I believe preparers who put most expenses on the "other" line have a method to their madness. A detailed list of expenses helps you know what to look for the following year and to catch anything that's missing. If someone has a service contract for their HVAC and you lump it in with utilities, you might not remember to ask about the cost the following year. And some of the categories on the C, and the E for that matter, are so broad you're sure to miss things. "Office expense," for example, includes paper, toner, postage, maybe the IT guy and window washers, etc. If the total seems too high it could raise a flag, so maybe it's best to break out a few of the included items and put them on "other." There most be a middle ground for using that line.....
