HARRISBURG (WSKG) -- When Pennsylvanians go to the polls next Tuesday, they'll have a rare opportunity to vote to change the state constitution. They'll decide via ballot measure whether to make property tax elimination an option. However, it would only be the first step in a long process. Property tax rates largely depend on how much school districts and local governments decide to exempt from taxation. Right now, state law lets them exclude up to 50 percent of an area's median home value. The ballot measure would increase that cap to 100 percent--so jurisdictions could opt to totally eliminate property taxes.
