Paying a spouse or family member from a contractor’s corporation is common, and often legitimate: many incorporated contractors have a spouse who genuinely handles invoicing, scheduling, or bookkeeping tasks the contractor does not have time for. The arrangement is not inherently risky. What CRA looks at when it reviews a family wage is whether the work actually happened and whether the amount paid reflects what that work is worth, not whether paying a spouse is permitted in principle.
The Two Questions That Actually Matter
Every family wage arrangement comes down to two separate questions: did the person do real work for the corporation, and was the amount paid reasonable for that work. Both have to hold up independently. A spouse who genuinely handles two hours of invoicing and scheduling a week but is paid a full-time administrative salary fails the reasonableness question even though the work is real. A spouse paid a modest, defensible hourly rate for work that was never actually performed fails the first question even though the amount looks reasonable on paper.
What Counts as Reasonable
Reasonableness is measured against what an arm’s length person doing the same work, at the same time commitment, would be paid in the local market. Comparable rates for bookkeeping support, scheduling, client correspondence, or general administrative work are the relevant benchmark, not the contractor’s own billing rate for technical services and not the family’s overall desired income split for the year.
The amount also has to track the actual hours or scope of work. A spouse handling occasional invoicing on an as-needed basis supports a modest part-time wage. A spouse who has effectively become the business’s operations manager, managing client scheduling, bookkeeping, and correspondence on a near-daily basis, supports a higher, more substantial wage. The mismatch CRA most often identifies is a wage level that assumes far more work than the documented facts support.
Payroll Mechanics Apply the Same Way
A spouse paid wages by the corporation is an employee of the corporation for payroll purposes, with no exception for the family relationship. This means the wage is processed through payroll or accrued like any other employee’s compensation, subject to CPP contributions and, where the employment relationship is not exempt, EI considerations, with source deductions remitted and a T4 issued at year-end.
Paying a spouse informally, outside payroll, or issuing a T4 without the corresponding remittances does not satisfy this requirement. A wage arrangement that is not run through proper payroll mechanics is a compliance gap independent of whether the underlying work and amount would otherwise have been defensible.
Why This Is Not a TOSI Question
Tax on split income targets dividends and certain other amounts paid to a related individual in respect of shares they hold in a private corporation, not payroll wages paid for genuine services rendered. A reasonable salary for real work does not fall within what TOSI is designed to catch, and reasonable salary income itself is a recognized basis that can support an exemption from TOSI where dividends are also being considered for the same family member.
The exposure with a spouse’s wage sits elsewhere: CRA can deny the deduction outright, or reassess the amount down to what it considers reasonable, if the wage does not correspond to real, documented work at a defensible rate. This is a reasonableness-of-expense question under ordinary deductibility principles, separate from the TOSI framework that applies to dividends and other share-based amounts.
Documentation to Keep
- A description of the work the spouse or family member actually performs for the corporation
- An approximate log of hours worked, or a consistent recurring task list if hours vary
- The hourly or salary rate used, and a basis for comparing it to what an unrelated person doing the same work would be paid
- Standard payroll records: T4 slips, source deduction remittance confirmations, and any employment agreement or offer letter
- Any change in scope of work over time, since a wage increase should correspond to a documented increase in responsibilities or hours
Common Mistakes
Paying a round, convenient number instead of a rate tied to actual work. A wage set to use up available corporate cash or hit a target income split, rather than reflecting hours and market rate, is the pattern CRA is most likely to challenge.
Treating the arrangement as informal because it is a family member. Payroll obligations, T4 reporting, and documentation requirements apply the same way regardless of the employee’s relationship to the owner.
Setting the wage once and never revisiting it as the scope of work changes. A rate that made sense when the spouse handled occasional invoicing should not carry forward unchanged if the role has grown into something closer to full-time administrative support, or should scale back down if the work has shrunk.
