What the data shows for Delaware

Primary signal

A median-home worked example anchors the scale

A home at Delaware's median value of $352,000 pays roughly $1,760 a year at the 0.50% state average rate, but about $2,499 at New Castle County's 0.71% rate versus $1,126 at Sussex County's 0.32%.

Decision signal 2

The statewide rate sits in the low-burden group

Delaware falls in the lowest third of states for effective property tax rates (43 of 51), averaging 0.50% versus 0.92% nationally.

Decision signal 3

County rates diverge enough to change the estimate

Rates roughly double from Delaware's cheapest county (0.32%) to its most expensive (0.71%).

Decision signal 4

The median annual bill has a monthly reading

At the median, a Delaware homeowner's $1,768 annual bill works out to about $147 a month on top of mortgage, insurance, and utilities, one reason the effective rate matters as much as the sticker price when comparing locations.

Decision signal 5

More counties sit below the national rate than above

Of the 3 Delaware counties with measured ACS 2024 data, 0 carry an effective rate above the 0.92% national average while 3 sit below it.

Reading these numbers correctly matters. An effective rate is a measured outcome, not a posted tax rate: it captures what typical homeowners actually paid after exemptions, assessment ratios, and every overlapping levy settled out. That makes it the most comparable single figure across county lines, where statutory mill rates are defined against different assessment bases and cannot be compared directly. Two counties with identical posted rates can produce very different real bills, and the reverse is just as common. Lenders use a similar logic when they estimate escrow: a percentage of value, calibrated to the taxing jurisdiction. Treat the figures here the same way, as a calibrated starting point that tells you which jurisdictions are expensive relative to home value, and confirm the exact bill with the assessor before you commit.

How This Calculator Works

The estimate multiplies your entered home value by a measured effective property tax rate: median taxes paid divided by median home value from Census Bureau ACS 2024 data, either for your selected Delaware county or for the state as a whole.

This is a representative estimate, not your bill: actual Delaware taxes depend on your assessed value, exemptions you qualify for, and municipal levies. Verify with your county assessor before making financial decisions.

Frequently Asked Questions

How does Delaware compare to the national average?
Delaware falls in the lowest third of states for effective property tax rates (43 of 51), averaging 0.50% versus 0.92% nationally.
How much do property tax rates vary within Delaware?
Across the 3 Delaware counties with published ACS 2024 data, effective rates run from 0.32% to 0.71%. That spread is why choosing your county gives a much closer estimate than the statewide average.
What is the typical property tax bill in Delaware?
The Census Bureau's state-level ACS 2024 estimate puts Delaware's median annual property tax at $1,768, on a median home value of $352,000. A home at a different price point scales roughly proportionally, which is what this calculator computes for you.
How is my Delaware property tax estimate calculated?
The estimate is your home value times an effective rate measured by the Census Bureau (ACS 2024): median taxes actually paid divided by median home value. County selection swaps in your county's own rate; otherwise the 0.50% Delaware average applies. Even in a low-tax state, individual assessments and exemptions shift the real bill.
Does this estimate include exemptions?
Not individually. The measured rate already reflects the blended effect of exemptions across each county, but your own homestead, senior, veteran, or disability exemption is not applied. If one covers you, expect an actual Delaware bill somewhat below the estimate. Confirm with your county assessor.
