Capital Gains Tax on certain residential property sales must be reported and paid within 60 days to avoid penalties and interest.

The annual exempt amount applicable to Capital Gains Tax (CGT) is currently £3,000. CGT is normally charged at a simple flat rate of 24% and this applies to most chargeable gains made by individuals. If taxpayers only pay basic rate tax and make a small capital gain, they may only be subject to a reduced rate of 18%. Once the total of taxable income and gains exceed the higher rate threshold, the excess will be subject to 24% CGT. 

These rates also apply to gains from the sale of residential property, except for a principal private residence (PPR), which is usually exempt from CGT. Most homeowners don’t pay CGT when selling their main family home but gains from other types of property may be taxable.

This includes:

Any CGT due on the sale of UK residential property must usually be reported and paid within 60 days of the completion date. This means a CGT return must be submitted and a payment on account made, within that 60-day window.

Failing to meet the deadline can lead to penalties and interest, so it’s important to plan ahead and ensure timely reporting whenever a non-PPR property is sold. And if required, we can help you with the computations and filing formalities.
