The principal — the party required to post the bond — is financially responsible for a surety bond. The principal pays the premium to the surety company, and if a claim is paid out, the principal reimburses the surety for every dollar, usually under a personal guarantee that puts their own assets on the line. The obligee, meaning the government agency, project owner, or other party protected by the bond, pays nothing.
What Each Party Pays
A surety bond involves three parties. The principal promises to perform some obligation. The obligee is the party that will be protected if the principal fails. The surety company backs the principal’s promise with its own financial strength.
Money moves in one direction. The principal pays a premium to the surety in exchange for the bond. The obligee pays nothing because the whole point of the arrangement is to shift financial risk away from the party demanding the guarantee. The surety collects the premium but is not expected to absorb losses — if it pays a claim, it has a contractual right to collect that money back from the principal.
What the Premium Costs
Premiums are quoted as a percentage of the bond’s face value, called the penal sum. The percentage depends on the type of bond and the principal’s financial profile.
- License and permit bonds: roughly 0.5% to 10% of the bond amount per year.
- Contract bonds for construction: typically 1% to 3% on larger projects, sometimes 3% or more on smaller ones.
- Judicial bonds: generally 0.75% to 2%.
Credit history is the single biggest factor moving a principal up or down inside those ranges. A contractor with strong financials and a long bonding history might pay close to 1%, while someone with poor credit or little experience could pay 5% or more for the same bond. Industry, the complexity of the underlying obligation, and any prior claims on previous bonds also affect pricing.
Most bonds require annual premiums to stay active. Some contract bonds tied to a specific construction project are paid once for the project’s duration, and multi-year arrangements exist but are less common. Letting a premium lapse is serious: an expired bond can mean regulatory penalties, loss of a professional license, or breach of a contract.
Why a Surety Bond Is Not Insurance
This is the distinction that explains the whole financial picture. Insurance transfers risk away from the policyholder. File a homeowner’s claim and the insurer pays; you owe nothing beyond your deductible. A surety bond does not work that way.
When a surety pays a claim, it has not absorbed the loss. It has fronted the money on the principal’s behalf, and the principal owes it back. A surety bond functions more like a guaranteed line of credit than an insurance policy. The surety lends its financial standing to reassure the obligee, but the principal remains responsible for any losses. Surety underwriting is built around that fact: companies try to bond only principals who can perform, and they rely on the indemnity agreement to recover whatever they do pay.
The Indemnity Agreement and Personal Liability
Before issuing a bond, a surety requires the principal to sign a General Agreement of Indemnity. That contract is where the real financial exposure sits, and most principals do not fully grasp it until a claim arrives.
The agreement obligates the principal to reimburse the surety for any amount the surety pays on a claim, plus every associated cost: legal fees, investigation expenses, and administrative charges. The obligation runs beyond the business entity itself. Sureties almost always require personal indemnity from the business owners who control the company, and frequently from their spouses as well. If the business fails and cannot repay the surety, the surety wants access to the owners’ personal assets, including jointly held property.
The surety can also demand collateral. If it believes a claim is likely or that the principal’s finances have weakened, it can require the principal to deposit cash or other security against the exposure. Refusing to post collateral when the agreement calls for it can itself trigger default.
This piece catches many first-time applicants off guard. A contractor who forms an LLC specifically to limit personal liability will find the indemnity agreement cuts straight through that protection for purposes of the bond. Anyone signing a General Agreement of Indemnity should assume personal savings, a home, and other assets are on the line if things go wrong.
If a Claim Is Filed
When an obligee believes the principal has failed to meet a bonded obligation, it files a claim with the surety. The surety does not pay automatically. It investigates, contacts the principal for their side, reviews documentation, and evaluates whether the claim has merit.
The principal has the right to dispute the claim during that investigation. A bond claim is not a shortcut for an obligee to collect money the principal legitimately disputes. If the surety concludes there is no liability under the bond, it can deny the claim entirely, and it must explain its reasons to the obligee.
If the surety decides the claim is valid and pays, financial responsibility circles back to the principal through the indemnity agreement. The principal owes the full claim amount plus every dollar the surety spent investigating and resolving it. Failing to reimburse the surety triggers legal action, damages the principal’s credit, and makes future bonds far more expensive or impossible to obtain.
One useful limit: the surety’s maximum liability on any bond is capped at the penal sum stated on the face of the bond. A $500,000 performance bond will never cost the surety more than $500,000, even if actual damages run higher; the obligee absorbs anything above. That cap protects the surety but does nothing for the principal. The principal still owes whatever the surety pays out, plus expenses, and those expenses (attorneys, consultants, investigators) can push the principal’s total obligation close to, or even past, the bond amount itself.
Help for Small Businesses: The SBA Bond Guarantee
Small businesses that cannot qualify for a bond on their own can sometimes get help through the U.S. Small Business Administration’s Surety Bond Guarantee Program. The SBA guarantees a portion of the surety’s loss if a claim is paid, which makes sureties more willing to bond contractors who lack an established track record. The program covers contracts up to $9 million for non-federal projects and up to $14 million for federal contracts.1U.S. Small Business Administration. Surety Bonds
The principal still pays. The SBA charges a fee of 0.6% of the contract price for performance and payment bond guarantees, on top of whatever premium the surety charges.1U.S. Small Business Administration. Surety Bonds More important, the SBA guarantee does not eliminate the principal’s indemnity obligation. If a claim is paid, the principal still owes the surety for the surety’s share of the loss. The program reduces the surety’s risk, not the principal’s.
Deducting Bond Premiums on Taxes
Surety bond premiums paid in connection with a trade or business are generally deductible as ordinary business expenses, treated similarly to other insurance-type costs necessary to run the business. For bonds with multi-year terms where the premium is paid upfront, the deduction is typically spread over the coverage period rather than taken all at once. Keep documentation of premiums paid; for contractors and licensed professionals who carry several bonds at a time, it adds up and is often overlooked.
