A UK REIT — real estate investment trust — is a company that pays no corporation tax on the profits and gains of its property rental business, in exchange for distributing at least 90% of those rental profits to shareholders, who are taxed on the income instead. One layer of tax rather than two. Since the rules were loosened in 2022 and 2023, the regime has quietly stopped being a listed-company club: private REITs held by institutional investors are now routine, single-property REITs are possible, and the question "should our property vehicle be a REIT" has a different answer than it did five years ago.
Here is how the regime works in 2026 — for investors deciding what a PID on their tax return means, and for property businesses weighing conversion.
The deal: no corporation tax, mandatory distributions
Inside the ring-fence, a REIT's qualifying property rental business — UK and overseas rents, and gains on disposal of rental properties — is exempt from corporation tax. Development-for-sale profits and other trading activities sit outside the exemption and are taxed normally (developing a property to hold and let can stay inside the ring-fence). The price of the exemption is the distribution obligation: at least 90% of property rental profits must be paid out for each accounting period (and 100% of PIDs received from other REITs), within twelve months.
Those distributions are property income distributions (PIDs) — legally distributions, but taxed under their own property-income rules rather than as dividends. The REIT deducts 20% income tax at source; investors are taxed on PIDs as property income at their marginal rates — no dividend allowance, no dividend rates. UK companies, charities, registered pension schemes and ISAs can receive PIDs gross, which is why REITs sit so naturally inside pensions and ISAs: the property income arrives with no tax leakage at all. Individual investors holding REIT shares outside a wrapper should expect their platform's tax voucher to split PID from ordinary dividend — both can be paid, and they go in different boxes on the return.
Joining the club: the conditions in 2026
The gateway conditions have been progressively relaxed, and the current list looks like this:
- Listing — no longer always required. Since April 2022, a company needs no stock-exchange admission if at least 70% of its shares are held by institutional investors — pension funds, insurers, sovereign funds, certain fund vehicles. This created the "private REIT", now the default structure for institutional UK property ventures.
- Balance of business: at least 75% of gross assets and 75% of profits must relate to the property rental business.
- Properties: at least three properties with none exceeding 40% of the total — or, since April 2023, a single commercial property worth £20 million or more.
- Interest cover: property profits must cover property financing costs at least 1.25 times; drop below and a tax charge claws back the advantage on the excess gearing.
- Not close: the REIT cannot be a close company, except where it is close only because of institutional investors.
- Distribution compliance, a UK tax residence requirement, and one class of ordinary shares.
There is no entry charge — the old 2% conversion levy died in 2012 — so conversion is a compliance exercise, not a purchase. The 2024 Finance Act tightened the institutional-investor definitions (fund vehicles must show genuine diversity of ownership or pass non-close tests), which is worth checking carefully before assuming a structure qualifies.
Who actually benefits from converting
The regime rewards a specific shape of business: substantial rental portfolios held for income, with investors who would otherwise suffer corporation tax inside the vehicle and then tax again on extraction. For a family property company sitting on £30 million of let commercial property, REIT status can remove 25% corporation tax from the rental profits permanently — the arithmetic is compelling, though the admission route is only half the entry ticket: the close company condition must be passed on its own terms, and a family-held vehicle does not stop being close just because its shares are admitted somewhere.
It rewards development-and-sale businesses much less: trading profits stay taxable, and the 75% tests punish mixed activity. And the close company condition means a REIT genuinely cannot be a handful of individuals' private vehicle — the regime is built for wide or institutional ownership, and structures that try to fake it tend to fail the 2024-tightened definitions.
Roughly forty REITs trade on the London market, from the giants down to specialist vehicles for logistics, healthcare and supermarkets, with an uncounted and growing population of private REITs behind them since 2022.
The compliance reality
REIT status is maintained, not merely obtained. The 75% tests are measured continuously, the interest cover test punishes over-gearing in a rising-rate environment, distributions must be tracked against the 90% obligation with the twelve-month clock in view, and PID withholding needs administering across a shareholder register that mixes gross and net recipients. Breaches mostly trigger tax charges rather than expulsion — HMRC can only remove serious or persistent offenders — but the charges are real money, and the financial reporting around the ring-fence (exempt versus residual business) is its own discipline.
For investors, the practical points are simpler: hold REITs in pensions and ISAs where the gross-payment machinery works in your favour; outside wrappers, expect property-income treatment and file accordingly; and for non-resident investors, treaty claims on the 20% PID withholding are frequently available and frequently unclaimed.
