Can You Deduct Sales Tax on Schedule A? Tables, Receipts, SALT Cap

Yes. If you itemize, you can deduct sales tax on Schedule A by electing to claim state and local general sales taxes in place of state and local income taxes on Line 5a. You can’t take both in the same year, and the choice applies only to the current tax year, so you can switch methods from one year to the next.¹

When the Sales Tax Election Beats the Income Tax Election

The sales tax option almost always wins if you live in one of the nine states with no personal income tax. There’s nothing to claim on the income side, so sales tax is your only route to a SALT deduction beyond property taxes.

Even in states that do collect income tax, sales tax can come out ahead in a year when you made a large purchase. If the sales tax on a new vehicle alone exceeds what your state withheld from your paycheck, the election pays for itself.

Before running either calculation, check it against the standard deduction. For 2026, the standard deduction is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household.² Itemizing helps only if your SALT deduction plus mortgage interest, charitable contributions, and other eligible expenses together exceed those amounts.

Two Ways to Calculate the Deduction

You have two methods: total up every dollar of sales tax you actually paid during the year, or use the IRS optional sales tax tables that estimate a reasonable amount based on your income, state, and household size.³ Most filers use the tables, because keeping a year of receipts for every routine purchase isn’t practical.

The IRS Tables

The tables estimate what a typical household at your income level pays in your state, then adjust for family size. Income for this purpose is your adjusted gross income plus certain nontaxable items: tax-exempt interest, veterans’ benefits, nontaxable Social Security, and workers’ compensation.³ Family size includes you, your spouse if filing jointly, and every dependent on the return.

If your city or county levies its own sales tax on top of the state rate, the Schedule A worksheet builds in a local adjustment. If you moved during the year, the instructions include a proration method.

The simplest path is the IRS Sales Tax Deduction Calculator. You enter your ZIP code, income, family size, and any major purchases, and it produces the deduction amount.⁴

Actual Receipts

If you believe your real spending significantly exceeded the table estimate, you can total the sales tax on every purchase and deduct that number instead. The payoff can be a larger deduction, but you need to be able to document every dollar if the IRS asks. Very few filers go this route.

Major Purchases You Can Add on Top

The tables intentionally exclude large, irregular purchases. To keep filers from claiming the table amount in ordinary years and jumping to actual receipts in big-purchase years, the law lets you use the table and add the actual sales tax paid on certain specified items.⁴

Motor vehicles, including cars, trucks, RVs, and motorcycles. If the vehicle sales tax rate was lower than the general rate, you deduct what you actually paid. If it was higher, you deduct only what would have applied at the general rate.³
Boats and aircraft, if taxed at the general sales tax rate.
Mobile or manufactured homes, on the same general-rate condition.
Building materials for a major renovation or substantial addition to your home, if you paid the general rate on the materials.¹

The math is simple. If the tables give you $850 and you paid $2,400 in sales tax on a truck, your Line 5a entry is $3,250. That combination captures both routine spending and the one-time hit without asking you to keep receipts for groceries and shoes.

What Doesn’t Count

The statute defines a general sales tax as a tax imposed at a single rate on a broad range of retail goods.¹ Excise taxes on gasoline, tobacco, and alcohol are selective, not general, and don’t count no matter how much you paid.

The same limit applies to any item taxed above your state’s general rate. If a luxury surcharge pushes the rate higher on certain goods, only the portion equal to the general rate is deductible. Lower rates on food, clothing, medical supplies, and motor vehicles work the other way: those carve-outs don’t disqualify the rest of your state’s tax from counting as a general one.¹

Compensating use taxes do qualify. If you bought something from out of state and your home state charged a use tax on it, that tax counts the same as a general sales tax for this deduction.¹

The 2026 SALT Cap

For 2026, the total state and local tax deduction is capped at $40,400, or $20,200 for married filing separately.¹ That cap covers all your state and local taxes combined: your sales tax on Line 5a, real estate taxes on Line 5b, and personal property taxes on Line 5c. If the three together exceed $40,400, you can deduct only $40,400.

A phaseout kicks in at higher incomes. If your adjusted gross income exceeds $500,000 ($250,000 for married filing separately), the higher cap begins shrinking back toward $10,000, and the Schedule A instructions walk through that calculation.⁵ Below that threshold, the full $40,400 applies.

Reporting It on Schedule A

Once you’ve calculated the number, the reporting is simple. Lines 5a through 5e handle the entire SALT section.

Line 5a: your total sales tax deduction, meaning the table amount plus any major purchases, or your actual tracked total. Check the box on this line to elect sales taxes instead of income taxes.⁵
Line 5b: state and local real estate taxes.
Line 5c: state and local personal property taxes.
Line 5d: the sum of Lines 5a through 5c.
Line 5e: the smaller of Line 5d or your SALT cap. Above the income phaseout, the instructions send you to an additional worksheet.³

Checking the box on Line 5a is the formal election. Miss it, and the IRS treats your Line 5a figure as income taxes, which can cut your deduction or create a mismatch with state records.

Records to Keep

Under the table method, your documentation is modest: your ZIP code, income figures, household size, and receipts for anything you added as a major purchase. Under the actual-receipts method, you need the full set of receipts. Either way, hold on to dealer invoices, sales contracts, and closing documents for big-ticket items, since those show the exact tax paid.

The IRS generally requires you to keep records supporting a deduction for at least three years from the date you filed the return, or two years from the date you paid the tax, whichever is later.⁶ Three years is the standard window most filers plan around.
