PAUL DAVENPORTPHOENIX (AP) â¿¿ Arizona lawmakers approved tax cut legislation Thursday as they wrapped up their regular session, despite complaints that they courted danger by moving forward with proposals put on their desks just hours earlier. The Legislature also completed action on Gov. Jan Brewer's proposal to redesign the state government's personnel system by making it more like those of private businesses. The Senate approved the changes on a 21-9 vote Wednesday, and the House's 38-18 vote Thursday sent it to the governor. The Senate approved the main bill in the tax package on a 19-9 vote, nearly along party lines. The House vote was 38-18. The package's centerpiece is a phased-in 25 percent reduction in the state individual income tax on capital gains. Capital gains are profits on investments, and supporters said that part and other parts of the package should spur economic development. "This will contribute to the pro-business atmosphere of Arizona," said Sen. Al Melvin, R-Tucson. "We need to get it done now because our people need to get back to work." Critics questioned whether the state will actually benefit, and some lawmakers said they weren't given time to study large amendments formally proposed and adopted Thursday after last-minute negotiations. "This is ridiculous. This is how bad things happen when we don't run things through the process," said Sen. Ron Gould, R-Lake Havasu City. "I don't know what's in this bill." Sen. Steve Yarbrough, a Chandler Republican and one of the plan's architects, acknowledged that some parts were only assembled Thursday. But he said all the issues involved were discussed throughout the legislative session when lawmakers consider earlier versions of that bill and others. Other parts of the package included letting businesses claim a bigger deduction from the property tax on business equipment and creating a new tax credit for investments in new manufacturing plants, research facilities and corporate headquarters.
