The Real Time Capital Gains Tax Service is a system that is used in the United Kingdom to report and pay capital gains tax in real-time. The system was introduced by HM Revenue and Customs (HMRC) in April 2020, and it applies to individuals and companies who sell assets (such as shares or property) and who are required to pay capital gains tax on the sale.

Under the Real Time Capital Gains Tax Service, taxpayers are required to report and pay their capital gains tax within 30 days of the disposal of the asset. This means that they must report the sale and pay the tax owed on the sale within 30 days of completing the sale, rather than waiting until the end of the tax year to pay the tax.

The Real Time Capital Gains Tax Service is intended to make it easier for taxpayers to pay their capital gains tax and to reduce the risk of taxpayers underpaying or failing to pay their taxes. If you have any questions about the Real Time Capital Gains Tax Service or need help with your capital gains tax obligations, you can contact HMRC for assistance.
