EIN in New Hampshire (NH)
How to get an EIN for your New Hampshire business or LLC. The EIN is a federal number from the IRS. Non-residents file Form SS-4 by fax with a passport number — no SSN required. $49 with ein.so.
A New Hampshire EIN is identical to an EIN obtained in any other state. The IRS issues one 9-digit Employer Identification Number (XX-XXXXXXX) per business entity, and that number works nationwide. New Hampshire does not issue its own EIN. What ties your EIN to New Hampshire is your business itself — most often a New Hampshire LLC registered with the New Hampshire Secretary of State. This guide explains how non-residents get an EIN for a New Hampshire entity without an SSN, how the federal process works, and what to do after the IRS assigns your number.

State vs Federal
Is a New Hampshire EIN Different From a Federal EIN?
No. A New Hampshire EIN is the same federal EIN issued by the IRS to businesses in all 50 states. New Hampshire does not issue a separate state version of an EIN. The number is federal, the format is the same, and it works nationwide.
Your federal EIN and any New Hampshire state registration serve different purposes. The EIN identifies your business to the IRS for federal tax filing, banking, and payment processors. A New Hampshire state tax registration, issued by the New Hampshire Department of Revenue Administration, applies to certain state-level activities. You may need both depending on what your business does in the state.
| Identifier | Issued By | Used For |
|---|---|---|
| Federal EIN | IRS | Federal tax, banking, Form SS-4 |
| NH state tax ID | NH Dept. of Revenue Administration | State-level business taxes |
| LLC registration | NH Secretary of State | Legal formation of the entity |
Your EIN does not replace state registration, and a state tax ID does not replace the EIN. Confirm whether your New Hampshire activities require state registration with a New Hampshire CPA, since rules change. See how to get an EIN for the full federal process.
No SSN Needed
Can a Non-Resident Get an EIN for a New Hampshire LLC Without an SSN?
Yes. Non-residents get an EIN for a New Hampshire LLC without an SSN or ITIN. You enter your passport number on Form SS-4 Line 7b instead. The IRS online EIN tool requires an SSN, so non-residents use the fax method to 855-215-1627.
The fax route is the standard path for international founders forming a New Hampshire LLC. The IRS accepts a passport number as the responsible-party identification, which means you never need a US Social Security Number to receive an EIN. This is the single most common point of confusion, and it stops many non-residents who try the online tool and get blocked.

Form SS-4 Field Guide for New Hampshire Non-Residents
| SS-4 Field | What to Enter |
|---|---|
| Line 1 (Legal name) | Your New Hampshire LLC name |
| Line 4 (Address) | Your foreign mailing address |
| Line 7a (Responsible party) | Your full name as on your passport |
| Line 7b (SSN/ITIN/EIN) | Your passport number |
| Line 8a (LLC) | Yes, with number of members |
| Line 10 (Reason) | Started new business |
| Line 16 (Principal activity) | E.g., "e-commerce," "consulting," "software" |
The most common rejection cause for non-residents is address formatting. International addresses do not map cleanly to the SS-4 fields, and the IRS rejects malformed entries. See the full SS-4 form guide and the complete EIN application process.
Methods Compared
What Are the Ways to Get an EIN in New Hampshire?
There are four IRS methods to get a New Hampshire EIN: online, fax, phone, and mail. The method that works depends on whether you have an SSN. Non-residents use fax because the online tool requires an SSN.
| Method | Speed | Cost | Works for Non-Residents |
|---|---|---|---|
| Online | Instant | $0 | No (SSN required) |
| Fax (855-215-1627) | 4-7 business days | $0 | Yes |
| Phone (intl applicants) | Same call | $0 | Yes, with US business hours |
| 4-6 weeks | $0 | Yes |
The phone option requires calling the IRS during US business hours, which means costly international calls for many non-residents. Mail is the slowest path at 4-6 weeks. Fax is the practical choice, and it is the method ein.so uses. See EIN cost and EIN processing time for full details.
