What are reverse hybrids & LLCs in UK tax law?
Reverse hybrids are overseas entities treated differently both in the UK and abroad, often leading to double taxation. One example is a US LLC where the UK treats it as a company, but the US treats it as transparent. This mismatch can lead to high effective tax rates.(gov.uk)
What’s changing: consultations and proposals
- On 10 June 2026, the government published a consultation on UK resident individual members of LLCs & other reverse hybrids, aiming to remove double taxation and align the tax treatment to avoid unfair burdens.(gov.uk)
- Draft legislation was included in the Tax Update 2026 package titled Capital Gains Tax relief on gifts of business assets; while not specific to hybrid mismatches, it reflects broader efforts to correct long-standing distortions.(gov.uk)
Practical implications for structuring:
- If you have interests in US LLCs, or operate through entities overseas that the UK treats as reverse hybrids, you may face excessive tax burdens unless rules are updated.
- The consultation may lead to new rules clarifying how distributions, profits, and capital gains are taxed, potentially altering both compliance and planning options for cross-border structures.
What you can do now:
- Review existing entity structures. Are you using an LLC or reverse hybrid? Consult tax advisors familiar with UK tax and international double tax treaties.
- Assess whether existing cross-border payments/dispositions could trigger double taxation under current rules.
- Monitor the policy process: the feedback period, draft legislation, and eventual enactment may allow stakeholders to input their experiences.
Example scenario:
Maria, a UK resident, invests in a US LLC carrying on business. Under US law, she looks through to profits; under UK law, the LLC is treated as a company with corporation tax, and further tax on distributions. The proposed consultation aims to reduce the extra layers or future mismatches.
Bottom line: For those using overseas entities or US LLC-style vehicles, the consultation signals potential for reform—this is an area to watch closely, review current structures, and plan ahead for change.
