Who Must File
A US LLC wholly owned by one foreign person, or a US corporation that is at least 25% foreign-owned.
- Single-member LLC owned by a non-US person
- No US income needed to trigger it
- Applies from the year you form
Every foreign-owned single-member US LLC must file Form 5472 with a pro forma Form 1120 each year, even when it owes no US tax. Our in-house CPAs prepare and file it for you, from $999 a year.
The Rule
Three things decide your Form 5472 filing. Most non-resident LLC owners meet all three.
A US LLC wholly owned by one foreign person, or a US corporation that is at least 25% foreign-owned.
Money and value that move between the LLC and its foreign owner or related parties during the year.
Due by the 15th day of the 4th month after year-end, which is April 15 for calendar-year LLCs.
Owe zero US tax? You still have to file.
Your Options
Form 5472 looks short. The pro forma 1120 around it, and getting every reportable transaction right, is where owners slip.
How It Works
You send the records. We handle the IRS.
Bank statements and owner transactions for the year, gathered with you in the GenZone platform.
Our CPAs classify every reportable transaction and build the pro forma Form 1120 for your LLC.
We walk you through every number before anything goes to the IRS.
Submitted before the deadline, with the confirmation saved in your dashboard.
Included in our Advanced and Done-for-You plans, from $999 a year.
Is This You?
If you are a non-US person who owns a US LLC, this applies to you.
Formed this year and facing your first filing.
Missed a year or more. We review what is outstanding and catch it up.
Stripe, Amazon or Shopify payouts with many owner transfers to track.
If you are a US citizen or resident, this filing works differently for your LLC.

Avoid These
Each of these can turn a zero-tax LLC into a $25,000 problem.
Filing is required even with zero revenue. Paying the LLC's formation costs is itself a reportable transaction.
Most foreign-owned LLCs owe no US income tax, but Form 5472 and the pro forma 1120 are still due every year.
A foreign-owned LLC's pro forma 1120 with Form 5472 is filed by fax or mail, not through standard e-file.
It is $25,000 per form, per year, with more added if the failure continues after the IRS writes to you.
