IRS Form 5472 & 1120 Filing for Foreign-Owned U.S. Companies

Who must file?

Any non-U.S. resident who owns a U.S. LLC (Delaware, Wyoming, or any state) must file Form 5472 + pro forma 1120 every year — even with $0 in revenue. The IRS penalty for a missing or incorrect filing is $25,000 per form, per year.

  • Deadline: April 15 each year (October 15 with extension)
  • Applies to single-member LLCs with a U.S. EIN and a foreign owner
  • Required even if the LLC had no income or activity
