In order to electronically file tax returns, you must first obtain an Electronic Filer's Identification Number (EFIN), assigned to you by the IRS. 

To apply for an EFIN, complete Form 8633 and submit to the IRS.  We recommend doing this as soon as possible, as it typically takes up to 45 days for the IRS to process the application and issue you an EFIN.

You can fill out Form 8633 and submit it online by registering with e-services from the IRS website.  To register for e-services, click here.
