Form 5472 for Nigerian-Owned US LLCs (2026)

Quick answer

If you're a Nigerian founder with a US single-member LLC, you generally must file Form 5472 + a pro-forma 1120 every year, even at $0 tax. Failing to file Form 5472 when due and in the manner prescribed carries a $25,000 penalty.[1] Note: there is no US–Nigeria tax treaty, so there's no treaty relief, and how double taxation is handled depends on US and Nigerian (FIRS) rules separately. Confirm with advisors. (US filing: HIGH. Nigeria side: NEEDS LOCAL EXPERT REVIEW.)

Key facts

  • A foreign-owned U.S. disregarded entity has no income tax return filing requirement of its own, but must still file a pro forma Form 1120 with Form 5472 attached by that Form 1120's due date.[2]
  • Failing to file Form 5472 when due and in the manner prescribed carries a $25,000 penalty.[1]
  • No US–Nigeria tax treaty. HIGH, IRS treaty list
  • FIRS treatment of foreign income with no treaty. Confirm with an advisor. NEEDS LOCAL EXPERT REVIEW

What this means for you (Nigeria)

Budget for the annual 5472 as a fixed cost, separate from any tax. Because there's no treaty, ask a cross-border advisor how your foreign income is handled by FIRS and how to avoid being taxed twice without treaty relief.
