<prompt> Human: Im filing as just an individual. In 2016 I made 99K and in 2017 I made 92K. Where I earn commission, my tax withholdings are higher because my income cant be predicted. Last year I wrote off my cell phone bill and mileage and ended up getting around 4000 or so back. This year I was expected to get about the same but my tax lady made some recommendations and bumped up my tax refund up to 8300. To be honest, Im not exactly sure what she did. I asked her and she said she used the depreciation on my car from mileage and then side income where I lost money.What I dont want is to get this money and then 3 years from now have to pay it back because Im completely ignorant of how things operate, thats why Im using a professional or at least thats how I perceive it. Should I pull out? Is this normal?Edit: A lot of good responses here. A side note is I have 3 different jobs. My primary one where I have to drive to events, businesses, and customer addresses. I basically drive my vehicle outside my own city all the time or if I drive to my office its also located out of town. This one is 100 commission with a paycheck draw. My secondary one which is a podcast. And my 3rd one as a computer repair business I use for friends and family and some customers if I like them. I take a loss on the secondary incomes as I do them mostly as hobbies but I still do make some money on them. The podcast costs a lot and I dont have any real advertising. I didnt give my tax lady my tax ID on my podcast so I think shes filing it as something else. But Im really ignorant about all this, thats why Im relying on her to handle it.Assistant: I wouldnt worry about it. If this person is a CPA, then they make their living off this stuff, and they have their reputation to worry about if an audit produces a bad result for the client. Human: Okay that makes me feel better then.  <response>: To be honest, though, you should check what they are filing. You are right about that part. I just wouldnt spend time worrying about it. There are CPAs who are fishy, but if there is justification for what is filed, that is all that matters. Dont want a CPA who is making up mileage and such, though.
