can i write off my phone

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.
