Quick Answer
If you over-contribute to a Registered Education Savings Plan (RESP), the excess amount may be subject to a 1% monthly tax until it is withdrawn. The $50,000 lifetime contribution limit applies per beneficiary across all RESPs, but government grants, eligible provincial benefits, and investment earnings are not counted as contributions for this limit.
Main Takeaways
- The $50,000 RESP lifetime contribution limit is per beneficiary — not per account.
- Multiple subscribers can accidentally exceed the limit together without knowing it.
- Excess contributions may face a 1% monthly tax for as long as they remain in the plan.
- Government grants like the CESG and eligible provincial benefits do not count toward the $50,000 limit.
- Withdrawing the excess can reduce ongoing penalty exposure but does not erase contribution history.
- Families should keep contribution records across every RESP opened for the same child.
Finding out you may have over-contributed to an RESP can feel stressful. The good news is that once you understand what happened, there are clear steps you can take. At Embark, we help families work through exactly this kind of situation, and with the right steps, most cases are manageable.
Below, we cover what the RESP over-contribution penalty means, what counts toward the limit, how grants are treated, and the steps to take if you need to fix things.
What is an RESP over-contribution?
An RESP over-contribution happens when total contributions made by all subscribers to all RESPs for one beneficiary (the child the RESP is for) exceed the lifetime contribution limit.
In Canada, the lifetime RESP contribution limit is $50,000 per beneficiary. This limit applies across every RESP opened for the same child — not just one account. If a child has two RESPs, the combined contributions to both plans must stay under $50,000.
It’s a common situation for families where parents and grandparents open separate plans without coordinating contributions. For a deeper look at how the limit works, see our article on RESP contribution limits.
What counts toward the RESP contribution limit?
Not everything that goes into an RESP counts as a contribution. The table below shows what does and what does not.
| Item | Counts toward the $50,000 limit? |
|---|---|
| Your contributions as a subscriber | Yes |
| Contributions from grandparents or other family members | Yes |
| Contributions to multiple RESPs for the same child | Yes |
| Canada Education Savings Grant (CESG) | No |
| Canada Learning Bond (CLB) | No |
| Eligible provincial benefits (e.g., BCTESG, QESI) | No |
| Investment growth inside the RESP | No |
Only the actual dollar contributions from subscribers count toward the $50,000 limit. Grants, bonds, and investment returns do not.
What is the RESP over-contribution penalty?
The penalty for over-contributing to an RESP is a 1% monthly tax on the excess amount. This tax applies to each subscriber’s share of the excess — meaning if more than one person contributed, the tax is divided based on each person’s share of the over-contribution.
The 1% monthly tax continues for as long as the excess remains in the plan. For example, if the excess amount is $1,000, the penalty works out to roughly $10 per month. That adds up over time, which is why it is important to take action as soon as you identify a potential problem.
The tax is reported and paid by the subscriber — not the plan itself. If you are unsure how to calculate your share or how to report it to the CRA, a tax professional can help.
How do over-contributions affect RESP grants?
Over-contributing does not create extra grant eligibility. Grants like the Canada Education Savings Grant (CESG) are based on eligible contributions, and excess contributions do not qualify for additional CESG.
Government grants and eligible provincial benefits also do not count toward the $50,000 lifetime limit. You do not need to include CESG or Canada Learning Bond amounts when determining whether you have exceeded the limit.
The risk is that over-contributing leads to a monthly tax penalty without any additional benefit. You take on the ongoing 1% cost, but you do not receive extra grant money in return.
How to fix an RESP over-contribution
If you think you may have over-contributed, here are the steps to take:
- Collect your plan statements. Gather contribution records from every RESP opened for the beneficiary — not just your own account.
- Confirm the total contributions. Add up all contributions from all subscribers across all plans. Remember: only subscriber contributions count, not grants or investment growth.
- Identify who contributed and when. Knowing each subscriber’s share of contributions helps determine how the penalty is divided.
- Contact your RESP provider. Your provider can confirm the contribution history in their plan and help you understand next steps.
