Under Section 67 of the Income Tax Act, the Canada Revenue Agency (CRA) will only allow a business to deduct a family member’s salary if the amount is “reasonable” for the work performed. If you pay a spouse $80,000 CAD annually for minimal administrative tasks, the CRA may deny the deduction, leading to severe tax penalties and double taxation. Defending this requires solid documentation and often a tax lawyer.
Running a family business in Canada is a proud tradition, but it comes with intense federal scrutiny. Many small business owners in cities like Toronto, Calgary, and Vancouver choose to hire their spouses or children to help with operations. While this is a completely legal and effective way to manage a company, the Canada Revenue Agency (CRA) often flags these payroll deductions for an audit to ensure you are not improperly splitting income to lower your household tax burden.
When an auditor reviews your corporate tax return, they apply the “reasonableness test.” They want to know exactly what the family member did to earn that money and whether you would have paid a stranger the same amount for the same work. If the CRA decides the salary is inflated, they will reassess your taxes, charge interest, and potentially apply gross negligence penalties. Understanding how to defend your payroll decisions is essential to protecting your business’s financial health.
Step-by-Step Process for Defending a Salary Audit in Canada
Because the CRA operates federally, the rules governing family salaries and the Income Tax Act are identical whether your business is based in Nova Scotia or British Columbia. Successfully navigating an audit requires meticulous preparation and a clear strategy.
Step 1: Understand the Section 67 Reasonableness Test
The foundation of your defence lies in Section 67 of the Income Tax Act. This rule simply states that no deduction shall be made for an expense unless it is reasonable in the circumstances. Your first step when notified of an audit is to objectively review the salary paid to your family member. Would you pay an independent third-party the same wage for identical duties? If the answer is yes, you have a strong starting point.
Step 2: Formalise the Job Description
📄 The CRA will immediately ask for proof of work. You must be able to provide a detailed, written job description for your spouse or child. This document should outline their daily responsibilities, required skills, and the time commitment expected. “Helping out around the office” is not a valid job description. You need specifics, such as “managing social media accounts 15 hours a week” or “handling all Accounts Receivable using QuickBooks.”
Step 3: Provide Evidence of Work Performed
Having a job description is not enough; you must prove the work was actually completed. Gather all available evidence. This includes timesheets, emails sent from the family member’s company address, client correspondence, logbooks, and project files. The more digital or physical footprints they left while working, the easier it is to satisfy the CRA auditor.
Step 4: Benchmark the Salary to Market Rates
To prove the salary is reasonable, you must provide market comparables. You can use federal resources like the Job Bank of Canada to find the average hourly rate for similar positions in your specific city or province. For example, if the average bookkeeper in Ottawa earns $25 CAD per hour, paying your spouse $25 to $30 CAD per hour is highly defensible. Paying them $100 CAD per hour is an immediate red flag.
Step 5: Ensure Proper Payroll Deductions Were Made
The CRA will check if you treated your family member like a legitimate employee. You must prove that you issued regular paycheques and remitted the correct source deductions (Income Tax and Canada Pension Plan). Note that spouses and children working in a family business are often exempt from Employment Insurance (EI) premiums if they do not deal at “arm’s length,” but you should have a formal CRA ruling to confirm this.
Step 6: Reply to the Proposal Letter
📧 If the auditor remains unconvinced, they will issue a “Proposal Letter” outlining their intent to disallow the salary deduction. You generally have 30 days to respond. At this stage, it is highly recommended to have a Canadian tax lawyer draft a formal submission. Your legal team will present the evidence of work and cite previous Tax Court of Canada decisions supporting your position.
Step 7: File a Notice of Objection
If the auditor finalises the reassessment and denies the deduction, you will receive a Notice of Reassessment. You then have 90 days to file a formal Notice of Objection. This moves your file away from the original auditor and sends it to the CRA’s independent Appeals Division for a completely fresh review.
How Much Does it Cost in Canada?
💰 Defending against a CRA audit involves professional fees, but these costs are often much lower than the massive tax bills and penalties you would face if you lose.
- Initial Accountant Review: Having your CPA compile the initial audit documents usually costs between $1,000 and $2,500 CAD.
- Tax Lawyer Representation: Hiring a law firm to manage the audit communication and draft a response to a proposal letter typically ranges from $3,500 to $7,000 CAD.
- Filing a Notice of Objection: If the case escalates to the Appeals Division, legal fees generally range from $5,000 to $10,000 CAD depending on the complexity of the file.
- Tax Court of Canada: Taking the CRA to court is a last resort and can easily exceed $20,000 CAD in legal fees.
How Long Does the Process Take?
⏳ CRA audits move slowly. Resolving a dispute over family wages requires patience and strict adherence to government deadlines.
| Phase of CRA Dispute | Estimated Timeline | Key Considerations |
|---|---|---|
| Initial Audit Period | 3 to 6 Months | The time between providing your documents and receiving a decision. |
| Proposal Letter Response | 30 Days | A strict deadline; failing to reply guarantees a negative reassessment. |
| Notice of Objection (Appeals) | 12 to 24 Months | The Appeals Division has a massive backlog; interest accrues during this time. |
Frequently Asked Questions (FAQ)
Can I pay my 14-year-old child a salary?
Yes, you can legally employ your minor children in Canada. However, the work must be real, necessary for the business, and the pay must be reasonable for their age and skill level (e.g., paying minimum wage for basic filing or cleaning). The CRA scrutinises child wages extremely closely.
What happens if the CRA denies the salary?
If the CRA denies the salary, your corporation loses the tax deduction, meaning corporate taxes increase. Furthermore, the family member who received the money still has to claim it on their personal taxes. This results in severe “double taxation” on the same money.
Do I need to issue a T4 slip to my spouse?
Absolutely. Any salary or wages paid to a family member must be properly documented with a T4 slip filed with the CRA by the end of February each year. Failing to issue a T4 is a major red flag that the “employee” is not legitimate.
Is paying a family member the same as TOSI?
No. The Tax on Split Income (TOSI) rules primarily deal with paying dividends to family members who are shareholders but do not actively work in the business. Paying a legitimate, reasonable salary for actual work performed is an exemption to the TOSI rules.
