CRA Denies Legal Fee Deduction When You Pay Someone Else's Bill

When taxpayers pay legal fees for someone else's tax dispute, the CRA typically disallows the deduction. The person claiming the deduction must be legally obligated to pay the bill and must be the direct beneficiary of the legal services. Voluntary payment of someone else's debt, even when the underlying legal matter touches the taxpayer's financial interests, is generally considered a personal expense.

The Income Tax Act allows deductions for legal fees incurred to earn income from a business or property. The critical word is "incurred." The CRA interprets this to mean the taxpayer claiming the deduction must be the person legally obligated to pay the bill and the direct beneficiary of the legal services. Voluntary payment of someone else's debt, even when the underlying legal matter touches the taxpayer's financial interests, is considered a personal expense.

The Tax Court has held that taxpayers generally cannot deduct legal fees paid on behalf of others. A shareholder cannot deduct legal fees paid on behalf of their corporation, even when the corporation's survival directly affects the shareholder's income. A spouse cannot deduct fees paid to defend the other spouse in a tax audit, even when the couple files jointly and shares the financial consequences. The nexus between the expense and the taxpayer's own income must be direct, not incidental.

The Purpose Test Governs Everything

The CRA applies what it calls the "purpose test" to every legal fee claim. The question the CRA asks is: why did this specific taxpayer incur this specific expense? Reasonableness does not matter. Protection of wealth does not matter. Prevention of a worse outcome does not matter.

If the legal matter pertains to a third party, a child, a partner, a separate legal entity, the connection to the taxpayer's income production is treated as too remote. Section 60(o) of the Income Tax Act does allow deductions for fees paid to contest a tax assessment, but only when the assessment was issued to the taxpayer claiming the deduction. Paying to fight someone else's assessment, even a family member's, does not qualify.

The Tax Court has ruled that even when a taxpayer has indirect financial exposure, legal fees paid for another person's tax dispute are not deductible. If legal services are rendered to a family member and the payer's financial exposure is considered hypothetical or secondary, the CRA will deny the deduction.

Structuring Matters More Than Intent

To make legal fees deductible, the retainer agreement and the invoice must name the taxpayer who intends to claim the deduction. The legal matter must relate to that person's own income-earning activities, not someone else's. If a corporation pays legal fees for a shareholder's personal tax dispute, the CRA will reclassify the payment as a taxable shareholder benefit rather than a deductible corporate expense.

There is a narrow exception when the taxpayer can prove they acted as a formal agent for the other party, but this requires a written agency agreement executed before the legal services were retained. The CRA will not accept a retroactive agreement signed after the lawyer's work began.

The practical consequence is that paying a family member's or business associate's legal fees to protect shared wealth produces no tax benefit. The payer gets no deduction. The recipient, who did not pay the bill, gets no tax relief either. Money spent on someone else's tax dispute may resolve the underlying issue, but it provides no relief from the tax system.
