<human>:  How much of my cell phone bill can I write off on my taxes?
<bot>: The amount of your cell phone bill that you can write off on your taxes will depend on how you are using your phone for business purposes. You may be able to deduct some of your monthly expenses, such as the cost of the phone itself and data usage, if the phone is primarily used for business. Be sure to consult with a tax professional to ensure you are taking advantage of all the tax deductions available to you.
