<prompt> Human: In the past month I got two jobs, equalling about 45-50 hours a week. At Job A I am an employee, but there is no provided office. Ive figured out that I can deduct my home office from my rent. Unfortunately my personal computer is no longer functional, and I need one for work. Job B hired me on as an independent contractor. I can work in their office or at home, when I work is at my choosing, and they provided me with a laptop for work either permanently or until I get my own work computer. I need to get a work computer for my other job, so Im currently using the computer provided by Job B to do work for Job A. My question is, as a part time independent contractor to only one business, am I self employed? Do I have to register as a business? If I dont, can I still buy a computer as a business expense? Ive never done independent contract work before, and I am having trouble figuring out how this all works.  <response>: Youre probably violating an agreement with one job by using its computer for the other.
