A payment bond is a may provide from a contractor or supplier that they will pay their workers and material vendors, backed by a third party if they don't
When a construction project or large service contract is underway, the property owner or project manager wants assurance that workers will actually get paid and suppliers won't place liens on the property. A payment bond is a written promise from the contractor to pay everyone involved — laborers, subcontractors, equipment rental companies — and it's backed by a bonding company that steps in if the contractor fails to pay. The bond protects the property owner from liability and protects workers from going unpaid when a contractor runs out of money or disappears.
Payment bonds are most common on public construction projects (schools, roads, government buildings) where they are legally required, but they also appear on large private projects like commercial buildings or major renovations. If you are a worker or supplier on a project with a payment bond, you have a direct claim against the bond if you don't get paid — you don't have to sue the contractor first.
Key Takeaways
- A payment bond is a three-party agreement: the contractor promises to pay, the bonding company guarantees the payment, and the property owner or project manager holds the bond as protection.
- Public construction projects almost always require payment bonds by law, while private projects may or may not have them depending on the contract terms.
- If you work on or supply materials to a bonded project and don't get paid, you can file a claim directly against the bond without suing the contractor first.
- The bonding company investigates your claim and pays it if you meet the bond's conditions, which typically include giving the contractor notice of non-payment and waiting a set period before claiming.
How a payment bond protects workers and suppliers
Without a payment bond, a worker or supplier who doesn't get paid has to sue the contractor personally — a slow and expensive process, especially if the contractor has no money left. With a bond in place, you can file a claim directly against the bonding company, which has the financial resources to pay. The bonding company then pursues the contractor to recover what they paid out.
The bond also gives you leverage before you reach non-payment. If a contractor knows a bonding company is watching and will pay claims, they are more likely to prioritize paying workers and suppliers to avoid damaging their bonding record and losing access to future bonds. On public projects, this protection is mandatory — federal law (the Miller Act for federal projects, and similar state laws for state and local projects) requires payment bonds on most government construction work.
Who is required to post a payment bond
The contractor — the company with the main contract to do the work — is responsible for obtaining and paying for the payment bond. On public projects, the bond is a condition of winning the contract. On private projects, the property owner decides whether to require one, and it is typically written into the construction contract.
The bonding company (also called a surety) evaluates the contractor's financial health, track record, and experience before issuing the bond. If the contractor has a history of payment disputes or poor finances, the bonding company may refuse to bond them or charge a higher premium. The contractor pays the bonding company a percentage of the contract value — typically 0.5% to 3%, depending on the contractor's risk profile and the project size.
What a payment bond actually covers
A payment bond covers wages owed to workers (laborers, equipment operators, supervisors) and invoices owed to suppliers and subcontractors who provided materials or services to the project. The bond does not cover the property owner's costs if the project is incomplete or defective — that is what a performance bond covers. A payment bond is specifically about money owed to people and companies that contributed to the work.
The bond amount is usually set at a percentage of the total contract price — often 100% of the contract value on public projects. This means if the contract is worth $500,000, the payment bond is typically $500,000, so there is enough coverage for all workers and suppliers on that project. If multiple claims exceed the bond amount, they are paid in the order they were filed, and later claimants may receive only a partial payment.
How to file a claim against a payment bond
To file a claim, you will need to contact the bonding company (the surety) directly — not the contractor or the property owner. The bonding company's name and contact information should appear on the bond document itself, which the contractor is required to post on the job site or provide to workers and suppliers who request it. If you cannot locate the bond information, ask the project manager or the contractor's office.
Most bonds require you to give the contractor written notice of non-payment before you file a claim with the surety. This notice period — typically 30 to 90 days depending on the bond terms — gives the contractor a final chance to pay. Keep a copy of this notice and proof that you sent it (certified mail, email with read receipt). After the notice period expires and you still have not been paid, you can file your claim with the bonding company. You will need to provide documentation: invoices, proof of work performed, evidence of non-payment, and copies of your notice to the contractor.
The bonding company will investigate your claim, verify that you are may have access to to payment under the bond terms, and pay you if everything checks out. The timeline varies, but most claims are resolved within 30 to 60 days. Once the bonding company pays your claim, they have the legal right to recover that money from the contractor — either through the contractor's assets or by reducing future bonding capacity.
Payment bonds versus performance bonds
These two bonds serve different purposes and protect different parties. A performance bond protects the property owner if the contractor fails to complete the work or does it poorly — the bonding company will either pay for another contractor to finish the job or compensate the owner for the defect. A payment bond protects workers and suppliers if the contractor doesn't pay them.
On public projects, both bonds are typically required. On private projects, the property owner may require only a performance bond, only a payment bond, or both. If you are a worker or supplier, you care most about the payment bond. If you are a property owner, you care most about the performance bond. In practice, many contractors obtain both from the same bonding company as a package.
What happens if the bonding company denies your claim
If the bonding company denies your claim, they must provide a reason in writing. Common reasons include: you did not follow the notice requirements (you did not give the contractor written notice before filing), you filed after the important date set by the bond terms, you did not provide sufficient documentation of the work or non-payment, or you are not a party the bond covers (for example, you are a sub-subcontractor and the bond only covers direct subcontractors).
If you believe the denial is wrong, you have the right to sue the bonding company to enforce the bond. This is a civil lawsuit and you will need to prove your case — that you performed work or supplied materials, that you were not paid, and that you followed the bond's conditions. Having clear documentation (contracts, invoices, proof of delivery, communications with the contractor) makes this much stronger. Some states also have laws that limit how strictly bonding companies can interpret bond terms, so the rules vary by location.
Frequently Asked Questions
Do I have to sue the contractor before I can claim against the payment bond?
No. A payment bond is specifically designed so you can claim directly against the bonding company without suing the contractor first. You do need to give the contractor written notice of non-payment and wait the period specified in the bond (usually 30 to 90 days), but after that you can file with the surety.
What if the contractor says they paid me but the bonding company has no record?
Bring proof of payment — a cancelled check, bank statement, or receipt signed by the contractor. If you have no proof, the bonding company will likely deny the claim because they cannot verify non-payment. This is why it is important to keep all payment records and get written confirmation when you are paid in cash.
Can I claim against a payment bond if I was hired as an independent contractor, not an employee?
Yes. Payment bonds cover subcontractors and suppliers as well as employees. However, the bond terms may specify which types of subcontractors are covered — for example, only those with a written contract with the main contractor. Check the bond document to confirm you fall within the covered parties.
If the bonding company pays my claim, can the contractor come after me for the money?
No. Once the bonding company pays your claim, you are made whole and have no further obligation. The bonding company then pursues the contractor to recover the money they paid out. The contractor cannot sue you for being paid what they owed you.
How long do I have to file a claim after the project ends?
This varies by bond and by state law. Most payment bonds allow claims for one to three years after the project is complete, but some are shorter. Check the bond document or contact the bonding company to confirm the important date. Do not wait — file as soon as you know you will not be paid.
