This week’s miscellaneous updates – 24 March 2025

In this week’s miscellaneous updates, HMRC has released a new online calculator to work out the adjustment needed for disposals of assets on or after 30 October 2024 when the rates of capital gains tax changed and as expected, the UK has revoked its Double Taxation Treaties with Russia and Belarus. HMRC is holding a webinar on voluntary payrolling of benefits and has sent an email about year-end processes for payroll. The Institute for Fiscal Studies (IFS) has announced the appointment of its next Director and the latest schedule of HMRC Talking Points live and recorded webinars for tax agents are available for booking. Spaces are limited, so take a look now and save your place. And finally, check HMRC’s online services availability page for details of planned downtime and the online services affected.

Mid-year CGT rate changes

HMRC has published a new online calculator to work out the self-assessment (SA) adjustment needed for disposals of chargeable assets on or after 30 October 2024 when the rates of CGT changed at the Autumn Budget 2024.  This is because the  2024/25 SA return will not automatically calculate using the correct CGT rates for the 2024/25 if there are disposals on or after 30 October 2024.

Hence taxpayers may need to work out an adjustment to the tax automatically calculated and can use the adjustment calculator to do this.

Revocation of Russia and Belarus tax treaties

Following HMRC’s announcement in February that the UK would be suspending its Double Taxation Treaties with Russia and Belarus, legislation revoking the original Orders giving effect to the UK-Russia and UK-Belarus Double Taxation Treaties has now been introduced via statutory instruments.

These will both cease to have effect from:

• 6 April 2025 for Income Tax and Capital Gains Tax, and
• 1 April 2025 for Corporation Tax.
