EFILE is an automated service that allows approved tax preparation service providers and discounters to send individual income tax return information to the Canada Revenue Agency (CRA) directly from 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.
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.
