US LLC Annual Compliance for UK Founders
HMRC International Manual INTM180030 allows case-by-case transparent treatment of US LLCs after Anson v HMRC [2015] UKSC 44, meaning UK-resident owners report LLC profits as foreign self-employment income via Self Assessment SA100 + SA103 + SA106 in standard practice. Form 5472 plus state filings remain the US-side compliance core; the UK-side layer is substantially lighter than the Indian, Chinese, or Canadian regimes.
A US LLC owned by a non-US resident sits in two compliance regimes simultaneously: the US federal + state filings (Form 5472, BOI, annual report, registered agent renewal) and the home-country reporting layer (FEMA Form A2, SAFE registration, FBAR if a US person, etc.). The compliance calendar and the registered-agent options below cover the US side; the cross-border layer below covers what the home country sees.

United Kingdom cross-border compliance layer
US-side annual compliance for a UK-resident-owned US LLC follows the standard non-US-owner framework. Form 5472 with pro-forma 1120 is due by April 15 (with the June 15 extension available for foreign owners with no US trade or business), with the USD 25,000 per-failure penalty under IRC Section 6038A. State annual report / franchise tax follows the state-specific calendar. CTA BOI reporting is subject to the FinCEN March 2025 interim final rule pause. Registered-agent renewal annual.
The UK-side compliance layer is materially lighter than the Indian, Chinese, Canadian, or Pakistani regimes due to the post-Anson treatment of US LLCs. HMRC International Manual INTM180030 + INTM334000 series allows case-by-case transparent treatment when the LLC operating agreement vests profits directly in members. Where transparent: the UK-resident owner reports LLC profits as foreign self-employment / business income on Self Assessment (SA100 + SA103 Self Employment + SA106 Foreign supplement), due January 31 following the end of the UK tax year (April 6 to April 5). Where opaque: the LLC is treated as a foreign company with separate corporate filings and CFC rules apply under TIOPA 2010 Part 9A. The election between transparent and opaque pivots on the LLC operating agreement and is best confirmed by a UK tax adviser experienced in cross-border structures.
The US-UK Tax Treaty (1975, last amended by 2002 Protocol) Article 26 Exchange of Information + FATCA IGA Model 1 (signed 2012) provide enforcement coordination. HMRC's Worldwide Disclosure Facility and the Requirement to Correct rules under Finance (No. 2) Act 2017 govern late-disclosed foreign income with elevated penalties. National Insurance Contributions (NIC) Class 2/4 may apply where UK self-employment characterisation applies; SA303 self-employment commencement notification is the entry point.
