Missouri House Democratic Leader Mike Talboy is criticizing the state auditor for concluding the cost of replacing the state's income tax with an expanded sales tax is unknown.
Auditor Tom Schweich said last week he did not believe an accurate cost estimate could be calculated for the tax proposals because it would require too many assumptions.
Schweich, a Republican, says it's unclear how consumers would react to the tax change. He also says the proposals also would require lawmakers to make decisions that currently cannot be predicted.
Talboy, a Democrat from Kansas City, says it's "puzzling" that Schweich could not develop a cost estimate and urged him to try again.
Schweich says no objective auditor could develop an estimate. He says Talboy's criticisms are politically motivated.
