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.

Remember, HMRC calculates your qualifying income from your gross turnover across all your sole trades and rentals. That means all the money you brought in before deducting expenses, not your final profit.
