Most accountants who try AI tools hit the same problem: the output is too generic to use. A one-line prompt produces a one-size-fits-all email that sounds nothing like your practice, references the wrong jurisdiction, and still needs rewriting from scratch. The tool saves no time at all.

The fix is a better prompt: one that gives the AI a role, a task, the right context, a specific tone, and clear guardrails about what not to do. This article is the practical companion to our complete guide to AI prompts for accountants. Where the full guide covers how prompts work and how to build a library for your team, this page is purely operational: twenty prompts you can copy, paste into ChatGPT, Copilot, or Claude, and use on real work today.

Every prompt below is written for a UK accountancy practice. The examples reference HMRC, Self Assessment, Companies House, and the kinds of clients a 5 to 50 person practice actually works with, not generic placeholders. Each one follows a five-element structure that consistently produces usable first drafts. If you want context on how UK practices are actually adopting AI tools before you dive into the prompts, read our overview of how UK accountancy practices are using AI in 2026. If you are not yet sure whether your practice is ready to adopt AI tools, take our free AI readiness scorecard before you start.

How to use these prompts

Copy the prompt text into ChatGPT, Microsoft Copilot, Claude, or whichever AI tool your practice uses. Replace the placeholder details (client names, dates, figures) with your own. Review the output before using it. Every AI-drafted document should be checked by a qualified person before it leaves the practice.

A note on data protection Several prompts below include placeholder client names and financial details. Before entering real client data into any AI tool, make sure you understand the provider's data processing terms and have considered the UK GDPR implications. Many practices start by using prompts without any identifiable client information, entering only the type of task and the general scenario. Runbook is not responsible for AI output based on these prompts. We recommend as part of our products that you take advice from your Data Protection Adviser or Legal Team before using AI tools with real client information.

Client emails and correspondence

Client communication is the single highest-return area for AI prompts in most practices.

Prompt 1
Missing document request
You are a UK practice accountant writing to a small business client. Draft an email to [Client Name] at [Company Name]. We need the following to complete their corporation tax return for the year ended 31 March 2026: Barclays business account bank statements (April 2025 to March 2026), the vehicle mileage log for the company van, and purchase invoices for any equipment bought over £1,000. We need these by 30 June 2026 to stay on schedule. The filing deadline is 31 March 2027. Tone: friendly but clear. They are reliable but often needs a specific deadline to act. Keep under 140 words. Do not invent any figures.
Adapt the document list and dates for each client. The tone instruction is the key variable.
Prompt 2
Self Assessment deadline reminder
You are a UK practice accountant writing to individual tax clients. Draft a reminder email for personal tax clients who have not yet sent their records for the 2025/26 tax year. The online Self Assessment filing deadline is 31 January 2027. We need records by 30 September 2026. Mention the following: P60 or income confirmation from employer, bank and building society interest certificates, rental income details if applicable, pension contribution statements, and Gift Aid donation records. Tone: professional and helpful. This is a first reminder, not a chase. Keep under 170 words. Sign off as "The team at [Practice Name]." Do not quote any specific tax thresholds or rates.
Use this as a batch template. Send personalised versions by adjusting the document list per client type.
Prompt 3
Fee quote cover email
You are a UK practice accountant writing to a prospective client. Draft an email to [Client Name], who runs a small consultancy (sole trader, turnover approximately £85,000). She has enquired about annual accounts preparation, Self Assessment filing, and quarterly VAT returns. Our quoted fees: annual accounts and Self Assessment, £850 plus VAT. Quarterly VAT returns, £150 plus VAT per quarter. Total annual cost: £1,450 plus VAT. Confirm that these fees include routine correspondence with HMRC and one annual review meeting. Mention that we will send a formal engagement letter if they would like to proceed. Tone: warm, confident, not salesy. They are comparing two practices. Keep under 160 words. Do not give tax advice.
Adjust the services and fees to match your quote. The "she is comparing" context shapes the tone usefully.
Prompt 4
New client welcome email
You are a UK practice accountant welcoming a new client. Draft a welcome email to [Client Name(s)], directors of a newly incorporated limited company called [Company Name]. They have signed our engagement letter for annual accounts, corporation tax, payroll for two employees, and monthly bookkeeping review. Year-end is 31 December. Include: a thank you, a brief summary of what we will handle, what they need to send us in the first two weeks (bank account details, Companies House authentication code, HMRC UTR when received, details of any transactions since incorporation), and how to reach us with questions. Tone: warm, clear, reassuring. They are first-time directors. Keep under 200 words. Do not give tax or legal advice.
First-time directors need more reassurance than experienced clients. The tone instruction handles this.
Prompt 5
Post-meeting follow-up
You are a UK practice accountant following up after a client meeting. Draft a follow-up email to [Client Name], owner of a [industry] business (limited company, 8 staff). We met yesterday to discuss her year-end results and planning for the next financial year. Key points from the meeting: - Turnover grew 14% but margins tightened due to contractor cost increases - We agreed to review her contractor payment structure to check IR35 exposure - She will send us the three contractor agreements by end of next week - We will prepare a dividend vs salary analysis for her personal tax position - Next meeting scheduled for 15 May 2026 Tone: professional, efficient. The client is busy and prefers concise communication. Keep under 160 words. Do not provide tax advice in the email. Present the above as a summary, not recommendations.
Meeting follow-ups are high-value for client relationships but often get skipped because of time pressure. This takes thirty seconds.

