Business taxes and payments in Canada
How do I do my business taxes and payments?
Business taxes can involve separate income-tax, sales-tax and payroll tasks. The right returns and payment accounts depend on your business structure, registrations and activities. Start by separating these obligations rather than treating them as one business-tax bill.
Where to begin
- Identify your business structure and use the matching income-tax route: corporation, sole proprietor or partnership.
- Check which GST/HST registration, collection, filing and payment tasks apply to your business.
- If you pay employees, review payroll deductions, remittances and information returns.
- Use CRA payment guidance for the relevant tax account and period; check payment deadlines separately from return filing.
- Check whether instalments apply and confirm that CRA received and applied your payment.
