I can't use the unused personal allowances against Capital Gains, Right?

I don't have a job in the UK. The only income for me is investing in the stock market. Last tax year, I made a profit on stock market so I think I have to pay for the Capital Gain Tax. On HMRC website stated that: -I only have to pay Capital Gains Tax on your total gains above an annual tax-free allowance. -The Capital Gains tax-free allowance is £6,000. If my profit on investment is £20,000, my taxable gains on CGT is: deduct the "profit (£20,000)" from "Capital Gains tax-free allowance(£6,000)" =£20,000 - £6,000 = £14,000 If I pay basic rate Income Tax, so the tax rate is 10%. This means I’ll pay £1,400 (=£14,000 x 10%) in Capital Gains Tax. Even I have £12,570 unused personal allowances, I can't use the unused personal allowances against Capital Gains. Please correct me if I am wrong. Thanks.

Hi,

That is correct, personal allowances cannot be used against capital gains.

Thank you.
