Bonus Depreciation on Used Property: Acquisition and Component Tests
By AE Tax Advisors · Published 2026-08-10 · Updated November 8, 2026.
Some used property can qualify for bonus depreciation. A purchase being new to you is part of the analysis, but it is not the only requirement. Review both the asset and the acquisition.
Separate the building from eligible components
Buying a used building does not make the entire purchase price bonus eligible. Exclude land and identify the building and any properly supported shorter-life assets. Cost segregation classifies costs; it does not waive the bonus rules.
Check the prior-use and acquisition requirements
Review whether the taxpayer or a predecessor previously used the property, related-party restrictions and applicable basis requirements. Carryover-basis transfers and inherited basis require different analysis from an ordinary unrelated cash purchase. Do not assume they receive the same treatment.
Use the relevant dates
The acquisition date, including applicable contract rules, and the placed-in-service date can affect the percentage and eligibility. A later study of an existing property does not reset its service date. Preserve purchase agreements, closing documents and readiness records.
Review exchanges carefully
A like-kind exchange can involve exchanged basis and additional basis with different depreciation treatment. Reconcile the exchange computation and asset allocations before projecting any bonus amount. Subtracting an old basis figure from the replacement purchase price is not a complete eligibility analysis.
Measure usable deductions
After classifying components, apply relevant elections and owner-level loss limits. A qualifying component deduction may be deferred under another rule. State tax treatment can differ, and a future sale may create recapture.
Bring acquisition documents, ownership relationships, prior use information and depreciation schedules to a used-property review. Request an asset-by-asset explanation of eligibility.
Frequently Asked Questions
Does every used building qualify for immediate expensing?
No. Land and the building shell are distinct from potentially eligible components, and acquisition requirements still apply.
Does inheriting a property establish bonus eligibility?
No. Inherited basis is subject to separate eligibility rules and should not be treated as an ordinary qualifying purchase.
