IRS EFIN Application Summary: Requirements, Suitability, and Timeline

An EFIN application is submitted online through the IRS e-Services portal, and it takes the IRS up to 45 days to process after you file it, so start well before filing season. Before you can open the application itself, you need a Preparer Tax Identification Number (PTIN) and an ID.me-verified e-Services account. Once the application is in, non-credentialed principals and responsible officials have to be fingerprinted, and everyone listed on the firm goes through a suitability check covering tax compliance, criminal history, credit, and prior e-file conduct.¹

What You Need Before You Start

Two items have to be in place before the EFIN application will open to you.

A PTIN for Every Preparer

Every person in the firm who prepares or helps prepare federal returns for compensation needs their own PTIN. That includes staff who work on returns but don’t sign them, and interns handling simple filings.² A new PTIN or annual renewal costs $18.75 for 2026, and PTINs expire at the end of each calendar year.³

An IRS E-Services Account for Each Principal and Responsible Official

The e-Services portal is where you submit and manage the application.⁴ Identity verification runs through ID.me, which requires a government-issued photo ID (driver’s license, state ID, or passport) and a smartphone or webcam for the selfie step.⁵ Every principal and responsible official has to register individually. Credentials cannot be shared.

Filling Out the Application

Inside e-Services, you’ll work through the e-file application, which collects details about the firm and the people running it. The EFIN belongs to the firm, not any individual, so get the business structure right.

Have the following ready:

Firm details: legal business name, primary address, and Employer Identification Number. Sole proprietors may use a Social Security Number instead of an EIN.⁶
Information on each principal and responsible official: full name, address, Social Security Number, and date of birth for anyone who controls, manages, or directs the firm, or is authorized to act for it.¹
Professional credentials for any principal or responsible official who is a CPA, attorney, or Enrolled Agent, including current license status and number.¹
Your 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 have to be fingerprinted electronically through an IRS-authorized vendor. After you submit the application, the e-file application summary page displays a scheduling link containing a unique ID for each individual, so each person books their own appointment.¹ The IRS will not advance the suitability check until fingerprints are on file, so don’t let this step sit.

The Suitability Check

Once the application is submitted and fingerprinting is complete, the IRS runs a background review on the firm and every listed principal and responsible official. The check looks at four areas:¹

Tax compliance: whether all required returns are filed and balances are paid.
Credit history.
Criminal background.
Prior e-file compliance, meaning any past violations of IRS e-file rules.

What Trips Applicants Up

On the tax side, the Internal Revenue Manual identifies specific triggers: unfiled returns for any of the last six tax years, outstanding 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.⁷

For criminal history, the IRS weighs felony convictions involving financial crimes, dishonesty, breach of trust, tax offenses, fraud, identity theft, and similar conduct. The lookback period varies by credential type, but convictions within the past five to ten years carry the most weight.⁸

The credit review is the least transparent piece. The IRS lists “credit check” as a suitability denial code without publishing a minimum score or disqualifying events.⁷ If your credit report carries significant derogatory marks, clean up what you can before applying.

Timeline and Checking Status

The IRS says processing can take up to 45 days from the submission date.¹ Straightforward applications from credentialed professionals sometimes clear faster. Fingerprinting delays or suitability issues can push things well past that window. You can check status at any time by logging into your e-Services account.

If approved, the IRS mails an acceptance letter that includes your EFIN. If denied, the letter explains the specific reasons. If processing runs significantly past 45 days with no update, contact the IRS e-help Desk at 866-255-0654, Monday through Friday, 6:30 a.m. to 6:00 p.m. Central time.⁹

If You’re Denied

A denial is reviewable. Within 30 calendar days of the date on the denial letter, submit a written response to the IRS address printed on it. The IRS will reconsider and either withdraw the denial and accept you, or sustain it and issue a second denial letter.¹⁰

If a second denial comes, you have another 30 calendar days to file a written appeal to the IRS Independent Office of Appeals. The appeal must set out detailed reasons and supporting documentation for why the denial should be reversed. Missing either 30-day window ends your right to further review, so mark the dates immediately.¹⁰

Keeping the EFIN After You Get It

Approval starts a set of ongoing obligations that catch new providers off guard.

One EFIN per physical office. If you open a second location that transmits returns, you need a second application.¹¹
Not transferable. If you sell the business, the buyer applies for their own EFIN.¹¹
The 30-day update rule. Any change to firm information, including address, phone, or the addition or removal of principals or responsible officials, has to be reflected in the e-file application within 30 days. The IRS can deactivate the EFIN if you don’t.¹¹
Annual PTIN renewal. The EFIN itself does not expire, but every preparer’s PTIN must be renewed each year before filing season.³
No sharing. Letting an unauthorized person or firm use your EFIN to transmit returns is one of the fastest ways to lose it.

If you detect that your EFIN has been compromised or used without authorization, contact the e-help Desk immediately at 866-255-0654.⁹

One obligation worth flagging now even though it sits outside the application itself: holding an EFIN means you’re a financial institution under the Gramm-Leach-Bliley Act, and the FTC’s Safeguards Rule requires a written information security program covering a designated qualified individual, a written risk assessment, access controls, encryption of customer data in storage and in transit, multi-factor authentication, data disposal within two years of last use, staff training, and a written incident response plan.¹² It applies to solo preparers working from home the same way it applies to large firms, though the plan’s complexity will scale.¹³
