Alberta Paycheck Calculator 2026

Taxable income starts from gross salary, less any registered retirement contributions and other pre-tax deductions, less the deductible part of CPP. Federal tax is then worked out on the 2026 brackets and reduced by the basic personal amount and the credits your payroll contributions earn; the same is done again with the province's or territory's own brackets and basic personal amount.

CPP splits two ways, which most simple calculators get wrong. The base portion buys a non-refundable credit at the lowest rate, while the enhanced portion and CPP2 — 4% of earnings between $74,600 and $85,000 — are deducted from taxable income instead. EI is capped at $68,900 of insurable earnings, and in Quebec QPIP is capped at $103,000.

Every employee also gets the Canada employment amount — $1,501 of non-refundable credit at the lowest federal rate, worth $210.14 off federal tax, with Yukon mirroring it at 6.4%. There is no form to file for it; it sits in the payroll formula, which is why calculators that build up from the bracket tables alone tend to miss it and overstate tax for everyone.

Quebec's equivalent is a deduction rather than a credit: the deduction for workers takes 6% of work income, capped at $1,450, off Quebec taxable income. Because it shifts the base rather than the tax, it can drop an earner just over a bracket threshold back under it — at $110,000 it is the difference between Quebec's 24% band and its 19% one.

British Columbia and Ontario both reduce tax at source for low income, and both are included here. BC's is up to $690, shrinking by 3.56% of taxable income over $25,570; Ontario's is twice a $300 basic amount less Ontario tax, which zeroes the bill under about $20,200 and is gone by roughly $26,000. Ontario's is applied before the Health Premium, so the premium is still payable by someone whose income tax it has wiped out.

The Northwest Territories and Nunavut each withhold a 2% payroll tax on employment income. It is not income tax — no credit, no deduction, no T4 box — so it is shown as its own deduction line rather than folded into territorial tax, and it does not move the territorial marginal rate. Both territories refund some of it through a cost-of-living credit at filing time, which is not modelled here.

The marginal rate shown is measured rather than looked up: the whole calculation is re-run on a slightly higher salary and the difference taken. That way Ontario's surtax, the federal basic personal amount clawback above $181,440, and every contribution ceiling are reflected in it without being special-cased.
