The Bigger Picture: A Margin Problem Hidden in Plain Sight

Making Tax Digital for Income Tax went live in April 2026, bringing the first cohort of sole traders and landlords — those earning above £50,000 — into quarterly digital reporting. More than 780,000 businesses entered the new regime at launch. The £30,000 threshold drops in 2027, widening the scope significantly.

The compliance mechanics are broadly understood. What is less openly discussed is the pricing structure that sits beneath them. Most accounting firms are currently absorbing four quarterly submission cycles per client — with the associated preparation, client communication, and advisory conversations — at fee levels calibrated for an annual engagement. The pricing logic was built for a different model.

Diplexcito is candid about the result: “I suspect in a lot of cases, this MTD work is at a lower margin.” This is the kind of observation that senior partners instinctively recognise and instinctively avoid saying out loud. But the numbers do not resolve themselves by being ignored. Every quarter that passes without a pricing review is a quarter of margin that will not return.

What Independent Accountants Need to Know

For independent accounting firms and regional accounting practices, this margin compression bites harder than it does at national firms. Smaller practices cannot absorb inefficiency across thousands of clients. Every engagement that is mispriced drains capacity that could otherwise be directed toward higher-value work.

There is also a client relationship dimension that deserves attention. Clients entering the quarterly MTD cadence are arriving more financially engaged than they have ever been. They are asking forward-looking questions about tax positions and cash flow. They are beginning to expect the kind of insight-led conversation that, at many practices, has historically been reserved for larger business clients.

The firms pricing quarterly MTD work as though it were simply a compressed annual return are setting themselves up to deliver less than clients now expect, at a rate that does not cover the cost of delivering it well. That is a formula for both margin erosion and client attrition — two outcomes no practice can afford to run simultaneously.

For high street accountants managing dozens of self-employed clients, the arithmetic is especially sharp. Four touchpoints a year for fifty clients means two hundred client-facing interactions that were not there before April 2026. If each one is costed like a self-assessment return, the practice is likely under-recovering on most of them.

What Forward-Thinking Practices Are Already Doing

The practices getting this right have made a deliberate decision to restructure quarterly MTD work as advisory delivery, not compliance administration. In practical terms, that involves three clear moves.

Repricing the quarterly touchpoint to reflect actual cost and value. This means conducting a genuine time-cost analysis of MTD work — not extrapolating from annual return pricing — and rebuilding service packages around a quarterly engagement model. Firms that have done this analysis consistently find the required fee increase is smaller than they feared, and clients accept it more readily than expected when it is framed around value rather than cost.

Reframing each quarterly deadline as a forward-looking advisory session. Rather than filing the quarter and moving on, forward-thinking firms are using the mandated touchpoint as a structured moment for financial review and planning conversation. What does the next quarter look like? Are there decisions the client should be making now? Is their tax position likely to shift? This reframing takes the same compliance obligation and generates advisory revenue from it.

Reviewing the client base through a quarterly-engagement lens. When the conversation frequency increases from one to four times a year, clients who appeared low-value on an annual-return basis sometimes reveal significant advisory potential. Firms conducting this review are uncovering upsell opportunities across clients they had assumed were fixed.

How This Connects to Accounting Firm Growth

The underappreciated commercial opportunity inside Making Tax Digital is this: it creates a government-mandated, structured reason to speak with each client four times a year. No marketing campaign, however well-funded, gives you that level of guaranteed access to a client’s financial thinking.

For practices that want to grow, that access is the foundation of accounting firm growth. Clients who hear from their accountant quarterly — who receive structured insight and planning input rather than a bill and a filed return — are less likely to leave and more likely to refer. Word-of-mouth referrals remain the primary source of new business for most independent practices, and they are driven by the quality of the ongoing client relationship. MTD, repriced and reframed, creates the conditions for that quality relationship at scale.

The firms that treat MTD as a compliance task to be processed efficiently will find 2027 significantly more difficult when the £30,000 threshold expansion widens the scope of the regime. The firms that treat it as a catalyst for repricing and relationship deepening will find themselves with a more valuable, more defensible client base — and a structural advantage over practices that have not made that pivot.

Independent accounting practices that want to build a growth model around MTD — rather than simply absorb its margin pressure — rarely get there alone.
