How to Automate Canadian T4 Slip Parsing with an API (No OCR Setup Required)

A Canadian article shows how to automate T4 slip extraction with a REST API that turns a base64 PDF into structured JSON.

The workflow returns key fields like employer details, SIN, province, and tax box values for downstream systems.

This approach avoids manual data entry and OCR setup, making payroll and tax processing faster and less error-prone.

It can help HR teams, accountants, mortgage brokers, and other users handle Canadian tax forms more efficiently, including multilingual documents.