HMRC correspondence and tax work

Prompt 6
Explaining an HMRC letter to a client
You are a UK practice accountant explaining HMRC correspondence to a client in plain English. A client has forwarded an HMRC letter stating that their Self Assessment tax return for 2024/25 is under enquiry. The letter references Section 9A of the Taxes Management Act 1970 and requests records relating to property income. Draft a short email to the client explaining: what the letter means in plain language, that this is a routine HMRC check (not an accusation of wrongdoing), what records they will need to gather, and that we will handle all correspondence with HMRC on their behalf. Tone: calm, reassuring. The client is anxious. Keep under 170 words. Do not speculate on the outcome. Do not provide legal advice.
HMRC letters cause disproportionate anxiety. The "calm, reassuring" instruction and the "do not speculate" guardrail are both essential.
Prompt 7
Tax return cover letter
You are a UK practice accountant drafting a cover letter to accompany a personal tax return. Client: [Client Name]. Tax year: 2025/26. Filed online via HMRC. Key figures: total income £74,200, tax liability £14,860, payments on account already made £11,400, balancing payment due £3,460. The balancing payment deadline is 31 January 2027. Payments on account for 2026/27 are £7,430 each, due 31 January 2027 and 31 July 2027. Draft a brief cover letter summarising the return, the key figures, and the payment dates. Mention that the client should check the figures and contact us with any questions. Tone: clear, professional. The client is experienced and prefers brevity. Keep under 150 words. Use only the figures provided. Do not invent or round any numbers.
Replace the client name, figures, and tax year. The structure works for any personal tax return cover letter.
Prompt 8
VAT deadline reminder for clients
You are a UK practice accountant writing to clients who file quarterly VAT returns. Draft a reminder email for clients whose VAT quarter ends 30 June 2026. The filing and payment deadline under Making Tax Digital is 7 August 2026. We need their sales and purchase records, bank statements, and any unusual transactions flagged by 18 July 2026 to allow preparation time. Tone: professional, matter-of-fact. Most recipients are familiar with the process. Keep under 130 words. Do not reference specific VAT rates or thresholds.
Short and functional. VAT-registered clients usually just need the dates and the document list.
Prompt 9
Corporation tax payment reminder
You are a UK practice accountant reminding a client about an upcoming corporation tax payment. Draft an email to [Client Name], director of [Company Name]. Their corporation tax liability for the year ended 31 March 2026 is £12,340. Payment is due to HMRC by 1 January 2027 (nine months and one day after the year-end). Include: the amount, the deadline, how to pay (HMRC online, bank transfer using their corporation tax payment reference), and a note to contact us if they need to discuss payment timing. Tone: straightforward, helpful. Keep under 130 words. Use only the figures provided.
Replace the company name, figures, and year-end date. The structure works for any corporation tax payment reminder.
Prompt 10
Summarising HMRC guidance for internal use
You are a UK tax accountant preparing an internal briefing note. Summarise the key points of HMRC's guidance on the cash basis for self-employed individuals (as of the 2025/26 tax year). Cover: who is eligible, the turnover threshold, how it differs from accruals accounting, the main advantages and disadvantages, and any recent changes. This is for internal practice use, not for clients. Write in concise bullet points. Keep under 250 words. Do not invent any thresholds or figures. If you are not certain of the current threshold, state that it should be verified against the latest HMRC guidance.
The "if you are not certain" guardrail is important. AI tools sometimes state outdated thresholds with complete confidence.

