What is the T2125 form in Canada?

Form T2125 is the CRA's Statement of Business or Professional Activities. Every self-employed person, freelancer, or sole proprietor in Canada must file it with their T1 tax return to report business income and expenses.

Do I need to fill out a T2125 if I only freelanced part-time?

Yes. Any self-employment income — even from a side hustle — must be reported on a T2125. There is no minimum income threshold. If you earned $500 or $50,000 freelancing, you need a T2125.

Can I fill out the T2125 myself or do I need an accountant?

Most freelancers with straightforward businesses can fill out the T2125 themselves using tax software like TurboTax or Wealthsimple Tax. These programs walk you through each section. You can also use FreelancerTax's free T2125 Generator to pre-fill the form from your bank CSV.

What is the NAICS code on the T2125 and how do I find mine?

The NAICS (North American Industry Classification System) code identifies your type of business. Common codes for freelancers: 541110 (law), 541211 (accounting), 541310 (architecture), 541410 (graphic design), 541511 (programming), 541611 (management consulting), 541810 (advertising), 541920 (photography), 711511 (writers/authors). Find yours at Statistics Canada's website or search 'CRA NAICS code' plus your industry.

What happens if I make a mistake on my T2125?

You can file a T1 Adjustment Request (T1-ADJ) to correct errors after filing. If you accidentally overclaimed deductions, it's better to self-correct before the CRA catches it. If you underclaimed, you have up to 10 years to amend and claim missed deductions.

How to Fill Out the T2125 Form: Step-by-Step Guide for Canadian Freelancers (2026)

If you're a freelancer, consultant, or sole proprietor in Canada, the T2125 (Statement of Business or Professional Activities) is the most important form on your tax return. It's where you report your business income, claim deductions, and calculate your net self-employment income.

The problem? The T2125 has 8 parts spread across 4 pages, with dozens of line numbers that look like they were designed to confuse you. This guide walks through every section with plain-English explanations and real-world examples.

What Is the T2125 Form?

Form T2125 is filed as part of your annual T1 income tax return. It calculates your net business income — the number that flows into your T1 and determines how much tax (and CPP) you owe.

You need a T2125 if you:

Earned any self-employment or freelance income
Run an unincorporated business (sole proprietorship or partnership)
Have professional income (consultants, accountants, lawyers, doctors)

💡 Good news: You probably won't fill it out on paper If you use TurboTax, Wealthsimple Tax, or any certified tax software, the T2125 questions are woven into the interview process. But understanding what each section means helps you claim everything you're entitled to.

Part 1: Identification

This section captures your basic business details:

Field	What to Enter	Example
Business name	Your business name or your personal name if no registered business	"Sarah Chen Web Design" or "Sarah Chen"
Business address	Your main business location (home address if home-based)	45 Queen St W, Toronto, ON M5H 2M5
Industry code (NAICS)	6-digit code for your type of business	541511 (custom computer programming)
Business number	Your 9-digit CRA business number + program ID (if you have one)	123456789 RT0001
Fiscal year	Usually Jan 1 – Dec 31 for individuals	2025-01-01 to 2025-12-31
Type of business	Sole proprietorship, partnership, or professional	Sole proprietorship

Finding Your NAICS Code

Common NAICS codes for freelancers:

Code	Industry
541110	Law offices
541211	Accounting
541310	Architecture
541410	Graphic design
541511	Computer programming
541611	Management consulting
541810	Advertising agencies
541920	Photography
541990	Other professional services
711511	Writers and authors
711410	Performing arts (musicians, etc.)
512110	Video production

⚠️ Multiple businesses? If you have two distinct businesses (e.g. web design AND photography), file a separate T2125 for each one. If it's all one business offering multiple services, use one T2125 with the code that best represents your main activity.

Part 2: Internet Business Activities

This is a new-ish section the CRA added. It asks:

Do you have a business website? (Yes/No + URL)
What percentage of your revenue comes from the internet?
Do you use a third-party platform to sell? (Etsy, Upwork, etc.)

Be honest here — the CRA uses this to cross-reference with platform reporting. Many platforms now report seller data directly to the CRA.

Part 3A: Business Income

This is where you report your gross revenue. Key lines:

Line	Description	What Goes Here
8299	Gross sales, commissions, or fees	Total invoiced amount for the year (before expenses)
8230	Other income	Interest, grants, subsidies, etc.
8299	Gross business income	Sum of all revenue lines

🚫 Common mistake: Reporting net deposits instead of gross Report the full amount you invoiced, not what landed in your bank account after platform fees. If you billed $50,000 through Upwork and they took $5,000 in fees, report $50,000 as gross income and $5,000 as a business expense (Line 8860 — Professional fees).

