Washington state senators want more scrutiny of the tax breaks that the Legislature passes.

A proposal approved Thursday would require tax preferences to have both an expiration date. It would also require lawmakers to include a provision explaining the intent of the tax break.

Senate Majority Leader Rodney Tom says the bill will bring more accountability to the tax breaks that lawmakers approve. He says the intent information will allow officials to better assess whether the tax incentives are helping achieve the Legislature's goals. He says that information will allow lawmakers to make better decisions about whether the tax preferences should be extended.

The Senate approved the measure unanimously, sending the plan to the House.
