On narrow screens the ratio column is hidden. ## Reading the table Use the **general rate** with your assessed value to estimate a bill: assessed value × general rate ÷ 100. The **effective rate** is the State's comparison figure, and the Division says it is not for computing a bill. The widest gap in Sussex County is Hamburg Borough: general 5.135, effective 2.939, with assessments averaging 52.31% of true value. The **average residential bill** is the Division's average for residential properties in the town, not a typical bill for any one house. ## Appeals in Sussex County Assessment appeals go to the **Sussex County Board of Taxation**: 83 Spring Street, Suite 301, Newton, NJ 07860, phone (973) 579-0970 ext. 1573 ([State contact list, September 2026](https://www.nj.gov/treasury/taxation/pdf/lpt/cb/ctb-statewide.pdf)). The Division's [appeals page](https://www.nj.gov/treasury/taxation/lpt/lpt-appeal.shtml) gives the filing deadline as April 1, or May 1 when the town has had a revaluation or reassessment. To win, an owner must show the assessment doesn't fairly reflect true market value or falls outside the common level range: the town's average ratio plus or minus 15%. The ranges certified for tax year 2027 are in the [Chapter 123 certification](https://www.nj.gov/treasury/taxation/pdf/lpt/chap123/2027CH123.pdf); it notes that ratios over 100% are considered 100%, which affects Hamburg Borough, Stanhope Borough here. ## Where Sussex County stands The median Sussex County town's effective rate, 2.300, is above the statewide median of 2.140 across all 564 municipalities.
