What you'll accomplish
By the end of this guide, you'll have Claude Pro set up as your dedicated client letter drafting assistant — turning your tax return notes into professional, personalized client letters in under 5 minutes. Tax explanation letters, planning summaries, engagement communications, and IRS response drafts all become quick review-and-send tasks instead of long writing sessions.
What you'll need
Go to claude.ai, create an account with your work email, and select the Pro plan. Claude Pro's longer context window is important for complex tax situations where you're pasting substantial notes.
At the start of every Claude session for client letters, paste this context (customize the bracketed sections):
You are a professional tax communication assistant for [FIRM NAME], a [regional CPA firm / Big 4 affiliate / corporate tax department] serving [individual clients / business clients / both].
Writing standards:
- All letters are professional but approachable — not overly legalistic
- We avoid tax jargon unless absolutely necessary; when using technical terms, define them briefly
- Letters are signed by [Tax Manager / CPA / Partner name]
- Our clients range from high-net-worth individuals to mid-market businesses
- Tone should be confident and advisory — we're explaining, not apologizing
When I give you facts about a client situation, draft a letter following these principles. Do not invent facts. If something is missing, use [PLACEHOLDER] so I can fill it in.
This context persists for the entire conversation, so every letter in the session matches your firm's standards.
After setting context, paste your client notes and request:
"Draft a client explanation letter from these notes: [paste your notes]"
Or be specific about type:
What you should see: A complete, well-structured letter in your firm's tone.
From the same set of facts, get multiple versions:
Save your most successful prompts as text snippets in Outlook, Notepad, or a shared drive file. When you need the same type of letter next week, copy-paste the prompt, update the client-specific facts, and you're done in 2 minutes.
"Why do I owe?" letter:
Draft a client letter explaining why they owe [amount] this year. Plain language, empathetic. Key reasons: [paste 2-4 bullet points with amounts]. Recommend they take these steps to avoid a similar situation next year: [list steps].
Year-end planning summary:
Draft a year-end planning letter for a [client type] client. Their situation: [paste 3-5 bullets]. Highlight these action items before December 31: [list actions]. Each action should include why it matters and an estimated tax impact. Professional advisory tone.
IRS notice response explanation:
Draft a letter to a client explaining that we received IRS Notice [type] on their behalf and what it means. We are [agreeing / disagreeing / responding with documentation]. Our position: [explain in plain terms]. What the client needs to do (if anything): [or "nothing at this time"]. Reassuring tone — this is a routine matter we handle regularly.
After a client meeting:
Draft a follow-up letter summarizing our planning meeting. Points discussed: [paste your meeting notes]. Decisions made: [list]. Action items we agreed on (with who is responsible): [list]. Professional but conversational — this confirms our shared understanding.
