PTIN and EFIN sound like two versions of the same IRS account. They solve different problems. One follows a person. The other belongs to a firm.
The difference matters when you choose between working for an established office and opening your own practice. A seasonal employee may need an individual PTIN while using the employer’s approved e-file operation. A sole proprietor who prepares and e-files client returns generally needs an individual PTIN plus firm approval as an authorized IRS e-file provider.

What a PTIN does
The IRS generally requires a PTIN from a person who is compensated for preparing, or substantially assisting in preparing, all or substantially all of a federal tax return or claim for refund. Every affected preparer needs a separate number. An office cannot place one owner’s PTIN on work performed by several paid preparers.
The PTIN identifies the preparer in the paid-preparer section of a return when the signing rules apply. A paid non-signing preparer can still need a PTIN even when another person reviews and signs the return. Clerical help that performs typing, reproduction, or other mechanical assistance does not become a preparer on that fact alone. The IRS walks through these distinctions in its PTIN scenarios.
Current 2026 PTIN facts
- The application or renewal fee is $18.75 for 2026 and is non-refundable.
- Applicants must be at least 18 years old.
- Most first-time online applicants can obtain a PTIN in about 15 minutes when the application is straightforward.
- Paper Form W-12 processing can take 6 weeks.
- A PTIN is issued for a calendar year and expires on December 31.
- All enrolled agents need an active PTIN. Attorneys and CPAs need one when compensated for preparing or assisting with covered federal returns or refund claims.
Use the IRS PTIN account for the application. Avoid services that present their own handling fee as the government fee.
What an EFIN does
An EFIN identifies a business or organization that completed the IRS e-file application, passed the required suitability review, and was accepted as an authorized IRS e-file provider. A sole proprietor can be the firm, but the EFIN still belongs to that approved firm rather than to the owner as a portable personal credential.
A return-preparation firm that wants to e-file for clients generally selects the Electronic Return Originator, or ERO, provider option. The firm application identifies principals, responsible officials, and a primary contact. Depending on professional status and the application facts, principals and responsible officials may need to schedule fingerprinting with the IRS-authorized vendor.
The suitability check may include tax compliance, criminal background, credit, and prior IRS e-file compliance. Approval can take up to 45 days. The IRS provides the EFIN in an acceptance letter after approval. See the current authorized e-file provider application steps and Publication 3112 before applying.
EFIN ownership has practical consequences
- An employee works inside the authorized firm’s e-file operation and does not take the EFIN when leaving.
- An EFIN cannot be sold, gifted, or transferred with a practice.
- A change in ownership, legal structure, principals, responsible officials, address, or provider activity may require an application update or a new application.
- The firm should compare its IRS e-file application activity with actual filing records and respond to unexplained volume.
- Software access does not create e-file authorization. The firm still needs IRS approval for the role it performs.
Who usually needs which number
| Situation | PTIN | EFIN |
|---|---|---|
| Seasonal preparer employed by an established office | Own active PTIN when preparing covered returns for compensation | Uses the employer firm’s authorized e-file operation |
| Independent preparer who prepares and e-files client returns | Own active PTIN | Firm generally applies for its own EFIN and appropriate provider role |
| Owner who hires other paid preparers | Each preparer who meets the federal rule has a separate PTIN | The approved firm’s EFIN covers e-file activity within that firm |
| Unpaid volunteer preparing returns | Generally outside the paid-preparer PTIN rule | Uses the sponsoring program’s authorized filing process, when applicable |
| Administrative employee who performs mechanical data entry only | May fall outside the PTIN rule if the work stays clerical | No separate EFIN for clerical work inside the firm |
Facts control. A job title does not settle whether someone substantially assisted with preparation. When the line is unclear, review the IRS scenarios and the person’s actual duties before any return work begins.
A sensible application order for a new independent firm
- Define the owner, legal entity, business address, return scope, and who will act as principals and responsible officials.
- Obtain or renew each paid preparer’s PTIN for the calendar year of preparation.
- Create or confirm the IRS online account access needed for e-Services.
- Submit the firm’s e-file application, choose the correct provider option, and list the required people.
- Complete fingerprinting when the application requires it.
- Allow up to 45 days for suitability review and answer IRS requests promptly.
- Wait for acceptance and the EFIN before representing the firm as an authorized e-file provider.
- Configure professional software and access controls around the approved firm identity.
- Check state registration, business licensing, security, insurance, record-retention, and engagement requirements before taking client data.
Apply early. Tax software setup, bank product review, security controls, state registrations, and staff training can each add time after the EFIN arrives.
What neither number proves
A PTIN and EFIN are federal identification and e-file controls. They do not establish all of the qualifications a client, employer, or regulator may care about.
- Neither number is an IRS endorsement of the person or firm.
- A PTIN does not prove the holder passed a tax exam or completed a specific course.
- An EFIN does not certify that every employee can prepare every return type.
- Neither number replaces a state registration, license, bond, or education requirement.
- Neither number creates unlimited representation rights before the IRS.
- Neither number satisfies the firm’s security, due-diligence, signature, disclosure, or record-retention duties.
The IRS explains that PTIN-only preparers without another credential or Annual Filing Season Program participation generally have no representation rights for returns prepared and signed after December 31, 2015. Attorneys, CPAs, and enrolled agents have unlimited representation rights; qualifying AFSP participants have limited rights. Read the IRS guide to preparer credentials and representation rights before describing services to clients.
Preseason verification checklist
- Every affected preparer has an active PTIN for the filing calendar year.
- The firm’s IRS e-file application lists current principals, responsible officials, contacts, address, and provider roles.
- EFIN return counts are reconciled with the firm’s filing records.
- Departed staff have lost software, portal, email, and e-Services access.
- State and local preparer requirements have been checked for the firm, preparers, and clients served.
- Training and review limits match the return types the firm will accept.
- The written information security plan matches the systems and vendors actually used.

Common questions
What readers ask next
Do I need both a PTIN and an EFIN?
You generally need your own active PTIN if you prepare or substantially assist with federal returns for compensation. A firm that wants to originate or transmit client returns through IRS e-file needs firm-level approval and an EFIN. An employee may prepare returns under an employer’s EFIN but cannot share the employer’s PTIN.
How much is a PTIN for 2026?
The IRS lists the 2026 PTIN application or renewal fee as $18.75. The payment is non-refundable. Check the IRS PTIN page before paying because fees are set by year.
How long does an EFIN application take?
The IRS says approval can take up to 45 days from submission. The application includes firm information, principals and responsible officials, the provider role, and a suitability review. Some people must complete fingerprinting.
Can I use a former employer’s EFIN?
No. An EFIN belongs to the approved firm, is not transferable, and must be protected from unauthorized use. A new firm should submit its own IRS e-file application.
Does a PTIN mean the IRS certified a preparer?
No. A PTIN is an identification requirement for paid preparation. It does not establish a professional credential, state registration, course completion, general representation rights, or IRS approval of the preparer’s skill.
