Can I file Form 8858 instead of Form 5471 as the sole owner of my foreign LLC?
Yes, if your foreign LLC is classified as a foreign disregarded entity (FDE) under U.S. tax rules, you file Form 8858 instead of Form 5471. The deciding factor is entity classification, not the name of the form used by the foreign country.
How to tell which form applies:
| Entity type | U.S. tax classification | Form filed |
| Foreign LLC, single owner, default | Foreign disregarded entity | Form 8858 |
| Foreign LLC, elected C-corp (Form 8832) | Foreign corporation | Form 5471 |
| Foreign LLC, multi-member, default | Foreign partnership | Form 8865 |
| Foreign LLC on “per se” list (e.g. UK Ltd, German GmbH) | Corporation always | Form 5471 |
Entities on the Treasury “per se” corporate list cannot elect to be disregarded. This list includes UK Limited, German GmbH (AG is always a corporate form), French SA, Spanish SA, and Canadian corporations (but not Canadian ULCs, which default to disregarded). A UK LLP can elect to be disregarded for a single member.
Form 8858 is generally simpler than Form 5471:
- Shorter schedule structure (3 to 4 pages vs 20+)
- No Subpart F or GILTI inclusion (since the entity is transparent)
- Income and expenses flow directly to your Schedule C or Schedule E
Late filing on either form triggers a $10,000 penalty per form per year (IRC 6038). Penalties stack quickly for multi-year delinquency.
