UK Capital Gains Tax Explained

This section explains the amount of gains and allowances (or tax rates) you can make each year. Check how you become liable for Capital Gains Tax - even though some capital gain is tax-free. Topics covered in this CGT help guide include Business Asset Roll Over Relief, Business Asset Disposal Relief, and wills, probate, and inheritance.


Simply put, Capital Gains Tax (CGT) is an HMRC tax charge used in the United Kingdom. It gets charged against the increase in value from selling or ‘giving away’ property, shares, or personal possessions.

A capital gains charge (or a tax levy) could also be due on other types of accumulated profit. Thus, disposing of an investment or business asset you once owned could be liable for CGT.

As a result of the 2016 Budget, the current charges for Capital Gains Tax in 2022 are now levied at two different rates.

The current charge rate for CGT on most assets (excluding residential property) is 10% for basic rate taxpayers (reduced from 18%). The rate jumps up to 20% for taxpayers who fall into the higher rate tax band (reduced from 28%).

The History of Capital Gains Tax in the United Kingdom

There was one primary driver to the introduction of Capital Gains Tax in the United Kingdom. In fact, it was the rapid growth in property values post World War II.

This led to some property developers ‘deliberately’ leaving office blocks empty. Hence, a rental income could not be established and greater capital gains could be realized.

As a result, the UK Capital Gains Tax system was officially introduced by the Chancellor at the time – Mr. James Callaghan in 1965.
