Explaining MTD - Accountants - HMRC recognised

If you're an accountant, adviser or bookkeeper, read untied's special guide to Making Tax Digital  here.

What is Making Tax Digital for Income Tax Self Assessment?

Making Tax Digital (generally shortened to MTD) is a core HMRC project to modernise the systems that manage taxes in the UK.

It's not just HMRC that will be affected - Making Tax Digital or MTD is changing how we all report and pay our taxes.

It is being rolled out by HMRC one tax at a time. VAT was the first to go live. Businesses registered for VAT with revenue above £85,000 have been filing MTD VAT returns since 2019 - extended to those with sales above £10,000 in 2022.

Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is the next phase of MTD and will affect over 4 million people who are self-employed or renting out property. It will be mandated from 2024, but untied is already live and helping people get used to this new way of managing our taxes.


What is MTD?

The biggest change to income tax reporting in a generation

MTD places mandatory digital record-keeping requirements on businesses and introduces quarterly reporting requirements.

Instead of one tax return submitted many months after the end of the tax year, MTD involves quarterly reporting during the year, with any final numbers confirmed after the year-end.

Will I be able to file my taxes via HMRC?

HMRC has a long-term ambition to become one of the most digitally advanced tax administrations in the world. Their main goal with MTD ITSA is to make the tax administration more effective, more efficient, and simpler for taxpayers. To help do this, HMRC will use the expertise of software providers like untied, to build digital solutions that make it simple and stress-free to do your taxes.

Accountants and MTD

Can I use untied if I already have an accountant?

Yes, absolutely! Accountants will need to use MTD recognised software with their clients too. Our adviser portal has been co-designed with accountants, ––specifically with MTD in mind––and we continue to work closely with accountants on our MTD early adopter programme.

We've created a Making tax Digital guide for accountants.
