We provide specialized accounting and tax services to support law firms, solo practitioners, and legal professionals across Ontario from our Toronto and Oakville offices.
Whether you need a full-service accounting firm for your law firm, bookkeeping support for your law practice, or a tax specialist for your professional corporation, we’re here to help.
Here are a few reasons why legal professionals in Toronto partner with Cassar CPA:
We know the rules for professional corporations for lawyers in Ontario, including Law Society of Ontario requirements. Cassar CPA helps structure your practice (solo, partnership, or corporation) in the most tax-efficient and compliant way.
Lawyers have expense categories like continuing legal education, professional dues, insurance, rent, office overhead, trust accounting, marketing, and tools. We ensure you claim what you’re entitled to under CRA rules, and avoid pitfalls. Clio’s “Top Tax Deductions for Lawyers” list includes many of these.
Legal billing often involves disbursements, HST treatment, and timing of remittances. Cassar CPA ensures your invoices, trust accounts, and disbursements are handled properly so you comply with CRA and Law Society guidance. For example, lawyers in Ontario must register and collect HST when fees/disbursements exceed thresholds.
At Cassar CPA, we believe law firms deserve more than just financial statements. Your practice needs an accountant who understands WIP valuation, professional-corporation rules, disbursement vs fee billing, trust accounting, and the specific compliance demands of the legal profession. That’s why we deliver accounting, tax, and regulatory support tailored for lawyers so you can focus on justice, practice development, and client service while we handle the financial complexity with rigor and reliability.
Here’s how Cassar CPA supports your law firm:
We’ll review your current business structure, revenue sources (billable hours, fees, disbursements), unpaid work-in-progress (WIP), trust accounting, and your practice’s tax profile.
If you operate as a professional corporation, partnership, or sole proprietor, we help with set up or review of your ownership, director/shareholder rules, and professional compliance. We also help establish strong bookkeeping, financial reporting, and systems for tracking WIP and receivables.
Includes updating financial statements, corporate or personal tax returns, payroll (if applicable), trust account reconciliation, HST/GST remittances, expense tracking, and ensuring overhead, professional dues, insurance, etc., are properly accounted for.
We stay on top of changes from CRA, the Law Society of Ontario, and other legal/regulatory bodies. We monitor updates in professional corporation rules, tax law (including with respect to WIP, passive income inside PCCs), as well as audit readiness and best practices so you avoid regulatory or tax risks.

It depends on revenue levels, risk, ownership structure, income splitting opportunities, WIP, and how you want to manage liability and taxes. Cassar CPA reviews your situation, including professional corporation rules enforced by the Law Society of Ontario, to help you make the best decision.
Common deductions include professional dues, continuing education, malpractice or liability insurance, rent and utilities, office overhead, software and research tools, marketing, travel for court or clients. Cassar CPA ensures they’re eligible under CRA rules and properly documented.
WIP represents unbilled work at year-end; it needs to be included in income under current tax laws. Cassar CPA helps measure, value, and report WIP properly so your firm meets CRA requirements.
Lawyers must clearly show fees and disbursements, separately list HST, register with CRA if applicable, and follow rules for disbursements (e.g. kinds of expenses considered disbursements vs billable). Cassar CPA can help set up invoicing, trust accounting, and ensure you follow tax and regulatory standards.
Trust funds must be properly recorded, reconciled, with clear separation from general accounts. Lawyers often hold retainers, settlement funds, or client security in trust; these need strong systems, proper bookkeeping, and compliance with Law Society & CRA rules. Cassar CPA supports you in setting up and maintaining trust accounting systems.
