Time Bars Under the SOP Act — Don’t Lose Your Right to Claim

You’ve done the work. Your invoices are unpaid. Now you’re thinking about sending a formal payment claim under the Security of Payment Act—but you’re running out of time and don’t realise it.

This is where most tradies and subcontractors slip up. The SOP Act gives you powerful tools to recover money owed, but those tools come with hard deadlines. Miss them, and your right to claim simply vanishes. No second chances. No extensions.

What Are Time Bars and Why Do They Matter?

A time bar is a legal deadline. Once it passes, you lose the right to take action—full stop. Under Australia’s Security of Payment legislation, time bars exist to force disputes to be resolved quickly and to prevent claims hanging over people’s heads indefinitely.

For subcontractors and small builders, time bars are critical because they’re often quite tight. Unlike ordinary contract disputes, which might sit in court for years, SOP claims operate on a compressed timeline. That’s by design—it’s meant to help smaller players like you get paid faster.

But the flip side is brutal: if you miss the deadline, the SOP Act won’t help you anymore.

The Key Time Bars You Need to Know

Different states have different deadlines, and they vary depending on the type of contract and work. Here’s the essentials:

1. NSW (Security of Payment Act 1999): You must serve a payment claim within 12 months of the last date on which you’re entitled to claim payment for the work. After that, the right to claim is extinguished.
2. Queensland (Building Industry Fairness (Security of Payment) Act 2017): Similar 12-month period applies from the date the work was last carried out or services provided.
3. Victoria (Security of Payment Act 2002): You have 12 months from the date you became entitled to payment (or the last date of work).
4. Western Australia (Construction Contracts Act 2004): 12 months from the date the claimant becomes entitled to payment.
5. South Australia and ACT: Typically 12 months, though the exact trigger date can depend on contract terms.

The message is consistent: 12 months is your window in most states. But don’t assume. The exact start date—whether it’s the last date of work, the date you became entitled to payment, or the date you issued an invoice—matters enormously and can vary by legislation.

Why the Clock Starts Earlier Than You Think

Here’s where tradies often get caught. The time bar doesn’t start when you decide to chase the debt. It starts from the date you actually became entitled to payment for the work—which is usually the date the work was completed or the date specified in your contract.

If you completed a job in January and didn’t get paid, your 12-month clock started ticking in January. If you wait until October to issue a formal payment claim, you’ve only got a couple of months left before your right to claim disappears entirely.

Many subcontractors hold off on formal claims hoping the money will turn up. It rarely does. Those months tick past silently, and suddenly you’re up against a hard deadline with no room to manoeuvre.

The practical lesson: don’t wait. If an invoice is overdue by 30–60 days and you haven’t received payment, start thinking about whether you need to serve a formal payment claim under the SOP Act. The sooner you move, the more runway you have.

What Happens If You Miss the Deadline?

If the time bar expires, you lose the right to use the SOP Act to claim payment. Full stop. You can’t file a payment claim. You can’t pursue fast-track adjudication. Your only option then is conventional legal action (suing in court), which is slower, more expensive, and often not worth it for the amounts subcontractors are typically owed.

Some debtors rely on this. They know that if they can run the clock down, the SOP Act stops working against them. It’s a form of delay tactic, and it’s legal.

That’s why protecting yourself is your job, not theirs.

How to Stay On the Right Side of Time Bars

Here’s the practical approach:

• Track the date you completed each job or milestone.
• If you haven’t been paid within 30–60 days, prepare to serve a formal payment claim.
• Serve the payment claim well before the 12-month window closes—ideally within 6–9 months of the work being done.
• Keep copies of everything: your work diary, emails, invoices, photos of completed work. These back up your claim.
• If you’re unsure about your state’s exact time bar rules, check the legislation or seek advice before the deadline approaches.

Once you’ve served a payment claim, the time bar stops being your problem. The SOP Act takes over, and the respondent (the person who owes you money) has to respond within a set timeframe—usually 10 business days in NSW, for example. The process moves quickly from there.

If you need to file a payment claim, PayClaim can help you prepare and serve it correctly. The process is straightforward and costs a flat fee of $79—well worth it to avoid the risk of the time bar expiring.

The Bottom Line

Time bars under the SOP Act aren’t a trap if you understand them. They’re a motivation to act decisively and on time. You’ve earned the money. You’ve done the work. Don’t let a missed deadline take away your legal right to pursue it.

If you’re owed money and you’re uncertain whether your time bar is still running, the moment to check is now—not in three months.
