Prompt payment laws in construction

7 min read · Updated June 2026

Doing the work is only half the job — getting paid for it on time is the other half. Prompt payment laws exist to keep money moving down the chain from owner to GC to subcontractor. Here's how they work and the levers that actually help you get paid faster. (This is general information, not legal advice — verify the rules for your state and project.)

What prompt payment laws do

A prompt payment statute sets deadlines for payment and often allows interest on late amounts. There are two layers:

  • The federal Prompt Payment Act, which governs federal construction projects.
  • State prompt-payment statutes, which most states have for public projects and, in many states, private projects too.

They typically work by starting a clock: once the owner pays the GC (or once your pay application is approved), the party above you has a set number of days to pay you.

The payment deadlines

Exact deadlines vary by state, by whether the project is public or private, and by your contract — they commonly land somewhere in the range of about 7 to 30 days after the upstream payment or approval, but there's no single national number. The takeaways that matter:

  • The clock usually starts at approval or at upstream payment, not at submission.
  • A clean, correct pay application gets approved faster, which starts that clock sooner.
  • Look up your specific state statute and read your subcontract's payment terms.

Pay-when-paid vs. pay-if-paid

Two clauses in your subcontract decide how owner non-payment affects you. They sound alike and are very different:

ClauseWhat it meansYour risk
Pay-when-paidTiming only — GC pays you within a reasonable time after being paidLower — you still get paid eventually
Pay-if-paidCondition — GC's receipt of owner payment is a precondition to paying youHigher — shifts owner non-payment risk onto you

Pay-if-paid clauses are restricted or unenforceable in some states. Know which one is in your contract before you sign — it determines who eats the loss if the owner doesn't pay.

Retainage release

Many states also regulate retainage — capping the percentage on public work and setting deadlines for releasing it after completion. If your retainage is overdue, your state's retainage or prompt-payment statute may be your lever.

How to actually get paid faster

  • Submit clean pay apps. Math errors and missing backup are the most common reasons a draw stalls. A correct G702/G703 approves faster.
  • Send required lien waivers with the bill. A missing conditional waiver is an easy reason to delay you.
  • Bill on a consistent scheduleand hit the GC's cutoff date — miss it and you wait a whole cycle.
  • Know your statutory deadlineso you can follow up the day it's missed, with the law on your side.

Frequently asked questions

What is a prompt payment act?

A prompt payment law sets deadlines for paying contractors and subcontractors after an invoice or pay application is approved (or after the party above gets paid), and often allows interest on late payments. There's a federal Prompt Payment Act for federal projects, and most states have their own statutes covering public and sometimes private work.

What's the difference between pay-when-paid and pay-if-paid?

Pay-when-paid is about timing: the GC must pay you within a reasonable time after being paid, but must still pay you eventually. Pay-if-paid is a condition: it tries to make the GC's receipt of payment from the owner a precondition to paying you at all, shifting the risk of owner non-payment onto you. Pay-if-paid clauses are restricted or unenforceable in some states.

How long does a GC have to pay a subcontractor?

It depends on the state and the contract — deadlines commonly fall in the range of about 7 to 30 days after the GC is paid or the pay app is approved, but the exact number varies. Check your state's prompt-payment statute and your subcontract.

Can I charge interest on late payments?

Often, yes. Many prompt-payment statutes specify an interest rate on overdue amounts. The rate and whether it applies depend on your state and whether the project is public or private — verify the specifics before relying on it.
