T2125 checklist for self-employed Canadians

A practical way to organize the business records that support your self-employed income and expenses before filing time.

The T2125 is the Canadian form used to report business or professional activities. Your tax software or accountant may prepare the form, but the quality of the filing starts with the records you have kept throughout the year.

This guide is general bookkeeping education, not tax advice. For a filing decision, check current CRA guidance or speak with a qualified tax professional.

Start with the core records

Income records: invoices, payment records, sales summaries, and notes for income that did not come through an invoice.
Expense proof: receipts, supplier invoices, and a clear business purpose for each expense.
Bank and card activity: a reviewable list of business-related transactions, including items that need to be split or excluded.
Mileage and vehicle information: business kilometres and records that support business use of a vehicle.
GST/HST information: sales tax collected and input tax credit records, where registration applies.

Organize by business category before you file

Do not wait for a perfect chart of accounts. The useful first step is grouping income and expenses in a consistent way that maps to the categories your tax preparer will need. Review unclear transactions before details fade: a merchant name alone may not show whether an item was business, personal, or mixed use.

Use a monthly close habit

At the end of each month, capture missing receipts, check income, assign categories, and flag anything that needs a decision. This turns tax season into a review of organized records instead of a recovery project.
