As a paid preparer, in order to e-file tax returns, you must have an Electronic Filing Identification Number (EFIN) assigned to you by the IRS.
To apply for an EFIN, go to the
IRS e-Services website and complete the e-file application. If you need help completing your e-file application, call the IRS e-help desk at 1-866-255-0654.
It can take up to 45 days for the IRS to process your application and issue you an EFIN.
