Can You Write Off Your Home Internet Bill? A Guide for Remote Freelancers

Introduction

Yes, you can write off part (or all) of your home internet bill as a business expense if you use it for freelance work. The IRS allows self-employed workers to deduct ordinary and necessary business expenses on Schedule C, and internet service qualifies—as long as you can demonstrate a clear business purpose and keep good records. This guide walks you through how much you can deduct, how to calculate your business-use percentage, and what documentation you need to stay audit-proof.

Key Takeaways:

• You can deduct the business-use percentage of your home internet on Schedule C
• If you use internet 80% for work and 20% personal, you deduct 80% of the monthly bill
• You must keep records showing the business purpose and usage split
• Internet expenses are reported on Schedule C, Line 25 (Utilities) or Line 27a (Other expenses)
• You don't need a dedicated business line—the IRS allows mixed-use deductions based on actual usage

How much of your internet bill can you deduct?

You can deduct the percentage of your internet service that you use exclusively or primarily for business. The IRS requires you to allocate mixed-use expenses between personal and business use based on actual usage. If your internet connection is used 100% for business (rare for home-based freelancers), you can deduct 100% of the cost. More commonly, you'll split the cost.

To calculate your deduction, track how many hours per week you use the internet for business versus personal activities. For example:

• You work 40 hours per week online for client projects, invoicing, communication, and research
• You use the internet 10 hours per week for personal browsing, streaming, and social media
• Total weekly usage: 50 hours
• Business percentage: 40 ÷ 50 = 80%

If your monthly internet bill is $75, you can deduct $60 per month ($75 × 80% = $60), or $720 per year.

The IRS does not require a separate business internet line. You can deduct a portion of your home internet as long as you have a reasonable, documented basis for your allocation.

What counts as business use of internet?

Business use includes any activity directly related to earning freelance income. According to IRS Publication 535 (Business Expenses), ordinary and necessary expenses are deductible if they are common and accepted in your trade and helpful to your business.

Examples of deductible internet activities:

• Video calls with clients (Zoom, Teams, Google Meet)
• Sending and receiving work emails
• Uploading and downloading project files
• Research and professional development
• Managing invoices and accounting software
• Marketing your services (website, social media for business, portfolio updates)
• Online courses or webinars related to your field
• Cloud storage for work files (Dropbox, Google Drive)

Not deductible as business use:

• Streaming Netflix, Hulu, or YouTube for entertainment
• Personal social media scrolling (unless you're a social media manager working on client accounts)
• Online shopping or personal banking
• Gaming or other personal hobbies

Keep contemporaneous logs or time-tracking data to support your business-use percentage, especially if it's above 75%.

How to report your internet deduction on Schedule C

Report your deductible internet expenses on Schedule C (Form 1040), Profit or Loss from Business. You have two options:

1. Line 25 (Utilities): Many freelancers report internet here alongside phone and other utilities
2. Line 27a (Other expenses): If you prefer to break out internet separately, list "Internet service" in Part V and enter the amount

Both approaches are acceptable. Choose the one that keeps your records clearest.

Step-by-step process

1. Add up your total annual internet costs (12 months × monthly bill)
2. Multiply by your business-use percentage
3. Enter the result on Schedule C, Line 25 or Line 27a
4. Keep a one-page memo in your tax files explaining how you calculated the percentage
5. Save copies of your internet bills for at least three years

Example:

You paid $80/month for high-speed internet in 2026, totaling $960 for the year. You documented that 75% of your usage was for freelance graphic design work. Your deduction: $960 × 75% = $720. You report $720 on Schedule C, reducing your taxable self-employment income and saving approximately $110 in self-employment tax (at the 15.3% rate) and $173 in income tax (if you're in the 24% bracket)—a total tax savings of around $283.

Do you need the home office deduction to write off internet?

No, you do not need to claim the home office deduction (Form 8829 or the simplified method) to deduct internet expenses. These are separate deductions. Internet is considered a business utility or expense on its own, and you can claim it even if you work from a coffee shop, coworking space, or don't have a dedicated home office.

