Frequently Asked Questions
Self-employed Mississauga residents must file a T1 personal income tax return and attach Form T2125 (Statement of Business or Professional Activities) to report their self-employment income and expenses. If your annual self-employment revenue exceeds $30,000, you must also register for HST and file regular HST returns with the CRA.
Common deductible expenses for Mississauga self-employed individuals include: home office expenses (T2200), vehicle and travel expenses, professional fees, advertising and marketing, business insurance, equipment and supplies, phone and internet (business portion), and subcontractor payments. Our Mississauga tax team ensures you claim every legitimate deduction to minimize your tax liability.
Yes. If you owe more than $3,000 in taxes in the current year (or either of the two previous years), CRA will require you to make quarterly income tax instalments. Instalment due dates are March 15, June 15, September 15, and December 15. Our Mississauga accountants help you calculate the correct instalment amounts to avoid interest charges.
Self-employed individuals and their spouses/common-law partners have until June 15 to file their T1 personal tax returns. However, any taxes owing are still due by April 30. If you miss the April 30 payment deadline, CRA will charge interest on amounts owing. Our Mississauga team helps you plan ahead and avoid late-payment interest.
