How Taxes Work in Canada

In Canada, you file a tax return once a year to report your income from the previous calendar year (January 1 to December 31). The Canada Revenue Agency (CRA) is the government body that collects taxes and distributes benefits and credits back to you.

Key Concepts

  • Tax Year: January 1 to December 31. Your 2025 return covers all income earned during 2025.
  • Progressive Tax: You pay higher rates only on the portion of income in each bracket, not on your entire income.
  • Federal + Provincial: You pay tax at two levels. Rates depend on your province or territory of residence on December 31.
  • Tax Deductions lower the amount of income that gets taxed (e.g., RRSP contributions).
  • Tax Credits lower the amount of tax you owe (e.g., basic personal amount).
  • Withholding: Your employer deducts tax from each paycheque. When you file your return, you settle the difference: a refund if too much was withheld, or a balance owing if too little.
