UK investors in US LLCs: Are you being taxed twice without realising?
For many years, UK investors holding interests in US LLCs have faced a frustrating and often costly reality: being taxed on the same income twice. The reason? A fundamental mismatch between UK and US tax systems.
In the US, LLCs are typically treated as transparent, meaning profits are taxed directly on the individual as they arise. In the UK, those same LLCs are usually treated as ‘opaque’, with tax only applied when profits are distributed.
This disconnect can leave UK-resident individuals exposed to inefficient outcomes, lost tax credits, and unexpected liabilities – particularly where US taxes aren’t fully creditable in the UK.
A possible solution for UK investors in US LLCs
HMRC has now launched a consultation that could finally address this issue. The proposed changes suggest that certain US LLCs may be treated as transparent to individual owners for UK tax purposes, aligning the UK more closely with US treatment. If implemented, this could:
- reduce or eliminate double taxation;
- improve cash flow for investors;
- unlock previously unattractive US investment structures.
However, the rules are likely to apply only to specific entities and individuals. Key questions remain around eligibility, anti-hybrid rules, and whether an election will be required. Also, timing is uncertain, with potential changes not expected before April 2027.
What this means for you
If you’re a UK resident with US investments – or considering them – this is a critical development.
The window between now and implementation creates an opportunity to:
- review existing LLC structures;
- assess current tax leakage and inefficiencies;
- position yourself ahead of potential rule changes.
Don’t wait for the rules to change
