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.
原因應該是商業用車可能是專用商業用卡車或者麵包車，價值高費用。medical用車估計就是民用車兼顧偶爾用medical，價值低一些。
