Supplemental Tax Bill
An extra, one-time property tax bill triggered by a reassessment after you buy or renovate a home.
In plain English
In some states, buying a home (or completing new construction) triggers an immediate reassessment to reflect the new purchase price or improved value — resulting in a one-time supplemental bill in addition to your regular property tax.
New homeowners are sometimes caught off guard by this extra bill arriving separately from their regular escrowed tax payments — worth asking about if you're buying somewhere with this system.
