TFSA Overcontribution Penalty 2026: 1% Per Month + Form T1-OVP

The TFSA overcontribution penalty under Income Tax Act §207.02 is the most common Canadian self-directed-investing mistake. Unlike RRSP overcontributions (which have a $2,000 buffer and 1% per month afterward), the TFSA has no buffer: every dollar over your contribution room is charged 1% per month for every month the excess remains in the account.

The penalty is calculated on the highest excess during each calendar month — even a one-day overage triggers a full month’s 1%. For an excess that goes unreported and uncorrected for a year, the cumulative penalty is 12% of the excess — eroding most of the tax-free growth that the TFSA was supposed to provide.

This guide explains the calculation mechanics, the T1-OVP and RC243 filing requirements, the reasonable-cause waiver path, and the practical scenarios that trigger the penalty unintentionally.

For room mechanics see TFSA Contribution Room 2026 Canada. For the same-year-recontribution trap that often triggers this penalty see TFSA Withdrawal Rules.

1. The 1% per month formula

For each calendar month, the penalty is:

Penalty = 1% × Highest amount of excess during the month

The “highest amount of excess during the month” is calculated as follows:

Excess = (Total TFSA contributions to date in current year + Prior years’ unused room used) − (Allowed contribution room as of that date)

The excess is tested daily during the month, and the highest excess in the month is used for that month’s 1%. If the excess is fully withdrawn before the end of the month, the penalty still applies for that month based on the peak excess — but the penalty stops for the next month.

Worked example: 3-month overcontribution

Maria has $0 of contribution room on 1 March 2026 (she had used her entire $7,500 for 2026 plus all prior years’ carry-forward).

• 5 March 2026: Maria deposits $5,000 into her TFSA, thinking she has room.
• 25 March 2026: Maria realizes her mistake and withdraws the $5,000.
• 1 May 2026: She wants to be safe. No more contributions in 2026.

Penalty calculation:

• March: Peak excess during March = $5,000 (was at this level for 20 days). Penalty: $50.
• April: Excess at any point during April = $0 (she withdrew on 25 March). Penalty: $0.
• May+: $0. Penalty: $0.

Total penalty: $50. Form T1-OVP (Individual Tax Return for RRSP, PRPP and SPP Excess Contributions) due by 30 June 2027 for the 2026 tax year. Failure to file the form triggers a separate late-filing penalty.

If Maria had not noticed until December 2026:

• March-December (10 months): $5,000 × 1% × 10 = $500 penalty.

The delay cost $450 of additional penalty over and above the corrective action.

2. Who tracks the room — bank vs CRA vs you

Three parties have a stake in your TFSA contribution room, but only one has authoritative numbers:

Party	Knows…	Lag
CRA My Account	All contributions and withdrawals as of last year-end	Up to 18 months stale
Your bank/brokerage	This account’s contributions and withdrawals only	Real-time for this account
You	All of your TFSA activity across all banks/brokers	Real-time if you keep records

The CRA is always the authoritative source. But CRA data is reported by institutions in February of the following year, and your CRA My Account is updated based on those reports, usually by late spring. So:

• A 2026 contribution made in March 2026 will not appear in your CRA My Account until ~June 2027.
• Your 2026 contribution room as displayed in CRA My Account in June 2026 reflects your 2025 year-end position.

Most overcontributions happen because the user relies on stale CRA data. Always combine CRA data with your real-time bank/brokerage statements to derive current actual room.

The multi-institution trap

If you have TFSAs at more than one bank or brokerage, the CRA aggregates all your TFSAs into one contribution-room calculation. But each bank only sees its own account.

• Bank A’s online system shows: “$5,000 contribution room available” (for THIS TFSA).
• Bank B’s online system shows: “$3,000 contribution room available” (for THAT TFSA).

You might think you have $5,000 + $3,000 = $8,000 of room across two accounts. Actually, the CRA’s $7,500 annual limit (or however much you have total) is the only limit that matters — and the two banks don’t share data with each other. If you contribute $5,000 to Bank A and $3,000 to Bank B, you’ve contributed $8,000 across both, which may exceed your actual aggregate room.

The CRA discovers this when both banks report their 2026 contributions in February 2027, and your June 2027 review of CRA My Account shows a $500 excess for the 2026 tax year. By then, you’ve been over-contributed for 9-12 months. The penalty is 9-12 × $5 = $45-$60.

3. Filing requirements when over-contributed

Form T1-OVP — within 90 days of year-end

If you have any TFSA excess contribution outstanding for more than 1 day during the year, you must file Form T1-OVP (Individual Tax Return for RRSP, PRPP and SPP Excess Contributions) within 90 days of year-end — i.e., by 31 March of the following year for a regular tax year.

