What CGT applies when a non-resident sells UK property, and what is the 60-day return?

Non-residents can generally rebase the acquisition cost to the property's market value at April 2015 for residential property or April 2019 for commercial and mixed-use property, so only the gain arising since that date is normally taxable, though an election can instead use the whole ownership period gain if that produces a better result.

Individuals pay CGT at 18% or 24% depending on their total income and gains for the year, retain the annual exempt amount if entitled to it, and can deduct qualifying costs such as agent and legal fees on the sale and the original purchase.

The 60-day clock starts on completion, not exchange, and applies even where the calculation shows no tax is due, such as a loss or full use of reliefs, because the return itself is mandatory for UK property disposals by non-residents. Late filing brings automatic penalties similar to Self Assessment lateness penalties.

The gain is also reported again on the following year's Self Assessment return where one is required, at which point the estimated tax paid within 60 days is reconciled against the final liability, with any balance due or refund arising at that point.

Our fixed monthly packages for a UK limited company start at £89 plus VAT and run to £169 and £289 plus VAT as bookkeeping, VAT, payroll and reporting are added. One-off filings are sold at fixed prices, and the Companies House fees we pay for you are charged at cost with no VAT added. Overseas owners are quoted on exactly the same published prices as UK-resident clients.

Rates, thresholds and deadlines here reflect the 2026/27 UK position and current Companies House and HMRC guidance. Check GOV.UK, or ask us, before relying on them for your own company.
