My MIL is a licensed tax preparer. She has a business out of a mortar office. She has been doing this for forty years. She knows all the laws. She is one of the few tax consultants that can go before the IRS. Not every tax consultant has that ability. Usually you are on your own when you get audited. And I'm not declaring my house, only a part of my sewing room. She explained all that to me. I think everyone thinks I'm writing off every item I buy that has to do with quilting. I'm only writing off the quilts I sell. And I do take a loss with every quilt when I add in the hours I spent making them. I use $15 hour for making the quilt, which isn't very much for something personally made compared to store bought.
