Alternate format


Issuers send monthly transactions to Employment and Social Development Canada (ESDC). The Canada Disability Savings Program (CDSP) system will either process or reject these transactions based on format and validation rules.

Rejected transaction

  • The issuer will be advised through either the error file (RT 801) or the severe error file (RT 851)
  • A 4-digit error code will be generated

Error code Description Resolution
(see Appendix A of the RDSP provider user guide)
8102 Is not identified in the CDSP system

Review the transaction and ensure that the data corresponds to data previously validated by the CDSP system for the concerned RDSP.

The following data fields should be verified for accuracy: issuer business number (BN), specimen plan, holder and beneficiary Social Insurance Number (SIN) information and contract number.

8105 Invalid SIN Ensure that the SIN data is correct and matches the information provided by the client. If so, refer the client to the Social Insurance Register to verify what information they have on file.
8201 Date is of a future reporting period Ensure the date provided is on or before the current reporting period end date set by the CDSP system.
8235 Contract is not currently associated to the specimen plan Ensure there are no errors in the specimen plan submitted to the CDSP system, and that the contract was not already submitted.
8236 Contract is not currently associated to the beneficiary Verify the contract number and beneficiary SIN data submitted to the CDSP system.

Processed transactions

  • The issuer will be advised through the transaction processing file (RT 901)
  • Although a transaction is successfully processed, full or partial payment of the Canada Disability Savings Grant (CDSG) or the Canada Disability Savings Bond (CDSB) may be denied; in which case, a refusal reason (2-digit code) will be generated

Table of the most common refusal reasons and their proposed resolutions

Refusal reason Description Resolution (see Appendix B of the RDSP provider user guide)
01 Maximum current entitlement of CDSG and CDSB paid Generally no action is required.
04 Age of beneficiary No action is required as the CDSG and the CDSB will not be paid after the end of the year in which the beneficiary turned 49 years of age.
06 No grant requested If the CDSG was to be requested for the contribution, submit a contribution correction transaction for the same amount as the original contribution, and ensure the flag is set to Yes.
19 Contract not registered Consult the contract status file to determine why the contract is not registered and re-submit all three 101 transactions. Once all three transactions of the contract registration package are processed successfully, re-submit any rejected CDSG and CDSB request transaction(s).
30 Beneficiary DTC eligibility not confirmed Refer the holder to the CRA to confirm DTC.
