Delaware homestead exemption

Delaware's senior school property tax credit pays 50% of the regular school property tax, up to $500, for owners 65 or older who have been domiciled in Delaware for 10 consecutive years (3 years if they became domiciled between 2013 and 2017) and pay the bill in full.

This is the property tax homestead exemption, not the homestead exemption that protects a home from creditors in bankruptcy.

Does Delaware have a homestead exemption?

Delaware's senior school property tax credit pays 50% of the regular school property tax, up to $500, for owners 65 or older who have been domiciled in Delaware for 10 consecutive years (3 years if they became domiciled between 2013 and 2017) and pay the bill in full. The calculator does not subtract it: the rates already reflect the exemptions owners received.

Why might a Delaware tax bill differ from this estimate?

The rate is what owner-occupiers in Delaware paid on average in 2020 through 2024, as a share of their homes' value. An actual bill depends on the home's assessed value, the levies where it sits and the exemptions its owner claims.

What the calculator leaves out

The rate is the total real estate tax owner-occupiers reported paying divided by the total value they reported for their homes, not a tax rate set by law.
The rate already reflects the exemptions, caps and credits typical owner-occupiers received, so the calculator does not subtract a homestead exemption again.
An actual bill depends on the home's assessed value, the levies where it sits and the exemptions its owner claims.
Survey estimates for small counties have wide margins of error.

Rates and medians are American Community Survey 2020-2024 5-year estimates: taxes owners paid in those years, not 2026 bills.
