From April 2026, self-employed people and landlords earning over £50,000 annually, will need to follow Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) rules. 

As an accountant or bookkeeper, you will need to prepare yourself, your clients, and your practice for these changes.  Xero’s 3-step ITSA academy has been designed specifically to help you prepare.  You’ll gain access to an on-demand webinar, an in-depth guide and a bespoke one-to-one consultation with an MTD expert. You can sign up here, or keep reading for a summary of some of the key aspects of MTD for ITSA.

What MTD for ITSA means for your clients

From April 2026, your sole trader and landlord clients earning above £50,000 will need to use ITSA-compatible software to keep digital records and submit updates to HMRC. 

In place of the annual Self Assessment, clients will need to send the following every tax year: 

By sending regular updates to HMRC, clients get real-time visibility of their estimated tax bill. So they can plan their budget and cash flow much more accurately. 

This is something Macauley Brammer, Personal Tax Senior at Best Accountancy Services (Plymouth) Ltd highlights to clients: “We explain they’ll have a much more immediate handle on what they owe at any time in a year. While this may invite more questions for the practice, it will help them gain a greater understanding of the process.”

What it means for you and your practice

During the transition to MTD for ITSA, clients will look to you for advice and guidance. Make sure you’re clear on the practical changes to Self Assessments, as well as the software requirements for compliance. 

Macaulay underlines the importance of completing your due diligence on the legislation. “You need to be able to offer technical guidance, so know your subject. Also, make sure you have a plan and work towards it.”

Making Tax Digital is a great opportunity to modernise your practice. Digitalisation increases efficiency, so you can take on new clients, provide additional services, and future-proof your practice.

An intro to quarterly updates and Final Declarations

Quarterly updates

Your clients will need to submit updates containing details of their income and expenditure four times a year. Here’s what that schedule will look like: 

Quarterly period Quarterly deadline
6 April to 5 July 5 August
6 July to 5 October 5 November
6 October to 5 January 5 February
6 January to 5 April 5 May

You’ll need an agent services account (ASA) to send updates on your client’s behalf. Your clients will need to authorise you to do this, and you can send an authorisation request via your ASA. One ASA can be used for multiple clients.

Final Declarations

A Final Declaration finalises a taxpayer’s end-of-year position for tax and determines what they owe. 

As with quarterly updates, the Final Declaration must be submitted via HMRC-approved software

How you can support your clients with MTD for ITSA

Giving your clients plenty of time to prepare for MTD for ITSA will help them make a smooth transition to the new system. Here are some steps you can take to prepare them:

  1. Educate clients on digital record-keeping
    Some of your clients might already be using MTD-compatible software, but others won’t be. The digital links rule is a key aspect of MTD and non-compliance can result in a penalty, so make sure you’re communicating the changes to Self Assessment to your clients.
  2.  Let clients know about the changes to Self Assessment
    From April 2026, clients will need to switch from one annual submission to four quarterly updates. They may need more frequent support with their accounting, so make sure they’re aware of changes to Self Assessment.
  3. Work with clients to ensure they are using MTD-compatible software
    Having MTD-compatible software in place is critical to compliance with ITSA rules. Work with your clients to ensure they have a software package that suits their needs ahead of April 2026.
