I have a few questions regarding my taxes. I just started a new job where I am a independent contractor working for a dispatch company doing roadside assistance.

Because I travel city to city they have made me responsible for doing a 1099. I have not had to do this before and not sure what information i will need at that time. I also do not get any reimbursement for my gas mileage. Is there something I should be tracking like my mileage or gas receipts for when I file? What else do I need to know about filing under this type of business. Thank you.
