I'm going to be filing my DBA and all my LLC paperwork so I can start writing things off and actually doing business. I'm curious, when writing off equipment that you use for work, can you write off equipment that you purchased used (just stuff I'm not going to be totally reliant on, I have a pretty strict budget to start with of about ~$4000)? Also, after talking to my mom (an avid entrepeneur), I discovered how strict some regulations are on the usage of a home office, etc. Does equipment that you purchase for business use have to be used for business only? If I go out and shoot some landscapes with the same camera I wrote off for shooting weddings, am I technically breaking the law? Sorry for all the questions, I'm just getting everything together to have a legitimate business for shooting weddings. I'm reading a lot, but some questions just have to be asked.
