Your EFIN is the credential that lets your business transmit returns to the IRS. The application is free — but it's a process. Here's each step, in order, with no surprises.

What an EFIN is

An Electronic Filing Identification Number is issued by the IRS to businesses approved as e-file providers. When you hold your own EFIN, you are an ERO — an Electronic Return Originator. Returns transmit under your number, your firm's name is on the infrastructure, and you keep every dollar of your prep fees.

Step 1 — Create an IRS e-Services account

Go to the IRS e-Services portal and create an account. You'll verify your identity through the IRS's identity-proofing process, which requires personal information and documentation. Every principal and responsible official of your business needs their own account.

Step 2 — Submit the e-file application

Inside e-Services, complete the application to become an authorized e-file provider, selecting Electronic Return Originator as your provider option. You'll supply business details, ownership information, and identify your responsible officials.

Step 3 — Pass the suitability check

The IRS runs a suitability check on the firm and each principal: a credit check, a tax-compliance check (your own filings need to be clean and current), and a background check. Some applicants are required to submit fingerprints. This is the step that takes the time — commonly around 45 days, sometimes longer.

Step 4 — Receive your EFIN and register it

Once approved, your EFIN arrives and you register it with your professional tax software and your bank-product provider. At that point you're transmitting under your own number as an ERO.

What to do while you wait

• Prepare under an authorized provider so the season doesn't wait on the IRS
• Finish your training and practice returns
• Set up your entity, business bank account, and pricing
• Get your software and bank-product applications ready to activate
• Keep your personal tax filings clean — suitability checks look

Frequently asked questions

How long does it take to get an EFIN?

Plan on roughly 45 days from application to approval, sometimes longer if fingerprinting or follow-up is required. Apply in the off-season so tax season doesn't wait on the IRS.

Does it cost money to get an EFIN?

The IRS does not charge a fee for the EFIN application. Your only potential costs are incidentals like fingerprinting, if required.

Can I prepare returns while I wait for my EFIN?

Yes. With a valid PTIN you can prepare returns and transmit them under an authorized provider's EFIN, such as a service bureau, while your own application is processing.
