Which Form 5472 exceptions don't apply to my foreign-owned single-member LLC?

Some practitioners assume that if a U.S. person related to your LLC is filing Form 5471 (with Schedule M) for the foreign related corporation, your Form 5472 obligation is satisfied. The current Form 5472 instructions explicitly state that this exception does not apply to foreign-owned U.S. disregarded entities. If your filing obligation exists because you are a foreign-owned domestic disregarded entity under Treas. Reg. 301.7701-2(c)(2)(vi), someone else's Form 5471 filing does nothing for you.

Two more frequently-mentioned exceptions are also explicitly unavailable to foreign-owned U.S. disregarded entities: the Foreign Sales Corporation exception under section 6038A, and the exception for related-party transactions that have no U.S. tax effect (the so-called 'foreign-to-foreign with no U.S. tax effect' rule). The Form 5472 instructions name both directly and say they do not apply to foreign-owned U.S. DEs.

Treas. Reg. 1.6038A-1(h) and (i) provide reduced recordkeeping and agent-authorization relief for 'small corporations' (annual gross receipts under $10 million) and for low-volume related-party filers (de-minimis safe harbor). These reliefs are unavailable to entities that are reporting corporations solely because they are foreign-owned domestic disregarded entities under 301.7701-2(c)(2)(vi). In other words, even a $20,000-annual-revenue foreign-owned single-member LLC cannot use the small-corp relief on the Form 5472 framework.

The single exception that does apply to a foreign-owned U.S. disregarded entity is the 'no reportable transactions during the tax year' exception. If the entity had zero qualifying transactions (Parts IV and V), there is no Form 5472 obligation for that year. But the trap is that Part V captures more than most filers realize — owner capital contributions, distributions, entity formation, dissolution, and acquisition or disposition of the entity all count. Most supposedly dormant foreign-owned LLCs still have at least one Part V transaction, which means most still owe a Form 5472.
