How do I allocate WiFi costs between personal and business use?

The most common allocation method for a mixed-use internet connection is by rental days vs. total days. If your property is rented 200 days and used personally 30 days (230 total), the business-use percentage is 200/230 = 87%. Alternatively, if the STR property has its own separate internet account that you don't personally use, 100% is deductible.

Are WiFi routers and extenders deductible?

Yes. WiFi routers, range extenders, mesh network systems (Eero, Orbi, Google Nest WiFi), and ethernet switches installed at an STR property are deductible as business equipment. Under the de minimis safe harbor, devices costing under $2,500 can be expensed immediately. Section 179 also applies.

Where does internet expense go on Schedule C?

Internet service for your STR goes on Schedule C Line 27a (Other expenses), labeled as 'Internet / utilities.' Some CPAs place it on Line 25 (Utilities) if you include it with other utility expenses. Either is acceptable — be consistent year to year.

Is WiFi a Deductible Expense for Airbnb?

Q: Can I deduct WiFi for my Airbnb?

Yes. Internet service provided at an STR property is fully deductible under IRC §162(a) as an ordinary and necessary business expense. If the internet connection is dedicated exclusively to the rental property, 100% of the cost is deductible. If shared with personal use, you must allocate the deduction based on business vs. personal use.

Yes — internet service provided at an Airbnb or STR property is fully deductible under IRC §162(a). If the internet connection is dedicated exclusively to the rental (a separate account in the property's name), 100% of the monthly bill is deductible. If the connection is shared with personal use, you must allocate the deduction using a reasonable method based on rental days versus personal use days.

Dedicated STR Internet Connection: 100% Deductible

The simplest and most tax-favorable scenario is a dedicated internet account set up specifically for the rental property, separate from any personal internet connection you use at home. When guests are the only users of this connection and you have no personal use, the full monthly bill is deductible with no allocation required.

This is the setup most commonly used by hosts with dedicated STR properties (properties they never personally occupy). The internet account is typically in the property's name or your business name, and the service address is the rental property — making the business purpose unambiguous.

Dedicated STR Internet Account

Schedule C, Line 27a

100% deductible. No allocation required. Report full monthly bill on Line 27a labeled as "Internet / WiFi — rental property."

Example: $80/month dedicated fiber internet at rental property = $960/year, fully deductible on Schedule C Line 27a.

Shared Personal and STR Internet: Must Allocate

Many STR hosts — particularly those who rent out a room in their primary residence, or who use a vacation home for both rentals and personal stays — share a single internet connection between rental use and personal use. In this case, you must allocate the internet expense between business and personal use.

Allocation Method 1: Rental Days vs. Total Use Days

Day-Based Allocation

Most Common Method

Divide the number of days the property was rented by the total number of days it was occupied (rental + personal). Apply that percentage to your annual internet bill.

Example: Rented 180 days, personal use 45 days (225 total). Business use = 180/225 = 80%. Annual internet bill = $1,080. Deductible amount = $864.

Consistent Documentation

Document your allocation method in writing and apply it consistently year to year. The IRS does not prescribe a specific method, but it must be reasonable and consistently applied. Keep your rental calendar alongside your tax records so your allocation can be verified.

Business-Grade Internet for STRs

Some STR hosts install business-grade internet (gigabit fiber, dedicated business accounts) to provide superior connectivity for guests who work remotely. Business internet plans ($80–$200/month) are fully deductible as a business expense when the account is dedicated to the STR. The higher cost compared to a consumer plan is not a problem — business-grade service is clearly an ordinary and necessary expense for a property that markets to digital nomads or remote workers.

WiFi Equipment: Routers, Extenders, Mesh Systems

In addition to the monthly internet bill, the equipment you install to provide WiFi coverage is also deductible. This includes:

WiFi routers: Asus, TP-Link, Netgear (typically $50–$300)
Mesh WiFi systems: Eero, Orbi, Google Nest WiFi, Ubiquiti (typically $150–$500)
WiFi extenders and repeaters: For coverage in outbuildings, garages, or large properties
Ethernet switches and cabling: For wired connections in the property
Outdoor weatherproof access points: For pool areas, patios, and outdoor spaces

Equipment costing under $2,500 qualifies for the de minimis safe harbor and can be expensed immediately. Larger systems can be expensed under Section 179 or depreciated as 5-year MACRS property.

The Business Case for Mesh WiFi

"Strong WiFi" is consistently one of the top-rated amenities in STR guest reviews. Spending $350 on an Eero Pro mesh system is a legitimate business investment — and at a 22% tax rate, the after-tax cost is only $273. If it earns you a single extra booking ($150 nightly) per year, it pays for itself many times over.

What About Hotspot Devices?

If you use a mobile hotspot device as a backup or primary internet source for your STR (common in rural areas), the device and associated data plan are deductible. A dedicated hotspot used exclusively for the rental is 100% deductible. A personal hotspot you also share with the STR is subject to the same allocation rules as any other mixed-use internet expense.
