How does self-employment affect your income tax return?
As self-employed persons run their own business, their business income should be declared on their personal returns. Self-employed income is categorized and filed the same way business income is, if their business is a sole-proprietorship or partnership.
Therefore, self-employed status doesn't negatively impact your tax return. Instead, self-employed individuals will fill out and file the T2125 form and the T1 return, like other individuals filing business income returns. They will then pay the same tax amount as any employed wage earner that falls within the same tax bracket.
You can also write-off expenses just like businesses. There are various deductions that can be made for self-employment expenses, such as home office costs, office supplies, vehicle expenses, business travel, and more.
