Legal fees can run into thousands of dollars quickly, yet the Canada Revenue Agency only allows a deduction in a narrow set of circumstances. Whether you can write off what you paid your lawyer depends entirely on the purpose of the legal work — not the amount, not the outcome. Understanding the distinction between deductible and personal legal costs before you file can save you a meaningful amount of tax, and avoiding a mistaken claim keeps you clear of a CRA reassessment.
CRA's position on legal fees flows from section 8, section 18, and paragraph 60(o.1) of the Income Tax Act, and is consolidated in Interpretation Bulletin IT-99R5 (Legal and Accounting Fees). The guiding principle is straightforward: a legal expense is deductible only if it was incurred for the purpose of earning income from employment, business, or property — or to establish or enforce a legal entitlement to income that is itself taxable.
Purely personal legal costs — even ones that feel financially significant, such as a divorce, buying a home, or defending a criminal charge — do not meet this test and are not deductible under any line of the T1 return.
Employees can claim legal fees at line 22900 (Other employment expenses) of the T1 when fees were paid to collect or establish a right to salary or wages owed by an employer or former employer. This covers situations such as wrongful dismissal litigation, pursuing unpaid commissions, or disputing a denied bonus where the amount at issue forms part of your employment income.
The deduction at line 22900 is limited to the amount of employment income (and taxable retiring allowances) you actually recovered or received in the year or a preceding year, less any reimbursement you received from the employer. You cannot use employment legal fees to create or increase a loss. Any unused amount can be carried forward up to seven years.
Keep your retainer invoices and fee statements. CRA may request documentation showing the legal matter related directly to recovering employment income. A general invoice for "legal services" is often insufficient on audit — ask your lawyer to describe the matter on the invoice.
Legal fees paid to establish or enforce the right to receive child support or spousal support are deductible at line 22100 (Carrying charges and interest expenses). This is one of the few areas where family law intersects with tax deductions.
The logic here is that child and spousal support received by the recipient is not taxable income under current rules (post-1997 agreements), yet CRA has confirmed through administrative policy that the fees to establish that right remain deductible. The payor side, by contrast, receives no deduction for legal fees to resist or reduce support obligations.
For self-employed individuals and rental property owners, legal expenses are simply a cost of earning income and are generally deductible in full — provided they relate to the income-earning activity and are not capital in nature.
Legal fees incurred to purchase or sell a capital property — such as a rental building, commercial real estate, or shares — are not currently deductible. Instead, they form part of the adjusted cost base (ACB) on purchase, or reduce the proceeds of disposition on sale. This distinction matters when calculating capital gains: tracking those legal costs correctly can lower the taxable gain by a meaningful amount, particularly on real estate transactions where legal fees routinely exceed $2,000–$5,000 CAD.
The following costs are personal expenditures in CRA's view and do not qualify for any deduction on your T1 return:
| Legal Fee Scenario | Deductible? | CRA Line / Form | Key Condition |
|---|---|---|---|
| Suing former employer for unpaid wages ($8,400 in fees) | Yes | Line 22900 | Limited to wages recovered |
| Obtaining spousal support order ($3,200 in fees) | Yes | Line 22100 | Recipient only; not payor |
| Enforcing child support arrears ($1,900 in fees) | Yes | Line 22100 | Enforcement or variation upward |
| Contract drafting for self-employed consultant ($2,600) | Yes | T2125 — Fees | Current business expense |
| Evicting non-paying tenant ($1,450 in fees) | Yes | T776 — Legal | Rental income-earning purpose |
| Legal fees to purchase a rental property ($4,100) | No* | Add to ACB | *Capital; reduces gain on sale |
| Divorce proceedings — no support claim ($6,500) | No | Not deductible | Personal expenditure |
| Criminal defence related to business ($12,000) | No | Not deductible | IT-99R5 para. 22 |
| Appealing a CRA income tax reassessment ($5,000) | No | T1-ADJ for errors | Explicitly excluded by ITA |
| Will preparation and estate planning ($900) | No | Not deductible | Personal/capital purpose |
If you are self-employed, you are in the most advantageous position for legal fee deductions. Any legal cost that is ordinary and reasonable in the context of running your business is deductible on the T2125. This includes retainer fees, hourly charges, and disbursements. The only ceiling is the reasonableness test under section 67 of the Income Tax Act — CRA can challenge fees that appear excessive relative to the nature of the business matter.
For incorporated businesses, legal fees are deducted at the corporate level on the T2 return under professional fees. The corporation's after-tax cost of that legal work is therefore lower than for an unincorporated individual — one of several reasons the Calgary team at Swift Accounting Ltd. often walks owner-managers through the incorporation decision when legal and professional costs are a regular part of operations.
Legal fee deductibility is one of the areas where a single incorrect claim can trigger a review, and one correct claim can recover real money that would otherwise go untouched. If you paid significant legal fees in the 2024 or 2025 tax year and are unsure which category they fall into, the team at Swift Accounting Ltd. can review the circumstances and ensure the right deduction is claimed on the right line.
