Services
Every filing a non‑US founder needs, in one place.
Take any of these on their own, or let us hold the whole thing. Either way you get the same updates and the same person answering you.
LLC formation
A clean, correctly structured single or multi‑member LLC in the state that actually suits your business.
- Name availability check
- Articles of organisation filed
- Operating agreement

- US business address
- Digital document pack
EIN & ITIN
Your federal tax ID filed the foreign‑owner way, plus a personal ITIN when your situation requires one.
- EIN obtained without an SSN
- Faster EIN route available
- ITIN application prepared
- Certified document handling
- IRS correspondence managed
- Copies stored for your records
Payment gateways & banking
Application setup and onboarding support for Stripe, PayPal, Wise and Payoneer, using entity details that match your formation documents.

Tax return filing
Federal and state returns prepared and filed, including the forms foreign‑owned LLCs are most often penalised for missing.
- Federal return preparation
- State return where required
- Form 5472 and 1120 where applicable
- Estimated quarterly taxes
- 1:1 consultation
- Extension filing if needed
Annual compliance
One calendar for every deadline your company has, watched by us instead of remembered by you.
- Annual report filing
- Franchise tax where applicable
- Registered agent renewal
- Address renewal
- Deadline reminders in writing
Beneficial ownership (BOI) reporting is not included as standard: under current FinCEN guidance, entities created in the United States are exempt. Where it does apply — for example a foreign‑formed entity registered to do business in the US — we confirm it case by case.
