The Next Step in Digital Tax: What MTD for Income Tax Means

New Filing Requirements for Sole Traders and Landlords 

Making Tax Digital for Income Tax (MTD IT) is the next major phase of HMRC’s digital tax programme and represents a fundamental change in how sole traders and landlords manage and submit their tax information. 

Under MTD IT, affected taxpayers will need to move away from paper records and traditional annual Self Assessment filing, and instead adopt MTD-compatible Income Tax software to manage ongoing compliance. 

When Does MTD for Income Tax Apply?

MTD for Income Tax will be introduced in stages, based on income thresholds: 

  • From April 2026 
    Mandatory for sole traders and landlords with qualifying income over £50,000 
  • From April 2027 
    Mandatory for those earning over £30,000 
  • From April 2028 
    Expected to apply to individuals with income over £20,000 

These thresholds relate to gross qualifying income, not profit. 

Who Needs to Follow MTD for Income Tax?

Capium ensures full compliance with HMRC requirements while keeping workflows simple and manageable. 

Key MTD IT Requirements

Under MTD for Income Tax, sole traders and landlords will be required to: 

  • Maintain digital records

    Keep income and expense records digitally using HMRC-recognised MTD IT software

  • Submit quarterly updates to HMRC

    Replace the traditional annual-only approach with four quarterly submissions per tax year

  • Complete an End of Period Statement (EOPS)

    Finalise figures for each income source after the tax year ends

  • Submit a Final Declaration

    Confirm all income and allowances by 31 January following the end of the tax year

MTD IT does not mean four tax bills a year: It means more regular reporting to HMRC, with tax still finalised annually. 

What Happens to Paper Records and Manual Filing?

For individuals within the scope of MTD IT, traditional paper records and manual online Self Assessment filing will no longer be accepted by HMRC. 

Only those outside the MTD thresholds or formally exempt will be able to continue using non-digital methods. 

This makes choosing the right MTD Income Tax software essential for both accountants and their clients. 

What Are the Risks of Non-Compliance?

Failing to comply with MTD IT requirements may result in: 

  • Late submission penalties 
  • Increased HMRC scrutiny 
  • Additional administrative burden for accountants and clients 
  • Higher long-term compliance costs 

Preparing early helps practices avoid last-minute disruption and gives clients time to transition at a manageable pace.

We were growing tired of desktop software with problematic updates, which had to be downloaded and applied frequently; expensive multiple-user licensing and maintaining a costly IT infrastructure to run the desktop software for multiple users who worked in different locations. Then came along Capium – Everything we needed, all in the cloud, easy to use and inexpensive. Did we mention the great customer support? What’s not to like? We love it.”