- Withdraw the excess if appropriate. Withdrawing the excess can stop the ongoing 1% monthly penalty going forward. Note that withdrawn contributions still count toward your lifetime contribution history — withdrawing does not erase past contributions from the record.
- Review CRA reporting requirements. You will likely need to file Form T1E-OVP with the CRA to report and pay the tax on excess contributions. Speak with a tax professional or contact the CRA directly to confirm the requirements for your situation.
- Keep records. Save all statements, withdrawal confirmations, and any CRA correspondence for future reference.

What if multiple people contributed to the same child’s RESPs?
This is one of the most common reasons for RESP over-contributions. Parents open one plan, grandparents open another, and no one keeps a shared record. Before long, the combined contributions for the same child have crossed $50,000 without anyone realizing it.
If this has happened in your family, the most important step is to gather contribution records from every plan. The limit belongs to the beneficiary — not to any individual subscriber or plan holder. Everyone who contributed needs to know the full picture. If you’re not sure where the total stands, Embark’s digital platform makes it easy to keep track of how much you’ve contributed and what types of funds their RESP is comprised of.
Going forward, use one shared method to track contributions across all plans. Even a simple shared spreadsheet with each subscriber’s contributions and a running total can prevent a repeat. Our article on whether a child can have more than one RESP explains how multiple accounts interact.
How to prevent RESP over-contributions
A few simple habits can help families avoid going over the limit:
- Track lifetime contributions across all plans. Don’t rely on memory — keep a written record that all subscribers can access and reference.
- Coordinate with other subscribers. If grandparents, aunts, or uncles want to contribute, let them know the current total before they add to the plan.
- Check contribution room before making large gifts. A lump-sum contribution is a generous gesture — just make sure there is room. See our guide on RESP maximum contributions.
- Use annual reviews. Build a habit of reviewing total contributions each year, especially when there are multiple RESPs for the same child.
- Be careful with catch-up contributions. A large catch-up contribution without verifying remaining room can push a plan over the limit.
For more, see our articles on RESP maximum contributions and RESP catch-up contributions.
Common mistakes to avoid
Counting grants as contributions.
Grants like the CESG are added by the government and do not count toward the $50,000 limit. You only need to track the contributions you and other subscribers make directly.
Assuming each RESP has its own $50,000 limit.
The limit belongs to the beneficiary, not the account. If a child has two RESPs, the combined total from both plans cannot exceed $50,000.
Forgetting grandparent or family RESPs.
A well-meaning relative may have opened a separate plan years ago. It’s worth checking whether another RESP exists before making a large contribution.
Making a large lump sum without checking history.
A one-time catch-up contribution can push a plan over the limit if the remaining room has not been verified first.

Frequently Asked Questions
What is the RESP over-contribution penalty?
The penalty is a 1% monthly tax on the subscriber’s share of the excess contribution amount. It continues until the excess is withdrawn from the plan.
How do I fix an RESP over-contribution?
Gather contribution records from all RESPs for the beneficiary, contact your RESP provider, withdraw the excess if appropriate, and confirm whether CRA reporting is required. Consider speaking with a tax professional for guidance specific to your situation.
Do RESP grants count toward the $50,000 limit?
No. Government grants like the CESG and Canada Learning Bond, as well as eligible provincial benefits, are not counted as contributions for the purpose of the lifetime contribution limit.
Can more than one RESP cause an over-contribution?
Yes. The $50,000 lifetime limit applies per beneficiary across all RESPs. If a child has two or more plans, the total contributions from all plans combined must stay under $50,000.
Does withdrawing the excess remove the penalty?
Withdrawing the excess can stop the ongoing 1% monthly tax from continuing. However, withdrawn contributions still count toward the lifetime contribution history — withdrawing excess contributions does not reset or erase the record of past contributions.
What to Do Next
An RESP over-contribution can happen to any family — especially when more than one person is saving for the same child. The key is to act once you identify the issue. Collect your records, contact your RESP provider, and take the appropriate steps to reduce the ongoing monthly penalty.
