Open-source tax rules for 100 countries that your LLM can use (github.com)

OpenAccountants has launched a comprehensive open-source library of tax rules applicable to 100 countries, providing AI systems with vetted and reviewable tax knowledge. This platform features 1,903 AI skills covering 229 jurisdictions, including 33 that have been accountant-reviewed, allowing AI models to deliver accurate and source-cited tax information. Users can integrate the library into various AI environments, such as ChatGPT and Claude, significantly enhancing the factuality of responses by fetching verified tax skills rather than relying solely on previously trained data. The availability of this rich, structured knowledge base is crucial for the AI/ML community as it addresses the challenge of accessing up-to-date legal and tax information. By ensuring that each skill is periodically reviewed and validated, OpenAccountants enhances the reliability of AI-generated responses, which is vital for industries relying on accurate compliance and financial data. This initiative advances the integration of AI into professional fields by equipping it with directly citable, credible resources, ultimately fostering greater trust in AI applications in finance and taxation.
