🔒 Official Hawaii Property Tax Resources by County
How Hawaii Property Tax Works
Hawaii property tax is local. The State of Hawaii Department of Taxation handles state taxes like income and general excise tax, but real property tax is administered by the county where the property is located.
This means your payment site, assessment records, tax rates, home exemption amount, due dates, appeal process and office contact can change depending on whether the property is on Oahu, Maui, Big Island or Kauai.
| Island / Area | County Office System | Best Use |
|---|---|---|
| Oahu | City and County of Honolulu | Honolulu/Oahu property tax lookup, payment, exemptions and RPAD records. |
| Maui, Molokai, Lanai | County of Maui | Maui County property assessment search, tax rates, tax payment and relief programs. |
| Big Island | County of Hawaii | Hawaii County real property tax, payment, exemptions, appeals and tax code resources. |
| Kauai | County of Kauai | Kauai real property tax payment, assessment search, tax rates and exemptions. |
How to Look Up Hawaii Property Tax by Address, TMK or Parcel
The exact search field depends on the county. Hawaii property records often use a Tax Map Key, also called TMK, or a parcel identifier. Address search is useful, but parcel/TMK search is usually cleaner.
1
Identify the island and county first
This prevents wrong payment portal mistakes
Use Honolulu for Oahu, Maui County for Maui/Molokai/Lanai, Hawaii County for Big Island, and Kauai County for Kauai. Do not search or pay from a county system only because it appears first in Google.
2
Search by TMK or parcel if possible
More reliable than owner-name search
Tax Map Key or parcel number is usually the cleanest way to find a Hawaii property tax record. If you only have an address, use the county property search and then save the parcel/TMK for future payments, escrow, appeals and exemptions.
3
Confirm classification and exemption status
Hawaii rates depend heavily on use/class
Check whether the property is owner-occupied, residential, non-owner-occupied, hotel/resort, vacation rental, commercial, agricultural or another class. The same market value can create a very different bill depending on class and exemption status.
4
Review the tax year and installment
Most Hawaii property tax bills are paid in two parts
Before paying, confirm the tax year, first-half or second-half installment, due date, assessed value, exemption, tax rate, current balance and prior payment history.
How to Pay Hawaii Property Tax Online
Use your county’s official payment system. Hawaii counties may allow credit card, debit card, electronic check, personal bank account or county payment processor options, but fees and rules can be different.
Best first step
Open the county’s official real property tax payment page and search the invoice, TMK, parcel or address before paying.
Fee check
Review credit card, debit card and eCheck fees before checkout. A fee-free method in one county may not match another county.
| County | Official Payment Start | Payment Note |
|---|---|---|
| Honolulu / Oahu | Honolulu property tax payment | Use for Oahu properties under City and County of Honolulu. |
| Maui County | Maui electronic payment options | Maui says real property tax can be paid online or by phone by card, debit or electronic check. |
| Hawaii County | Hawaii County online payment | Only for Island of Hawaii parcels, not Oahu, Maui or Kauai. |
| Kauai County | Kauai property tax payment | Search invoice, add to cart, then pay by credit card or personal bank account. |
How to Calculate Hawaii Property Tax Online
Most Hawaii county rates are shown as dollars per $1,000 of net taxable assessed value. “Net taxable” usually means assessed value after approved exemptions or deductions.
1
Find assessed value
Use the correct county property record
Open your county property search and find the current assessed value. Confirm you are viewing the correct tax year or assessment year.
2
Subtract approved exemption
Only if it appears or is officially approved
Do not subtract a home exemption just because you live there. Confirm the exemption is filed, approved and reflected in your county record or bill.
3
Use the correct property class rate
Owner-occupied, residential and vacation rental can differ
Check the property class on the county record. Hawaii counties may use separate rates for homeowner, residential, non-owner-occupied, hotel/resort, vacation rental, commercial, industrial, agricultural and mixed-use properties.
| Example Item | Example Value | What It Means |
|---|---|---|
| Assessed value | $900,000 | County-assessed real property value. |
| Approved exemption | $120,000 | Only use if actually approved by your county. |
| Net taxable value | $780,000 | $900,000 minus $120,000. |
| Rate | $3.50 per $1,000 | Example county rate for the property class. |
| Estimate | $2,730 | $780,000 ÷ 1,000 × 3.50. |
Hawaii Property Tax Tips That Save Money and Avoid Wrong-Portal Mistakes
These practical checks help Hawaii homeowners and buyers avoid missed exemptions, wrong county payments, classification mistakes and weak appeal filings.
