It is the first question almost every business owner asks: what does captive insurance cost? Sometimes with a raised eyebrow. Sometimes with a spreadsheet already open. Either way, it is a good question, and it deserves a straight answer.
The honest version: forming a captive, just as with any business, costs money. And running one costs money every year, just like any other business. And for the right operation, the economics make those costs look small against what comes back.
What You Actually Pay to Form a Captive
Formation is a one-time cost. It covers legal structuring, domicile selection, regulatory filings, actuarial work, and a feasibility analysis that determines whether your risk profile supports a captive in the first place. Formation costs are material -- they run into the tens of thousands of dollars and scale with the complexity of the structure. The feasibility analysis alone is a meaningful investment, because it requires actuarial modeling of your claims history and pricing of the policies the captive will write.
Domicile matters here. The U.S. has more than 30 captive-friendly domiciles, with Vermont, Delaware, Utah, and Tennessee among the most established. Each has its own fee schedule, minimum capitalization requirement, and regulatory approach. Some offshore jurisdictions -- Cayman Islands, Bermuda -- carry lower formation fees but higher ongoing complexity.
Capitalization is separate from formation fees and is frequently misunderstood. A captive must hold sufficient capital to pay claims. The required amount varies by domicile and by the risks the captive writes, but for a typical small-to-mid-size single-parent captive, initial capitalization of $250,000 to $500,000 is common. In some cases, this requirement can be met through a letter of credit with a bank rather than a direct cash contribution. The important distinction: this is not a cost. It is your money, sitting in a company you own, earning investment income that stays on your balance sheet. When the captive is eventually wound down, that capital comes back to you.
The Ongoing Annual Cost
After formation, a captive has annual overhead. This covers captive management fees, regulatory filings, actuarial reviews, and accounting. Annual costs scale with your premium volume -- the more premium flowing through the captive, the more administration it requires. As a rough frame: for an operation at or near the $250,000 premium threshold, annual overhead is a meaningful line item. For an operation at $500,000 or above, the overhead becomes a smaller percentage of the total picture as the economics improve.
The premiums you pay into the captive are separate from overhead. Those premiums fund the reserve that pays your claims. Those reserves gain interest and compound year after year. The key distinction from commercial insurance: premiums paid to a commercial carrier are gone. Premiums paid into your captive go into a reserve account in a company you own. When claims come in below what you contributed for the year, the surplus stays in your captive. The underwriting profit belongs to you, not to a carrier.
Commercial carriers have operated this way for generations. They collect premium, invest it, keep the return, and pay claims from the pool. It is a great business model for them, particularly when they insure well-run, disciplined companies. A captive puts you on the right side of that selection bias -- you become the insurer and you keep the underwriting profits -- with 3F handling the administration so you never have to.
When the Math Tips in Your Favor
The general qualification threshold is $250,000 or more in annual commercial insurance premiums. Below that level, formation and overhead costs consume too large a share of the savings. Above it, the economics shift.
Here is a directional illustration. A business paying $600,000 per year in commercial premiums -- across property, general liability, workers' compensation, and specialty lines -- is sending $600,000 to carriers who invest it and keep the return. If that business forms a captive and routes premiums through the captive structure, a few things change. The premiums retained in the captive earn investment income. Claims years that come in low generate surplus the business keeps. Over time, the captive accumulates capital that belongs to the owner.
The dollar amounts depend on your claims history, your risk profile, and how your captive is structured. 3F does not promise specific savings figures in a preliminary conversation -- that work belongs in a paid feasibility study. What we can tell you is whether your operation likely clears the threshold and whether the business risk profile fits the structure.
A note on tax treatment: Section 831(b) of the Internal Revenue Code provides favorable tax treatment for small captive insurers, allowing qualifying captives to exclude underwriting income up to the statutory limit. That treatment has been on the books for decades and it is a legitimate planning tool when built around real, documented risk. Captives that do not elect 831(b) -- or that exceed the statutory premium limit -- operate under Section 831(a), which is still very tax-advantaged. The IRS applies less scrutiny to 831(a) structures than to 831(b) arrangements, and a captive can convert from 831(a) to 831(b) treatment as the business grows -- though not in reverse. The Internal Revenue Service finalized regulations in January 2025 treating certain micro-captive arrangements as listed transactions or transactions of interest -- specifically those where tax benefits drove the structure more than risk transfer did. 3F builds captives around real risk, real actuarial work, and regulatory compliance. The tax treatment is a feature of a properly structured captive, not the reason to form one.
What the Analysis Costs You
There are two stages to figuring out whether a captive makes sense for your business.
The first is a coverage review. This is what 3F offers at no charge. We read your current policies -- all of them -- in plain language and identify coverage gaps, under-insured exposures, and red flags that could produce a denial when you need the policy most. Most business owners have never had anyone do this. They have hundreds of pages of insurance documentation they have never opened, governing exposures they have never priced. The coverage review surfaces what you actually have -- whether or not a captive could be the right answer and how it might improve your business' risk exposure.
The second stage is a feasibility study. This is a paid engagement. The formation process and the feasibility study are separate at 3F -- and before you reach the feasibility study, we already know with a high degree of certainty whether a captive is likely to make financial sense for your operation. The feasibility study then goes deeper: it involves actuarial analysis of your claims history, prices the specific policies your captive will write, and models the full picture -- losses, taxes, and cash flow -- showing your operation with and without the captive structure. The policies that come out of the feasibility study are designed specifically for your company and priced to fit your exact needs and objectives.
Most owners who go through a coverage review leave knowing something they did not know before -- about their policies, their gaps, and what their commercial program actually covers. That knowledge is worth having regardless of what comes next.
Start With a Coverage Review
You are not deciding whether to form a captive today. You are deciding whether to let someone read your policies.
A no-cost coverage review from 3F Captive Services looks at your current program and tells you plainly: where you are well-covered, where the gaps are, and whether a captive makes sense for your operation. Worst case, you learn what you actually have. Best case, you find a structure that stops sending your underwriting profit to someone else while reducing the risk your company actually faces.
