The reforms target qualifying foreign governments and sovereign wealth funds rather than everyday overseas buyers, with transitional relief proposed to soften the move to new ownership structures.
The UK is removing tax exemptions for foreign sovereign wealth funds on British property income and sales from January 2029, expecting to raise £690 million in the first year – a move that could reshape how state-backed investors structure their UK real estate holdings. While the changes target foreign governments rather than individual overseas buyers, agents managing institutional property portfolios should note the new 15 per cent tax rate proposed for REIT investments, plus transitional relief on stamp duty that gives affected investors until 2029 to restructure.
Foreign governments and sovereign wealth funds, which invest government money in assets such as property, shares and infrastructure, could face higher tax bills under plans to remove longstanding exemptions on British rental income and property sales.
The changes, announced in the UK’s October Budget, would bring certain property income and gains earned by foreign sovereign investors into the tax system from 1 January 2029.
The reforms could affect major international investors with commercial and residential property holdings across Britain, potentially prompting them to reconsider how their assets are owned and managed.
Under the existing system, qualifying foreign governments and sovereign wealth funds can avoid certain UK taxes on investment income and capital gains that would ordinarily apply to private investors.
However, the UK government wants to replace those arrangements with clearer rules, arguing that the current system lacks transparency.
According to the UK Treasury’s consultation, the proposed framework is intended to improve transparency and provide greater certainty for sovereign investors.
The government’s Budget forecasts the changes will raise £690 million (approximately A$1.31 billion) in the 2029–30 financial year.
What would change for property investors?
From January 2029, qualifying foreign sovereign investors would generally become liable for UK tax on rental income and gains made when selling British property, including certain investments held through companies or other structures.
The changes could affect the returns generated by existing property portfolios and influence how sovereign wealth funds approach future acquisitions.
However, the government is proposing special tax arrangements for qualifying investments held through real estate investment trusts (REITs), including a 15 per cent rate on relevant property income distributions.
The measure is designed to keep Britain attractive to international investment while ensuring foreign government-backed investors contribute more tax on income generated by UK property.
The Treasury is also proposing transitional measures to help investors restructure existing holdings, including relief from certain stamp duty costs and adjustments to the tax value of eligible assets.
These arrangements could help reduce the immediate financial impact of moving property investments into new ownership structures.
What does it mean for the property market?
Sovereign wealth funds are significant investors in British commercial property, including office buildings, retail assets and major developments.
The proposed changes could influence investment decisions by reducing after-tax returns on some assets, although the impact would depend on how individual portfolios are structured.
Investors may also need to review existing holdings and consider whether REIT structures offer a more suitable way to manage their British property investments.
Importantly, the reforms would not apply to all foreign property buyers. They specifically concern qualifying foreign governments, sovereign wealth funds and other state-backed investors, rather than overseas individuals buying homes.
The government has opened a consultation on the proposals, which closes on 20 January 2027, before draft legislation is developed.
If implemented as planned, the new rules would take effect on 1 January 2029, giving affected investors time to prepare.
For Britain’s property sector, the changes could alter how some of the world’s largest institutional investors assess the costs and returns of holding UK real estate.
