The Canada Revenue Agency's EFILE, ReFILE and T1135 web services will stop accepting transmissions of your clients' initial and amended (T1) personal income tax and benefit returns and T1135 forms for T1 at 11:59 p.m. on Friday, January 28, 2022, (Eastern Time), in order to convert our systems for the next filing season. These services will re-open on Monday, February 21, 2022, at 8:30 a.m. (Eastern Time). Thank you for your continued support and participation.

Please ensure you transmit any initial or amended T1 returns and T1135 forms for T1 before January 28, 2022, to avoid having to wait until the new program starts.

The following services will still be available after January 28, 2022:

· Corporation Internet Filing for Corporation Income Tax (T2) returns.

Note: You must have renewed your EFILE account, passed suitability screening and updated your tax preparation software with your newly assigned password to continue to file T2 returns using your EFILE number and password after January 28, 2022. Go to canada.ca/revenue-agency/corporation-internet

· Electronic filing of requests to authorize or cancel a representative.

Note: You must use the 2020 version of the tax software to electronically submit 2020 requests through the transmission web service for authorizing or cancelling a representative until 8:00 p.m. on Friday, February 4, 2022, (Eastern Time). When the transmission web service for authorizing or cancelling a representative re-opens at 6:00 a.m. on Monday, February 7, 2022, (Eastern time), it will only accept the signature page format, which is available in the 2021 version of the software.
