A Romanian developer publishing apps on the App Store and Google Play hits the U.S. tax system the first time Apple or Google issues a payout. Both platforms require tax forms from non-U.S. publishers (W-8BEN-E for entities, W-8BEN for individuals), and how you fill them out determines whether 30% of every dollar is withheld at the U.S. border or 0% under the U.S.-Romania tax treaty. The U.S. LLC is the structure that makes the treaty position cleanly defensible — and gives you a U.S. business bank account for the payouts to land in.
This guide covers the practical setup for Romanian app developers: which LLC structure, what to file, how the EIN and W-8BEN-E coordinate, and what BOI and 5472 actually mean.
Why an LLC at All
A Romanian sole proprietor can publish apps without forming a U.S. entity. Apple and Google will accept Romanian tax IDs on Form W-8BEN. Under the U.S.-Romania tax treaty, royalties on software and copyrighted works are generally exempt from U.S. withholding (the treaty's royalty article). So technically, a Romanian individual can collect App Store and Play Store revenue with 0% U.S. withholding without ever forming a U.S. LLC.
What the LLC adds:
- A U.S. business bank account at Mercury, Relay, or Brex, which pays out to Romania faster and cheaper than direct international wires from Apple/Google
- Limited liability for app-related claims (privacy, IP, contract disputes from U.S. counterparties)
- A cleaner W-8BEN-E with a U.S. EIN that platforms recognize immediately rather than processing as an unusual non-resident individual file
- Easier ad-network onboarding (AdMob, AppLovin, Unity Ads) which often expects a corporate entity
- A clean separation between personal Romanian income and U.S.-routed app income for both Romanian and U.S. compliance
For developers earning more than a few thousand dollars per month from the U.S. market, the LLC pays for itself in reduced friction.
Which State to File In
Three serious options for Romanian-owned single-member LLCs:
Wyoming. Default recommendation. Formation around $100, annual report around $60, members not in public filings, no state income tax. Wyoming is the strongest combination of cost, privacy, and U.S. bank acceptance.
Delaware. The right answer if you plan to raise U.S. venture capital for your app studio. Otherwise, the annual franchise tax ($300+) and slightly higher friction don't justify Delaware over Wyoming for a non-resident app developer.
New Mexico. Cheapest ($50 formation, no annual report) and member privacy comparable to Wyoming. Some U.S. fintech banks prefer Wyoming entities at onboarding for reasons that are not always principled, but for many Romanian app developers New Mexico works fine.
Avoid California, New York, and Florida unless your operations specifically require nexus there. Franchise taxes and reporting load are not worth it for a non-resident.
The Filings That Matter
- Articles of Organization — filed with the state's Secretary of State. Wyoming processes in 1 to 5 business days standard, same-day if you pay for expedited.
- Registered agent — required in the state of formation. Commercial registered agent services run $50 to $150 per year.
- Operating Agreement — not filed publicly but functionally required. Banks, contract counterparties, and Apple/Google's enterprise compliance reviewers expect to see one. Even single-member LLCs need one.
- EIN via Form SS-4 — filed with the IRS after the LLC is formed. For non-residents without an SSN, this is fax or mail. Typical IRS processing through CAA channels is days; direct mail is 3 to 5 weeks.
- Form W-8BEN-E — submitted to Apple and Google. Requires the EIN, the LLC's address, and a treaty position claim citing the relevant article of the U.S.-Romania treaty.
- Beneficial Ownership Information (BOI) — filed with FinCEN under the Corporate Transparency Act. Required for most LLCs. Penalties for non-filing escalate quickly. itin.net files this as part of formation.
- Form 5472 + pro forma 1120 — annual IRS filing required for foreign-owned single-member U.S. LLCs, regardless of whether the LLC owes U.S. tax. Penalty for failure to file starts at $25,000. This is the filing most Romanian app developers miss.
The U.S.-Romania Tax Treaty Position
The U.S.-Romania income tax treaty (in force since 1976) provides that:
- Royalties on copyrighted works (which generally includes mobile app revenue from the App Store and Play Store, where Apple and Google characterize the payment as a royalty) are taxable only in the country of residence of the recipient. For a Romanian individual or Romanian-owned LLC properly elected as a pass-through, this means 0% U.S. withholding.
- Business profits are taxable only in the U.S. if there is a U.S. permanent establishment. A non-resident-owned LLC operating an app business without a U.S. office or employees generally does not have a permanent establishment.
The W-8BEN-E (for the LLC) needs to:
- Identify the LLC and its EIN
- Identify the beneficial owner (you, as the Romanian member)
- Identify Romania as the country of residence
- Cite the treaty article that supports the royalty exemption
- Be signed by the beneficial owner
A correctly executed W-8BEN-E pushes Apple and Google withholding to 0% on royalty payments. An incomplete or missing form results in default 30% withholding, which is essentially a permanent loss because reclaiming withheld amounts is procedurally difficult.
