If you're self-employed, you can enter your union dues as
a Schedule C business expense.
Otherwise, if you're an employee, enter your union dues
as a job-related
expense. Simply search for union dues in your TurboTax program and then click the "Jump to"
link in the search results. We'll take you to a screen that asks about
your job-related expenses.
Continue following the on-screen instructions, and eventually
you'll come to the Job-Related Expenses screen.
Here's where you enter your union dues plus initiation fees. You can include
assessments for benefits paid to unemployed union members, but not the portion
that provides funds for sick, accident, or death benefits.
Note: Job-related
expenses (including union dues) are not fully deductible, as they are subject
to the 2% rule. More info
