New contractors hear "you need a bond" and think it's just another insurance line item. It isn't. A surety bond is a three-party arrangement that works fundamentally differently from the general liability and workers comp policies you're also going to need. Understanding the difference is the first step to not getting blindsided when a claim hits.
Here's the full picture: what bonds do, what they cost in 2026, and how to qualify without accidentally putting your house up as collateral.
A Surety Bond Is Not Insurance
The simplest way to internalize this: insurance protects you, a bond protects someone else from you.
When you buy a general liability policy, you're paying a carrier to take on the risk of future losses. If a claim is filed and it's covered, the insurer writes a check and absorbs the loss. Your premium reflects the insurer's statistical expectation of how often and how much they'll have to pay.
A surety bond has three parties:
- Principal — you, the contractor
- Obligee — the party being protected (the state, the project owner, or a general contractor)
- Surety — the bonding company that stands behind you
When a valid claim is paid, the surety pays the obligee first, then comes after you for the full amount, plus fees and legal costs. The premium you pay isn't buying coverage; it's the fee for extending you a line of credit backed by your personal indemnity.
This is why surety underwriting looks like bank lending, not insurance underwriting. Sureties care about your credit score, working capital, net worth, and experience — because they're essentially deciding whether to extend you an unsecured loan.
The Four Bond Types You'll Encounter
Most contractors deal with some combination of these four. The rules, cost structure, and qualifying criteria differ for each.
1. License (or Contractor) Bond
Required by most license-heavy states as a condition of being issued or maintaining a contractor license.
- Typical penalty amount: $10,000 to $25,000 (California: $25,000 for general contractors as of 2026; Arizona: $9,000–$15,000 depending on class; North Carolina: $15,000–$25,000 depending on classification)
- Premium: 1%–3% of bond amount for qualified applicants, 3%–10% for substandard credit
- What it guarantees: compliance with state contractor law, payment of civil penalties, and payment of judgments arising from license-law violations
- Who can file a claim: typically consumers, subcontractors, suppliers, or employees injured by the contractor's law violations; rules vary by state
- Term: usually 1 or 2 years, renewable for as long as you hold the license
The license bond is the cheapest and easiest to qualify for. Most one-person shops with decent personal credit can get one without putting up collateral.
2. Bid Bond
Used on public-works and many commercial projects to guarantee that if you're the winning bidder, you'll actually sign the contract and provide the required performance bond. If you back out after winning, the owner can claim the difference between your bid and the next-lowest bid, up to the bid bond penalty.
- Typical penalty: 5%–10% of bid amount, sometimes 100% of bid-to-contract-price difference
- Premium: usually no direct premium for contractors with a pre-qualified surety line; otherwise $100–$500 flat per bid
- Key qualifying criterion: you must be pre-qualified by the surety for a performance bond of the contract amount, since a bid bond commits the surety to eventually issue that performance bond
If you're not pre-qualified with a surety, you can't bid on anything requiring a bid bond — which is most meaningful public work.
3. Performance Bond
Guarantees that you will complete the contracted project per the plans, specifications, and schedule. If you walk off the job or fail to perform, the owner can call the bond and the surety must either complete the work themselves, pay another contractor to complete it, or pay the owner the remaining cost of completion up to the penalty amount.
- Typical penalty: 100% of contract value on public work; 50%–100% on private work
- Premium: 0.5%–2% of contract value for well-qualified contractors; 3%–5% for weaker credit
- Required on: virtually all federal projects (Miller Act), most state and local public work (Little Miller Acts), and many large private projects
4. Payment Bond
Guarantees that you'll pay your subcontractors, laborers, and material suppliers. It exists because on public work, your subs and suppliers can't put a mechanic's lien on a government building — so Congress, via the Miller Act (1935), required prime contractors on federal jobs to post payment bonds so subs have recourse if the prime doesn't pay.
- Typical penalty: 100% of contract value on public work
- Almost always paired with a performance bond — sometimes written on a single combined form
- Claimants: first-tier subs, second-tier subs (with notice), and material suppliers
On federal work, the Miller Act applies to contracts over $150,000 — payment bond required. State "Little Miller Acts" vary; thresholds typically run $100,000–$250,000.
The Three Cs of Bond Underwriting
Sureties evaluate bondable contractors on three axes. Weakness on one can be offset by strength on others; weakness on all three means no bond.
