From April 2026, hundreds of thousands of sole traders and landlords are being forced by law to change how they handle their tax. It is the largest involuntary wave of accountancy demand in years. Most firms are responding by frightening the clients they already have, instead of marketing to the ones now looking.
Key facts
The short version
- MTD is the biggest forced wave of new accountancy demand in a decade.
- Most firms are emailing existing clients scary “are you ready?” warnings, which is admin, not marketing.
- The opportunity is the people who have never had an accountant and suddenly need one.
- Fear sells software. Calm, clear reassurance sells your firm.
- The firm that becomes the obvious, plain-English answer to “what do I do about MTD?” wins the decade, not just the deadline.

The uncomfortable argument
Once in a while the government hands an entire profession a queue of new customers. Making Tax Digital for Income Tax is exactly that. From April 2026, around 864,000 sole traders and landlords with income over £50,000 must keep digital records and file quarterly. Many have never used an accountant, and a lot of them are quietly panicking.
So what is the profession doing with this gift? Mostly, sending its existing clients stern emails about deadlines and penalties. That is not marketing. That is housekeeping dressed as urgency, and it wins not a single new client.
The wave most firms are facing the wrong way
This is not a normal sales cycle where you persuade someone they have a problem. The problem has been legislated. HMRC is writing to people. The press is running scare stories. Demand is being manufactured for you.
And it grows. From April 2027 the threshold drops to £30,000, and from April 2028 to £20,000, pulling in hundreds of thousands more each year. This is not a deadline to survive. It is a multi-year pipeline to own, if you point your marketing at the people arriving rather than the people already sitting in your client list.
What MTD actually changes
The detail matters, because clarity about it is the product. From April 2026, those in scope must keep digital records, send HMRC four quarterly updates of income and expenses, and submit a final declaration that replaces the familiar single self assessment return.
For someone who has always done a once-a-year tax return on a spreadsheet, that is four times the contact, new software, and a real fear of getting it wrong. They are not buying compliance. They are buying the removal of that fear. Whoever explains it most simply earns the trust, and usually the engagement.
Fear is the wrong marketing
The default tone across the profession right now is alarm. Deadlines in bold. Penalty figures. “Don’t get caught out.” It feels responsible, and it is the wrong instrument.
Fear makes people freeze or grab the cheapest software to make the worry stop. It does not make them trust a firm. The buyer in this wave is already scared. They are not looking for another voice raising the temperature. They are looking for the calm one that lowers it. Reassurance, not alarm, is what converts here.
The maths of one MTD client
Firms underrate this wave because they price it as a one-off job. It is not. The numbers are illustrative, but the shape is the point.
| One new MTD client | Seen as a one-off | Seen as a relationship |
|---|---|---|
| First-year fee | £600 | £600 |
| Kept for five years | Not considered | £3,000+ |
| Advisory and referrals over time | £0 | Often the larger half |
| True value of winning them now | £600 | Thousands, plus the people they refer |
A scared sole trader who finds a calm, clear firm in 2026 does not leave in 2027. Winning them during the wave is the cheapest client acquisition you will see for years, because the motivation is already there.
Who you should actually be talking to
Your existing clients need a clear process and a reassuring email. That is service, and it matters. But it is not where the growth is.
The growth is the unrepresented: the landlord with three properties who has muddled through alone, the sole trader over the threshold who has never needed help before, the person who just got an HMRC letter and typed their panic into Google or an AI assistant. None of them are on your list yet. All of them are searching right now.
How to market into the wave
The move is simple and almost nobody is doing it well: become the clearest explainer of MTD for a specific kind of person. Plain-English guides for landlords. A short answer to “do I actually need an accountant for MTD?” An honest page on what it costs and what you do. The point is to be findable and reassuring at the exact moment someone is frightened and searching, including in AI search, which is covered in will AI recommend your accountancy firm. You can even hand prospects a clear primer like our guide to Making Tax Digital for sole traders, and let the clarity do the selling.

A simple, slightly uncomfortable audit
Five questions. Answer them honestly.
- If a landlord searches “MTD help” today, does anything you have published appear, or only your rivals and the software firms?
- Is your MTD messaging built to reassure a frightened newcomer, or to remind existing clients of a deadline?
- Could a stranger find out what you charge to handle MTD without booking a call?
- Have you created anything aimed at people who do not yet have an accountant, or only at people who already do?
- Are you treating MTD as a 2026 deadline, or as a pipeline that widens through 2027 and 2028?
If those sting, that is the gap between weathering MTD and growing on it.
The takeaway
MTD is the rarest thing in marketing: demand you did not have to create. Hundreds of thousands of people are being told by law that they need what you sell, and the number grows for three years.
Stop emailing your existing clients warnings and start being the calm, clear, findable answer for the people who are newly afraid. Reassure, do not alarm. Win them now, keep them for years. The firms that treat MTD as a marketing opportunity, not a compliance chore, will look back on 2026 as the year they grew.
A note on the numbers. The 864,000 figure and the April 2026, 2027 and 2028 thresholds are based on HMRC and UK tax-profession reporting on Making Tax Digital for Income Tax as of June 2026. The client-value table is illustrative, written to show the shape of lifetime value, not a claim about any specific firm or fee. This is a Whito opinion piece, not tax or financial advice.
