<prompt> Human: I began driving for Uber this weekend and discovered that you are an independent contractor when you drive as a partner. I sifted through some of their FAQs to discover taxes to the state may have to be paid quarterly. My separate M-F income should take care of Federal taxes at the end of the year but how do I know if I need to begin paying state taxes quarterly for my earnings through Uber and how would I go about doing so? Im in Colorado, USA.Assistant: You dont have to file quarterly for taxes, but what you should immediately be doing is keeping track of mileage and expenses like a dashcam you really want this, one facing inside and outside the car.I personally take a picture of my odometer for when I start the day doing Uber and Lyft, and then take another photo when I stop.Human: Thank you for the tips, especially the dash cam. That didnt even occur to me.I did find on Ubers FAQ that they will only reimburse mileage for actual trips which is recorded in the app fare details. Should I be writing off all miles from the moment I go online to when I go offline?  <response>: Should I be writing off all miles from the moment I go online to when I go offline?My interpretation is that youre traveling to the passenger, youre using the car for business. While you arent getting paid for it, youre still depreciating your car and you wouldnt be able to complete the business without some mileage that you arent being paid.However, Ive had people argue it other ways, but my interpretation is from the moment you start until the moment you get home, your car is being used for business not counting miles to your 9 to 5 job.As a 1099, your goal is to get as close to breaking even as you can. Edit: Uber only reimburses you for mileage with a passenger, however the standard irs mileage deduction is 54.5 cents per mile. You keep track of your miles so you can present it as a deduction.
