This service is built for these situations
Just formed your Delaware LLC
Certificate of Formation issued — the EIN is your next step.
Venture-track founder
Investors often prefer Delaware. We'll prepare your EIN to support that path.
Multi-member structure
Multiple non-U.S. owners filing as a partnership — we know this configuration well.
Formed it yourself or with a registered agent
Your formation service didn't include the EIN. We pick up from there.
Sole owner from abroad
Single-member Delaware LLC with a foreign owner — disregarded entity classification handled.
Previous filing stuck
Your EIN never arrived? We'll diagnose and either follow up or refile.
Getting an EIN as a non-U.S. founder is full of small traps
The IRS process wasn't designed with international applicants in mind. Most rejections and multi-month delays come from a handful of avoidable mistakes.
Common pitfalls
What usually goes wrong when filing alone
- Delaware Certificate of Formation uses specific naming conventions — your SS-4 must match exactly.
- Multi-member LLCs accidentally checked as corporations on line 9a cause IRS confusion.
- Delaware’s annual LLC tax ($400, due June 1) often surprises founders after the EIN arrives.
- Formation packages without an EIN leave you to file the SS-4 yourself — and bank applications stall until you do.
Our approach
How we prevent each of those problems
- Certificate of Formation cross-checked against the draft SS-4 before submission.
- Correct entity classification for single-member vs. multi-member Delaware LLCs.
- Delaware’s annual LLC tax explained at EIN time so it doesn't catch you by surprise.
- We pick up straight after formation, whichever service you used.
What we actually do for you
Delaware-specific review
We check your Certificate of Formation, member list, and operating agreement (if available) before drafting the SS-4.

How the IRS accepts applications from outside the U.S.
Applicants whose business is based outside the U.S. can’t use the IRS online tool. These are the three channels the IRS lists for them. You can use any of them yourself — the EIN is free.
| Method | Where | When | IRS-stated timing |
|---|---|---|---|
| Phone | +1 267-941-1099 (not toll-free) | Monday–Friday, 6:00 a.m.–11:00 p.m. Eastern | EIN issued during the call if the application is complete |
| Fax | +1 304-707-9471 from outside the U.S. · 855-215-1627 from within the U.S. | Any time | Generally within 4 business days (IRS Fax-TIN target) |
| Internal Revenue Service, Attn: EIN International Operation, Cincinnati, OH 45999 | — | Approximately 4 weeks |
- Line 7b without an SSN or ITIN. Enter “foreign” or N/A if the responsible party doesn’t have, and is ineligible to obtain, an SSN or ITIN.
- Daily limit. The IRS issues only one EIN per responsible party per day, across all application methods. Don’t send duplicate applications while you wait.
- Form the LLC first. An LLC or corporation should be formed with its state before applying, or the EIN application may be delayed.
IRS timings are the IRS’s own targets. In practice, fax and mail applications from outside the U.S. often take longer — and an application with an error may get no reply at all, which is the problem our review is designed to prevent.

Common questions from non-U.S. applicants
If your question isn't here, contact us — we'll answer honestly, even if the answer is 'this isn't a fit for our service.'
Should I form in Delaware if I'm a non-U.S. solo founder?
Delaware is excellent for venture-track or multi-member businesses, but if you're a solo founder running an e-commerce or SaaS business, Wyoming may serve you better (lower annual fees, no $400 annual LLC tax). We can help with either — but the decision is yours.
Does Delaware charge anything beyond formation fees?
Yes — Delaware LLCs pay a $400 annual tax, due on or before June 1 for the previous year. Paying late adds a $200 penalty plus 1.5% interest a month (Delaware Division of Corporations). We'll mention this when your EIN issues so you can budget for it.
I used Stripe Atlas — do I still need this service?
Usually not: Stripe Atlas applies for the EIN as part of its package, including for founders without an SSN, though it can take several weeks. We help Atlas customers when the EIN letter is lost or a name mismatch needs fixing.
How fast can I get an EIN for a Delaware LLC?
The IRS process is the same for every state. With our IRS status follow-up, most clients receive their EIN within 1–2 weeks. A same-day EIN is only possible through the IRS online tool (which needs an SSN or ITIN and a U.S.-based business) or the IRS international phone line.

The IRS determines its own processing times, which may vary depending on application volume. Faxed applications requiring a response by mail can take 1–3 months to process. We simplify the process by following up with the IRS on your behalf and keeping you informed of your application status. Once your EIN is assigned, we notify you promptly. While processing times cannot be guaranteed, we strive to make the experience as smooth and straightforward as possible. All prices are listed in USD with no hidden fees, and payments can be made securely through PayPal using supported international payment methods.
