Tax & Compliance · United States

US tax filing done right — no $25,000 surprises.

Foreign-owned US LLCs have strict annual filing duties that most owners don't know about. We handle Form 5472, the pro-forma 1120, and sales tax so your company stays penalty-free.

Why it matters

The filing most LLC owners don't know they owe.

A single-member foreign-owned US LLC is required to file Form 5472 with a pro-forma 1120 every single year — even if it made zero US income. The penalty for missing it starts at $25,000, and many owners only discover this after it's too late.

We take that risk off your plate. We prepare and file your required forms on time, advise on 1040-NR and sales tax where relevant, and track every deadline so your company stays clean and compliant.

Questions

US Tax Filing — answered.

What happens if I don't file Form 5472?

The penalty for failing to file Form 5472 starts at $25,000 per year and can increase. It applies even if your LLC had no US income, which is why timely filing is essential.

Do I owe US tax on non-US income?

A properly structured single-member foreign-owned LLC generally isn't taxed on non-US-sourced income, but the filing obligation still applies. We confirm your specific situation.

When are US filings due?

Federal deadlines fall in the spring, with extensions available. We track your exact dates and can file extensions when needed.

Do I need to collect US sales tax?

It depends on where you have nexus (physical or economic presence). We review your activity and advise where registration and collection are required.

Can you file for a company you didn't form?

Yes. We can take over annual filing for an existing US LLC formed anywhere, after a quick record review.
