Who OpenAccountants is

AI makes tax knowledge abundant. OpenAccountants makes tax work trustworthy.

Tax rules are scattered across authorities, paywalled databases and professional memory. AI can make them easier to access, but access without provenance, maintenance and accountability is dangerous. OpenAccountants is building the open layer between raw law, software and professional judgment.

Tax answers should not be governed only by closed models and private databases.

People increasingly ask software and AI systems questions that once went directly to an accountant. The underlying tax knowledge should stay inspectable, correctable and connected to the professionals who understand it — which is why OpenAccountants is built as an open, source-cited and versioned layer the profession can maintain.

Make tax knowledge open, structured and maintainable.

Anyone should be able to inspect the Guide behind a tax answer. Accountants should be able to review and maintain that knowledge. Software should be able to use it without hiding the source. Professional judgment should remain visible where the facts require it.

Principles

Open by default

Public Tax Guides can be read, downloaded and inspected.

Provenance over confidence

Show the source, version and review record instead of relying on confident language.

Maintenance over one-off research

Tax knowledge needs named responsibility and ongoing updates.

Interoperable access

The same knowledge should work through files, code and the AI you already use.

Humans remain accountable

Automation prepares and applies; professionals judge and review where required.

Who is behind this

MC

Michael Cutajar

Founder, OpenAccountants

I started OpenAccountants because the tax knowledge software and AI increasingly rely on was drifting away from the professionals who actually stand behind it. The aim is straightforward: give accountants an open, public way to inspect, review and maintain that knowledge — and a public review record for the work they do.
