Short answer
Depends. Cell phone costs may be tax deductible when the phone is used for business and you can reasonably estimate the business-use portion.
If your phone is used for both personal and business purposes, you generally deduct only the business-use share.
Who this typically applies to
- Self-employed / freelancers using a phone for clients, scheduling, invoicing, or business apps
- Independent contractors who rely on calls, texts, GPS, and job coordination for work
- Small business owners using their phone for sales, customer support, or operations
Employees are often more limited. If your employer reimburses your phone costs, you generally wouldn’t deduct the same amount yourself.
When a cell phone is more likely deductible
- You use the phone regularly for business (calls, texts, email, apps, navigation, two-factor authentication)
- The expense is ordinary and necessary for your work
- You can estimate a reasonable business-use percentage (or have a separate business line/device)
- The cost is not fully reimbursed by an employer or client
When a cell phone is not deductible (or risky)
- The phone is used only personally (no business purpose)
- You claim 100% business use on a phone that is clearly used personally too
- You can’t explain how you estimated business use
- Your employer fully reimburses the cost you’re trying to deduct
Example: estimating the deductible portion
Many people deduct phone costs by using a consistent business-use percentage. What matters most is that the method is reasonable and you can support it with notes.
Example
- Monthly phone bill: $90
- Estimated business use: 50%
- Estimated deductible amount: $45/month
If you have a separate business line or a dedicated work phone, your deductible portion may be simpler to justify.
What records to keep
- Monthly phone bills/statements showing the amount paid
- A brief note describing your business-use estimate (and how you arrived at it)
- Optional supporting context (for example: client call patterns, work schedule, or a separate business line)
FAQ

Can I deduct the entire cell phone bill?
Usually no. If you also use the phone personally, you generally deduct only the business-use percentage.
What records should I keep for a cell phone deduction?
Keep phone bills and proof of payment, plus a reasonable method for estimating business use (notes, allocation method, or evidence of a separate business line).
