An Electronic Filing Identification Number (EFIN) is issued by the IRS and authorizes you to electronically file tax returns on behalf of clients.
Why you need one
Most clients expect e-filing, and preparers who file electronically for others generally need an EFIN. Paper-only filing is impractical for a modern practice.
The application process
You apply through the IRS e-file application, which includes a suitability check. Because processing can take time, start the application well before filing season.
Common questions
Frequently asked questions
