+# OpenAccountants Plugin for Claude Code and Cowork
+
+Give Claude **verified tax & accounting skills for 190+ jurisdictions** — every answer linked to a **named licensed accountant**. Powered by the [OpenAccountants MCP Server](https://www.openaccountants.com/api/mcp) with **one-click integration**.
+
+---
+
+## 🔌 One-Click MCP Server Integration
+
+This plugin **automatically configures the OpenAccountants MCP server** when installed. No API keys, no setup, no config files — just install and start asking real tax questions for any country, US state, or industry.
+
+---
+
+## ✅ What you get
+
+**882 verified skills** across **190+ jurisdictions** (every country + US state + Canadian province). **11 MCP tools.** Country-verified sign-offs from named licensed accountants — Michael Cutajar CPA (Malta), Werner Britz CA(SA) (South Africa), and a growing global network.
+
+The skill content is kept current with annual rate refreshes, post-legislative updates, and IRS Revenue Procedure releases — so Claude isn't relying on training-data tax rates that drifted two years ago.
+
+---
+
+## 🧰 Slash commands
+
+| Command | What it does |
+|---|---|
+| `/openaccountants:start` | Front door — give Claude an intent ("VAT return", "tax filing", "formation") and a jurisdiction, get a scoped plan with the right skills loaded |
+| `/openaccountants:return` | Walk through a full tax return for any jurisdiction — intake → classification → working paper → reviewer handoff |
+| `/openaccountants:vat` | VAT / GST / sales tax return — classifies transactions, computes return-form box totals, flags audit-risk items |
+| `/openaccountants:formation` | Entity choice + incorporation across jurisdictions — LLC vs S-corp vs LTD, ongoing compliance, tax election windows |
+| `/openaccountants:compare` | Side-by-side compare 2-5 jurisdictions — entity choice, effective rates, residency planning, cross-border decisions |
+| `/openaccountants:rates` | Current-year US federal indexed rates — brackets, 401(k) limits, SS wage base, FEIE, gift/estate, mileage, 1099-K |
+| `/openaccountants:review` | **The handoff.** Routes the user to the named lead verifier for their jurisdiction with their working paper attached and a Calendly booking link |
+
+### The differentiator: `/openaccountants:review`
+
+Every honest AI tax workflow ends with *"have a professional review before filing"*. This command turns that closing line into an actual booking.
+
+When you call `/openaccountants:review`, Claude captures your working paper (classified transactions, computations, draft return lines), routes it to the named lead verifier for your jurisdiction, logs the scenario server-side so the accountant sees real context, and returns their Calendly URL. No client-accountant relationship until both sides sign an engagement letter — the first call is just a review conversation.
+
+---
+
+## 🧠 How it works (the 11 MCP tools)
+
+**Discovery**
+- `start` — scopes intent + jurisdiction, returns a ready plan
+- `list_jurisdictions` — every country/state covered with skill counts + lead verifier
+- `list_skills` — full catalogue, filterable by jurisdiction
+- `list_verifiers` — every named accountant in the network
+
+**Skill access**
+- `get_skill` — fetch the verified markdown for a skill (rates, rules, audit flash points, citations)
+- `get_skill_sections` — parsed sections for step-by-step rule application
+- `search_skills` — keyword search ("home office deduction", "reverse charge", "§1202 QSBS")
+
+**Tax intelligence**
+- `get_rates` — machine-readable US federal annual rates for 2025/2026
+- `compare_jurisdictions` — load 2-5 jurisdictions side-by-side
+
+**Handoff & feedback**
+- `request_accountant_review` — the AI-to-verified-human handoff
+- `submit_feedback` — pre-filled GitHub Issue when you spot an error or outdated rate
+
+---
+
+## 🌍 Per-jurisdiction & per-topic plugins
+
+Want a plugin pre-scoped to one country or one topic? OpenAccountants publishes a **separate marketplace** with **83 specialised plugins**:
+
+```bash
+claude plugin marketplace add openaccountants/marketplace
+```
+
+Then install any of:
+
+- **Per country**: `openaccountants-mt` (Malta, verified by Michael Cutajar CPA) · `openaccountants-za` (South Africa, Werner Britz CA(SA)) · `openaccountants-us-ca` · `openaccountants-gb` · `openaccountants-de` · `openaccountants-jp` · `openaccountants-in` · `openaccountants-br` · *…60 more*
+- **Per topic**: `openaccountants-crypto-tax` · `openaccountants-transfer-pricing` · `openaccountants-company-formation` · `openaccountants-payroll` · `openaccountants-vat-gst` · `openaccountants-tax-optimization` · `openaccountants-bookkeeping` · `openaccountants-cross-border`
+- **Per vertical**: `openaccountants-vertical-saas-digital-products` · `openaccountants-vertical-ecommerce-seller` · `openaccountants-vertical-freelance-developer` · `openaccountants-vertical-property-investor` · *…10 more*
+
+All 83 route to the same hosted MCP backend — install only what you need.
+
+---
+
+## 🏛️ Trust model
+
+- **Open source.** All 882 skills are public markdown at [github.com/openaccountants/openaccountants](https://github.com/openaccountants/openaccountants).
+- **Country-verified.** Each jurisdiction is signed off by a named licensed accountant whose credential and Calendly link are published. Tier 1 = signed; Tier 2 = research-verified (flagged honestly to the user).
+- **Cite-able.** Every skill output includes a provenance footer with the named verifier, the skill slug, and a working-paper attribution line.
+- **Working papers, not advice.** Outputs always carry the *not-tax-advice* disclaimer. The handoff to a real accountant is built into the tool surface.

