2025/26 and Making Tax Digital (MTD)
From 6 April 2026, HMRC will begin phasing in Making Tax Digital for Income Tax Self Assessment (MTD for ITSA). This applies to sole traders and landlords, depending on their income levels.
Here’s how the phasing works:
From 6 April 2026: If your combined self-employment and property income (before expenses) was over £50,000 in the 2024/25 tax year, you must follow MTD rules.
From 6 April 2027: If your combined income was over £30,000 in the 2025/26 tax year, you’ll need to comply with MTD.
From 6 April 2028: The threshold is planned to drop further to £20,000, based on income in the 2026/27 tax year.
What this means for you:
You’ll need to keep digital records of income and expenses.
You’ll submit quarterly updates to HMRC using approved software.
You’ll still need to complete a final declaration (end-of-year return).
If you prefer to manage your quarterly submissions yourself, we can handle the final return.
