Aiwyn Integrates Verified Tax Engine with Anthropic’s Claude

Apr 14, 2026
Aiwyn has joined Anthropic's Claude Connector ecosystem, integrating its AI-native tax calculation engine, Aiwyn Tax, into the Claude platform. The integration enables users to perform verified tax computations and scenario analyses directly within Claude.

Aiwyn has joined the Anthropic Claude Connector ecosystem, announced in a press release, making its AI-native tax calculation engine, Aiwyn Tax (formerly Column Tax), available within the Claude platform.

Through this integration, users can run 1040 tax calculations, perform scenario analyses, and explore tax outcomes in real time inside Claude. The system is designed to provide accurate, verifiable tax computations supported by Aiwyn’s infrastructure, which has processed over one million real-world tax returns.

Aiwyn developed its tax engine following its acquisition of Column Tax in December 2025. The company’s TaxCalcBench framework validates output accuracy across thousands of scenarios, ensuring deterministic results suitable for professional use.

The Aiwyn Tax Connector is now live within Claude, marking an early step toward AI-assisted tax workflows for accounting firms. Aiwyn plans to expand the coverage of its tax engine, deepen integrations within the accounting ecosystem, and embed additional AI-assisted capabilities into its client collaboration platform.
