Statewide schedule — read this before you rely on it

The statute itself sets different dates by county: Kent is due June 1, New Castle and Sussex July 1, with penalties starting September 1 versus September 30. Most counties in this state follow these dates.

After the county penalty date (September 1 in New Castle, September 30 in Kent and Sussex), monthly penalties accrue: 6% plus 1% per month in New Castle and 1.5% per month in Kent and Sussex.

Each county mails a single annual bill, and state law requires the statement within 30 days after taxes become due.
