Roller Coaster Depreciation in Tax Court: Section 179 and Recapture

A roller coaster is depreciated as two separate assets: the mechanical ride (track, cars, motors, brakes, controls, themed facades) is seven-year tangible personal property under MACRS asset class 80.0, while the concrete footings, grading, drainage, and permanent anchor points beneath it are fifteen-year land improvements under asset class 00.3.¹ For rides placed in service after January 19, 2025, the equipment portion is also eligible for 100 percent bonus depreciation under the One Big Beautiful Bill, so the entire cost of the ride components can be written off in the first year.² The split matters because it determines which dollars get the fast write-off and which spread across fifteen years.

What Counts as the Ride and What Counts as the Land

Federal law assigns every depreciable business asset a recovery period ranging from three to fifty years.³ For a coaster, the sorting looks like this:

Seven-year property (asset class 80.0): the track steel, passenger cars, motors, braking systems, control electronics, safety systems, and themed facades. These are Section 1245 tangible personal property.
Fifteen-year property (asset class 00.3): concrete footings, poured foundations, excavation and grading, drainage, and permanent steel anchor points. These are Section 1250 depreciable real property.⁴

The temptation on installation is to treat the entire construction invoice as one asset and depreciate all of it over seven years. The IRS expects otherwise. If an examiner reclassifies part of a ride from seven-year to fifteen-year property, the underpayment can carry a 20 percent accuracy-related penalty on top of the additional tax.⁵

Why the Ride Itself Qualifies as Equipment

The framework courts use comes from Whiteco Industries, Inc. v. Commissioner, 65 T.C. 664 (1975), which set out six factors for deciding whether something is tangible personal property or a permanent structure:⁶

Mobility: can the property be moved, and has it been moved?
Design intent: was it built to stay permanently in one place?
Expected duration: are there circumstances suggesting it might be relocated during its useful life?
Difficulty of removal: how substantial is the job of taking it apart?
Damage on removal: how much damage would the property sustain if removed?
Manner of attachment: how is it physically connected to the land?

Federal regulations reinforce this framework by defining tangible personal property as anything other than land, buildings, and structural components of buildings.⁷ A coaster track propels passengers at high speed through a programmed course; it does not shelter anything. In Wild River Country and similar cases, the Tax Court applied the Whiteco factors to amusement rides and concluded that ride components function as machinery. They experience mechanical wear from operation, they can be disassembled and relocated when parks reconfigure, and their purpose is kinetic rather than structural.

No single factor decides the question. A ride can be bolted to concrete footings and still qualify as equipment when the other factors point toward a purpose-built machine. The favorable treatment stops at the ground because foundations are poured into the earth with no intention of removal. When a park replaces a coaster, the old foundations are typically demolished or left in place rather than moved, and that permanence is what puts them on the fifteen-year schedule.

Bonus Depreciation and Section 179 Under Current Law

The seven-versus-fifteen debate mattered most when operators had to spread deductions across the full recovery period. That changed in 2025. The One Big Beautiful Bill restored 100 percent bonus depreciation for qualifying business property placed in service after January 19, 2025, and the IRS has issued interim guidance instructing taxpayers to apply existing depreciation rules with the updated percentages and dates.⁸ A park installing a new coaster in 2026 can deduct the entire cost of the seven-year ride components in the first year.

Bonus depreciation applies to both new and used property, as long as the asset is new to the taxpayer. Taxpayers who prefer to spread the deduction can elect a reduced 40 percent first-year bonus instead of the full 100 percent for the first tax year ending after January 19, 2025.³ Fifteen-year land improvements are also eligible for bonus depreciation under the statute, so the foundation portion is not stranded. The classification split still matters, though, because it determines which dollars follow which depreciation method if a taxpayer elects out of bonus for one class but not the other.

Section 179 offers a separate first-year expensing option. For 2026, the deduction limit is approximately $2,560,000, with a phase-out beginning when total qualifying purchases exceed roughly $4,090,000. Section 179 covers only tangible personal property, so only the ride components qualify. On a multimillion-dollar coaster, Section 179 alone will not cover the full cost, but it can carry the day for smaller rides and upgrades.

Cost Segregation: How to Make the Split Defensible

The practical mechanism for separating the ride from the foundation is a cost segregation study. An engineering-based analysis breaks a single construction project into its component parts and assigns each part to the correct asset class. For a coaster, the study separates track steel, cars, motors, brakes, and controls (seven-year) from footings, grading, drainage, and anchor bolts (fifteen-year).

The IRS has published a detailed Cost Segregation Audit Technique Guide that examiners use to evaluate these studies, so a sloppy or undocumented analysis will not survive scrutiny.⁹ A credible study includes site visits, construction blueprints, and detailed cost calculations that tie each line item to a specific asset class. Fees range from a few thousand dollars for a straightforward project to considerably more for complex theme-park installations, and the tax savings on a multimillion-dollar ride typically dwarf the fee.

The recordkeeping starts at construction. Invoices should separate excavation, concrete, and anchor systems from track, cars, motors, and control systems. Reconstructing that split years later, from memory and a stack of change orders, is the kind of exercise that keeps accountants up at night. Without a clean breakdown, an auditor will do the allocation, and the taxpayer rarely likes the result.

Recapture When the Ride Is Retired

Faster depreciation is not free money. When a park sells or scraps a fully depreciated ride, the gain up to the total prior depreciation is taxed as ordinary income under Section 1245, not at the lower capital gains rate.¹⁰ A park that took 100 percent bonus on a $15 million coaster and later sells the ride components for $2 million recognizes the entire $2 million as ordinary income.

For the foundation portion classified as Section 1250 property, the rules are more forgiving. Only the excess of accelerated depreciation over straight-line is recaptured as ordinary income; any remaining gain is capital gain.⁴ Since land improvements for amusement rides generally use straight-line depreciation, Section 1250 recapture is often minimal. The ride components carry the full recapture exposure.

The upfront deduction is almost always worth it because of the time value of money, but the eventual bill on disposal is the trade-off worth pricing in.

Reporting on Form 4562 and the Mid-Quarter Trap

All MACRS depreciation flows through IRS Form 4562. Ride components placed in service during the current tax year go on Lines 19a through 19j of Part III as seven-year property using the 200 percent declining balance method, or the full bonus deduction if elected.¹¹ The foundation portion goes on a separate line as fifteen-year property using straight-line. Previously placed rides still being depreciated show up on Line 17 as a lump sum carried from the prior-year schedule.

Watch the timing rule. If more than 40 percent of all depreciable property placed in service during the year comes online in the last three months, the mid-quarter convention replaces the standard half-year convention for every asset placed in service that year.³ Large rides often come online late in the season, exactly when this trigger bites, and the mid-quarter convention can shrink the first-year deduction on every asset the park placed in service that year. When a coaster opens deserves advance planning, not a scramble in January.

Gain or loss on the disposal of a ride is reported on Form 4797, with the ordinary-income portion from Section 1245 recapture flowing to the business’s income tax return. A cost segregation study kept alongside the original construction records makes both the annual reporting and the eventual disposal filing straightforward.
