A bill to rewrite Arizona's state income tax by eliminating most income tax deductions and flattening graduated rates into one lower rate is now poised for consideration by the full Senate.

The so-called "flat tax" bill cleared the Senate Finance Committee on a 4-2 party line vote Thursday. Republicans voted for it and Democrats against. It has already been approved by the House.

A budget staff analysis indicates that taxpayers with federal adjusted gross incomes below $100,000 generally would pay more state income tax under the bill while those with higher incomes would save.

The analysis says the bill would not significantly add or subtract from total state revenue.
