Starting a Business in Canada: Financial Checklist (2026)
Updated
Most new businesses in Canada should start as a sole proprietorship ($60–$130 to register) rather than incorporating ($200–$500+), since incorporation only makes financial sense once annual profit consistently exceeds $50,000–$75,000 — below that threshold, the added accounting costs ($1,000–$5,000/year for a corporate return) eat up most of the tax savings. Either way, separate your personal and business finances from day one: open a dedicated business bank account, get a business credit card, and set up basic bookkeeping with Wave (free) or QuickBooks ($20–$40/month).
The tax trap most new entrepreneurs fall into is not setting aside money for income tax and GST/HST as they earn. Put 25–30% of every dollar of revenue into a separate savings account for taxes — this covers both your income tax liability and the GST/HST you’ll owe once you cross the $30,000 revenue threshold and must register for GST/HST. Voluntary early registration lets you claim input tax credits on business purchases, which often makes sense if your startup costs are significant.
Start as a sole proprietorship, register your business name provincially, get a CRA Business Number, open a separate bank account, and set aside 25–30% of revenue for taxes from day one. Set up bookkeeping in week one (not at tax time), register for GST/HST either when you cross $30,000 or voluntarily if startup costs are high, and find an accountant before your first tax filing — the cost ($200–$800 for a sole proprietor) pays for itself in deductions you’d otherwise miss.
Common mistakes when starting a business in Canada
1. Not separating personal and business finances. Open a separate business chequing account from day one. Mixing funds creates tax headaches and limits your ability to deduct legitimate business expenses.
2. Missing GST/HST registration. Once you earn more than $30,000 in any 12-month period, you must register and charge GST/HST. Missing registration creates back-tax liability plus interest. Registration is free and takes minutes at canada.ca/business.
3. Ignoring quarterly tax installments. If you expect to owe more than $3,000 in federal income tax in the current and previous year, CRA requires quarterly installment payments. Missing them results in interest charges.
4. Forgetting CPP contributions. Self-employed Canadians pay both the employee and employer share of CPP — 11.9% of net self-employment income (up to the maximum pensionable earnings). This must be factored into your cash flow planning.
5. Not tracking expenses from day one. Many legitimate startup expenses (home office, vehicle, equipment, professional development) are deductible — but only if you have receipts and records.
Frequently asked questions
Do I need a business licence to start a business in Canada?
It depends on your location and business type. Most municipalities require a basic business licence ($60–$300/year). Regulated industries (trades, food service, childcare, financial services) require additional professional licences. Check with your municipal licensing office and Industry Canada before operating.
