If you're new to the tax preparation industry, two acronyms will come up immediately: PTIN and EFIN. They sound similar, but they serve very different purposes, and confusing them can lead to compliance issues that put your business at risk.
Here's a clear, side-by-side breakdown of what each one is, who needs it, and how to get it.
What Is a PTIN?
A Preparer Tax Identification Number (PTIN) is a unique ID issued by the IRS to identify paid tax return preparers. It was established under IRC § 6109(a)(4) and is required for every individual who prepares or assists in preparing federal tax returns for compensation.
Key PTIN Facts:
- Required for every paid preparer, no exceptions
- Issued to individuals, not businesses
- Must appear on every return you sign
- Renewed annually by December 31 (fee: $19.75/year as of 2024)
- Apply or renew at IRS.gov
Think of your PTIN as your personal tax preparer license plate, it identifies you as the preparer on every return.
What Is an EFIN?
An Electronic Filing Identification Number (EFIN) is issued by the IRS to authorize a tax preparation firm or individual to electronically submit tax returns to the IRS. It's tied to your business location, not just you as an individual.
Key EFIN Facts:
- Required if you e-file 11 or more returns per year (IRS mandate under IRC § 6011)
- Issued to businesses or individuals operating a tax business
- Requires an IRS suitability check (credit history, criminal background, tax compliance)
- Tied to a specific business address, you may need multiple EFINs for multiple locations
- Apply through the IRS e-Services portal
- No annual fee, but must be kept current with IRS records
Think of your EFIN as your business's authorization to transmit returns electronically, it's the key that lets you actually send returns to the IRS on behalf of clients.
PTIN vs. EFIN: Side-by-Side Comparison
| Feature | PTIN | EFIN |
|---|---|---|
| Issued to | Individual preparer | Business / firm |
| Purpose | Identifies the preparer | Authorizes e-filing |
| Required when | Preparing any paid return | E-filing 11+ returns/year |
| Annual renewal | Yes ($19.75) | No (keep info current) |
| Suitability check | No | Yes (credit + background) |
| Tied to location | No | Yes |
Do You Need Both?
In most cases, yes. If you're running a tax preparation business and filing returns electronically for clients (which is the industry standard), you need both:
- Your PTIN to legally sign and prepare returns
- Your EFIN to electronically transmit those returns to the IRS
The only exception is if you work under someone else's EFIN (for example, as an employee of an established tax firm). In that case, you still need your own PTIN, but the firm's EFIN covers the e-filing.
How Long Does It Take?
- PTIN: Issued immediately upon online application
- EFIN: Can take 4–6 weeks due to the suitability check, apply early before tax season
