Sovereign Tax Status: A New Era for Foreign State Investment in the UK?

On 28 October 2026, HM Treasury published a consultation on “Modernising taxation of foreign sovereign investments”. The consultation proposes replacing sovereign entities’ existing broad immunity from direct taxes with a statutory ‘sovereign tax status’ regime from 1 January 2029. Although certain exemptions would remain, the changes could materially affect both directly held property and investments held through funds and other vehicles. This follows an earlier 2022 consultation which was ultimately dropped. 

Current framework

The UK currently provides a broad exemption from direct taxes for foreign sovereign individuals, states and certain connected entities. The exemption is not set out in legislation but rests on principles of international law applied through HMRC’s administrative practice.

Who would qualify for sovereign tax status?

The proposed regime would provide qualifying sovereign entities with specified exemptions from certain taxes but otherwise would generally tax sovereigns in the same way as other non-resident investors. The Government expects the most material change to be the taxation of sovereign investors on returns from directly held UK real estate. However, the implications would likely extend to property held through tax-transparent structures, such as partnerships and Jersey property unit trusts (“JPUTs”), and exempt vehicles such as real estate investment trusts (“REITs”).

The proposed ‘sovereign tax status’ would be available for:

1. foreign sovereign states and their governments, heads of state (when acting in their sovereign capacity), and central banks;
2. wholly state-owned entities, incorporated and resident in the foreign sovereign’s home country;
3. sovereign wealth funds; and 
4. state-operated overseas pension funds. These would form a separate category, and to qualify, a fund would need to be established and operate exclusively (or almost exclusively) to provide or administer retirement benefits for individuals employed in providing government, public or social services to the relevant state. 

Sovereigns would need to make a formal application for the status to HMRC, including those already recognised as sovereigns under the current regime. 

What would be taxed, and what would remain exempt? 

Subject to the proposed exemptions, sovereign investors would become taxable on income from UK land, gains on disposals of directly held UK land and interests in certain UK property-rich vehicles, and UK trading income.

The following would be exempt from tax: 

• UK-source interest income, dividends paid by UK companies;
• profits of UK investment management activities carried on by sovereign investment offices (where the activities are specifically to manage and benefit the portfolio);
• chargeable gains of state-operated overseas pension funds (in line with the UK’s treatment of overseas pension funds and registered pension schemes); and
• UK-situated state property held by a sovereign individual, for inheritance tax purposes.

Implications for REITs and other investment vehicles 

The proposals also include tailored rules for investment vehicles. These would preserve access to a number of existing regimes, but with important qualifications for UK property investments. The most notable are set out below.

Real Estate Investment Trusts 

There are two linked proposals which would be particularly important for sovereign investors with substantial REIT holdings. 

1. Sovereigns would come under the holder of excessive rights rules. Sovereigns would be qualifying institutional investors for REIT purposes. However, the holder of excessive rights (“HoER”) rules (which can impose a tax charge within a REIT where a person holds an interest of 10% or more) would be modified to include sovereigns holding such an interest and prevent them from avoiding the charge under the HoER rules by splitting their holdings between connected entities.
2. Sovereign holding company regime. Sovereigns holding an interest of 10% or more could avoid this charge by incorporating a “qualifying company”. The company must be UK tax resident, wholly owned by a person with sovereign tax status, used only to invest in REITs, and HMRC must be notified that it is being so used. The holding company would pay tax at 15% on gross property income distributions (“PIDs”), with no deductions. Other REIT distributions and gains on REIT shares would remain subject to normal corporation tax rules. 

The proposed regime would therefore allow a sovereign to control or wholly own a UK REIT while accessing a 15% rate on PIDs, comparable to the rate typically available to non-resident investors under UK tax treaties. Although described as optional, the holding company regime may be effectively a commercial requirement for sovereign investors with substantial REIT interests. Without it, a HoER charge within the REIT could make the structure unattractive, particularly where the REIT is co-owned. 

Investment funds and holding companies

Sovereigns would be qualifying institutional investors (“QIIs”) for certain investment regimes, including qualifying asset holding companies, long-term asset funds and the non-resident capital gains rules for collective investment vehicles. This would allow them to continue to wholly own or control investment funds while accessing certain benefits of those regimes. It would also preserve the tax status of such funds where that fund was relying on having QIIs as all or part of its investor base.

Substantial shareholding exemption

Sovereigns would retain QII status for certain substantial shareholding exemption purposes, except for disposals of interests in UK property-rich vehicles. State-operated overseas pension funds would retain QII status for these purposes even on disposals of interests in UK property-rich vehicles.

Transitional relief

Assets not previously subject to tax on gains would be rebased to market value at 1 January 2029, so that only subsequent increases in value would be taxable. Investors should consider what valuation evidence they may need to support that rebasing.

A time-limited stamp duty land tax (“SDLT”) relief is proposed for restructuring existing property holdings. The intended window would run from 2028 until at least 31 December 2030, although the precise dates remain to be settled. The relief would apply only in England and Northern Ireland and would be subject to a proposed three-year change-of-control clawback. Its scope and conditions will be important when assessing restructuring options.

Targeted transitional relief for debt and derivatives, together with the transfer of pre-trading characteristics, is also proposed.

What should sovereign investors do now? 

The Government considers that the proposed regime would ensure the UK remains an attractive destination for sovereign investors, with benefits comparable to, or more generous than, those offered by most other countries. For investors however, the practical impact would depend on their assets, holding structures and eligibility for the retained exemptions.

Transparent structures such as JPUTs and partnerships may become less attractive for income-generating UK property. REITs held through a sovereign REIT holding company may offer an alternative, but may not be the right solution in every case. Sovereign investors should review their existing holdings, model post-tax returns and compare restructuring options, taking account of the proposed SDLT relief window and its conditions. That exercise may also inform decisions about future UK investment or the disposal of particular assets. Asset managers and those in joint ventures with sovereign investors may also need to consider if any changes to structures or terms are required.

The Government’s consultation is open until 20 January 2027. Technical consultation on draft legislation is expected to follow, ahead of legislation being introduced in Finance Bill 2027/28 and implementation of the regime from 1 January 2029.
