Income Tax Basics

Income Tax Basics
Core Canadian income-tax terms for reported income, tax rates, and the path to taxable income.
Net Income
Net income is the result after eligible deductions reduce total income and before later steps determine taxable income.
Total Income
Total income is the combined included income from all reported sources before deductions are applied.
Effective Tax Rate
The effective tax rate is the average rate paid across taxable income rather than the rate on the next dollar.
Marginal Tax Rate
The marginal tax rate is the rate that applies to the next dollar of taxable income, not the average rate across all income.
Taxable Income
Taxable income is the amount to which tax rates are applied after the required income-calculation steps are completed.
