Ways to lower your bill in Delaware

  • Homestead exemption or credit. Delaware homeowners can usually reduce the taxable value of the home they live in. You apply once with your county assessor, and the local deadline is often in the first months of the year. How homestead exemptions work
  • Senior, disability and veteran relief. Extra exemptions, freezes or credits are common for owners 65 and over, people with disabilities and veterans with a service-connected disability. Many need a separate form. Senior relief explained
  • Appeal a high value. If the assessed value is above what similar homes sell for, you can appeal for free, within a short window after the notice arrives. How to appeal

Amounts, income limits and deadlines change, and many programs are run county by county. Your county assessor's office can confirm what you qualify for.
