Accidentally overcontributing to an RRSP results in a 1% monthly tax penalty on amounts exceeding your limit by more than $2,000. While a $2,000 buffer exists, excess amounts above this are taxed until withdrawn or covered by new room. To fix this, withdraw the funds, file Form T1-OVP to pay the penalty, or request a waiver for reasonable errors.
First, you will want to file your T1-OVP form and pay the 1% penalty within the first 90 days of the following calendar year. This will help you avoid any late filing penalties. Once you pay the 1% penalty and complete the appropriate forms, your over-contribution then rolls into next year's deduction limit.
You will pay a 1% penalty per month on the excess contribution amount. The penalty is calculated based on the highest excess amount during the month.
To stop the penalty tax from accruing, you need to either withdraw the excess amount from your TFSA or receive new contribution room to absorb the over-contribution, which occurs on January 1 of the following year.

Traditional and Roth Excess Contribution Removal Deadline
The removal deadline for excess contributions to a traditional IRA or a Roth IRA is your tax-filing deadline. This is typically April 15 of the following year (or October 15 if you're filing an extension).
The IRS finds out about Roth IRA overcontributions primarily through Form 5498, which your financial institution sends to you and the IRS showing your contributions, and by cross-referencing your tax return (Form 1040) with your income and filing status, sometimes catching errors years later when processing these forms. They also use Form 1099-R if you withdraw an excess amount, and your tax software (like TurboTax) might flag it as you file.
If you overcontribute to a 401(k), the excess amount becomes taxable income in the year it was contributed and can be taxed again when distributed in retirement, leading to double taxation, unless you correct it by the tax filing deadline (April 15th of the following year) by removing the excess funds and any earnings. Correcting it involves notifying your plan administrator to get a "corrective distribution" of the excess and earnings, which is then reported on your W-2 and tax return to avoid the second tax hit.
The five key mistakes to avoid in a TFSA are over-contributing (and re-depositing withdrawals in the same year), treating it like a basic savings account (missing out on investment growth), failing to track your room (relying solely on CRA data), improperly moving funds (withdrawing and redepositing instead of transferring), and investing in non-qualified assets or high-risk trades (like day trading or certain foreign stocks that incur withholding tax).
The attribution rule.
If the spouse who owns the RRSP (the annuitant) withdraws funds within 3 years of the last contribution, the Canada Revenue Agency (CRA) will attribute that withdrawal back to the contributing spouse, meaning the contributor will pay the tax on the withdrawn amount.
Excess contributions are taxed at 6% per year for each year the excess amounts remain in the IRA. The tax can't be more than 6% of the combined value of all your IRAs as of the end of the tax year.
What Happens If You Over-Contribute to Your RRSP? The CRA allows a $2,000 grace amount for RRSP over-contributions. If you exceed your limit by less than $2,000, no tax will be assessed. However, if your over-contribution exceeds $2,000, you will be subject to a tax of 1% per month on the excess amount.
At any time in the year, if you contribute more than your available TFSA contribution room you will have to pay a tax equal to 1% of the highest excess TFSA amount in the month, for each month that the excess amount stays in your account.
— Total Wealth Planning, Scotia Capital Inc. Your RRSP is the key to beating inflation, saving taxes and ensuring a financially healthy retirement. However, unless you maximize your RRSP contributions every year, you will likely cheat yourself out of significant benefits at retirement.
Contributions can be deducted from taxable income when filing your tax return, meaning you can end up paying less taxes and saving more money. You may get anywhere from 20 per cent to 50 per cent of your RRSP contributions back as an income tax refund based on your marginal tax rate.
Here are four you should consider.
Roughly 7% to 9% of American households have $500,000 or more in retirement savings, though figures vary slightly by source, with data from late 2025 suggesting around 7.2% and older 2022 data indicating about 9%, showing it's a significant milestone achieved by less than one in ten families, despite higher averages driven by wealthy individuals.
Generally, you have to pay a tax of 1% per month on your unused contributions that exceed your RRSP deduction limit by more than $2,000.
Contributions for all types of IRAs—Roth, traditional, SEP, and SIMPLE—are reported on Form 5498.
Roth IRA contributions do not go anywhere on the tax return so they often are not tracked. The exceptions are on the monthly Roth IRA account statements or on the annual tax reporting Form 5498, IRA Contribution Information.
