Estimate UK Capital Gains Tax owed after the annual exempt amount, based on your income tax band.
Everyone has a tax-free Capital Gains Tax allowance (the annual exempt amount) each year. Gains above that are taxed at 18% if you're a basic-rate taxpayer or 24% if you're a higher/additional-rate taxpayer (rates shown are for most assets excluding residential property, which has its own rates).
