JEFFERSON CITY, Mo. (AP) — Missouri Gov. Jay Nixon says proposals to replace the state’s income tax with an expanded sales tax is the wrong way to go.

Nixon spoke Wednesday to members of The Associated Press and the Missouri Press Association at their annual Capitol media event. Nixon says the tax proposals would require raising the sales tax and levying it on purchases that currently are not subject to that tax. He says that is not smart.

The Legislature is considering the sales tax idea, and a group has filed proposals to put it on the ballot.

State Auditor Tom Schweich is responsible for estimating the cost of proposed ballot measures. Schweich said Thursday that there are too many uncertainties to know for sure how much the initiatives would cost.
