Form 8858 Filing for Foreign Disregarded Entities

Form 8858 is required from US persons who own foreign disregarded entities (FDEs) — such as certain single-member foreign LLCs that are treated as disregarded for US tax purposes. It's also required when a controlled foreign corporation (CFC) or foreign partnership owns an FDE. The form requires detailed financial information about the entity and the penalty for non-filing is $10,000 per form per year.

When human review matters

ⓘ Default classification rules determine whether a foreign entity is disregarded or classified as a corporation — the entity type and country matter
ⓘ If the entity has more than one owner, it cannot be disregarded and may require Form 8865 or 5471 instead
ⓘ E-Residency Estonia OÜ companies owned by a single US person are a common Form 8858 scenario

REFERENCE/COMMON QUESTIONS

Frequently asked questions about Form 8858 Filing for Foreign Disregarded Entities

What is a foreign disregarded entity?

A foreign disregarded entity (FDE) is a foreign business entity with a single owner that is not treated as a corporation for US tax purposes — it's 'disregarded' as separate from its owner. Single-member LLCs in many countries can qualify as FDEs if the appropriate classification applies.

How is Form 8858 different from Form 5472?

Form 5472 is filed when a US entity (like a US LLC) is owned by a foreign person. Form 8858 is filed when a US person owns a foreign disregarded entity. Both relate to disregarded entities, but in opposite ownership directions.

What is the penalty for not filing Form 8858?

$10,000 per form per year. If not corrected after IRS notice, an additional $10,000 per 30-day period applies. The filing is mandatory even if the entity had no income.
