Full answer
The timing of Capital Gains Tax payment in the UK depends on the type of asset sold. For shares, funds, and most non-property assets: gains are reported on your Self Assessment tax return and payment is due by 31 January following the end of the tax year in which the disposal occurred. For 2026/27 disposals, CGT is due by 31 January 2028. For UK residential property (buy-to-let, second homes, inherited property — not your main residence where PPR applies): since April 2020, you must report the gain and make a payment on account within 60 days of completion, using HMRC's online CGT reporting service (separate from Self Assessment). Failure to report within 60 days incurs an automatic £100 late filing penalty. The Annual Exempt Amount (AEA) for 2026/27 is £3,000 per individual. Gains up to this amount are tax-free. Above £3,000, CGT rates are: shares/investments 18% (basic rate) or 24% (higher rate); residential property 18% (basic rate) or 24% (higher rate). Both rates changed in October 2024 and now match for investments and property. Losses in the same tax year are offset against gains before the AEA. Unused losses can be carried forward indefinitely. Transfers between spouses and civil partners are at no gain no loss, effectively deferring CGT.
