Hi zanny71 zdanowicz,
Capital gains arising from any source other than residential property, are now reported using the online capital gains realtime service at:
Report and pay your Capital Gains Tax
For gains arising in 2022 to 2023 tax year, need to be reported online before 31 December 2023, otherwise a Self Assessment Tax Return will need to be submitted to report the gains.
Payment of the tax would be due by 31 January 2024, whichever reporting method is used.
The lower rate of Capital Gains Tax for non residential property gains is 10% and the higher rate of captital gains tax is 20%.
For residential property, the rates are 18% and 28%.
Thank you.
