Home Office Expenses
If your principal place of business is your home, you can deduct a proportional share of utilities, mortgage interest or rent, property taxes, home insurance, and maintenance. The CRA requires the space be used exclusively and regularly for work. Proper calculation and documentation is critical — Swift Accounting ensures your claim survives a review.
🚗
Vehicle Expenses
Business-use vehicle costs are deductible: fuel, oil changes, repairs, insurance, licensing, parking, and Capital Cost Allowance (CCA) on the purchase price. You must maintain a vehicle log showing business-versus-personal kilometres. We structure your vehicle claims to maximize the deduction while staying within CRA guidelines — avoiding the red flags that trigger reviews.

Tools, Equipment & CCA
Tools, equipment, computers, and other capital purchases are deducted through the Capital Cost Allowance (CCA) system over multiple years — or, for eligible equipment, accelerated under the Immediate Expensing rules that allow full first-year deduction. Understanding which CCA class applies to each asset class is critical; misclassification creates headaches at reassessment time.

Meals & Entertainment
Business meals and client entertainment are 50% deductible under the Income Tax Act. To be claimable, the expense must have a legitimate business purpose and you must record who attended and what business was discussed. Long-haul transport exceptions aside, keep receipts and notes for every meal claimed — the CRA scrutinizes this category closely for contractors.
📋
Professional Fees & Licensing
Accounting fees, legal costs, professional association dues, trade licensing fees, and professional liability insurance are all fully deductible business expenses for contractor corporations. These are among the most defensible deductions — properly documented, they are almost never challenged.
👥
Subcontractor Payments
Payments made to subcontractors are deductible as business expenses — but must be supported by T4A slips (for amounts over $500) and proper contracts. Using subcontractors also strengthens your position against PSB classification by demonstrating that your corporation operates as a genuine business entity, not a single-employee "incorporated employee."
📚
Training & Professional Development
Courses, certifications, industry conferences, and educational materials directly related to your trade or profession are deductible. Upgrading skills that maintain or improve current employment capabilities qualifies — courses for an entirely new career line generally do not. The distinction matters at audit time.
💰
Salary–Dividend Optimization
Owner-operators of contractor corporations can pay themselves a combination of salary (deductible to the corporation, generates RRSP room) and dividends (taxed at preferential rates). The right split changes every year as your income level and corporate profit change. Swift Accounting calculates the optimal compensation structure annually so you always pay the lowest combined personal and corporate tax.
🛡️
Business Insurance
General liability, professional indemnity, errors and omissions, and contractor-specific insurance premiums are fully deductible business expenses. Insurance also plays a role in PSB analysis — carrying your own business insurance demonstrates financial independence from your clients and is one of the indicators the CRA looks for in a genuine independent contractor relationship.
