Federal vs State
Is a New Mexico EIN Different From a Federal EIN?
No. A New Mexico EIN is the same as a federal EIN. The IRS issues one 9-digit number that works in all 50 states. New Mexico does not assign its own EIN. The state issues a separate tax registration through the Taxation and Revenue Department for state-level obligations.
Your EIN and your New Mexico state tax registration serve different purposes. Keep them separate in your records.
| Identifier | Issued By | Used For |
|---|---|---|
| Federal EIN | IRS | Federal taxes, banking, payment processors |
| NM state tax ID | NM Taxation and Revenue Department | State gross receipts and withholding |
The EIN does not replace state registration. If your New Mexico LLC has state tax obligations, you may need both. See our state tax ID guide and the EIN cost breakdown for the full picture.
How to Apply
How Do You Get an EIN in New Mexico?
You get an EIN in New Mexico by submitting IRS Form SS-4 through one of four methods. US residents with an SSN use the instant online tool. Non-residents without an SSN fax the SS-4 to 855-215-1627. The process is identical to every other state.
| Method | Speed | Cost | SSN Required |
|---|---|---|---|
| Online | Instant | $0 | Yes |
| Fax | 4-7 days | $0 / $49 | No |
| Phone | Same day | $0 | US callers |
| 4-6 weeks | $0 | No |
The online tool at irs.gov is fastest but requires an SSN or ITIN. Non-residents must use fax. See the full how to get an EIN walkthrough and the EIN processing time details.
Steps to Apply as a Non-Resident
Form Your New Mexico LLC
Gather Your Documents
Complete Form SS-4
Fax and Receive Your EIN
Read the line-by-line SS-4 form guide before filing.
No SSN Needed
Can You Get a New Mexico EIN Without an SSN?
Yes. Non-residents get an EIN for a New Mexico LLC without an SSN or ITIN. You enter your passport number on Form SS-4 Line 7b instead. The IRS online tool blocks applicants without an SSN, so you fax the SS-4 to 855-215-1627. The IRS still issues the EIN.
This is the single biggest source of confusion for foreign founders. The online tool rejects you not because you are ineligible, but because it cannot verify a non-US identity. The fax path solves this.
| SS-4 Field | Non-Resident Entry |
|---|---|
| Line 1 (Legal name) | Your New Mexico LLC name |
| Line 4 (Address) | Your home-country address |
| Line 7a (Responsible party) | Your full name as on your passport |
| Line 7b (SSN/ITIN/EIN) | Your foreign passport number |
| Line 10 (Reason) | Started new business |
| Line 16 (Principal activity) | E.g., "e-commerce," "software," "consulting" |
The most common rejection cause is malformed international address formatting. The IRS silently rejects addresses that do not fit the SS-4 layout. ein.so reformats your address to an IRS-accepted style. See EIN without SSN and EIN for non-residents for more.
