Real property assessment notices will be hitting mailboxes soon, and if you've got questions, you're not alone. Below are answers to the most common questions Oahu homeowners have about how real property assessments are determined, how to appeal your home's assessment and more.
What is a Real Property Assessment Notice and Why Does it Matter?
First things first: The assessment is a notice, not a bill. It’s a snapshot of how the City & County of Honolulu values your property for the upcoming tax year. Even long-time homeowners should take a close look each year, as exemptions or tax classifications sometimes need updating to reflect your current situation. Understanding your notice early can help you anticipate tax changes and avoid overpaying.
The City and County of Honolulu's Department of Budget and Fiscal Services Real Property Assessment Division sends property assessments every year on December 15. The notice provides the property’s ID/tax map key, assessed value, tax classification, applied exemption amount, applicable special assessment and net taxable value. The first tax bill for the next tax year will be sent in July 2026
The City and County made a video that explains the real property assessment notice, how to file an appeal and the four reasons, or grounds, for appeal.
How is My Home's Value Determined?
The net taxable value is taxed per $1,000 of the value at the property’s applicable property classification tax rates classification tax rate. Assessed values for 2026 are based on the home's value as of Oct. 1, 2025, and are calculated based on sales of similar properties through June 30, 2025.
Helpful Definitions
- Assessed Value: The County’s estimate of your home’s fair-market value based on comparable sales through the prior June
- Exemptions: Deductions for owner-occupants, seniors and other groups that can reduce your taxable value by $100,000 or more
- Net Taxable Value: The assessed value minus any exemptions (this is the value the tax rate is applied to)
- Tax Class & Rate: Your property’s classification (owner-occupied, investment, condo-hotel, etc.) determines which tax rate applies
How Do I Appeal My Home's Assessed Value?
If you disagree with the assessed value of your home, you can file an appeal. The most common grounds for appeal is disagreement with the assessed value. If you believe that your property's assessed value is more than 10% higher than the property's actual market value—and you can back up your claim— then you may have grounds for an appeal.

How Can I Lower My Property Tax?
Aside from appealing your property's assessed value, there are a few other ways you could potentially lower your property taxes.
First, if you live in the property you own, be sure to file your homeowner exemption if you haven't done so already.
If you own investment properties, classified as "Residential A," note that there are two tiers that are taxed at different rates. If your investment property is valued at more than $1M (Tier 2), you may want to consider using a 1031 exchange to reinvest in two or more properties that fall into Tier 1 and are therefore taxed at a lower rate. Talk to your Locations agent or attend one of our seminars for real estate investors to learn more.
