Supporters and critics of Missouri tax cut plans both are pointing to the results of recent tax cuts in Kansas.
Several business groups testified during a Senate committee hearing Thursday that Missouri must cut taxes to discourage employers in the Kansas City area from moving across the state line.
But opponents said Kansas revenues and education funding have suffered as a result of its tax cuts.
The Senate panel considered three proposals Thursday. One would cut taxes only on business income. Another would reduce Missouri's individual income tax rate. A third bill would phase in tax cuts for both businesses and individuals. No vote was taken.
Republican legislative leaders have made an income tax cut a priority this year after Democratic Gov. Jay Nixon vetoed last year's bill.
