UK Company Accounts and Tax- CT600 Return for accounting periods longer than 12 months
It should be possible in Xero to file a split corporation Tax if accounting period is longer than 12 months as it happens with new a company filing their corporation tax for the first time. It is not possible to do so at the moment and this could come in handy.
Hey Jake, we are really happy to announce that this is in the process of being released in Xero✨ Support for Corporation Tax returns covering accounting periods longer than 12 months is now rolling out to UK small business organisations. The rollout is happening in stages, and we expect it to reach 100% by 22 October 2026, so it may become available in your organisation before then. Once available, Xero will prepare two Corporation Tax returns for an accounting period longer than 12 months and submit them separately. The second return will be submitted once the first has been accepted.
Thanks again for helping us improve Xero.
