Cumberland County officials want taxpayers to know that property tax bills will be arriving later than normal this year, due to a delay at the state level. Normally, the bills are mailed by early July to allow taxpayers several weeks before the August 1st due date. That due date will now be extended to 25 days from the time the tax bills are actually mailed. Counties and municipalities throughout New Jersey had to delay setting the 2011 tax rate after an additional $150 million of school aid became available for the state’s non-Abbott school districts. A letter from Cumberland County Administrator Ken Mecouch and a memo from the State Department of Community Affairs went out to the mayors of all of the county’s municipalities and townships explaining the delay.
