Hi,
Guidance on Capital Gains Tax on personal possessions can be found here:
Capital Gains Tax on personal possessions
Your gain is usually the difference between what you paid for your personal possession and what you sold it for. You can deduct certain costs of buying, selling or improving your personal possession from your gain. You may be able to reduce your gain if you got between £6,000 and £15,000 for your possession when you sold or disposed of it. Subtract £6,000 from the amount you haveve received. Multiply this by 1.667. Compare this with the actual gain and you use the lower amount as your capital gain. You can seei nformation here:
Work out your gain
Once you income is taxed, whatever of the basic rate band remains, allows the same amount of capital gain to be taxed at 10%, with any remaining gain taxed at 20%.
Thank you
