For homeowners who itemize on their federal return, property taxes are deductible — but only up to a limit that changed dramatically for 2026. Understanding the rules can save you thousands of dollars, and the recent expansion is the most significant property-tax-related federal change in years. This guide explains the new cap, who benefits, and how to use it.
The SALT Deduction Cap in 2026
The state and local tax (SALT) deduction lets itemizers subtract certain state and local taxes on Schedule A. Under the Tax Cuts and Jobs Act of 2017, the cap was frozen at $10,000 ($5,000 if married filing separately) from 2018 through 2025. That low cap hit homeowners in high-tax states especially hard, because their property and income taxes easily exceeded $10,000.
The One Big Beautiful Bill Act (OBBBA), signed in 2025, raised the cap to $40,400 for tax year 2026 for single, head-of-household, and married-filing-jointly filers ($20,200 for married-filing-separately). This is a major expansion — the cap was $10,000 as recently as 2025, so the increase is more than fourfold for joint filers.
Key 2026 figures (IRS):
- Maximum SALT deduction: $40,400 (MFJ/single/HOH)
- Phase-down begins at $505,000 modified AGI
- Phase-down: 30 cents per dollar of excess MAGI, floor of $10,000
- Cap reverts to $10,000 after tax year 2029 unless Congress acts
The expansion is temporary: unless Congress acts, the cap snaps back to $10,000 for tax year 2030. Plan your strategy with that sunset in mind.
What Counts Toward the SALT Cap?
The $40,400 limit is a combined ceiling covering:
- State and local income tax (or, if you elect, general sales tax — not both)
- State and local real estate (property) tax on your home and other real property
- State and local personal property tax (e.g., value-based vehicle registration fees)
Example: A homeowner who pays $12,000 in property tax and $30,000 in state income tax has $42,000 of SALT but can deduct only $40,400 in 2026. The excess $1,600 yields no federal benefit.
Who Benefits Most?
The expanded cap mainly helps upper-middle-income filers in high-tax states (California, New York, New Jersey, Connecticut, Illinois) with MAGI roughly $150,000–$505,000. Below that, many taxpayers already cleared the old $10,000 cap. Above ~$606,000 MAGI, the phase-down pushes the cap back to $10,000, erasing the benefit for the very highest earners. The phase-down is gradual: for every dollar of MAGI above $505,000, the cap drops by 30 cents, until it floors at $10,000.
Itemizing vs. Standard Deduction
The SALT deduction only helps if your total itemized deductions exceed the standard deduction. For 2026 the standard deduction is $32,200 (MFJ), $16,100 (single), $24,150 (HOH). If your SALT plus mortgage interest plus charitable gifts don't beat that, you take the standard deduction and get no SALT benefit. The higher cap pulls more homeowners over the itemization threshold, which is the main practical effect of the change — it makes itemizing worthwhile for many who previously took the standard deduction.
Timing & Escrow Notes
- You deduct taxes in the year paid to the government, not when you deposit into escrow.
- If your lender pays the taxing authority from escrow in December, that counts for that tax year.
- Prorated taxes paid at closing: only your ownership period's share is deductible by you; the seller's share is theirs.
- Prepaying next year's tax in December can be deducted in the current year only if the taxing authority actually assesses and accepts it that year, subject to IRS conditions.
State-Specific Impact
In a state like New Jersey or Illinois, a homeowner paying $15,000 in property tax and $20,000 in state income tax now deducts the full $35,000 — impossible under the old $10,000 cap. In a no-income-tax state like Texas or Florida, the property tax alone (often $5,000–$10,000) now fits comfortably, and a sales-tax election can add more. The expansion is broadly favorable but temporary, so consider accelerating deductible payments while the higher cap is in effect if it helps your situation.
Practical Planning Tips
- Run both the standard and itemized calculations before filing; the higher cap may flip the result.
- Keep records of property tax payments from your lender's annual escrow statement.
- If close to the phase-down threshold, model the impact with a tax professional.
- Remember the cap sunsets after 2029 — do not assume the higher limit is permanent in long-range planning.
Frequently Asked Questions
Is the higher cap permanent?
No. The OBBBA expansion is scheduled to revert to $10,000 after the 2029 tax year unless Congress extends it. Plan for the possibility that it sunsets.
Can I deduct property tax on a rental?
Rental and business real estate taxes are deducted as a business expense on Schedule E (or the relevant form), not on Schedule A, and are not subject to the SALT cap.
Should I prepay property tax to maximize the deduction?
Only if your locality assesses and accepts the payment in the current tax year, and only if you itemize. Consult a tax professional; prepayment strategies have specific IRS conditions.

