🚀 Why is this Upgrade Required?
The Australian Taxation Office (ATO) is mandating the transition to TLS 1.3 for all Digital Service Providers (DSPs) to enhance the security of Single Touch Payroll data transmissions. TLS 1.2 will be retired by 31st December 2025, making the upgrade mandatory.
This is a compulsory national security uplift for all Digital Service Providers (DSPs) to ensure data encryption, compliance, and alignment with ATO’s prescribed standards.
