General Information

Understanding Real Property Taxes
Each year Kauai property owners make an investment in the County when they pay their real property taxes. Every dollar is returned in the form of vital services including police and fire protection, street maintenance and recreational facilities and activities.

Assessed Values
Every year, properties are assessed at 100% of fee simple market value using the cost and market approaches to value. Real property taxes are calculated by multiplying assessed values less any exemptions by the appropriate tax rate. Once a year, on December 1st, assessment notice(s) are mailed to property owners. The notice lists the assessed value, exemptions, net taxable value and general land classification.

Classification for Tax Rate Purpose

Property is classified based upon its highest and best use. Properties receiving homeowner exemptions are the exception. Properties which have been granted a homeowner exemption may be classified in one of two overclasses, "Homestead' or "Commercialized Home Use, " based upon all actual uses of the property.


If you don't agree with the assessed value or tax classification on your assessment notice, any owner shall first appeal to the Real Property Tax Division Board of Review. The cost for each appeal is $75 and must accompany each timely claim for the appeal to be deemed 'filed' to the Board of Review. Appeals to the Board of Review shall be filed by DECEMBER 31st or within 30 days of a corrected assessment. Even though you have an appeal pending, you must pay all taxes by the due dates or you will be charged penalty and interest.
