Federal tax law has no single real-vs-personal-property definition; each regime carries its own rules. Treas. Reg. § 1.1031(a)-3 controls like-kind, § 1.856-10 controls REIT income classification, and the depreciation regime under § 168 uses asset-class definitions inherited from the former Treas. Reg. § 1.48-1 framework. For rental-activity classification under the passive-activity rules, the operative regulation is Treas. Reg. § 1.469-1T(e)(3).
Real property — the structural test
§ 1.1031(a)-3 defines real property as land and improvements to land (inherently permanent structures and their structural components), unsevered natural products, and water/air superjacent to land. Classification of items not listed turns on (i) manner of affixation, (ii) design for removal vs. permanence, (iii) damage on removal, (iv) expected duration of affixation, and (v) time/expense to move. State law controls only the property-vs-personal-property gating question; the rest of the analysis is federal.
Personal property — the residual
Personal property includes assets not affixed permanently to real property — equipment, vehicles, machinery, furniture, livestock, and most depreciable tangible property in MACRS classes 3, 5, 7, 10, 15, and 20-year. § 168(e) fixes the class life; bonus depreciation under § 168(k) (restored to 100% by OBBBA) applies to most personal property but not real property absent a cost-segregation reclassification.
The § 469 rental-activity test
§ 469(c)(2) treats rental activities as per-se passive regardless of participation, with the exception in § 469(c)(7) for real estate professionals. Treas. Reg. § 1.469-1T(e)(3)(ii) carves six classes of activity out of "rental activity" entirely:
- Average period of customer use is 7 days or less.
- Average period of customer use is 30 days or less and significant personal services are provided.
- Extraordinary personal services are provided regardless of customer-use period.
- Rental is incidental to a non-rental activity of the taxpayer.
- The property is customarily made available during defined business hours for nonexclusive use by various customers.
- The property is provided for use in a non-rental activity of a partnership, S corporation, or joint venture in which the taxpayer is an owner.
An activity caught by one of these is not a rental activity; passive-or-not is decided by material participation under § 1.469-5T rather than per-se passive treatment. The § 1.469-1T(e)(3)(i) "average period of customer use" calculation is the gating issue.
SE-tax boundary
§ 1402(a)(1) excludes rentals from real estate (and personal property leased with the real estate) from net earnings from self-employment, regardless of activity level. Rentals of personal property are not excluded; whether they create NESE depends on whether the activity constitutes a trade or business under § 162 — a true equipment leasing business produces SE income, while sporadic personal-asset rentals do not.
199A interaction
Even passive real estate rentals can be qualified trades or businesses for § 199A if they meet the § 162 trade-or-business standard or the Rev. Proc. 2019-38 safe harbor (250 hours, separate books, contemporaneous logs). The § 469 characterization and the § 199A characterization run on independent tracks.
