Section 179 for Rental Property: The Lodging Exclusion and Who Qualifies

By Tom, CPA · Updated October 27, 2026

Part of: Rental Property Taxes

TL;DR: Section 179 lets businesses expense qualifying property instead of depreciating it, with a 2026 limit of $2,560,000 phased out above $4,090,000. Most long-term residential landlords cannot use it: property used to furnish lodging is excluded, rentals held only for income do not qualify, and the deduction cannot exceed active business taxable income. Bonus depreciation usually does the job instead.

Educational only, not tax, legal, or investment advice. Examples are illustrations, not predictions. Rules and limits change; verify current figures and talk to a qualified professional about your situation.

Your tenant pays the mortgage; the IRS pays for the roof over 27.5 years. Someone on a podcast then says "just Section 179 it," and Lavish Larry tries to expense a new furnace for his duplex. Frugal Fran reads Publication 946 first. Fran wins.

Section 179 is an election to deduct the cost of qualifying property in the year it is placed in service, up to a dollar limit. It is powerful for operating businesses. For rental owners, it runs into three walls: the exclusion for property used to furnish lodging, the requirement that property be used in the active conduct of a trade or business, and a taxable income limit. This guide explains each wall, the narrow places where 179 still works for real estate investors, and why bonus depreciation, now 100% for property acquired after January 19, 2025, makes the question less urgent as of Oct 2026.

CPA Warning Label: Section 179 is the VIP line at the club. Most landlords are not on the list, and bonus depreciation lets them in through the side door anyway.

Section 179 basics

For tax years beginning in 2026, Rev. Proc. 2025-32 sets the Section 179 limit at $2,560,000, reduced dollar for dollar once qualifying property placed in service during the year exceeds $4,090,000. The cap for certain sport utility vehicles is $32,000. The 2027 figures are not yet announced.

Section 179 property generally means tangible section 1245 property (machinery, equipment, furniture and similar), off-the-shelf software, and, by election, qualified real property. Pub. 946 describes qualified real property as qualified improvement property and certain improvements to nonresidential real property placed in service after the building: roofs, heating, ventilation and air-conditioning property, fire protection and alarm systems, and security systems.

Key mechanics:

• You elect on Form 4562, asset by asset, and choose how much to expense.
• Property must be used more than 50% for business in the year placed in service.
• If business use later drops to 50% or less, part of the deduction is recaptured.
• The deduction is limited to business taxable income; the unused amount carries forward.

The residential rental exclusion

Pub. 946 lists property that does not qualify for Section 179, including "certain property used predominantly to furnish lodging or in connection with the furnishing of lodging (except as provided in section 50(b)(2))." This reaches the building and also furniture, appliances and other property used in a residential rental: the refrigerator in a long-term rental apartment is used in connection with furnishing lodging.

The section 50(b)(2) exception covers, among other things, property used by a hotel or motel where the predominant portion of accommodations is used by transients, and certain nonlodging commercial facilities available to the public. This is why short-term rental owners sometimes ask whether their property is "hotel-like" for 179 purposes. The answer depends on facts, and the exception is narrower than marketing posts suggest.

Also excluded: the residential building itself (it is section 1250 property), and qualified real property improvements are limited to nonresidential real property, so a new roof on a residential rental does not qualify.

Active trade or business requirement

Section 179 property must be acquired for use in the active conduct of a trade or business. Pub. 946 is explicit: property acquired only for the production of income, such as investment property and rental property where renting is not your trade or business, does not qualify.

Whether a rental activity is a trade or business depends on the regularity and continuity of your involvement. One condo you rent long-term with a property manager is often closer to an investment. A portfolio you actively run may be a business. This standard is different from the passive activity rules: you can be in a trade or business and still have passive losses under section 469 (Pub. 925), and material participation for 469 does not automatically answer the 179 question.

The safe harbor for rental real estate as a trade or business under the QBI rules (250 hours, separate books) is for section 199A purposes only, and does not by itself establish a trade or business for Section 179.

Where 179 can apply (STRs, furniture)

Illustration: Frugal Fran owns six long-term units and runs them as a business with no property manager. In 2026 she buys $6,000 of tools and a $1,800 laptop used 90% for the rental business, plus $12,000 of new refrigerators and ranges for units. The tools and the business share of the laptop ($1,620) may be 179-eligible if her activity is a trade or business and she has enough business income. The refrigerators and ranges are lodging property, not 179 property. She uses 100% bonus depreciation on the appliances instead, which gives the same first-year write-off without the 179 limits.

Taxable income limit

The 179 deduction cannot exceed the taxable income derived from the active conduct of any trade or business during the year. For individuals, wages count as active trade or business income for this purpose under the regulations (Pub. 946 explains that wages, salaries and tips are included). Any excess carries forward indefinitely, subject to the same limit later.

Contrast with bonus depreciation: bonus can create or increase a loss. That makes bonus more useful when a rental is already showing a tax loss. Example: if your business taxable income is $8,000 and you elect $15,000 of Section 179, you deduct $8,000 this year and carry $7,000 forward, while bonus would have deducted the full amount now. Whether that loss is usable is a separate passive loss question.

Why bonus usually wins for landlords

With 100% bonus depreciation permanent for property acquired after January 19, 2025 (Notice 2026-11), most of the reasons to fight for Section 179 on rental assets disappear:

• Bonus is available for residential rental components (appliances, carpet, land improvements) that 179 excludes.
• Bonus does not require a trade or business; it applies to depreciable rental property generally.
• Bonus has no dollar cap or taxable income limit.
• Bonus is automatic unless you elect out by class.

Section 179 still matters in a few cases: you want to expense some assets in a class but not others (179 is per asset; bonus elect-out is per class), qualified real property on nonresidential buildings (roofs and HVAC do not qualify for bonus as 39-year components), and states that conform to 179 but not bonus. Many states set their own 179 limits, so check the state instructions.

Recapture works similarly for both: depreciation on 1245 property is ordinary income when you sell. See real estate depreciation and the bonus depreciation guide.

Selling and home-sale overlap

If you later move into a former rental and sell it, the home sale exclusion does not shelter depreciation taken after May 6, 1997, including any 179 or bonus amounts; that gain is taxed. See the section 121 exclusion and partial exclusion for former rentals.
