Top CRA-Approved Tax Deductions for Canadian Small Business Owners

What Can You Deduct as a Small Business Owner in Canada?

Tax season doesn’t have to be stressful — especially if you know your eligible write-offs. As a Canadian small business owner, the Canada Revenue Agency (CRA) allows you to deduct certain business expenses to reduce your taxable income and keep more money in your pocket.

If you work from home, you can claim a portion of your:

1. Rent or mortgage interest
