Sales tax paid on new car in Wisconsin

You can enter the sales tax you paid for the car you purchased in 2016 by going to Federal>Deductions and Credits>Estimates and Other Taxes Paid> Sales Tax.  You will be asked if you paid sales tax on a major purchase, and you will be able to enter the sales tax you paid for your new vehicle. 

Sales tax is an itemized deduction.  If your state has a state income tax, you have to choose between using the deduction for your state tax paid OR the sales tax deduction, whichever is higher.  The TT process will suggest one or the other as you prepare your return.

Is this still relevant for the 2022 tax deduction in Wisconsin?

Yes, I haven't seen any updates to the contrary. You may claim a sales tax for your new car in Wisconsin only if your total sales tax deduction is more than the state income taxes and you are itemizing instead of taking the standard deduction.