Part 3B: Cost of Goods Sold

Most freelancers can skip this section. It's for businesses that sell physical products and need to track inventory, raw materials, and manufacturing costs.

If you're a photographer who buys prints to resell, or a designer who ships physical products, you'd use this section. For service-based freelancers — skip it.

Part 4: Net Income (Loss) Calculation

This is the big one. Part 4 is where your gross income minus your expenses = net business income.

Expense Line Items

Here are the T2125 expense lines most relevant to freelancers:

Line	Category	What to Include
8521	Advertising	Google Ads, Facebook Ads, business cards, website costs, Canva Pro
8523	Meals & entertainment	Client meals, business meals (50% deductible only!)
8590	Bad debts	Invoices you couldn't collect (must have made reasonable effort)
8690	Insurance	Business insurance, E&O insurance, liability insurance
8710	Interest & bank charges	Business credit card interest, bank fees, payment processing fees (Stripe, PayPal)
8760	Business taxes, fees, licences	Professional memberships, business licences, domain registrations, software subscriptions
8810	Office expenses	Stationery, ink, small office supplies (items under ~$500)
8811	Supplies	Materials used in your business (not resold)
8860	Professional fees	Accountant, lawyer, bookkeeper fees, platform fees (Upwork, Fiverr commissions)
8871	Management & admin fees	Virtual assistant, subcontractor admin costs
8910	Rent	Office/studio/co-working space rent
9060	Salaries, wages, benefits	Subcontractor payments (with T4A slips if over $500)
9180	Property taxes	Business property taxes (NOT home — that's Part 7)
9200	Travel	Flights, hotels, conference travel (NOT daily commuting)
9220	Telephone & internet	Business % of phone bill + internet (e.g. 50% of $100/mo = $600/yr)
9270	Other expenses	Anything that doesn't fit elsewhere (describe it)

The 50% Meals Rule

Line 8523 (Meals & entertainment) is capped at 50% deductible. If you spent $2,000 on client lunches, you can only claim $1,000. This is one of the most commonly misunderstood rules on the T2125.

Part 5: Motor Vehicle Expenses

If you use your personal vehicle for business (meeting clients, deliveries, etc.), you can claim a portion of your vehicle costs.

You need to track:

Total kilometres driven in the year
Business kilometres driven in the year
Your actual expenses: gas, insurance, maintenance, lease payments, parking, etc.

Your deductible portion = (business km ÷ total km) × total vehicle expenses.

⚠️ Keep a mileage log! The CRA frequently asks for a mileage log during audits. Use a simple app or spreadsheet — date, destination, purpose, and kilometres. Without a log, the CRA can disallow your entire vehicle claim.

For more details, see our complete guide to vehicle expense deductions.

Part 6: Calculating Net Income

This section does the math:

Line 9369: Total of all your Part 4 expenses
Line 9369: Subtract from gross income (Line 8299)
Line 9945: Add business-use-of-home expenses (Part 7)
Line 9946: Your net business income (or loss)

This final number (Line 9946) flows to your T1 income tax return. It's the number used to calculate your income tax and CPP contributions.

Part 7: Business-Use-of-Home Expenses

If you work from home, this section lets you claim a portion of your housing costs as a business deduction.

Eligible Expenses

Rent (if you rent)
Mortgage interest (NOT the principal payment)
Property tax
Utilities (heat, hydro, water)
Home insurance
Maintenance and minor repairs

Calculating Your Business-Use Percentage

The CRA accepts two methods:

Square footage method: Office sq ft ÷ Total home sq ft. Example: 150 sq ft office ÷ 1,200 sq ft home = 12.5%
Room count method: Rooms used for business ÷ Total rooms. Example: 1 room ÷ 8 rooms = 12.5%

Then multiply your total housing costs by that percentage.

💡 Simplified method available For 2020+ tax years, you can claim $2/day for each day you worked from home, up to $500/year. No receipts needed. This is simpler but usually gives a smaller deduction than the detailed method. See our full home office guide.

🚫 Important limitation Home office expenses can NOT create or increase a business loss. If your business income is $5,000 and your other expenses are $5,000 (net income = $0), you can't claim home office to create a loss. You can carry the unused portion forward to next year.

