Under MTD, client behaviour drives the work. Has your pricing caught up?
Quarterly submissions are only part of the workload under MTD for Income Tax. Discover why firms need to account for record management, client support, reviews, and ongoing oversight when reviewing their pricing strategies.
Under MTD for Income Tax, the work does not come only from the submission.
It comes from your client.
If you’ve already started rethinking your pricing under MTD, this is the next layer: understanding what actually drives the work behind each quarterly obligation.
Before MTD, work was often tied to a specific moment. Prepare. File. Close. Once the return was submitted, the engagement largely paused.
MTD changes that rhythm, and with it, the economics of your practice. Quarterly filings are visible, but the oversight behind them is not.
From the outside, MTD can look like four submissions and a button press. From the inside, it can become a continuous cycle of review, correction, chasing and risk management.
The client sees a confirmation screen, but your team carries the consequences if something is wrong behind it.
That gap, between what clients see and what your practice carries, is where pricing can break.

Key takeaways
- Under MTD for Income Tax, client behaviour can create more work than the submission itself.
- Record quality, responsiveness and software confidence can affect how much time your team spends reviewing, correcting and chasing information.
- Turnover alone may not be enough to judge client complexity under MTD.
- Pricing should reflect the responsibility your firm carries between quarterly deadlines, not just the act of filing.
- Engagement letters may need to clarify responsibilities, turnaround expectations, scope boundaries and what support sits outside the agreed service.
Why is the cost in client behaviour, not the submission?
Work that accumulates under MTD for Income Tax will not always arrive as a single, identifiable task.
It may arrive as a mid-quarter clean-up that was not billed, records that need chasing before submission, or data that is technically complete but not commercially usable.
Individually, these tasks can feel like admin.
Collectively, they can erode your margin.
Hidden Hours research from Sage suggests many firms are already absorbing operational support and follow-up work informally before MTD even began.
Quarterly reporting increases the frequency and visibility of those pressures.
Hannah Miller, Director of Chipperfield Accounting, described this kind of compounding at ICAEW’s MTD Live in February 2026.
Her firm offered spreadsheets as an alternative workflow, and more clients accepted than anticipated.
That multiplied review paths and fragmented processes across the portfolio.
Optionality can feel client-friendly. Operationally, it can create volatility.
Rebecca Benneyworth, tax consultant and MTD Working Group member since 2016, outlined another practical cost at the same event: bridging submissions take considerably longer because every box must be relayed manually.
That time does not disappear. If it is not priced, it erodes margin.
The real risk under MTD is unpredictability.
The same quarterly obligation can create very different workloads depending on how clients maintain records, respond to requests and use software.
If your most straightforward and most demanding clients pay the same fee, your pricing model may be working against you.
Why is behaviour a more useful pricing guide than turnover?
A sole trader with modest income but chaotic records can consume more oversight time than a larger business with clean, timely data.
Turnover used to be a common signal of complexity. Under MTD, behaviour can be a stronger signal of the work required.
Rebecca Benneyworth was direct at MTD Live about what software adoption can look like without proper supervision.
Records that were manageable on paper can become harder to work with once clients use software unsupervised.
Issues can include:
- duplicated transactions
- receipts and payments both posted
- personal and business finances mixed
The behavioural overhead does not shrink just because the tool changes.
A more useful lens has two dimensions:
- how clean the records are when they reach you
- how confident the client is with their software
Plot clients across those two axes, and the variation in effort becomes easier to see, explain and price.
E-Book: MTD for Income Tax—The final countdown playbook for practices
Accountants and bookkeepers still have time to create a repeatable plan for MTD success. This e-Book explains how, via a fast-track mindset, and a 5-phase countdown to April 2026—and beyond.
How should practices price the responsibility, not just the filing?
Repricing for MTD does not need to be complex.
Start by clarifying what you are actually doing.
A base compliance layer could cover quarterly updates and the annual return.
Every client pays for that core service. Everything above that should reflect behaviour: how clean the data is, how self-sufficient the client is, and how much risk your firm carries between filings.
That includes the operational time spent reviewing incomplete records, resolving inconsistencies and maintaining oversight between quarterly deadlines.
Nikhil Sangani, chartered accountant at Sage & Co, an independent accounting firm not affiliated with Sage, framed the principle simply at MTD Live: same process as last year, same price; correcting incorrect entries, probably more expensive.
That is not a complex methodology. It is a direct link between behaviour and scope.
Hannah Miller takes it further, tying monthly billing to a behavioural condition: data delivered within fourteen days of quarter end as a condition of the fee structure.
That makes the arrangement a two-way commitment rather than a unilateral charge, and gives your firm a documented basis for scope conversations if the terms are not met.
Once you can see how behaviour drives the work, the next step is turning that into something you can apply consistently.

What should you discuss with clients before the bill arrives?
Repricing friction usually comes from framing.
If you describe MTD as four extra submissions, clients may see it as admin.
If you describe it as ongoing oversight and responsibility, the conversation changes.
Treat the repricing discussion like a discovery call. Understand:
- how the client wants to work under MTD
- how confident they are in keeping records current
- whether they want ongoing support between quarters
- what level of oversight your firm is expected to provide
- what should happen if records are late, incomplete or inaccurate
Listen first, then give your recommendation.
When clients feel heard, a fee change can land as a tailored solution rather than an arbitrary increase.
Consider adopting value pricing for accountants to better reflect the expertise you provide.
Whatever you agree, formalise it. If your engagement letters still describe a static annual service, they may not reflect the ongoing relationship MTD for Income Tax demands.
Document what oversight includes, what triggers a scope change, and what sits outside the engagement.
It is easier to hold a pricing boundary when your client has agreed to it in writing.
What this means for your practice
Pricing under MTD is not only a commercial decision.
It is also a signal about how your firm values its expertise, time and responsibility.
The firms that prepare well will not only ask, “What do we file?”
They will ask, “What do we carry, review, correct and manage between filings?”
If you’re switching your practice from self assessment, now is the time to consider an MTD for Income Tax operational reset.
If your pricing needs to reflect client behaviour, the next step is to assess where that behaviour is already creating hidden work across your firm.
Use this checklist: Before you price for MTD for Income Tax, answer these questions.

Frequently asked questions about MTD client behaviour and pricing
Client behaviour affects how much review, correction, chasing and oversight work accumulates between quarterly submissions.
Poor record quality, late responses and low software confidence can all increase the amount of work your team carries.
Two clients can have similar turnover but create very different workloads.
Record quality, responsiveness, bookkeeping habits and software confidence can all affect how much operational support each client needs.
Many firms are reviewing pricing models because MTD creates more continuous operational work throughout the year, rather than one annual filing cycle.
Pricing should reflect the responsibility and oversight involved, not only the submission itself.

Engagement letters may need to clarify quarterly responsibilities, turnaround expectations, scope boundaries and what support sits outside the agreed service.
This helps both the practice and the client understand:
– what is included,
– what is not included,
– and what may trigger a scope change.
Software can reduce manual processing, but it does not remove the need for good records and clear client processes.
Poor record quality, inconsistent bookkeeping and behavioural issues can still create significant review and correction work.
Understanding what is an MTD digital link can help clarify software requirements.
A practical starting point is to look at two things:
– how clean the client’s records are when they reach you,
– and how confident the client is using their software.
Clients with weaker records or lower software confidence may need more support between quarterly deadlines.
The main risk is that extra review, correction, chasing and oversight work becomes absorbed informally.
If that work is not reflected in scope or pricing, it can erode margin and make the service harder to deliver consistently.