Worked SALT Examples for 2026
Example A — New Jersey couple, MFJ, MAGI $250,000: $18,000 property tax + $22,000 state income tax = $40,000 SALT. Under the old $10,000 cap they deducted only $10,000. Under the 2026 $40,400 cap they deduct the full $40,000 — a $30,000 larger deduction, worth roughly $7,000–$11,000 in federal tax depending on bracket.
Example B — California homeowner, MFJ, MAGI $550,000: $14,000 property tax + $40,000 state income tax = $54,000 SALT. MAGI exceeds $505,000 by $45,000, so the cap drops by 30% × $45,000 = $13,500, from $40,400 to $26,900. They deduct $26,900, not the full $40,400.
Example C — Texas homeowner, MFJ, MAGI $120,000: $9,000 property tax, no income tax. They elect the sales-tax deduction instead, adding perhaps $1,500. Total SALT about $10,500 — above the old cap, fully allowed under the new one.
The Phase-Down, Step by Step
The phase-down is the part most filers miss. It works like this:
- Start with the $40,400 cap.
- Compute excess MAGI = your modified AGI minus $505,000 (if positive).
- Reduce the cap by 30 cents for each dollar of excess.
- Stop at a floor of $10,000 — the cap never goes below the pre-2026 level.
At MAGI of about $606,667 the cap hits the $10,000 floor. Between $505,000 and $606,667 the benefit shrinks gradually, so very high earners see little or no gain from the expansion. If your income is in that band, model the numbers carefully rather than assuming the higher cap applies.
Married Filing Separately
Married couples who file separately each get a $20,200 SALT cap (half of the joint figure). This matters because, under the old rules, filing separately often slashed the cap to $5,000 per spouse — a powerful reason to file jointly. With the expansion, the separate cap is $20,200, but filing jointly still allows the full $40,400 combined, so joint filing remains advantageous for most couples who itemize. Choose your filing status based on the whole return, not just SALT.

| $606,667 or above | $10,000 | Floor reached |
State Conformity and Surprises
A few states with their own "SALT" or itemized-deduction limitations can interact with the federal change, and some localities cap how much property tax they will levy. More importantly, the federal expansion is temporary: it sunsets after 2029. If you are modeling a multi-year tax plan, build a scenario with the cap returning to $10,000 to see how your after-tax cost changes. The difference can be thousands of dollars a year for high-tax-state homeowners, which affects decisions like whether to itemize, prepay, or even relocate.
Bottom Line
The 2026 SALT expansion to $40,400 is the biggest federal property-tax-related change in years, but it is temporary and income-phased. If you own in a high-tax state and itemize, the higher cap can cut your federal bill by thousands — provided your total itemized deductions beat the standard deduction. Track your MAGI against the $505,000 phase-down threshold, keep escrow records, and plan for the 2029 sunset. For the underlying rules, see the IRS Schedule A instructions.
Recordkeeping That Pays Off
Keep every property-tax record: your lender's annual escrow statement, any direct payments to the taxing authority, and receipts for special assessments. At filing time, these documents prove what you paid and when — essential if the IRS questions a deduction or if you prepaid. Store them with your tax return for at least three years. Good records are the difference between a smooth deduction and a disputed one.
Property Tax and the Mortgage-Interest Deduction
The SALT deduction works alongside — not instead of — the mortgage-interest deduction. A homeowner who itemizes can often deduct both: mortgage interest on up to $750,000 of acquisition debt (federal limit) and property tax up to the SALT cap. Together they can push total itemized deductions well above the standard deduction, especially in high-tax states. Model them together; optimizing one without the other can leave money on the table.
State-Level SALT Workarounds
A few states tried "workaround" entity-level taxes to let pass-through-business owners bypass the old SALT cap. With the federal cap now at $40,400, some of those workarounds are less valuable, and a few states have scaled them back. If you own an S-corp, partnership, or LLC that passes income through, ask your accountant whether a state workaround still helps in 2026 — the answer depends on your state and income.
Bottom-Line Checklist
- Confirm you itemize (beat the standard deduction).
- Add property tax + income/sales tax; cap at $40,400 (MFJ) or $20,200 (MFS).
- Watch MAGI near $505,000 for phase-down.
- Keep escrow and payment records.
- Plan for the 2029 sunset.
Closing Thought
The 2026 SALT expansion is a genuine but temporary gift to itemizers in high-tax states. Use it while it lasts: confirm you itemize, track your MAGI against the phase-down, and keep immaculate records. If your situation is complex — a pass-through business, a high-income year, or a planned move — a short conversation with a tax professional can be the difference between capturing the full benefit and leaving it on the table. The rules are clear, but the interactions with your other deductions are where the value hides.
