Transcript
- Lucas: So a family with a fifty-million-dollar real estate portfolio — commercial properties, a couple of apartment buildings, maybe a self-storage facility — they're paying four hundred thousand dollars a year in commercial insurance premiums. And they get basically nothing back if they don't file a claim. That premium just disappears into the carrier's pool. Luna: Right, and that's where captive insurance comes in. Instead of handing that money to AIG or Chubb, they create their own insurance company — a 'captive' — and the premium stays within their own structure. Lucas: Exactly. And if today gave you a useful lens on that trade-off — the way these episodes stay ad-free is listener support. If you value that, buy me a coffee dot com slash fexingo. It's a small way to keep the conversations going, and it genuinely matters. Luna: Yeah, absolutely. And we're back to the captive structure — because the magic is that the premium becomes a tax-deductible expense for the operating business, and the captive earns underwriting profit tax-advantaged. Lucas: That's the core insight. The IRS allows a closely held business to deduct premiums paid to a related captive as long as the arrangement represents genuine risk transfer. Under Section 831 of the tax code, a captive that elects to be taxed only on investment income — not underwriting profit — can keep premiums up to two point three million dollars a year in 2026, with that cap adjusted for inflation. Luna: So the family can take that four hundred thousand dollar premium, pay it to their own captive, deduct it from their operating income, and the captive only pays tax on what it earns from investing those reserves. The underwriting profit is essentially tax-free. Lucas: Now, the IRS has gotten sharper on this. The 'economic family' doctrine says that a captive insuring only related-party risk may not constitute true insurance for tax purposes. The standard comes from a 2002 Tax Court case — the 'rent a center' decision — which held that a captive must insure a meaningful amount of third-party risk to qualify. Luna: So families can't just form a shell captive that writes a single policy on grandma's jewelry. The IRS expects a diversified pool of risks — ideally at least thirty percent third-party business, or at least twelve unrelated insureds. Lucas: Right. And that's where the sophistication comes in. A well-structured captive might write workers' comp for the family's construction company, property coverage for the commercial buildings, and then layer in cyber liability or D&O for the family office. You want actuarial defensibility. Luna: And the captive can invest its reserves. Since the captive is domiciled in a jurisdiction like Vermont, Delaware, or the Cayman Islands, the investment rules are more flexible than a commercial carrier. You can allocate to private credit, direct real estate, even art — things a traditional insurer might avoid. Lucas: The returns on those investments compound inside the captive. If the family's operating business has a bad year, the captive can pay a dividend back into the family. But the real prize is the long-term tax arbitrage: deduct the premium at the ordinary income rate, earn underwriting profit tax-free under 831, and only pay capital gains on the investment income. Luna: So what does that look like in practice? Give me numbers. Lucas: Okay. Family with fifty million in assets. They set up a captive in Vermont — cost about fifty thousand to form, fifteen thousand a year in domicile fees, plus maybe twenty-five thousand for an actuarial study and ongoing compliance. So call it ninety thousand in annual overhead. But they're captiving three hundred fifty thousand of that original four hundred thousand premium. Let's say the captive has an eighty percent loss ratio — meaning it pays out two hundred eighty thousand in claims and keeps seventy thousand as underwriting profit. Luna: Seventy thousand tax-free. Plus the investment earnings on the three hundred fifty thousand in reserves — maybe at six percent, so another twenty-one thousand. Net benefit: about ninety-one thousand pre-overhead, or roughly seventy-one thousand after costs. That's a seventeen percent return on the premium they would have just lost to a commercial carrier. Lucas: And that's a conservative year. In a low-claims year, the underwriting profit could be two hundred thousand or more. And because the captive is a separate legal entity, those assets are shielded from creditors of the operating business — within limits. Luna: But there's a time horizon issue. The IRS requires captives to maintain reserves for outstanding claims — you can't just drain the captive every December. Many families think of captives as a ten-year-plus vehicle. The real compounding happens after year five. Lucas: Absolutely. And you need a strong captive manager. I've seen families try to DIY with a standard P&C carrier's fronting arrangement, and it gets messy. The fronting carrier keeps