Question 1

Which tax years and provinces does this calculator support?

Accepted Answer

This calculator covers the 2025 and 2026 tax years. It supports federal income tax plus all 12 provinces and territories except Quebec: Ontario, British Columbia, Alberta, Saskatchewan, Manitoba, Nova Scotia, New Brunswick, Prince Edward Island, Newfoundland & Labrador, Northwest Territories, Yukon, and Nunavut. Quebec is excluded because it uses distinct payroll rules — QPP instead of CPP, QPIP premiums, and a provincial abatement — that require dedicated treatment. Use the year toggle in the calculator header to switch between 2025 and 2026.

Question 2

Does an RRSP contribution reduce tax in Canada?

Accepted Answer

Yes. RRSP contributions generally reduce your taxable income for income tax purposes, which lowers both federal and provincial income tax. This calculator shows that by reducing taxable income first, then separately showing the RRSP as a real deduction from take-home pay.

Question 3

Does this calculator include CPP and EI?

Accepted Answer

Yes. It includes employee Canada Pension Plan contributions — both the base rate and the second additional CPP2 contribution — plus Employment Insurance premiums using the 2025 employee rates and earnings ceilings. Those payroll deductions are shown separately from income tax so you can see how much each one affects your net pay.

Question 4

Does this calculator include the Ontario Health Premium and provincial surtaxes?

Accepted Answer

Yes. If you select Ontario, the calculator adds the Ontario Health Premium based on taxable income, plus the Ontario surtax (20% on basic Ontario tax above $5,315 and an additional 36% above $6,802). Prince Edward Island residents also pay a 10% surtax on basic PEI tax above $12,500, which is included. These charges are displayed separately inside the provincial tax breakdown.

Question 5

Why does province selection change take-home pay?

Accepted Answer

Canada uses a federal tax layer plus a provincial or territorial tax layer. Each province has its own tax brackets, rates, and basic personal credit amounts. Some provinces also charge surtaxes on top of basic provincial income tax. The same gross salary can produce meaningfully different take-home results depending on where you live.

Question 6

Is this a full Canadian payroll calculator?

Accepted Answer

It is a comprehensive employee-focused income tax calculator for all provinces and territories except Quebec. It models RRSP deductions, CPP (base and CPP2), EI, federal and provincial basic personal credits, the Ontario and PEI surtaxes, and the Ontario Health Premium. It does not model Quebec payroll, self-employed CPP treatment, or every possible non-refundable credit.
