The first Making Tax Digital for income tax (MTD) quarterly update filing deadline of 7 August has only just passed, but HMRC is not letting the dust settle on compliance.
HMRC has previously indicated that it expected around 864,000 taxpayers to be required to join MTD from April 2026. Statistics published today indicate that over 570,000 have actually registered to date, with more than 436,000 successfully filing quarterly updates.
In the same announcement, HMRC has said that while it is happy with these figures, it is not going to wait for the remaining taxpayers to sign themselves up. Instead, starting this September, HMRC will sign up any remaining taxpayers it believes to be in scope of MTD for 2026/27.
What is actually going to happen?
HMRC has said that, starting in September, it will sign up those taxpayers for MTD who should have joined earlier this year. Sign-up will happen in stages over the following months, with more detailed guidance to follow in August.
Importantly, this only affects those taxpayers who are mandated for 2026/27 – anyone required to join in April 2027 or 2028 is still expected to sign themselves up (or ask their agent to do this) in the usual way.
Once signed up by HMRC, the taxpayer will receive a letter or digital message (depending on their contact preferences) advising them what this means and the next steps they need to take.
This will include all the usual steps to get ready to use MTD, such as finding compatible software, starting to keep digital records etc. However, there will also be an additional ‘checking’ step recommended by HMRC.
We understand that taxpayers who are signed up by HMRC will be asked to log into their personal tax account/business tax account (or for their agent to go into their agent services account) and check that HMRC’s records are up to date.
Once logged into the relevant records, the account will list those businesses which HMRC believes to be active and within MTD from April 2026. There will then be the option to either confirm the details are up to date, or remove businesses that are no longer active and/or add any new businesses.
This is an important step, as HMRC’s records are based on historic tax return data, so failure to check might result in, for example, HMRC expecting quarterly updates for a business that is no longer being carried on.
