What Qualifies for Bonus Depreciation: A Complete Tax Guide for Business Owners

What Qualifies for Bonus Depreciation Under IRS Rules

Business owners and tax professionals frequently ask what qualifies for bonus depreciation when planning major asset purchases. Bonus depreciation is a tax incentive that allows qualifying businesses to deduct a significant portion of an eligible asset’s cost in the year it is placed in service, rather than spreading deductions across multiple years through standard depreciation schedules. Understanding the IRS eligibility rules is essential for accurate tax planning and compliance.

Bonus Depreciation Basics

The Tax Cuts and Jobs Act of 2017 dramatically expanded bonus depreciation eligibility, broadening which assets qualify and who can claim them. However, the rules have changed since then, and the phase-out schedule means that eligibility and deduction amounts are shifting year by year. If you are a business owner wondering whether a recent purchase qualifies, or if you are planning a capital investment, understanding the current IRS framework is the first step.

This guide walks through the core IRS requirements for bonus depreciation, eligible property categories, important exclusions, and how recent tax law changes affect what you can deduct today. Whether you are a small business owner, a real estate investor, or a corporate taxpayer, this resource provides foundational knowledge to help you approach bonus depreciation decisions with greater confidence.

Core Requirements for What Qualifies for Bonus Depreciation

Original Use or Acquisition Requirements

Historically, bonus depreciation only applied to new property where the taxpayer was the original user. The Tax Cuts and Jobs Act changed this significantly. Under current rules, used property can also qualify for bonus depreciation, provided the taxpayer has not previously used the property and has not acquired it from a related party or through certain nontaxable transactions. This change opened bonus depreciation eligibility to a much broader range of acquisitions, including the purchase of existing equipment, machinery, or qualifying components from third parties.

Placed-in-Service Requirement

The asset must be placed in service during the applicable tax year. Purchased but not yet operational equipment does not trigger a bonus depreciation deduction. The IRS defines “placed in service” as the point when the asset is in a condition and state of readiness to be used for its intended purpose in the trade or business. Simply receiving delivery of equipment is not sufficient if it has not yet been made operational.

Depreciable Life Threshold

To qualify for bonus depreciation, property generally must have a recovery period of twenty years or less under the Modified Accelerated Cost Recovery System, also known as MACRS. This threshold captures a wide range of business assets but excludes longer-lived real property such as buildings. Certain specific categories, discussed further below, receive special treatment.

Business Use Requirement

The property must be used in a trade or business or for the production of income. Personal use assets do not qualify. If an asset is used for both business and personal purposes, only the business-use portion of the cost basis is eligible for bonus depreciation.

Eligible Property Categories: What Qualifies for Bonus Depreciation Across Asset Types

Tangible Personal Property

This is the most common category for bonus depreciation claims. Tangible personal property includes machinery, equipment, computers, office furniture, and vehicles used in a trade or business. These assets typically have MACRS recovery periods of five or seven years, placing them comfortably within the eligibility threshold.

Examples include manufacturing equipment, medical devices used in a practice, restaurant equipment, retail fixtures, and technology hardware. When these assets are purchased and placed in service during the tax year, they generally meet the core criteria for bonus depreciation eligibility.

Qualified Improvement Property

Qualified Improvement Property, commonly referred to as QIP, refers to improvements made to the interior of a nonresidential commercial building that has already been placed in service. The improvement must be made after the building was first placed in service. QIP specifically excludes enlargements of a building, elevators or escalators, and internal structural framework.

A technical correction made through the CARES Act in 2020 assigned QIP a fifteen-year recovery period under MACRS, making it eligible for bonus depreciation. This correction was retroactive and resolved a drafting error in the original Tax Cuts and Jobs Act language. Businesses that made qualifying interior improvements to commercial property may now claim bonus depreciation on those costs.

Listed Property

Listed property is a special category that includes assets with significant potential for personal use, such as passenger automobiles, computers used outside a business setting, and certain entertainment property. The IRS applies strict substantiation rules to listed property, and business use must exceed fifty percent for the property to qualify for bonus depreciation.

Passenger automobiles are subject to additional annual deduction limits under the luxury automobile rules, even when bonus depreciation applies. This means that while a vehicle may qualify for bonus depreciation, the actual deduction available may be capped under separate IRS limitations.

Film, Television, and Live Theatrical Productions

Qualifying film, television, and live theatrical productions placed in service after the Tax Cuts and Jobs Act are eligible for bonus depreciation. The production must meet specific IRS requirements related to compensation paid to performing artists and where the production is created. This category reflects Congress’s intent to support domestic media and entertainment industries through accelerated deductions.

Common Tax Challenges: Property That Does Not Qualify for Bonus Depreciation

Real Property Structures

Buildings and structural components generally do not qualify for bonus depreciation because their MACRS recovery period exceeds twenty years. Residential rental property has a twenty-seven-and-a-half-year recovery period, and nonresidential real property has a thirty-nine-year recovery period. Neither category meets the eligibility threshold.

However, certain components of real property may qualify separately. Cost segregation studies identify and reclassify elements of a real property acquisition or construction project into shorter-lived asset categories. This process can significantly expand the amount of property eligible for bonus depreciation within a real estate investment.

