Question 1

How do I report side hustle income in Canada?

Accepted Answer

Report side hustle income on your T1 personal tax return using Form T2125 (Statement of Business or Professional Activities). You report gross income, deduct eligible expenses, and the net amount is added to your other income. If you also have T4 employment income, both are combined for your total taxable income.

Question 2

When is a side hustle a business vs. a hobby?

Accepted Answer

CRA considers an activity a business if it is undertaken with a reasonable expectation of profit and is carried on in a businesslike manner. Factors include: do you keep records, do you promote the activity, do you have a business plan, and is the activity ongoing? If CRA considers it a hobby, you cannot deduct losses against other income.

Question 3

How does T2125 work alongside a T4?

Accepted Answer

You report your T4 employment income as usual and attach Form T2125 for your self-employment income. Both are combined on your T1 return. Your employment income is subject to CPP through payroll deductions, while your self-employment income triggers additional CPP at the self-employed rate on the side hustle portion.

Question 4

Do I pay CPP on my side hustle income?

Accepted Answer

Yes, if your net self-employment income exceeds $3,500. You pay both the employee and employer CPP portions (11.9% combined) on your side hustle earnings. However, if your employment income already covers the maximum CPP contribution ($71,300), you may only owe CPP2 (4%) on earnings between $71,300 and $81,200.

Question 5

When am I required to pay tax by instalments?

Accepted Answer

If your net tax owing (after employer withholdings on T4 income) exceeds $3,000 in the current year and either of the two preceding years, you must pay quarterly instalments. Side hustles often trigger this requirement because no tax is withheld on self-employment income.

Question 6

What is the marginal tax rate on my side hustle?

Accepted Answer

Your side hustle income is taxed at your marginal rate — the rate on the last dollar of income. Since it stacks on top of your employment income, it is taxed at a higher rate than if it were your only income. For example, if your employment pushes you into the 29% federal bracket, all side hustle income is also taxed at 29% or higher federally.

Question 7

Can I use side hustle losses to reduce employment tax?

Accepted Answer

Yes, business losses from a legitimate side hustle can offset employment income, reducing your overall tax. However, CRA may challenge repeated losses if the business shows no reasonable expectation of profit. If CRA reclassifies the activity as a hobby, the losses will be disallowed.
