In December 2011, Allegheny County announced that the first 2012 reassessment notices would be mailed on December 19, 2011, to all commercial and residential property owners in the City of Pittsburgh. This article describes what was happening at the time.
The court ordered the County to release City of Pittsburgh reassessments before January 1, 2012, so the City and Pittsburgh Public Schools could set their 2012 millage rates. Both operate on a calendar year. Most other school districts and municipalities use a fiscal year running from July to June or similar. The rest of the County would follow later.
As of December 7, 2011, the appeal deadline for City properties had not been set. In past years, the deadline had consistently been March 31. There was speculation that 2012 deadlines would be shorter, so we urged owners to watch closely for notices from the Office of Property Assessments.
The County approved an increase in its millage rate from 4.69 mills to 5.69 mills. That meant:
Some had hoped rates would fall as assessments rose. Instead, many owners faced a double hit: higher values and a higher rate.
Many clients asked about a 5% cap on revenue increases after a reassessment. As we explained at the time, the rule limited a taxing body’s increase in total revenue, not just property tax revenue. Some taxing bodies argued that expected losses elsewhere, such as lower delinquent collections, kept total revenue within the limit even as property tax revenue rose. We expected many to keep rates high out of concern about appeals.