Part 8: Other Information

The final part asks a few yes/no questions:

Did you have any partners in this business?
Did you dispose of any business property?
Did you claim capital cost allowance (CCA)?

Most solo freelancers answer "No" to all of these unless they made a major equipment purchase (laptop, camera, etc.) that they want to depreciate over multiple years using CCA.

Capital Cost Allowance (CCA) — A Quick Note

If you bought equipment costing more than ~$500 (laptop, camera, desk, etc.), you generally can't deduct the full cost in one year. Instead, you use Capital Cost Allowance (CCA) — the CRA's version of depreciation.

Common CCA classes for freelancers:

Class	Rate	Assets
8	20%	Furniture, equipment, printers
10	30%	Vehicles, general equipment
10.1	30%	Passenger vehicles over $37,000
50	55%	Computer hardware, phones, tablets
12	100%	Software (less than $500), small tools

The Accelerated Investment Incentive allows you to claim a larger deduction in the first year. For most freelancers with a $2,000 laptop purchase, the CCA calculation is straightforward — but if you're unsure, our Expense Tracker template handles it automatically.

Putting It All Together: A Real Example

Let's say Sarah is a freelance web developer in Toronto. Here's her T2125:

Line	Description	Amount
8299	Gross revenue (client invoices)	$85,000
Expenses
8521	Advertising (Google Ads, domain, hosting)	$1,200
8523	Meals & entertainment (50% of $1,600)	$800
8710	Interest & bank charges (Stripe fees, bank fees)	$2,550
8760	Software subscriptions (Adobe, GitHub, Figma)	$2,400
8810	Office expenses	$350
8860	Professional fees (accountant)	$800
9200	Travel (1 conference)	$1,500
9220	Telephone & internet (60% business use)	$1,080
CCA	Computer equipment (Class 50)	$825
9369	Total expenses	$11,505
9945	Home office (12.5% × $18,000 housing costs)	$2,250
9946	Net business income	$71,245

Sarah's net income of $71,245 flows to her T1, where she'll pay approximately $14,800 in federal + provincial income tax, plus ~$8,070 in CPP. Her effective tax rate on business income is about 32%.

Common T2125 Mistakes to Avoid

1. Forgetting to Claim the Home Office

If you work from home even part-time, you're leaving money on the table. At minimum, claim the $2/day simplified method ($500/year). The detailed method often gives $2,000-4,000+ in deductions.

2. Not Separating Personal and Business Expenses

That Amazon order with printer ink AND a birthday gift? Split it. Only claim the business portion. The CRA expects you to separate mixed purchases.

3. Claiming 100% of Phone and Internet

Unless you have a dedicated business phone line, the CRA expects you to claim a reasonable business-use percentage — usually 50-70%. Claiming 100% is a red flag.

4. Missing Platform Fees

Upwork's 10% commission, Stripe's 2.9% + $0.30 per transaction, PayPal fees — these are all deductible business expenses (Line 8860 or 8710). They add up to thousands of dollars per year.

5. Not Reporting All Income

With the CRA receiving data from platforms, banks, and foreign tax agencies, unreported income is increasingly detectable. Report everything — even cash payments and barter transactions.

For more audit risks, see our guide to 10 CRA audit red flags for freelancers.

What Happens After You File Your T2125?

Your T2125 net income flows into your T1 personal tax return, where it:

Gets added to your other income (employment, investment, etc.)
Determines your income tax bracket
Triggers CPP contributions (both employee and employer portions — about 11.9% of net income)
May affect your RRSP contribution room (net income increases your limit)
May trigger quarterly instalment requirements for next year

Frequently Asked Questions

Can I file a T2125 without a business number?

Yes. You don't need a business number to report self-employment income. You only need a business number if you register for HST/GST or have payroll obligations.

What if I had a business loss?

Business losses can be applied against your other income (employment, investment) to reduce your overall tax. This is called a non-capital loss. You can carry it back 3 years or forward 20 years. However, the CRA may question repeated losses as a sign your "business" is really a hobby.

Do I need to keep receipts?

Yes — keep all receipts and records for 6 years from the end of the tax year. Bank/credit card statements, invoices, contracts, mileage logs. If the CRA audits you and you can't produce records, they can disallow your deductions entirely.

When is the T2125 due?

Self-employed Canadians have until June 15 to file their T1 (which includes the T2125). However, any tax owing is due April 30. File early to avoid penalties on unpaid tax. See our complete deadlines guide.
