I am Roger Chartier,

I have a great interest in the Mileage Allowance as I use a lot of miles on my vehicle that are business related and I am a Sole Proprietor.
I find that because the van is paid for, I get about 21 MPG, and my cost to operate it is low.
This causes the Mileage Allowance or Standard Mileage Rate for business to be worthwhile.
So, as per this article, it can be seen that there are multiple ways that the IRS allows us to gain an advantage on using our vehicles for business.
Let me mention the two alternative methods that the IRS allows us, in certain cases, the use of our car, pickup truck or panel van to gain an advantage tax wise for our miles.
