New Jersey property-tax definition
Omitted assessment
An assessment used when taxable property or an improvement should have been assessed but was omitted from the regular roll.
Worked New Jersey example
An omitted improvement can create a later bill even though it did not appear on the original annual assessment notice.
Why it matters

For homeowners
Use the term to understand what a tax or assessment record is actually saying before assuming it represents market value or a future bill.
For professionals
Keep the source and observation date with the number, verify the authoritative record, and document any calculation or professional conclusion separately.
