A bill to increase the gas tax in Missouri by 12.5-cents passed the Senate yesterday. The state’s current 17-cent per gallon tax on gas and diesel fuel would increase incrementally 2.5 cents per gallon annually for five years resulting in a 29.5 cent per gallon tax. Missouri currently has the third-lowest gas tax and hasn’t increased the tax in nearly 25 years. The measure now heads to the House for approval.
