Ready for Making Tax Digital for Income Tax?

If you’re a sole trader or landlord, the rules change on 6 April 2026 with the rollout of Making Tax Digital for Income Tax. You are legally required to switch to HMRC-Recognised software like Avona if your qualifying income was over £50,000 in the 2024/25 tax year.
