T2125 Guide 2025: How Self-Employed Canadians Report Business Income Correctly

Introduction

For self-employed Canadians, navigating tax forms can feel overwhelming. One of the most important documents you must understand is the T2125 – Statement of Business or Professional Activities.

If you earned income in 2025 as a freelancer, consultant, contractor, Uber driver, online seller, or small business owner, this form determines how much tax you pay.

As we approach tax season, understanding the T2125 Guide 2025 will help you:

• Report income correctly

• Claim all eligible deductions

• Avoid CRA penalties

• Reduce taxable income legally

What Is the T2125 Form?

The T2125 is issued by the Canada Revenue Agency and is used to report:

• Business income

• Professional income

• Commission income

• Gig economy income

It is filed as part of your T1 personal tax return.

If you operate as a sole proprietor or independent contractor, this form calculates your net business income, which becomes part of your total taxable income.

Who Must File T2125 in 2025?

You must complete T2125 if you earned income from:

• Freelancing or consulting

• Real estate commissions

• Online selling (Amazon, Etsy, Shopify)

• Gig platforms like Uber or DoorDash

• Professional services

• Commission-based sales

Even if you did not receive a T4A slip, you must still report your income.

Key Sections of the T2125 Form

The T2125 form is divided into structured sections:

1️⃣ Business Identification

• Business name

• Industry code (NAICS)

• Business number (if registered)

• Fiscal period

2️⃣ Income Section

Report gross income before expenses, including:

• Sales revenue

• Fees

• Commissions

• Tips

• Bonuses

Accuracy here is critical.

3️⃣ Expense Section

Common deductible expenses include:

• Office supplies

• Advertising & marketing

• Professional fees (accounting/legal)

• Business insurance

• Rent

• Utilities

• Internet & phone

• Subcontractor payments

The T2125 Guide 2025 stresses proper categorization — misclassification may trigger CRA review.

4️⃣ Vehicle Expenses

If you use a vehicle for business, you must track:

• Total kilometers driven in 2025

• Business kilometers driven

Deduction = (Business KM ÷ Total KM) × Total vehicle costs

Eligible costs include:

• Fuel

• Insurance

• Repairs

• Lease payments

• Loan interest

• Depreciation (CCA – Class 10 or 10.1)

Proper mileage tracking is essential.

5️⃣ Home Office Deduction

You may claim home office expenses if:

• Your home is your principal place of business
  OR

• You regularly meet clients there

Eligible expenses:

• Mortgage interest (not principal)

• Rent

• Utilities

• Property tax

• Home insurance

• Maintenance

The claim must be prorated based on workspace percentage.

How the T2125 Affects Your Taxes

Your Net Income = Gross Income – Expenses

This net amount:

• Is added to your personal income

• Determines your income tax

• Determines CPP payable

Self-employed individuals must pay both employer and employee CPP portions.

What’s New in the T2125 Guide 2025?

Each year, the CRA updates:

• Expense limits

• CPP contribution rates

• GST/HST reporting rules

• Capital Cost Allowance adjustments

The 2025 guide includes updated thresholds and contribution calculations. Staying current prevents underreporting penalties.

Record-Keeping Requirements

The CRA requires you to:

• Keep receipts for 6 years

• Maintain mileage logs

• Retain invoices and contracts

• Track digital payments

Cloud bookkeeping or organized spreadsheets make filing easier.

Common Mistakes to Avoid

❌ Reporting net instead of gross income
❌ Forgetting digital payment income
❌ No mileage log
❌ Claiming 100% personal vehicle
❌ Incorrect CCA calculations

Professional review significantly reduces audit risk.
