Walks through the IRS Form SS-4 EIN application, flags the trip-wires that cause IRS rejections, and outputs a ready-to-submit form. Live tool fills the form; the snapshot shows the answer matrix for the trickiest fields.
LLC, sole prop, partnership, or corp. Most US LLCs answer 'Limited Liability Company' on line 9a and check the box for the appropriate member count.
Must be a natural person with SSN, ITIN, or (for some non-resident scenarios) just a passport identifier when filing by fax. Cannot be an entity in most cases.
US-resident with SSN: online (instant). Non-resident or entity without SSN: by fax to the IRS (5-7 days).
Pre-filled SS-4 ready to sign and submit. Anonymousllc.co handles the actual submission as a $99 service if you'd rather not.

| Field | SMLLC, US-resident | SMLLC, non-resident | Multi-member LLC |
|---|---|---|---|
| Line 8a (LLC?) | Yes | Yes | Yes |
| Line 8b (members) | 1 | 1 | 2+ |
| Line 8c (US-organized?) | Yes | Yes | Yes |
| Line 9a (entity) | Single-Member LLC (often blank, see instructions) | Single-Member LLC | Partnership (default) or Corporation (if elected) |
| Line 7b (responsible party ID) | SSN | ITIN or 'Foreign' | SSN/ITIN of one member |
| Filing channel | Online (instant) | Fax SS-4 to IRS Cincinnati (5-7 days) | Online if responsible party has SSN |
| Third-party designee | Optional | Recommended — Anonymousllc.co files for you | Optional |
The most common rejection causes: (a) responsible party field claims 'N/A' instead of writing 'Foreign' when ITIN not yet issued, (b) member count mismatch between Line 8b and Line 9a, (c) checking the wrong box for tax classification on Line 9a. Anonymousllc.co's $99 EIN service handles all three correctly.
Non-resident founders without SSN file Form SS-4 by fax (not online). The responsible party field accepts 'Foreign' or an ITIN if already issued. IRS Cincinnati processes the fax within 5-7 business days. The CP-575 EIN confirmation letter is sent by mail (or by fax-back if requested).
The responsible party is the person who 'controls, manages, or directs the entity'. Must be a natural person, not an entity. For SMLLC: the sole member. For MMLLC: the manager or managing member. Must use the person's true legal name and address — Anonymousllc.co's address can be a mailing address but not the responsible party identifier.
Wrong box on Line 9a (claiming corporation when really default LLC). Member count mismatch. Missing responsible party identifier. Stale or incorrect mailing address. Incorrect 'reason for applying' choice. Each rejection adds 4-6 weeks to the timeline.
