Effective January 12, 2026, CRA has retroactively updated its XML specifications for filing previous year XML returns. Consequently, any XML file generated using AvanTax eForms 2024.114 and earlier will probably be rejected by CRA if:
♦ You did not enter a Transmitter Rep ID, meaning that you are using a Transmitter CRA Account Number, which could be either a 15-character business number, a 9-character SIN or a trust identification number.
or
♦ If you are submitting 2024 AGR1, T5 or T5008 Returns, regardless of whether or not you have entered a Transmitter Rep ID.
In these above noted cases CRA will probably reject your XML submission if it was created by eForms 2024.114 and earlier.
AvanTax eForms 2024.115 updates XML processing to comply with the CRA requirements that came into effect on January 12, 2026. Therefore, almost all eForms users who wish to file forms produced by eForms 2024 should download this new release.
We also provide a free utility that can update previous years' XML files to comply with the CRA requirements that came into effect on January 12, 2026. This includes XML files created by all eForms versions released before eForms 2024.115, including eForms 2023 and earlier years.
