The Presbyterian student center at UW-Madison is scrambling to convince state legislators its 51-unit apartment building deserves to remain off the tax rolls. The Legislature?s Joint Finance Committee on May 12 voted 14-2 to strip Pres House Apartments of its tax-exempt status as part of the 2011-13 biennial budget. The ministry was granted the exemption by the Legislature in a controversial move two years ago. Pres House now is rallying students, parents and alumni to contact state officials before the full Legislature votes on the budget in the coming weeks.
