I have forced myself to write down the mileage to each location. Yes, I still mess up when I'm in one town and I have a few shops in said town.
I do not work for anyone else so my mileage is work mileage 85% of the time.
Truthfully, because of my convoluted tax return I leave it up to the family accountant.
But this is how it used to be when I did taxes. If you have a job gives a W2, you cannot take your mileage getting there. If you have a second job and it may also give you a W2, you are allowed to take the mileage from the 1st job to the second job. it was always fuzzy for me about the trip home.
I have read the IRS is trying to cut back on mileage allowances. Whether that is true or not, I have no idea.
My mileage is huge so the accountant uses her discretion,. This year my mileage will definitely be over 30K.
I believe Flash has given the best advice so far.
Live your life in such a way that when your feet hit the floor in the morning; the devil shudders...And yells OH #%*+! SHE'S AWAKE!
