OpenAccountants
The open-source tax layer for AI agents.
1,000+ skills across 190+ jurisdictions — research-verified, with an accountant-verified tier signed off by named CPAs/CAs/EAs. Works with Claude, ChatGPT, Cursor, Windsurf, and any MCP-compatible agent.
⚠️ General reference only — not advice. OpenAccountants provides general tax and accounting reference material for AI-assisted workflows. It is not a law firm, accounting firm, tax preparer, or return-filing service, and its outputs are not tax, legal, accounting, or financial advice. Skills may be incomplete, outdated, or wrong, and are not reviewed for any specific person's facts, elections, deadlines, residency, or local procedures. Always have a qualified professional review outputs before filing, payment, or action. Research-verified skills have not been reviewed by a credentialed accountant.
