Purchased car in il in 2015 where to enter sales tax paid on il1040

[TomD8]

Enter sales tax information on your federal return, not on your state return.  Information on your federal return flows to your state return.

[LinaJ2018]

If you purchased a car in 2015, you can only deduct sales tax you paid on your 2015 tax return if you have filed one.  Do not include on your 2016 tax return.

If you filed your 2015 taxes with TurboTax, to amend, follow :

2015 Amendment

In the program, as you amend your return, by entering the information under the Federal Tax / Deductions and Credits / Estimated Taxes and Other Taxes Pay / Sales Tax section will flow to the state tax section to calculate your state taxes correctly.
