What changed?
Sovereign immunity from direct tax operates through an uncodified framework and HMRC administrative practice.
Proposed statutory sovereign tax status from 1 January 2029 would bring specified property returns and trading income into tax, alongside defined exemptions and REIT arrangements.
Practical consequence: Sovereign investors should map direct property holdings, investment offices and fund structures before assessing the proposed treatment.
What happened?
HM Treasury opened a consultation on 28 October 2026 proposing a statutory framework for taxing foreign sovereign investors. The intended commencement is 1 January 2029. This is a policy proposal, not an enacted change to current liabilities.
Key details
The consultation would bring UK land income, gains on direct UK land holdings and certain property-rich vehicles, and UK trading income into scope, subject to specified exemptions. UK-source interest would remain exempt. Qualifying state-operated overseas pension funds would receive a gains exemption; qualifying UK investment-management offices would also benefit from an exemption.
The bespoke REIT proposal would permit sovereign investors to control or wholly own a UK REIT through a UK company, with 15% treatment for property income distributions. That rate should not be read as a general tax rate on every sovereign property investment.
Who is affected?
Foreign states, qualifying wholly state-owned entities, sovereign wealth funds, central banks and other eligible sovereign bodies should examine the proposed definitions. HM Treasury notes that UK companies already subject to ordinary corporation tax would remain within that framework.
