Overview
The Tax File Number Verification API validates an Australian Tax File Number (TFN) and date of birth against official Australian Tax Office (ATO) records. Confirm that a TFN is genuine and belongs to the person presenting it — without storing sensitive tax information on your systems.
Key Features
- Validates TFN and date of birth directly against ATO records
- Returns a clear match / no-match result with name comparison detail
- Designed for secure, point-in-time verification — no data is retained
- Fast response times for real-time onboarding and compliance checks
- Available in sandbox and production modes
How It Works
