Indiana's sales tax on gasoline will largely hold steady next month, increasing by just $0.001. But there's a bigger gas tax increase coming in July and, thanks to new legislation, several more Julys to come.

That tax rate will be 5.4 cents less than August's record-high rate of 62.4 cents, a fluctuation that comes as Indiana's 7% sales tax on gasoline is calculated monthly along with a set tax directed to road projects.

Indiana has two taxes on gasoline -- the 7% state sales tax and a tax directed to infrastructure projects.

Most businesses who sell online aren't required to collect sales tax if they don't have a physical presence in the state.
