Authorized IRS E-File Provider: Application, Suitability, and Approval

To become an Authorized IRS e-file Provider, you create an IRS online account, verify your identity through ID.me, complete the e-file application inside the IRS e-services portal, pass a suitability and background check (which for most applicants includes fingerprinting), and wait roughly 45 days for the IRS to review everything and issue your Electronic Filing Identification Number (EFIN).¹ The EFIN is what authorizes your firm to transmit federal returns electronically on behalf of clients.

The steps below walk through what to gather, what the application asks, and what the IRS does with your submission before it approves you.

Set Up Your IRS Account and Verify Your Identity

The application lives inside IRS e-services, and you can only reach it after creating an IRS online account. Identity verification runs through ID.me. You will need a Social Security number or ITIN, a government-issued photo ID (driver’s license, state ID, or passport), and a mobile phone with a camera for the selfie or video step.² Once your ID.me credentials are active, they unlock the e-services portal.³

Every principal and responsible official on the application needs to do this individually. A principal is anyone who owns 5 percent or more of the firm, or, if no single partner holds at least 5 percent, the person authorized to act for the business in legal or tax matters. A responsible official is the person who oversees e-file operations at a location and serves as the IRS’s first point of contact. Both roles carry personal accountability for the firm’s compliance.⁴

Get a PTIN If You Will Prepare Returns

Anyone who prepares or helps prepare federal tax returns for compensation also needs a Preparer Tax Identification Number (PTIN), which is separate from the EFIN. The PTIN identifies the individual preparer; the EFIN identifies the firm’s authorization to transmit. A first-time PTIN can be obtained online in about 15 minutes for a non-refundable fee of $18.75.⁵ Get it before you start the e-file application if you plan to prepare returns yourself.

Fingerprinting or Professional Credentials

The IRS requires every principal and responsible official to be fingerprinted through the agency’s authorized vendor. You schedule the appointment from a link on the application summary page. As an alternative, you can submit an ink fingerprint card (Form FD-258) through the FBI, though the electronic route is faster and more common.⁴

Three categories of professionals can skip fingerprinting by entering their professional credentials directly in the application: attorneys in good standing with the bar of any U.S. state or territory, licensed Certified Public Accountants, and enrolled agents. Each must provide a credential number, jurisdiction, and expiration date. The exemption does not apply if the license is expired or the professional is under suspension or disbarment.⁶

Choose Your Provider Category

The application asks which provider category or categories describe your role in the filing chain. The choice determines which return types you can handle, so match it to how your firm actually operates.

Electronic Return Originator (ERO) is the most common category. An ERO collects the taxpayer’s information, prepares or accepts the return, and originates the electronic submission. Most tax preparation firms apply as EROs.
Transmitter sends return data directly to the IRS through the Modernized e-File (MeF) system. Large firms that run their own transmission infrastructure need this designation, and transmitters receive a separate five-digit Electronic Transmitter Identification Number (ETIN) in addition to the EFIN.⁷
Software Developer builds the software used to format and transmit returns. Firms writing tax preparation or transmission software need this category.

You can select more than one. Many firms operate as both an ERO and a transmitter. The application also asks which form types you plan to file (1040, 1120, 1065, 990, 941, and others), so check every form relevant to your practice.⁸

Complete the Application

The e-file application collects detailed information about the business and the people running it. You will enter the firm’s legal name exactly as it appears on your tax return along with the firm’s Employer Identification Number (EIN). Sole proprietors without employees use their Social Security number instead.⁸

For each principal and responsible official, the system asks for Social Security numbers, home addresses, titles within the firm, and professional credentials if applicable. It also requires a primary contact for all correspondence about the application. Match names and EINs to your IRS records exactly. Small discrepancies trigger manual review and add weeks to processing.

You must disclose any prior participation in the e-file program and any prior suspensions or expulsions. Disclose them. The background check will surface a prior suspension either way, and hiding it becomes its own violation.

Every principal and responsible official listed on the application signs it digitally, certifying the information is accurate. Once the last signature is in, you submit.

What the IRS Checks (Suitability)

During the review, the IRS runs a suitability check on the firm and on every principal and responsible official. The check covers three areas: tax compliance, criminal history, and prior problems with the e-file program.⁴

Grounds for denial include a criminal conviction, outstanding tax debts, unfiled returns, misrepresentation on the application, or a prior suspension from the e-file program. An indictment alone (not only a conviction) can be enough to block participation. Clean tax compliance and honest disclosures are the strongest protection against a denial.

Review Timeline and What You Receive

The IRS typically takes up to 45 days to process the application, and delays are common during peak filing season.¹ During that window, the agency runs the background and tax compliance checks and may request additional documentation. Watch your e-services dashboard; if you miss a request for information, the application stalls indefinitely.

If approved, the IRS sends an acceptance letter with your EFIN, the six-digit number that authorizes your firm to transmit electronic returns.¹ Firms approved as transmitters also receive a five-digit ETIN, which establishes the actual transmission channel. After receiving an ETIN, you must designate at least one MeF Internet Transmitter (a responsible official or delegated user) through the e-services authorities menu.⁷

Assurance Testing for Transmitters and Developers

Transmitters and software developers cannot start sending live returns as soon as they are approved. The IRS requires them to pass the Assurance Testing System (ATS), an annual process that validates the software’s ability to format and transmit returns correctly. Testing involves completing IRS-provided scenarios for each supported form type. The IRS e-Help Desk handles ATS questions at 866-255-0654.⁹ EROs that use a third-party transmitter do not need to go through ATS themselves.

What You Have to Do After Approval

Approval brings ongoing obligations. The IRS monitors authorized providers, and slipping on these rules can cost you your EFIN.

Report changes to ownership, addresses, phone numbers, or the people listed on your application within 30 calendar days.¹⁰
Transmit each completed return to the IRS within three calendar days.¹¹
Retain each taxpayer’s Form 8879 (electronic filing authorization) for three years from the later of the return’s due date or the date the IRS received it.¹¹
Give every taxpayer a copy of the completed return you filed for them.
Never charge a fee for direct deposit of a refund.¹¹
Do not use “Internal Revenue Service” or “IRS” in your firm name or advertising, other than the official IRS e-file logo.¹¹
Do not knowingly employ or accept help from anyone suspended or expelled from the e-file program.¹¹

Protect your EFIN and its associated passwords. If someone gains unauthorized access, they can transmit fraudulent returns under your firm’s name, and the IRS treats EFIN security as the provider’s responsibility.

If Your Application Is Denied

You have 30 calendar days from the date of the denial letter to submit a written response explaining why the decision should be reversed. The IRS will reconsider and either withdraw the denial or sustain it in a second letter. From that second letter, you have another 30 days to file a formal appeal to the IRS Office of Appeals with detailed reasons and supporting documentation. Missing either 30-day window permanently ends the right to contest the decision.¹² The clock runs from the date on the letter, not the date you receive it, so if you think a denial is coming, start gathering documentation before the notice arrives.
