The Claim
Nothing you enter is sent anywhere. The calculation runs in your browser and nothing is stored or transmitted.
Select a jurisdiction and enter the date the payment claim was served.
The statute sets the floor. Your contract sets the trap.
Most of these periods can be shortened by the contract, and a contractual notice regime sitting alongside the statutory one can extinguish an entitlement long before any of these deadlines arrive. Contract Risk Intelligence reads the contract and tells you which clauses carry that weight, what they do to you, and what position to take before you sign. Transparent pricing. No demo required.
Nothing is collected
No sign-up, no email, no tracking of what you enter. The calculation runs in your browser.
Indicative only
Dates are a guide. Check them against the legislation and your contract before you rely on any of them.
Not legal advice
This tool counts business days. It does not assess whether your claim is valid or your entitlement is made out.
Disclaimer — Payment Claim Timing Calculator
This disclaimer is specific to this calculator and is in addition to the general disclaimer covering all PiVOTiQ free tools, which applies in full. Security of payment deadlines are unforgiving and a missed date can extinguish a claim entirely. Read this section before relying on any date shown.
This calculator counts business days. It does nothing else
It takes a date you enter, applies a statutory period, and skips weekends, public holidays and any applicable industry shutdown. Every date it produces is the output of that count.
It does not assess whether your payment claim is valid, whether it was properly served, whether it was served on a date the Act permits, or whether the amount claimed is recoverable.
The service date you enter is assumed to be correct and effective
The calculator counts from the date you say the claim was received by the respondent. It cannot verify that the claim was validly served, and service disputes are common. Queensland courts, for example, have held that service by download link rather than as an attached document may be invalid.
If the service date is wrong, every date produced is wrong.
Reference dates are not modelled
Queensland, South Australia and Tasmania retain reference dates, which constrain when a payment claim may validly be served in the first place. New South Wales, Victoria and Western Australia have abolished them and operate on a monthly or contractual basis instead.
This calculator starts from the date you say the claim was served. It does not check whether the claim could validly have been served on that date, and it does not apply the one-claim-per-reference-date limit.
Some adjudication windows are shown as unconfirmed, and that is deliberate
Where the underlying statutory reference does not record an adjudication application period, the calculator displays “not confirmed” instead of a date. Those fields have not been filled from secondary sources.
Treat an unconfirmed field as an instruction to check the Act, not as an indication that no deadline applies. A deadline exists — this tool simply does not assert what it is.
Public holidays are current to a fixed period and exclude regional holidays
Holiday dates are taken from the Fair Work Ombudsman lists for 2026 and 2027 and cover statewide and capital-city holidays only. Regional holidays — the Royal Queensland Show, the Royal Hobart Regatta and Show, Recreation Day, the Friday before the AFL Grand Final, and regional variations to other holidays — are not applied.
This is deliberate. Applying a holiday that does not operate in your area would push a deadline later than it truly is. Omitting one that does operate makes the calculated date earlier, which is the safer direction of error. Where a regional holiday applies to your project, the true deadline may be later than shown — but never earlier.
Where a calculated date falls outside the years for which holiday data is held, the calculator says so. Do not rely on a date carrying that warning.
Contractual periods are applied only where the Act allows
Where you enter a period from your contract that is shorter than the statutory one, it is applied, because the legislation generally operates on the earlier of the two. Where you enter a longer period it is ignored, because a term purporting to extend a statutory timeframe is of no effect.
The calculator does not verify that you have identified the correct contractual provision, and it does not consider whether the contract's own definition of a business day differs from the Act's — a mismatch that has been held capable of shortening a payment schedule deadline.
Not every jurisdiction or contract is covered
The Western Australian periods apply only to construction contracts entered into on or after 1 August 2022. Earlier contracts run under the former provisions, a materially different model this calculator does not cover.
The Northern Territory operates on a different statutory model and is not calculated. The Australian Capital Territory is not calculated because verified periods are not held for it.
In Victoria, the reforms that commenced on 15 April 2026 do not apply to payment claims served before that date, or to adjudication applications not yet determined. Check whether your claim pre-dates the reform.
Contractual notice regimes operate independently
A construction contract commonly contains its own notice provisions with their own deadlines, entirely separate from the statutory scheme. Those provisions can extinguish an entitlement long before any statutory deadline arrives, and this calculator says nothing about them.
Meeting every date shown here does not mean the contractual position is protected.
