For merchants of all sizes in Australia, a crucial deadline loom. The Payment Card Industry Data Security Standard (PCI DSS) version 3.2.1 officially retires on March 31, 2024. This means it's time to transition to the new and improved PCI DSS v4.0 to ensure continued cardholder data security.


Considerations for Merchants

The onus falls on merchants to comply with PCI DSS, the high-level timeline considerations are as follow:

  • Starting from March 2024, all merchant needs to use PCI-DSS 4.0 for their compliance assessment. This involves conducting annual self-assessments or undergoing security audits by a PCI Qualified Security Assessor (QSA) depending on their transaction volume. Proactive planning is crucial for a successful transition to v4.0.

  • Between March 2024 and March 2025, all new PCI-DSS requirements which are around 51 new controls and some changes to the existing control are in place and merchants have a grace period to work toward compliance.

  • Starting on March 2025, Merchants need to be fully compliant with the PCI-DSS 4.0 requirements.

There are some additional requirements for both Payment Processors (payment gateways) and companies with Qualified Security Assessors
