Union & professional dues deduction calculator.
Dues shown in T4 box 44, or receipted union/professional dues, are a straight DEDUCTION against your income — not a credit, and not capped at any percentage.
Eligible dues are 100% deductible, with no dollar cap on this line. There's no fixed percentage haircut — the full amount reduces your net income, which then lowers your tax at whatever your marginal rate is.
Inputs
Deduction (line 21200)
Enter your dues and press Calculate.
What qualifies
- Annual dues for membership in a trade union or an association of public servants.
- Professional board dues required under provincial or territorial law.
- Professional or malpractice liability insurance premiums, or professional membership dues required to KEEP a professional status recognized by law.
- Parity or advisory committee (or similar body) dues required under provincial or territorial law.
What does NOT qualify
- Initiation fees.
- Licences (i.e. fees to OBTAIN a designation you don't yet hold — the rule covers dues required to KEEP an existing status).
- Special assessments.
- Charges for anything other than the organization's ordinary operating costs.
- Pension plan charges — you cannot claim these as dues even if a receipt shows them labelled that way.
It's a deduction, not a credit — and there's a GST/HST rebate too
Unlike a tax credit, a deduction reduces your NET INCOME before tax is calculated, so its value depends on your marginal rate rather than a fixed percentage. There is no dollar cap on this line: whatever amount qualifies is 100% deductible. If GST/HST was charged on your dues, you may also be able to claim an additional rebate on line 45700 — don't claim the same dues twice if both your T4 slip and a separate receipt show them.

Frequently asked questions
Is there a maximum I can deduct?
No dollar cap on this line — the full eligible amount is deductible, whether that's $50 or $5,000.
My T4 box 44 shows an amount AND I have a separate receipt — do I add them?
Only if they're for different dues. If both show the same dues, use one figure — adding them double-counts the same expense.
Can I deduct the fee to get my professional designation in the first place?
CRA's rule covers dues required to KEEP a professional status already recognized by law, and separately excludes "licences." A fee to OBTAIN a designation you don't yet hold is not the same as an annual due to maintain one you already have — if in doubt, check with CRA or a tax professional before claiming it.
Is this a federal-only deduction?
No — unlike some credits on this site, a deduction reduces net income before BOTH federal and provincial tax are calculated, so it lowers your combined bill, not just the federal portion.
Estimate only — not tax advice
This tool applies the published 100%-deductible, no-cap rule to the amount you enter. It does not verify that your specific dues qualify (see the checklist above), does not calculate the GST/HST rebate on line 45700, and any tax-saving estimate uses the marginal rate you supply rather than your actual bracket. Confirm eligibility and your exact saving with CRA or a tax professional.