That said, if you do claim the home office deduction, you might allocate internet in one of two ways:

• Direct expense: Deduct the business-use percentage of internet on Schedule C, Line 25 (as described above)
• Indirect home office expense: Include the full internet bill as part of your home expenses on Form 8829, where it's allocated by the square footage of your office

Most freelancers find it simpler to deduct internet directly on Schedule C rather than bundling it into Form 8829.

What records do you need to keep?

The IRS may ask you to substantiate any business expense deduction. For internet, keep:

• Monthly bills or annual statements from your internet service provider
• A written log or calculation showing how you determined your business-use percentage (e.g., a spreadsheet tracking weekly hours or a memo drafted at year-end)
• Calendar or time-tracking data from tools like Toggl, Clockify, or your scheduling app that show client work hours

You don't need to log every minute of every day, but you should be able to explain your methodology if audited. A reasonable, consistent approach (like "I work 40 hours/week and my household uses the internet 10 hours/week for personal use") is usually sufficient.

Store these records for at least three years from the date you file your return (or two years from when you paid the tax, whichever is later).

Internet deduction vs. cell phone deduction: what's the difference?

Both internet and cell phone expenses are deductible using similar rules: you allocate between business and personal use and deduct the business portion. However, there are a few practical differences:

If you have a second internet connection used 100% for business (e.g., a fiber line in a detached studio), you can deduct the full cost without allocation.

Common mistakes to avoid

Deducting 100% when you use it personally

The IRS will disallow deductions that ignore personal use. If you stream TV shows, browse social media, or shop online using the same connection, you cannot claim 100%. Be honest and conservative in your allocation.

Not documenting your calculation

Writing "100% business use" on Schedule C without backup is a red flag. Even a one-paragraph memo explaining your hours and usage split can protect you in an audit.

Double-dipping with the home office deduction

If you include internet as an indirect expense on Form 8829, don't also deduct it on Line 25 of Schedule C. Choose one method and stick with it.

Forgetting to track changes in usage

If your work pattern changes mid-year (e.g., you took on more clients or switched to in-person work), adjust your business-use percentage accordingly. Calculate it on a monthly or quarterly basis if your usage fluctuates significantly.

Deducting installation or equipment separately

One-time setup fees, modem purchases, or router upgrades may be deductible, but they're separate from your recurring monthly service fee. Small equipment purchases under $2,500 can be expensed in the year of purchase under the de minimis safe harbor election. Larger items may need to be depreciated.

Can you deduct upgraded or premium internet plans?

Yes, as long as the upgrade is necessary for your business. If you need faster speeds to upload large video files, host webinars, or run cloud-based design software, upgrading from a basic plan to a higher-speed tier is justifiable. Deduct the business-use percentage of the premium plan's cost.

However, if you upgrade to a plan with 1 Gbps speed primarily to support 4K streaming for personal entertainment, the IRS might question the business necessity of the extra cost. Stick to what you genuinely need for work, and document the business reason (e.g., "Upgraded to 500 Mbps to support client video calls and large file transfers").

What if you work remotely for an employer part-time and freelance part-time?

If you receive a W-2 from an employer and have freelance income reported on Form 1099-NEC, you can only deduct the internet expense attributable to your self-employment work on Schedule C. Employees generally cannot deduct home office or internet expenses for W-2 work under current tax law (the Tax Cuts and Jobs Act suspended unreimbursed employee expense deductions through 2025, and this suspension continues into 2026).

Allocate your internet usage three ways:

1. W-2 remote work hours (not deductible)
2. Freelance/1099 work hours (deductible on Schedule C)
3. Personal use (not deductible)

For example, if you work 20 hours/week as a W-2 remote employee, 15 hours/week on freelance projects, and 5 hours/week personal use, your freelance business-use percentage is 15 ÷ 40 = 37.5%. Deduct 37.5% of your internet bill on Schedule C.

Conclusion

Deducting your home internet bill is one of the simplest and most valuable write-offs for remote freelancers. Calculate your business-use percentage honestly, keep a short written explanation and copies of your bills, and report the deduction on Schedule C, Line 25 or Line 27a. If your situation is complex—like mixed W-2 and 1099 income, or you're unsure how to allocate usage—consult a CPA to maximize your deduction while staying audit-proof.
