500,000 ($250,000 for married filing separately). The cap is reduced by $1 for every $20 of income above the threshold.

Should I itemize or take the standard deduction?

You should itemize only if your total itemized deductions (SALT + mortgage interest + charitable contributions + medical expenses + other) exceed the standard deduction: $15,700 for single filers or $31,400 for married filing jointly in 2026. The higher SALT cap makes itemizing worthwhile for more people.

How does the SALT deduction affect my federal taxes?

The SALT deduction reduces your taxable income. The tax savings equals your deductible SALT amount times your marginal federal tax rate. For example, if you deduct $30,000 in SALT at a 22% marginal rate, you save $6,600 in federal taxes.

Does my state affect the SALT deduction?

Absolutely. States with no income tax (Texas, Florida, Nevada, Washington) and low property taxes generate minimal SALT. States with high income tax rates (California, New York, New Jersey) and high property taxes generate SALT that far exceeds the old $10,000 cap.

Can I deduct sales tax instead of state income tax?

Yes. You can choose to deduct either state and local income taxes OR state and local sales taxes (not both). This option is primarily useful for residents of states with no income tax who pay significant sales taxes.

What happened to the SALT cap before the Big Beautiful Bill?

The TCJA (2017) imposed a $10,000 cap on SALT deductions for tax years 2018-2025. If the TCJA had expired, the cap would have been removed entirely. Instead, the Big Beautiful Bill extended the TCJA but raised the SALT cap to $40,400 as a compromise.

Is the $40,400 SALT cap permanent?

No. The Big Beautiful Bill's $40,400 cap applies to tax years 2025 through 2028. After 2028, Congress will need to act again — the cap could revert to $10,000, be eliminated, or be set at a different level.

How does property tax fit into the SALT deduction?

Property taxes paid to state and local governments are included in SALT. For many homeowners, property tax alone can exceed $10,000 — meaning the old cap left no room for state income tax deductions. The higher cap addresses this issue.

How does this calculator estimate my state income tax?

We use your state's average effective income tax rate applied to your gross income. This is an approximation — your actual state tax depends on state-specific brackets, deductions, and credits. You can override this with your actual state tax amount in the refinement section.

SALT Deduction Calculator: How Much Do You Save?

The Big Beautiful Bill quadrupled the SALT deduction cap from $10,000 to $40,400. For a homeowner in New York paying $22,000 in combined state income and property taxes, that’s up to $12,000 in SALT that was previously non-deductible — worth roughly $2,600 in federal tax savings at the 22% bracket.

The SALT deduction matters because it changes how much double-tax pressure households feel from federal tax on top of high state and local tax bills. For some homeowners, the cap is mostly irrelevant. For others, it can swing federal taxes by thousands of dollars.

That makes SALT a classic policy-risk issue. The same household can look meaningfully more or less tax-efficient depending on where the deduction cap lands and whether itemizing still makes sense.

The Big Beautiful Bill raised the SALT deduction cap from $10,000 to $40,400 — a game-changer for homeowners in high-tax states. Enter your details to see how much more you can deduct and what it saves you in federal taxes.

SALT Deduction Calculator: The Short Answer

The SALT deduction lets you subtract some combination of state income, state sales, and local property taxes from federal taxable income if you itemize. The practical value depends on three things: how much SALT you pay, where the cap is set, and whether your total itemized deductions exceed the standard deduction.

What Is the SALT Deduction?

SALT stands for State and Local Taxes. The SALT deduction allows you to deduct the state income taxes (or state sales taxes) and local property taxes you pay from your federal taxable income — but only if you itemize deductions instead of taking the standard deduction.

Before the TCJA in 2018, there was no cap on SALT deductions. The TCJA imposed a $10,000 cap ($5,000 for married filing separately), which hit high-tax states especially hard. The Big Beautiful Bill raised this cap (from a $40,000 2025 base) to $40,400 in 2026.

Who Benefits from the Higher Cap?

The $40,400 cap primarily benefits:

Homeowners in high-tax states (NY, NJ, CA, CT, IL, MD) who pay significant property taxes plus state income tax
Higher earners who already itemize — the benefit only applies if your total itemized deductions exceed the standard deduction ($32,200 MFJ in 2026)
Dual-income households where combined state taxes and property taxes easily exceed $10,000

People in states with no income tax (TX, FL, NV, WA, WY, SD, AK, NH, TN) and modest property taxes typically see no benefit, since their total SALT falls below even the old $10,000 cap.

Why The Cap Creates Geographic Policy Risk

SALT is one of the clearest examples of federal tax policy landing differently by geography. A rule written in Washington can feel minor in a low-tax state and very expensive in a high-tax state. That is why the cap became such a major issue for households in places with high property taxes and meaningful state income taxes.

The Phase-Down for High Earners

The 2026 $40,400 cap phases down for taxpayers with AGI above $505,000 ($252,500 for married filing separately). The cap is reduced by 30% of AGI above that threshold, eventually flooring at the old $10,000 cap. At 2026 values, full phase-out to the floor happens around $606,333 of AGI for single/MFJ filers.

SALT vs. Standard Deduction

Remember: the SALT deduction only matters if you itemize. The 2026 standard deduction is $16,100 (single) or $32,200 (married filing jointly). You should itemize only if your total itemized deductions (SALT + mortgage interest + charitable contributions + other) exceed the standard deduction. The higher SALT cap makes itemizing worthwhile for more people, but many households will still come out ahead with the standard deduction.

SALT also lets you deduct either state income taxor state sales tax (not both), plus property tax. If you live in a no-income-tax state, your sales-tax election can be the bigger driver.

Business Owners: PTET Workaround Still Matters

The OBBBA SALT cap changes do not eliminate the pass-through entity tax (PTET) strategy used in many states. Owners of S-corps and partnerships may still be able to pay state taxes at the entity level and bypass the individual SALT cap. This is technical and state-specific, so review it with a qualified tax professional.

Important Timing Risk: 2030 Reversion

Under current law, the higher SALT cap is temporary and reverts to the original $10,000 level in 2030. If your housing or relocation decisions depend on today’s higher cap, model both scenarios.

What To Watch Next

For most households, the key question is not whether the SALT deduction exists. It is whether future tax legislation changes the cap, restores a tighter limit, or lets other expiring provisions reshape the itemize versus standard-deduction decision. This page helps you see that exposure in dollars instead of headlines.

Why SALT Still Matters Even If You Do Not Itemize Today

A household can move from not itemizing to itemizing as income, mortgage interest, charitable giving, or state-local tax burdens change. That means SALT policy can matter before it appears on your current return. The strategic value is in knowing when the threshold is getting close.
