Replay Available: How AI + Open Data Can Transform Global Tax Compliance

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.

If you missed the live session, you can now watch the replay and access the slidedeck below.

Why This Matters

Tax professionals around the world face the same challenges:

• Fragmented tax deadlines across jurisdictions

• Ambiguity in BEPS and local compliance requirements

• Manual, error-prone processes for managing transfer pricing (TP) calendars

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

Speaker

We were joined by:

• Walid Eljaafari, CEO and Lead Data Scientist, Algonomia
