The short answer
Yes. If you use your personal phone for business, you can deduct the business-use percentage of your monthly bill. Not 100% unless it's a dedicated business line. For most freelancers, 40–70% is defensible.
Where it goes on your return
Schedule C, Line 25 ("Utilities") or Line 48 ("Other expenses" labeled as "Cell phone"). Software typically asks directly: "How much did you pay for business use of your personal phone?"
What percentage can I claim?
| Your situation | Defensible % |
|---|---|
| Dedicated business phone (separate device + number) | 100% |
| Primary phone, heavy client calls/texts | 60–80% |
| Typical freelancer, some business use | 40–60% |
| Light business use (occasional calls) | 20–30% |
The dollar math
$85/month plan × 12 × 50% business use = $510/year deduction.
At a 22% federal bracket + 15.3% SE tax, that's about $190 in refund annually. Over a decade, $1,900. Worth claiming.
How to document it (in case of audit)
You don't need a perfect log, but you do need a reasonable basis. Three options:
- One-week sample. For one representative week, track business vs personal minutes/texts/data. Use the ratio. Save a note.
- App-based tracking. Apps like TimelyApp or your phone's built-in screen time can show business app usage (Slack, Gmail, Zoom) vs personal (Instagram, games).
- Reasonable estimate with explanation. Note it as: "Primary phone also used for business. Business use estimated at 50% based on client communication volume and app usage."
What you can't claim
- The phone itself as a full expense if it's your only phone and you use it personally. You'd claim the business-use percentage of depreciation — more complicated than most $800 phones are worth.
- Your family's phones on the same plan. Only your line.
- 100% of a single-phone household. The IRS will disallow it if it's clearly also your personal phone.
The "dedicated business line" alternative
Want a cleaner deduction? Get a second line (Google Voice, Grasshopper, OpenPhone — $10–$30/mo) dedicated to business. Deduct 100%. Cleaner at audit, and you can stop giving out your personal number to clients.
