Any of you guys deduct your cell phone as a business expense? I've heard from 4 different people. 2 say they do all the time without problem (full cell phone bill, even though they ALL say they use it for personal use as well). Other guy says he deducts only a part of it, 4th guy says he doesn't deduct it at all cause it's personal use. Now if you advertise with the cell phone # and all your customer contacts are made with the cell phone #, what's the deal?
