7 CRA Red Flags That Trigger Corporate Tax Audits (And How to Avoid Them)

Corporate tax audits don’t happen randomly. In most cases, the CRA flags specific patterns on T2 corporate tax returns that indicate higher risk. If you own an incorporated business in Ontario, understanding these red flags can significantly reduce your audit exposure.

At Podolsky Accounting, we regularly assist corporations facing CRA reviews and audits — and the same issues appear repeatedly.

1. Shareholder Loan Accounts That Don’t Make Sense

One of the most common CRA audit triggers is an improperly reported shareholder loan balance. Overdrawn or uncleared shareholder loans can quickly lead to reassessments and taxable benefits.

CRA often focuses on:

• Large year-end shareholder loan balances
• Loans not repaid within the required time frame
• Missing documentation or inconsistent reporting

2. High Expenses Relative to Revenue

Corporations reporting unusually high expenses compared to revenue frequently trigger CRA reviews. This is especially common in owner-managed small businesses.

CRA pays close attention to:

• Vehicle and home office expenses
• Meals and entertainment
• Personal expenses run through the corporation

3. Inconsistent HST and T2 Reporting

If your HST filings don’t align with your T2 corporate tax return, the CRA’s systems will notice. HST mismatches are one of the fastest ways to trigger a desk audit.

This often happens when bookkeeping and tax filing are handled separately without professional review.

4. Repeated Losses Year After Year

Corporations that report losses consistently may be flagged to determine whether the business is truly commercial or partially personal in nature.

CRA may question:

• Business intent and profitability
• Expense deductibility
• Whether the corporation is being used for tax deferral only

5. Late or Missing T2 Filings

Even inactive corporations must file a T2 return. Repeated late filings or missing returns significantly increase audit and penalty risk.

Professional corporate tax return services help prevent these issues entirely.

6. Aggressive Salary vs Dividend Splits

Improper compensation planning can raise CRA concerns, especially when dividends or salaries fluctuate without clear reasoning.

A CPA ensures compensation strategies are tax-efficient and defensible.

7. DIY Corporate Tax Filings

Self-prepared T2 returns often contain technical errors that trigger CRA follow-up. Unlike personal returns, corporate filings involve complex schedules that CRA reviews carefully.
