1. Introduction: Contractors and Tax Challenges
Contractors in Ottawa face unique tax challenges. Unlike employees, they manage their own income, expenses, and tax remittances. Without proper planning, contractors can end up paying more than necessary.
At BBA Tax, we help contractors reduce their tax burden through strategic planning, proper bookkeeping, and CRA-compliant deductions, ensuring maximum take-home pay.
2. Understanding Taxes for Contractors in Canada
Contractors are usually considered self-employed, meaning they’re responsible for:
- Income tax on business and personal earnings
- CPP contributions on self-employment income
- GST/HST collection and remittance (if over $30,000 in revenue)
Taxes are calculated on net income, so maximizing deductions is critical.
3. Track All Eligible Business Expenses
Deductible expenses directly reduce taxable income. Common contractor deductions include:
- Office rent and utilities (home-office portion if applicable)
- Supplies, tools, and equipment
- Vehicle costs (gas, maintenance, insurance)
- Internet, phone, and software subscriptions
- Professional fees (accountants, legal advice)
- Training or certifications
Tip: Keep receipts and detailed records — the CRA can request proof during an audit.
4. Incorporation vs Sole Proprietorship
Many contractors benefit from incorporating their business:
- Lower small-business tax rate on profits (~12.2% in Ontario 2025)
- Ability to defer taxes by retaining earnings in the corporation
- Limited liability protection
- Potential for income splitting with family members
A sole proprietorship is simpler but often results in higher personal tax rates. Consult an accountant to see which structure suits your goals.
5. Pay Yourself Strategically: Salary vs Dividends
If incorporated, contractors can choose how to pay themselves:
Salary:
- Deductible to the corporation
- Contributes to CPP and RRSP room
Dividends:
- Taxed at a lower rate personally
- No CPP contributions
A blended approach often minimizes total taxes while keeping retirement contributions intact.
6. Use Registered Accounts to Reduce Taxable Income
Registered accounts can reduce or defer taxes:
- RRSPs: Contributions reduce taxable income immediately
- TFSAs: Growth is tax-free and withdrawals aren’t taxed
- RESPs: Tax-sheltered education savings for children
Properly timing contributions and withdrawals can significantly reduce your 2025 tax liability.
7. Plan for GST/HST Obligations
If your business earns over $30,000, you must register for GST/HST:
- Collect tax from clients
- Remit to CRA quarterly or annually
- Claim input tax credits for GST/HST paid on business purchases
Proper planning prevents penalties and ensures maximum deductions.
8.CRA Compliance and Audit Considerations
The CRA monitors self-employed individuals closely. Common triggers for audits include:
- Large or unusual deductions
- High expenses relative to revenue
- Inconsistent income reporting
BBA Tax Ottawa helps contractors maintain accurate records, file on time, and defend against audits, reducing risk and stress.
