This piece walks UK accountants and bookkeepers through the MTD ITSA £50,000 threshold now in force, does the arithmetic on what one new client is worth, and explains what ICAEW and ACCA actually allow in marketing. It is honest about which statistics on referral, retention and search volume could not be verified, and sets out plainly what technical SEO work does and does not cover.
From 6 April 2026, Making Tax Digital for Income Tax Self Assessment became mandatory for self-employed people and landlords with total qualifying income over £50,000. That threshold drops to £30,000 from 6 April 2027 and to £20,000 from April 2028, according to ICAS and Deloitte's Taxscape briefings. If you are a sole practitioner or a small firm, you already know what that means in practice: a wave of clients who have never filed quarterly in their life, ringing you in a mild panic, typing something like "accountant near me" or "MTD accountant" into Google on their phone. The question worth asking is whether they can find you when they do that, and whether what they find looks like a firm that knows what it's doing.
The penalty regime that comes with it is reportedly points-based: one point for each missed quarterly update, with four points triggering a £200 fine, according to ICAS and Avalara's 2026 summaries. I haven't verified the exact statutory wording on gov.uk myself, and there's a note in some sources that general partnerships are phased in on a different timeline to sole traders and landlords, so if a client asks you to confirm the fine print, check it directly rather than take a summary's word for it, mine included. What's solid enough to build a campaign around is the shape of it: a hard threshold, already in force, with two more drops scheduled for 2027 and 2028, and a client base that mostly doesn't know it applies to them yet.
What one new client is actually worth
Before spending anything on getting found, it's worth doing the sum on what finding one client is worth. Fee ranges vary a lot by firm and complexity, but a few figures turn up consistently across UK pricing-guide sites. Self assessment returns for employed individuals are typically quoted at £150 to £250, rising to £250 to £500 or more for self-employed people, landlords and directors, according to Sleek UK and TaxCare's 2026 pricing pages. Statutory accounts plus a CT600 for a straightforward small limited company sit around £500 to £1,500 plus VAT, per DigiAccounting and Stewart Accounting's 2026 guides, climbing to £1,500 to £3,500 for anything with multiple directors or a bookkeeping backlog. Bookkeeping retainers run £150 to £950 a month depending on transaction volume, according to Alto Accounting.
| Service | Typical UK fee range | Source |
|---|---|---|
| Self assessment (employed) | £150 to £250 | Sleek UK, 2026 |
| Self assessment (self-employed, landlord, director) | £250 to £500+ | Sleek UK / TaxCare, 2026 |
| Small company accounts + CT600 | £500 to £1,500+VAT | DigiAccounting / Stewart Accounting, 2026 |
| Bookkeeping retainer | £150 to £950/month | Alto Accounting, 2026 |
None of those figures come from an official ICAEW or ACCA fee survey. I looked. What exists is a cluster of accounting-firm and marketing-agency pricing guides quoting broadly similar ranges, so I've treated them as an indicative market picture rather than an audited statistic, and I'd say the same to a client who asked me. What I won't do is tell you how long the average client stays, or what your churn rate should be, because I couldn't find a reliable UK-specific figure for either. The numbers that circulate online (90 to 96 percent retention for "top firms") trace back to American practice-management software vendors with no named methodology and no date. If someone quotes you that stat to sell you something, ask where it's from.
Even without a retention figure, the arithmetic holds up on its own. A single self-employed self assessment client at £350 a year, or a bookkeeping client at £400 a month, easily covers a modest monthly spend on getting found, for as long as that client stays with you. You don't need to know the average tenure to know that one client found through search, rather than lost to a competitor who ranks above you, is worth having.
Where your Google Business Profile does more work than your website
I can't give you a verified number for how many people search "accountant near me" each month. The figures floating around online are SEO-agency estimates pulled from keyword tools, not independently audited data, so I'm not going to hand you one and pretend it's solid. What isn't in dispute is how Google displays that kind of search: for a local, "who's near me" query, Google shows the map pack, built from Google Business Profile listings, above any organic website result. If your profile has a wrong opening time, no reviews, or a category that says "Accountant" when a prospective client searched "bookkeeper", that's costing you before anyone reaches your website at all.
This matters because it changes where effort should go first. A beautifully built website does nothing for a search where Google never shows it. For firms that want local, face-to-face clients, the profile usually needs sorting before the site does. Where the website earns its keep is everywhere else: in the searches that aren't hyper-local, in whatever a client's AI assistant pulls up when they ask it to find or check an accountant, and in giving the map pack listing somewhere credible to link to.
