Understanding Property Taxes in Mililani Mauka

Property taxes are one of the most important ongoing costs of homeownership, and the good news for Mililani Mauka residents is that Hawaii has some of the lowest effective property tax rates in the nation. All properties in Mililani Mauka fall under the jurisdiction of the City and County of Honolulu, which sets tax rates annually for the fiscal year running from July 1 through June 30.

For the 2025-2026 fiscal year, owner-occupied residential properties in Honolulu County benefit from a tiered tax rate structure that rewards homeowners who live in their primary residence with significantly lower rates than investors or second-home owners.

Current Tax Rates for Owner-Occupied Homes

The City and County of Honolulu uses a tiered system for owner-occupied properties:

  • Tier 1 (up to $1,300,000 assessed value): $1.65 per $1,000 of net taxable value
  • Tier 2 ($1,300,001 to $4,500,000): $1.80 per $1,000 of net taxable value
  • Tier 3 (over $4,500,000): Higher rates apply

Most Mililani Mauka homes fall within Tier 1 or Tier 2, keeping annual property tax bills relatively modest compared to mainland communities with similar home values.

Estimated Property Taxes by Home Price

Here are approximate annual property tax estimates for owner-occupied homes in Mililani Mauka after applying the homeowner exemption:

  • $600,000 home: Approximately $1,750 per year
  • $750,000 home: Approximately $2,275 per year
  • $900,000 home: Approximately $2,800 per year
  • $1,100,000 home: Approximately $3,500 per year

The median property tax bill in the Mililani Mauka area is approximately $3,013 based on recent data, with an effective tax rate of around 0.6 percent of property value. This is well below the national average effective rate of approximately 0.89 percent.

The Homeowner Exemption

One of the most valuable tax benefits for Mililani Mauka homeowners is the homeowner exemption. If you occupy your home as your primary residence, you can claim an exemption that reduces your taxable assessed value. For the current tax year, the basic homeowner exemption is $100,000, and additional exemptions are available for seniors aged 65 and older.

To qualify, you must file a claim with the Real Property Assessment Division and actually reside in the home. This exemption can save homeowners hundreds of dollars annually and is one reason why the effective tax rate for owner-occupied homes in Hawaii is among the lowest in the country.

Non-Owner-Occupied and Investment Properties

If you are purchasing a property in Mililani Mauka as an investment or rental, the tax rates are significantly higher. Non-owner-occupied residential properties face rates that can be several times the owner-occupied rate. Long-term rental properties have their own tiered rate structure as well. It is important to factor these higher rates into your investment calculations.

How Property Assessments Work

The Real Property Assessment Division of the City and County of Honolulu conducts annual assessments of all properties. Assessments are based on fair market value as of October 1 of the preceding year. If you believe your property has been over-assessed, you have the right to file an appeal. Understanding the assessment process can help you ensure you are not paying more than your fair share.
