Background: Reverse Hybrids & Overseas Double Taxation Issues
Some types of investment structures (notably US Limited Liability Companies, LLCs, and other 'reverse hybrids') have been creating situations where profits are taxed more than once—under UK rules and by foreign jurisdictions. The effective rates can reach over 75% in some cases. In June 2026, the government published a consultation to remove this double taxation. (gov.uk)
What the Consultation Proposes
- Changes to the tax treatment of members of US LLCs and similar entities, so that profits now taxed in another jurisdiction aren’t effectively taxed again in the UK.
- Aligning UK rules to international norms for reverse hybrid entities to reduce mismatch and over-taxation.
- As part of the wider “simplification, modernisation and fairness” agenda to foster internationally competitive investment position. (gov.uk)
Potential Structuring Implications
| Scenario | Before Proposed Change | After (if adopted) |
|---|---|---|
| UK individual investor in a US LLC earning profits taxed in US | Income taxed in US and UK under current rules; possibly little or no credit relief for mismatch | Reduced or eliminated double taxation; smoother reliefs; better net returns |
| UK company investing in a reverse hybrid structure | Complexity re distributions and tax treaties, potentially higher tax bills | More predictable tax treatment, lower effective rates, fewer unexpected liabilities |
Actionable Steps Before Changes Become Law
- Review current investment vehicle types (LLCs, trusts, reverse hybrids).
- Where possible, delay non-urgent distributions until clarity (post consultation) if you're likely to benefit from new reliefs.
- Speak to tax adviser about treaty reliefs and whether existing foreign tax paid is being fully credited.
- Consider alternative structures (UK LLPs, UK holding companies) temporarily if double taxation is a serious drag.
Timeline & Outlook
- As of 23 June 2026, the consultation is closed. The government will review responses before drafting any legislation. Timing of enactment is likely 2027 or via Finance Bill 2026-27. Users should plan ahead but expect time for transition. (gov.uk)
Examples
- John, UK resident, invests in a US LLC which distributes profits annually; under new rules he might pay US tax first, then UK with relief reducing his home-jurisdiction tax to match global norms.
- A UK fund using an LLC structure may benefit via treaty relief changes, helping avoid loss through double taxation on foreign income returns.
Concluding Thought: These reforms can materially affect international investment decisions—structural review is warranted now, tailoring for individual circumstances, and with an eye on law changes expected in upcoming Finance Bills.