Intangible Assets

Intangible assets such as patents, trademarks, customer lists, and goodwill acquired in a business purchase are generally ineligible for bonus depreciation. These assets are amortized under Section 197 of the Internal Revenue Code over a fifteen-year period, but they do not fall within the MACRS framework that governs bonus depreciation eligibility.

Property Used Outside the United States

Property used predominantly outside the United States is generally excluded from bonus depreciation eligibility. This rule affects multinational businesses with international operations that may otherwise expect to claim bonus depreciation on globally deployed assets.

Property Acquired Through Certain Transactions

Property acquired from a related party does not qualify for the expanded used-property bonus depreciation rules. Similarly, property acquired in a like-kind exchange or involuntary conversion only qualifies for bonus depreciation on any additional cost basis beyond the exchanged property’s value.

Step-by-Step Tax: Understanding the Bonus Depreciation Phase-Out Schedule

How the Phase-Out Works

The bonus depreciation deduction percentage began decreasing after tax year 2022. Each subsequent year reduces the available deduction by a fixed increment, with the bonus depreciation benefit eventually phasing out entirely unless Congress acts to extend or reinstate it. This means that while a specific type of property may still technically qualify for bonus depreciation, the percentage of the cost that can be immediately deducted is lower than it was in prior years.

Businesses planning large capital expenditures should account for this phase-out when analyzing the tax impact of purchases. Timing decisions around when to place an asset in service can have meaningful tax consequences.

Electing Out of Bonus Depreciation

Taxpayers are not required to claim bonus depreciation. In some situations, a business may prefer to use standard MACRS depreciation or the Section 179 expensing election instead. For example, businesses with net operating losses may receive limited benefit from large bonus depreciation deductions in the current year. Electing out of bonus depreciation must be done on a class-by-class basis, meaning a taxpayer cannot selectively apply bonus depreciation to individual assets within the same property class.

Interaction with Section 179

Section 179 allows businesses to immediately expense qualifying property, subject to certain annual limitations and phase-outs based on total property placed in service. Bonus depreciation and Section 179 can both apply to the same asset in some cases, with Section 179 applied first. Understanding the interaction between these two provisions is critical for accurate tax planning, particularly for businesses investing heavily in equipment or machinery in a single tax year.

IRS Data: What the Research Shows About Bonus Depreciation Usage

Industries Most Affected by Bonus Depreciation Rules

Businesses that rely on equipment, machinery, and technology purchases are most directly affected by bonus depreciation eligibility rules. Industries with high annual capital expenditure tend to see the greatest tax planning impact from changes to bonus depreciation law. For these businesses, understanding what qualifies for bonus depreciation is not a peripheral tax question but a central element of financial planning.

Cost Segregation as a Bonus Depreciation Strategy

Real estate investors and commercial property owners frequently use cost segregation studies to identify assets within a property that qualify for bonus depreciation. A cost segregation study conducted by qualified engineers and tax professionals can reclassify significant portions of building costs into five-year, seven-year, or fifteen-year property, each of which qualifies for bonus depreciation. The combination of cost segregation and bonus depreciation has allowed real estate investors to substantially accelerate deductions on qualifying property.

Expert Tax Strategies: Working with a Tax Attorney on Bonus Depreciation Compliance

Proper Asset Classification

One of the most common areas of error in bonus depreciation claims involves asset classification. Placing a long-lived structural component in a short-lived property category, or failing to identify a component that genuinely qualifies for reclassification, can result in either missed deductions or overstated claims. Tax professionals with experience in depreciation planning can help ensure that each asset is correctly classified under MACRS before a bonus depreciation claim is filed.

Documentation and Substantiation

The IRS expects businesses to maintain adequate records supporting bonus depreciation claims. This includes purchase documentation, placed-in-service records, business use logs for listed property, and cost segregation reports where applicable. Inadequate documentation is a common audit risk, particularly for businesses claiming bonus depreciation on high-value assets or used property.

Amended Returns and Missed Deductions

If a business failed to claim bonus depreciation in a prior year for qualifying property, there may be opportunities to file an amended return or request a change in accounting method to capture the missed deduction. Tax attorneys can evaluate whether prior-year returns were handled correctly and identify lawful remedies where deductions were overlooked.

Legal Tax Methods: Final Insights on What Qualifies for Bonus Depreciation

Understanding what qualifies for bonus depreciation requires a working knowledge of IRS property classifications, the placed-in-service rules, the used-property acquisition standards, and the ongoing phase-out schedule. Eligible property generally includes tangible personal property with a MACRS recovery period of twenty years or less, qualified improvement property, certain listed property used predominantly for business, and qualifying film and production assets. Real property structures, intangibles, foreign-use property, and related-party acquisitions are generally excluded.

The phase-out schedule adds a time dimension to bonus depreciation planning that cannot be ignored. Businesses with significant capital expenditure plans should evaluate the timing of purchases in light of declining deduction rates. Working with experienced tax counsel ensures that eligibility determinations are accurate, documentation requirements are met, and available deductions are fully and lawfully captured.

Take Action: Evaluate Whether Your Assets Qualify for Bonus Depreciation
