We provide specialized accounting and tax services to support marketing, management, engineering, and technology consulting firms across Ontario from our Toronto and Oakville offices.
Whether you need a full-service accounting firm for your consulting business, a tax specialist for your corporation, or advisory services to accelerate growth, we’re here to help.
Here are a few reasons Toronto consultants choose Cassar CPA:
Consultants often incur expenses like professional dues, business insurance, home office use, travel, and marketing. CRA allows deductions for consulting fees, accounting & legal professional fees, and business-use-of-home expenses, among others. Cassar CPA helps you maximize allowable deductions under these rules.
Depending on your income level, liability exposure, and growth plans, operating as a Canadian-controlled private corporation (CCPC) or staying as a sole proprietor may make a difference. Cassar CPA assesses your situation, giving advice on structure, tax efficiency, and how to plan ahead.
We provide bookkeeping, income tax (personal / corporate), HST/GST compliance, financial reporting, and advisory, tailored to consulting workflows. As you scale, costs rise, cash flow gets tight; our systems and tools help you stay organized, compliant, and informed.
At Cassar CPA, we believe consulting professionals need more than just financial records, they need clarity, strategic tax planning, and strong financial foundations. We combine our Ontario regulatory expertise with hands-on service and technology tools, to ensure your consulting business remains compliant, efficient, and positioned to scale.
We’ll review your business model: how you invoice (contracts, hourly, retainer), where clients are located, whether you have contractors or employees, current expense and accounting systems.
If needed, help you clean up bookkeeping, separate business vs personal expenses, set up business-use-of-home expenses, manage software/subscription costs, organize receipts and documentation, clear up outstanding income tax or GST/HST issues.
Includes financial statements, monthly or quarterly bookkeeping, corporate/personal tax return preparation, managing HST/GST, tracking contractor or employee payroll, managing deductible expenses, tracking travel/vehicle/use of home, etc.
We stay current with any CRA or Ontario tax rule changes affecting consultants, offer advice on cash flow forecasting, tax planning, and help you prepare for growth (for example, when to register for GST/HST, when to incorporate, when clients’ contracts change).

You can generally deduct professional fees, business insurance, home office costs (utilities, internet, rent, maintenance proportionate to space used), travel or vehicle costs (for business), marketing or advertising, subscriptions or software. Cassar CPA ensures that documentation and classification meet CRA requirements.
If your total taxable revenues exceed the small supplier threshold (currently $30,000 in the last four consecutive calendar quarters), you will need to register for, collect, and remit GST/HST. Cassar CPA helps you monitor revenue levels, decide timing, and manage compliance.
That depends on factors like your income, how many clients or contracts you serve, liability exposure, and your growth plans. Incorporation can offer advantages in tax deferral, income splitting, and regulatory protections, but comes with costs and formalities. Cassar CPA assists in making the decision grounded in your circumstances.
Yes, as long as part of your home is used regularly and exclusively for business. You can claim a portion of utilities, property taxes, rent/mortgage interest, maintenance proportional to the business-use area. Cassar CPA helps establish your eligible space and ensures proper record-keeping.
Fees paid for external professional advice (legal, accounting, other consulting) are generally deductible, as are costs of maintaining accounting records, preparing and filing tax returns, or business licenses and dues. Cassar CPA ensures they are properly accounted for.
