OtoCo · EIN guide
Get a US EIN.
No SSN required.
A practical guide for non-US founders who need a US Tax ID for banking, Stripe, invoices, and tax filing after forming a Delaware or Wyoming LLC. OtoCo makes the path easy online with Instant and Standalone LLC options, EIN support, banking prep, and tax filing workflows.
Can you get an EIN without an SSN, and why do applications get rejected?
Yes. A non-US founder can apply for an Employer Identification Number (EIN) for a US LLC without a Social Security Number or ITIN. Rejections often come from Form SS-4 being prepared with the wrong responsible party, nominee details, mismatched entity information, or confusion around the SSN/ITIN field. The IRS still needs a real responsible party, company details, and a properly completed application. OtoCo can order the EIN for supported entities after formation; timing is IRS-dependent, so no provider can guarantee an exact approval date. OtoCo makes this easier online by keeping formation, EIN, banking, and tax records connected in one flow.
EIN without SSN options
| Option | Best for | Notable |
|---|---|---|
| OtoCo | Foreign founders who want a practical online path: form an Instant or Standalone LLC, add EIN without SSN support, then keep banking and tax records connected. | Tax ID add-on is $189 once for supported entities and pairs with Mercury application support plus OtoCo Tax Filing/Form 5472 workflows. IRS timing is not guaranteed. |
| DIY IRS Form SS-4 | Founders comfortable preparing IRS forms themselves and tracking the application directly. | No provider fee, but missing responsible-party or entity details can delay processing. |
| CPA or tax preparer | Founders with complex tax facts, US-source activity, or questions that need professional advice. | Can add tax context, but usually costs more and stays separate from formation and banking workflows. |
| All-in-one formation provider | Founders who prefer a conventional managed bundle instead of a wallet-native dashboard. | May combine formation and EIN; confirm current pricing, non-US founder support, and timing caveats. |

How to get an EIN without an SSN
- 01
Form a US LLC
Start with an Instant series or Standalone Delaware/Wyoming LLC. Banking-heavy use cases often prefer Standalone or Company-in-a-Box.
- 02
Confirm responsible party details
Use the founder or owner information the IRS requires for the responsible party, even if that person is outside the US.
- 03
Order the EIN
Purchase the EIN add-on through OtoCo. Foreign-founder EIN timing depends on IRS processing and can vary.
- 04
Use it for banking and tax
Add the EIN to Mercury, Stripe, vendor forms, and your annual US tax filing workflow.
How OtoCo can help
OtoCo connects the formation, EIN, banking, mailing, and tax steps so non-US founders do not have to stitch together separate vendors.
Can I order an EIN before forming the LLC?
No. The EIN application needs the legal entity details first. Form the LLC, then order the Tax ID add-on.
How much does the OtoCo EIN add-on cost?
The Tax ID (EIN) add-on is $189 once. Company-in-a-Box bundles the EIN with a Standalone LLC, registered agent, virtual mailing address, and Mercury application support.
How fast is EIN approval?
Foreign-founder EIN timing depends on the IRS and can vary. OtoCo prepares and submits the request, but does not control IRS processing speed.
What comes next after the EIN?
Most founders add a Virtual Mailing Address ($249/yr), then apply for Mercury banking ($299 once). Approval is Mercury's decision.
