About the Capital Gains Tax Calculator
Use this UK capital gains tax calculator to estimate CGT on property, shares and investments for the 2026/27 tax year.
Our Capital Gains Tax calculator helps UK taxpayers estimate their CGT liability when selling assets such as property, shares, or other investments. The calculator takes into account your other income to determine which CGT rate applies and automatically deducts the annual exemption.
CGT rates differ between residential property and other assets. Property sales attract rates of 18% (basic rate taxpayers) or 24% (higher/additional rate taxpayers), while other assets are taxed at 10% or 20% respectively. The calculator applies the correct rates based on your total income and the type of asset you're selling.
Remember that certain reliefs may reduce your CGT liability, including Private Residence Relief for your main home, Business Asset Disposal Relief for qualifying business disposals, and the ability to offset capital losses. For complex situations, we recommend consulting with a tax professional.
