The income tax forms you need to report your business income depend on the form of your business.

If your business is a sole proprietorship or partnership, you report your business income on your T1 income tax form.

If you are operating a sole proprietorship, you will report your business income by completing Form T2124 (Statement of Business Activities) or Form T2032 (Statement of Professional Activities). These forms are included in the T1 income tax form package.

If you are a partner, you should first calculate the business income for all partners, then the business expenses for them, claim any expenses the partnership did not reimburse you for and any other deductible business expenses, and complete the "Details of Other Partners" chart.

However, if your partnership has had six or more partners during the fiscal year, you will also need to complete a PIR (Partnership Information Return). In this case, you will normally have a T5013 slip (Statement of Partnership Income) issued.

If your business is incorporated, you will report your business income on a T2 income tax return. But even if you run an incorporated business, you must still file your individual income tax (T1 form).
