UK property tax for overseas investors: a complete guide

13 August 2025 / Insight posted in Articles

When exploring UK property tax for overseas investors, understanding the range of taxes involved is vital for anyone buying residential property from abroad. Whether you’re a non-resident individual or a company, knowing which charges apply and how to manage them helps you make informed decisions and potentially save significant sums.

Stamp duty land tax for overseas buyers

Non-UK residents face a residential stamp duty land tax surcharge of 2%, added to standard rates, while additional property ownership can trigger another 5%. Companies often pay even more – up to 17% once all surcharges are included.

Deducting rental costs

Both individuals and companies can deduct such costs as letting agent fees, insurance and property maintenance from rental income. However, individuals can only claim mortgage interest relief at the basic rate, typically 20%, while companies face no such restriction.

Reporting rental income

Non-resident landlords must file a UK self-assessment return and are generally subject to a 20% withholding tax unless HMRC approval is obtained to receive rental income gross. Companies must submit corporation tax returns on rental profits, currently taxed at a main rate of 25%, and register their ultimate beneficial ownership with Companies House.

Annual tax on enveloped dwellings

Properties worth more than £500,000 held through corporate structures may fall under the annual tax on enveloped dwellings (ATED) regime. These charges are not deductible for tax purposes, though relief is often available if the property is commercially let to an unconnected tenant.

Capital gains tax on sale

Overseas individuals selling UK property must report any gains under the non-resident capital gains tax regime. Gains are calculated from a 6 April 2015 market value baseline and are taxed at either 18% or 24%, depending on the taxpayer’s income band. Companies pay corporation tax on all gains but do not benefit from the exemptions and allowances available to individuals.

Inheritance tax

UK residential property is subject to inheritance tax (IHT), even when held through an overseas company. Individuals are charged IHT at 40% on death for property exceeding the nil-rate band (£325,000). Holding property through a company does not protect non-UK shareholders from IHT on shares in UK property-holding companies.
