Hawaii Island (Big Island) Property Tax Appeal Guide

I am not an attorney or a tax professional, but after 43 years on the Kohala Coast I have helped resort owners understand exactly what drives their assessments and what a realistic appeal looks like. This guide covers only the real property tax appeal for Hawaii County, the county on the Big Island of Hawaii. Use it to get oriented, then confirm the specifics with the county or a qualified advisor before you file.

Why Big Island owners rarely appeal these days

Here is the honest reality check most owners do not hear before they start researching an appeal: on the Big Island right now, the market has climbed so fast in recent years that the county's assessed values often trail current sales prices. When your assessment is already below what your property would realistically sell for, there is simply little reason to appeal, because you have nothing to bring the bill down against.

I understand that feels backwards next to the headline about tax bills going up. But a rising tax bill and a rising market are not the same thing. The county reassesses on its own cycle using its models and the sales it captures, and in a market running this hot, those models frequently lag the transactions happening on the ground. That lag works in your favor on the assessment side, even as your property statement, and your headline sense of "what it is worth," climbs with everything else.

For most of my clients, the bigger question is no longer "how do I get my assessment lower?" It is making sure their assessment keeps up with what their property is actually worth. When values are rising this high, an appeal is less often about cutting your bill and more often about accuracy, whether that means confirming the county's number is fair or, in some cases, recognizing that it has caught up to you. If your assessed value already sits comfortably below what your own comparable sales suggest, an appeal is probably not the right lever to pull, and I will tell you that plainly rather than encourage you to file and spend the time and deposit.

Why the Big Island reassesses property and why your value can jump

Hawaii County revalues real property on a regular assessment cycle. Your assessed value is the county's estimate of what your property would sell for, and the county updates those estimates using its building and land models, recent sales, and market conditions across the district.

When the market moves, or when a nearby comparable sale pushes the county's model higher, your assessed value can jump even if you have done nothing to your property. On the Kohala Coast, where much of the value sits in land, ocean views, and resort improvements, a change in comparable sales data can produce a large increase in a single cycle.

Here is the honest truth: an increase is not automatically an error. But it is also not automatically correct. The county's model is a starting point, not a final judgment, and it can miss the specific character of a resort or condo property. That is the gap an appeal is meant to close.

Check your assessed value and compare it to market value

Start by pulling your current assessed value from Hawaii County's real property tax records. Confirm the parcel (TMK) number, the land value, and the improvement value on your assessment notice so you know exactly what the county is charging you for.

In Hawaii County, an appeal can be based on the assessment exceeding the fair market value of your property, or on a lack of uniformity or inequality in assessment, meaning your property is assessed at a higher proportion of value than other similar properties. Both groundings require the same preparation: real, comparable numbers.

"Comparable" is the word that matters most here. A sale from a different resort, a different island district, or a different property type does not carry much weight. The stronger your comparables, the stronger your case.

The step-by-step appeal process

Here is how the filing actually works, start to finish:

1. Obtain your assessment notice and confirm the parcel (TMK) number, the land value, and the improvement value on it.
2. Gather your supporting evidence. Recent comparable sales of similar Big Island properties, an appraisal if you have one, photos, and any documented property condition issues that lower the value.
3. Complete the Notice of Appeal on Real Property Assessment form (often referenced as RP Form 19-91), filling in the parcel information and your grounds for appeal.
4. Pay the non-refundable deposit required for each appeal filed with the Tax Board of Review.
5. File with the Tax Board of Review before the deadline. Hand-deliver and have your form date-stamped, or mail it postmarked on or before April 9, to the Hawaii County Real Property Tax office. Keep a copy and proof of filing for your records.

What happens after you file

Once filed, the Tax Board of Review reviews your appeal against the county's records and your submitted evidence. The Board may request additional documentation, comparable sales, or clarification before it decides.

The Board issues a written decision on your appeal. If you disagree with the outcome, a further appeal may be possible, generally to the State Tax Appeal Court within a set window of the Board's decision. Timelines vary, so keep records of every filing, receipt, and correspondence, and confirm deadlines with the county as your appeal moves forward.

Tips for Kohala Coast resort and condo owners

If your property is at Hualalai, Mauna Kea, or Mauna Lani, the generic playbook is not enough. Resort properties carry much of their value in location, views, golf proximity, and improvements, all of which a county model can misprice relative to a stand-alone house in an inland subdivision.

• Use genuinely comparable resort sales. A residence at one resort, or a similar condo unit nearby, is the evidence that matters. Inland sales will not help you.
• Separate land value from improvement value. Review how the county split your notice. A land-value overstatement is a common and legitimate appeal point on the Kohala Coast.
• Capture property condition. Deferred maintenance, renovation needs, or condition issues that are not reflected in the assessed value should be documented with photos.
• Watch the bellwether sales. A handful of strong recent resort closings can push a whole district's model up. If those closings do not reflect your specific property, say so with data.

A note on what this guide is and is not

This is general information to help you understand the Hawaii County real property tax appeal process. It is not legal, accounting, or tax advice, and it does not create an attorney-client or advisor-client relationship.

Deadlines, forms, deposit amounts, and requirements can change, and every property is different. Before you act, confirm the current details directly with the Hawaii County Department of Finance, Real Property Tax division, or with a qualified attorney, CPA, or property tax advisor.
