Is It better to track miles I put in my car or gas for taxes as I’m a lyft driver. I work 10+ plus a day, 35$/day on gas vs 400+ miles. Which is better?

Let me share some insight about tracking mileage in QuickBooks Online, @userrdannyboy99.

The best way to keep track of mileage for taxes is to have a contemporaneous mileage log. It means you have to record it every day along with a description including the time and date of each trip. At the end of the year, figure out your kilometers driven for work as a percentage of your total kilometers driven. 

I also suggest getting in touch with your accountant so you’ll get the best advice on which best to track mileage for taxes.
