# OpenAccountants **Open-source Tax Guides your AI can cite — reviewed by named, licensed accountants.** Every AI can do tax math. None of them can stand behind an answer. Here, real accountants put their **name, credential and review date** on the Guides your AI reads — publicly, on the record, in this repo.

Start with your country's main package; `index.json` is the machine-readable inventory. </details> --- ## Two states, greppable honesty Every Guide is in exactly one state — and the repo greps honestly: | State | Meaning | |---|---| | **Accountant-reviewed** | A named, licensed accountant reviewed the complete Guide. Their name is in the frontmatter (`reviewed_by:`) and on [the public roster](VERIFIERS.md) | | **Source-cited draft** | Written from primary legislation, every figure cited to its source — not yet professionally reviewed | ⚠️ **General reference, not advice.** Guides may be incomplete, outdated, or wrong for your facts. Have a qualified professional review outputs before filing, payment, or action. --- ## Are you an accountant? Your name on the tax knowledge AI actually uses — with attribution built in: 1. **Build a Guide** for the work you know cold: [openaccountants.com/skills/new](https://www.openaccountants.com/skills/new). It publishes credited to you, and lands in this repo under your name. 2. **Review a Guide** in your jurisdiction — your name, credential and review date go on it, here and on every AI answer that cites it. 3. **Set your GitHub username** in [your profile](https://www.openaccountants.com/profile) and your platform edits are committed to this repo as *you* — your contribution graph reflects your work.
