CGT on property - which tax year?

Hi, I'm planning on selling a property by auction in late March 2024, and it will have a CGT liability. I'd like to confirm which tax year the liability will be for. The auction contracts will exchange on the day of the auction, and will be binding. But, completion will take place 28 days later, taking it into the next tax year. Does HMRC allow me to place the gain in the 2023-2024 tax year based on the binding contract, or do I need to place it in 2024-2025? Hope this is clear! Thanks!

Hi SonnyH,
The year of disposal is the date contracts are exchanged( date missives signed).
If any conditions are attached then its when all the conditions are met.
The 60 days Poperty Payment Disposal starts day after completion (exchange of keys).
Thank you. 
 

If I sell a property is the rate of CGT payable calculated according to the existing law/rate at disposal date or according to a new rate that may have become law subsequently?

Hi,

A disposal of residential property is subject to the rates of Capital Gains Tax in use in the tax year the asset is disposed of. The table below will determine the rate of tax to be applied:

Capital Gains Tax: what you pay it on, rates and allowances

Thank you.