Reports and management commentary

Prompt 11
Management accounts commentary
You are a UK accountant preparing management accounts commentary for a small business client. The client is [Company Name], a limited company operating [describe the business]. Quarter ended 31 March 2026. Revenue: £112,600, up 6% year-on-year. Gross margin: 54%, down from 58% in the prior year quarter due to increased flour and energy costs. Staff costs: £38,400, up 11% following the April 2025 National Living Wage increase. Net profit before tax: £8,900, down from £13,200 in the same quarter last year. Draft a 180-word commentary summarising performance. Highlight the margin compression and staff cost increase as the two key themes. Use language the business owner (not a finance professional) will understand. Do not offer advisory recommendations. Do not invent additional figures.
Replace the company details, figures, and reporting period. The structure works for any quarterly management accounts commentary.
Prompt 12
Year-end summary letter to client
You are a UK practice accountant writing a year-end summary to a sole trader client. Client: [Client Name], [describe their trade or profession]. Year ended 5 April 2026. Turnover: £62,400 (up from £54,800 last year). Allowable expenses: £14,200. Net profit: £48,200. Tax liability estimate: approximately £9,600 (to be confirmed on final return). Draft a summary letter explaining his results in plain English. Mention that turnover has grown, that his expenses ratio is healthy, and that we will confirm the final tax figures when the return is prepared. Include a note that payments on account may apply. Tone: encouraging, clear. The client worries about tax bills. Keep under 200 words. Use only the figures provided. Mark the tax liability as an estimate.
The "worries about tax bills" context produces a noticeably more reassuring tone. Small details in the prompt make a real difference.
Prompt 13
Board meeting minutes summary
You are a UK practice accountant summarising board meeting minutes for a client's records. The following points were discussed at the board meeting of [Company Name] on 12 March 2026. Attendees: [Director Name] (director), [Director Name] (director). Discussion points: - Approved the annual accounts for year ended 30 September 2025 - Agreed to declare a dividend of £15,000 per shareholder for the current year - Reviewed cash flow forecast and agreed to maintain the existing credit facility - Discussed recruiting a part-time office manager, target start date July 2026 - Next board meeting set for 18 June 2026 Draft formal board meeting minutes in standard UK format. Keep factual. Record decisions, not discussion detail. Keep under 200 words.
Board minutes follow a rigid format. AI handles the structure; you verify the facts.

Meeting notes and internal documents

Prompt 14
Structuring raw meeting notes
You are a UK practice accountant organising meeting notes. I had a meeting with a new prospect, [Client Name], who is setting up a limited company to run a personal training business. Here are my rough notes: "wants to incorporate, not sure sole trader vs ltd, turnover maybe 40-50k, works from home and travels to clients, needs to register for PAYE as wants to pay herself salary, also interested in pension contributions through the company, asked about flat rate VAT but not sure if eligible, wants to start trading 1 July 2026" Rewrite these as structured meeting notes with clear headings: Client Details, Services Discussed, Key Questions to Follow Up, and Agreed Next Steps. Use bullet points. Tone: professional, internal use only. Do not provide advice. Present only what was discussed.
This is one of the fastest wins in practice. Messy notes become structured records in seconds.
Prompt 15
Internal process note
You are writing an internal process document for a UK accountancy practice. Draft a step-by-step process note for the task: "Onboarding a new limited company client." The audience is junior staff and trainees. Steps should cover: initial engagement letter, Companies House checks, HMRC agent authorisation (64-8 form or online), setting up the client in our practice management system, requesting key documents (certificate of incorporation, Memorandum and Articles, bank details, UTR letter), and scheduling the first review meeting. Write in numbered steps. Each step should be one to two sentences. Include a note at the end reminding the reader to update the client tracker spreadsheet. Tone: clear, instructional, no jargon. Keep under 250 words.
Internal documentation gets deprioritised in busy practices. AI brings the effort low enough to actually get it done.
Prompt 16
Staff announcement about a new process
You are a practice manager at a UK accountancy firm writing an internal announcement. Draft a short email to all staff announcing that the practice is introducing a new document collection process. From 1 May 2026, all client records for annual accounts and tax returns should be uploaded to the shared client folder in our document management system within 48 hours of receipt. No records should be stored in personal email folders. The reason: to improve audit trail, reduce duplication, and ensure nothing is missed during busy periods. Tone: positive, clear, not heavy-handed. This is a process improvement, not a reprimand. Keep under 130 words.
Staff communications matter for practice culture. The "not heavy-handed" guardrail prevents the email sounding like a telling-off.

