Just saw this piece in today's Star-Ledger here. Here's a summary of the 21 Counties and Middlesex County by Municipality:
Total Tax Rate (excludes Garbage Dist 1 tax) 4.576 per 100 up 4.7 Cents over last year's 4.529.
(This increase was made up of 3.6 cents for the school tax, 1.2 cents for the county tax and a decrease of .1 cent for the municipality).
Ratables in 2013 of 6,997,886,834 and 2012 of 7,056,377,673.
Average Home Assessed Value - 2013 of 176,801 and 2012 of 176,704.
Hence, in 2013 - Average property tax of 8,090 (4.576 x 1,768).
2012 - Average property tax of 8,002 (4.529 x 1,767).
Anyhoo, there's a bunch more detail that you can see if you wish (not just for Edison but for all the municipalities in the state) at the NJ Department of Community Affairs website - the source used by the SL.