Banking and Payouts
With the LLC and EIN in hand, opening a U.S. business account at Mercury or Relay is straightforward:
- LLC's Articles of Organization
- Operating Agreement
- EIN confirmation letter (CP-575)
- Passport of the beneficial owner
- A Romanian proof of address (utility bill, lease, or bank statement)
Once the account is open, update payout details with Apple App Store Connect and Google Play Console to route payments to the U.S. account. Most Romanian developers see USD payouts arrive 2 to 3 business days faster than the previous Romanian routing.
What Romanian Developers Get Wrong
- Defaulting to Delaware because "everyone uses Delaware." Delaware makes sense for venture-backed companies. For an app developer, Wyoming is almost always the better answer.
- Forming the LLC and skipping Form 5472. The IRS does not send reminders. The $25,000 penalty arrives by mail one to three years later.
- Filing W-8BEN-E with the wrong treaty article cited, or no article cited at all. Apple and Google's withholding agents reject the form and default to 30% withholding. Fix the W-8BEN-E before payouts begin, not after.
- Skipping the Operating Agreement. Banks ask. Apple's enterprise compliance reviewers ask. Investors will ask. Forming the LLC without one creates downstream friction at every step.
- Forgetting BOI under the Corporate Transparency Act. This filing was new for LLCs in 2024 and many founders treat it as optional. It is not. Penalties escalate.
Cost and Timeline
For a Romanian developer starting from zero:
- LLC formation in Wyoming: 1 to 5 business days
- EIN issuance: days through a CAA, 3 to 5 weeks via direct mail
- Operating Agreement drafted: part of formation packages
- BOI filed: during or immediately after formation
- U.S. business bank account opened: 1 to 3 business days at Mercury/Relay
- W-8BEN-E delivered to Apple and Google: same day, takes effect within 1 to 2 days
- End-to-end: typically 5 to 10 business days through itin.net
The itin.net non-resident LLC bundle (LLC + EIN + Operating Agreement) is $497. Standard LLC-only is $297. Annual costs after the first year are state fees plus registered agent plus an accountant for Form 5472 (the 5472 is a $200 to $500 filing depending on complexity).
Pro Tips Specific to App Developers
- Form the LLC and EIN before Apple/Google ask you for tax forms. Once they request the form, payouts are paused until it is provided. Have the documents ready.
- Use the same business name on the LLC, the App Store developer account, and the Play Store developer account. Mismatches trigger compliance reviews and delay payouts.
- Keep a separate Operating Agreement clause for IP ownership. Apps you develop personally before forming the LLC are not automatically owned by the LLC. Assign them to the LLC explicitly.
- Set a calendar reminder for April 15 each year for Form 5472. Even if the LLC had no U.S. income tax, the form is mandatory.
- If you co-found with another developer, structure as multi-member from day one. Converting single-member to multi-member later requires amending the LLC, restating the Operating Agreement, and re-electing tax treatment.
Frequently Asked Questions
Do I need an ITIN to form a U.S. LLC from Romania?
No. The LLC needs an EIN, not an ITIN. An ITIN is a personal taxpayer ID; the LLC is an entity with its own EIN. Apply for an ITIN only if you personally have a U.S. tax filing obligation in your own name.
How does the U.S.-Romania tax treaty affect my LLC?
The treaty assigns taxing rights between the U.S. and Romania. For app royalties paid by U.S. platforms (Apple, Google) to a Romanian beneficial owner of a U.S. LLC properly elected as a pass-through, the treaty's royalty article generally exempts the payments from U.S. withholding. The position is claimed on Form W-8BEN-E.
Can I use my Romanian bank account with my U.S. LLC?
You can, but most Romanian developers find that a U.S. business account simplifies App Store and Play Store payouts, vendor payments, and U.S. tax filings. Mercury and Relay are the standard remote-friendly options.
What happens if I don't file the BOI report?
FinCEN penalties for non-filing escalate. The CTA includes civil penalties (per-day) and, for willful violations, criminal penalties. Treat BOI as mandatory.
How do Apple and Google know my LLC is legitimate for payments?
They verify the LLC against the EIN you provide on Form W-8BEN-E. The CP-575 letter from the IRS confirms the EIN. With both in place, App Store Connect and Play Console process payouts under the LLC's name.
Can I manage my U.S. LLC from Romania without visiting the U.S.?
Yes. LLC formation, EIN application, banking, App Store onboarding, and ongoing compliance can all be handled remotely. No U.S. visit is required.
