Bonus Depreciation and Nashville STRs in 2026: What Actually Qualifies?

Bonus depreciation for Nashville short-term rental investors can materially affect a property's tax analysis. But it is not a universal deduction of the home's entire purchase price, and it does not turn a weak investment into a good one. Tax treatment depends on the taxpayer, qualified assets, acquisition and placed-in-service dates, business use, and passive-activity rules.

The questions to ask a CPA are more useful than a blanket promise about a giant first-year write-off.

What changed for eligible property after January 19, 2025?

The IRS announced guidance in January 2026 addressing the restoration of a permanent 100% additional first-year depreciation deduction for certain qualified property acquired after January 19, 2025. The rule has eligibility requirements. The term qualified property is doing substantial work here—it does not mean the entire value of a residential building or the land beneath it.

Review the IRS's January 2026 guidance announcement and applicable current regulations with a tax professional rather than relying on a social-media calculation.

Building, land, furnishings and shorter-life assets are different

Land is not depreciated. The building itself generally follows an applicable real-property recovery period. Furniture, appliances, equipment and certain other components may have shorter recovery periods, depending on their classification and use.

A cost segregation study attempts to identify and document properly classified assets that may be depreciated differently from the building. It requires technical support; reclassifying components without a defensible basis creates tax risk. The IRS cost segregation audit guide describes what the agency examines.

There is no legitimate one-size-fits-all percentage of purchase price that every Airbnb buyer can deduct immediately.

Placed in service is not the same as closing

Acquisition date, completion of furnishing or renovation, and the date an asset is placed in service may affect the applicable deduction. A buyer who closes in December but cannot make the rental ready for its intended use until a later tax year should not assume every anticipated deduction belongs on the closing-year return.

If your investment plan depends on a tax treatment in a particular year, ask the CPA to review the actual transaction calendar and documentation before you set a closing deadline.

The passive-loss question is separate

Short stays do not automatically mean a taxpayer can deduct all losses against salary or other income. IRS passive-activity rules include exceptions to the definition of rental activities—for example, when average customer use is seven days or less—but the owner's material participation, grouping, other activity rules and personal circumstances still need review. Read IRS Publication 925.

An investor who hires a full-service manager and spends little time operating the rental should not assume the same tax treatment as an owner who materially participates. Nor should a short-term-rental label by itself establish eligibility for any particular tax result.

Work backward from the actual deal economics

Tax planning belongs after an independent operating analysis. Consider an acquisition with weak after-debt cash flow: a potential accelerated deduction might improve the owner's overall tax position, but it does not pay monthly expenses, change the permit situation, or eliminate refinancing risk.

Evaluate purchase price, expected revenue, management costs, reserves and financing first. Our Nashville STR cash-flow example provides a transparent operating framework.

A useful conversation with your CPA

Bring the purchase agreement, allocation of land/building/furnishings if supportable, closing date, anticipated placed-in-service date, proposed legal structure, personal-use plans, financing information, and a realistic description of who will operate the rental and how.

Ask whether a study is warranted, which property classes actually qualify, how depreciation recapture and future sale economics might work, and how passive-activity limitations affect your return.
