How to File in Hawaii
Review the assessment notice mailed by your county (real property tax is administered by counties).
File an appeal with the county Board of Review by the deadline (about January 15) with the filing fee.
Assemble comparable sales as of the October 1 assessment date.
Present evidence at the Board of Review hearing.
Appeal to the Tax Appeal Court if you disagree with the Board's decision.
Deadlines and ratios vary by county and change over time — always confirm with your local assessor. This is general information, not legal advice.
Are you actually over-assessed in Hawaii?
Check this property against recent comparable sales for $4.99. If the evidence says you have no case, you know that before you spend a filing deadline on it — and if it does, the same $4.99 is credited toward the full appeal packet.
A worked example in Hawaii
Say the assessor values your home at $400,000, but comparable sales show it is really worth $350,000 — a $50,000 over-assessment. Hawaii taxes the full market value, so the taxable amount drops by the same amount. At a typical effective rate of ~1.5%, that is about $750 back in your pocket every year until the value is corrected.
Illustration only. Your actual rate, exemptions, and savings depend on your county and taxing districts — run your own numbers.
Common grounds for a Hawaii appeal
Over-market valuation. Comparable sales of similar nearby homes closed below the value the assessor placed on yours.
Errors in the property record. The county has the wrong square footage, bedroom or bathroom count, lot size, or condition on file.
Unequal (non-uniform) assessment. Comparable properties in your area are assessed for less than yours, regardless of market value.
Physical or external problems. Deferred maintenance, functional issues, or an external nuisance depress what a buyer would pay.
Overvaluation · Incorrect classification · Denial of exemption
Don’t overlook exemptions
An appeal lowers your value, but exemptions cut your taxable base directly — and both stack. Most owners qualify for a homestead exemption on their primary residence, and many states add relief for owners over 65, veterans, and people with disabilities. Confirm you are enrolled with your Hawaii county assessor before filing — it is the fastest saving most people miss.
- Home Exemption $100,000–$160,000 assessed value
- Owner-occupied primary residence (varies by county)
- Senior Home Exemption Additional $20,000–$40,000
- Age 65+, owner-occupied
- Disability Exemption Varies by county
- Totally disabled
Who hears a Hawaii appeal

Each stage has its own deadline. Missing the first one usually closes the later ones for that tax year.
