Supplementary and omitted assessments
Supplementary and omitted assessments reflect any increase in assessment due to an addition on or improvement to a property. If your property is a newly constructed home, it is likely your initial assessment is for the value of the land only. When these situations occur, an assessor from the Municipal Property Assessment Commission (MPAC) will assess any additional value.
When you receive your supplementary or omitted tax bill it will be retroactive to the date you purchased the property. Legislation allows MPAC to add omitted assessments for the current year and the preceding two years.
