Verified Tax Vat Global | Tax Year Tools | Ai2fin

AI2Fin Tax MCP — free tax rates, GST/VAT, income, company and capital-gains tax for 50+ countries, over the Model Context Protocol The Tax MCP by AI2Fin (2Fin) is a free, public MCP server that gives any assistant or agent — Claude, ChatGPT, Cursor, VS Code, or a custom build — instant access to accurate, source-cited tax data. No login, no API key, no setup beyond pasting one URL: https://taxmcp.ai2fin.com. Every answer cites the national tax authority it came from (ATO, IRD, HMRC, IRS and more) with a verified date, so you always know a number is current — and where to confirm it. What you can do with it: Look up any country's tax rates — GST/VAT standard and reduced rates, top personal income tax rate, and company tax rate for 50+ countries, from Australia and New Zealand to the UK, US, India, Canada, the EU and beyond (tax_rate_lookup). Add or remove GST/VAT on any amount — instant tax-inclusive ↔ tax-exclusive conversion for invoices, quotes, pricing and expense checks, using the right rate for the right country automatically (compute_gst_vat). Compare tax across countries side by side — GST/VAT, income and company tax in one call, for relocation research, market expansion or pricing strategy (compare_countries). Estimate income tax and take-home pay for Australia and New Zealand, computed over effective-dated brackets that roll over automatically at each financial year (income_tax_estimate). Estimate company tax on a profit for Australia, the US, UK, India and Canada — including small-business rates and thresholds, not just the headline figure (company_tax_estimate). Estimate Australian capital gains tax for resident individuals — capital losses, the 12-month CGT discount, and marginal-rate stacking on top of your income, handled correctly (cgt_estimate). Countries only answer when their data is verified against an official source; anything unverified degrades gracefully to "not available" instead of guessing. The server is stateless and private by design — it computes over published rate data only and stores nothing you send. It runs the same single-source dataset behind the free browser calculators at ai2fin.com/tools, so the MCP, the embeddable widgets and the web calculators never disagree. Listed in the official MCP registry as https://taxmcp.ai2fin.com/ . Works with any MCP client over streamable HTTP. General information, not tax advice — every figure links to the authority so you can confirm it. For your own transactions, categories and real tax position, the separate authenticated 2Fin app MCP at api.ai2fin.com/mcp picks up where this one ends.
