Can You Deduct Sales Tax in Texas? SALT Cap and Methods

Yes, you can deduct sales tax in Texas on your federal return. Because Texas has no personal income tax, sales tax is the only state-level tax available to claim, and you take it on Schedule A of Form 1040. That means it only helps if you itemize, and itemizing only pays off when your total deductions exceed the standard deduction: $16,100 for single filers and $32,200 for married couples filing jointly in 2026.¹

Federal law lets a taxpayer deduct either state and local income taxes or state and local general sales taxes, not both.² With no Texas income tax to compare against, the choice makes itself: you check the sales tax box on Schedule A.

Will Itemizing Actually Help You

The sales tax write-off lives on Schedule A, so it does nothing for filers who take the standard deduction. For 2026 the standard deduction is:¹

Single or married filing separately: $16,100
Married filing jointly: $32,200
Head of household: $24,150

For most Texas homeowners, property tax and mortgage interest already push them close to or past those thresholds, and the sales tax deduction stacks on top. If you rent, have no mortgage, and give modestly to charity, the standard deduction almost certainly wins and you can skip the rest of this.

Two Ways to Calculate What You Can Deduct

The IRS offers two methods. Use whichever produces the bigger number, but you cannot blend them for the base calculation.³

The IRS Table Method

Each year the IRS publishes optional sales tax tables in the Schedule A instructions. You look up the row matching your adjusted gross income and number of exemptions, and the table returns a pre-calculated deduction based on average spending at your income level and your state’s tax rates.⁴ This is the easy path and the one most filers take.

Texas localities can add up to 2% on top of the 6.25% state rate, taking the combined rate as high as 8.25%.⁵ If your local combined rate exceeds the rate baked into the Texas table, the worksheet in the Schedule A instructions lets you adjust the table amount upward using a ratio.

The Actual Expense Method

You can also total up every dollar of general sales tax you actually paid during the year. This usually produces a larger deduction for anyone who spent heavily on taxable goods, but it requires receipts for everything you claim. If the IRS asks for proof, you need the actual receipts or invoices showing sales tax paid.³

Only general sales tax counts. Excise taxes, selective taxes on specific goods like tobacco or alcohol at rates higher than the general rate, and fees that are not true sales taxes do not qualify.² The IRS Sales Tax Deduction Calculator on irs.gov will run both methods for you.

Adding Sales Tax on Major Purchases

Whichever base method you choose, you can add the sales tax paid on certain big-ticket items on top.⁴ Qualifying purchases include:

Motor vehicles: cars, trucks, motorcycles, motor homes, recreational vehicles, and off-road vehicles. Leased vehicles count.
Boats and aircraft.
Homes, including mobile and prefabricated homes.
Home improvements: sales tax on materials for a substantial addition or major renovation.

The tax on these items is added dollar-for-dollar, with one limit for motor vehicles: if the vehicle tax rate exceeds the general sales tax rate, you can only deduct what the general rate would have produced.² In Texas the motor vehicle rate is 6.25%, matching the state general rate, so this limit rarely bites Texas buyers.⁶

Hold onto the purchase contracts and closing documents. A $50,000 truck generates roughly $3,125 in deductible Texas sales tax, enough that the IRS may ask to see documentation.

Online and Out-of-State Purchases

If you buy something from an out-of-state seller and pay Texas use tax rather than sales tax, that use tax is deductible as a general sales tax. Federal law treats a compensating use tax the same as a general sales tax, provided it applies to the use or consumption of an item and complements the state’s general sales tax.² That covers typical online or cross-border purchases where you owe Texas use tax.

The SALT Cap for 2026

Your total deduction for state and local taxes is capped, with property tax plus either income or sales tax rolled into one limit. For 2025 the One Big Beautiful Bill Act raised the cap from $10,000 to $40,000 ($20,000 for married filing separately), and for 2026 the cap rises 1% to $40,400.⁷

For most Texas filers the new cap is generous enough not to matter. Your combined property tax and sales tax deduction would have to clear $40,400 before the cap kicks in. If you own expensive property in a high-tax jurisdiction like parts of Harris County or Dallas County, run the numbers.

There is also an income-based phaseout. If your modified adjusted gross income exceeds roughly $505,000 in 2026 ($252,500 for married filing separately), the cap begins to shrink. The reduction equals 30% of the amount your income exceeds the threshold, and the cap cannot fall below $10,000. High earners still get a SALT deduction, just a smaller one.

One boundary worth noting: if you fall into the alternative minimum tax, the SALT deduction disappears from the AMT calculation entirely. Most filers never trigger AMT because the exemption is high, but anyone with large income and a sizable SALT deduction should check before counting on the full benefit.

Groceries, Prescriptions, and What Texas Does Not Tax

Texas exempts most groceries, including meat, produce, dairy, and bread. Prescription medications are also exempt. Two households with identical incomes can end up with very different deductible sales tax amounts depending on what they buy. The IRS tables already account for these exemptions when figuring the Texas average, and the actual expense method handles it naturally because no sales tax appears on the receipt.

If You Moved During the Year

If you moved between Texas cities or counties and crossed a local tax jurisdiction boundary, even within the same ZIP code, the IRS wants each residence counted separately. The Sales Tax Deduction Calculator on irs.gov lets you enter multiple addresses and figures the correct amount by how long you lived in each.⁴ A move within the same local taxing jurisdiction needs no adjustment.

Moving into or out of Texas is more involved. If you lived part of the year in an income-tax state and part in Texas, you can still elect the sales tax deduction, but the election applies to the whole return. You cannot deduct income taxes for the months in one state and sales taxes for the months in Texas. You pick one method for the full year, and the IRS table or calculator prorates based on days of residency.

Records to Keep

The table method is light on paperwork. Keep a record of your adjusted gross income and the receipts for any major purchases you added on top, and you are covered. The actual expense method is heavier: you need receipts, invoices, or bank statements showing every sales tax payment you claim.

The IRS can audit a return for three years after filing in most cases, and six years if you underreport income by more than 25% of your gross income.⁸ Keep sales tax records at least three years after filing, and six if you claimed a deduction that looks large relative to your income. If your documentation has gaps and your claimed amount looks implausible, the IRS will disallow the deduction and bill you for the back taxes plus interest.
