A payment bond guarantees that workers and material suppliers get paid, even if the contractor runs out of money
A payment bond is a promise from a bonding company that if a contractor doesn't pay workers or suppliers, the bonding company will step in and cover those costs. It's not insurance for the contractor—it's protection for the people and businesses that do work or deliver materials on a construction project. When a general contractor or subcontractor fails to pay, the unpaid party can file a claim against the bond and receive compensation directly from the bonding company.
Payment bonds are required on most public construction projects—federal, state, and local government work. Private projects may or may not require them, depending on the owner's contract terms. The bond amount is typically set at 100% of the contract price, meaning if the contract is worth $500,000, the bond covers up to $500,000 in unpaid wages and material costs.
Key Takeaways
- A payment bond protects workers and material suppliers when a contractor fails to pay, with the bonding company covering the unpaid amount up to the bond limit.
- Payment bonds are required on most public construction projects but optional on private work unless the owner's contract requires one.
- To file a claim, you must notify the contractor in writing first, wait a set period (usually 30 days), and then file a formal claim with the bonding company.
- The bonding company investigates your claim and pays valid claims, but can deny payment if you fail to follow notice requirements or if the claim exceeds the bond amount.
- A payment bond is different from a performance bond, which protects the project owner if the contractor abandons the work.
How a payment bond protects you on a construction project
When you work on a construction project—whether as a carpenter, electrician, concrete supplier, or equipment rental company—you're extending credit to the contractor. If the contractor gets paid by the project owner but doesn't pass that money down to you, you're out of pocket. A payment bond removes that risk by making the bonding company responsible for your unpaid invoice.
The contractor pays a premium to the bonding company to issue the bond, usually 1% to 3% of the contract price. That premium is the contractor's cost, not yours. Once the bond is in place, you have a direct claim against it if payment doesn't arrive within the agreed timeframe. This is especially important on large projects where cash flow problems can leave workers and suppliers unpaid for months.
When payment bonds are required and when they're optional
Federal construction projects require a payment bond under the Miller Act. Any construction contract over $100,000 funded by federal money must have both a performance bond and a payment bond. State and local governments have their own threshold amounts—some require bonds on projects over $50,000, others over $250,000. Check your state's public construction law or ask the project owner what the threshold is.
Private construction projects have no automatic requirement. A homeowner hiring a contractor to build a deck doesn't need a payment bond unless they specifically ask for one. However, some private owners—particularly large developers or corporations—require payment bonds on all their projects as a standard contract term. Always ask the project owner or general contractor whether a payment bond is required before you start work.
How to file a claim if you don't get paid
Payment bond claims have strict procedural requirements, and missing a deadline can cost you the entire claim. The first step is to send written notice to the contractor stating that you haven't been paid. This notice must be sent within a specific window—usually 30 to 90 days after your last work or material delivery, depending on the bond type and state law. Send it by certified mail or email with a read receipt so you have proof of delivery.
After the notice period expires (typically 30 days after you send notice), you can file a formal claim with the bonding company. You'll need to provide documentation: invoices showing what you were owed, proof of delivery or work completion, your contract with the contractor, and evidence that you sent the required notice. The bonding company will investigate and either approve or deny your claim. If approved, they'll pay you directly, up to the bond limit.
If the bonding company denies your claim, you can sue them in court, but you must do so within a time limit set by state law—usually one to three years from the date you filed the claim. This is why keeping detailed records and meeting all notice deadlines is critical.
What the bonding company will and won't pay
The bonding company will pay valid claims for unpaid wages, materials, equipment rental, and subcontractor invoices. They'll also cover interest and reasonable attorney fees if your contract or state law allows it. However, they won't pay if you fail to meet the notice requirements, if your claim is for work outside the contract scope, or if the total claims against the bond exceed the bond amount.
If multiple parties file claims and the total exceeds the bond limit, the bonding company distributes the available funds proportionally. Workers' wage claims typically get priority over material supplier claims in many states, so if funds run short, workers are paid first. This is why it's important to file your claim as soon as you're may be able to access—the earlier you file, the better your position in the payment queue.
Payment bonds versus performance bonds: what's the difference
A performance bond protects the project owner if the contractor abandons the work or fails to complete it. If the contractor walks off the job, the bonding company pays for another contractor to finish. A payment bond protects workers and suppliers if the contractor doesn't pay them. Both are often required on the same project, and they serve completely different purposes.
On a public project, you'll typically see both bonds in place. The performance bond ensures the project gets finished; the payment bond ensures you get paid for your part in finishing it. If a contractor fails, the performance bond gets the work done, and the payment bond makes sure you're compensated for what you already did.
What happens if the bond amount isn't enough to cover all claims
If the total unpaid invoices exceed the bond limit, the bonding company pays claims in order of priority until the bond is exhausted. In most states, workers' wages have first priority, followed by material suppliers and equipment rental companies. If you're a subcontractor owed $50,000 and the bond is only $100,000 with $120,000 in total claims, you may receive only a partial payment.
Once the bond is depleted, you can pursue the contractor directly through a lawsuit or mechanic's lien (a legal claim against the property). However, if the contractor is insolvent or has disappeared, collecting from them is difficult. This is why filing your claim against the bond quickly is essential—you want to be early in the payment queue, not last.
Frequently Asked Questions
Do I need to notify the contractor before filing a claim against the payment bond?
Yes. You must send written notice to the contractor that you haven't been paid, usually within 30 to 90 days of your last work or delivery. This notice must be sent by certified mail or documented email. Only after this notice period expires can you file a claim with the bonding company. Missing this step will result in your claim being denied.
What if the general contractor says they paid the subcontractor, but the subcontractor didn't pay me?
You can still file a claim against the payment bond. The bond covers unpaid invoices regardless of where the money got stuck in the payment chain. You'll need to show your contract with the subcontractor and proof that you weren't paid. The bonding company will investigate and pay your claim if it's valid.
How long does it take to get paid after I file a claim?
The bonding company typically has 30 to 60 days to investigate and respond to your claim. If approved, payment usually follows within another 30 days. If denied, you'll receive a written explanation. The entire process can take 2 to 4 months, so don't expect immediate payment.
Can I file a payment bond claim if I'm a homeowner and the contractor didn't pay their workers?
No. Payment bond claims are filed by the unpaid worker or supplier, not by the project owner. If you're the homeowner, you can pursue the contractor directly through a lawsuit or demand letter. Workers and suppliers file claims against the bond themselves.
What if I miss the deadline to send notice to the contractor?
Your claim will likely be denied. The notice deadline is strict and varies by state and bond type—usually 30 to 90 days after your last work or delivery. Once you miss it, the bonding company has grounds to reject your claim. This is why sending notice by certified mail as soon as you realize you won't be paid is critical.
