Section 179 vs Bonus Depreciation for Rentals

If you're a landlord trying to figure out whether to use Section 179 or bonus depreciation on rental equipment, the honest answer is: the rental building itself doesn't qualify for either — it depreciates over 27.5 years, period. But appliances, equipment, and certain interior improvements often qualify for both, and choosing between them comes down to whether you have taxable income to absorb the deduction.

Okoniq Property Hub tracks each asset and its placed-in-service date so the numbers are ready when your CPA needs them. Here's the framework.

Why doesn't the building itself qualify?

Because Section 179 and bonus depreciation are designed for tangible personal property and certain interior improvements, not for real property (the building shell). Residential rental buildings depreciate on a required 27.5-year straight-line schedule — no shortcuts, no acceleration. This is one of those places where the tax code is not negotiable.

The land underneath doesn't depreciate at all. Only the building portion of your basis (typically 70–85% depending on the market) is depreciable.

What actually qualifies?

Items commonly eligible for Section 179 or bonus depreciation on a residential rental:

• Appliances (refrigerator, range, dishwasher, washer/dryer)
• Carpet and non-permanent flooring
• Certain furniture in furnished rentals
• Computers and equipment used for the rental business
• Vehicles used for rental-related travel (with limitations)
• Some interior improvements ("qualified improvement property" — post-2018 non-structural interior work in non-residential; residential is more restricted)

Detached improvements (a new HVAC system, a new roof) generally do NOT qualify for Section 179 on residential rental — they follow the 27.5-year schedule with the building. Consult a CPA on borderline items.

What's different about the two?

Section 179:

• Immediate deduction, up to the annual cap (over $1M in recent years — check current limits).
• Limited to your taxable income — you can't use Section 179 to create a loss. Excess carries forward.
• Historically has been restricted for property rented to others, though rules have loosened.

Bonus depreciation:

• Immediate deduction of a percentage of eligible property in year 1 (was 100%, now phasing down — 60% in 2024, 40% in 2025, 20% in 2026, 0% in 2027 under current law unless Congress extends).
• No taxable income limit — you can create a loss with bonus depreciation.
• Applies automatically unless you elect out; election is by class of property.

For most small landlords, bonus depreciation is the simpler default, especially given the phasedown. Section 179 becomes more attractive when you want to control the timing precisely and you have plenty of taxable income to absorb it.

Full rules are in IRS Publication 946 (How to Depreciate Property) and the Section 179 fact page.

Run both scenarios before choosing

Because Section 179 and bonus depreciation interact with passive-loss rules, at-risk rules, and Section 199A QBI deduction, it's worth running both scenarios with a CPA on any project over ~$5,000. Small purchases usually just get bonus depreciation by default.

Keep equipment purchases organized for depreciation

Each qualifying asset needs: date placed in service, cost basis, class life, and depreciation method. Okoniq Property Hub stores these alongside the receipt so the depreciation schedule assembles itself at year end.

Frequently asked questions

Can I use both Section 179 and bonus depreciation on the same asset?

Yes — take Section 179 first (up to income limit), then bonus depreciation on the remaining basis, then regular MACRS depreciation on whatever's left. The order matters.

What about the de minimis safe harbor?

Small items under $2,500 per invoice ($5,000 with audited financials) can be expensed as repairs under the de minimis safe harbor election — no depreciation needed. Often simpler than Section 179 or bonus for small stuff.

Does bonus depreciation apply to used equipment?

Yes — for property placed in service after 2017, used property qualifies as long as it's new to you. Older rules only allowed bonus on new property.

Not tax advice. Depreciation elections have long-tail consequences (recapture at sale, effects on QBI and passive losses). Confirm strategy with a licensed CPA. Okoniq Property Hub keeps every asset's paperwork organized so those conversations are quick. Get started free.
