As property owners across Sussex County begin receiving their 2026 tax bills, officials have unveiled a new online tool to help residents understand how those bills are calculated—especially following the county’s long-awaited property reassessment.
The updated tax calculator, now live on the county’s website, provides parcel-specific estimates using real assessment data and finalized tax rates.
It replaces an earlier version that relied on projections, offering users a more accurate breakdown of what they owe and why.
The reassessment, the first in decades, has led to changes in many property valuations, which could mean increases—or decreases—in tax bills.

County Finance Director Gina A. Jennings said the new tool aims to bring clarity and transparency to the process.
“There are multiple reasons beyond just the assessment that could change bills, so we wanted to create a calculator that showed the difference between tax bills last year versus this year,” Jennings said. “In the interest of transparency, and to help the public understand what’s changed, we believe the new calculator will be a handy tool in providing a side-by-side comparison of the two different tax years.”
The calculator is available here.
Tax bills for the 2026 fiscal year were mailed this week, and payment is due by September 30.
