Some increases result from correcting inequities such as improvements to property performed without building permits and therefore not reflected in the assessments prior to the revaluation.
If market values in your area have not risen as much as in other areas, or your property is currently overvalued when compared with the comparable properties, your share of the tax burden would be reduced as a result of revaluation. The assessed value is only one component in determining tax rate. The other is the amount to be raised in taxation is each government's yearly budget that each of the four government's (local, county, school and regional school) determine to be required to operate. When each year's budget reflects an increase in the amount to be raised, regardless of whether a revaluation is implemented, one pays more taxes.
