Introduction Effective tax planning is essential for the financial health of any small business, especially in a competitive and regulated environment like Ontario. Strategic decisions made throughout the year can reduce your tax burden and improve profitability. At STS CPA Professional Corporation, we specialize in helping Ontario businesses navigate tax laws and maximize their savings. Here’s a detailed guide to the top tax-saving strategies you can apply in 2025.
Incorporate Your Business Incorporating your business provides access to the small business deduction (SBD), which reduces the corporate tax rate on the first $500,000 of active business income. In Ontario, incorporated businesses may pay combined federal and provincial tax rates as low as 12.2%, compared to personal marginal rates that can exceed 50%. Incorporation also enables income deferral and tax planning flexibility.
Pay Yourself Strategically Choosing between salary and dividends can significantly affect your tax liability. Salaries are tax-deductible business expenses and contribute to CPP, while dividends are taxed at a lower personal rate but do not contribute to CPP. A blended approach often works best, and STS CPA can help determine the ideal balance for your situation.
Deduct Business Expenses Eligible business expenses reduce your taxable income. Common deductions include:
- Office rent and utilities
- Vehicle mileage or lease
- Business-related travel and meals
- Marketing and advertising
- Professional services and subscriptions
Maintaining accurate records and receipts is critical for CRA compliance. Digital accounting software or professional bookkeeping services from STS CPA can simplify this process.
Leverage the Small Business Deduction (SBD) For 2025, Canadian-controlled private corporations (CCPCs) can access the SBD on their first $500,000 of taxable active business income. This reduces the federal tax rate to 9%, with Ontario adding a provincial rate of 3.2%, totaling 12.2%. This substantial tax break can result in thousands of dollars in annual savings.
Use a Home Office Deduction If you run your business from home, you may be eligible to deduct a portion of your household expenses. This includes:
- Rent or mortgage interest
- Utilities
- Property taxes
- Internet
To qualify, the workspace must be used regularly and exclusively for business. The claimable portion is typically calculated based on square footage or number of rooms.
Take Advantage of Capital Cost Allowance (CCA) CCA allows you to depreciate the value of business assets over time. Common assets include computers, furniture, and vehicles. Each asset falls under a specific class with prescribed rates:
- Class 8: Office furniture (20%)
- Class 10: Vehicles (30%)
- Class 50: Computer hardware (55%)
Strategic timing of purchases and CCA claims can help reduce taxable income effectively.
Defer Income Strategically If your business anticipates lower income in the following year, it may be beneficial to defer invoicing or delay income recognition until then. This can help manage your tax bracket. Be cautious not to violate accrual accounting principles, and consult with an STS CPA professional before deferring income.
Split Income with Family Members Paying family members a reasonable salary for legitimate work can reduce overall family taxes. Be aware of the Tax on Split Income (TOSI) rules, which can negate the benefits unless specific conditions are met. Document job roles and payments thoroughly to stay CRA-compliant.
Contribute to a Registered Retirement Savings Plan (RRSP) RRSP contributions reduce your personal taxable income and defer taxes until retirement. Business owners can benefit from RRSPs especially when withdrawing salary. The 2025 RRSP contribution limit is $31,560 or 18% of earned income, whichever is lower.
Stay on Top of Tax Deadlines Missing filing deadlines can result in penalties and interest. Key CRA dates include:
- T2 Corporate Tax Return: 6 months after fiscal year-end
- HST Returns: Quarterly or annually, depending on election
- Payroll remittances: Monthly or semi-monthly
Using automated reminders or working with a CPA ensures nothing slips through the cracks.
