Sales tax is an itemized deduction which will have no effect at all on your tax due or refund unless you have enough other itemized deductions like mortgage interest, etc. to exceed your standard deduction. You can explore the sales tax deduction here:
Federal>Deductions and Credits>Estimates and Other Taxes Paid> Sales Tax.
Your itemized deductions have to be more than your standard deduction before you will see a change in your tax owed or tax refund. The deductions you enter do not necessarily count “dollar for dollar;” many of them are subject to meeting tough thresholds—medical expenses, for example, must meet a threshold that is pretty hard to reach. (Only the amount that is MORE than 7.5% of your AGI counts) The software program uses all the IRS rules that apply to the expenses you enter, and it tells you if you have enough to use your itemized deductions or if using the standard deduction is more advantageous for you. Under the new tax laws, some deductions have been capped—there is a $10,000 limit to the itemized deductions for state, local, property and sales taxes.
Your standard deduction lowers your taxable income. The standard deduction makes some of your income “tax free.” It is not a refund. You will see your standard or itemized deduction amount on line 12 of your 2023 Form 1040.