a chunk of the premium, the captive retains the risk, and the net economics get diluted. Better to work with a specialist like Strategic Risk Solutions or Artex. Luna: And there's the regulatory dimension. In 2025, the IRS issued a new practice unit on captive audits — they're looking for 'micro-captives' that are thinly capitalized, or that write high-premium policies for low-probability risks like cyber terrorism. The 831 election is a red flag if the numbers don't match the risk profile. Lucas: So the legitimate play is to insure real, measurable risks — property, liability, workers' comp. Not black-swan events. And you need a licensed actuary to certify the premium as fair and reasonable. That certification is your shield in an audit. Luna: Another angle I've seen work well is the 'group captive' — where several unrelated families pool their risks. Each family puts in, say, two hundred thousand. The group captive achieves diversification, so the IRS is happier, and each family gets a proportional share of underwriting profit. The overhead per family drops, too. Lucas: Yes, group captives are growing fast. The Captive Insurance Companies Association reported that group captives now account for about forty percent of all new captive formations in 2025. They're particularly popular for professional services firms — law firms, medical practices — where the partners want to deduct their malpractice premiums and share in the underwriting profit. Luna: So who should consider a captive? Is it a fifty-million-dollar-plus family only, or can someone with ten million do it? Lucas: I'd say the breakeven is around one hundred fifty to two hundred fifty thousand in annual premium. Below that, the compliance costs eat the benefit. But a family with ten million in assets and a high-risk business — say, a construction company or a manufacturing firm — could easily hit that threshold. The captive doesn't have to cover everything. You can captive just the deductible layer. Say your commercial policy has a one-hundred-thousand-dollar deductible. The captive covers that layer, and the commercial carrier covers the excess. Luna: That's the 'fronted captive' structure, right? The commercial carrier issues the policy, but the captive reinsures the deductible layer. The premium for that layer is still deductible, and the captive earns the underwriting profit on it. Lucas: Exactly. And it avoids the 'economic family' issue because the commercial carrier is an unrelated third party. The IRS has consistently upheld fronted captives as legitimate insurance arrangements. Luna: One last piece: in the current interest rate environment — the ten-year Treasury around four point three percent as of early June 2026 — the investment income on captive reserves is meaningful. A few years ago, when rates were near zero, the tax arbitrage was almost entirely about the immediate deduction. Now, the compounding on the reserve side adds a second engine. Lucas: That's why we're seeing more families re-evaluate their captives. If you set one up in 2019 when rates were low, the investment returns were maybe one and a half percent. Now you can lock in four percent on a ladder of Treasuries. That changes the economics dramatically — adds maybe ten to twenty basis points to the total return of the captive. Luna: And for families that have accumulated significant reserves inside the captive — say, two million dollars after five years — that four percent is eighty thousand dollars a year in investment income, taxed at the captive's rate, which under 831 is only on investment income, not the underwriting profit. Lucas: Which brings up an interesting point: the captive can also serve as a sort of internal bank. If the operating business needs a loan, the captive can lend to it at arm's-length interest rates. That interest income flows back to the captive, and the business gets a deduction. But you need proper documentation to avoid recharacterization. Luna: So the captive becomes a financial hub within the family office — not just an insurance vehicle, but a wealth-building entity. That's a powerful concept. Lucas: It is. And the key is patience. A captive is not a one-year tax dodge. It's a long-term capital accumulation structure. The families that do it well treat it with the same rigor as their operating businesses — annual audits, actuarial reviews, board meetings. The ones that treat it as a checkbox get audited and lose. Luna: I think that's the right note to end on. Captive insurance is a legitimate, powerful tool — but only if you respect the regulatory framework and use it for genuine risk transfer, not just tax games. Lucas: And that's the high-net-worth approach. Build it right, run it well, and let the tax efficiency follow. For next time, I want to look at how ultra-wealthy families are using defined-benefit plans for business owners — another structure where the deduction and compounding can work together. Luna: I'll bring the actuarial tables. See you then.
