Delaware Code
Chapter 11. ASSESSMENTS FOR MUNICIPAL TAXATION
§ 1105. Tax rate upon reassessment; notice.

(a) When any total reassessment of taxable properties within a municipal corporation of this State (hereinafter “municipality”) shall have become effective, a tax rate shall be computed so as to provide the same tax revenue as was levied during the prior fiscal year. That rate shall be known as the “rolled-back rate.” Any initial assessment made on new construction shall not be taken into account in determining such limitation.
(b) The ordinance establishing a property tax rate upon total reassessment shall state the percent, if any, by which the tax rate to be levied exceeds the rolled-back rate computed pursuant to subsection (a) of this section, which shall be characterized as the percentage increase in property taxes adopted by the governing body. Within 15 days of the meeting at which the ordinance shall be considered by the governing body, the municipality shall advertise, in a newspaper of general circulation in the municipality, said percentage increase in the tax rate.
