Can someone tell me what the rules are for proper accounting of travel mileage?
If you go to work and travel to a work related location and back to work and then go home, I understand that you should be covered for the mileage from work to the work related location and back to work but not from home to work and from work to home.
Now, what if you go from home to the work related location and back home and it is shorter than if you went from work, to the work related location, then back to work?
Now, what if you go to the work related location and back home and it is longer than if you went from work, to the work related location, and back to work?
What if you go to the work related location from home, back to work then back to home?
Is there a general "rule of thumb"?
