Tax write off as independent contractor?
So I am looking into working for door dash or something and become an independent contractor. I am currently 20 and have not had a job that made 10k or more a year. (therefore have not filed for taxes ever) so, when I do start working as a delivery driver, would I still be able to write off taxes for gas? I know I would be making less than 10k when I start since I am not planning on working a lot. it's more of an extra income. Since I have not filed for taxes, I am wondering in the next year of April, do I file taxes and if so how would I? how do I even calculate how much money I spent on gas during the orders? sorry it's so many questions, I am a bit confused. thank you to anyone that can help
