For foreign-owned US single-member LLCs
Delaware LLC Form 5472 Filing Guide
Delaware is the #2 most popular state for foreign-owned US LLCs after Wyoming. Stripe Atlas defaults to Delaware, so a large share of foreign-founder LLCs are Delaware entities. If you formed a Delaware LLC and you're not a US person, you must file IRS Form 5472 with pro forma Form 1120 every year — even if your LLC had zero revenue. This is the full Delaware-specific filing playbook including the federal Form 5472, the $300 Delaware franchise tax, and the differences from Wyoming.

Frequently asked questions
- Does Delaware notify the IRS about my LLC?
- Delaware reports the LLC at formation when you got your EIN — that linked Delaware's entity number to your IRS records. Annual federal filings (including Form 5472) are your responsibility going forward; Delaware doesn't track them.
- Is the Delaware franchise tax separate from Form 5472?
- Yes. The $300 Delaware franchise tax is paid to the Delaware Division of Corporations (state level). Form 5472 is filed with the IRS Ogden PIN Unit (federal level). They're completely separate; missing one doesn't affect the other.
- Can I move my LLC from Delaware to Wyoming to avoid the franchise tax?
- Yes, via domestication. Costs ~$200-$400 and takes 2-4 weeks. But Form 5472 obligation is identical in both states — domestication only saves state fees, not the federal filing requirement.
- I used Stripe Atlas — doesn't that include Form 5472?
- No. Stripe Atlas is a formation product. Their docs explicitly state they don't handle annual federal tax filings including Form 5472. Their optional ongoing services may include some help, but the standard Atlas formation product is one-time.
- What if I miss the Delaware franchise tax?
- Delaware imposes a $200 late penalty plus 1.5% monthly interest. After several missed years, Delaware can administratively dissolve your LLC. To reinstate you'd pay all back fees plus a reinstatement charge. Different from the IRS Form 5472 penalty, but still costly.
- Do I need a Delaware-based CPA?
- No. Form 5472 is a federal filing — any US CPA familiar with international information returns can prepare it. Most don't. Our flat-fee service is built specifically for this filing and reviewed by an accountant on our team.
- Does Delaware have its own equivalent of Form 5472?
- No. Delaware doesn't impose a state-level analog of Form 5472. Your state filings are just the $300 franchise tax and any sales tax if you cross nexus thresholds.
- My Delaware LLC made no money in year 1 — do I still file Form 5472?
- Yes, almost certainly. If you had even one capital contribution (e.g. wiring money to fund the Mercury account or pay the Stripe Atlas fee), that's a reportable transaction. Most Delaware LLCs file every year regardless of revenue.
- Can I file Form 5472 before I file the Delaware franchise tax?
- Yes — they're independent. Form 5472 federal deadline is April 15; Delaware franchise tax deadline is June 1. File each on its own timeline.
- What's the cheapest year-1 federal compliance for a Stripe Atlas Delaware LLC?
- Federal: Standard $199 (our service, fax included). Add the $300 Delaware franchise tax = $499 total annual compliance. Add Stripe Atlas's one-time $500 formation cost (year 1 only) for full year-1 picture.

Wyoming LLC Form 5472 Filing Guide
Wyoming is the most popular state for foreign-owned US LLCs because of its low fees, no state income tax, strong privacy laws, and cheap registered agent ecosystem. But Wyoming residency doesn't exempt you from federal filings — every foreign-owned Wyoming LLC must file IRS Form 5472 with pro forma Form 1120 by April 15 each year, with a $25,000 penalty if missed. This is the complete federal + Wyoming-state filing playbook for foreign owners.
Foreign-Owned US LLC Tax Filing Requirements
If you are a non-US person who owns a US single-member LLC, you have specific federal tax filing obligations even if your LLC made zero revenue and owes zero US tax. The main universal requirement is Form 5472 with an attached pro forma Form 1120, due April 15. Beyond that, your state filings, ITIN need, FBAR/FATCA exposure, and sales tax obligations depend on your specific facts. This is the complete map.
How to File IRS Form 5472
Foreign-owned US single-member LLCs must file Form 5472 with an attached pro forma Form 1120 by April 15 each year.

Below is the full step-by-step process, broken down into every form, field, and decision you'll face — or skip the work entirely and use our accountant-reviewed 15-minute online filer from $199.
Stripe Atlas LLC owners — Form 5472 is on you, not Stripe
Stripe Atlas makes US LLC formation effortless for foreign founders — Delaware LLC + EIN + Mercury bank account in days. What Stripe Atlas explicitly does NOT handle is the annual IRS filing your LLC owes every year: Form 5472 + pro forma Form 1120. Skip it and the IRS charges $25,000 per year, per form. This is the complete Stripe Atlas + Form 5472 playbook — including the typical year-2 surprise, the Delaware franchise tax, and how to catch up if you've missed prior years.
