Delaware Property Tax Calculator
Delaware property tax bills are assembled from a county levy, a school-district levy, and — inside town or city limits — a municipal one, each applied to the assessed value on file with the county. Homeowners who think that value is wrong can appeal it, and relief programs exist for some seniors. This page won't quote your exact bill; it estimates one from county medians. Pick your Delaware county above, type in a value, and start from there.

How property tax works in Delaware
- Three layers can appear on a Delaware bill — county, school district, and municipality — all applied to the county-assessed value.
- Appeals address values that look wrong; senior-focused relief programs reduce bills for those who qualify.
Methodology
Rates are aggregate-derived from the Census Bureau's ACS 2024 5-year American Community Survey (total real-estate taxes paid ÷ total home value, by county). This is a statistical estimate, not a bill lookup — actual property tax bills vary by city, school district, and special-district levies layered on top of the county rate, and by any homestead, senior, veteran, or other exemptions you qualify for. Delaware ranks #40 of 51 (including DC) by statewide average effective rate, where #1 is the highest.

Frequently asked questions
How is property tax calculated in Delaware?
The county keeps an assessed value on file for your property, and the county, your school district, and (if you live in one) your town or city each apply a rate to it. The pieces are billed together, so the school and municipal shares matter as much as the county share.
How much property tax will I pay in Delaware?
That varies with your county and school district. For a quick answer, choose a Delaware county above and give it the home's value; annual and monthly estimates emerge from the county median.
Can I lower my Delaware property tax bill?
Qualifying seniors can access relief that reduces what they owe, and any owner may appeal an assessment through the county if the value on file seems out of line with reality. Appeal windows are limited, so review your assessment notice promptly.
Are property taxes deductible?
They are for itemizers: property tax is one of the state and local taxes the federal SALT deduction covers, capped at a level set by federal law. Consult current IRS rules for the cap.
