What it is
TL;DRA captive is a licensed insurance company you own that insures your own business's risks. If it qualifies and stays under the §831(b) premium ceiling (about $2.85M for 2026, indexed), the captive pays no federal tax on underwriting profit, only on investment income, while the operating business deducts the premiums it pays in.
The legitimate use case is risk that commercial carriers price badly or won't cover at all: business interruption, cyber, supply-chain, regulatory change, loss of a key customer, deductible reimbursement. A captive lets a profitable business fund those exposures with pre-tax dollars and keep the reserves if the losses never come.
The abusive use case, which the IRS has attacked relentlessly, is a captive that never pays claims, charges premiums unmoored from any actuarial basis, and exists only to move deductible dollars into a tax-favored pool. The line between the two is substance: real risk, real actuarial pricing, real claims handling.
Who it's for
Established, consistently profitable businesses with genuine uninsured or underinsured exposures and at least mid-six-figure pre-tax income to support meaningful premiums.
- ✓Profitable operating company with real risks commercial carriers won't cover well
- ✓Owner who can fund $500k+ of actuarially supportable annual premium
- ✓Business with the discipline to run the captive as a real insurer (claims, audits, filings)
- ✓Multi-entity groups that can pool risk for genuine risk distribution
- ×Owners who want a deduction with no intention of ever paying a claim
- ×Businesses too small to justify the $50k-$150k/yr operating cost
- ×Anyone unwilling to commission an independent actuarial study and feasibility analysis
How it works
1. Run a feasibility and actuarial study first
An independent actuary identifies the insurable risks, models expected losses, and sets premiums that a third party would charge for the same coverage. This study is the spine of the entire structure.
Without defensible actuarial pricing, the premium deduction fails and the arrangement collapses into a disguised dividend.
2. Form and license the captive
The captive is chartered as an insurance company in a captive-friendly domicile (Utah, Tennessee, Delaware, or an offshore jurisdiction with a §953(d) election to be taxed as a U.S. company).
It must be adequately capitalized, maintain reserves, and operate like a real insurer, not a checkbook.
3. Achieve real risk distribution
Insurance requires both risk shifting (the operating company genuinely transfers risk) and risk distribution (the captive pools enough independent exposures that the law of large numbers applies).
Single-entity captives often fail distribution. The Rev. Rul. 2002-90 safe harbor is met by insuring 7+ sufficiently separate subsidiaries, or by participating in a legitimate risk pool.
A captive that never pays a claim is not automatically abusive, but a captive that could not pay a claim, with no reserves, no claims process, and no real risk, is not insurance at all.
4. Make the §831(b) election and operate it
Elect §831(b) so the captive is taxed only on investment income. File the captive's own return, hold annual meetings, process actual claims, and keep the operating company's premium payments current and arm's-length.
A worked example
Reyes Mechanical, a $9M-revenue HVAC and controls contractor in Washington County, carries large warranty, equipment-recall, and project-defect exposures that its commercial policy excludes. An actuary supports $1.1M of annual premium across those risks. Reyes forms a Utah captive and makes the §831(b) election.
| Self-insure with after-tax cash | §831(b) captive | |
|---|---|---|
| Annual premium funded | $1,100,000 | $1,100,000 |
| Deduction at operating company | $0 | $1,100,000 |
| Federal tax on premium at captive | n/a | $0 (underwriting) |
| Operating-company tax saved (≈32%) | $0 | ≈ $352,000 |
| Reserves retained if no claims | $748,000 (after tax) | $1,100,000 |
| Annual tax deferred/saved | ≈ $352,000 |
If the modeled losses never materialize, the captive's reserves grow on a tax-advantaged basis and ultimately distribute to the owner at capital-gain or dividend rates. The catch: every dollar of that benefit depends on the arrangement being real insurance, which is why the actuarial study and claims discipline are non-negotiable.
Limits and risks
Micro-captives are squarely in the IRS's sights. Notice 2016-66 made certain arrangements reportable, and the Tax Court has decided a string of taxpayer losses (Avrahami, Reserve Mechanical, Syzygy) where premiums were unsupported and claims never paid.
The operating cost is real: feasibility study, actuary, captive manager, audits, and annual filings routinely run $50k-$150k per year. Below a certain premium volume the economics don't work.
This is not a do-it-yourself structure. It requires an insurance-law specialist, an independent actuary, and a captive manager, coordinated, not a promoter selling a turnkey deduction.
Captives face among the highest audit scrutiny of any planning structure. The examiner's questions are always the same: were the premiums actuarially justified, was there genuine risk distribution, and did the captive actually behave like an insurer? Independent studies, real claims, and clean separation answer all three; promoter paperwork answers none.
