Tax Calculators for Canada: 7 Free Financial Tools (2026)
Seven free tools built on 2026 rates, from a CPA who has served Mississauga since 1995. No sign-up, no email required.
Which calculator do I need?
If you're planning your personal taxes, start with the Income Tax Calculator for your take-home pay and marginal rate, then use the RRSP Tax Savings Calculator to see how much a contribution could save you.
If you run a business, the GST/HST Calculator adds the right sales tax to an invoice, and the Reverse GST/HST Calculator breaks down a tax-included receipt for your books. If you own a corporation, the Salary vs. Dividends Calculator compares the two ways to pay yourself.
When the estimate turns into a return, our tax preparation and GST/HST filing services take it from there.
Tax Calculator Questions
Are these calculators up to date for 2026?
Yes. The tax calculators use 2026 federal and provincial brackets, 2026 CPP and EI figures and current sales tax rates for every province and territory, including Nova Scotia's HST, which dropped to 14% on April 1, 2025. Quebec residents file a separate provincial return with Revenu Québec, and the Income Tax Calculator applies the Quebec federal abatement.
Can I estimate my refund or balance owing before I file?
Yes. Run the Income Tax Calculator with your income for the year; it also shows your marginal and average tax rates. Then compare the result with the income tax already deducted from your pay, shown in box 22 of your T4 slips. If more was deducted than you owe, the difference is roughly your refund; if less, it's roughly what you'll owe.
Credits the calculator doesn't capture, such as tuition, medical expenses or donations, will change the final number. If you're thinking about an RRSP contribution, the RRSP Tax Savings Calculator shows how much it could add to your refund.
Do these calculators work out payroll deductions?
For your own pay, yes: the Income Tax and Salary to Hourly calculators show the income tax, CPP and EI deducted from a salary. If you're an employer running payroll, the CRA's Payroll Deductions Online Calculator uses each employee's TD1 claims and pay period; for Quebec provincial tax, Revenu Québec has its own tools. You can also have our payroll service handle the remittances.
Are there calculators for business taxes?
Three of the seven are built for businesses: the GST/HST and Reverse GST/HST calculators for invoices and receipts, and the Salary vs. Dividends Calculator for incorporated business owners. Corporate income tax on a T2 return depends on too many factors, such as the small business deduction, passive investment income and associated corporations, for a quick online estimate. For that, our bookkeeping and tax preparation services can help.
