The UK government’s transition to Making Tax Digital for Income Tax Self-Assessment (MTD for ITSA) is rapidly approaching and with significant changes coming in 2026 and 2027, it’s crucial to understand how these new requirements will impact self-employed individuals, landlords, and small businesses—and what you can do to get prepared.
One of the most important developments is the public testing phase for MTD for ITSA, which will officially begin in April 2025. This is a critical opportunity to familiarise yourself with the new system before the rules are fully enforced. Let’s break down the upcoming changes, key dates, and how you can get involved in the testing phase:
What is MTD for ITSA?
Making Tax Digital (MTD) represents a fundamental shift in how taxpayers manage their income and taxes. Instead of submitting a Self-Assessment return once a year, individuals and businesses will be required to:
- Keep digital records of income and expenses
- Submit quarterly updates to HMRC
- Receive an estimated tax calculation to help with budgeting
At the end of the tax year, individuals will finalise their tax information using MTD-compatible software, which will also include non-business income and other final adjustments. This system is designed to streamline the process, reduce errors, and ensure greater accuracy in tax reporting.
Why You Should Get Ready for the 2025 Public Testing Phase
April 2025 marks the start of the public testing phase for MTD. HMRC is inviting businesses to volunteer for this phase, allowing you to trial the new system ahead of its official rollout. This gives you a huge opportunity to get comfortable with the changes and prepare for the official deadlines in 2026 and 2027.
The testing phase will allow business owners to try out the MTD for ITSA system, test out MTD-compatible software, and provide feedback to HMRC. Participating in the testing phase will help ensure that the system is user-friendly and identifies any potential issues before it becomes mandatory.
By getting involved in this public testing phase, you’ll gain first-hand experience with how MTD-compliant software will handle your tax reporting. It will also help you make sure that your systems and processes are set up properly before the deadline.
The Key Dates for MTD for ITSA: What You Need to Know
As per the government’s revised timeline, MTD for ITSA will be phased in over the next few years. Here’s what you need to know:
April 2026 – Self-Employed and Landlords with Income Over £50,000
From April 2026, self-employed individuals and landlords earning over £50,000 will be required to submit quarterly updates to HMRC through MTD-compatible software. This is the first major deadline for MTD for ITSA.
- What do you need to do?
If you are a self-employed individual or landlord with an income over £50,000, you will need to start keeping digital records and submit quarterly income and expense reports. Using software like Xero will help you get prepared for these requirements.
April 2027 – Self-Employed and Landlords with Income Between £30,000 and £50,000
In April 2027, the scope of MTD for ITSA will expand to include individuals with income between £30,000 and £50,000.
- What do you need to do?
If your income falls into this category, you’ll need to ensure you’re using MTD-compatible software to submit quarterly updates. The sooner you transition to digital record-keeping, the smoother the process will be when the regulations come into effect.
The Importance of Transitioning to Digital Early
While the official deadlines may seem far off, transitioning to MTD-compliant software now is essential for the following reasons:
- Smooth Transition:
The longer you wait, the more stressful the process will be. By making the shift to digital now, you’ll be able to adopt the new system gradually, rather than scrambling to meet the deadlines at the last minute. - Easier Compliance:
Digital record-keeping is more accurate and efficient than manual methods. Using software like Xero ensures that you can easily capture your income and expenses, and generate the necessary quarterly reports to send to HMRC. This reduces the risk of errors and saves you time. - Prepare for the Testing Phase:
Participating in HMRC’s public testing phase in 2025 is a fantastic opportunity to test the system in advance. This phase will help you familiarise yourself with MTD-compliant software before the rules are enforced in 2026 and 2027. - Long-Term Benefits:
Once fully implemented, MTD for ITSA will make managing your taxes much simpler and less time-consuming. You’ll no longer have to prepare and submit a lengthy Self-Assessment tax return at the end of the year. Instead, your quarterly updates will provide a more accurate, up-to-date picture of your tax obligations.
Smaller Businesses: What Does the Future Hold?
Although businesses under the income threshold aren’t required to adopt MTD for ITSA immediately, it’s still a good idea to start using MTD-compliant software now to get ahead of any future changes. Adopting digital systems early will make it easier for you to meet potential requirements as they arise.