County first, payment second
Never pay until you confirm the county. Hawaii County’s payment system does not cover Oahu, Maui or Kauai parcels.
Classification matters
A vacation rental, non-owner-occupied home or hotel/resort property can have a very different rate than a homeowner class.
File exemption before deadline
Most counties require the home exemption claim before a stated deadline. Missing it can affect the next tax year.
Buyers should check future tax
The seller’s old home exemption or classification may not apply after sale. Estimate based on your future use.
Save TMK everywhere
TMK helps with property tax, permits, title records, assessment appeals and county support calls.
Appeal with evidence
Use comparable sales, condition photos, appraisal data and property-detail errors. General complaint rarely works.
Hawaii Property Tax Rates by County and Property Class
Hawaii property tax rates are not one statewide rate. Each county sets rates and property classifications. Some counties use tiers for high-value residential, non-owner-occupied or vacation rental properties.
County rate
The county council or county process sets rates for the fiscal year.
Property class
Owner-occupied and non-owner-occupied property can be taxed differently.
Exemption
Homeowner, senior, disability or income-based relief can reduce taxable value.
| County | Official Rate Resource | Practical Note |
|---|---|---|
| Honolulu / Oahu | Honolulu tax rates | Check homeowner, residential, hotel/resort, commercial and other Oahu classes. |
| Maui County | Maui property tax rates | Maui rates differ by class and may include tiered rates depending on classification. |
| Hawaii County | Hawaii County tax rates | The Real Property Tax Office notes rates are set by the County Council, not the office itself. |
| Kauai County | Kauai tax rates | Kauai FY 2025–26 rates include owner-occupied, non-owner-occupied, vacation rental, hotel/resort and other classes. |

Hawaii Home Exemption, Owner-Occupant Relief, Senior and Veteran Programs
Hawaii property tax exemptions vary by county. A homeowner exemption in Honolulu is not exactly the same as a Kauai or Hawaii County program. Always file with the county where the property is located.
Home exemption
Usually for owner-occupants who use the property as a principal residence and meet county requirements.
Income or senior relief
Some counties offer additional relief based on age, income or owner-occupant status.
Veteran / disability
Disabled veteran, blind, deaf or totally disabled exemptions may be available depending on county rules.
1
Check your county exemption deadline
Do not assume all Hawaii counties use the same deadline
Honolulu and Kauai commonly reference September 30 for home exemption filing. Other county programs may have their own rules or annual filing requirements. Use the exact county page before filing.
2
Confirm owner-occupant evidence
Hawaii counties may ask for residency proof
Common evidence can include Hawaii driver license or state ID, voter registration, Hawaii income tax filing, occupancy rules, ownership records and principal residence proof.
3
Report changes quickly
Renting, moving or changing use can affect exemption
If you move, rent the home, convert to vacation rental, change ownership or use part of the property for business, contact the county real property office. Exemption mistakes can create back taxes or penalties.
How to Appeal or Review a Hawaii Property Assessment
If you believe your assessed value, property class, exemption status or property details are wrong, use the appeal or assessment review process in the county where the property is located.
Value too high
Use comparable sales, appraisal support, market evidence and condition details.
Wrong classification
Check whether the county has classified the property as owner-occupied, residential, hotel/resort, vacation rental or another class.
Missing exemption
Check whether a home exemption, income relief, senior benefit, veteran or disability exemption was correctly applied.
Hawaii Property Tax Office Map and County Contact Starting Points
For statewide Hawaii property tax questions, there is no single real property tax payment counter. Start with the official county real property tax office for the island where the property is located.
Hawaii Property Tax Is County-Based
Use Honolulu for Oahu, Maui County for Maui/Molokai/Lanai, County of Hawaii for Big Island and County of Kauai for Kauai.
Honolulu / Oahu
Use Honolulu Real Property Assessment Division for assessment and exemption information, and Honolulu payment resources for Oahu tax bills.
Maui County
Use Maui Real Property Assessment Division, electronic payment options and tax-rate pages for Maui County properties.
Hawaii County
Use Hawaii County Real Property Tax Office for Big Island assessment, collection, exemptions, appeals and tax payment.
