Almost every adult in Canada files a tax return once a year — but the system is rarely explained in plain language. Which rate applies to your income? What is the difference between a deduction and a credit? When is your return due, and what happens if you miss the deadline? This site answers those questions in plain English, with 2026 figures from the Canada Revenue Agency and links to check them yourself.

Start here, in five minutes

If you have never filed before, start with how Canada’s tax system works and then filing your first return. If money is the question, go straight to 2026 federal brackets or deductions and credits. If a deadline is near, read deadlines and penalties. If the CRA has written to you, read reviews, audits and appeals.

All eleven guides

How the system works

How Canada’s tax system works — the CRA, federal and provincial tax, the T1 return, and who must file. 2026 federal brackets — the five brackets from 14% to 33%, the basic personal amount, and a worked example. Filing your first return — gathering slips, NETFILE software, CRA My Account, and what happens after you file.

Deadlines, money and slips

Deadlines & penalties — 30 April, 15 June for the self-employed, the late-filing penalty, interest, and instalments. Deductions & credits — what most people claim, including RRSP and TFSA pointers. Tax slips — T4, T4A, T5, T3 and T2202, which boxes matter, and missing slips. Refunds & amounts owing — Notices of Assessment, how refunds are paid, and payment arrangements.

Work, provinces and benefits

Self-employed taxes — the T2125, expenses, paying both shares of CPP, and instalments. Provincial tax — how your province adds tax, Ontario as an example, and Quebec’s separate return. Benefits overview — GST/HST credit, Canada Child Benefit, CWB and DTC, with links to the full guides.

Your rights

Reviews, audits & appeals — reassessment, the notice of objection, the Appeals Division, and the Tax Court.

What this site will not do

This site will not tell you what to claim, what you owe, or how to file your own return — only the CRA and a qualified tax professional can do that for your situation. It will not recommend any tax software, preparer, or filing position. It is not affiliated with the Canada Revenue Agency, the Government of Canada, or Revenu Québec. What it will do is explain how the system works, what things cost, what the deadlines are, and what your rights are, clearly enough that you can deal with the CRA with confidence — and know where to check the current position on canada.ca.
