Can I deduct union dues on my Canadian taxes?

Yes, union dues are fully deductible on your Canadian tax return. They reduce your taxable income, and the amount appears in Box 44 of your T4 slip.

Where do union dues appear on a T4?

Union dues appear in Box 44 of your T4 slip. This amount is automatically reported by your employer and includes annual dues paid through payroll deductions.

How much tax do I get back from union dues?

You get back your union dues multiplied by your marginal tax rate. For example, if you paid $800 in union dues and your marginal rate is 30%, you''d save $240 in taxes.

Are professional association fees deductible like union dues?

Yes. Annual professional membership fees required to maintain a professional status recognized by law (e.g., CPA, P.Eng, nursing college) are deductible on Line 21200, the same line as union dues. Initiation fees and voluntary memberships are NOT deductible. The fees must be required to maintain your professional standing.

Do I need receipts to claim union dues?

No separate receipts are needed if the amount appears in Box 44 of your T4. Your employer reports the dues paid through payroll deductions automatically. If you paid dues directly to your union (not through payroll), keep receipts as proof. CRA may request documentation during a review or audit.
