A captive insurance company is a regulated insurance institution, owned by the business or group it insures, created to insure real business risks that the commercial insurance market cannot or will not insure efficiently.
Why this matters:
A captive is not a contract or an account. It is an insurer, with legal obligations, capital requirements, and regulatory oversight.
Example:
A multi-state healthcare operator forms a captive to insure regulatory shutdown and malpractice deductibles that are excluded or inefficiently priced by commercial carriers.
Commercial insurers exclude risks that are systemic, correlated, difficult to price, or prone to mass loss because such risks threaten the solvency of the insurance pool.
Why this matters:
Exclusions are not arbitrary. They are structural limits of market insurance.
Example:
Pandemic shutdown risk is excluded because thousands of insureds experience loss simultaneously, eliminating the ability to pool risk.
Captives exist to insure residual risk, meaning risks that remain after commercial insurance has done what it can sustainably do.
Why this matters:
Captives are not substitutes for commercial insurance. They are complements.
Example:
A business keeps commercial general liability insurance but uses a captive to insure the first $500,000 of each claim as a deductible layer.
Yes. Captive insurance is explicitly recognized under state insurance law, federal tax law, and longstanding judicial doctrine.
Why this matters:
The issue is never legality of captives in general. The issue is whether a specific captive operates as insurance.
Example:
All fifty states regulate insurance, and many have dedicated captive insurance statutes.
Bona fide insurance means the arrangement actually functions like insurance, including underwriting, risk transfer, risk distribution, claims payment, and governance.
Why this matters:
Labels do not matter. Behavior does.
Example:
A captive that issues policies, prices premiums actuarially, and pays claims demonstrates bona fide insurance.
Risk transfer means the financial burden of loss moves from the operating business to the captive, and the captive is obligated to pay when a covered event occurs.
Why this matters:
If the business pays losses anyway, insurance does not exist.
Example:
A captive reimburses a $750,000 deductible after a lawsuit settlement, rather than the operating company absorbing the loss.
Risk distribution means spreading risk across multiple exposures so no single loss determines the outcome of the insurer.
Why this matters:
Without distribution, insurance becomes speculation.
Example:
A captive insures multiple operating subsidiaries and participates in a pool of unrelated insureds so losses are shared.
Fortuity means the insured event is uncertain in timing and occurrence. Insurance cannot cover inevitable or scheduled costs.
Why this matters:
Covering predictable expenses converts insurance into budgeting.
Example:
A cyber breach is fortuitous. Routine software upgrades are not.
Premiums are deductible because they are ordinary and necessary business expenses paid to transfer risk, provided the arrangement is bona fide insurance.
Why this matters:
Deductibility follows insurance substance, not ownership structure.
Example:
Premiums paid to a captive for deductible reimbursement reduce taxable income just like premiums paid to a commercial carrier.
Section 831(b) allows qualifying small insurers to be taxed only on investment income, while underwriting income is not taxed currently.
Why this matters:
Underwriting income represents unresolved risk, not completed performance.
Example:
A captive pays tax on interest earned from bonds but does not pay tax on premiums collected for risks that remain outstanding.
No. It changes timing, not taxability.
Why this matters:
Tax is paid when uncertainty resolves or capital leaves the insurance function.
Example:
When a captive distributes surplus after claims resolve, those distributions may be taxable.
Insurance exists to pay claims. Claims prove that policies trigger, capital moves, and risk transfer is real.
Why this matters:
A captive with no claims over long periods appears untested and invites scrutiny.
Example:
A captive that pays small, routine claims annually appears far more credible than one that never pays any.
Timely notice, documented adjustment, reserve setting, payment under policy terms, and a claims file that reads like any insurer’s file.
Why this matters:
Claims files are often the strongest evidence of insurance substance.
Example:
After a regulatory audit, a captive establishes reserves and pays interruption costs pursuant to policy language.
Premiums must be calculated, not selected, using actuarial methods and exposure data.
Why this matters:
Reverse-engineering premiums to hit limits is a common failure point.
Example:
An actuary analyzes five years of loss data to determine an appropriate premium range.
The domicile is the jurisdiction that licenses and regulates the captive.
