Form 5472 for Foreign-Owned Startups: The 25% Test and the $25,000 Penalty

Who Must File

  • A US corporation that is 25% or more foreign-owned: at least one foreign person holding 25% of vote or value, directly or indirectly, at any time during the tax year. Five unrelated foreign angels at 6% each do not trigger it.
  • A foreign-owned US disregarded entity: a single-member LLC wholly owned by a foreign person is treated as a corporation for this one purpose. This category generates the most startup casualties.
  • A foreign corporation engaged in a US trade or business, mainly relevant for foreign parents operating directly in the US.
  • Rerun the test every year: a foreign fund taking 28% in your Series A, or a co-founder's residency change, can pull you into the regime after a clean start.
