If you work from home, you can write off your internet bill only if you’re self-employed and the space you work from qualifies as a home office. W-2 employees cannot take this deduction on their federal return, no matter how many hours a day they’re online for work. Independent contractors, freelancers, and sole proprietors deduct the business-use portion on Schedule C.
Employees Cannot Deduct Home Internet Federally
If you receive a W-2, none of your home internet bill is deductible on your federal return. The Tax Cuts and Jobs Act suspended all miscellaneous itemized deductions, the category that had covered unreimbursed employee expenses, for tax years 2018 through 2025. The One Big Beautiful Bill Act, signed on July 4, 2025, removed the end date entirely, making the suspension permanent for tax years beginning after December 31, 2017.1Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions
A handful of states still allow unreimbursed employee expenses on the state return. That’s worth checking with your state tax authority, but the federal door is closed.
Reimbursement Is the Employee’s Only Route
The way an employee actually recovers internet costs is through the employer. To keep the payment tax-free, the employer has to use what the IRS calls an accountable plan: you document your actual expense, submit it, and return any amount that exceeds what you spent. Reimbursements handled this way stay off your W-2.2eCFR. 26 CFR 1.62-2 – Reimbursements and Other Expense Allowance Arrangements
A flat monthly stipend with no receipts required is the opposite arrangement. It gets added to your W-2 as ordinary wages and taxed. You cannot then deduct the expense to offset it.3Internal Revenue Service. Revenue Ruling 2003-106
Self-Employed: You Need a Qualifying Home Office
Sole proprietors, freelancers, independent contractors, and gig workers report on Schedule C, and internet service is an ordinary and necessary business expense.4Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses The business-use portion is deductible, but only if you meet the home office rules.
The core test has two parts. The space must be used exclusively for business, and it must be used regularly. A desk tucked into a guest room that still hosts guests fails the exclusive-use test. A converted spare room used only as your office passes it.
The space also has to be your principal place of business. The IRS reads that broadly enough to include an office used mainly for administrative and management work, as long as you don’t have another fixed location where you handle a substantial amount of that same work.5Office of the Law Revision Counsel. 26 USC 280A – Disallowance of Certain Expenses in Connection With Business Use of Home
Two other paths qualify. A space where you regularly meet clients or customers counts, even if you do most of your work elsewhere. And a separate structure on your property, such as a detached garage you’ve converted into a studio, qualifies as long as you use it in connection with your business.
How to Calculate the Deductible Portion
Once you qualify, you pick one of two methods.
Actual Expense Method Using Form 8829
On Form 8829, you figure a business percentage of your home and apply it to indirect expenses like internet.6Internal Revenue Service. Form 8829 – Expenses for Business Use of Your Home The usual approach is square footage: a 200-square-foot office in a 2,000-square-foot home gives you 10%, so a $100 monthly internet bill produces a $10 monthly deduction.
Square footage works cleanly for things tied to physical space. Internet is a little different, because you might use it forty hours a week for work and much less for personal browsing. Some taxpayers use a time-based allocation instead, applying the ratio of business hours to total usage hours. The IRS does not prescribe a formula for internet proration. Whatever method you pick needs to be reasonable, applied consistently, and backed by records you can produce if asked.
Simplified Method
The simplified method skips Form 8829. You deduct $5 per square foot of office space, up to 300 square feet, for a maximum of $1,500 per year.7Internal Revenue Service. Simplified Option for Home Office Deduction That flat figure covers everything home-related, including internet. You cannot add a separate internet deduction on top. If your home expenses are modest, the simplicity is worth it. If they aren’t, running Form 8829 almost always beats it.
The Gross Income Cap
Your home office deduction, internet included, cannot exceed the gross income from the business that uses the office. It can’t create or deepen a loss. If you earned $5,000 from freelancing and your home office expenses total $6,200, you deduct $5,000 this year and carry the $1,200 forward. The carryforward has no expiration date.5Office of the Law Revision Counsel. 26 USC 280A – Disallowance of Certain Expenses in Connection With Business Use of Home8Internal Revenue Service. Publication 587 – Business Use of Your Home
Routers, Modems, and Other Hardware
The monthly service bill isn’t the whole picture. Routers, modems, mesh systems, and similar equipment bought for business use are deductible. Items costing $2,500 or less can be fully written off in the year you buy them under the de minimis safe harbor election, so most home networking gear comes off in one shot rather than through depreciation.
Mixed-use equipment follows the same proration logic as the service itself. A $200 router used 60% for business gives you a $120 deduction. Keep the receipt and note the business-use percentage.
What to Keep in Your Records
The IRS requires records sufficient to support any deduction you claim.9Office of the Law Revision Counsel. 26 USC 6001 – Notice or Regulations Requiring Records, Statements, and Special Returns For internet, that means three things:
- Every monthly bill for the tax year, showing provider, amount, and billing period.
- Your business-use calculation. For square footage, a floor plan or diagram with the office dimensions and total home size. For time-based allocation, a contemporaneous log of business usage hours. A spreadsheet or calendar kept up weekly is far more credible than a lump estimate reconstructed at tax time.
- Receipts for any routers, modems, or other hardware you deducted, with the business-use percentage noted.
Hold the documentation for at least three years from the date you filed the return.
