Sussex reassessment extended one year

Contractor's staffing issues contribute to delay in completing process by deadline
May 21, 2023

Sussex County Council has approved a one-year contract extension to Tyler Technologies to complete its county real estate reassessment. The new deadline is now Feb. 15, 2025.

At its May 16 meeting, council voted 5-0 for the new contract. Currently, data collection of nearly 182,000 properties is underway, with data mailers to residents as the next step in the process.

The reassessment project was triggered by an education funding lawsuit filed against the State of Delaware and all three counties in 2018. The case was settled in 2021, with all three counties agreeing to conduct property reassessments.

Under terms of the original settlement, Sussex County was scheduled to complete its reassessment project by 2024, in time for tax bills to be issued in late summer and ahead of the annual Sept. 30 tax payment deadline. That timeline has now shifted a year.

County officials said the extension is because of higher-than-expected Tyler Technologies staff turnover. The company was awarded a $9 million base-bid contract in 2021.

“This is a tremendous lift, in any jurisdiction, but especially in a county the size of Sussex. With so many parcels, and limited staffing, it is taking considerably longer for our vendor to do the necessary work,” said Sussex County Finance Director Gina Jennings. “We want this done right – accurately and fairly – and the year extension will allow Tyler Technologies to do that.”

Currently, Sussex County property owners pay taxes based on 50% of a property's 1974 appraised value. County property tax is 10% of the annual bill, while 90% is school taxes. On average, single-family home owners pay $118 per year in county property taxes; manufactured home owners pay an average of $46 per year.
