Tax breaks given to banks and to people purchasing expensive cars and machinery are three areas that might be targeted.
Sen. Howard Lee, D-Orange, co-chairman of the Senate Finance Committee, said these and other tax breaks cost the state a tremendous amount of revenue that could help alleviate the state's budget problems.
He said the Finance Committee will be in charge of determining which tax benefits are needed and which ones can be removed.
Lee said loopholes were originally created to initiate a boom in some market sectors. "(We want to) ensure that we are gaining the benefit we expected when we put loopholes in place."
Lee said the tax benefits involving banks and caps on the sales tax levied on luxury automobiles are two classifications of loopholes that will be investigated.
He estimates $300 million to $400 million could be reaped from eliminating the loopholes.
Former State Treasurer Harlan Boyles said reducing tax preferences will keep the state moving forward economically.
Last week, Boyles, along with former governors Bob Scott and Jim Holshouser, was appointed to a committee by Gov. Mike Easley that will look at closing tax loopholes. The committee is scheduled to report to Easley and the General Assembly by April 15.
Boyles said reducing tax preferences is the General Assembly's best option to deal with the state deficit.
