What you'll pay, at a glance

Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About Honolulu County, HI

Honolulu County’s effective property tax rate of 0.284% sits above Hawaii’s statewide median of 0.247%, placing it first among the state’s four counties for property taxation. Even so, that rate looks restrained next to the national median of 0.794%. On a median home value of $897,500, the owner pays roughly $2,553 a year in real-estate taxes. Households earning a median of $106,195, with per-capita income at $47,516, absorb that bill against some of the highest housing costs in the country. The signal here is twofold: within Hawaii, Honolulu — the county’s largest city — carries the heaviest property tax rate, yet measured against mainland norms, the county still taxes property at a comparatively gentle pace, a function of Hawaii’s distinctive land and assessment system rather than low home prices.

Frequently asked questions

What is the property tax rate in Honolulu County, HI?
The effective rate is 0.28% — meaning the median tax bill equals about 0.28% of the median home value.
How much are property taxes on a median home?
On the median home ($897,500), the estimated annual bill is about $2,553.
Is Honolulu County's rate high or low?
Compare it to the state median of 0.25% and the national average near 1.1%.
How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the Honolulu County assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the Honolulu County assessor within the local deadline, typically with comparable sales as evidence.
