(AREA) -- State Senator Mike Green of Mayville introduced a package of bills Tuesday to exempt veteran service organizations from charging or paying sales tax on fundraiser revenue. Current state law provides an exemption to 501(c)(3) nonprofit organizations if their annual revenue is less than $5,000. Green's legislation would make veteran groups eligible for the exemption and increase the allowable sales threshold for all groups to $25,000. The threshold has not been updated since the 1990's. Veteran service organizations include the Veterans of Foreign Wars, American Legion, and American Veterans, among others. Although VSO's provide extensive charitable and honorary services to active duty service members and local veterans, they are not offered the sales tax exemption. Senator Green says many of these organizations are struggling financially due to declining membership, increased costs and tough economic times. During the 2011-12 legislative session, Green introduced a similar bill after a local veterans group in his district was subjected to the sales tax on proceeds raised during a fundraiser for a soldier severely wounded during combat operations in Afghanistan. The 31st Senate District includes Arenac, Bay, Huron, Sanilac and Tuscola counties.
