If you aren't sure how much sales tax you actually paid this year, you can use the IRS Sales Tax Deduction Calculator or the State and Local General Sales Tax Deduction Worksheet in the Schedule A instructions, which you can find on the IRS website .
You can choose to deduct either the sales taxes paid during 2025 or the state income taxes withheld from your income during 2025. The state income taxes withheld from your W-2s and 1099s have already been included and don't need to be entered again.
Our software will use the greater of the sales taxes paid or the state income taxes withheld when figuring your itemized deductions.
