How it works

The starting point is assessed value, which reflects the county’s determination of fair market value for tax purposes. Net taxable value is generally assessed value minus any applicable exemptions. Kauai County applies tax rates by property class, such as owner-occupied and non-owner occupied categories, and some classes may use value tiers. This estimator multiplies the taxable value by the rate for the class you select or provide.

Examples

If a property has a taxable value of 650,000 and the applicable class rate is 0.0035, the estimated annual property tax is 2,275. If another property has a taxable value of 1,200,000 and a different class rate of 0.0060, the estimate is 7,200. Results change depending on both classification and the net taxable value after exemptions.

Limitations and important notes

This tool provides an estimated property tax and does not reflect an official tax bill. Kauai County uses property classifications and may apply tiered rates or eligibility-based exemptions. Because exemptions and class assignments depend on property use and owner status, the actual tax bill may differ from this estimate.
