If you use your smartphone for work—whether you’re a freelancer, gig worker, remote employee, or small business owner—the cell phone bill deduction is one of the easiest ways to cut your tax bill and boost your savings. In this article, we’ll show you how to claim your cell phone bill deduction, what percentage of your mobile expenses you can write off, and how to keep your records in tip-top shape for the IRS. The cell phone bill deduction is available to anyone who uses their phone for business purposes, from answering client calls and emails to managing social media and tracking expenses on the go. To claim this deduction, you’ll need to figure out what portion of your cell phone use is for business versus personal, keep detailed records, and report your deduction on your Schedule C if you’re self-employed or as an unreimbursed employee expense if you qualify. With the right strategy, your cell phone can go from monthly expense to valuable tax write-off, helping you save money while staying connected.
Who Qualifies for the Cell Phone Bill Deduction?
Anyone who uses their mobile phone for business purposes can potentially claim a deduction. This includes:
- Freelancers and independent contractors
- Small business owners
- Gig economy workers (like DoorDash, Uber, Instacart)
- Remote employees (with unreimbursed business expenses, if eligible)
How Much of Your Cell Phone Bill Can You Deduct?
You can only deduct the percentage of your cell phone bill that relates to business use. For example, if you use your phone 60% for business and 40% for personal, you can only deduct 60% of your total bill. Keep a log of your calls, texts, and data usage for at least a few months to establish your average business use.

What Cell Phone Expenses Are Deductible?
- Monthly service charges (proportionate to business use)
- Phone purchase or lease costs (depreciated over time if the phone is expensive)
- Accessories used for business (like car mounts or Bluetooth headsets)
- App subscriptions for work purposes
