Self-employed Canadians must keep detailed financial records for a minimum of six years from the end of the tax year they relate to, according to CRA rules. This includes invoices, receipts, bank statements, payroll records (if you have employees), and supporting documents for all business income and expenses claimed on your tax return. The CRA can request these records during an audit, and failing to produce them may result in reassessment, penalties, or denied deductions. Starting 2026, maintaining organized records isn't just a legal requirement—it's your best defense against costly mistakes and audit stress. When you're self-employed, the CRA expects you to prove every dollar of income and every deduction you claim. Unlike employees who have T4 slips issued by their employer, self-employed workers rely entirely on their own documentation. The CRA uses these records to verify: Whether your reported business income matches actual deposits That claimed expenses are legitimate and reasonable Your eligibility for specific credits or deductions Whether you've properly calculated CPP contributions and tax installments Weak record-keeping can trigger audits and assessments that force you to repay taxes with interest and penalties. Strong documentation protects you and makes tax filing faster and less stressful.
