Country-specific guidance
In Canada, a self-employed person can generally claim reasonable expenses incurred to earn business income, while personal costs are excluded and mixed-use costs must be apportioned. Employees usually need specific conditions and employer forms before claiming employment expenses. Retain invoices, receipts and a clear business-use calculation.
Worked example: Worked example (illustrative): if a welder spends C$1,900 on eligible work costs and can substantiate 100% business use, the potential deduction is C$1,900. The tax saved depends on taxable income, filing status, region and the applicable rules; this page is an estimate, not a filing result.
