Sole proprietors report business income and expenses on Form T2125 (Statement of Business or Professional Activities), which is included with their T1 personal income tax return. You pay personal income tax on your net business profit at your marginal rate. Our Mississauga accountants ensure all allowable deductions are claimed to minimize your tax.
Common deductions include home office expenses, vehicle costs (business-use portion), advertising, professional fees, supplies, phone and internet, insurance, bank charges, and CCA on business assets. The key is that expenses must be incurred to earn business income. We help identify every eligible deduction for your specific business.
You must register for HST when your annual revenue exceeds $30,000 in any single calendar quarter or in four consecutive quarters. We recommend voluntary registration in some cases to recover input tax credits. We handle HST registration, filing, and planning for sole proprietors throughout Mississauga and Ontario.
Incorporation may benefit you if your net business income exceeds approximately $100,000–$150,000, you want liability protection, or you want to defer personal taxes. We analyze your specific situation and provide a clear comparison of sole proprietorship vs. corporation to help you make the right decision.
