Company requires me to use my personal cell phone to work. Writeoff?
Not authoritative, but according to TurboTax: If your new cell phone acts as both your business and personal phone, you are only allowed to deduct the portion used for business from your taxable income. It’s important for you to hang on to your itemized phone bill and receipts to ensure that you’re deducting the right amounts and to keep records of your deduction. Since the usage you're describing sounds like a very small amount of the overall usage, it will probably be difficult to justify a business expense deduction.
