Navigating MTD for Income Tax with your clients

In this series of guides, we’ve collated all the information you need to help you and your practice get Making Tax Digital done.

Every accountant is familiar with the shoebox. The one crammed with crumpled receipts, delivered annually with a sheepish grin. Or the client who stubbornly clings to their trusty spreadsheet, resisting any mention of cloud-based software.

Working in a service-led profession, you’ve likely adapted to these ways of working in an effort to support your clients, even when better tools are available. But with Making Tax Digital (MTD) for Income Tax now here, it’s time to shake things up, not just for clients but for your practice too.

In this guide, we’ve collated all the information you need to help you and your practice, including:

What has changed?

As a reminder, here’s what has changed. MTD for Income Tax is replacing the current Self Assessment system for business owners and landlords in stages, depending on their incomes (not profit):

  • From April 2026 (tax year 2026/27) - all self-employed individuals and landlords with qualifying income over £50,000
  • From April 2027 (tax year 2027/28) - all self-employed individuals and landlords with qualifying income over £30,000
  • From April 2028 (tax year 2028/29) - all self-employed individuals and landlords with qualifying income over £20,000

What counts as qualifying income?

Qualifying income is the money made in a tax year from self-employment and rental properties.

Other types of income reported on a Self Assessment - like a salary (PAYE), money from a partnership, or dividends - don’t count towards this.

HMRC looks at income before expenses. They’ll use gross income (also known as turnover), which means the total amount earned before taking off any business or property expenses.

Here’s an example. If a client earns:

  • £30,000 from rental income
  • £27,000 from self-employment

their total qualifying income would be £57,000.

To comply with MTD for Income Tax, self-employed individuals and landlords need to:

  • keep records of their business income and expenses in a digital format
  • for each type of revenue (self-employed business or property), send quarterly updates of business income and expenses to HMRC
  • finalise business income by submitting a final declaration
  • pay the tax owed by 31st January of the following tax year (so no change to Self Assessment process in this area)

This isn’t just another regulatory hurdle; it’s a generational shift that demands a new approach.

Practices need to act as the navigators, guiding clients through this digital sea change. In the rest of this guide, we’ll explore the steps to take, the hurdles to consider, and the ways to set your practice up for success. First up: segmenting your clients.
