Canadian Tax Basics for First-Timers
Canada's tax year follows the calendar year, and most people file a return by the end of April. Even if you earned little, filing is worth it: it unlocks benefits and credits paid out through the year.
Why everyone should file
Filing is how you receive payments like the GST/HST credit and, for parents, the Canada Child Benefit. Skipping a return can mean leaving real money unclaimed, even on a low income.
The documents you need
Employers issue a T4 slip summarising your income and deductions. Banks and other institutions issue their own slips for interest or investments. Keep them together as they arrive in late winter.
Federal and provincial tax
You pay both a federal and a provincial portion, but you file a single combined return. Rates are progressive, meaning higher income is taxed at higher marginal rates — only the income within each band is taxed at that band's rate.
Registered accounts worth knowing
The TFSA lets investments grow tax-free, while the RRSP defers tax on contributions until retirement. Both are powerful, and contribution room builds over time, so it pays to learn them early.
Free tax-clinic programs help eligible residents file at no cost, and certified software walks you through the rest. Start with one return and it quickly becomes routine.
