Internet and phone are some of the most commonly under-claimed deductions among freelancers. People worry they'll get in trouble for claiming personal use, so they claim nothing. The right answer is somewhere in the middle — and it usually adds up to $500-$1,500 a year in real deductions.
The Business Use Percentage Rule
You can deduct the percentage of your phone or internet bill that's used for business. The IRS wants a reasonable estimate — not a logbook of every minute. If your internet is 70% client work and 30% personal browsing, deduct 70% of the bill.
How to Calculate Your Business Percentage
- Hours-based: business hours / total connected hours per week
- Usage-based: data used for client work / total data
- Reasonable estimate: 'My freelance work fills 8 hours/day; personal use averages 2 hours/day → 80% business'
- Document the reasoning briefly in case you're audited
Phone Deduction — 50-80% Typical
Most freelancers can defensibly claim 50-80% of their phone bill as a business deduction. If your phone is your primary client communication tool — calls, texts, email, two-factor codes — 70% is a reasonable middle ground. Document briefly: 'Used primarily for client communication; estimate 70% business.'
100% business phone is hard to defend unless you have a separate personal phone. Stick to 50-80% on a single shared device.
Internet Deduction — Up to 100% if Primary Work Use
Home internet is more flexible. If your home is your primary place of business and internet is essential to your work, claiming 80-100% is defensible. If you have a small household and rarely stream personal media, you can claim up to 100%. Larger households with significant streaming/gaming should claim 50-70% to be safe.
Documenting Mixed Use
A short paragraph in your records is enough: 'Internet is essential to my freelance work (file uploads, video calls, research). I work 8+ hours daily. Personal use is minimal — checking email, occasional streaming. Estimated 80% business use.' Keep this with your tax records each year.
What Happens If You Are Audited
The IRS won't typically audit just over phone/internet percentages. If a broader audit happens, they want to see your reasoning — not minute-by-minute logs. A written percentage rationale, paired with bank statements showing the bill, is usually all that's needed.
Frequently Asked Questions
Should I get a separate business phone to claim 100%?
Only if it makes business sense — having two phones is a hassle. For most freelancers, claiming 50-80% of one phone is simpler and equally legitimate.
Does this apply to phone hardware too?
Yes. The cost of a phone (or its monthly device fee) is deductible at the same business-use percentage as the bill. A $1,200 phone used 70% for business → $840 deduction.
What about international roaming for client work abroad?
Fully deductible — it's a business expense incurred for business travel. Document the trip purpose (client meeting, conference, etc.).
Can I deduct cell tower / mobile hotspot equipment?
Yes, at the business-use percentage. A signal booster, mobile hotspot, or dedicated SIM for business use are all deductible.
