As of January 13, 2012, Allegheny County’s reassessment was back on, with a new plan: appeal now, pay later. In short, 2002 values would be used for 2012 taxes, and the new values would be used for 2013, with time to appeal in between.
Judge R. Stanton Wettick set a new appeal deadline of February 24, 2012, for all properties in the City of Pittsburgh and the Pittsburgh School District, which included parts of Mount Oliver. He also delayed using the new values on tax bills until 2013. The reassessment would proceed in 2012, but taxing bodies would not use the new values for billing until the following year.
His order of January 12, 2012, provided in part:
City of Pittsburgh and Mount Oliver owners who believed their new value was too high were encouraged to appeal by February 24, 2012, before 2013 tax bills went out. Owners elsewhere in the County expected their new values by the end of February 2012, with separate deadlines after that. The County had not decided whether to bring back informal hearings.
