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.

What they say
We've recently started using Martin for our accounting requirements and I am already very impressed. His response time to enquiries, support when setting up new accounts and accounting advice is excellent. We have also received weekly updates on the newest government schemes during lockdown which was incredibly helpful. Looking forward to continuing using his services in the future.
Martin and Gold Stag Accounts have been great in getting my business accounts and book keeping in order, freeing up my time to help grow the business.
