can i write off my phone

TL;DR

You can write off your phone expenses if they are used for business purposes, but you must separate personal use from business use and only deduct the business portion.

Detailed Answer

Phone expenses are deductible when the phone is used for business purposes. If you use your phone for both personal and business reasons, you can only deduct the portion that is used for business. For example, if 60% of your phone usage is for business, you can deduct 60% of your phone bill. It's important to maintain records that substantiate the business use, such as call logs or a detailed breakdown of usage. Edge cases include situations where the phone is primarily used for business, in which case the entire cost may be deductible. However, if the phone is provided by your employer and you are reimbursed, you cannot claim a deduction.

Where to Put It on the Tax Form

Schedule C, Line 25 for sole proprietors, or as an unreimbursed employee expense on Form 2106 if applicable.

Real World Example

A freelance graphic designer uses their smartphone for client communications, project management apps, and social media marketing. They determine that 70% of their phone usage is for business. If their monthly phone bill is $100, they can deduct $70 per month, totaling $840 for the year.

Calculation Required

A calculation is required for this deduction.

To calculate the deductible amount, determine the percentage of phone use that is business-related. Multiply your total phone bill by this percentage to find the deductible amount. For example, if your phone bill is $100 and 70% of usage is for business, the deductible amount is $70.

Audit Risk & Documentation Tips

Moderate audit risk. Keep detailed records such as call logs, billing statements, and any documentation that supports the business use percentage. Consider maintaining a usage log for a representative period to substantiate your business use percentage.
