A Senate committee is preparing to take up a tax cut authored by Kokomo Republican Jim Buck.
The proposal differs slightly from Governor Pence's call for a 10% cut over two-years.
Buck is recommending a nearly 12% reduction phased in over four years.
He says that would give legislators a chance to halt the tax cut if the economy sputters, or speed it up if Indiana takes in more money than expected.
Buck agrees with the governor that lawmakers should not put off debating the issue.
Both say considering many Midwestern states are discussing or have already cut their income tax, Indiana needs to follow suit to remain competitive.
