HCS/SB 629 - This act exempts contractors from paying sales taxes on materials used in Department of Transportation projects. The sales tax exemption does not take effect until after June 30, 2007. This portion of the act is similar to SB 142 (2005) and SB 731 (2004). This act modifies the sales tax exemption for certain motor vehicles. Under current law, an exemption from sales tax is permitted for motor vehicles licensed for a gross weight of 24,000 pounds or more or trailers used by common carriers solely in the transportation of persons or property in interstate commerce. This act removes the "solely in interstate commerce" restriction, thus allowing the sales tax exemption for motor vehicles licensed for a gross weight of 24,000 pounds or more or trailers used by common carriers in the transportation of persons or property. This portion of the act is similar to SB 696 (2006). STEPHEN WITTE
