IN Gov. Braun Extends Gas Tax Holiday to Maximum Allowed by Law05/07/2026You can look for a little extra relief in prices at the pump in Indiana. Governor Mike Braun extended the Indiana gas tax holiday by another 30 days and is suspending the gasoline excise tax, which will give you about a 59-cent discount per gallon at the pump because the usage tax is 23 cents per gallon and 36 cents per gallon. The decision is the longest Braun can extend the holiday on his own authority by law without a special legislative session.
