How Property Tax Works

Honolulu County operates on a property tax system that serves as the primary funding source for essential municipal services including schools, parks, emergency services, infrastructure maintenance, and public safety. Property taxes in Honolulu County are administered by the Real Property Assessment Division under the Department of Budget and Fiscal Services, with assessments based on fair market value as of January 1st each year.

The effective property tax rate in Honolulu County varies by property classification, with residential properties currently taxed at $3.50 per $1,000 of net taxable value for the tax year July 1, 2025 to June 30, 2026. This rate is applied after eligible exemptions are deducted from the assessed value. Property owners may qualify for various exemptions including the home exemption program, which can significantly reduce the tax burden for owner-occupied residential properties.

Supplemental Tax Bills

Honolulu County has implemented an "empty homes tax," which is a supplemental real property tax designed to address housing availability issues. This supplemental tax applies to residential properties that remain vacant for extended periods and is calculated as an additional assessment on top of the standard residential property tax rate. The empty homes tax is triggered when a residential property is determined to be unoccupied for a significant portion of the tax year, with specific criteria and exemptions outlined by the county.

Property owners subject to the empty homes tax will receive separate billing and must pay both the standard residential property tax and the supplemental empty homes tax. For example, a $800,000 vacant residential property would pay the standard residential tax of $2,800 annually ($800,000 ÷ 1,000 × $3.50) plus the additional empty homes tax assessment, significantly increasing the total tax liability for properties not serving as primary residences or long-term rentals.

Example Calculation

Example 1: $300,000 Residential Property

  • Assessed Value: $300,000
  • Home Exemption: -$120,000 (if qualified)
  • Net Taxable Value: $180,000
  • Annual Tax: $180,000 ÷ 1,000 × $3.50 = $630
  • Monthly Escrow: $52.50

Example 2: $600,000 Residential Property

  • Assessed Value: $600,000
  • Home Exemption: -$120,000 (if qualified)
  • Net Taxable Value: $480,000
  • Annual Tax: $480,000 ÷ 1,000 × $3.50 = $1,680
  • Monthly Escrow: $140

Example 3: $1,000,000 Residential Property

  • Assessed Value: $1,000,000
  • Home Exemption: -$120,000 (if qualified)
  • Net Taxable Value: $880,000
  • Annual Tax: $880,000 ÷ 1,000 × $3.50 = $3,080
  • Monthly Escrow: $256.67

Escrow & Property Taxes

Most mortgage lenders in Honolulu County require borrowers to maintain an escrow account for property tax payments, collecting monthly installments along with principal and interest payments. The lender holds these funds in escrow and makes property tax payments directly to the county on behalf of the homeowner. Property tax bills in Honolulu County are typically issued annually, and lenders must ensure adequate funds are available when payments are due.

Homeowners with escrowed property taxes should verify that their lender receives updated assessment information and tax rate changes to ensure proper payment amounts. The escrow account is analyzed annually, and adjustments may be made to monthly payments based on actual tax bills and account balance. For detailed payment procedures and options, including information for properties without escrow accounts, property owners can reference the official payment guide at https://www.honolulu.gov/rep/site/bfs/bfs_docs/RP_Tax_Payment.pdf.