The form is filed with the CRA, calculating the monthly penalty for each month the excess was outstanding. Late filing triggers a separate late-filing penalty.

Form RC243-SCH-A — annual

Form RC243-SCH-A (Schedule A) is the annual schedule reconciling all TFSA contributions to your contribution room. This is required regardless of whether you over-contributed — it’s part of your individual T1 return for the year.

Penalty payment

The 1% per month penalty is added to your individual tax liability for the year of the excess. It is NOT a separate payment to the TFSA itself. The TFSA balance is unaffected by the penalty; the penalty is paid out of your personal funds at the same time you file your T1.

4. Reasonable-cause waiver — when CRA forgives

The CRA has discretion under §207.06 to waive the 1% penalty if the excess was:

1. The result of a reasonable error (typically: relying on incorrect CRA My Account data, misunderstanding the recontribution-delay rule, or a financial institution providing wrong information).
2. Promptly corrected (the excess was withdrawn as soon as you became aware).

The waiver is requested by writing a letter to the CRA explaining the circumstances and attaching evidence (bank statements showing the contribution, CRA My Account screenshot showing the stale room data, the withdrawal confirmation). Typical CRA response time: 3-6 months.

Waiver success rates (from CRA enforcement statistics, broadly):

• First-time over-contributors with stale CRA data: Most granted.
• Multi-institution mistakes: Often granted with documentation.
• Repeated over-contributions: Generally denied.
• Aggressive over-contribution strategy (e.g., contributing in anticipation of future room): Always denied.

The waiver does not reverse the penalty assessment — the CRA grants it as a separate decision after you’ve paid the penalty. The refund is then issued.

5. Common scenarios that trigger the penalty

5.1 Same-year recontribution after a withdrawal (most common)

Covered in detail in TFSA Withdrawal Rules. The withdrawal restores room only on 1 January of the next year. Recontributing in the same year is the most common path to a 1% penalty.

5.2 Forgetting to check CRA My Account before contributing

A March 2026 review of CRA My Account shows room “as of December 2025”. A contributor who used $5,000 of room in 2025 (uncaptured in the March 2026 CRA display) over-contributes by that $5,000.

5.3 Multi-institution contributions

Contributing to TFSAs at multiple banks/brokerages without aggregating. Each bank reports independently, but the limit is aggregated. See section 2 above.

5.4 Transferring TFSAs incorrectly

A “withdraw from Bank A, deposit to Bank B” sequence in the same year is treated as a withdrawal-plus-contribution, not a transfer. If you want to move TFSA funds between institutions, use Form RC213 (direct trustee-to-trustee transfer) — this preserves the tax-free treatment without affecting room.

5.5 Spouse’s contribution from a joint account

A contribution to your TFSA from a joint chequing account is treated as your contribution, regardless of which spouse the money technically came from. If your spouse intended to fund their own TFSA, they need to make the contribution from their TFSA’s funding source — typically their own personal chequing account.

5.6 New immigrants over-contributing in their landing year

A new immigrant landing in Canada in 2026 accrues only the 2026 annual room of $7,500. If they bring savings from abroad and try to “catch up” by contributing $50,000 (thinking they should match a long-term Canadian resident), they over-contribute by $42,500. Penalty: $425 per month for as long as the excess remains.

6. Special case: non-resident TFSA contributions

If you become a non-resident of Canada and continue to make TFSA contributions while non-resident, those contributions are subject to a special 1% per month non-resident contribution penalty (separate from the regular over-contribution penalty). Even if you have room, you cannot use it during non-residency.

For dual-citizen U.S. persons resident in Canada: the TFSA is treated as a foreign grantor trust by the IRS, which requires annual filing of Forms 3520 and 3520-A. This is a separate IRS compliance burden but does not affect the Canadian rules.

7. Avoiding the penalty — checklist

Before every TFSA contribution:

• Check CRA My Account for your current room (note the data lag).
• Add 2026 contributions made YTD to your room calculation.
• Subtract any 2026 withdrawals that have NOT yet rolled over to next year’s room.
• If multiple institutions, sum all TFSAs in the calculation.
• Leave a buffer of $500-1,000 to account for institution-level rounding or pending settlements.

If you discover an over-contribution:

• Withdraw the excess immediately (each additional month is another 1%).
• File Form T1-OVP by 31 March of the next year.
• If first-time error, write the CRA a waiver request with supporting documentation.
• Update your tracking spreadsheet to avoid repeat occurrences.
