Delaware Property Tax Guide

Delaware property taxes are strikingly low by national standards. The average effective rate, annual taxes as a share of home value, sits around 0.51%, not much more than half the national average of about 0.9%. The tax is assessed and billed locally rather than by the state, so New Castle, Kent, and Sussex counties each handle their own assessments, and school districts and municipalities layer their own rates on top of the county levy.

To ballpark a bill, multiply the property's assessed value by the combined local tax rate, keeping in mind that assessed value isn't always the same as market value, Delaware counties have historically assessed at a fraction of full value and recently undertaken reassessments to bring figures current. Homeowners may qualify for relief such as a senior school property tax credit and exemptions for older or disabled residents, which trim the taxable base. Because rates and assessment ratios vary by county and district, two homes with identical market prices in different parts of Delaware can carry meaningfully different bills, so the local rate matters as much as the home's value.

Delaware Property Tax FAQ

How do I estimate my Delaware property tax bill?
Take the property's assessed value and multiply it by the combined local tax rate set by your county, school district, and municipality. Assessed value may differ from market value, since Delaware counties have historically assessed below full value, so confirm the current assessment after recent reassessments. At the statewide average effective rate of about 0.51%, the bill works out to roughly $510 per $100,000 of home value.
Who sets and collects property tax in Delaware?
It's handled locally, not by the state. New Castle, Kent, and Sussex counties assess properties and bill the county portion, while school districts and municipalities add their own rates. That layered structure is why your total rate, and your bill, depends heavily on exactly where in Delaware you live.
Why is Delaware's property tax rate so low?
At about 0.51% effective, Delaware's rate is not much more than half the national average near 0.9%, partly because the state has no sales tax pulling revenue in elsewhere and relies on other sources like corporate franchise fees. Lower assessment ratios in some counties have also historically held taxable values below market value, though reassessments are changing that picture.
Are there property tax breaks for seniors in Delaware?
Yes. Delaware offers a senior school property tax credit that reduces the school portion of the bill for qualifying older homeowners, along with additional exemptions some counties extend to elderly or disabled residents. These programs lower the taxable amount, and eligibility rules and credit caps are set at the county and state level.
