What exemptions can lower your Delaware property tax?
Most counties offer a homestead exemption on your primary home. Many add relief for seniors, veterans, and people with disabilities. These lower your taxable value, so your real rate is often below the median.
Rules and amounts vary by county and change over time. Check your county assessor for the exemptions you qualify for before relying on a figure.
Why is your actual Delaware bill different from this estimate?
Three things move your bill away from the state median. Your county rate may be higher or lower than the median. Your assessed value can lag the market. And exemptions reduce the taxable amount.
