Hawaii has the lowest effective property tax rate in the nation at approximately 0.27% — compared to the national average of 1.02%. That sounds like a bargain until you remember that Oʻahu's median single-family home costs $1.2 million. Even at a low rate, the actual dollar amount adds up.
But here is what makes Oʻahu's property tax system genuinely interesting: the gap between owner-occupied and investment property tax rates is enormous. An owner-occupied home pays $3.50 per $1,000 of assessed value. A non-owner-occupied investment property pays $4.00 on the first million and $11.40 above that — more than three times the owner-occupied rate. This is not an accident. Honolulu actively incentivizes homeownership over investment speculation through the tax code.
If you own or are buying on Oʻahu, understanding the homeowner exemption, the tax classifications, and the deadlines can save you thousands of dollars every year.

Every Tax Classification on Oʻahu (FY 2025–2026)
Oʻahu assigns properties to one of several classifications, each with a different tax rate. The classification depends on how the property is used, not what it looks like.
| Classification | Rate per $1,000 | Who Pays This |
|---|---|---|
| **Residential A** — Tier 1 (first $1,000,000) | **$4.00** | Non-owner-occupied homes, no exemption |
| **Residential A** — Tier 2 (above $1,000,000) | **$11.40** | Same — investment/second homes above $1M |
| **Commercial** | **$12.40** | Office, retail, mixed-use |
| **Industrial** | **$12.40** | Warehouses, manufacturing |
| **Agricultural** | **$5.70** | Active agricultural use |
| **Vacant Agricultural** | **$8.50** | Ag-zoned land not actively farmed |
| **Preservation** | **$5.70** | Conservation-zoned land |
| **Hotel & Resort** | **$13.90** | Hotels, resorts |
| **Bed & Breakfast Home** | **$6.50** | Owner-occupied, legally permitted B&B |
| **Transient Vacation** — Tier 1 (first $800,000) | **$9.00** | Short-term vacation rentals |
| **Transient Vacation** — Tier 2 (above $800,000) | **$11.50** | Same — above $800K assessed value |
(Source: City & County of Honolulu Real Property Assessment Division, FY 2025–2026 Tax Rates)
The system is designed to reward people who live in their homes and penalize absentee investors and vacation rentals. A $1.5 million home occupied by the owner pays $4,830/year in property tax. The same $1.5 million home used as a rental pays $9,700/year — more than double. It is intentional, and we always make sure investors factor it into their projections.

Tax Examples: What You Actually Pay
Owner-Occupied (Residential, $3.50 rate, under 65 exemption)
| Home Value | Exemption | Taxable Value | Annual Tax | Monthly |
|---|---|---|---|---|
| **$500,000** | $120,000 | $380,000 | **$1,330** | $111 |

| **$1,500,000** | $120,000 | $1,380,000 | **$4,830** | $403 |
Owner-Occupied (65+, $160,000 exemption)
| Home Value | Exemption | Taxable Value | Annual Tax | Monthly |
|---|---|---|---|---|
| **$800,000** | $160,000 | $640,000 | **$2,240** | $187 |
| **$1,000,000** | $160,000 | $840,000 | **$2,940** | $245 |
Non-Owner-Occupied (Residential A, tiered rate, NO exemption)
| Home Value | Tier 1 ($4.00 on first $1M) | Tier 2 ($11.40 above $1M) | Annual Tax | Monthly |
|---|---|---|---|---|
| **$500,000** | $2,000 | — | **$2,000** | $167 |
| **$800,000** | $3,200 | — | **$3,200** | $267 |
| **$1,000,000** | $4,000 | — | **$4,000** | $333 |
| **$1,500,000** | $4,000 | $5,700 | **$9,700** | $808 |
The difference is dramatic. A $1.5M home costs $4,830/year if you live in it and $9,700/year if you do not — a difference of nearly $5,000 annually. Factor this into your investment property analysis.

