Standard Deduction

[BobRa]

If taking the Standard Deduction can i also use 2021 car purchase taxes

[Texas Roger]

No. Sales taxes paid on a car purchase can only be deducted when using itemized deductions and only then when you deduct sales taxes instead of state and local income tax.

No that is only if you itemize.  

If you itemize your deductions you can either take the state and local SALES TAX deduction OR the state and local INCOME TAX deduction whichever is greater. There are a couple items like car sales tax you can add to the general sales tax table.  That is mainly for people who live in a state without a state income tax.
