What is Form T2125 and who needs to complete it?

Form T2125 (Statement of Business or Professional Activities) is the CRA form used to report self-employment income and deductible business expenses on your personal tax return (T1). You complete T2125 if you are: a sole proprietor running a business; a freelancer or independent contractor; a professional in private practice (lawyer, accountant, doctor, engineer, etc.); a direct seller or commission agent who is self-employed (not an employee). You attach T2125 to your T1 personal tax return. If you have multiple distinct businesses, you file a separate T2125 for each. Partnerships use T2125 for the individual's share. Corporations file a separate T2 corporate tax return — T2125 is only for unincorporated self-employment. Net income from T2125 flows to Line 13500 (business income) or Line 13700 (professional income) of your T1.

What is the difference between business income and professional income on T2125?

CRA distinguishes between business income (selling goods or most services) and professional income (specific licensed professions). Business income on T2125: contractors, tradespeople, consultants, freelancers, retailers, service businesses that are not regulated professions. Professional income on T2125: lawyers, accountants, dentists, doctors, chiropractors, engineers, chiropodists, podiatrists, physiotherapists, psychologists, and other specifically listed regulated professions. The main practical difference: professionals must use the "accrual method" to report income (you report revenue when billed/earned, not when cash is received) — they cannot use cash-basis accounting. Business income earners can choose cash-basis or accrual for most industries. Check the "professional income" code on Part 1 of T2125 if you fall into a regulated profession. If unsure, use the NAICS business activity code that matches your industry.

Do I use cash-basis or accrual accounting on T2125?

CRA's general position is that income must be reported on an accrual basis (when earned, not when received). However, for most small businesses, CRA accepts cash-basis reporting in practice if it is consistently applied and does not materially distort income. Exception: professionals (lawyers, doctors, accountants, engineers) must use accrual — they report accounts receivable as income even if not yet collected. Work in progress (WIP) for professionals must generally be included in income. For most freelancers and consultants who invoice and receive payment within the same tax year, the difference between cash and accrual is minimal. Where it matters: if you sent a large invoice in December 2026 but received payment in January 2027 — under accrual, it's 2026 income; under cash, it's 2027 income. For a business with significant December receivables, accrual timing can shift substantial income between tax years.

How do I complete the CCA schedule on T2125?

The CCA (Capital Cost Allowance) schedule appears in Part 8 of T2125. For each class of depreciable property: enter the Undepreciated Capital Cost (UCC) at the start of the year; add any acquisitions during the year; subtract any disposals; apply the half-year rule for acquisitions (50% CCA on net additions); calculate CCA at the class rate; subtract CCA claimed to arrive at UCC at year-end. You carry the year-end UCC forward to next year's T2125 (it is NOT reset each year — it is a running balance). CCA is optional to claim fully — you can claim less than the maximum, and the unclaimed balance stays in your UCC for future years. If you disposed of an asset and the proceeds exceeded UCC for the class, you have recaptured CCA (taxable income). If your class goes to zero balance with proceeds less than cost, you may have a terminal loss (deductible).

What is the most common mistake people make on T2125?

The most common mistakes: (1) Mixing personal and business expenses — deducting 100% of expenses that have personal components (vehicle, phone, internet, home office) without the appropriate business-use allocation; (2) Not claiming CCA (leaving money on the table — forgetting to track assets purchased and their CCA class); (3) Not deducting health insurance premiums through a properly structured PHSP; (4) Claiming capital purchases as current expenses (e.g., deducting a $2,000 laptop as "supplies" instead of CCA Class 50 or Class 12); (5) Forgetting to carry forward unused home office expenses when they exceed business income; (6) Not calculating GST/HST paid on expenses as part of the cost (if not registered for GST/HST, the GST/HST paid IS part of your expense cost; if registered, you claim it separately as an ITC); (7) Not keeping receipts — CRA can deny any expense without supporting documentation.

Common CCA Mistakes

Mistake	Correct Approach
Forget to claim CCA	Set a recurring reminder to review CCA schedule each year
Deduct full purchase price as expense	Capital property goes to CCA schedule, not line 8570
Reset UCC to zero each year	UCC is a running balance — carry forward every year
Claim CCA beyond business-use %	Vehicle CCA must be pro-rated by business-use %
Dispose of asset without recording	Disposition reduces UCC; recapture may result if proceeds > UCC
