On June 26, 2025, the Open Tax Society hosted its launch webinar for the Open Tax Calendar – an AI-powered, open-source platform designed to simplify and automate global tax due date management.

Tax professionals around the world face the same challenges:
Fragmented tax deadlines across jurisdictions

The Open Tax Calendar (OTC) tackles these issues by providing:
A centralized, open, machine-readable database of tax obligations and deadlines
Structured data exports and APIs for seamless automation
A collaborative platform where the global tax community contributes to and validates shared knowledge