Why this matters:
Regulatory credibility depends on domicile oversight and reporting discipline.
Example:
A captive domiciled in Vermont files annual statutory statements and undergoes periodic examinations.
Captives are regulated by state insurance departments, not the IRS.
Why this matters:
Insurance regulation focuses on solvency and claims-paying ability.
Example:
A state regulator reviews reserves, investments, and governance during a routine exam.
Captives must prioritize liquidity and solvency over yield.
Why this matters:
Illiquid investments undermine the captive’s ability to pay claims.
Example:
A captive invests primarily in high-quality bonds rather than private equity.
Related-party loans are heavily scrutinized and often undermine risk transfer.
Why this matters:
Insurance capital is not operating cash.
Example:
A captive avoids lending to its parent company to preserve insurance independence.
A captive is intended to operate over many years, across cycles of loss and calm.
Why this matters:
Short-term captives rarely demonstrate insurance behavior.
Example:
A captive operates for twelve years before entering runoff after risks dissipate.
A compliant captive is a regulated institution that prices, holds, and pays uncertainty over time, allowing tax outcomes to follow insurance reality.
Why this matters:
This framing aligns with how courts, regulators, and examiners think.
Example:
A captive that underwrites, pays claims, maintains reserves, and adjusts premiums quietly demonstrates compliance.
Cost segregation is a tax engineering method that separates parts of a building into components that wear out faster so they can be depreciated faster.
Why this matters:
Buildings do not age evenly. The tax code recognizes this, but only if someone explains it.
Example:
A dental office building contains wiring, flooring, cabinetry, and plumbing that wears out much faster than the structure itself. Cost segregation identifies those components separately.
No. It applies existing depreciation rules more accurately.
Why this matters:
A loophole exploits a gap. Cost segregation applies rules that already exist but are often ignored.
Example:
The IRS allows shorter depreciation lives for certain assets. Cost segregation simply identifies them.
Because some assets lose value faster in reality.
Why this matters:
Depreciation is meant to match tax expense with economic wear.
Example:
A roof lasts decades. Dental chair wiring does not. Treating them the same misstates reality.
Because the knowledge never reaches them.
Why this matters:
This is an access problem, not an eligibility problem.
Example:
Institutional real estate firms routinely use cost segregation. Small practice owners often do not because no one explains it.
Anyone who owns depreciable real property used in a business or income-producing activity.
Why this matters:
This is not limited to large companies.
Example:
A single-location dental practice that owns its building can qualify.
No. Cost segregation can be done on existing buildings.
Why this matters:
Many people assume it only applies at purchase.
Example:
A dentist who bought a building ten years ago can still do a study and catch up depreciation.
It is typically caught up in the current year.
Why this matters:
You do not lose the benefit because you learned late.
Example:
A practice takes a large one-time depreciation adjustment instead of amending prior returns.
Not when done correctly.
Why this matters:
The IRS has published guidance on cost segregation for decades.
Example:
A study prepared by qualified engineers and tax professionals follows accepted standards and is routinely upheld.
A team that understands engineering, construction, and tax law.
Why this matters:
This is not a spreadsheet exercise.
Example:
An engineering-based study analyzes building plans, invoices, and site conditions.
Electrical, plumbing, finishes, specialty systems, and site improvements.
Why this matters:
These components often represent a large portion of total cost.
Example:
Dedicated electrical lines for imaging equipment are depreciated faster than the building shell.
It accelerates deductions, which can free up cash earlier.
Why this matters:
Timing matters in business.
Example:
A practice uses the cash flow improvement to hire staff or invest in new equipment.
No. It mostly changes timing.
Why this matters:
This is about when tax is paid, not whether it is paid.
Example:
More depreciation now, less later. The benefit is time value of money.
Certain components may qualify for accelerated deductions under bonus rules.
Why this matters:
This can significantly amplify timing benefits.
Example:
Qualified assets are depreciated much faster than under standard schedules.
Depreciation recapture rules apply.
Why this matters:
This is not “free money.” It must be planned.
Example:
A practice plans its exit strategy understanding how prior depreciation affects sale taxes.
No. The economics must make sense.
Why this matters:
Professional judgment matters.
