MTD ITSA 2026 deadline
Get Ready for Making Tax Digital for Income Tax (MTD ITSA)
If you’re a sole trader or landlord, you may have heard whispers about something called MTD ITSA. It might sound like another bit of red tape, but really it’s all about moving tax reporting online to make life easier (once you’re set up!).
At Seamount Accountancy, we know that the thought of extra HMRC requirements can feel daunting — but don’t worry, we’re here to help you understand what’s changing, and what you can do now to be prepared.
What is MTD ITSA?
MTD ITSA stands for Making Tax Digital for Income Tax Self Assessment. From April 2026, if you’re:
- A sole trader with annual business income over £50,000, or
- A landlord with rental income over £50,000,
…you’ll need to follow the new rules.
Those earning over £30,000 will be included from April 2027.
Instead of filing one Self Assessment tax return each year, you’ll be expected to:
- Keep digital records of your income and expenses.
- Send quarterly updates to HMRC using approved software.
- Submit a final year-end declaration.
What Does This Mean for You?
For many business owners and landlords, this is a big change. The days of paper records, spreadsheets, or once-a-year submissions will be over. Instead, you’ll need to get comfortable with digital bookkeeping software, such as Xero, QuickBooks, or FreeAgent.
The good news is that this system should give you a clearer, more up-to-date picture of your tax position throughout the year — no more nasty surprises in January!
