this i the latest communication that we received from CRA:
Safeguards to protect taxpayer information
The Canada Revenue Agency (CRA) takes the protection, privacy and security of Canadians’ information very seriously.
As the CRA continues to invest in security and enhance its technologies, processes and controls, additional identification validations have been put in place for the 2024 filing season (2023 tax year).
First-time filer validations
First-time filer validations have been enhanced for EFILE for the 2023 tax year. Taxpayer’s identity information such as first name (given name), if applicable, middle name (second name), if applicable, last name (family name) and date of birth must be an exact match to the identification information as issued under their social insurance number for the return to be accepted and for the taxpayer’s identification information to be updated on CRA records.
For first-time filer individuals with one name only, tax preparers may add the name in the last name (family name) field and leave the other name fields blank.
For any unsuccessful transmission, new response message 110-B will be returned. Please verify your client’s identity information – first name (given name), if applicable, middle name (second name), if applicable, last name (family name) and date of birth. Should the error persist following unsuccessful attempts, we recommend filing the 2023 Income Tax and Benefit Return in paper form.
