MONTGOMERY, Ala. (AP) -- An Alabama Senate committee is considering changes to a measure that would allow companies to use some of the income tax they withhold from employees to make new hires or expand their businesses.

Income tax revenues go to the Education Trust Fund under the state constitution. The committee heard testimony Wednesday on a proposed constitutional amendment that would allow some income tax to be used for tax credits. The committee did not take a vote.

Greg Canfield, head of the Alabama Development Office, says a new version of the bill would address some opponents' concerns over a provision that would reward companies for retaining existing jobs without creating new ones.

Opponents also testified that they worry the plan would take away money from public schools.
