T2125 Tax Form: Declare Income and Expenses from a Business or Profession

Navigating the tax world doesn’t have to feel like finding your way through a maze. Enter the T2125 form: your passport to simplifying the tax process. It’s where you showcase all your hard work over the past year, declaring the income you’ve earned as well as the expenses you’ve incurred in order to thrive in your business or profession.

Because self-employed Canadians—including freelancers, gig workers, and independent contractors—report their own income, the Canada Revenue Agency (CRA) often scrutinizes their tax returns. The agency uses several methods and new AI tools to look for misreported income and large expense claims. Tax non-compliance can lead to costly fines, so it’s essential to keep detailed and accurate records for your business and to report all of your earnings. Here’s what else you need to know about filing your self-employed taxes.

What is form T2125?

The T2125 form is a Statement of Business or Professional Activities that is used to calculate your income as a self-employed person. Use the T2125 form to report your income and expenses if you are the only person in the business (sole proprietorship) or if you are in business with up to five other people (partnership).

How is income tax on your business paid in Canada?

You'll pay income tax on your business' net profit at both the federal and provincial or territorial level.

Registration for Goods and Services Tax (GST) or Harmonized Sales Tax (HST) is required within 30 days of your business revenue reaching $30,000 within a single quarter or over any four consecutive quarters. You will have to collect sales tax from your customers and remit it to the Canada Revenue Agency (CRA).

How to file self-employed taxes

To file self-employed taxes, you must first understand the definition of “self-employed.” You are self-employed if you control the time, place, and manner of performing your activities; supply your own equipment and tools, and assume the rental and maintenance costs; make a profit or incur a loss, and cover operating costs; and integrate your client's activities into your own business activities.

This applies even if your income is earned sporadically, as part of a side gig, or from multiple clients; in this case you would still have to pay self-employed or freelance taxes.

You should also understand the difference between business income and professional income.

• You have business income when you sell a product or provide a service for profit. It includes sales, commissions, or fees. You may or may not get a T-slip indicating that income.

• Professional income is the same as business income, except that you're getting paid as a member of an officially recognized profession that has a governing body (e.g., engineer, health professional, lawyer, or accountant).

If you have different businesses or professions, use separate T2125 forms for each source of income.

How do I fill out a T2125 form?

You can fill out a T2125 form more easily than you may think, by following these 3 easy steps.

Step 1: Provide identifying information

In this section, you'll enter basic information about your business, including its name, address, main product or service, and business number (if you've registered it with the CRA). You'll also need to indicate the time period during which you conducted your business activities, the accounting method you used, and, if you have a partnership, its business number and your percentage of its income and expenses. Each of your partners will have to file a T2125 form, but if there are more than five partners, they will have to file a T5013 Partnership Information Return.

Step 2: Enter income earned

In this section, you'll enter your business and professional income, gross income, and gross profit after deducting applicable costs such as wages paid and the value of your inventory.

Income can be monetary or non-monetary. If you're a content creator or travel blogger, for example, you could earn income from sources like:

• Subscriptions to your social media channels or newsletter
• Partnerships and collaborations with brands, sponsors, or other influencers
• Advertising for other businesses
• Referral codes for product promotion
• Gifts, tips, and donations
• Trips from sponsors

If you receive non-monetary income, you'll need to report its fair market value as income on your tax return.

Step 3: Enter expenses

The next step is to enter your applicable expenses, such as advertising and insurance. Certain expenses—for instance, for your home office or capital property—may require some additional calculations.

You can also claim motor vehicle expenses. Whether you have a dedicated vehicle or use your own, make sure to maintain a mileage log of business-related trips and retain all receipts of vehicle expenses. Only those related to earning business income can be deducted.

Use Area A in the T2125 form to calculate the business-use portion of your vehicle. Then, add the result to the expenses in Part 4.

What is capital cost allowance?

Capital cost allowance (CCA) refers to the depreciation of furniture, tools, vehicles, equipment, and other assets utilized in business or professional activities. Instead of deducting the full cost in the year of purchase, the cost is spread out over time based on the asset's class. The form allows you to keep track of your CCA from year to year.

Calculate your CCA by using Area A of your T2125 form. You may need to refer to your T2125 form from the previous year to fill out this part. It's important to complete it even if you are not claiming a CCA deduction, so you can demonstrate any additions or dispositions made throughout the year and maintain the undepreciated capital cost (UCC) balance.

When are self-employed taxes due?

Self-employed individuals and small-business owners have until the middle of June to file their return and avoid incurring penalties on any balance due.

• The deadline is normally June 15, and when it falls on a weekend, you have until the following Monday.

• The balance due needs to be paid by April 30 to avoid interest charges.

Some taxpayers are required to pay tax in instalments, including self-employed Canadians who owed tax of $3,000 or more (in Quebec, $1,800 or more) in the previous tax year. Instalments are due on March 15, June 15, September 15, and December 15. (Exceptions include farmers and fishers, who have one deadline on December 31.) The CRA sends reminders to those who likely have to pay in instalments.

Your self-employed taxes made simple

The T2125 form is your guide to navigating the often complicated process of filing your taxes when you work for yourself. Now that you've learned how to fill it out, you can traverse the tax world with confidence, ensuring that your filings accurately reflect your entrepreneurial journey while maximizing your deductions along the way.
