OpenAccountants

Présentation

Connects an assistant to the OpenAccountants library of open-source tax and accounting guides. Topics include income tax, corporate tax, VAT/GST, payroll, crypto, entity formation and cross-border planning. Each guide cites its primary sources and states whether a named, licensed accountant has reviewed it. Tools cover scoping a task, loading guides and sections, searching rules, checking filing deadlines, validating VAT numbers and testing statutory audit exemption.

The server is hosted at a streamable HTTP endpoint and needs no sign-in or API key. A pip package, openaccountants-mcp, is also available for self-hosting. The guides are general reference, not advice. Rates and thresholds should be checked against the official source each guide names.
