Track payment and holdback as separate questions. Release depends on the applicable statute and the relevant project events.
The Builders' Liens Act
The prompt-payment provisions came into force on 1 April 2025. Check the contract transition provisions and confirm that the work falls within the Act before calculating.
Sections 90–94 deal with payment and non-payment in the chain. The owner’s 28-day payment and 14-day notice windows run from the proper invoice being given.

Why money is retained
Construction lien legislation can require a payer to retain part of a payment as holdback. That retained amount supports the statutory lien framework. The amount, calculation, release conditions and any special treatment must be checked for the jurisdiction.
A contractual retention is not necessarily the same thing as statutory holdback. Label the two clearly in your records.
Payment and release are different decisions
Prompt-payment provisions can be expressly subject to holdback requirements. An ordinary invoice payment date therefore does not establish that all retained money must also be released.
Completion, certification, publication and lien expiry can affect release. Reforms can also change periodic or annual release obligations, so an old project checklist may no longer be enough.
Keep the trigger, not just a predicted date
Record the event and document that support a release calculation. Note whether a lien or dispute affects the amount and whether a separate contract retention remains.
Tiercord Learn’s payment calculator excludes holdback release. Use the source material and qualified advice for the actual release decision.
