What is the UK Capital Gains Tax (CGT) Calculator?
The UK Capital Gains Tax (CGT) Calculator is an investment planning tool designed to help UK taxpayers estimate tax liabilities when disposing of assets like shares, cryptocurrency, or residential property.
Capital Gains Tax is charged on the profit (gain) you make when you sell or dispose of an asset that has increased in value:
• Annual Exempt Amount (Allowance): The UK tax-free allowance for capital gains is £3,000 for individuals. You only pay CGT on gains that exceed this threshold.
• CGT Rates by Asset Category:
- Residential Property (Non-PPR): Under current rules, basic-rate taxpayers pay 18% on property gains, while higher and additional-rate taxpayers pay 24% (Private Residence Relief applies if the property was your main home).
- Shares and Other Assets: Basic-rate taxpayers pay 10% on share gains, while higher and additional-rate taxpayers pay 20%.
• Marginal Bracket Allocation: The taxable gain (above the £3,000 allowance) is added to your other taxable income for the year. The portion of the gain that falls within the basic-rate bracket (£50,270 limit) is taxed at the basic CGT rate, while any excess is taxed at the higher rate.
This calculator computes your net taxable gain, applies the £3,000 annual allowance, determines the tax rates based on your other income and asset type, and estimates the final tax due to HMRC.
