Hi, I completed my SATR for 23/24 and this calculated payments on account being due. Since then I have sold my business and only have a future tax liability for capital gains tax on the share disposal - no other income expected in 24/25. Can I reduce my January 25 and July 25 payments on account to £nil and pay the tax on the share disposal by 31 Jan 2026, or should I be paying the value of the CGT in my January 2025 1st payment on account? Many thanks,