Engagement letters and standard documents

Prompt 17
Engagement letter cover email
You are a UK practice accountant sending an engagement letter to a new client. Draft a cover email to accompany the engagement letter for [Client Name], a sole trader [trade or profession]. The engagement covers annual accounts preparation and Self Assessment filing. Annual fee: £650 plus VAT. Ask him to read the engagement letter, sign it electronically or print and sign, and return it to us before we begin work. Mention that the letter sets out our responsibilities and his, and that he is welcome to ask questions about anything in it. Tone: professional, friendly. The client is straightforward and does not like unnecessary formality. Keep under 120 words.
The cover email matters more than most practices realise. It sets expectations and starts the relationship well.
Prompt 18
Disengagement letter
You are a UK practice accountant drafting a disengagement letter. We are ceasing to act for a client, [Company Name], at the end of the current engagement (year ended 31 March 2026). The reason is that the client has repeatedly failed to provide records on time despite multiple requests, making it impossible to meet filing deadlines. Draft a professional disengagement letter. Cover: confirmation that we are ceasing to act after completing the current year's work, the date from which we will no longer be their accountants, a reminder of outstanding filing obligations they will need to manage or appoint a new accountant for, and confirmation that we will transfer records to their new accountant on written request. Tone: professional, neutral, factual. No blame, no emotion. Keep under 200 words. Do not provide legal advice.
Disengagement letters require a neutral tone that is difficult to get right when the relationship has been frustrating. AI handles this well.

Client onboarding and relationship management

Prompt 19
Six-month client check-in email
You are a UK practice accountant writing a proactive check-in email to a client. Draft an email to [Client Name] at [Company Name] (limited company, 4 staff). We last spoke at their year-end review in November 2025. This is a six-month check-in to see how the business is going and whether anything has changed that we should know about. Mention: any changes to the business (new staff, new premises, significant new contracts), whether her bookkeeping is up to date, and a reminder that we are available if she needs anything before the next formal review. Tone: warm, conversational. The client is long-standing. Keep under 130 words. Do not give advice.
These emails strengthen client relationships and often surface work that would otherwise arrive as a last-minute panic. They take thirty seconds with a prompt.
Prompt 20
Client onboarding checklist email
You are a UK practice accountant sending a new client their onboarding checklist. Draft an email to [Client Name], who has just signed our engagement letter. The client is a sole trader running a [describe type of business] (one employee besides herself, turnover approximately £95,000). Provide a numbered checklist of what we need from her in the next 14 days: 1. Copy of photo ID (passport or driving licence) for anti-money laundering checks 2. Proof of address (utility bill or bank statement, dated within the last 3 months) 3. Last two years' tax returns (if available from her previous accountant) 4. Current year bank statements to date 5. Details of any outstanding HMRC correspondence 6. Employee details for payroll setup (name, NI number, start date, salary) Tone: organised, reassuring. The client is switching from another accountant and slightly anxious about the transition. Keep under 180 words.
Adapt the checklist items to match your own onboarding requirements. The reassuring tone is especially important for clients transferring from another practice.

Making the most of these prompts

Twenty prompts is a solid starting point, but the real value comes from what you do next. Here are three suggestions.

Adapt, do not just copy. Every prompt above is a template. The names, figures, and dates are placeholders. The structure, tone instructions, and guardrails are the reusable parts. Spend thirty seconds customising each prompt to your specific situation and the output will be noticeably better than a generic copy-paste.

Save the ones you use most. If you find yourself reaching for the same three or four prompts every week, save them in a shared document your team can access. A prompt library does not need to be complicated. A shared Google Doc or a pinned note in your team chat is enough to start.

Always review before sending. AI produces fluent, confident text. It also occasionally invents deadlines, fabricates HMRC thresholds, and hallucinates details. Every output needs a human check. Treat AI drafts the way you would treat work from a competent but new junior: useful, but not to be sent without review.

These 20 prompts are shorter examples. Our 50 prompt pack is a more detailed, fully structured pack Our AI Prompt Pack for UK Accountancy Practices includes 50 prompts covering client emails, HMRC correspondence, meeting notes, internal documents, report commentary, and more. Each prompt is written for UK practices, tested on real tasks, and ready to copy into your workflow. £19, instant download.

The bottom line

AI will not replace the judgement, expertise, and client relationships that make your practice valuable. What it can do is handle the repetitive drafting work that eats hours every week: the emails, the cover letters, the meeting notes, the reminders.

The twenty prompts above cover the tasks that come up most often in a typical UK practice. A few things to take away. Detail matters: longer prompts with role, context, tone, and guardrails consistently outperform short ones. UK specificity matters: prompts written for HMRC, Self Assessment, and Companies House produce results you can actually use without rewriting. And review always matters: every AI draft should be checked by a qualified person before it leaves the practice.

Start with the two or three prompts closest to your daily work. Use them until the habit is automatic, then expand. The time saving compounds quickly once you stop treating each task as a one-off.

If you want to go further, the AI Prompt Pack for UK Accountancy Practices includes 50 tested prompts covering every area of practice.