How to Appeal Your Assessment
If you believe your property is assessed above market value, you can appeal.
| Step | Detail |
|---|---|
| **Notice mailed** | By December 15 |
| **Appeal deadline** | January 15 |
| **Appeal form** | BFS-RPA-M-8-12 |
| **Filing fee** | $50 per appeal |
| **Grounds for appeal** | Assessment exceeds market value by >10%, lack of uniformity, wrongful denial of exemption, illegality |
| **Burden of proof** | On the taxpayer — the assessor's value is presumed correct |
(Source: RPAD Appeals Information)
Tip: The strongest appeals come with 3–5 comparable sales within the past year that support a lower value. Simply arguing that your home "is not worth that much" without data will not succeed. Consider hiring a real estate appraiser if the potential savings justify the $500–$1,000 appraisal fee.
Upcoming Changes (2027)
Two bills signed into law will increase homeowner exemptions starting July 1, 2027 (FY 2028):
| Bill | Current Exemption | New Exemption | Estimated Annual Savings |
|---|---|---|---|
| **Bill 50** (under 65) | $120,000 | **$140,000** | ~$70/year |
| **Bill 49** (65+) | $160,000 | **$180,000** | ~$70/year |
(Source: Locations Hawaii, Grassroot Institute)
The savings are modest ($70/year), but they signal the City's continued commitment to tax relief for owner-occupants.
How Oʻahu Compares to the Mainland
| Metric | Hawaii | National Average |
|---|---|---|
| **Effective property tax rate** | ~0.27% | ~1.02% |
| **Median annual property tax** | ~$2,239 | ~$3,119 |
| **Median home value** | ~$839,100 | ~$318,000 |
(Sources: SmartAsset, Rocket Mortgage)
Hawaii homeowners pay less in property taxes as a percentage of home value than any other state. But because home values are so high, the dollar amounts are still meaningful. A $1M Oʻahu home at 0.31% effective rate pays $3,080 — which is comparable to what a $300K home in Texas pays at 1.0% effective rate.
What This Means for Buyers
File your homeowner exemption immediately after closing — do not wait until next year. The September 30 deadline applies to the following tax year, so the sooner you file, the sooner you start saving $420–$560/year. If you are buying a condo, ask the seller whether the property is currently classified as Residential (owner-occupied) or Residential A (investment) — the tax rate difference is substantial and affects your carrying costs. For overall buying guidance, see our First-Time Home Buyer Guide and Closing Costs Guide.
What This Means for Sellers
Buyers will ask about your property's current tax classification and annual tax bill. Have this information ready — it is on your assessment notice and available online at realproperty.honolulu.gov. If your property is currently classified as Residential A (because you moved out and rented it), be transparent about the higher rate. The buyer who plans to occupy the home will switch to the lower Residential rate after filing their own exemption. See our selling guide for more.
Frequently Asked Questions
Do I lose the homeowner exemption if I rent out a room?
No — as long as you continue to occupy the property as your primary residence for 270+ days per year, renting a room does not disqualify your homeowner exemption. However, if you move out entirely and rent the whole property, it will be reclassified to Residential A and taxed at the higher rate. See our House Hacking Guide for how to rent while maintaining owner-occupied status.
Can I get the homeowner exemption on a condo?
Yes. Condos are eligible for the homeowner exemption under the same rules as single-family homes — you must own and occupy the unit as your primary residence for 270+ days per year. The exemption reduces your assessed value by $120,000 (under 65) or $160,000 (65+), which reduces the taxable portion used to calculate your property tax.
How often are property values reassessed?
Every year. The City assesses all Oʻahu properties as of October 1, using comparable sales through June 30. Assessment notices are mailed by December 15. If you believe the new assessment is too high, you have until January 15 to appeal.
What happens if I hold my home in an LLC?
You lose the homeowner exemption. Properties held in an LLC cannot receive the exemption, which means you will be classified as Residential A and pay the higher rate. This is important for investors who want to hold properties in an entity — the tax cost of losing the exemption ($420–$5,000+/year depending on value) may outweigh the liability protection benefits of the LLC.
Is the homeowner exemption automatic?
No. You must apply by filing form BFS-RPA-E-8-10.3 at the Real Property Assessment Division, online at realproperty.honolulu.gov, or at any satellite city hall. The deadline is September 30. Once filed, you do not need to reapply unless you move to a different property.
