Maximum contribution base: $65,750.00

Timing: Quarterly guidance

Quarterly due-date guidance

The next due date in the current quarterly model is 28 Jul 2026 for the quarter covering 1 Apr to 30 Jun.

Date-sensitive timing should always be checked against the current ATO schedule if your assumptions or payroll timing change.

Transition: Dated policy signal

Payday Super transition

From 1 Jul 2026, Payday Super is intended to move super timing closer to each payroll event. Keep this worksheet in quarterly mode only if your payroll setup or the law has not changed.

Shown as of 18 Apr 2026. Treasury currently points employers to the intended start date of 1 Jul 2026.

Risk: Late payment exposure

Late-payment risk

Late super can trigger the super guarantee charge, interest, and admin costs. If a payment is at risk, reconcile payroll now and check the ATO late-payment process before lodging or remitting.

Next step: Confirm the due date against the current ATO schedule, then reconcile the estimate against your payroll and fund payment file.
