Property taxes in Hawaii work differently than most mainland states. If you own a home on Oahu or are planning to buy one, understanding how the Honolulu property tax system works and how the homestead exemption can lower your tax bill is essential. This guide covers the key facts for 2026.

We are Kristy and Austin Nakamura with Kristy and Austin Home Group. We help buyers and sellers across Oahu understand the full financial picture of homeownership, including property taxes, exemptions, and how they affect your monthly costs.

How Oahu Property Taxes Work

Property taxes on Oahu are assessed and collected by the City and County of Honolulu. Tax rates vary based on the classification of your property. Owner-occupied residential properties are taxed at a lower rate than investment properties, vacation rentals, or commercial properties. The classification of your property directly affects your annual tax bill.

The City and County of Honolulu assesses property values as of October 1 each year, and tax bills are issued for the fiscal year starting July 1. If you are buying a home, property taxes will be prorated at closing based on the date of the sale.

The Honolulu Homestead Exemption Explained

The homestead exemption is one of the most important tax benefits available to Oahu homeowners. It reduces the assessed value of your primary residence, which directly lowers your annual property tax bill. To qualify, you must own the property and occupy it as your principal home for more than 270 days per year. You must also file a Hawaii state income tax return using your Honolulu address.

The basic homestead exemption for Honolulu is $100,000 for homeowners under age 65. If you are 65 or older, the exemption increases to $140,000. These amounts are deducted from your home's assessed value before taxes are calculated.

You can only claim one homestead exemption, and it must be your primary residence. Investment properties, vacation rentals, and second homes do not qualify. The application is typically a one-time filing with the City and County of Honolulu Real Property Assessment Division, but you may need to update it if your circumstances change.

How to Apply for the Homestead Exemption

To claim the homestead exemption on Oahu, file an application with the City and County of Honolulu Real Property Assessment Division. You will need to provide documentation proving ownership and that the property is your primary residence. This may include your property deed, a Hawaii driver's license with your property address, and utility bills.

The deadline to file for the upcoming tax year is September 30. If you purchase a home after this date, you can still apply, but the exemption may not take effect until the following tax year. We recommend new homeowners file as soon as possible after closing.

Note that property tax rules and exemption amounts can change. Always verify current rates and deadlines directly with the City and County of Honolulu or consult with a tax professional for advice specific to your situation.

Property Tax Considerations for Military Families

Military families stationed on Oahu who purchase a home face a common question about the homestead exemption: can you qualify if you are active duty and may PCS in a few years? The answer depends on whether the property is your principal residence and whether you meet the residency requirements during the tax year.

If you are living in the home as your primary residence and filing Hawaii state taxes, you should be eligible. However, if you PCS and convert the property to a rental, you would lose the homestead exemption and the property would be reclassified at a higher tax rate. This is an important factor to consider when running the numbers on keeping a property as an investment after a PCS move.
