The Tax-Free Savings Account (TFSA) is one of Canada’s most beneficial investment tools, allowing Canadians to grow their savings tax-free. But despite its simplicity, the Canada Revenue Agency (CRA) keeps a close eye on how these accounts are used. Misuse or misunderstanding of TFSA rules can lead to CRA audits, penalties, or even taxes on what was supposed to be tax-free income.

If you’re not careful, you could raise one of several CRA TFSA red flags—and that could cost you. Here’s a detailed look at the most common red flags and how to avoid them.
1. Overcontributing to Your TFSA
Each Canadian has an annual TFSA contribution limit—in 2025, it’s $7,000. If you exceed your available contribution room, you’ll face a 1% monthly tax on the excess amount, continuing until the issue is resolved.
How to Avoid:
- Check your TFSA room via your CRA My Account.
- Remember: Withdrawals made this year increase your contribution room next year, not immediately.
- Track contributions across multiple accounts to avoid accidental overcontributions.
2. Frequent or High-Volume Trading
The TFSA is intended for passive investing. If you’re actively trading like a day trader within your TFSA, the CRA may consider that you’re carrying on a business—and tax your income accordingly.
Red Flags for CRA:
- Rapid buy-and-sell transactions
- Short holding periods
- Use of leverage (borrowing money to invest)
- Repeating patterns of speculative behavior
How to Avoid:
- Focus on long-term investments like ETFs or mutual funds.
- Keep trading frequency low.
- Maintain proper records that support your investment strategy as non-business in nature.

3. Contributing While a Non-Resident
Only Canadian residents for tax purposes are allowed to contribute to a TFSA. If you become a non-resident and continue contributing, you’ll face a 1% monthly penalty on those contributions.
How to Avoid:
- Stop TFSA contributions if you move abroad.
- Inform the CRA of changes to your residency status.
- Check your eligibility each year before making a contribution.
4. Unusually High or Rapid Account Growth
Significant gains in a TFSA may trigger an audit—especially if the growth seems disproportionate to the investments or time horizon. The CRA may assess whether the gains resulted from business activities, which are not tax-exempt under TFSA rules.
How to Avoid:
- Avoid using insider knowledge or speculative bets.
- Make sure growth can be explained by standard market performance.
- Keep documentation to support how gains were achieved.

5. Delayed Correction of Overcontributions
If you realize you’ve overcontributed, acting quickly is essential. Waiting too long to withdraw the excess can lead to ongoing monthly penalties and make it appear deliberate.
How to Avoid:
- Review your CRA contribution history regularly.
- Withdraw any excess contributions as soon as possible.
- Respond quickly if the CRA contacts you about your TFSA.
6. Misunderstanding Withdrawal Rules
A common misconception is that you can recontribute withdrawn amounts in the same year. In reality, the amount you withdraw is added back to your contribution room only in the next calendar year.
How to Avoid:
- Plan withdrawals and re-contributions carefully.
- If in doubt, wait until the following year to recontribute.
- Keep your own detailed TFSA ledger, not just your bank statements.
7. Using TFSA for Business Purposes
The TFSA is not a business account. If you’re using it to conduct business-like activities—such as flipping properties, short-term stock speculation, or operating a business—the CRA can assess tax on your TFSA income.
How to Avoid:
- Don’t use the TFSA to fund or operate a business.
- Avoid treating it like a high-frequency trading account.
- Stick to investments consistent with passive income generation.
Final Thoughts: Avoiding CRA TFSA Red Flags Is Easier Than You Think
The TFSA is a powerful tool for building wealth, but it’s not a loophole or a business shelter. By staying within the rules and avoiding the CRA TFSA red flags outlined above, you can safely take advantage of your account’s tax-free growth potential.
Educate yourself, track your activity, and stay compliant—so your TFSA remains an asset, not a liability.
