New Castle County Modernizes Parcel Reassessment Submissions Through Automation

New Castle County's Assessment Department values and taxes approximately 212,000 properties in Delaware's most populous county, including 7,500 commercial, income-producing parcels that require detailed income and expense data. The department hadn't reassessed those income-producing properties since 1983, and the old paper process was producing a high error rate that kept the county from getting an accurate picture of its own tax base.

• Last reassessed in 1983, using long paper forms and attachments
• Manual calculations resulted in a high error rate
• Forms required wet signatures and lengthy manual database entry
• The county couldn't get an accurate picture of its own tax base

• Form logic renders only the fields relevant to each property, reducing errors
• Accessible through the county portal or a QR code scan
• Integration with the property records database validates name and lot number instantly
• A built-in calculator computes expenses automatically
• Electronic signatures replaced wet signatures
• A signed PDF is emailed to the applicant automatically upon submission
• Paper submissions were still accepted as a fallback during the transition, so the shift wasn't disruptive on day one

• Form and workflow built and deployed in three weeks
• Manual data entry reduced by over 50%
• Data for 7,500 commercial properties captured and centralized
• Submissions searchable in seconds, supporting audits and formal appeals
• The county plans to expand the process to additional property types
