What the IRS Says
The IRS treats internet service as a utility expense. When used for both personal and business purposes, you must allocate the expense based on the percentage of business use. There is no specific IRS form line for internet alone — it falls under utilities (Line 25) or other expenses (Line 27).

- ☑Log or reasonable estimate of business vs. personal usage percentage
- ☑Business purpose documentation (client communications, cloud services, etc.)

Keeping Your Internet Service Receipts Straight
Knowing internet service qualifies is the easy part. Proving it eleven months later, from a receipt that faded in your glovebox, is where this deduction usually gets lost. Photograph the receipt when you get it and TaxTidy reads the vendor, the amount and the date off it in about three seconds, then files it under Schedule C, Line 25 — the same line you'll claim it on.
The documentation checklist above is the part most people only think about in April. Your Audit Readiness Score keeps it in front of you all year: it counts the expenses with no receipt attached, the ones still sitting uncategorized, and the ones missing a date or a vendor name. You see the gaps while you can still fix them.

Frequently Asked Questions
How do I calculate the business percentage of my internet?
Track your usage for a typical week, noting hours spent on business vs. personal use. If you work 8 hours a day and use the internet 2 hours personally, your business use is roughly 80%. The IRS accepts reasonable estimates.
Can I deduct internet if I work from home part-time?
Yes, but your business-use percentage should reflect part-time usage. If you work from home 3 days a week, your business percentage would be lower than a full-time remote worker.
Is a separate business internet line fully deductible?
Yes. If you have a dedicated internet connection used exclusively for business, 100% of that cost is deductible as a business expense.
