Self-employed taxes: from records to filing
Start with your business structure and tax year. Organize income and expense records, check the return that applies, and keep income-tax, GST/HST and payroll tasks separate. Use the linked CRA instructions to confirm what you need before filing.
Confirm your business structure
A sole proprietor reports business income through their personal income tax return. An incorporated business follows the corporate route. If you are a partner, check partnership reporting as well.
Organize income and supporting records
Gather invoices, receipts, statements and your bookkeeping records. Reconcile what you earned before calculating expenses; avoid building a return from bank deposits alone. CRA explains which records support business income.
Choose the correct reporting form
T2125 covers business or professional activities. Farming and fishing have different forms. Follow the instructions for your activity, including how to report expenses, rather than assuming one form covers every business.
Separate filing from payment
Write down the tax year, filing deadline, payment deadline and any instalment requirements from the current CRA guidance. Submitting a return does not itself pay a balance.
Check other accounts separately
If GST/HST, payroll or provincial accounts apply, give each its own filing and payment row. Keep submission and payment confirmations privately.
Common questions
What should I ask first?
Try “I’m a sole proprietor in Alberta. How do I file my business taxes?” Then specify the tax year for deadline questions.
Can this checklist calculate my tax?
No. It organizes the work and links you to official instructions. Use suitable tax software or a qualified professional for calculations and advice on your circumstances.

Business taxes and payments in Canada
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.
