We are both “Semi-retired” and file Schedule Cs. We both took a trip for business. However, we have two cars and the “other” car is my spouses. I’m not asking if we double the mileage (to get that out of the way), I’m asking since the car is listed as the one I primarily use, and for business, can I just deduct that mileage as since we’re filing jointly? (And we actually both did business at the final destination, though his was more involved … we only have meals and transportation as lodging was with friends).
