A key House committee backed a series of tax breaks Thursday, setting them up to pass the full chamber before next week’s deadline.

Bills generally must pass one chamber by the 30th day of the session, which may come next week.

One of the most closely watched of the tax break bills would continue an exemption on parts and equipment used to repair and maintain aircraft registered outside of Georgia. Gulfstream and other companies that do such repairs pushed to make the exemption permanent.

“We are competing with other states,” said Rep. Alex Atwood, a Republican from Brunswick and the bill’s sponsor. “Until other states stop giving these exemptions, Georgia has to compete with them.”

Leaders of the House Ways & Means Committee, however, decided against making the tax break permanent. So, if approved by the General Assembly, the tax break would be reconsidered again in 2015. It would cost state and local governments $8.9 million next year.
