How Canadian Income Tax Works
| Concept | How It Works |
|---|---|
| Progressive tax | Higher income = higher rate, but only on the amount in each bracket |
| Marginal rate | The rate on your next dollar of income |
| Effective/average rate | Total tax ÷ total income (always lower than marginal) |
| Federal + provincial | You pay both — combined is your total tax |
| Tax year | January 1 to December 31 |
| Filing deadline | April 30 (June 15 for self-employed) |
