I’m Self-Employed and Received a T4A. How Do I Report This Income?
If you’re self-employed, a business client may provide a T4A form that reports the income they paid you in the previous year. You will need to include the income on your T2125. If you are using tax preparation software, enter the information in the T4A section, and indicate that you would like to include the income on your T2125. When you report the rest of your revenue, make sure to deduct the revenue that was included on your T4A so you don’t double report your income.
It’s important not to rely on your clients to keep a record of what they’ve paid you. Some clients will not send you a T4A, mainly if they are a consumer and not a business. It’s your responsibility to keep accurate records of things like gross and net income for your business in the previous year and enter it on Form T2125.
