A payment bond is a may provide that a contractor will pay workers and suppliers

A payment bond is a written promise from a contractor or construction company that they will pay all workers, subcontractors, and material suppliers involved in a project. The bond is backed by a third party—usually a surety company—who agrees to cover the cost if the contractor fails to pay. The surety company charges a premium (typically 1 to 3 percent of the bond amount) for taking on this risk.

Payment bonds exist because construction projects involve multiple parties: the general contractor, subcontractors, laborers, and suppliers. If a general contractor runs out of money or disappears mid-project, workers and suppliers can file a claim against the bond instead of suing the contractor directly. The surety company then investigates the claim and pays out if it is valid.

Payment bonds are most common on public construction projects (government-funded work) where they are often legally required. Private projects may also use them, though less frequently. The bond protects the people doing the work and providing materials—not the project owner or general contractor.

Key Takeaways

  • A payment bond guarantees that a surety company will pay workers and suppliers if the contractor does not, up to the bond amount.
  • Payment bonds are required on most public construction projects and are backed by a third-party surety company, not by the contractor alone.
  • Workers and suppliers file claims directly against the bond if they are not paid, which is faster than suing the contractor.
  • The contractor pays the surety company a premium (usually 1 to 3 percent of the project cost) to issue the bond.

How payment bonds differ from performance bonds

Payment bonds and performance bonds are often issued together but protect different parties. A performance bond guarantees that the contractor will complete the work according to the contract terms. If the contractor abandons the job or does poor work, the surety company will hire another contractor to finish it or pay the difference in cost.

A payment bond, by contrast, only covers payment to workers and suppliers. It does not may provide the quality or completion of the work itself. On public projects, both bonds are typically required. On private projects, owners may ask for a performance bond but skip the payment bond, leaving workers and suppliers with less protection.

When payment bonds are required

Federal law requires payment bonds on all public construction projects funded by the federal government and valued over $100,000. This rule is part of the Miller Act. Most states have similar laws (called "Little Miller Acts") that require payment bonds on state and local government projects, though the dollar thresholds vary by state—some start at $25,000, others at $50,000 or higher.

Private construction projects are not required to have payment bonds unless the contract specifically calls for one. However, project owners, lenders, or unions may demand a payment bond as a condition of the work. Some private developers routinely require them; others do not use them at all.

Who can file a claim against a payment bond

Workers and suppliers who have not been paid can file a claim, but the rules vary depending on whether the project is public or private. On public projects, workers and suppliers can file a claim directly with the surety company without suing the contractor first. On private projects, the rules are stricter—some states require the claimant to sue the contractor first and prove they cannot collect before turning to the bond.

The claim must be filed within a specific time window. On federal projects, claims must be filed within one year of the last day work was performed or materials were supplied. State laws vary; some allow two years or more. Missing the deadline means losing the right to claim against the bond.

A claimant must also prove they actually performed work or supplied materials and were not paid. This usually means providing invoices, delivery receipts, timesheets, or a signed contract showing what was owed.

The payment bond claim process

The process begins with written notice to the surety company. The claimant sends a letter describing the work or materials provided, the amount owed, and proof of non-payment. The surety company then investigates—they may contact the contractor, the project owner, and other parties to verify the claim.

If the surety company agrees the claim is valid, they will pay it up to the bond limit. If they deny the claim, the claimant can sue the surety company in court. The surety company may also try to recover the money from the contractor through a separate agreement (called an indemnity bond).

The timeline for payment varies. Some claims are resolved in weeks; others take months if the surety company disputes the claim or if court action is needed. Claimants should not assume payment is automatic—the surety company will scrutinize the claim and may request additional documentation.

Bond limits and what they cover

A payment bond is issued for a specific dollar amount, usually equal to the full contract price of the project. If the total unpaid claims exceed the bond amount, the surety company pays out the full bond value, and remaining claimants may receive only partial payment or nothing at all.

Payment bonds cover wages owed to workers, invoices from subcontractors and suppliers, and sometimes rental equipment costs. They do not cover the project owner's losses, the contractor's profits, or damages from poor workmanship. The bond is strictly for payment obligations, not performance or quality issues.

Frequently Asked Questions

What happens if the contractor goes bankrupt?

The payment bond still protects workers and suppliers. They can file a claim against the bond even if the contractor has filed for bankruptcy. The surety company is obligated to pay valid claims regardless of the contractor's financial status. This is one of the main reasons payment bonds exist.

Can a project owner file a claim against a payment bond?

No. Payment bonds protect workers and suppliers only. Project owners are protected by performance bonds instead, which may provide the work will be completed. If you are the project owner and the contractor has not paid workers, you are not a claimant—the workers are.

How much does a payment bond cost?

The contractor pays a premium to the surety company, typically 1 to 3 percent of the bond amount. On a $500,000 project, this could range from $5,000 to $15,000. The exact rate depends on the contractor's credit history, experience, and the surety company's assessment of risk.

What if I miss the deadline to file a claim?

You lose the right to claim against the bond. On federal projects, the deadline is one year from the last day of work. State deadlines vary. Once the deadline passes, your only option is to sue the contractor directly, which is slower and riskier if they have no money.

Is a payment bond the same as a lien?

No. A lien is a legal claim against the property itself; a payment bond is a claim against the surety company. On public projects where liens are not allowed, payment bonds are the main protection for workers and suppliers. On private projects, workers can often file both a lien and a bond claim.
