What is 60 day Capital Gains Tax reporting?
Last verified 23 October 2026
The 60 day rule means that when you sell a UK residential property and have Capital Gains Tax to pay, you must report the sale and pay the tax within 60 days of completion. It applies to rental properties and second homes.
Why it matters to landlords
You report through a Capital Gains Tax on UK property account online, or on a paper form, and HMRC gives you a payment reference. Joint owners each report their own share of the gain. If you are registered for Self Assessment, you must also include the sale on your tax return for that year. UK residents do not need to report online if their total gains are below the tax free allowance.
Non-residents must report every sale or disposal of UK property or land by the deadline, even with no tax to pay. For individuals, gains are taxed at 18% within the basic rate band and 24% above it, after the annual exempt amount of £3,000 for 2026 to 2027. Reporting or paying late can mean interest and a penalty, so get your figures, including costs of buying, selling and improving, ready before completion.
Example
You complete the sale of a buy to let flat on 10 March 2027 with a taxable gain. You must report the sale and pay the tax by 9 May 2027, then include it on your 2026 to 2027 return.