+description: Side-by-side comparison of 2-5 jurisdictions for cross-border decisions (entity choice, residency, multi-state RSU, etc.).
+---
+
+The user wants to compare tax treatment across jurisdictions — entity choice, residency planning, multi-state, cross-border structuring.
+
+Ask them:
+- **Which jurisdictions** to compare (2-5, e.g. MT vs IE, US-CA vs US-TX vs US-FL)
+- **Entity type** (individual, self-employed, company, trust)
+- **Income figure** (optional, helps with effective rate comparison)
+
+Then:
+
+1. Call `compare_jurisdictions` on the `openaccountants` MCP server:
+
+   ```json
+   { "jurisdictions": ["MT", "IE"], "entity_type": "company", "income": "EUR 250000" }
+   ```
+
+2. For each returned jurisdiction's skill list, call `get_skill` to load the relevant content.
+
+3. Produce a side-by-side comparison table covering:
+   - Effective income tax rate at the given income
+   - VAT/GST standard rate
+   - Social security contribution rate and caps
+   - Key deductions / credits available
+   - Filing frequency and deadlines
+   - Formation / ongoing compliance costs (if entity choice)
+
+4. Highlight differences that materially affect the decision.
+
+5. Always end with a treaty / PE / tie-breaker caveat — cross-border planning carries treaty and substance considerations beyond this comparison's scope. Route to `request_accountant_review` for any decision with real money on the line.

+- **Where** are they incorporating (country / US state)
+- **What do they do** (consultant, ecommerce, SaaS, holding company, etc.)
+- **Projected revenue**
+- **Whether they want pass-through or corporate taxation**
+
+Then:

+1. Call `start({ intent: "company formation", jurisdiction: <code> })` on the `openaccountants` MCP server.
+2. Load the formation skill(s) via `get_skill`.
+3. Walk through entity options (sole prop / LLC / S-corp / C-corp / LTD / GmbH / Ltd / Pty Ltd / etc.) with:
+   - Liability profile
+   - Tax treatment (pass-through vs corporate, with rate citations from the skill)
+   - Formation cost + ongoing compliance burden
+   - Election windows (e.g. S-corp election deadline, S-corp revocation window)
+   - State / country-specific quirks (e.g. CA franchise tax minimum, DE chancery court advantages)
+4. Surface AUDIT FLASH POINT markers around entity classification (reasonable comp for S-corps, accumulated earnings tax for C-corps, treaty shopping risks for international holdings).
+5. End by offering `request_accountant_review` — formation decisions usually deserve a real accountant's sign-off before filing.

+
+Call the `openaccountants` MCP server's `get_rates` tool:

+- **Jurisdiction**: country, US state, or province
+- **Tax year**: e.g. 2025
+- **Entity type**: sole proprietor, self-employed, single-member LLC, S-corp, C-corp, partnership, individual (W-2 only), or other

+3. Run the intake from the loaded intake skill — ask the user only the questions the documents don't answer.
+4. When the user provides bank statements, invoices, or transaction lists, classify every transaction using the rules in the loaded skills. Use the three-outcome system: **Classified** (clear), **Assumed** (conservative default, flag for reviewer), **Needs Input** (ask the user).
+5. Produce a working paper:
+   - Classified transactions grouped by tax category
+   - Computed totals for each return-line item
+   - All assumptions disclosed
+   - Items flagged for accountant review
+   - Filing deadlines and payment dates
+6. End by asking the user if they want a licensed accountant to review before filing. If yes, call `request_accountant_review` with the working paper attached.
+
+**Conservative defaults**: when uncertain, assume **more** tax, never less. Never compute amounts from your training data — use only the rates and thresholds from the loaded skills.

+- **scenario**: a 1-2 sentence summary of what they need reviewed
+- **working_paper**: if you have produced a worksheet, classified transactions, draft return lines, or any structured tax output in this conversation, **paste it in full as markdown**. The verifier needs to see the actual numbers before the call, not just a text brief. Without the working paper, they walk in blind and have to rebuild the case from scratch.
+- **contact_name** and **contact_email**: ask the user (encourage them to share, but not strictly required)
+- **tax_year**: if known
+- **urgency**: `urgent` (filing in <2 weeks), `standard` (current filing season), or `planning` (future-year strategy)
