T2125 Form Explained: Statement of Business Activities
The T2125 form reports self-employment income and expenses on your Canadian personal tax return. Here's how sole proprietors complete each key section.
Form T2125, Statement of Business or Professional Activities, is the form a sole proprietor in Canada uses to report self-employment income and expenses to the CRA. You do not file it on its own: the results flow onto your personal T1 income tax and benefit return. Completing it accurately is usually the single biggest task in a sole proprietor's tax year.
Who needs to complete a T2125?
You generally file form T2125 if you operated a business or earned professional income as a sole proprietor during the year, even if the activity was part-time or produced a loss. Freelancers, independent contractors, consultants, commission salespeople, and unincorporated shop or online-store owners all fall into this group. Some partners also use the T2125 to report their share of partnership income, while the partnership itself may have separate filing obligations. Corporations are different: they file a T2 corporate return instead, so a sole proprietor who incorporates stops using the T2125 for that business income. Rental income from property is normally reported on a different form. If a client gave you a T4A slip for fees for services, you still report the amount on the T2125 — the slip does not replace it.
How the T2125 form is organized
The form is arranged so that income comes first, then expenses, and finally a calculation that produces your net income or loss. Typical sections cover identification (including your Business Number, if you have one), business income, business expenses, motor vehicle expenses, business-use-of-home expenses, and other amounts such as capital cost allowance. Because the parts run in a set order, it helps to gather your figures in that sequence rather than jumping around. The CRA publishes the current version, and section numbering can shift slightly between revisions, so always work from the copy for the tax year you are filing.
| Item | Where it is reported |
|---|---|
| Gross business or professional income | Form T2125, income section |
| Business expenses, including capital cost allowance | Form T2125, expense sections |
| Net income or loss | Carried to your T1 return |
| CPP on self-employment income | Calculated on the T1 using your net self-employment income |
| GST/HST collected and input tax credits | Your GST/HST return, not the T2125 |
Reporting income on the T2125
Income is entered at the top of the form. If you sell goods, the form separates gross sales, cost of goods sold, and the resulting gross profit; if you sell services, you generally report fees directly. You can deduct the cost of inventory you actually sold, but not inventory still on hand at year end. Your reporting period is normally your fiscal period, which for a sole proprietor is usually the calendar year. The CRA's guide explains when the cash method and the accrual method are acceptable. If you have more than one business, you generally complete a separate T2125 for each one, then combine the net results on your return. See how to report self-employment income in Canada for the reporting side of the process.
Claiming expenses and capital cost allowance
Expenses must be incurred to earn business income. Common entries include advertising, supplies, business insurance, bank fees, professional fees, and travel. Two areas have their own sections because personal use must be separated from business use: home office costs and vehicle costs, both of which need a reasonable proration. Larger purchases such as equipment are not fully deductible in the year of purchase; they are claimed over time as capital cost allowance (CCA) by class. Sole proprietorship tax deductions covers a fuller list of what is generally allowed.
CPP, EI, and your net income
Net self-employment income flows to your T1, where it also affects CPP contributions. Self-employed individuals generally pay both the employee and employer portions, and the CRA calculates the result on the return using the figures from the T2125. Rates, ceilings, and the basic exemption change over time — as of the current tax year the amounts are updated annually — so confirm the current figures on the CRA website before estimating a balance owing. If you want EI special benefits such as maternity or sickness benefits, you may be able to opt in and pay premiums. CPP for self-employed Canadians explains how the contribution is worked out.
GST/HST sits outside the T2125
GST/HST you collect is held in trust for the government. It is not business revenue and does not belong in the income lines of the T2125. Input tax credits you claim for GST/HST paid on business purchases are handled on your GST/HST return too, not as a deduction on this form. Whether you must register depends on your revenue and the small supplier rules. The mechanics are covered in how to file a GST/HST return in Canada, and it pays to keep your sales figures consistent between the two filings.
Records, filing, and fixing mistakes
Keep receipts, invoices, bank statements, and mileage logs that support every figure you enter. The CRA expects records to be kept for a set period — generally six years from the end of the last tax year to which they relate, and longer in certain situations — so confirm the current requirement on canada.ca. Your T2125 is filed as part of your T1, either through certified tax software, NETFILE, or on paper by the filing deadline. If you discover an error after filing, you can adjust the return rather than redoing everything; how to file taxes as a sole proprietor walks through the filing and correction options.
Frequently asked questions
Do I have to file a T2125 if I only earned a small amount of self-employment income?
Generally yes. The CRA expects all income to be reported, including part-time or occasional self-employment, even when no slip was issued. There is no separate minimum below which the form becomes unnecessary, because the T2125 is the reporting mechanism for business and professional income on your T1. If you are unsure whether an activity counts as a business rather than a hobby, review the CRA's guidance or speak with a tax professional.
What is the difference between a T2125 and a T4A?
A T4A is a slip a payer issues to you, reporting amounts such as fees for services. Form T2125 is your own summary of your business or professional income and expenses for the year. Receiving a T4A does not remove the need to complete a T2125 — you still report the amount, along with your related expenses, and then carry the net result to your T1 return.
Can I fill out the T2125 myself, or does an accountant have to do it?
You can complete it yourself. Certified tax software walks through the sections, and the CRA publishes both the form and its business and professional income guide. Because expenses, capital cost allowance, CPP, and GST/HST interact, many sole proprietors use an accountant, especially in the first year or when there is inventory, a home office, or a vehicle with mixed use. Either way, you remain responsible for the figures.
What happens if I made a mistake on my T2125?
You can correct it. If you filed electronically and the return was accepted, you may be able to use CRA's ReFILE service or submit a change request through CRA My Account or My Business Account, depending on your situation; paper filers can send an adjustment request. Adjusting promptly usually reduces interest, since amounts owing otherwise continue to accrue. Confirm the current process and deadlines on the CRA website.
