As an UFF-UNF member, your dues are typically deducted from your paycheck and are considered after-tax deductions, meaning tax is withheld from your paycheck before your dues are paid.
Please consult with the IRS and your tax specialist to find out about the union dues tax deduction.
Note: Union dues may only be deductible if you itemize on Schedule A, but not if you take the standard deduction. To find out if you qualify for a deduction, you need to calculate your AGI (Adjusted Gross Income), as well as all unreimbursed employee expenses (see link). Your union dues may be considered part of these “unreimbursed employee expenses.”
