I just formed an LLC. I work a full time job besides that. I want to start an online website to generate income. Can I use my LLC to purchase a new vehicle then write that off? I also rent, I want to do business from home, could I write that off as well? How do I got about writing it off? Should I keep track of what I spend with my company, start a credit card account with it? what if I take personal money, and give it to my LLC. Can I personally write that off?

Thanks for the help.
