Quick Summary

You accidentally contributed too much to your TFSA. Maybe you forgot about a withdrawal earlier in the year, or you miscalculated your contribution room. Now you're wondering: What happens if I over-contribute to my TFSA?

If you over-contribute to your TFSA, the CRA charges a penalty of 1% per month on the excess amount until you withdraw it. On a $5,000 over-contribution, that's $50/month in penalties — and it keeps adding up until you fix it.

Here's exactly what the TFSA over-contribution penalty is, how to calculate it, how to fix it, and how to avoid it in the future.

TFSA Over-Contribution Penalty

1% per month on the highest excess amount in each month. The penalty applies every month until the over-contribution is withdrawn, even if you withdraw it quickly.

What Is the TFSA Over-Contribution Penalty?

The CRA imposes a 1% per month penalty on any amount you contribute over your TFSA contribution limit.

How the Penalty Works

  • 1% per month on the highest excess amount in each month
  • • Penalty applies every month until the over-contribution is withdrawn
  • • You'll receive a Notice of Assessment (Form RC243) from the CRA
  • • You must pay the penalty even if you withdraw the excess immediately

Example: TFSA Over-Contribution Penalty

You have $5,000 in TFSA contribution room. You accidentally contribute $8,000 in January 2026.

  • Over-contribution: $3,000
  • Monthly penalty: $3,000 × 1% = $30/month
  • Total penalty (if you withdraw in March): $30 × 3 months = $90

The penalty applies for the full month, even if you over-contributed on the last day of the month.

How to Check Your TFSA Contribution Room

Before you contribute to your TFSA, you should always check your available contribution room.

Method 1: CRA My Account (Most Accurate)

  1. 1. Log into CRA My Account
  2. 2. Select "TFSA" under "Tax-Free Savings Account"
  3. 3. View your current contribution room

Important: The CRA updates TFSA information based on reports from your financial institutions. Transactions can take 4-6 weeks to appear.

Method 2: Calculate It Yourself

Formula: Current Room = Previous Year's Room + New Annual Limit + Withdrawals - Contributions

Example (2026 calculation):

  • • 2025 unused room: $10,000
  • • 2026 annual limit: $7,000
  • • Withdrawals in 2025: $5,000
  • • Contributions in 2026 (so far): $6,000
  • 2026 contribution room: $16,000

YearAnnual Limit
2009-2012$5,000
2013-2014$5,500
2015$10,000
2016-2018$5,500
2019-2022$6,000
2023$6,500
2024-2026$7,000

Total cumulative limit (2009-2026): $102,000 (if you were 18+ in 2009 and never contributed)

What to Do If You Over-Contributed

If you discover you've over-contributed, follow these steps immediately:

Step 1: Withdraw the Excess Amount ASAP

Contact your TFSA provider and withdraw at least the over-contribution amount.

Timing matters: The penalty applies for the full month, so withdraw ASAP to minimize penalties.

Step 2: Calculate Your Penalty

Figure out how many months you were over-contributed and calculate the 1% monthly penalty on the excess amount.

Step 3: Wait for the CRA's Notice

The CRA will send you a Notice of Assessment (Form RC243) showing your over-contribution and the penalty owed. This usually arrives several months after your over-contribution.

Step 4: Pay the Penalty

Pay by the due date on your RC243 notice through your bank's bill payment system or CRA My Payment. Late payment results in interest charges.

How to Request Penalty Waiver or Cancellation

If your over-contribution was a genuine mistake and you withdrew the excess as soon as you realized, you can ask the CRA to waive or cancel the penalty.

When the CRA May Waive Penalties

  • • You made a reasonable error (e.g., relied on incorrect information)
  • • You withdrew the excess amount as soon as you became aware
  • • You have a history of compliance (no previous over-contributions)
  • • The over-contribution was small and short-lived

How to Request a Waiver

Write a letter to the CRA explaining what happened, why it was a reasonable error, when you discovered and withdrew the over-contribution, and why you believe the penalty should be waived.

Common TFSA Over-Contribution Mistakes

Mistake #1: Not Knowing Withdrawals Don't Give You Room Until Next Year

This is the #1 cause of TFSA over-contributions. When you withdraw from your TFSA, you don't get that contribution room back until January 1 of the following year.

Mistake #2: Not Tracking Contributions Across Multiple TFSAs

Your contribution room is shared across all TFSA accounts. If you have TFSAs at multiple banks, track total contributions manually.

Mistake #3: Trusting Your Bank's "Available Room" Estimate

Banks don't always have up-to-date information about contributions at other institutions. Always verify with the CRA before making large contributions.

TFSA Contribution Room Rules You Need to Know

1. You Accumulate Room Every Year

If you don't contribute in a given year, your unused room carries forward indefinitely. If you turned 18 in 2009 and never contributed, your 2026 room is $102,000.

2. Withdrawals Give You Room Back — But Not Until Next Year

Withdrawals are added to your contribution room on January 1 of the following year. If you withdraw $10,000 in June 2026, you get that room back on January 1, 2027.

3. Investment Gains Don't Count Against Your Room

If your TFSA grows from $50,000 to $80,000 due to investment gains, the $30,000 gain does not reduce your contribution room.
