Running a home business means every dollar counts. The right smart home devices can boost your productivity — and some may qualify as tax-deductible business expenses. We break down the best smart hubs, displays, assistants, and lighting bridges for your home office, with a plain-language guide to IRS rules on deducting them.
If you run a business from home, your smart home setup can do double duty: make you more productive during the workday, and potentially lower your tax bill at the end of the year. The key is understanding which devices qualify as deductible business expenses and how to document them properly.
Here's our guide to the best smart home devices for home businesses — plus what the IRS actually says about writing them off.
A well-chosen smart hub or voice assistant saves you time on the small stuff: checking your calendar, setting timers, controlling lights during video calls, or adjusting the thermostat without leaving your desk. Over a year, those seconds add up to real focus time.
But there's another angle. If you use a device exclusively for your home office, the IRS may let you deduct it as a business expense. That's where things get interesting — and where you need to be careful.
The IRS lets you deduct expenses for the business use of your home under two main tests, outlined in Publication 5872:
If you qualify, you can deduct the business portion of expenses like utilities, rent, mortgage interest, and real estate taxes1. And yes, that can include smart home devices — if they're used for your business.
This is where smart home devices get tricky. The IRS distinguishes between:
Our take: If you want to maximize deductions cleanly, keep a dedicated smart device in your office and use it only for business. That makes it a direct expense, no percentage calculations needed.
The Nest Hub is our top pick because it does exactly what a home office assistant should: show your calendar at a glance, set timers and reminders by voice, control office lights and thermostats, and play white noise or focus music — all without a camera, which is a nice privacy bonus for a workspace.
Its 7-inch display is compact enough to sit beside your monitor without cluttering your desk. The Sunrise Alarm feature can gently wake you into your workday, and the digital photo frame mode keeps the space feeling human when you're not actively using it.
Best for: Dedicated office use where you want a screen but don't need a camera.
If your home business involves regular video calls, the Echo Show 8 is worth a look. Its 8-inch HD display and built-in camera make it a viable second screen for Zoom or Google Meet, and the adaptive color feature adjusts the screen to match your room's lighting — useful if your office gets afternoon sun.
You can manage your calendar, check email snippets, control smart office devices, and even use it as a digital sticky note board with Alexa Shopping Lists and Reminders. The 13 MP camera is surprisingly decent for a smart display.
Best for: Home business owners who want video call capability in a dedicated office device.
Sometimes you don't need a screen — you just need to talk to your office. The spherical Echo (4th Gen) is a solid voice assistant for hands-free productivity: set cooking timers for lunch, ask for weather before your commute (even if that commute is down the hall), control office lights and plugs, and add items to your shopping list without breaking focus.
Its Zigbee smart home hub is built in, meaning it can directly control compatible smart lights, locks, and sensors without needing a separate bridge. That makes it a cost-effective hub for a small office setup.
Best for: A dedicated office voice assistant that also acts as a smart home hub.
Lighting quality directly affects productivity and eye strain. The Lutron Caseta Smart Bridge lets you control your office lights from your phone, set schedules, and integrate with Alexa or Google Assistant for voice control.
The killer feature for home businesses: you can set "scenes" for different work modes. A bright, cool scene for deep-focus work. A warmer, dimmer scene for video calls (softer light is more flattering on camera). And an "away" scene that turns everything off when you leave — saving energy and qualifying as a utility cost reduction.
The bridge connects to the Pico remote, which you can mount on your desk or wall for a physical switch that doesn't require pulling out your phone.
Best for: Home office lighting optimization with scheduling and voice control.
If you plan to deduct any of these devices, here's what tax professionals recommend:
Smart home devices can genuinely improve your home office workflow — and if you're careful about the IRS rules, they can also reduce your taxable income. Pick a device that fits your actual work needs, keep it in your dedicated office space, and document your usage. That's the smart play.
