Security of payment deadline calculator

Served or received a payment claim? Here is every statutory deadline that just started running.

Building and Construction Industry Security of Payment Act 1999 (NSW)

Dates skip weekends and national public holidays, plus 27 to 31 December as the Act requires. State public holidays are not included, so check days that land near one.

Deadlines under the NSW Act

Payment schedule due from the respondent

Thu, 30 July 2026

10 business days after date you served the payment claim · s 14(4)

Or the time the contract requires, whichever is earlier. No schedule by then means the respondent is liable for the full claimed amount.

Payment due if you are a head contractor claiming on the principal

Thu, 6 Aug 2026

15 business days after date you served the payment claim · s 11(1A)

The contract can only make this earlier. Exempt residential contracts follow the contract instead (s 11(1C)).

Payment due if you are a subcontractor

Thu, 13 Aug 2026

20 business days after date you served the payment claim · s 11(1B)

The contract can only make this earlier.

Adjudication: schedule offered less than you claimed

10 business days

10 business days after you receive the payment schedule · s 17(3)(c)

Adjudication: scheduled amount not paid

20 business days

20 business days after the due date for payment · s 17(3)(d)

No schedule at all: notify intention to adjudicate

20 business days

20 business days after the due date for payment · s 17(2)(b)

The respondent then has 5 business days to provide a schedule; apply within 10 business days after that period ends (s 17(3)(e)).
