Plain-language summary
- Additional CESG is the income-tested top-up on top of the basic Canada Education Savings Grant.
- For 2026, ESDC says the 20% Additional CESG rate applies when adjusted income is $58,523 or less.
- For 2026, the 10% Additional CESG rate applies when adjusted income is more than $58,523 but not more than $117,045.
- The top-up applies only to the first $500 or less of annual RESP contributions for each beneficiary, so the maximum extra amount is usually $100 or $50 for that year.
- Basic CESG is separate: it remains 20% of eligible RESP contributions and is not removed just because income is above the Additional CESG threshold.
- The combined lifetime CESG maximum, including both basic and additional amounts, is still $7,200 per beneficiary.
Action steps
- Estimate the primary caregiver's adjusted income for the contribution year, because the Additional CESG rate is income-tested.
- Check which 2026 bracket applies before assuming the RESP will receive $600, $550, or $500 of CESG for a full $2,500 contribution.
- Contribute at least $500 if you want to capture the full possible Additional CESG for that year, subject to eligibility and provider processing.
- Confirm the child has a SIN, is resident in Canada when the contribution is made, and is named as a beneficiary of the RESP.
- Ask the RESP promoter to apply for both basic CESG and Additional CESG, and ask whether the plan type supports the income-tested top-up.
- If the beneficiary is 16 or 17, confirm the age-16/17 contribution-history rule before relying on any CESG, including the additional amount.
Caveats to watch
- The 2026 thresholds are indexed amounts. Future years may use different thresholds, so do not reuse the 2026 numbers blindly.
- The additional amount is not a second match on every dollar contributed. It only applies to the first $500 of annual contributions.
- A larger contribution can still help earn basic CESG or catch-up CESG, but it does not create more than the annual Additional CESG top-up.
- Income qualification can change from year to year as adjusted income changes.
- The relevant income is tied to the beneficiary's caregiver situation, not necessarily the person who contributes money. This matters when grandparents, relatives, or separated parents contribute.
- Not every promoter or account setup handles every government benefit the same way. Canada.ca says the promoter helps apply for benefits, so families should confirm the application was actually submitted.
Examples
Example: 2026 lower-income bracket
A child qualifies under the 2026 $58,523-or-less adjusted-income bracket. If $500 is contributed, basic CESG would usually add $100 and Additional CESG could add another $100. If $2,500 is contributed and all normal rules are met, the yearly CESG could be $600.
Example: 2026 middle-income bracket
A family has 2026 adjusted income of $90,000. The child may qualify for the 10% additional rate on the first $500 contributed. A $2,500 contribution could receive $500 of basic CESG plus $50 of Additional CESG, for $550 total.
Example: income above the top bracket
A family has 2026 adjusted income above $117,045. The child is not in the Additional CESG bracket for that year, but basic CESG can still apply if the child and contribution meet the normal CESG rules.
How the 2026 brackets work
- $0 to $58,523 of adjusted income: 20% Additional CESG on the first $500 of annual contributions, up to $100 extra.
- More than $58,523 and not more than $117,045: 10% Additional CESG on the first $500 of annual contributions, up to $50 extra.
- More than $117,045: no Additional CESG for that year, but basic CESG can still apply.
- ESDC's 2026 notice says Basic CESG calculations are unchanged at 20% of RESP contributions per beneficiary per year.
Questions to ask your provider
- Did you apply for Additional CESG, or only basic CESG?
- Whose caregiver income information will be used for this beneficiary?
- Does this RESP plan type support Additional CESG in the same way it supports basic CESG?
- If multiple people contribute, how will you track the child's annual CESG room and lifetime $7,200 limit?
- When should I expect the grant deposit, and how will the statement label the basic and additional amounts?
