The National Marine Manufacturers Association is spreading the word about a tax incentive program for exporters.

The NMMA said the Domestic International Sales Corp. program is designed to stimulate U.S. exports while encouraging businesses to maintain and expand their facilities in this country.

The program provides an opportunity for a qualifying company to have the tax on 50 percent of its export income reduced by more than 50 percent, according to the NMMA.

Although thousands of U.S. companies take advantage of the program, the majority of companies do not, the NMMA said.
