InfoCapsule 17: Assistance holdback amount (AHA)

Disclaimer: RDSP issuers

The information contained on this page is technical in nature and is intended for Registered Disability Savings Plan (RDSP), Canada Disability Savings Grant (CDSG) and Canada Disability Savings Bond (CDSB) issuers. For general information, visit the RDSP section.

Consult this page frequently for newer versions. The following laws and regulations take precedence over information contained in InfoCapsules in the event of discrepancies:

  • Income Tax Act
  • Canada Disability Savings Act
  • Canada Disability Savings Regulations


The Assistance holdback amount (AHA)is the total amount of Canada Disability Savings Grant (CDSG) and Canada Disability Savings Bond (CDSB) paid into a Registered Disability Savings Plan (RDSP) within a 10-year period before an event; less any amount of CDSG and CDSB paid into the RDSP during the same 10-year period that has been previously repaid to the Government of Canada.

The CDSG and CDSB paid in a 10-year period, minus any CDSG and CDSB already repaid within that same 10-year period, equals the AHA.

When an event occurs, the AHA is subject to repayment. An event can be:

  • the loss of Disability Tax Credit (DTC) eligibility of the beneficiary
  • the death of the beneficiary
  • the closure of the RDSP
  • the non-compliance of the RDSP
  • a withdrawal: disability assistance payment (DAP) and/or lifetime disability assistance payment (LDAP)

Exception: In the event of a withdrawal, there is no repayment of the AHA if an RDSP is designated as a Specified Disability Savings Plan (SDSP).

The AHA period moves forward in time with the RDSP