Example:
A small warehouse with minimal improvements may not justify the study cost.
Both align tax treatment with economic reality.
Why this matters:
Neither is aggressive. Both correct misalignment.
Example:
Cost segregation recognizes uneven wear. Captive insurance recognizes uneven risk.
Because it is grounded in facts and documentation.
Why this matters:
Substance matters more than labels.
Example:
A study that explains why an asset wears out faster stands up under review.
Yes, often very effectively.
Why this matters:
Dental offices contain specialized infrastructure.
Example:
Sterilization rooms, imaging suites, and specialty plumbing qualify for shorter lives.
That it is aggressive tax planning.
Why this matters:
That misconception prevents people from using a lawful tool.
Example:
Cost segregation is often more conservative than default depreciation assumptions.
As part of long-term capital planning, not a one-off tactic.
Why this matters:
It works best when integrated with broader tax and risk planning.
Example:
A practice coordinates cost segregation with captive insurance and expansion planning.
It means the equipment itself becomes a revenue-producing asset, similar to rental real estate. You are not buying it only to use it. You are buying it to own, lease, and earn income, while using depreciation to manage taxes.
Example
A dentist purchases a $350,000 CBCT scanner through an Equipment LLC. The dental practice leases it for monthly rent. The dentist controls the asset, earns lease income, and depreciates the equipment.
Because separating ownership from operations can improve cash flow, reduce taxes earlier, and isolate risk.
Example
A contractor buys a $600,000 excavator personally or in a leasing entity. The construction company leases it instead of carrying the debt and depreciation on its own balance sheet.
The owner of the equipment—the entity that holds title and bears economic risk—gets the depreciation.
Example
Even though the dental staff uses the CBCT machine daily, the Equipment LLC depreciates it because it owns it and bears obsolescence risk.
The IRS looks at benefits and burdens of ownership, not labels.
They ask:
Who owns the title?
Who benefits if the equipment holds value?
Who loses if it becomes obsolete?
Is ownership guaranteed to transfer?
Example
If a contractor’s lease ends with automatic ownership transfer, the IRS may say the contractor—not the leasing entity—was the true owner all along.
Section 179 is intended for equipment used directly in the taxpayer’s active business, not equipment held primarily to generate rental income.
Example
If your Equipment LLC’s only role is to lease machinery, Section 179 is usually disallowed—but bonus depreciation is still available.
Because bonus depreciation follows ownership, not usage, as long as the lease is a true lease.
Example
A $500,000 crane qualifies for bonus depreciation even though it is leased to another company, because the leasing entity owns it.
It depends on the year’s bonus percentage and asset class life.
Example
$400,000 equipment
60 percent bonus depreciation = $240,000 year one
Remaining $160,000 depreciated under MACRS
When the equipment is placed in service—meaning it is ready and available for use.
Example
A dental milling machine installed and calibrated on December 20 qualifies for depreciation that year, even if patients are scanned in January.
The lease must reflect real economics.
Key features:
Market rent
No bargain buyout
No automatic transfer
Lease term shorter than useful life
Owner keeps residual risk
Example
A five-year lease on equipment with a ten-year life is reasonable. A ten-year lease with a $1 buyout is not.
Lease payments must reflect fair market rental value.
Example
If similar equipment leases for $7,500 per month, charging your operating business $7,000–$8,000 per month is defensible. Charging $2,000 is not.
Yes. Lease payments are ordinary income.
But depreciation and expenses usually reduce or eliminate taxable income in early years.
Example
Annual rent received: $90,000
Depreciation and expenses: $140,000
Taxable result: $50,000 loss
Yes, and this is one of the main benefits.
Example
You receive $90,000 in rent in cash, but report a loss due to depreciation. Cash increases while taxes decrease.
Yes. Financing does not prevent depreciation as long as ownership is retained.
Example
A dentist finances 80 percent of a $300,000 scanner. The Equipment LLC still depreciates the full $300,000 purchase price.
Typical deductions include:
Depreciation
Loan interest
Insurance
Repairs the owner pays
Property tax if applicable
Administrative costs
Example
Insurance of $4,000 and maintenance of $6,000 are deductible alongside depreciation.
