Deductions & credits

Yes. You are correct NeverRight. New York allows you to deduct union dues in full. TurboTax will add your union dues to Form IT-196, line 21 (unreimbursed employee expenses), but will subtract 2% of your New York income from your allowable deduction.

You can add the balance on line 44. You will need TurboTax CD/Download to make this entry.
