IRS EFIN Application Summary: Requirements and Suitability Check

To get an EFIN, you submit an e-file application through the IRS e-Services portal, complete fingerprinting if you are not a credentialed professional, and pass a suitability check that reviews your tax compliance, credit, criminal history, and any prior e-file record. The IRS says the process can take up to 45 days, so an EFIN application should go in well before filing season begins.1Internal Revenue Service. Become an Authorized E-File Provider The EFIN belongs to your firm, not to you personally, and it is required to transmit even a single federal return electronically.

What You Need Before You Start

Two items must be in place before the EFIN application itself is worth opening.

A PTIN for Every Preparer

Every individual in your firm who prepares or helps prepare federal returns for compensation needs their own Preparer Tax Identification Number. That includes employees who work on returns but never sign them, and interns handling simple filings.2Internal Revenue Service. Frequently Asked Questions: Do I Need a PTIN? A new PTIN or annual renewal costs $18.75 for 2026, and PTINs expire at year-end.3Internal Revenue Service. IRS Reminds Tax Pros to Renew PTINs for the 2026 Tax Season

An E-Services Account for Each Principal and Responsible Official

The e-Services portal is where the application is filed and later managed.4Internal Revenue Service. E-Services Access runs through ID.me, so each person will need a government-issued photo ID (driver’s license, state ID, or passport) and a smartphone or webcam for the selfie verification step.5Internal Revenue Service. New Identity Verification Process to Access Certain IRS Online Tools and Services Every principal and responsible official listed on the application must register individually. Shared credentials are not allowed.

Filling Out the E-File Application

Inside e-Services, the e-file application asks about your business and the people who run it. Have the following ready:

  • Legal business name, primary address, and Employer Identification Number. Sole proprietors may use a Social Security Number in place of an EIN.6Internal Revenue Service. FAQs About Electronic Filing Identification Numbers (EFIN)
  • Full name, address, Social Security Number, and date of birth for each principal and responsible official — anyone who controls, manages, or directs the firm or is authorized to act on its behalf.1Internal Revenue Service. Become an Authorized E-File Provider
  • Current license status and number for any principal or responsible official who is a CPA, attorney, or Enrolled Agent.1Internal Revenue Service. Become an Authorized E-File Provider
  • Your e-file provider option. Most firms select Electronic Return Originator (ERO), which covers originating and transmitting returns.

Fingerprinting for Non-Credentialed Applicants

If a principal or responsible official is not a licensed CPA, attorney, or Enrolled Agent, they must be fingerprinted electronically through an IRS-authorized vendor. After submission, the e-file application summary page displays a scheduling link containing a unique ID tied to each individual, so each person books their own appointment.1Internal Revenue Service. Become an Authorized E-File Provider The IRS will not run your suitability check until fingerprints are on file, so treat this as urgent rather than optional.

The Suitability Check

Once the application is in and fingerprints are received, the IRS runs a background review of the firm and every listed principal and responsible official. The review covers four areas:1Internal Revenue Service. Become an Authorized E-File Provider

  • Tax compliance — whether required returns are filed and balances paid.
  • Credit history.
  • Criminal background.
  • Prior e-file compliance.

On the tax side, the Internal Revenue Manual identifies specific triggers for denial: unfiled returns in any of the last six tax years, balances in currently-not-collectible status, pending offers in compromise, and assessed fraud or negligence penalties. Delinquency penalties, estimated tax penalties, and failure-to-pay balances also appear on the denial code list.7Internal Revenue Service. 3.42.10 Authorized IRS E-File Providers

For criminal history, the IRS focuses on felony convictions involving financial crimes, dishonesty, breach of trust, tax offenses, fraud, and identity theft. Lookback periods vary by credential type, and convictions within the past five to ten years carry the most weight.8Internal Revenue Service. Return Preparer Suitability

The credit check is less transparent. “Credit check” appears as a denial code, but the IRS does not publish a minimum score or a list of disqualifying events.7Internal Revenue Service. 3.42.10 Authorized IRS E-File Providers If your report has significant derogatory marks, resolve what you can before you apply.

How Long It Takes and How to Track It

The IRS gives itself up to 45 days from the submission date.1Internal Revenue Service. Become an Authorized E-File Provider Clean applications from credentialed professionals sometimes clear faster; fingerprinting delays or suitability issues push things past that window. Status is visible anytime inside your e-Services account.

Approval arrives by letter and includes your EFIN. A denial letter explains the specific reasons. If processing stretches well beyond 45 days without an update, call the IRS e-help Desk at 866-255-0654, Monday through Friday, 6:30 a.m. to 6:00 p.m. Central.9Internal Revenue Service.

If You’re Denied

A denial is not final. You have 30 calendar days from the date of the denial letter to submit a written response to the address on the letter. The IRS will reconsider and either withdraw the denial or sustain it with a second denial letter.10Internal Revenue Service. 8.7.13 E-File Cases

A second denial opens another 30-day window to file a written appeal to the IRS Independent Office of Appeals. That appeal needs detailed reasons and supporting documentation. Missing either 30-day deadline ends your right to further review, so calendar those dates the day the letter arrives.10Internal Revenue Service. 8.7.13 E-File Cases

After Approval: What You Have to Keep Doing

The EFIN itself does not expire, but keeping it in good standing carries ongoing obligations.11Internal Revenue Service. How to Maintain, Monitor and Protect Your EFIN

  • A separate EFIN is required for every physical office where e-file transmissions occur. Open a second location, file a second application.
  • EFINs are not transferable. If you sell the business, the buyer applies for their own.
  • Any change to firm information — address, phone, adding or removing a principal or responsible official — must be updated in the e-file application within 30 days. Failure to update can lead to deactivation.
  • Every preparer’s PTIN must be renewed each year before filing season.3Internal Revenue Service. IRS Reminds Tax Pros to Renew PTINs for the 2026 Tax Season
  • Never let an unauthorized person or firm transmit under your EFIN. The IRS monitors usage continuously.

If you suspect your EFIN has been compromised or used without authorization, call the e-help Desk at 866-255-0654 right away.9Internal Revenue Service. E-Help Desk for Tax Professionals

One boundary worth naming before you start work: holding an EFIN also brings you under the FTC Safeguards Rule, which requires a written information security program regardless of firm size.12Federal Trade Commission. FTC Safeguards Rule: What Your Business Needs to Know That is a separate obligation from the EFIN application itself, but it attaches the moment you begin handling client data, so plan for it alongside the application rather than after.
