Canadian Tax Guide for Self-Employed Workers and Small Businesses (2026)

Your Complete Canadian Tax Resource

If you are self-employed, freelancing, or running a small business in Canada, your tax obligations are more complex than a salaried employee's. You handle your own income tax, CPP contributions, GST/HST, quarterly instalments, and CRA reporting — with no employer doing it for you.

This hub page connects every tax guide we have written into one organized resource. Start with whichever topic is most relevant to your situation, or work through them in order for a complete understanding of Canadian self-employment taxes.
