Can I Deduct Smart Home Devices for My STR?
No credit card required
Yes — smart home devices installed at your short-term rental are fully deductible as business equipment under IRC §162(a) and IRC §179. Smart locks, Ring cameras, noise monitors (NoiseAware, Minut), smart thermostats, and smart TVs all qualify. Devices under $2,500 can typically be expensed immediately under the de minimis safe harbor; monthly subscription fees for connected services are deductible separately as ongoing operating expenses.
The IRS Framework: Why Smart Devices Are Deductible
Under IRC §162(a), all ordinary and necessary business expenses are deductible. Smart home devices for an STR are ordinary (virtually every professionally managed STR uses them) and necessary (they directly facilitate operations — keyless entry, property security, guest communication, energy management). They qualify as business equipment, which is 5-year MACRS property for depreciation purposes.
Better yet: under the de minimis safe harbor (Reg. §1.263(a)-1(f)), taxpayers with an applicable financial statement can expense items up to $5,000 per item; without one, the threshold is $2,500 per item or invoice. Most smart home devices fall well under this threshold, meaning you can deduct the full purchase price immediately without any depreciation schedule.
A smart lock at $250, a Ring camera at $200, a NoiseAware sensor at $150, and a smart thermostat at $180 total $780. All four can be expensed in full in the year of purchase — no depreciation schedule required. If you also use Section 179, virtually all smart home tech qualifies for full first-year expensing regardless of cost.
Device-by-Device Breakdown
Smart Locks
Schedule C, Line 27a or Form 4562Smart locks (August, Schlage Encode, Yale, Igloohome, Salto) eliminate the need for key handoffs and allow remote access management. The hardware cost is deductible; under the de minimis safe harbor, most locks ($150–$350) are expensed immediately. Any associated app subscription for remote management is a separate deductible software expense.
Security Cameras & Video Doorbells
Schedule C, Line 27a or Form 4562Ring, Nest, Arlo, Wyze, and similar cameras used for property security are deductible. The hardware is expensed immediately (under $2,500) or via Section 179. Cloud storage subscriptions (Ring Protect, Google Nest Aware) are fully deductible as monthly operating expenses.
Noise Monitors
Schedule C, Line 27aNoise monitoring devices (NoiseAware, Minut, Party Squasher) help hosts detect unauthorized parties without invading guest privacy. These are increasingly required by HOAs and local STR ordinances. Hardware is deductible; monthly monitoring subscriptions ($10–$30/month) are deductible operating expenses.
Smart Thermostats
Schedule C, Line 27a or Form 4562Smart thermostats (Ecobee, Nest, Honeywell) allow remote temperature management between guests, reducing energy costs. Fully deductible as business equipment. Ecobee and Nest devices ($150–$250) qualify for immediate expensing under the de minimis safe harbor.
Smart TVs and Streaming Devices
Schedule C, Line 27a or Form 4562Smart TVs purchased for guest use are deductible. Larger TVs ($500+) may need to be depreciated or claimed under Section 179 rather than the de minimis safe harbor. Streaming sticks (Roku, Fire Stick, Apple TV) at under $100 are expensed immediately. Monthly streaming service subscriptions are generally not deductible unless they are specifically for guests and not personally used by the host.
Monthly Subscription Fees: Deducted Separately
The hardware (one-time purchase) and the subscription (recurring) are treated differently for tax purposes but both are fully deductible. Monthly fees go on Schedule C Line 27a (Other expenses) and should be labeled as "Technology subscriptions" or "STR smart home subscriptions."
| Device / Service | Typical Hardware Cost | Monthly Subscription |
|---|---|---|
| Smart Lock | $150–$350 | $0–$10 |
| Ring / Security Camera | $100–$500 | $3–$20 |
| NoiseAware / Minut | $100–$200 | $10–$30 |
| Smart Thermostat | $150–$250 | $0 |
Keep all smart device receipts organized by property. If you manage multiple STRs, track which devices are at which property. This is critical for depreciation schedules and for proving business purpose if audited. Receipts from Amazon, Best Buy, or the manufacturer's website are all acceptable documentation.
What About Smart Devices at a Mixed-Use Property?
If the smart devices are at a property you also use personally, you must allocate the deduction. A smart lock or thermostat at a vacation home you use 60 days personally and rent 180 days would yield a 75% business-use deduction. Devices at a dedicated STR with zero personal use are 100% deductible with no allocation required.
