Partners and senior managers across the UK are already feeling it.

After receiving HMRC mandation letters about Making Tax Digital for Income Tax, senior leaders are asking what it means, whether it applies to them, and what they need to do next. For many firms, the letters arrived just before the middle of peak January self-assessment season, when teams are stretched to their maximum.

And MTD for Income Tax isn’t the only change; there are other regulatory requests competing for the team’s time and attention. It’s a testing time for organisational leaders, and many will be wondering how they will manage the MTD transition with so many other competing demands. 

The Making Tax Digital for Income Tax Self Assessment (MTD ITSA) rollout represents one of the most significant compliance changes HMRC has introduced in recent years.

The impact of MTD for Income Tax

The MTD for Income Tax deadline begins in April 2026, with further phases expanding the scope of the MTD ITSA rollout in subsequent years.

MTD for Income Tax represents a fundamental shift in how sole traders and landlords report their income to HMRC. From April 2026, MTD will apply to:

• Sole traders and landlords earning £50,000+
• Around 780,000 taxpayers in the first wave

Instead of one annual self-assessment return, clients in-scope will be required to:

• Keep digital records
• Submit quarterly updates to HMRC using MTD-compatible software
• Complete an end-of-period statement and final declaration

The thresholds will gradually widen:

• £30,000+ from April 2027
• £20,000+ from April 2028

The operational reality for firms

For many practices, the challenge of MTD ITSA is not the technical requirements alone, but the operational disruption it introduces across existing compliance workflows.

The task does not lie in the regulation alone; it’s the timing and volume of work it creates. Preparation for compliance will need to begin well before April. 

In reality:

• Clients need to be onboarded onto MTD-compatible software well in advance
• Processes need to be redesigned for quarterly reporting
• Teams need to be upskilled to be able to field questions and answer reassurance calls.

Many practices report a familiar pattern – for every ten clients contacted, around four typically respond with confusion or concern. Partners describe follow-up calls from clients who are unsure whether they have done something wrong, unclear about what action is required, or anxious about potential penalties. This has created an immediate spike in unplanned client communication and reassurance work.

With this unplanned activity happening during one of the busiest periods in the compliance calendar, many partners believe 2026 will be one of the most operationally disruptive years since the introduction of FRS 102.

Increasing compliance change in 2026

The introduction of MTD will not be the only change to compliance in 2026. Other changes include:

• FRS 102 lease accounting changes
• New revenue recognition rules
• Capital allowance changes

These changes will require increased data gathering from clients, additional calculations and judgement calls, and increased review time and client explanation, particularly for SMEs unfamiliar with balance-sheet leases. 

Each change will have its own learning curve, client communication burden and internal process impact. Together, they create a cumulative strain that may be difficult to manage.

The importance of automation 

The firms that stand the best chance of managing this challenge will have already automated large parts of their accounts production and corporation tax workflows. While automation by itself does not solve the many issues that MTD and the other compliance changes introduce, it serves one very important purpose – it introduces capacity at a time it is sorely needed. 

MTD is fundamentally a capacity problem.

It requires:

• More frequent reporting
• More client touchpoints
• More onboarding work
• More process discipline

Automation will not remove the work burden entirely, but it will allow leaders to manage team resources with much more sophistication and knowledge. 

For many firms, accounts production remains one of the biggest time drains in the compliance cycle. When that work is manual, fragmented or heavily spreadsheet-driven, it absorbs capacity that could otherwise be used to manage new regulatory demands. This is where compliance automation becomes a strategic decision rather than a technical one.

Where Silverfin fits 

While Silverfin software does not specifically accommodate income tax, its automated software helps firms to substantially reduce the cost and time burden of daily tasks. It does this by:

• Standardising working papers
• Automating accounts production
• Streamlining corporation tax workflows
• Reducing rework and manual effort

Studies show that firms that use Silverfin regularly cut accounts production time by up to 50%. This time saving provides teams with much-needed breathing room and flexibility. Time is a desperately needed resource in a time of flux, and particularly matters when:

• Clients are calling about MTD letters
• Teams need training on new standards
• Partners are juggling multiple regulatory deadlines at once

What firms should be doing now

Regardless of which software you use, here are practical steps firms can take now.

• Audit your current compliance workload
  Look across all obligations for 2026, not just MTD. Where is time really being spent?
• Identify your biggest capacity drains
  For many firms, accounts production is still the area with the highest manual effort and the greatest opportunity for automation.
• Don’t delay MTD conversations
  Clients receiving letters need clarity now. Even if implementation comes later, reassurance and planning can’t wait.
• Streamline where you can, protect where you can’t
  You may not be able to simplify MTD itself but you can simplify other parts of your compliance workload to make space for it.

A final thought

MTD for Income Tax is adding pressure to an already demanding compliance landscape. Acknowledging that reality rather than pretending there’s a silver bullet is the starting point.

The firms navigating this best aren’t solving everything at once. They’re creating capacity where they can, so they’re better equipped to deal with the changes they can’t avoid.
