Selling a second property?

CGT on certain UK residential property sales often has a strict 60-day reporting and payment deadline, so early planning can avoid penalties.

If you are selling a second property, such as a buy-to-let or a former home that is no longer your main residence, CGT will usually apply. This is different from selling your main home, which is often covered by Principal Private Residence (PPR) relief and therefore exempt from CGT.

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. 

Most homeowners do not pay CGT when selling their main family home, as PPR relief usually applies. However, CGT is commonly payable on gains from:

  • Buy-to-let properties
  • Second homes or holiday homes
  • Business premises
  • Land
  • Inherited property (based on the increase in value since inheritance, not since original purchase)

Any CGT due on the sale of UK residential property must usually be reported and paid within 60 days of completion. This requires submitting a UK Property CGT return and making a payment on account within that timeframe.

Failing to meet the 60-day deadline can result in penalties and interest, so it is important to plan ahead and obtain advice as early as possible when selling a property that is not fully exempt.
