INDIANAPOLIS - INDIANAPOLIS — Indiana residents will soon be seeing an increase in prices as the gas pump.

The Indiana Department of Revenue published the gas use tax rate for the upcoming month. The tax will be increasing by 1.4 cents to 18.6 cents per gallon starting March 1.

Although the gas tax has decreased in recent months, Hoosiers have seen a significant increase over the last five years. In March 2018 the rate was 13.8 cents and 11.4 cents in March 2019.

At this time last year the gasoline tax rate was 18.4 cents per gallon.

Indiana calculates this tax by taking the average price per gallon of gasoline in the prior month and multiplying it by the state retail tax. The average retail cost of one gallon of gas last month was $2.66. This means that Indiana residents will end up paying an extra 18 cents per gallon.

The state average for one gallon of gas is currently $3.31 a gallon, ten cents lower than Tuesday’s national average of $3.40 a gallon.

The Triple-A Motor Club reports the average price of diesel fuel in Indiana Tuesday was $4.60 a gallon, a penny lower than Monday. It was also four cents lower than a week ago, 17-cents lower than a month ago, and 65-cents higher than a year ago.
