Few things are more stressful for a small business owner than receiving a letter from the Canada Revenue Agency announcing a review or audit. While some audits are random, many are triggered by specific patterns in your tax returns that attract CRA attention. Understanding what those triggers are — and keeping your books clean — is the best defence.
How the CRA Selects Files for Audit
The CRA uses a combination of methods to identify files for review:
Computer-assisted audit selection. The CRA’s computer systems analyze tax return data and flag returns that deviate significantly from statistical norms for similar businesses in the same industry. If your gross margin is far lower than comparable businesses in Vancouver, or your expense ratios are unusual, it can trigger a flag.
Third-party information matching. The CRA receives T4s, T5s, T3s, T4As, and other information slips from employers, financial institutions, and other sources. When the income reported on your return doesn’t match, the CRA investigates.
GST/HST mismatches. Your GST return reports total sales. If your income tax return reports different sales figures, the CRA notices.
Tips and informants. The CRA has a formal program for receiving tips from the public about potential non-compliance. Disgruntled ex-employees, business partners, and even competitors occasionally report businesses they believe are underreporting income.
Industry-specific programs. The CRA periodically targets specific industries for compliance projects. Cash-intensive businesses — restaurants, contractors, retail — are regularly reviewed.
Random selection. A portion of audits are genuinely random, with no triggering factor.
Common CRA Audit Triggers for Small Businesses
1. Large or Unusual Deductions Relative to Income
If your expenses represent an unusually high percentage of your revenue — especially for home office, meals and entertainment, or vehicle expenses — the CRA may want to verify the business purpose. A consultant reporting 80% of income as home office expenses is unusual. Document everything.
2. Consistent Business Losses
The CRA expects businesses to be profitable. Reporting consistent losses (especially if you also have employment income) raises the question of whether the activity is genuinely a business or a personal hobby. After three consecutive loss years, the CRA may challenge whether you have a “reasonable expectation of profit.”
3. Unreported Income
The CRA uses net worth audits to detect unreported income — comparing your reported income to your lifestyle (home purchases, car upgrades, vacations, assets) and personal expenditures. If your lifestyle significantly exceeds your reported income, expect scrutiny.
Cash-based businesses are especially vulnerable. Restaurant owners, contractors, and retailers who receive cash payments should be meticulous about recording every dollar of revenue.
4. GST/HST Discrepancies
If your GST return and income tax return report different sales figures — even for legitimate timing reasons — the CRA may flag your file. Keep your GST returns and income tax returns consistent, and be prepared to explain any differences.
Large Input Tax Credit (ITC) claims relative to the size of your business, or ITCs in categories that seem unusual for your industry, can also trigger a review.
5. Shareholder Loan Issues
Corporations where the shareholder loan account is in a persistent debit position (meaning the owner has taken more from the corporation than they’ve put in, and hasn’t repaid it within the required time) attract CRA attention. Shareholder loans that aren’t repaid or formalized as salary or dividends within the required period must be included in the shareholder’s personal income.
6. Payroll Discrepancies
If payroll remittances don’t align with T4s filed, or T4s issued to employees don’t match the employment income employees report on their personal returns, the CRA’s matching systems will catch it.
7. Claiming 100% Business Use of a Vehicle
The CRA is skeptical of 100% business-use vehicle claims, particularly for owner-operators who use the same vehicle for personal errands. Without a detailed mileage log, this claim is hard to support. Even if the vehicle genuinely is used only for business, the lack of a mileage log can result in a disallowance.
8. Employees Claiming to Be Contractors
If you engage workers who behave like employees (you control their hours, tools, and methods) but classify them as independent contractors to avoid CPP, EI, and tax withholding, the CRA can reclassify them. This results in back-payment of CPP contributions, EI premiums, and payroll tax for potentially several years — plus penalties and interest.
9. Claiming Personal Expenses as Business Expenses
Home renovations, family vacations, personal meals, children’s clothing, and pets don’t qualify as business expenses. Many CRA audits begin when an auditor reviews expenses and finds a pattern of personal items charged to the business.
10. Cryptocurrency Transactions
The CRA treats cryptocurrency as a commodity, not currency. Gains from selling, trading, or using crypto to buy goods or services are taxable (as either capital gains or business income, depending on your activity). Unreported crypto gains are increasingly a focus of CRA enforcement.
What Happens During a CRA Audit?
If selected, you’ll typically receive a letter requesting information. There are three main types of reviews:
Correspondence review: The CRA asks for documentation supporting specific claims. You respond by mail or through My Account. These are the most common and least invasive.
Desk audit: A CRA auditor reviews your file remotely and may request documents through My Account or by phone.
Field audit: An auditor visits your place of business (or your accountant’s office) to review books and records in person. These are more thorough and typically reserved for more complex files.
How to Reduce Your Audit Risk
Keep meticulous records. For every deduction you claim, have the receipt, the business purpose, and if applicable, the names of others involved (for meals and entertainment).
Maintain a mileage log. If you claim vehicle expenses, keep a contemporaneous mileage log tracking every business trip.
Reconcile your GST and income tax returns. Before filing, confirm that total sales on your GST return matches income on your T2 or T1.
File on time. Late filers are more likely to be flagged.
Use a professional. Returns prepared by professional accountants tend to be more accurate and internally consistent. The CRA knows this, too.
Don’t be aggressive. Some deductions are grey areas. If you’re not certain something qualifies, get advice before claiming it rather than claiming it and hoping for the best.
What to Do if You Receive a CRA Letter
Don’t panic, but don’t ignore it either. Steps to take:
- Read the letter carefully. Is it a request for information, a proposal to reassess, or a notice of assessment?
- Call your accountant or bookkeeper immediately. They’ve dealt with CRA requests before.
- Gather the requested documentation. Organize receipts, bank statements, and records related to the period under review.
- Respond within the deadline. The letter will specify a response deadline. Missing it can result in the CRA reassessing your return without your input.
- Be cooperative but not over-forthcoming. Answer what is asked. You don’t need to volunteer information beyond what the CRA has requested.
If the CRA proposes a reassessment you disagree with, you have the right to file a Notice of Objection within 90 days of the reassessment date. Your accountant can guide you through this process.
Working With a Vancouver Bookkeeper to Stay CRA-Ready
The best time to prepare for an audit is before one happens. When your books are organized, every expense is documented, and your GST returns match your income tax returns, a CRA review is manageable rather than catastrophic.
