Quick Answer
A guarantee that subcontractors and suppliers will get paid even if the contractor runs out of money.
Definition
Definition
A payment bond is a surety bond that guarantees a contractor will pay its subcontractors, suppliers, and laborers even if the contractor fails to do so. Payment bonds are required on all federal construction projects over $150,000 under the Miller Act, and most states have similar 'Little Miller Act' requirements for state-funded projects. Unpaid parties may file a bond claim against the payment bond rather than pursuing a mechanic's lien on public property.
Context
Why It Matters in Bidding
Payment bonds determine which projects a contractor can even bid, since public work above statutory thresholds requires them and surety capacity caps how much bonded work a firm can carry at once. For subs and suppliers, the payment bond is the primary collection backstop on public jobs where mechanic's liens are unavailable, so verifying bond coverage before signing on is a core risk step.
Example
Example
A supplier owed for materials on a state-funded bridge files a claim against the GC's payment bond within the statutory notice window, since liens cannot attach to public property.

FAQ
Questions Contractors Ask
Who can file a claim against a payment bond?
Subcontractors, suppliers, and laborers who furnished labor or materials but were not paid can claim against the bond. First-tier and many second-tier claimants are typically covered, though remote suppliers may need to provide preliminary notice. Notice deadlines and claimant tiers are governed by the Miller Act or the applicable state statute.
What is the difference between a payment bond and a performance bond?
A payment bond guarantees that subs, suppliers, and laborers get paid. A performance bond guarantees the contractor completes the work per the contract. They are usually issued together on public projects, but they protect different parties: the performance bond protects the owner, the payment bond protects the supply chain.
How do payment bonds affect a contractor's bidding capacity?
A surety underwrites a contractor's financial strength, experience, and backlog to set a single-project and aggregate bonding limit. That limit effectively caps how much public, bond-required work a firm can pursue at once. Maintaining strong financials and a clean track record expands the capacity available for future bids.
