Form 5472 for Foreign-Owned US LLCs: The $25,000 Penalty Trap That Catches Single-Member Disregarded Entities Off Guard
Foreign owners of US single-member LLCs must file Form 5472 by April 15, 2026, even with zero revenue. A capital contribution as small as $1 triggers the requirement, and a missed filing carries a $25,000 minimum penalty plus uncapped $25,000 continuation fees every 30 days after IRS notice.
