Will I pay capital Gains Tax or Income Tax on sale of US stocks?

Hi there I have US stocks that I am looking to sell but am unsure whether I would need to pay CGT or Income tax, and what would determine this? Also, would this be just on the gain? Kind regards Brad

Hi,

Based on the limited information, it is capital gains and is on the gain only.

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

Thank you.
