Fact Sheet
Tax Deductibility
Union dues are tax-deductible. Here’s how to claim.
Union dues are fully tax-deductible. The deduction reduces your taxable income, so your saving equals the fee times your marginal tax rate. For someone in the $45,001 to $135,000 bracket (a 30% marginal rate in 2025-26), a $500 membership reduces tax by about $150, an effective cost of around $350. Your exact saving depends on your income.
