How Delaware property taxes, appeals, and exemptions work.

Property taxes are usually based on a local assessment of your property value, multiplied by local tax rates, and adjusted by exemptions or caps where available. The process is administered locally, so county deadlines, appeal forms, and exemption rules can vary across Delaware.
