Tax deductions by occupation in Canada

What the work costs is much the same wherever you do it. How you claim it is not — so each guide below pairs the spending with the rules that apply in Canada. You report through Form T2125 with your personal return.

Income tax in Canada

Self-employment income goes on Form T2125 and is added to your other income, taxed at combined federal and provincial rates. You also pay both the employee and employer halves of CPP contributions on your net self-employment earnings.

This is general information, not personal tax advice — what you can claim depends on your circumstances, so check with the CRA or a registered tax adviser, and keep records to back up every claim.

How Canada treats the big three

Vehicle and travel

Vehicle costs are claimed on the business-use share, worked out from a logbook of business versus total kilometres.

Home workspace

Business-use-of-home expenses are claimed on the share of your home used for work, and generally cannot create or increase a business loss — the unused part carries forward.

Equipment and higher-cost gear

Equipment is claimed through Capital Cost Allowance, at the rate for the class the asset falls into, rather than deducted in full up front.

Worth knowing in Canada

You are generally a "small supplier" until taxable supplies exceed the registration threshold either in a single calendar quarter or across four consecutive quarters — the single-quarter trigger is the one people miss after one big month. Cross either and GST/HST registration is required, and the rate you charge depends on your customer’s province, not yours.

Self-employed tax in Canada — common questions

When do I have to register for GST/HST?

Once you stop qualifying as a small supplier — broadly when taxable supplies exceed the registration threshold in a single calendar quarter, or across four consecutive quarters. Registering before you have to is optional, and lets you claim input tax credits on business purchases. This is general information, not personal tax advice — what you can claim depends on your circumstances, so check with the CRA or a registered tax adviser, and keep records to back up every claim.

Do I pay CPP on self-employment income?

Yes. Where an employee and employer each pay a share, a self-employed person pays both halves on their net self-employment earnings, calculated with the return. This is general information, not personal tax advice — what you can claim depends on your circumstances, so check with the CRA or a registered tax adviser, and keep records to back up every claim.
