None of them can stand behind an answer. Here, real accountants put their **name, credential and review date** on the Guides your AI reads โ€” publicly, on the record, in this repo.

Prefer self-hosting or manual files? - **pip MCP server:** `pip install openaccountants-mcp` (mirrors this repo's `packages/`) - **Manual:** download your jurisdiction's folder from [`packages/`](https://github.com/openaccountants/openaccountants/blob/HEAD/packages/) and upload the files to your AI. Start with your country's main package; `index.json` is the machine-readable inventory.
--- ## Two states, greppable honesty Every Guide is in exactly one state โ€” 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](https://github.com/openaccountants/openaccountants/blob/HEAD/VERIFIERS.md) | | **Source-cited draft** | Written from primary legislation, every figure cited to its source โ€” not yet professionally reviewed | โš ๏ธ **General reference, not advice.** Guides may be incomplete, outdated, or wrong for your facts.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 โ€” 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 โ€” 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* โ€” your contribution graph reflects your work. The current roster: **[VERIFIERS.md](https://github.com/openaccountants/openaccountants/blob/HEAD/VERIFIERS.md)** (generated nightly from the platform). --- ## How it stays accurate A tax library is only as good as its worst stale number, so machines re-check this one every night: - **The maths check** re-reads every guide and flags sums that do not add up, tax bands with gaps, totals that do not total, and years that disagree. - **The source watch** visits the official pages the figures came from and raises a hand when a page changes. - **The refresh engine** re-derives the stalest guides from official sources on a fixed monthly budget, refusing to publish any figure without a link. - **The nightly exam** tests whether AIs actually said what the guides say that day, or improvised. Improvisation gets caught, counted and fixed at the source. The sync runs both ways: platform edits land here as commits under the author's own name, and merged PRs here flow back into what every AI serves, credited to you. A guide with an accountant's byline never changes without that accountant's one-click approval.
