Canada Self-Employed Tax Calculator 2026

CPP is not one charge, and that is why it splits

The headline is simple enough: an employee pays 5.95% and their employer pays 5.95%, so a self-employed person pays 11.9% of contributory earnings — everything between the CA$3,500 basic exemption and the CA$74,600 ceiling, for a maximum of CA$8,460.90. Above that ceiling, CPP2 charges 8% on the next CA$10,400, a further CA$832.

What is less obvious is that the CRA decomposes the rate into a base component of 4.95% per side, a first additional component of 1%, and CPP2. Only the base employee share — up to CA$3,519.45 — is claimed as a non-refundable credit. The rest of what a self-employed person pays is a deduction from income.

That distinction is worth money in a direction most summaries miss. A credit is valued at the lowest rate of the scale — 14% federally. A deduction comes off at your marginal rate. So the larger, deducted portion of your CPP is worth more the more you earn, and it also reduces the net income figure that the federal basic personal amount is tested against.

The province changes more than the headline suggests

Combined top marginal rates run from 54.80% in Newfoundland and Labrador down to 44.50% in Nunavut. As with Spain's regional scales, those figures describe the top of each scale and not what a working freelancer pays, because the income at which each province reaches its top rate varies enormously — Nova Scotia gets there at CA$157,124 and Newfoundland and Labrador not until CA$1,141,275.

Change the province in the calculator while holding revenue steady to see the real spread at your own income. Basic personal amounts pull in the same direction and are not small: Alberta allows CA$22,769 against Nova Scotia's CA$11,932, a gap of CA$10,837 of income shielded at the province's lowest rate.

The federal personal amount shrinks as you earn

The federal basic personal amount is CA$16,452 while net income stays at or below CA$181,440. Between there and CA$258,482 it falls on a straight line to CA$14,829, and stays at that floor above. The withdrawal is gentle — CA$1,623 spread over CA$77,042 of income, which adds about 0.3 of a percentage point to the marginal rate through that band — but it is one more reason the posted bracket rate is not the rate you face.

Manitoba does something considerably sharper with its own amount, withdrawing all CA$15,780 of it between CA$200,000 and CA$400,000.

What this does not model

A resident sole proprietor outside Quebec, with business income only and no other credits or deductions. Employment Insurance is optional for the self-employed and is excluded. Ontario and Prince Edward Island levy surtaxes on provincial tax that these tables do not carry, so both are slightly understated at higher incomes. RRSP contributions, the Canada workers benefit, spousal and dependant credits, and instalment requirements are all outside scope.

GST/HST is separate again. You stop being a small supplier at CA$30,000 of revenue — and if you cross it inside a single calendar quarter, you must charge tax on the very supply that took you over. Every country's threshold sits together in our VAT and GST registration thresholds guide.

One note on sourcing, because it affected this page. The CRA's 2026 claim code table implies a lowest British Columbia rate of 5.06%, the 2025 figure, while the CRA's own rates page and the Province of British Columbia both publish 5.60% for 2026. We use 5.60%. The disagreement surfaced because every province's basic personal amount times its lowest rate should reproduce the CRA's published credit value, and eleven of twelve did.
