Accelerated depreciation can make a business aircraft look cheap on the way in and expensive on the way out. The recapture waiting at sale is the part owners overlook.
A business buys an aircraft, claims a large first-year depreciation deduction, and treats the tax saving as settled. Three years later the aircraft sells for more than its written-down value, and a Section 1245 recapture charge arrives — taxed as ordinary income, not capital gain, and often larger than the owner ever anticipated. The deduction was never forgiveness; it was a timing shift, and the timing eventually reverses. This is a general explanation of how US aircraft depreciation and recapture interact, not tax advice for your situation.
Under the US Modified Accelerated Cost Recovery System (MACRS), an aircraft used in a trade or business is a depreciable asset recovered over a defined class life — commonly five years for many non-commercial business aircraft and seven years for aircraft in certain commercial carriage, before any bonus is applied. MACRS front-loads deductions using declining-balance methods, so the early years carry the heaviest write-offs even without additional incentives.
Bonus depreciation sits on top of MACRS and, in its most generous form, allowed a business to expense a large share of the purchase price in year one. That combination is what made aircraft acquisition so tax-efficient in the peak bonus years: a qualifying buyer could shelter a substantial portion of the cost against business income immediately. The mechanics are unforgiving of assumption, however. Bonus eligibility depends on the aircraft being predominantly used in a genuine trade or business, on the property being of a qualifying type, and on placed-in-service timing that must be documented. A deduction claimed on a shaky business-use footing is a deduction exposed on audit, and the specialist work happens before the aircraft is bought, not after.
This section describes general rules; thresholds and definitions change, and none of it substitutes for advice on your facts.
The headline first-year bonus rate is not fixed. US bonus depreciation has moved through a phase-down, stepping down from 100% toward zero across a schedule of placed-in-service years, with legislative proposals periodically restoring or extending higher rates. The practical consequence is that the same aircraft, bought in two different years, can carry materially different first-year deductions.
| Placed-in-service (illustrative) | Indicative first-year bonus | Remainder via MACRS |
|---|---|---|
| Peak bonus years | ~100% | — |
| First step-down | ~80% | ~20% over class life |
| Second step-down | ~60% | ~40% over class life |
| Later step-down | ~40% | ~60% over class life |
| Further step-down | ~20% | ~80% over class life |
The figures above are indicative and illustrative only; the exact percentages and the years to which they apply are set by legislation that shifts, and any restored higher rate changes the picture again. The point for planning is directional: acquisition timing relative to the prevailing bonus rate can swing a first-year deduction by tens of percentage points of the purchase price, so the placed-in-service date is a tax variable, not merely a delivery detail. Confirm the current schedule with a qualified adviser before relying on any rate.
Depreciation is a deferral, not an exemption, and Section 1245 is the mechanism that collects on the deferral. An aircraft is Section 1245 property, and when you sell it the tax code asks a blunt question: how much of the gain simply reverses depreciation you already deducted? That portion — gain up to the total depreciation and bonus taken — is recaptured and taxed as ordinary income, at rates that can materially exceed long-term capital-gains rates.
The arithmetic is where owners are caught. Consider an aircraft bought for US$20m and depreciated down to a US$4m tax basis. If it sells for US$14m, the entire US$10m gain over basis falls within the depreciation taken and is recaptured as ordinary income — there is no capital-gains treatment on that slice at all. Only gain above the original cost, were there any, would be capital in nature.
| Item | Indicative figure (US$) |
|---|---|
| Original cost | 20,000,000 |
| Depreciation & bonus claimed | 16,000,000 |
| Adjusted tax basis | 4,000,000 |
| Sale price | 14,000,000 |
| Total gain | 10,000,000 |
| Section 1245 recapture (ordinary income) | 10,000,000 |
| Capital gain above original cost | 0 |
Figures are illustrative. The lesson holds regardless of the numbers: aggressive early depreciation lowers basis, and a low basis maximises the recapture on exit.
Every deduction above rests on the aircraft being used predominantly for business, and the US rules police that line closely. An aircraft is listed property, which imposes stricter substantiation and, critically, a qualified-business-use threshold: broadly, business use must exceed 50% for accelerated MACRS and bonus depreciation to apply. Fall below that line and the owner can be forced onto slower straight-line recovery — and, if use drops after a bonus year, face a partial recapture of deductions already taken.
None of these tests is optional, and the disallowance rules routinely surprise owners who assumed a business title on the aircraft settled the matter.
Aircraft tax sits at the intersection of federal depreciation, listed-property rules, FAA operational structure, state sales and use tax, and passenger-imputation formulae — and the disciplines interact. An ownership structure that is clean for FAA purposes can be poor for tax; a structure that maximises the first-year deduction can create a punishing recapture or a personal-use exposure that quietly erodes the benefit. Generalist accountants rarely see enough aircraft to hold all of these in view at once.
A specialist earns their fee before purchase, not after. The decisions that matter — the placed-in-service date against the prevailing bonus rate, the ownership and operating structure, the business-use documentation regime, the exit and recapture planning — are largely fixed at acquisition and expensive to unwind later. The right adviser models the full life of the asset, including the sale, so the recapture is anticipated rather than discovered. This page is general information about how these rules fit together; it is not tax advice, and every point here should be tested against your own facts with a qualified aviation-tax professional and counsel before you act.
We introduce owners to specialist aviation-tax counsel and vetted operators through our Marketplace network, under NDA, and coordinate the acquisition so the depreciation position, business-use documentation and eventual Section 1245 recapture are modelled before you sign — not discovered at sale. Give us the aircraft, the intended use and the jurisdictions, and we assemble the right advisers around one clear picture of the true after-tax cost.

Bonus depreciation remains available but at a rate set by a legislative phase-down that has stepped down from 100% toward zero, with periodic proposals to restore higher rates. The exact first-year percentage depends on the placed-in-service year, so acquisition timing matters. Confirm the current rate with a qualified aviation-tax adviser before relying on any figure.
An aircraft is Section 1245 property, so when you sell it, gain up to the total depreciation and bonus you claimed is recaptured and taxed as ordinary income rather than at capital-gains rates. Because accelerated depreciation lowers your tax basis, a strong early deduction typically maximises the recapture charge waiting at exit.
An aircraft is listed property, so business use must generally exceed 50% to claim accelerated MACRS and bonus depreciation. Personal and entertainment flights are disallowed and must be allocated out, and dropping below the threshold after a bonus year can trigger partial recapture. Contemporaneous flight logs are essential to substantiate the position.
SIFL, the Standard Industry Fare Level, is a US formula that imputes taxable income to an employee who takes a personal flight on a company aircraft. It uses a per-mile valuation rather than charter cost, so the imputed figure is usually modest, but each personal flight must still be tracked and reported to stay compliant.
