I just became legal and stated a business last Feb. and I have a question. I put magnetic signs on my car.... advertising. Essentially it's a rolling billboard. Question is, how do I write off the details I do on my own vehicle? ( can't sell detailing with a dirty vehicle
) I'm sure I can't charge myself the retail rate (doing business as DBA)
Anyone know how to go about this?
