OpenAccountants ships open-source AI accounting skills that any coding agent can run. Every tax rule cited to statute. Every computation verified by real CPAs. Every position conservative by default.
OpenAccountants isn't an app you log into. It's a library your AI agent loads when it needs to do accounting. Composable. Verifiable. Open.
Every tax position references the actual law. IRC sections, Revenue Procedures, local tax codes. Your CPA can verify in minutes, not hours.
When uncertain, the system defaults to higher tax liability. Never optimistic. Never aggressive. The kind of output a CPA would sign.
Clone the repo. Read every line. Fork it. Contribute back. No black boxes. No vendor lock-in. Tax rules belong in the open.
Complex returns chain up to 13 skills together. Fix one skill and the improvement propagates across every jurisdiction that uses it.
Three steps. Your AI agent does the work. A real accountant reviews the result.
Your AI coding agent (Claude, Cursor, Codex) pulls the relevant skills from the OpenAccountants library. Transaction classification, vendor recognition, jurisdiction routing.
Skills chain together automatically. Federal feeds into state. Deductions propagate. Every line cites the statute it relies on. Conservative where ambiguous.
The output is professional-grade working papers. Not consumer tax software. A licensed accountant reviews, adjusts if needed, and signs off. Human judgment where it matters.
Every tax jurisdiction. Every statute cited. Every computation verifiable. Open-source, agent-native, and built by accountants who know what a CPA actually needs to sign off.
