Highlights

  • Payday Super, which is law and started on 1 July 2026, requires super guarantee contributions to reach an employee's fund within 7 business days after payday.
  • Under the previous quarterly system, employers had until 28 days after the end of each quarter to pay.
  • The ATO's guidance defines the exception narrowly: "Exceptional circumstances are natural disasters and widespread information technology and communication outages."
  • The rules sit in Practice Statement Law Administration PS LA 2026/2, listed on the ATO's legal database on 1 October 2026 under the title "Payday Super exceptional circumstances".

A flood or widespread technology outage can disrupt payroll, but extra time for super contributions is tightly controlled.

What counts as exceptional circumstances

Payday Super, which is law and started on 1 July 2026, requires super guarantee contributions to reach an employee's fund within 7 business days after payday. The super guarantee rate is 12%. Under the previous quarterly system, employers had until 28 days after the end of each quarter to pay. With a 7-business-day window, a disruption lasting only a few days can now be enough to miss a deadline, which is why the exceptions carry more weight. The ATO's guidance defines the exception narrowly: "Exceptional circumstances are natural disasters and widespread information technology and communication outages." The rules sit in Practice Statement Law Administration PS LA 2026/2, listed on the ATO's legal database on 1 October 2026 under the title "Payday Super exceptional circumstances".

How the extended deadline is calculated

The ATO decides whether to make a determination, which applies to a class of employers for a specified period. Employers do not need to apply. If a determination covers an employer and a particular qualifying earnings day, usually the payday, contributions are due by the later of two dates: 20 business days after that qualifying earnings day, or 20 business days after the determination is made. Employers self-assess whether they fall within a determination, and they should keep records showing why. The ATO's own example has a qualifying earnings day of 4 August 2026 and a determination issued on 7 August 2026. Twenty business days after the determination is later than 20 business days after the payday, so the contribution is due by 4 September 2026. In that example, the timing of the determination, made three days after payday, is what pushes the deadline out. Where a determination is made weeks after the event, the extra time is measured from the determination date rather than from payday. The next qualifying earnings day in that example, 18 August 2026, has a deadline of 15 September 2026.

Hypothetical example: a February flood

Business days exclude weekends and public holidays that cover a whole state or territory. Holidays that apply to only part of a state still count. Hypothetical example: assume a New South Wales employer pays staff on Wednesday 3 February 2027, and there are no statewide public holidays in the following weeks. Normal deadline, 7 business days after payday: Friday 12 February 2027. If an ATO determination made on or before payday covers that payday, 20 business days after it: Wednesday 3 March 2027. If the determination is made later, say on Friday 12 February 2027, the deadline becomes 20 business days after that date: Friday 12 March 2027. The dates in this example depend on the assumptions above, including that the determination covers the employer and that payday.

Why an individual payroll problem won't qualify

The most important limit is in the ATO's own guidance: determinations "can't be issued for individual employer circumstances". A widespread outage affecting many employers is a different matter, but only if the ATO makes a determination covering it. Timing of payment also matters in an outage. clearing houses need processing time, while payments sent through the New Payments Platform from 1 July 2026 may reach funds on the same day. Because the test is when the fund receives the contribution, a delay at a bank or clearing house can still result in a late payment if no determination applies.
