RESP beneficiary changes simplified

Plain-language summary

• You can add another child only to a family RESP. The child generally must be related to each living subscriber by blood or adoption and usually must be under age 21 when added, unless they were immediately before a beneficiary of another family RESP.
• To name or replace a beneficiary, the new beneficiary's SIN must be given to the promoter, and the beneficiary generally must be a resident of Canada when designated.
• Changing a beneficiary can move the old beneficiary's contribution history onto the new beneficiary. That can create an RESP over-contribution problem if the new beneficiary already has RESP contributions elsewhere.
• If government grants or bonds are already in the plan, adding a non-sibling beneficiary to a family RESP can trigger repayment of federal or provincial benefits.

Action steps

1. Before changing anything, identify the exact plan type: family, individual, or group. The rules are not identical.
2. Ask the promoter whether you are adding a beneficiary or replacing one, because providers may use different paperwork and the tax effects can differ.
3. Check the new beneficiary's SIN, current Canadian residency status, age, and relationship to the subscriber before submitting the request.
4. Add up RESP contributions already made for the new beneficiary across every RESP, including plans held by parents, grandparents, or a former spouse, before moving old contribution history onto that child.
5. If grants, bonds, or provincial incentives are already in the RESP, ask the promoter exactly which amounts would be repaid under the proposed change before you sign anything.

Caveats to watch

• The broad rule is easy to miss: when you replace one beneficiary with another, CRA generally treats the old contributions as if they had always been made for the new beneficiary.
• Two limited exceptions can prevent that contribution-history carryover for over-contribution testing. One applies when the new beneficiary is under 21 and shares a parent with the former beneficiary. The other applies when both are under 21 and connected by blood relationship or adoption to an original subscriber.
• A family RESP can have more than one beneficiary, but every new contribution still has to be assigned to specific beneficiaries rather than dropped into a shared bucket with no allocation.
• Government benefit repayment and contribution-limit issues are separate risks. A change might avoid one problem while still causing the other.
• Some providers restrict beneficiary changes or require extra review even when the tax rules allow the change.

Examples

Example: adding a younger sibling to a family RESP

A family RESP already exists for one child and has received CESG. The parents add that child's younger sibling, who is related by blood, has a SIN, and is under 21. Canada.ca says a sibling can generally be added without grant repayment, but the family still needs to track how future contributions are allocated between the two children.

Example: replacing a beneficiary can create a hidden over-contribution

An RESP with $20,000 of past contributions for Child A is switched to Child B. Child B already has $35,000 of contributions in another RESP. Unless an exception applies, CRA generally treats the old $20,000 as if it had always been made for Child B, which could push Child B above the $50,000 lifetime RESP contribution limit.

What this means in real life

• Families often think a beneficiary switch is just an admin update. In practice, it can affect grant repayment, lifetime contribution room, and provider processing.
• The highest-risk situations are blended families, multiple RESP providers, grandparents contributing separately, and late changes after grant money has already arrived.
• The safest workflow is to confirm the rule first, then the paperwork, then the dollar impact.

Questions to ask your provider

• Will this be processed as adding a beneficiary or replacing one?
• Would this change force repayment of CESG, CLB, or any provincial incentive?
• Do you see any over-contribution risk once the former beneficiary's contribution history is mapped to the new beneficiary?
• If this is a family plan, how will future contributions be allocated between beneficiaries?
• Do your internal plan terms impose any extra restrictions beyond the government rule?
