<prompt> Human: My wife started selling some crafty things on Etsy starting January 2015 and has accumulated about 8k over the course of the year. I usually do the taxes, but I wasnt diligent in keeping up with this since I believed it to just be a hobby.Now tax season has obviously rolled up, and Im left to wonder what I should do with this. My W-4 reflected only one spouse was working and my wife hasnt paid any quarterly taxes at all. Also, she didnt really keep any records at all for deduction purposes. I made about 33k before taxes this year, and my own taxes would be relatively cut and dry, but this adds a little more complexity to it.Edit: I really appreciate the advice for the coming year. Is there anything you suggest for the current filing? Im not sure whether to be filing separately to negate her tax debt or jointly for the plethora of other benefits.Before I go to a tax professional, is there any advice that can be offered for a situation like this?  <response>: Hobby vs BusinessTurbo Tax Home Business may be a good option for you to be guided through the process of what you can deduct. It can also help you realize what records need to be kept for next year.For instance, the 8k sounds like revenue. She can deduct her cost of revenue materialssupplies, mailing, mileage to the post office if applicable, etc to get profit. You will then owe taxes on that profit. Warning, self employment taxes are high
