This kit is one file with three parts: how to use it, an interview prompt for your AI, and the Guide itself. ## How to use this kit (3 steps, about 15 minutes) 1. Open the AI you already use (ChatGPT, Claude, Gemini, anything that reads markdown) and paste in everything from "INTERVIEW PROMPT" below, including the Guide at the end. 2. Your AI interviews you like a colleague, one question at a time. Just talk: war stories, walk-throughs, the mistakes you catch. No writing required. 3. Your AI writes your answers up as a single markdown file. Hand it back at openaccountants.com/skills/stamp-duty-matrix/handback (also linked from the Guide page: "Hand back your file"). What you added is published under your name and credential. If your AI cannot produce the exact output format, hand back whatever you have: a revised Guide file, a worksheet, or plain notes. We take those too, and a person reviews them by hand. The format below is the one we can apply straight away. --- # INTERVIEW PROMPT (paste from here down into your AI) You are interviewing a practising accountant about how they actually do the work covered by the attached Guide ("Stamp Duty Matrix", slug `stamp-duty-matrix`). Interview them like a colleague doing a handover. Do not lecture. Ask ONE question at a time and wait for the answer. Chase war stories and specifics: what kind of client, which portal step, how big the penalty was. The rates, thresholds, and citations are our job; we refresh those from primary sources. Capture ONLY what is NOT derivable from law: - order of operations, and what a wrong order corrupts - what to ask a client before computing anything - what to assume when a fact is unknown, and how it gets flagged - the most-missed traps, with penalty size and who falls in - how the portal or filing channel actually behaves - what has to reconcile before anyone signs - when to refuse the work and hand it to a human specialist If the accountant corrects a rate, threshold, or deadline in the Guide along the way, record it in the FACT CORRECTIONS table, but do not steer the interview toward numbers. ## Questions to work through Ask these in order, one at a time. Skip any the accountant has already covered; follow up where a story has specifics worth pinning down. Each question is tagged with the method slot(s) it feeds. 1. [sequence] Walk me through the last one of these you did for a real client, start to finish. What did you open first, and why that order? 2. [intake_questions] A new client sits down for this work. What are your first five questions before you touch a number? 3. [evidence] Which documents do you insist on seeing, and which do you take the client's word for? 4. [trap] When you review this work drafted by someone else, what mistake do you catch most often? 5. [conservative_default] When a key fact is unknowable at draft time, what do you assume, and how do you flag it? 6. [judgment_rule] When the law allows two routes, how do you actually pick, and what do you write down about the choice? 7. [cross_check] Before you sign, what has to reconcile with what, and how close is close enough? 8. [filing_mechanics] Walk me through the actual submission: the portal steps, the order things must happen in, what locks, what you can't undo. 9. [scope_gate] Which clients do you refuse or refer to a specialist for this work? What makes you stop? 10. [unsettled_law] Anything here you deliberately won't finalise right now because the rules are moving? 11. [handback_protocol] What exactly do you hand over at the end? What's in your working paper? ## Method slots (for tagging the write-up) - `scope_gate` (Scope gate and refusals): when to stop and send the client to a human - `sequence` (Order of operations): what order to do things in, and what a wrong order corrupts - `intake_questions` (Client intake questions): what to ask a client before computing - `evidence` (Documents and evidence): which documents to insist on, and what is draft-grade vs file-grade - `judgment_rule` (Judgment rules): how a practitioner actually picks when the law allows two routes - `conservative_default` (Conservative defaults): what to assume when a fact is unknowable at draft time - `trap` (Traps and most-missed items): the mistakes everyone makes, what they cost, and who falls in - `filing_mechanics` (Portal and filing mechanics): how submission actually works: channel, order, what locks - `cross_check` (Cross-checks before signing): what has to reconcile with what before delivery, and how close is close enough - `pattern_library` (Pattern library): how messy real-world data (bank lines, payout platforms) maps to tax categories - `edge_case` (Edge-case playbook): the client situations that change the method, not just the numbers - `unsettled_law` (Unsettled-law flags): what not to finalise right now, and why - `handback_protocol` (Hand-back protocol): what the finished working paper contains and who reviews it ## Output format: oa-handback v1 When the interview is done, write the answers up as ONE markdown file in exactly this shape. Fill in the reviewer's real name, credential, and email (ask for them at the end if they have not come up). Every method block gets a `### [method:]` heading where `` is one of the 13 slot ids above. Keep `guide_slug` and `guide_version` exactly as given. Omit any section the interview produced nothing for, but keep the headings that remain exactly as shown. The `fact_key` column may be left blank when unknown. ```markdown --- oa_handback: v1 guide_slug: stamp-duty-matrix guide_version: stamp-duty-matrix@2026-05-23T06:28:18.768Z reviewer_name: reviewer_credential: # free text: CPA, EA, ACCA, Steuerberater... reviewer_email: verdict: --- ## METHOD ### [method:filing_mechanics] ### [method:intake_questions] - - ... ## FACT CORRECTIONS | fact_key | current | correct | source | |---|---|---|---| | | | | | ## FLAGS - [unsettled] - [refer] ## NOTES ``` If for any reason you cannot produce this exact format, output the accountant's corrections and methods as clear plain notes instead. The hand-back page accepts plain notes and revised Guide files too; this format is an optimization, never a gate. --- # THE GUIDE UNDER REVIEW --- name: stamp-duty-matrix description: Use this skill whenever an attorney, transaction lawyer, or in-house counsel asks about stamp duty on documents, securities transfers, or financial transactions.

0.13% old rate not applied post-November 2023) - [ ] Singapore ACD tested for property-rich entity transfers - [ ] India federal + state stamp duty stacked correctly - [ ] Brazil IOF / Argentina sellos / Chile timbres per applicable transaction type - [ ] Output flags every [T2]/[T3] item for reviewer judgement ## Section 13 — Prohibitions - **Prohibitions list** — - **Do not** apply the old 0.13% Hong Kong stamp duty rate to transactions executed after November 2023 — the rate is 0.10% per side. - **Do not** assume UK intra-group relief applies without confirming 75% common beneficial ownership AND the relief application has been correctly notified. - **Do not** advise that AIM-listed shares are exempt without confirming the listing is on a HMRC-recognised growth market. - **Do not** ignore Italian / French / Spanish FTT for non-resident purchasers — the tax is at the security level, not the purchaser's residence. - **Do not** apply property-rich entity rules (Singapore ACD, Australian landholder duty) without confirming the threshold (typically 50% of tangible assets) and qualifying equity interest tests. _(Section 13 — Prohibitions)_ ## Section 14 — Disclaimer This skill and its outputs are provided for informational and computational purposes only and do not constitute tax, legal, or financial advice.
