Property taxes are a significant ongoing cost for every homeowner in Hawaii, and understanding how they work can help you budget accurately and avoid surprises. Mililani falls within the City and County of Honolulu, which has its own tax classifications, rates, and exemptions. Here is a clear breakdown of how property taxes are calculated and what you can expect to pay as a Mililani homeowner.

How Honolulu County Assesses Property Taxes

Property taxes in Honolulu County are based on the assessed value of your property, which is determined annually by the Real Property Assessment Division. The assessed value may differ from your purchase price or market value. Tax bills are issued twice a year, with payments due in August and February.

The tax year runs from July 1 through June 30. The assessed value used for your tax bill is based on the property's value as of October 1 of the prior year.

Tax Classifications and Rates

Honolulu County classifies properties into different categories, each with its own tax rate. For most Mililani homeowners, the relevant classifications are:

• Residential (owner-occupied with home exemption): $3.50 per $1,000 of net taxable assessed value
• Residential A (non-owner-occupied): $4.00 per $1,000 for the first $1,000,000, and $11.40 per $1,000 for amounts above $1,000,000

If you live in your Mililani home as your primary residence and file for the home exemption, you will qualify for the lower residential rate. Investment properties and second homes fall under the Residential A classification with higher rates.

The Home Exemption

The home exemption is one of the most valuable tax benefits available to Honolulu homeowners. If you occupy your property as your primary residence, you can apply for an exemption that reduces your taxable assessed value:

• Standard exemption: $120,000 off the assessed value
• Age 65 or older: $160,000 off the assessed value

You must file your home exemption claim by September 30 for it to take effect for the following tax year. New homeowners should apply as soon as possible after closing to ensure they receive the benefit.

Sample Tax Calculations for Mililani Homes

Here are examples of what Mililani homeowners might pay at the current residential rate with the home exemption applied:

• Home assessed at $700,000: ($700,000 - $120,000) x $3.50 / $1,000 = $2,030 per year, or about $169 per month
• Home assessed at $850,000: ($850,000 - $120,000) x $3.50 / $1,000 = $2,555 per year, or about $213 per month
• Home assessed at $1,000,000: ($1,000,000 - $120,000) x $3.50 / $1,000 = $3,080 per year, or about $257 per month

These amounts are estimates based on current rates. Actual taxes may vary as assessed values and rates are updated each year.

How to Look Up Your Property Tax Information

You can look up the assessed value and tax information for any property in Honolulu County through the Real Property Assessment Division website at realproperty.honolulu.gov. You can search by address, parcel number, or owner name. This is a valuable tool for buyers who want to estimate their tax obligation before making an offer.

Tax Considerations for Military Homeowners

If you are an active-duty military member who purchased a home in Mililani but have since been reassigned to another location, you may still qualify for the home exemption if Hawaii remains your legal residence. However, if you rent out the property while stationed elsewhere, the classification may change to Residential A, significantly increasing your tax rate. Consult with a tax professional to understand your specific situation.

How Property Taxes Affect Your Monthly Payment

Most mortgage lenders collect property taxes as part of your monthly payment through an escrow account. Your lender estimates the annual tax amount, divides it by 12, and adds it to your principal, interest, and insurance payment. If the assessed value or tax rate changes, your escrow payment may be adjusted, which can cause your total monthly payment to increase or decrease.
