As a self-employed Canadian, you don't have an employer deducting taxes from your paycheque, which means you need to actively budget for your tax bill throughout the year. The key is calculating how much income tax, CPP contributions, and any HST/GST you owe, then setting that money aside before your tax deadline arrives. Most self-employed filers should aim to set aside 25 to 40 percent of their net profit depending on their province, business structure, and income level, though this varies based on your personal tax bracket and deductions.
