As a small business owner in 2025, you likely rely heavily on your cell phone. The good news is, you can potentially deduct the business-use portion of your cell phone expenses.

The Basic Rule
If you use your cell phone for work, you can deduct the business-use portion as a business expense. You can’t deduct personal use, but the business-related portion can reduce your taxable income.
How to Calculate the Deduction
To deduct the expense, you need to calculate what portion of the phone usage is actually for business. For example, if your bill is $100 for two phones (you and your spouse), your cell phone cost is $50. If you only use the phone part-time for business, only that portion is deductible.
Important Considerations
- Documentation: Maintain supporting documentation to meet IRS criteria.
- Personal vs. Business Use: You cannot deduct personal use.
Examples
Here’s an example to illustrate: Suppose your monthly cell phone bill is $150. After reviewing your call logs and data usage, you determine that approximately 60% of your phone use is for business-related activities like client calls, emailing suppliers, and managing your online presence. In this case, you could deduct $90 (60% of $150) as a business expense.
What Can You Deduct?
Besides the monthly bill, other potential deductible expenses include:
- Data plans: The portion of your data plan used for business.
- Accessories: Items like phone cases, screen protectors, and car chargers, if primarily used for business.
- Apps: Subscription fees for business-related apps.
What You Can’t Deduct
Be aware of expenses you can’t deduct:
- Personal calls: Calls to family and friends are not deductible.
- Personal data usage: Streaming movies or playing games on your phone for personal entertainment.
- The cost of the phone itself: This is generally considered a capital expense and may need to be depreciated over time (consult a tax professional).
Record Keeping is Key
The IRS requires you to keep accurate records to support your deductions. This includes:
- Phone bills: Keep copies of your monthly bills.
- Call logs: Review your call logs to determine the percentage of business use.
- Calendar entries: Document business-related calls and meetings.
- Receipts: Save receipts for any accessories or apps you purchase for business use.
When Should You Consider a Separate Business Phone?
If your business use is substantial, consider getting a separate cell phone solely for business purposes. This simplifies record-keeping and allows you to deduct the entire cost of the business phone and its associated expenses.
Consult a Tax Professional
Tax laws can be complex, and this information is for general guidance only. It’s always best to consult with a qualified tax professional to determine the specific deductions you’re eligible for and to ensure you’re complying with all applicable rules and regulations. They can provide personalized advice based on your individual circumstances and help you maximize your tax savings.