Credit
Personal FICO of the owner(s). The surety pulls a personal credit report on everyone with 10%+ ownership, plus spouses in community property states. 2026 bond market benchmarks:
| FICO Range | Market Tier | Typical License Bond Rate | |---|---|---| | 720+ | Preferred | 0.75%–1.5% | | 680–719 | Standard | 1.5%–2.5% | | 640–679 | Substandard | 2.5%–5% | | 600–639 | High-risk | 5%–10% + likely collateral | | Below 600 | Decline / collateral only | 10%+ and full cash collateral |
Capital
Working capital (current assets minus current liabilities) and net worth. For small license bonds, the surety typically doesn't look closely. For performance bonds over $250,000, expect to provide:
- Two years of business tax returns
- Current interim financial statements (balance sheet + P&L)
- Personal financial statement for each 10%+ owner
- Bank reference letters
- Work-in-progress schedule (WIP) showing current projects and completion percentages
A common rule-of-thumb: sureties want to see working capital of at least 10% of the largest single job they're bonding you for.
Capacity
Your historical track record. Sureties ask:
- How long have you been in business in this trade?
- What's the largest single project you've completed successfully?
- What's your aggregate backlog of work-in-progress?
- Have you ever had a claim paid on a bond?
A single paid claim generally locks you out of the standard market for 3–5 years. A bankruptcy or a felony conviction shuts you out longer.
2026 Cost Expectations
For quick planning, rough 2026 ranges:
| Bond | Penalty | Premium (standard credit) | |---|---|---| | State license bond | $15,000 | $150–$375/year | | State license bond | $25,000 | $250–$625/year | | Small commercial performance bond | $100,000 | $1,000–$2,500 | | Mid-size performance bond | $500,000 | $5,000–$12,500 | | Large performance + payment bond | $2,500,000 | $25,000–$62,500 |
Multi-year license bonds often come with a small discount (2-year term at ~1.8x the 1-year premium).
The Indemnity Agreement — Read It
Every bond is backed by a General Indemnity Agreement (GIA). You sign it once, typically when you establish a surety line, and it covers all bonds the surety issues to you going forward.
Key provisions that catch people off guard:
- Personal indemnity, even if the bond is issued to your LLC or corporation
- Spousal indemnity in community property states (Arizona, California, Texas, Nevada, New Mexico, Idaho, Washington, Wisconsin, Louisiana)
- Collateral on demand — the surety can require you to post cash collateral equal to their reasonable exposure if they suspect a claim is coming, before any loss has been paid
- "Voluntary payment" clause — the surety can pay a claim it considers valid without waiting for your consent, and then come after you for reimbursement
- Attorneys' fees, investigation costs, premiums all reimbursable from you
- "In-kind" completion — the surety can take over your job, hire replacement contractors, and bill you for whatever it costs (not capped at the original contract price)
You are signing over substantial control of your financial life in exchange for bonding capacity. Don't sign a GIA you haven't read or had your attorney look at, especially if the surety is asking for collateral or unusual provisions.
How to Buy Bonds
Three realistic channels:
1. Surety bond agency (specialized broker). This is the default choice for anything above a simple license bond. A good surety agency represents multiple carriers and can place your risk where it'll be priced best. Examples of well-known national surety brokers: Old Republic Surety, NFP, Marsh McLennan Agency, Lockton, Alliant.
2. Online bond marketplace (e.g., SuretyBonds.com, BondExchange, JW Surety). Fast quotes for standard license bonds, especially useful under $50,000. For anything above that or any performance bond, work with a human broker — the underwriting conversation matters.
3. Your commercial insurance agent. Many P&C agents dabble in bonds but aren't specialists. Fine for license bonds; not great for performance bonds on six-figure projects. Ask how much surety business they actually write annually before leaning on them for something material.
Get competing quotes. License bond pricing can vary 2x between carriers for the same applicant, and premium differences on performance bonds scale with project size — worth the effort to shop.
Red Flags That You're Paying Too Much
- Premium above 3% on a license bond despite FICO over 680 and 2+ years in business
- Required cash collateral on a $15,000 license bond (rare at standard credit)
- "Admin fees" above $50 on a simple license bond quote
- An agency quoting only one carrier — means they're not actually shopping your file
The Short Version
Treat a surety bond like a loan, not like insurance. The premium is your fee for access to credit; the indemnity agreement is the loan agreement. If a claim pays, you pay — the surety just fronts the money.
Start with a clean personal credit file. Keep your business books reconciled monthly so you can produce financial statements on short notice. Build a relationship with one surety agency early — they get more valuable as your project size grows, and switching mid-stream is painful if you're already pre-qualified on a backlog.
Once you know what your state requires, run your project revenue through the ProJobCalc bidding tools to make sure your margins absorb the bond premium without cutting into your take-home — bond cost is a real line item, not a rounding error.
