another trust question

I just included a car, a smart printer, and a smartphone to my UBOT and all three of these items are used for business so the upkeep and maintNance on them are business related how does this effect tax write offs? I have never dealt with taxes before but I know a business has to be reported to the irs, right? Also I had the trust in existence since 2014 but there was literally no movement of me or the trust from that Time until last month April,2016 when I got my EIN #. What will happen since I never reported to the irs in those two years or does it not matter since it is a private trust? And should I put minor stuff into my trust like clothes, shoes, etc...?
