Why It Matters
You're buying a furnished short-term rental and spending $48,000 on beds, sofas, a flat-screen in every room, and kitchen appliances. Without §179, you'd recover that over five to seven years in small annual chunks. With the election, you deduct the full $48,000 this year. That's the core appeal. The 2024 limit is $1,160,000, so most individual investors never hit the ceiling. The catch is that §179 can't exceed your taxable income from active business — it can't create a loss. If you need a loss, bonus depreciation is the tool. If you want to dial in an exact deduction amount to manage your tax bracket, §179 gives you that precision.
At a Glance
- What it is: An IRS election to fully deduct qualifying personal property in the year placed in service
- 2024 limit: $1,160,000 (phases out dollar-for-dollar above $2,890,000 of qualifying purchases)
- Income cap: Cannot exceed taxable income from active business — no loss creation allowed
- Best fit: STR investors expensing furnishings; operators wanting bracket-precise deductions
- Key risk: Recapture as ordinary income if §179 property is sold before end of recovery period
Max Deduction = Min($1,160,000, Qualifying Cost) − Max(0, Qualifying Cost − $2,890,000)
How It Works
The election itself. Section 179 is a choice you make at tax time on Form 4562. You're telling the IRS you want to treat the cost of qualifying property as a current-year expense rather than a capitalized asset. That's the mechanical flip: instead of an asset sitting on your depreciation schedule shrinking by a few hundred dollars a year, the cost hits your tax return this year in full. You can elect §179 for some qualifying items and not others — it's not all-or-nothing.
What qualifies for real estate investors. The building structure never qualifies — that's 27.5-year accelerated depreciation territory. What does qualify is tangible personal property: refrigerators, washers, dryers, dishwashers, window treatments, carpeting, furniture, and electronics. For STR owners, that's essentially the entire furnishing package. A cost segregation specialist identifies which components clear the personal-property threshold — useful when the line between fixture and personal property gets blurry. Qualified Improvement Property (interior work on nonresidential buildings) technically qualifies for §179, but bonus depreciation usually wins there because it has no income limit.
The income cap and carry-forward. This is where §179 differs sharply from bonus depreciation. Your §179 deduction can't exceed your net income from active trades or businesses. Rental income is passive, so if your only income is passive rental income, §179 won't help unless you qualify as a real estate professional. Unused §179 carries forward indefinitely — no expiration — but you lose the time value of money waiting for future income to absorb it.
Real-World Example
David converts a beach house in Destin, Florida to a short-term rental in October 2024. He spends $43,600 outfitting it: $18,400 furniture, $9,200 appliances, $7,800 electronics, $8,200 linens and decor. His W-2 income leaves him with $84,000 of taxable income after deductions.
He elects §179 on all $43,600 — well under both the $1,160,000 limit and his $84,000 income ceiling. The deduction saves him roughly $10,032 in federal taxes. Without the election, normal depreciation would have returned about $7,500 in Year 1. Section 179 accelerated more than $36,000 of future deductions into the acquisition year.
He also flags the recapture risk: sell in two years and those fully expensed items trigger §1245 recapture as ordinary income.
Pros & Cons
- Full deduction in Year 1 rather than small annual amounts over five to seven years
- Precise control — you elect exactly how much to expense, letting you target a specific tax bracket
- No dollar limit for most individual investors ($1,160,000 ceiling is very high)
- Unused amounts carry forward indefinitely if you hit the income cap
- STR furnishing packages (often $30,000–$80,000) can be expensed entirely in the acquisition year
- Cannot create a loss — §179 is capped at your active taxable income
- Passive-activity investors without real estate professional status get limited benefit
- Recapture risk: §1245 recapture as ordinary income if you sell before the end of the recovery period
- Less flexible than bonus depreciation for loss-generation strategies
- Phase-out reduces available deduction dollar-for-dollar above $2,890,000 in qualifying purchases (affects large commercial operators more than individual landlords)
Watch Out
Recapture on sale. If you expense $43,000 in furnishings under §179 and sell the property two years later, that $43,000 isn't gone — it comes back as §1245 recapture taxed at ordinary income rates. Factor recapture into your exit-year tax projection, not just your acquisition-year tax plan. Your CPA should model the recapture impact before you elect §179 on items you expect to dispose of soon.
The passive-activity trap. Rental income is passive. Most investors can't use §179 deductions from passive rentals to offset their W-2 or active business income. If your tax situation is purely passive rental activity without real estate professional qualification, the de-minimis safe harbor under the de-minimis safe harbor rules or regular depreciation may be more practical than an election that carries forward without reducing this year's tax bill.
Coordination with bonus depreciation. You can use both §179 and bonus depreciation in the same year, but the order matters: §179 applies first, then bonus depreciation applies to remaining basis. Don't assume using one means you can't use the other. In practice, many STR investors elect §179 for a specific amount to hit a target deduction, then let bonus depreciation pick up the rest.
Phase-out on large purchases. For investors placing more than $2,890,000 of qualifying property in service in a single year — think large commercial operators or syndicators outfitting multiple properties — the §179 benefit phases out dollar-for-dollar. At $4,050,000 of qualifying property, §179 disappears entirely. Individual investors rarely hit this, but it's worth knowing if you're scaling.
The Takeaway
Section 179 expensing is one of the most practical tools in a real estate investor's tax kit — especially if you're furnishing short-term rentals. The $1,160,000 limit means most individual investors can expense every qualifying item they buy in a year without hitting the ceiling. The key constraint is the income cap: you can't use §179 to generate a loss. If that's your goal, coordinate with bonus depreciation and talk to a cost segregation specialist about which items qualify. Done right, §179 can move tens of thousands of dollars of future depreciation into Year 1, changing your effective tax rate on the acquisition year entirely.
