- HST on legal fees: Legal services are taxable — charge 13% HST in Ontario once registered (after $30,000 threshold).
- Partnership income: Partners report their share of firm income on T5013; draws are not wages and no deductions are withheld.
- WIP election: Designated professionals (lawyers, accountants) can exclude unbilled work-in-progress from annual income — but 2017 budget changes restrict this; verify current rules with your advisor.
- LPC incorporation: Law Professional Corporations allow tax deferral at ~12.2%; Law Society rules require lawyers to hold voting shares.
- Deductions: Bar dues, continuing legal education, malpractice insurance, law library, robes, and travel are deductible.
- Quarterly instalments: Partners must make quarterly instalment payments — no payroll withholding occurs on partnership draws.
How Lawyers Are Taxed: Four Common Structures
| Structure | Tax Status | Income Reported On | CPP |
|---|---|---|---|
| Law firm employee (associate) | Employment income | T4 → T1 Line 10100 | Employer withholds at source |
| Partner in law firm | Self-employment / partnership | T5013 → T1; CPP on net SE income | Self-pay both sides via Schedule 8 |
| Solo practice (unincorporated) | Self-employment | T2125 → T1 Line 13700 | Self-pay both sides via Schedule 8 |
| Law Professional Corporation | Corporate + personal | T2 for corp; T4/T5 for owner | On salary component only |
HST on Legal Services
Unlike healthcare services, legal services are fully taxable for HST purposes. Once your annual revenues exceed $30,000, you must register for HST and charge 13% in Ontario (or the applicable rate in other provinces).
What is taxable?
- Professional fees for legal advice, drafting, and representation — all taxable
- Paralegal fees for court appearances, legal document preparation — taxable
- Legal consulting and contract review — taxable
What about disbursements?
Disbursements are amounts you pay on behalf of clients and recover (court filing fees, title search fees, etc.). Their HST treatment depends on structure:
| Disbursement Type | HST Treatment |
|---|---|
| HST-exempt disbursements (court filing fees, government fees) | Pass-through at actual cost; no HST added |
| HST-taxable disbursements (photocopies, courier) | Add HST to recovery amount; claim ITC on cost |
| Disbursements charged as part of your service (overhead) | HST applies on the full amount |
Partnership Income: Draws, Allocations, and T5013
Partners in a law firm are not employees. Key distinctions:
- Draws: Regular withdrawals against your anticipated share of profits. Draws are not wages — no CPP or income tax is withheld.
- Partnership income: At year-end, the firm allocates profits and losses to each partner based on the partnership agreement.
- T5013 slip: The firm issues a T5013 (Statement of Partnership Income) showing your allocated share.
- T1 reporting: Your T5013 income is reported on Schedule 4 and flows into your T1 as professional income (Line 13700).
- CPP: Partners pay CPP on their net self-employment income via Schedule 8 — both employee and employer portions.
Partners must distinguish between their capital account (their equity stake in the firm) and income account (allocated profits). Draws against capital are generally not income. Draws against allocated profits are income when the profits are allocated, not necessarily when the draw is taken. Maintain clear partnership accounting to ensure accurate tax reporting.

The Work-in-Progress (WIP) Election
Lawyers are designated professionals under the Income Tax Act. Historically, designated professionals could elect to exclude the fair market value of work-in-progress (unbilled services) from annual income. The 2017 federal budget significantly limited this election — it now applies only to a professional's last fiscal year before retirement or death, and only under specific circumstances.
Before the 2017 budget, many lawyers and other designated professionals used the WIP election to defer income by excluding the value of unbilled files. This deferral is now generally unavailable for ongoing practices. Work performed is generally includable in income when the services are performed, not just when billed. Get advice from a tax professional who specializes in professional practices on your income recognition timing.
Law Professional Corporations (LPCs)
Ontario permits lawyers to incorporate as Law Professional Corporations. Rules:
- At least one lawyer licensee must hold all voting shares (non-voting shares may be held by others)
- The LPC must be a professional corporation meeting LSO requirements
- The LPC pays corporate tax at small business rates (~12.2% in Ontario on the first $500,000)
- Tax on Split Income (TOSI) rules significantly limit income splitting through dividends to non-lawyer family members
- Incorporation does not shield lawyers from professional liability to clients
| Scenario | $250,000 Net Professional Income | Approximate Tax |
|---|---|---|
| Unincorporated lawyer (personal) | Ontario top rate ~53.53% above $246,752 | ~$110,000 |
| Incorporated LPC (retaining income in corp) | ~12.2% corporate tax on retained amount | ~$30,500 (+ personal tax when withdrawn) |
| Tax deferral saving | ~$79,500 stays inside LPC for investment | Taxed when withdrawn as dividends |
Paralegal Tax Considerations
Paralegal licensees in Ontario can provide legal services in specific areas (Small Claims Court, provincial offences, certain Tribunal proceedings). Their tax treatment differs slightly:
- HST applies to paralegal fees in the same way as lawyer fees — register once revenues exceed $30,000
- Self-employed paralegals report income on Form T2125
- Paralegal corporations are permitted in Ontario — similar structure to LPCs
- Professional liability insurance (required by LSO) is fully deductible
- Law Society Paralegal annual fee is fully deductible
