The EFILE and ReFILE services are open for transmission from Monday, February 23, 2026, at 8:30 a.m. (Eastern Time), until Friday, January 29, 2027. You can electronically file your clients' 2018, 2019, 2020, 2021, 2022, 2023, 2024 and 2025 initial personal income tax and benefit returns using EFILE service and you can file your clients' amended T1 returns for 2022, 2023, 2024 and 2025 using ReFILE.
EFILE is an automated service that allows approved tax preparation service providers and discounters in Canada to electronically file their clients' current and first seven prior years' income tax and benefit return information to the Canada Revenue Agency (CRA) directly from their EFILE–certified tax preparation software.
Taxpayers may take their tax slips and supporting documents to a registered tax preparer and for a fee, the tax preparer will prepare their return and send it to us electronically using EFILE.
Access to the EFILE Electronic Filing Service is limited solely for the purpose of the electronic filing of any return of income. Any other use is prohibited.
Many new enhancements are implemented to improve EFILE services. To keep up to date on the latest news and important dates, visit the EFILE news and program updates webpage.
Any firm, organization, or individual who provides tax preparation services can apply, as long as they meet the definition and requirements of an applicant and pass the suitability screening criteria.
For the latest news, updates on enhancements and important dates.
EFILE "certified" tax preparation software means that the developer of the tax preparation software has gone through a process with the Canada Revenue Agency (CRA) to verify that their product is compatible with the CRA EFILE electronic tax filing service.
To renew your account, sign in with your EFILE number and password and select "Renew account" on the resulting webpage. Yearly renewal is mandatory for your continued participation in electronic filing. An invitation to renew your account will be sent each year towards the end of October.
Changes in your business may result in changes to the data you provided to us at the time you applied for, or last renewed your participation in, electronic filing. An account maintenance option is available to all registered users of EFILE.
