Written by Miriad with AI assistance and checked against the sources at the end. A writing template for small accounting and bookkeeping firms, not tax advice; check every rule against the official source before you send.
TL;DR: A tax-change newsletter gets read when it covers one change, says who it affects, and ends with one clear "what to do" line and a date. Five parts: subject, who it affects, what changed, what to do, and when to call. Draft it from the official source, never from client files, and send it through your email tool to a list the rules allow.
A client newsletter can fail before anyone reads a word of it, in the subject line. "Autumn Newsletter" tells the client nothing, so it waits in the inbox until it is deleted. The same email with the subject "Landlords: quarterly reporting starts this tax year" gives every landlord on the list a reason to open it, because it is about them.
This article gives a five-part template for turning one regulation change into a client email, a filled-in example, and the rules for drafting and sending it. It is part of our guide to accounting firm marketing strategies, which checks every channel against client confidentiality.
What makes a tax-change newsletter worth reading?
A tax-change newsletter is worth reading when the client can tell from the subject line that it is about them, and can act on it in one minute. That means one change per email, plain words, a named date, and one action. A round-up of eight changes reads like homework and tends to be saved for later.
Four rules for every issue:
- One change. If there are three changes, send three short emails over three weeks, or lead with the one that affects the most clients.
- Segment the list. Landlords get the landlord email; payroll clients get the payroll email. Your practice management software usually holds the client type.
- One action and one date. "Send us your rental income records by 15 January" is an action. "Be aware of the changes" is not.
- Short. Under 200 words in the body. A link to the full explanation on your website for anyone who wants more.
The five-part template
The template has five parts, in this order: a subject that names the affected group, one sentence on who is affected, two or three sentences on what changed, one "what to do" line with a date, and one line on when to call. Fill the parts from the official source, then cut anything that does not help the client act.
Subject: (Client group): (the change, in five to eight words)
Who this affects: You are affected if (one condition the client can check themselves).
What changed: (Two or three sentences in plain words. The rule, the start date, and what it replaces.) Source: (link to the official page).
What to do: (One action) by (date).
When to call us: If (the situation where it gets complicated), reply to this email or call (phone).
The "who this affects" line does the most work. A client who reads "you are affected if your self-employment and rental income together are over a threshold" can check it in their head. A client who reads "this may affect some taxpayers" cannot.
A filled-in example: Making Tax Digital for landlords
The example below fills the template for a real UK change, Making Tax Digital for Income Tax, for a practice's landlord clients. Every rule in it comes from HMRC's guidance, linked in the body. The client names, the threshold check and the deadline for records are the parts each firm adapts to its own client base.
The rule, from HMRC: Making Tax Digital for Income Tax is mandatory from 6 April 2026 for sole traders and landlords with qualifying self-employment and property income over £50,000, who send quarterly updates through compatible software. An agent can sign a client up, and for 2026–27 HMRC will not apply penalty points for late quarterly updates, though late returns and payments still attract penalties (GOV.UK, 2026).
Example (illustrative, not a real case): A three-person UK practice with 64 landlord clients sends this to the 23 whose income it believes is over the threshold.
Subject: Landlords: quarterly reporting to HMRC has started
Who this affects: You are affected if your rental and self-employment income together were over £50,000.
What changed: Since 6 April 2026, HMRC's Making Tax Digital for Income Tax requires you to send quarterly updates through compatible software instead of only one annual return. For this first year, HMRC will not give penalty points for late quarterly updates, but late returns and payments still carry penalties. Source: GOV.UK.
What to do: Reply "sign me up" by 30 November and we will register you as your agent and set up the software.
When to call us: If you are close to the threshold or have more than one property business, call us and we will check it together.
Count the body: about 110 words. The client knows in the first line whether to keep reading.
How do you draft the newsletter with AI without client data?
Paste the official source and your own notes into the AI tool, ask for the five parts, and check every date and threshold before sending. No client names, figures or files go in. ICAEW is explicit that client data in AI inputs is very likely a confidentiality breach, and that AI output should be reviewed like a trainee's work.
ICAEW's February 2024 notice says that if AI inputs include client data it is "very likely that this will breach client confidentiality", and that output should be checked as you would check a trainee's work (ICAEW, 2024). The newsletter workflow avoids the problem by design:
- Input: the official page text and your notes on what clients usually get wrong.
- Prompt: "Fill this five-part template for (client group). Under 150 words. Plain English. One action and one date. No promises, no superlatives."
- Check: a qualified person compares every date, threshold and form number against the source.
- Send: the email tool merges in first names from the client list. The list never enters the AI tool.
Example (illustrative, not a real case): A two-person US tax practice, an enrolled agent and an assistant, plans a February email to 210 individual clients about the April deadline. The assistant pastes in the IRS "When to file" page: the deadline for tax year 2025 was April 15, 2026, Form 4868 gives an automatic six-month extension, and "an extension of time to file is not an extension of time to pay" (IRS, 2026). The AI draft says "file by April 15 or request an extension". The enrolled agent adds the missing half: if they owe, they still pay by April 15. That correction is the reason for the check.
Which rules apply when you send it?
In the US, a tax client newsletter is one of the uses the IRC 7216 rules explicitly allow, and the recipient list and each issue should be kept for at least 36 months under Circular 230. The same list may not be used to sell other services. Outside the US, your professional code and data protection law set the limits.
The detail, rule by rule:
- What the list may hold and do: under 26 CFR 301.7216-2(n), a tax preparer may keep names, mailing and email addresses, phone numbers, entity classification and return form number, and use the list for educational tax information or to solicit more tax return preparation (Cornell LII, 26 CFR 301.7216-2).
- What it may not do: the same rule says the list "may not be used to solicit any service or product" other than tax return preparation; a monthly tax newsletter to clients is an approved example (Cornell LII, 26 CFR 301.7216-2).
- Records: Circular 230 § 10.30 requires copies of direct-mail and e-commerce communications and their recipient lists to be kept for at least 36 months (Cornell LII, 31 CFR 10.30).
So a newsletter about a payroll rule, sent to the tax return list, with a line advertising the firm's payroll service, needs a second look. Keep the newsletter educational, and offer other services through channels the rules allow. Save each issue and its list in a dated folder.
Plan the issues around your filing calendar with the accounting firm marketing plan template, and reuse each issue as two or three short posts, as described in accounting firm social media.
If you want each issue to sound like your firm, with the template and the advertising rules built into the prompts, the Conversion Copywriting Pack is built for that. Get notified when it launches.
FAQ
How long should a client tax newsletter be?
Under 200 words in the body, covering one change. Clients act on a short email with a clear subject, one action and one date. If there is more to explain, link to a page on your website. If several changes are coming, send separate short emails to the client groups each one affects, rather than one long round-up to everyone.
Can I use AI to write a client tax newsletter?
Yes, if the input is the official source and your own notes, not client data. ICAEW warns that putting client data into AI inputs is very likely a breach of confidentiality, and says output should be reviewed like a trainee's work. Have a qualified person check every date, threshold and form number against the official page before sending.
Can I send a tax newsletter to my tax return clients in the US?
Yes. The IRC 7216 regulations allow a tax preparer to use a client list for educational tax information, and a monthly tax newsletter is an approved example. The same list may not be used to solicit other services or products. Keep copies of each issue and the recipient list for at least 36 months, as Circular 230 requires.
What subject line works for a tax-change newsletter?
A subject that names the affected group and the change, in plain words: for example, Landlords: quarterly reporting to HMRC has started. The client can tell from the first words whether the email is about them. Generic subjects such as Autumn Newsletter give no reason to open the email, so they tend to be left unread.
