Payment schedule deadline calculator
Security of Payment deadlines run in business days, which exclude weekends, public holidays and a Christmas shutdown that differs by state. Courts treat them strictly.
Why the service date matters
NSW courts confirmed in 2025 that the deadline runs from when the claim was actually served. A contract clause deeming a later service date may not change it. Serve early, use the contract's address for notices, and keep proof.
Christmas shutdowns
- NSW and QLD: 27–31 December are not business days
- VIC: 22 December to 10 January are not business days (from the 2026 reforms)
