What is Making Tax Digital?

Making Tax Digital is a government initiative to digitalise the UK tax system.

In April 2022, MTD rules were extended to all VAT registered businesses, regardless of taxable turnover. This means that businesses who fall within the thresholds must now use compatible software to:

  • keep and maintain digital records
  • submit their tax return directly to HMRC

As such, accountants and bookkeepers must be ready to support their clients with digital record keeping and submitting VAT returns via HMRC-recognised MTD software.

How will Making Tax Digital affect accountants and bookkeepers?

You and your clients must use MTD compatible software to keep digital records and send VAT returns, as of April 2022. You must also sign up for an agent services account via HMRC. VAT registered clients will automatically be signed up for MTD for VAT, so you no longer need to sign them up manually. As long as your clients register for VAT, they won’t need to sign up for MTD for VAT.

According to Xero research, 45% of businesses believe their advisor is more important to them than ever. Clients may call on you for advice and guidance, so it’s crucial to ensure your team is up to speed and can clearly communicate what the rules mean in practical terms.

How to make sure your clients are compliant with MTD for VAT phase 2

HMRC has introduced a new penalty system which will apply from January 2023, so it’s especially important for you to make sure clients are compliant.

Ensure your clients are using HMRC-recognised or bridging software that meets the MTD requirements. Don’t wait until the deadline to talk to your clients about MTD.

How do I submit my client’s VAT return as an agent?

MTD compatible software, such as Xero, has a function where you can submit your client’s VAT return directly to HMRC.

Once you’ve been authorised by a client, you’ll be able to submit VAT returns via their compatible software. Where this feature is located depends on the software, so reach out to your provider if you’re unsure.

What about clients who want to continue using spreadsheets?

If you still have clients who are reluctant to adopt full MTD software and want to continue using spreadsheets, they must use bridging software to ensure they comply with MTD rules.

You can explore more about bridging software, digital links, and the pitfalls to look out for, in our extensive guide.

How to set up your accounting or bookkeeping practice for MTD for ITSA:

From April 2026, MTD for Income Tax Self Assessment (ITSA) will apply to unincorporated businesses and landlords with a total business or property income above £50,000 per year. To prepare, you must:

  • Identify the clients that will be affected by MTD for ITSA.
  • Encourage clients to start digital record keeping now, so they’re confident using software ahead of the deadline.
  • Make sure your clients register before the April 2026 deadline.

Which of my clients will be affected by MTD for ITSA?

Businesses, landlords and sole traders with gross income greater than £50,000 will need to follow MTD for ITSA rules from April 2026.

Businesses, landlords and sole traders with income over £30,000 will need to comply with MTD for ITSA from April 2027.

General partnerships and those earning less than £30,000 annually are yet to be mandated.

Will clients already signed up to MTD for VAT need to also sign up for income tax?

Yes. Clients that meet the criteria will need to sign up for both, separately. They can do this themselves, or you can do this on their behalf.

Note that HMRC will automatically sign up VAT registered businesses for MTD for VAT.

Which of my clients do not need to use MTD for ITSA?

Trusts, estates, and non-residential companies will not need to use MTD for ITSA, but this is subject to change as the rules roll out.

When do my clients need to sign up to MTD for ITSA?

Sole traders and landlords with gross income above £50,000 must be signed up by April 2026. Some businesses can voluntarily sign up to MTD for ITSA now. Check the criteria for voluntary registration here.

How do I sign my client up for MTD for ITSA?

First off, make sure you have:

  • Your government gateway login
  • MTD for ITSA compatible software

You’ll need to sign your client up via compatible software, and you can only do this if they’re already registered for self assessment. HMRC has a guide to signing up for MTD for ITSA.

How to make sure your clients are compliant with MTD for ITSA

Clients will need to use MTD for ITSA compatible software in order to submit their tax returns. Make sure you confirm that they have this software in place before signing them up to MTD for ITSA.
