Self-assessment
CGT is otherwise collected as part of the self-assessment system, and is due in one amount on 31 January following the tax year. Therefore, a CGT liability for the tax year 2021–22 will be payable on 31 January 2023.
Self-assessment payments on account are not required in respect of CGT.
A residential property gain is still included in the self-assessment computation, with the payment on account deducted from the total CGT liability.
EXAMPLE 6
For the tax year 2021–22, Adam has a salary of £44,000. During the year, he made net personal pension contributions of £4,400. On 15 June 2021, Adam sold an antique table and this resulted in a chargeable gain of £21,800.
For the tax year 2021–22, Bee has a trading profit of £60,000. On 20 August 2021, she sold an antique vase and this resulted in a chargeable gain of £20,100.
For the tax year 2021–22, Chester has a salary of £43,500. On 31 October 2021, he sold a residential property and this resulted in a chargeable gain of £47,300.
Adam
Adam’s taxable income is £31,430 (44,000 less the personal allowance of 12,570). His basic rate tax band is extended to £43,200 (37,700 + 5,500 (4,400 x 100/80)), of which £11,770 (43,200 – 31,430) is unused.
Adam’s taxable gain of £9,500 (21,800 less the annual exempt amount of 12,300) is fully within the unused basic rate tax band, so his CGT liability for 2021–22 is therefore £950 (9,500 at 10%). This will be due on 31 January 2023.
Bee
Bee’s taxable income is £47,430 (60,000 – 12,570), so all of her basic rate tax band has been used. The CGT liability for 2021–22 on her taxable gain of £7,800 (20,100 – 12,300) is therefore £1,560 (7,800 at 20%). This will be due on 31 January 2023.
Chester
Chester’s taxable income is £30,930 (43,500 – 12,570), so £6,770 (37,700 – 30,930) of his basic rate tax band is unused. The CGT liability on Chester’s taxable gain of £35,000 (47,300 – 12,300) is therefore:
