Accountant AI receptionist: covering the January rush without giving tax advice

The last fortnight of January at a small accountancy practice has a sound of its own. The phone rings while you're reconciling a landlord's rent schedule, again while you're on hold to the agent dedicated line, and again while you're explaining to a client why their payment on account is so high. Half the calls are from people who aren't clients yet and need a return filed by the 31st. If nobody answers, they ring the next practice on the list. An accountant AI receptionist answers those calls, takes the details of the late filers, books the discovery calls and gives out your published fees. What it never does is answer a tax question, because a wrong "yes, you can claim that" is your problem, not the AI's.

This page is for sole practitioners, two- and three-partner firms and bookkeeping practices: the ones that do self-assessment, small company accounts, VAT, payroll and bookkeeping for local businesses. It covers the calls an accountancy practice gets through the year, what an AI receptionist can safely handle, what it must hand to a qualified person, the anti-money-laundering checks that stay with your staff, and the numbers.

The calls an accountancy practice gets

Accountants get fewer calls than a dental surgery or a plumber, but they come in much sharper peaks, and each new-client call is worth years of fees.

New client enquiries

These come in three main kinds:

• Self-assessment one-offs. A newly self-employed tradesperson, a landlord with their first rental, someone with a side income from a marketplace, a higher earner caught by the High Income Child Benefit Charge. Most of them want a price and a yes.
• Small company work. A director who has just incorporated, or one unhappy with their current accountant, asking about year-end accounts, the corporation tax return, payroll for two staff and VAT.
• Bookkeeping and payroll. Businesses that want someone to keep Xero or QuickBooks up to date, run monthly payroll and do the VAT returns.

All three ask the same opening questions: do you do this kind of work, how much does it cost, and can you start in time?

Existing clients

Clients ring to ask whether their return has been filed, what they owe and when, whether you've had their bank statements, and what a letter from HMRC means. They send photos of receipts on WhatsApp at 11pm. They want to book their annual review. An AI receptionist can't look at their file, because Klugon doesn't connect to your practice software, but it can take an accurate message and flag it, book the review and answer the practical questions about how to send documents.

Calls from HMRC, Companies House and other firms

Previous accountants replying to a professional clearance request, HMRC officers, a client's mortgage broker asking for an accountant's reference, a solicitor on a probate matter. These callers want a named person. The assistant takes the message, confirms nothing about any client and flags it.

When the phone rings

Mornings bring clients who opened a brown envelope from HMRC over breakfast. Lunchtimes bring business owners calling between jobs. Late evenings and weekends bring the self-employed, who do their admin when the work stops, and they're exactly the people least likely to leave a voicemail. Self-employed clients also tend to message rather than ring, which is why WhatsApp and website chat matter more for an accountant than for many professions.

The self-assessment deadline peak

The year has a shape every practice knows, and it's set by HMRC's calendar. According to GOV.UK's Self Assessment deadlines page, the online return and payment for the 2025 to 2026 tax year are due by 11:59pm on 31 January 2027, paper returns by 31 October 2026, and anyone new to Self Assessment needs to register by 5 October 2026. The second payment on account is due on 31 July.

How much of that lands on the deadline is easy to underestimate. HMRC reported in February 2026 that 11.48 million people filed their Self Assessment return by 31 January 2026, out of about 12.03 million expected. It recorded 27,456 returns filed in the final hour of deadline day alone. A good share of the people filing late come to an accountant in January for the first time, and they ring after work, at weekends and on the 30th.

The rest of the year has smaller peaks:

• April, when the new tax year starts and organised clients want to get their return in early.
• July, around the second payment on account, with clients asking why it's so much and whether they can reduce it.
• VAT quarter ends, when bookkeeping clients send in a month of receipts at once.
• The months before company filing deadlines, often December for a March year end, because private company accounts are due at Companies House nine months after the year end.
• The Making Tax Digital quarters. HMRC's guidance on signing up for Making Tax Digital for Income Tax says sole traders and landlords with qualifying income over £50,000 must use it from 6 April 2026, with lower thresholds following in later years. That brings quarterly updates, a new set of questions from clients, and new clients looking for an accountant who will handle it for them.

What an accountant AI receptionist handles

The useful work is the admin that crowds out billable time in a small practice.

Taking new-client enquiries properly

For every new enquiry, the assistant asks the same questions you'd want answered before a discovery call:

1. Full name, phone number and email.
2. Whether they're a sole trader, a landlord, a company director, a partnership or employed with extra income.
3. For a company, the company name, so your team can look it up on Companies House before calling.
4. What they need: a self-assessment return, year-end accounts, VAT, payroll, bookkeeping or a mix.
5. Which tax year or year end the work is for, and whether anything is already late.
6. Whether they have a current accountant, which affects professional clearance.
7. Which software they use, if any, such as Xero, QuickBooks, FreeAgent or Sage.
8. How they found you.

It records the answers as a lead, then either books a discovery call or tells them when to expect a call back. If anything is overdue, it flags the enquiry so a person sees it first.

Booking discovery calls, onboarding meetings and annual reviews

Set each meeting type up as a service in Klugon's built-in calendar, with its own length and the people who offer it:

• a free 15-minute discovery call for new enquiries;
• a 45-minute onboarding meeting, in the office or on video;
• a 30-minute annual review for existing clients;
• a 60-minute tax planning meeting, which is a paid service with a qualified person.

Block out the days you won't take meetings, such as the last week of January, as closed dates. Set a minimum notice so nobody books an onboarding meeting for the next morning before your team has had a chance to look them up.

The assistant gives the booking reference in the conversation. It doesn't send confirmation emails, text messages or reminders, so if your practice sends a welcome email, keep sending it yourself. In chat and on WhatsApp it can move a booking. On the phone it can book and cancel, but not reschedule, so a client who rings to move their review is flagged for your team. If your team works from Outlook or Google Calendar, the assistant can check busy times there and add events after you connect them on the Business plan. It's a tool the assistant uses, not a full two-way sync.

Answering the practical questions

Give the assistant your own information and it answers from it, the same way every time:

• the services you offer and the ones you don't, such as R&D tax credits, trusts or overseas tax, with who you refer to;
• your fixed-fee packages, such as a sole trader return, a landlord return with one property, or small company accounts and corporation tax return;
• the date by which you need records to guarantee a January filing;
• how to send documents: your client portal, a secure upload link or the office address, and what not to send by WhatsApp;
• the documents a new client needs for onboarding and identity checks, from your own list;
• office hours, parking and whether you meet clients in person;
• which accounting software you support.

On every question, it answers from what you've written. If a client asks something that's in neither your knowledge nor your instructions, it says a person will get back to them.

The tax advisor chatbot question

Firms searching for a tax advisor chatbot are often hoping for something that answers clients' tax questions overnight. That's the part to resist. A chatbot on an accountant's website should be an excellent receptionist and nothing more: it books, quotes published fees, collects details and explains how the practice works. Everything that turns on a client's own figures goes to a qualified person. That's not just caution. It's what your professional body's rules and your indemnity insurer will expect.

Covering every channel the self-employed actually use

Clients reach accountants by phone, but also by WhatsApp and the website. The website chat widget is a script tag pasted into your site. WhatsApp connects through Meta's WhatsApp Business setup. Everything lands in one inbox, phone calls included, so a client who rings on Monday and messages on Thursday shows up in the same place. You can reply to WhatsApp messages from the inbox within Meta's 24-hour window. Phone and website chat conversations can't be replied to from the inbox, so you call those back.

What it must hand to a qualified person

The rule for an accountancy practice is simple. The assistant gives no tax advice and makes no statements about any client's affairs. The work is in recognising what counts.

What counts as tax advice on the phone

Clients rarely ask for "tax advice". They ask quick, practical questions:

• "Can I claim my van?"
• "Is my phone bill allowable?"
• "Do I need to register for VAT?"
• "Should I be a limited company?"
• "How much should I put aside for tax?"
• "Can I pay myself in dividends instead?"
• "Do I need to do Making Tax Digital?"
• "Will I get a penalty if I'm late?"

Every one of these depends on facts the assistant doesn't have and judgement it mustn't exercise. Every one gets the same kind of answer: "That's one for one of our accountants. I can book you a call, or take your details so they can come back to you." Write that wording into the instructions with these examples, then test it with variations of your own.

Penalty questions deserve a mention of their own. In late January, the assistant will be asked "will I be fined?" dozens of times. It should not say yes, no or how much. It should take the details and get the person booked in.

HMRC letters, enquiries and disputes

A client who has had an HMRC compliance check letter, a penalty notice they want to appeal, or a letter about undeclared income needs a person quickly. The assistant takes the client's name, what the letter says it's about and any date on it, and flags the conversation as urgent. It never tells them what the letter means or what to do.

Suspected scams

Clients often ring their accountant because they've had a call, text or email claiming to be from HMRC. The assistant must not say whether it's genuine. It can give the practice's standard line, which you write, such as "Please don't reply or click any links. One of the team will call you back today." Then it flags the conversation.

Requests about another person

A spouse calling about their partner's return, an adult child calling about a parent's affairs, a director asking about a fellow director's loan account. The assistant confirms nothing and discusses nothing about anyone except the person it's talking to, and even then only takes a message.

Complaints and fee disputes

A client unhappy with a bill or a missed deadline is flagged to a partner, with the details taken calmly and your complaints procedure quoted from your knowledge. The assistant doesn't discuss the fee or admit anything on the practice's behalf.

What "hand over" means with Klugon

Klugon can't transfer a call to a person. When the assistant hands over, it marks the conversation "Needs a person" in your inbox and notifies Slack or Zapier if you've connected them. The caller is told someone will get back to them. In January, decide who watches those notifications and when, because a flagged conversation nobody sees is just a slower voicemail. The assistant isn't paused after a handover, so it will keep answering the client's other practical questions until a person steps in.

Sample conversations

These are samples written for this page. The practices and people are made up, and on a real line the AI's voice is AI-generated.

Sample phone call: a late filer on 29 January

A sample call. Ashcombe Tax & Accounts, a two-partner practice in Norwich, is made up.

The fee and the records cut-off are the practice's own January rules, written into the knowledge base. The assistant asked for the UTR status because it changes what the accountant can do in two days. It declined the van question and the penalty question without hinting at an answer. And it told Megan not to send documents until she had the secure link, which is the practice's rule for new clients.

Sample WhatsApp: an existing client with a tax question

A sample WhatsApp conversation. Kittering Lane Accountants, a sole practitioner in Derby, is made up.

The assistant knew the practice's rule on included planning calls because it was in the knowledge base. It couldn't confirm the receipts, so it said so plainly and flagged the question. Joanne can reply to Raj on WhatsApp from the inbox in the morning, because it's within Meta's 24-hour window.

Sample website chat: a limited company switching accountant

A sample website chat. Calder & Mott Chartered Accountants in Halifax is made up.

The assistant described professional clearance and identity checks in the practice's own words and didn't try to carry them out. It also didn't ask for documents, because your onboarding process does that securely, and a chat window isn't the place.

Setting up an AI receptionist at an accountancy practice

Plan to set it up in the quieter part of the year, such as the late summer or early autumn, so it's settled by November.

A setup checklist for accountants

1. List your services and your exclusions. Say who you refer to for anything you don't do.
2. Write your fixed fees exactly as you publish them, with what's included, what isn't and whether VAT is on top.
3. Write your January rules: the last date you'll take a new client, the records cut-off and any deadline-week surcharge.
4. Write the new-client questions in the order you want them asked.
5. Write the no-tax-advice instruction with the example questions above, plus your own.
6. Write the onboarding document list from your AML procedures, so the assistant can tell people what to have ready, but never ask for copies.
7. Write the scam line and the HMRC-letter handover wording.
8. Set up meeting types as services, with lengths and the people who offer each, and block out closed dates in the last week of January.
9. Write a greeting that says it's an AI assistant. Klugon's default greeting doesn't say so.
10. Connect Slack or Zapier for handovers and new leads, and agree who checks them during the January peak.
11. Test it with a colleague playing the awkward clients: the late filer, the "can I claim this?" client and the spouse.

Keeping your practice number

Keep your existing number and forward calls to a Klugon number: all calls, unanswered calls only, or out of hours only. The call forwarding guide walks through each. Phone numbers become available when the 7-day trial ends. During the trial, you test the assistant in the browser. Porting a number isn't supported, but a practice on a SIP phone system can point a SIP trunk at Klugon on the Business plan.

Working alongside your practice software

Klugon doesn't connect to Xero Practice Manager, Karbon, Senta, BrightManager, TaxCalc, IRIS or CCH, and it can't see your clients' records in Xero, QuickBooks or FreeAgent. It's the front desk. New enquiries arrive as leads in Klugon, and your team sets the client up in your own system once you've agreed to act. If you use HubSpot, Zoho, Salesforce or Pipedrive for new business, the assistant can send leads there, though not automatically for every lead. A simpler route for many practices is to post every new lead into a Slack channel with the Slack integration.

What it costs

Klugon's prices are in US dollars. The voice product is $99 a month on Starter (1,000 minutes), $299 on Business (3,600 minutes) and $499 on Scale (6,000 minutes), and yearly billing is 20% less. Each phone number is $9 a month. Minutes beyond the allowance cost $15 per started 100. Website chat starts at $49 a month and the social product, which covers WhatsApp, at $79. The full list is on the pricing page. The examples below use stated assumptions.

A worked example: a two-partner practice through the year

Assumptions, which you should replace with your own:

• The assistant answers calls the team doesn't pick up, plus everything after 17:30 and at weekends.
• From February to November, about 4 calls a day reach it, averaging 3 minutes, over 22 days: 4 × 3 × 22 = 264 minutes a month.
• In December, that doubles to around 530 minutes.
• In January, about 18 calls a day reach it, averaging 4 minutes because new-client intake takes longer, over 26 days including weekends: 18 × 4 × 26 = 1,872 minutes.

On Starter, the quiet months cost $99 + $9 = $108. January is 872 minutes over the allowance, which is 9 started blocks of 100 at $15, so January costs $108 + $135 = $243. Over a year, that's about $1,431.

If you want Slack alerts and a calendar connection, you'll need Business: $299 + $9 = $308 a month, or $248 on yearly billing. Business's 3,600 minutes absorb January comfortably.

Against a temporary receptionist for January

Many practices bring in temporary help for the last three weeks of January. At the National Living Wage of £12.71 an hour from April 2026, 30 hours a week for three weeks is about £1,144 in pay before agency fees or employer costs, and that cover stops at 17:30 on weekdays. The late filers ring in the evening. An assistant covers the evenings and weekends a temp doesn't, and it's still there for the July payment-on-account calls.

Against a telephone answering service

An answering service takes a message and passes it on, and some can book into an online diary. Compared with an AI receptionist, it gives you a person, which is better for upset clients. It doesn't usually quote your fees or know your January cut-off. Per-call or per-minute pricing also rises exactly when you're busiest. Our Moneypenny comparison goes through the trade-offs in more depth.

What one new client is worth

Say the practice misses 8 new-client enquiries in January and 4 more across the rest of the year. Half would have signed up. A self-assessment client stays an average of five years at £350 a year, and a company client at £1,800 a year. If four were self-assessment and two were companies, that's £7,000 a year in recurring fees, or about £35,000 over five years. Your own numbers will differ, so run them with your own retention and fees. If you rarely miss calls, the case is weaker.

Compliance: AML, professional standards and client data

This section is a starting point for your own compliance review, not advice.

Anti-money-laundering ID checks are done by staff

Accountancy service providers are covered by the Money Laundering Regulations. If you're a member of a professional body such as ICAEW, ACCA, AAT, CIOT or ATT, that body is usually your supervisor. Otherwise, HMRC's guidance on who needs to register for money laundering supervision says you must register with HMRC. Either way, customer due diligence happens before you act.

An AI receptionist should not take part in it. In practice:

• It tells new clients what they'll need to provide, from your list.
• It doesn't ask for or accept copies of passports, driving licences or bank statements in a chat or on WhatsApp.
• It doesn't ask about the source of funds or wealth, or anything else that belongs in your risk assessment.
• It doesn't tell anyone that a check has been passed or failed.
• It never says anything that could tip someone off about a suspicion. If a caller asks about anything to do with reporting, it hands over.

The assistant's part ends at "please have photo ID and proof of address ready for your onboarding meeting". Your staff do the checks, in your system.

Professional conduct and the no-advice rule

If you or your staff are members of one of the bodies behind Professional Conduct in Relation to Taxation (PCRT), you'll know it sets out fundamental principles that include professional competence and due care, and confidentiality. An AI giving off-the-cuff answers about allowable expenses would sit badly with both. The no-tax-advice instruction isn't just about avoiding mistakes. It keeps advice where your competence, your engagement letter and your professional indemnity insurance apply.

Client confidentiality

Accountants know more about their clients' finances than almost anyone. The assistant must keep that confidence in the same way your receptionist does:

• It never confirms whether someone is a client.
• It never discusses a client with a spouse, a family member, a lender or anyone else.
• It never repeats figures, deadlines or HMRC correspondence. It can't see them anyway.

Data protection and Klugon

Most of what an accountant holds is ordinary personal data, but there's a lot of it and it's sensitive in practice: income, debts, national insurance numbers, bank details. The safest design is for the assistant not to collect any of that. Names, contact details, the type of work and the company name are enough for first contact.

Here's what to put in your assessment of Klugon:

• Klugon is operated by Softaar Technologies UG, a German company, under the GDPR.
• Sub-processors include Google Firebase, OpenAI and Telnyx, which the privacy policy lists as US-based, with Standard Contractual Clauses covering the transfers. We don't claim data is held in the UK or EU.
• Klugon is not certified for SOC 2 or ISO 27001.
• Calls are not recorded. Each call shows in the inbox with its duration and a message log, which may include only the assistant's side.
• Each practice's data is held separately, and knowledge search is filtered to your practice.
• Records can be exported as CSV and deleted one by one. Full erasure is by email request.

Tell the assistant in so many words never to ask for a UTR, national insurance number, bank details or passwords. Clients sometimes offer them unprompted. The instruction should be to say "please don't send that here", and leave it there.

How it compares with tools accountants already use

Measuring whether it's working

Look at these after January, and again after the July payments on account.

New-client enquiries by week. The analytics page shows calls, conversations and leads by day and hour. Compare January's leads with the number of voicemails you used to wade through.

Discovery calls booked and clients signed. Bookings the assistant made are in the bookings list. Mark leads as contacted, converted or lost so you can see how many became clients.

Handovers. The "handled by the assistant" figures show how often it handed over. Read them. A lot of handovers about the same question usually means the answer is missing from your knowledge base. Very few handovers in January is worth checking too, in case it's answering tax questions it shouldn't.

The most asked questions. The insights page lists the most asked questions in the last 30 days and the ones without a good answer. In January those will be about deadlines and fees. Add answers as they come up.

Frequently asked questions

Will the AI receptionist give tax advice?

No. It's instructed to decline every question that depends on a client's own circumstances, including expenses, VAT registration, incorporation, penalties and Making Tax Digital, and to book a call or take details instead. You write the instruction and test it before clients reach it.

Can it carry out our AML and ID checks?

No. It tells new clients what to have ready, from your own list, and nothing more. It doesn't collect ID documents or ask about the source of funds. Customer due diligence is done by your staff in your own systems.

Is a tax advisor chatbot safe to put on our website?

As a receptionist, yes: answering how the practice works, quoting published fees and booking calls. As a source of tax answers, no. Configure it so every tax question is handed to a qualified person, and check the conversations regularly.

Can it tell clients whether their return has been filed?

No. It can't see your practice software or HMRC records. It takes the question and flags it, and someone from the practice replies.

Can it handle the 31 January rush?

It can answer as many of the calls that reach it as your plan's minutes allow, and extra minutes are billed at $15 per started 100. What it can't do is file returns, so set a cut-off for new January clients and make sure the assistant gives it out.

Does it send appointment reminders or confirmation emails?

No. Klugon doesn't send reminders, confirmations or text messages. The booking reference is given in the conversation, and anything else is sent by your team.

Can it transfer a caller to an accountant?

No. There's no live call transfer. The assistant flags the conversation as needing a person, notifies Slack or Zapier, and tells the caller someone will get back to them.

Does it work with Xero or QuickBooks?

Not directly. It can't see client books or practice software. It can tell clients which software you support, and the website chat can be added to any site with one script tag.

Does it record calls?

No. Calls aren't recorded. Each call appears in the inbox with its duration and a message log, which may show only the assistant's side.

Can I keep my office number?

Yes, by forwarding it to a Klugon number. Numbers are available once the 7-day trial ends, and the trial needs a card and is charged at the end unless you cancel.
