A temporary property-tax drop can climb back later
California decline-in-value relief can lower an assessment for a while, but it can also rise again as the market recovers.
Prop 8 relief is a temporary property-tax drop. It can apply when a property’s market value falls below its adjusted base-year value.
The part people miss is the word temporary. The Board of Equalization says the assessor reviews the value each year. If the market recovers, the assessed value may rise by more than the usual 2 percent limit until it gets back to the factored base-year value. If your bill jumped after a low year, ask the assessor if this is why.