What the Codes of Ethics actually let you do
If you're ICAEW-regulated, the rule that governs marketing is R115.2 of the Code of Ethics: a professional accountant "shall not bring the profession into disrepute" when marketing, and the accompanying guidance requires honesty and truthfulness, with no exaggerated claims about services or experience, and no disparaging references or unsubstantiated comparisons to the work of others. ICAEW's own illustrative example is blunt: it would not be acceptable to say "we provide a better service than X firm in Manchester," even if it happens to be true, because it names and disparages a competitor. R115.3 separately bars marketing that amounts to harassment of a potential client, though the guidance is clear that one or two follow-up mailshots over a reasonable period wouldn't normally cross that line. Worth flagging: ICAEW refreshes the Code of Ethics annually, and the edition that took effect on 1 July 2026 is the current one, so if your compliance officer wants the exact wording, that's the version to check.
ACCA members work under Section 3 of the ACCA Rulebook, which adopts the IESBA International Code of Ethics. The general principle is that members may advertise their services in any way they see fit, provided the medium doesn't reflect adversely on the member, ACCA, or the profession. I'll be straight about a gap here: I couldn't find the exact ACCA or IESBA wording on cold-calling or approaching a competitor's clients, beyond that general disrepute principle, so I'm not going to invent specifics. If that question matters to your practice, it's worth a direct look at the ACCA Rulebook rather than taking anyone's word for it, mine included.
None of this stops you appearing higher in search results, having a clear website, or publishing accurate information about your services. It stops you claiming to be the best, or naming a rival unfavourably. That's a rule I build around by default, not something to work round.
How clients actually find you, and why I won't quote you a stat
There's a well-worn claim doing the rounds that 58 percent of small businesses find their accountant through referral. I traced it. It comes from a 2012 Sage survey of North American businesses, which makes it over a decade old, from the wrong country, and not really about the point it's usually used to make. I found a handful of other figures too, from SEO agencies selling services to accountants, claiming things like "62 percent of UK firms get over half their clients from referral" or "87 percent of accountants report inbound enquiries from organic search." None of them come with a named methodology or a date I could check, so I'm leaving them out rather than repeating them with a straight face.
What I'll say instead, because it's true without needing a statistic to prop it up: referral is usually still where a small accountancy practice starts, supplemented by the professional-body directories and, increasingly, by whatever a prospective client's search engine or AI assistant surfaces when word of mouth runs out. That last part is the bit growing fastest and the bit most firms haven't touched.
The directory that doesn't quite exist for accountants
For financial advisers, Unbiased.co.uk is the dominant matchmaking platform, and it does cover accountants as one category among several, claiming over 27,000 listed professionals. But its brand and traffic are built around IFAs, not accountants specifically. On the professional-body side, ICAEW runs its own Find a Chartered Accountant directory, listing over 21,000 firms, and ACCA runs an equivalent. Both are free, unranked, and exist to verify membership rather than to compete for clicks. The upshot is that there's no single commercial platform doing for accountants what Rightmove does for estate agents. That's not a small thing: it means your own site and your own Google presence carry more of the weight of being found than they might in a sector with one obvious marketplace to be listed on.
What the technical work actually does, and what it doesn't
What I do is the technical side of being found, handled as one job. That's site structure and crawlability, so search engines and AI crawlers can actually read and index your pages properly. Structured data, so a search engine or an AI assistant summarising "accountants in Dulwich" can correctly pull your services, location and opening hours rather than guessing. Metadata that describes each page accurately. Making sure AI crawlers like GPTBot, ClaudeBot and PerplexityBot aren't accidentally blocked, since being invisible to those means being invisible to anyone asking an AI assistant to recommend an accountant. And then keeping all of that correct every month, because sites drift, HMRC pages change, and a service page you wrote in 2024 can quietly go stale.
It costs £100 a month, no lock-in, first month free. It doesn't include writing your content, running paid ads, or building links. You deal with me directly rather than an account manager, and I'd rather be straight about the edges of what I do than sell you a package that pretends to cover everything. And I won't promise you a ranking, a number of new clients, or a mention in an AI answer. What I can promise is that the technical groundwork gives you a better chance of showing up correctly when someone, or something, goes looking.
What I would do about it, and what it costs
And consider what a single miss actually costs here. A small company client is worth several thousand pounds across the years they stay with you. If your site does not tell Google and the AI assistants precisely what you do, who you do it for and where, that business finds another firm. There is no bounced enquiry to review, no lost pitch to learn from. The work simply goes somewhere else, quietly, and the only sign is a pipeline that stays thinner than it should.
A small company client on a twelve hundred pound annual fee, kept for the seven years that is normal in this profession, is worth several thousand pounds. One extra client a year covers this many times over. That is the arithmetic, and it is the most favourable of any trade I work with.
Here is what I would put in place. Service and fee information structured so that a search engine, and an AI assistant asked to recommend an accountant nearby, can read exactly what you do, who for, and where. Accreditation and professional body membership stated in a machine readable form rather than sitting in an image. The technical foundations checked so nothing is quietly stopping you being indexed. Then maintained monthly as your services and deadlines change.
That is £100 a month. First month free, no contract, and no account manager between you and the work. If you want to know what your firm's site currently tells a machine about you, send me the address and I will tell you, or get started here.
