## What it does

OpenAccountants is a public tax knowledge layer where named, licensed accountants review jurisdiction-specific guides that AI agents load when answering tax questions. The repo holds 1,000+ guides across 190+ jurisdictions — income tax, VAT/GST, payroll, SSC, entity formation, bookkeeping, and crypto tax. 13 countries have the full accounting suite (UK, Germany, Malta, Australia, Canada, India, Spain, France, Japan, Netherlands, Portugal, Belgium, US). Every guide is in one of two states: source-cited draft (written from primary legislation, not yet professionally reviewed) or accountant-reviewed (a named, licensed Partner checked the complete guide; their badge appears on every answer). An accountant-reviewed US guide (Christopher Aryee, CPA) was updated with 33 corrections for the OBBBA in July 2026.

## Key commands

Hosted MCP (1 step, always current):

    https://www.openaccountants.com/api/mcp

Local install (no clone needed):

    pip install openaccountants-mcp

Then add to your MCP config:

    { "mcpServers": { "openaccountants": { "command": "openaccountants-mcp" } } }

Manual (no MCP): download a jurisdiction package from packages/ and attach the .md files to your Claude Project or ChatGPT session.

## When to use

Use this when you need jurisdiction-aware tax guidance for a client or your own situation — income tax, VAT, payroll, or entity setup — and you want the AI to load current, source-cited rules rather than rely on training data. All outputs require review by a qualified professional before filing, payment, or action. The MCP connector is the recommended path for accountant-reviewed guides with Partner attribution.
