The two most common bonds in contracting serve fundamentally different purposes. Confusing them — or assuming one covers what the other provides — is one of the most costly misunderstandings a contractor can have. This page explains the difference clearly, with specific examples of when each applies.
Side-by-Side Comparison
| Factor | License Bond | Performance Bond |
|---|---|---|
| Purpose | Guarantees compliance with contractor licensing law | Guarantees you'll complete a specific project per the contract |
| Who requires it | State licensing board | Project owner (client, government agency) |
| When required | At license application; maintained annually | Before work begins on a specific project |
| Duration | Continuous — renews annually | Project-specific — expires at project completion |
| Amount | Fixed by licensing board ($5K–$50K typical) | Usually 100% of the contract value |
| Covers | Permit violations, abandonment, licensing law breaches | Failure to complete project, defective work, contractor default |
| Federal trigger | State licensing requirement | Miller Act: federal contracts over $150,000 |
| Premium basis | Credit score × bond amount | Credit + financial strength + project type × bond amount |
| Typical cost | 1–3% annually of bond face value | 1–3% of contract value (one-time for project duration) |
License Bond: The Standing Credential
Your contractor license bond is like your license plate — you maintain it continuously as long as you hold a contractor license. It doesn't cover any specific project. It covers all your licensed work collectively, and its protection runs to your licensing board and any client who suffers harm from a licensing law violation.
The bond amount is set by your state licensing board — not by your project values. A contractor with $500,000 in annual revenue maintains the same $12,000 Washington State registration bond as a contractor doing $50,000 annually. The bond is a license qualification tool, not a project financial guarantee.
Claims against license bonds arise from: performing work without permits, abandoning jobs after taking deposits, violating the scope of your license classification, misrepresenting your license status, or failing to pay required parties in ways that violate your state's licensing law.
Performance Bond: The Project-Specific Guarantee
A performance bond is issued for a specific contract and guarantees that you will complete that contract according to its terms. The bond amount is the contract value — a $2 million construction contract requires a $2 million performance bond. This is a fundamentally different scale from a license bond.
Performance bonds are required by:
- Federal government: Miller Act requires both performance and payment bonds on federal contracts over $150,000. The surety must be on the Treasury Department's Circular 570 list.
- State and local government: Little Miller Acts require bonds on state/local public works projects — thresholds vary by state ($25,000–$500,000 typical).
- Private owners: Sophisticated commercial clients, real estate developers, and lenders increasingly require performance bonds on private projects, particularly those over $1 million.
If you default on a bonded project, the surety must either pay to complete the work, find another contractor to finish, or pay the penal sum. The surety then pursues you for full recovery under your indemnity agreement.
Payment Bond: The Third Type
Performance bonds are typically paired with payment bonds. A payment bond guarantees you'll pay your subcontractors, laborers, and material suppliers on the bonded project. It protects people in the project's supply chain who have no direct contract with the project owner. On federal work, both performance and payment bonds are required by the Miller Act. On public state work, both are typically required by the applicable Little Miller Act.
Do You Ever Need Both Simultaneously?
Yes — regularly. A licensed contractor who wins a public works project maintains their license bond (for licensing compliance) and obtains a separate project-specific performance and payment bond (for project completion guarantee). These are two completely independent bond relationships:
- License bond: $15,000 continuous bond with your state licensing board as obligee, renewed annually, premium $150–$450/year
- Performance bond: $500,000 project-specific bond with the public agency as obligee, duration = project timeline, premium $5,000–$15,000 for that project
Getting Performance Bond Capacity
Getting a $500,000 performance bond is fundamentally different from getting a license bond. The process requires:
- Establishing a surety relationship 60–90 days before you plan to bid — not after winning a contract
- Submitting a financial package: CPA-reviewed statements, work-in-progress schedule, bank reference, personal financial statements
- Underwriter establishes your bonding capacity (maximum bond they'll write)
- Request a capacity letter before submitting bids that require a bond
Bonding capacity is typically set at 10–15x your working capital for a single project, and 15–20x for aggregate capacity. A contractor with $100,000 working capital typically gets a single project limit of $1–1.5 million.
Frequently Asked Questions
Can I use my license bond as a performance bond for a project?
I only do residential work for homeowners who don't require performance bonds. Do I need to understand this?
Is a bid bond the same as a performance bond?
Bond requirements vary by state, contract type, and project owner. This page is for informational purposes only. Consult a licensed surety agent for advice on your specific situation.
