I work for Amazon Flex, what should i keep track of apart from my mileage?

[boogieman5151]

I've heard doing the standard rate of .55 cents a mile covers everything including gas etc

For the standard deduction: Keep mileage logs of your business miles. This deduction covers gas, repairs, oil and depreciation on your vehicle

For the actual expenses method: Keep mileage logs of your business miles and all receipts relating to the operation and maintenance of your vehicle.
