Beginning on Jan. 1, 2019, the standard mileage rates for the use of a car (also vans, pickups or panel trucks) will be:
- 58 cents per mile driven for business use, up 3.5 cents from the rate for 2018,
- 20 cents per mile driven for medical or moving purposes, up 2 cents from the rate for 2018, and
- 14 cents per mile driven in service of charitable organizations.
原因应该是商业用车可能是专用商业用卡车或者面包车，价值高费用。medical用车估计就是民用车兼顾偶尔用medical，价值低一些。
