I work 3 1099 self employed jobs. Construction/subcontracting, music therapy, and entertaining in nursing homes. Many days I’ve done all three “businesses” in the same day using the same personal car. I have created a total mileage for each day, but don’t have them separated. Do I have to separate them and if so do they have to be accurate? Could I take the number of businesses worked in a particular day and divide it by that day’s mileage, even though it isn’t exactly how much each had, but it totals to the right amount? For instance 150 miles on a certain day, 50 -construction, 50-Entertainment, 50-music therapy. Does it matter or do I need to be more accurate?
