See the extra working capital Payday Super may require each payday.
Payday Super moves super from a quarterly hold to a due-date clock. This panel models the cash-flow impact of that shift — peak extra working capital and shortfall pressure — using employee count, average Qualifying Earnings, bank balance and receivables lag.
It is an assumption only. Not advice, not a forecast you file, and it does not change the statutory due date or latest-safe buffer above. Fortnightly, 13-week notional quarter. Harbour does not lodge SuperStream.

Harbour Working Paper
Rule 2026.2.0 · example working paper
Practice working paper — not a lodgement.
Usual window is 7 business days after payday. Tick First contribution for 20 business days when it is a new employee or the first contribution to a new fund. The payday (Qualifying Earnings day) is not counted. Harbour does not decide whether 7 or 20 applies. Method · ATO payment deadlines
On time means the fund has received the money and can allocate it. Paying on the statutory due date via a clearing house is usually late. Method
Not the statutory due date and not an ATO deadline. Harbour subtracts a buffer so the contribution is more likely to be received and allocatable before the legal deadline. Paying on the statutory due date via a clearing house is usually late.
Default unknown clearing house: not sure how fast the rail settles — Harbour subtracts 2 business days. On the calculator that is latest safe 25 Aug when statutory due is 27 Aug (18 Aug payday, 7 business days). Optional known fast rail: 1 business day, so latest safe 26 Aug on that same payday. Still not statute. Confirm with your payroll or clearing house. Harbour does not certify NPP, SuperStream, or on-time arrival. Method
