Information returns for US persons owning or operating through foreign entities — UK LLPs, partnerships, and Ltd companies.
Owning even a minority stake in a foreign entity puts you in scope for some of the IRS's most paperwork-heavy returns. Form 5471 (foreign corporations), 8865 (foreign partnerships), 8858 (disregarded entities) and the GILTI / Subpart F regimes are designed to make sure US persons can't park income in non-US structures. Most of our clients didn't realise their UK LLP membership or family-business shareholding triggered any of this — and the penalties for missing the forms are automatic.
Each one is a separate service with its own page — click Learn more on any block below to see the full scope, deliverables, and pricing notes.
