This hub has 18 income tax calculators for the 2026 tax year. They work out federal and provincial tax together, then split off the cases that behave differently: capital gains, dividends, rent, self-employment and the deductions and credits that shrink a bill. Quebec residents file a separate provincial return, so their numbers fit together a little differently.
Which income tax calculator should I use first?
Start with the income tax calculator. It combines the federal and provincial layers for any province and shows your tax, your average rate and what’s left.

- Tax Instalments Calculator

What rate do I pay on the next dollar I earn?
That is your marginal rate, and it usually sits above your average rate. The marginal tax rate calculator shows it before you take a raise, a side job or an RRSP deduction. Come tax time, the tax refund calculator sets the tax already withheld against the tax you owe, so you know whether a cheque or a bill is on the way.
Is all income taxed the same way?
No. Half of every capital gain enters your income, and the capital gains tax calculator applies that to shares and property. Dividends get a gross-up and a credit, which the dividend tax calculator works through for eligible and ordinary ones. The rental income tax calculator adds rental profit on top of your other income.
If you work for yourself, nobody withholds tax and you carry both the employee and employer parts of CPP. The self-employed tax calculator covers a full business. For a weekend gig on top of a salary, the side hustle tax calculator shows the extra income tax and CPP. The tax instalments calculator plans the quarterly payments the CRA may ask for.
Which deductions and credits can I estimate?
The deductions and credits calculator shows what an RRSP deduction, tuition or medical costs save in your province. Six single-purpose calculators go further:
- The child care expense deduction calculator applies the per-child limits and the earned income cap.
- The donation tax credit calculator compares giving everything in one year with spreading gifts over several.
- The home office deduction calculator checks which rent and utilities an employee can claim.
- The medical expense credit calculator lets you compare different 12-month periods.
- The moving expenses deduction calculator tests the distance rule and the income limit on what you can deduct.
- The pension income splitting calculator looks for the split that cuts a couple’s combined tax.
What if I sold a cottage or a rental property?
The principal residence exemption calculator estimates the tax when you sell a cottage, a second property or a home you did not live in every year. If you rented the place out and claimed capital cost allowance, the rental property CCA recapture calculator shows how those claims come back as income at sale.
All results are estimates for the 2026 tax year. They follow the published federal and provincial rules, but a filed return can differ because of credits and deductions only you know about.
Frequently asked questions
What's the difference between marginal and average tax rate?
Your average rate is your total tax divided by your income. Your marginal rate is the rate charged on the next dollar you earn, and it is the one that matters when you weigh a raise, a side job or an RRSP deduction.
Are federal and provincial tax worked out together?
They are worked out separately, then added. Each has its own brackets, and in some provinces the provincial part also carries surtaxes or reductions. The income tax calculator combines both for you.
Does the tax year follow the calendar?
Yes. A 2026 personal return covers January 1 to December 31 and is due in the spring of 2027. Income earned in those months belongs to that tax year, whatever the pay date.
Can I file my return with these tools?
No. They give planning estimates and nothing more. To file, use certified tax software or a professional, and treat the CRA's own pages as the official reference.
Is a capital gain taxed like a salary?
Not in full. Half of a capital gain is added to your income and taxed at your marginal rate, while a salary is fully taxable. The capital gains calculator shows the extra tax on a sale in your province.
Do self-employed people pay tax in instalments?
Often, yes. No employer withholds tax from business income, so the CRA may ask for quarterly payments once your tax owing is high enough. The instalments calculator checks that and splits the year into four payments.
