Quality Improvements
The following items have been fixed in this release.
Duplication of entries
After installing version 2025.300, we identified an issue affecting certain capital allowance screens with a grid structure. In cases where the period of account spans more than one accounting period, adding a new entry could result in duplicate items appearing. This affected screens such as Structures and Buildings Allowances and BPRA. The issue has now been resolved in this release.
Items to be included in a later release
CT600P creative industries supplementary pages
The CT600P creative industries supplementary pages will be included in a later release.
New Computation Format
HMRC is introducing a standardised format for the Corporation Tax Computation, which will apply to all companies regardless of size or complexity. This change will be rolled out gradually over the next few years, starting with specific areas such as Capital Allowance claims for trades, before extending to all sections of the computation.
Our software will incorporate the new standard format as soon as HMRC releases each update.