Yes, but related-party leases are examined closely.
Rules:
Written lease
Market rent
Actual payments
Separate bank accounts
Example
A contractor’s leasing entity invoices the construction company monthly and receives payment just like an outside lessor.
No, when done properly. This is standard commercial leasing practice.
Example
Banks and equipment leasing companies use this exact model at scale with IRS acceptance.
Depreciation recapture applies.
Example
You depreciated $250,000 and sell the equipment for $200,000. Some or all of that gain is taxed as ordinary income.
No. It shifts tax timing.
Example
You saved taxes when cash mattered most and may repay later after years of income generation.
Equipment that is:
Dentist examples
CBCT scanners, CAD/CAM mills, imaging systems
Contractor examples
Cranes, excavators, loaders, specialized trucks
Treating this casually instead of structurally.
Example
Poor lease language or unrealistic rent can cause the IRS to recharacterize the deal and disallow depreciation.
The R&D tax credit is a federal and state incentive that rewards businesses for improving products, processes, or technology—even if the improvement is incremental.
Example
A home services company redesigns how it schedules crews to reduce drive time and fuel usage. That internal process improvement may qualify as R&D.
No. You only need to be developing something new or improved to your business.
Example
A contractor tests different materials and installation methods to improve durability. Even though others use similar methods, it is new to their operation.
Activities involving experimentation, testing, iteration, or technical problem-solving.
Example
A manufacturing company runs multiple production trials to reduce defects and improve throughput.
The activity must meet the four-part test:
It seeks a permitted purpose
It involves technological uncertainty
It relies on technical principles
It includes a process of experimentation
Example
A dental lab tests different milling speeds and materials to reduce breakage. That experimentation satisfies the test.
Many more than people expect.
Common qualifiers include:
Home services
Construction
Manufacturing
Engineering
Software
Healthcare
Food production
Example
An HVAC company designs and tests new installation layouts to improve efficiency in older homes.
Qualified wages, payroll taxes, supplies used in testing, and certain contractor costs.
Example
An electrician pays technicians to test new wiring configurations. Their wages during testing time may qualify.
Yes. Wages are often the largest component of the credit.
Example
A project manager spends 40 percent of their time troubleshooting new construction methods. That portion of their wages may qualify.
Supplies consumed or destroyed during experimentation qualify.
Example
A contractor tests multiple concrete mixes that are discarded after testing. The cost of those materials can be included.
Yes, including internal-use software in many cases.
Example
A service company builds or customizes software to manage dispatching, routing, or billing more efficiently.
Yes. Success is not required. Attempting and testing is what matters.
Example
A manufacturer prototypes a new component that never goes into production. The testing phase may still qualify.
The credit often equals 5 to 10 percent of qualifying expenses, sometimes more when state credits are included.
Example
A company with $500,000 in qualifying wages and supplies may generate $25,000 to $50,000 in credits.
It is a credit, which directly reduces tax owed dollar-for-dollar.
Example
A $40,000 credit reduces a $40,000 tax bill to zero, unlike a deduction which only reduces taxable income.
Yes. Even companies without income can benefit.
Example
A startup uses R&D credits to offset payroll taxes instead of income taxes.
Yes. Credits can generally be claimed retroactively for up to three years by amending returns.
Example
A contractor discovers qualifying R&D activities from 2021–2023 and files amended returns to recover credits.
No, when done correctly and documented properly.
Example
Well-supported claims with engineering narratives and time allocations are routinely accepted.
Project descriptions, employee time allocation, payroll records, and expense support.
Example
A company documents testing phases, employee roles, and technical challenges faced during development.
Yes. They often stack well with depreciation, cost segregation, and equipment leasing.
Example
A manufacturer claims R&D credits on process improvements while depreciating newly acquired machinery.
That only tech companies qualify.
Example
A plumbing company that designs custom systems for unique buildings may qualify just as much as a software firm.
Not claiming credits they are legally entitled to.
Example
A construction company improves methods every year but never documents or claims the credit.
Tax professionals working with engineers or technical specialists.
Example
An R&D study combines CPA oversight with technical interviews to ensure accuracy and compliance.
