Freelancer taxes in Canada (2026).

Important context

Alberta is the reason the single Canadian tax-burden number understates the spread: same country, same federal tax, but no surtax, no health premium and the highest basic personal amount in the country. The province replaced the bottom of its old flat 10% schedule with an 8% band on the first $61,200 of income from 2025, and indexed the thresholds by 2% for 2026. Credits are modelled as a zero-rate first band, exactly as in the Ontario scheme and for the same reason: $22,769 of basic personal amount plus $3,519.45 of base CPP contribution, both credited at Alberta's lowest rate of 8%. Alberta also has a supplemental non-refundable credit (factor K5P in the CRA formulas) that pays out only when a taxpayer's basic credits exceed $4,896; with the basic personal amount and CPP credit alone it is nil, so it is not modelled. The same exclusions as the Ontario scheme apply: no employment insurance, no home-office, vehicle, RRSP or private-health-plan deductions, and GST is excluded because exported services are zero-rated.

Important context

Ontario levies three things on the same profit: its own progressive tax, a surtax charged on that tax rather than on income (20% of basic Ontario tax over $5,818, plus a further 36% over $7,446), and the Ontario Health Premium, a stepped annual charge of up to $900 that is a tax and not an insurance premium — it buys nothing that a resident does not already get. The tax-engine DSL cannot charge a tax on another tax, so the surtax is folded into the Ontario bracket rates in the way every Canadian tax table presents it, with the crossover points computed from this model's own credit total. The health premium is a stepped ramp rather than clean steps — inside five narrow windows it rises linearly from one plateau to the next — and the band table here places each ramp at its midpoint, so the charge is exact on every plateau and can be up to $75 out inside a 600-wide window. All three worked examples sit on plateaus. How credits are modelled: Canada gives the basic personal amount and the base CPP contribution as non-refundable credits at the lowest rate, not as deductions, so each income tax carries a zero-rate first band equal to the credited amounts — federally $16,452 + $3,519.45, in Ontario $12,989 + $3,519.45. That reproduces the credit exactly, because the credit rate and the lowest bracket rate are the same number. It is exact for profits at or above the $74,600 YMPE, where the CPP credit is at its maximum; below that the band is wider than the real credit and the engine understates tax by up to about $490 federally. Not modelled: employment insurance, which the self-employed do not pay unless they opt in to special benefits; the Ontario tax reduction, which is nil at any income of interest here; the Canada employment amount, which self-employment income does not attract; and any deduction for a home office, vehicle, RRSP contribution or private health plan — all of which a real freelancer would claim and all of which lower these figures. GST/HST is not a levy on the freelancer and is excluded: registration is compulsory once taxable supplies pass $30,000 in four consecutive quarters, but services supplied to non-resident clients are generally zero-rated, so an exporting freelancer charges no tax and recovers the tax on their own inputs.

Important context

Québec's headline is the two-return system and the two extra contributions, but the real story is the rate on ordinary income: 19% starts at $54,345, where Ontario is still charging 9.15% and Alberta 8%. The 16.5% abatement of federal tax exists to compensate Québec for programmes it runs itself and is applied here by scaling every federal bracket rate by 0.835, which is exact because the abatement applies to net federal tax after credits. What is NOT modelled, and why: Revenu Québec's own deduction and credit for a self-employed person's QPP and QPIP contributions. The federal treatment is set out in the Income Tax Act and is modelled precisely; the Québec-side treatment is set out in Revenu Québec's guide for self-employed persons, which refuses automated requests from us, and we do not publish a tax rule we have not read at source. The effect is one-directional and roughly quantifiable: the Québec figures here are too high by the value of those credits, on the order of $500 a year at the €60,000 profile, so read 29.7% as a ceiling rather than a point estimate. The federal side carries one further small omission for the same reason as the other Canadian schemes — the credit for the employee-equivalent share of the QPIP premium, worth about $44 after abatement. Also excluded: employment insurance, which self-employed Quebecers pay only if they opt in; every discretionary deduction a real freelancer claims; and GST/QST, since services exported to non-resident clients are zero-rated.
