Hawaii property taxes for mainland sellers HARPTA guide by Julie Wettstein Realtor

What Taxes Do I Pay When Selling Property in Hawaii as a Mainland Owner?

May 01, 20263 min read

If you own property on theBig Island of Hawaiibut live on the mainland, one of the biggest concerns when selling is:

“What taxes am I going to owe?”

This is a smart question to ask early… because Hawaii has a few unique rules that can surprise sellers who aren’t familiar with them.

Here’s the simple breakdown.

(Quick note: I’ll explain how this works, but you should always confirm details with a CPA or tax professional.)

Julie Wettstein, Realtor RB-21086, helps mainland owners navigate the selling process on the Big Island so there are no surprises along the way.


The 3 Main Taxes Mainland Sellers Should Know

When you sell a property in Hawaii, there are typically three things to be aware of:

1. Capital Gains Tax (Federal + Possibly State)

This is the big one.

If your property has increased in value, you may owecapital gains taxon the profit.

This depends on:

  • How long you owned the property

  • Whether it was your primary residence or investment

  • Your overall income

If it wasnot your primary residence, you typically won’t qualify for the capital gains exclusion.


2. Hawaii State Taxes

Hawaii may also tax the gain from your sale.

Even if you live on the mainland, Hawaii can tax income generated from property located in the state.

This is why working with a tax professional familiar with Hawaii is important.


3. HARPTA (This Is the Big One for Mainland Sellers)

This is where most confusion comes in.

HARPTA = Hawaii Real Property Tax Act

If you arenot a Hawaii resident, the state requires a withholding at closing.

This is not necessarily a final tax… it’s more like a prepayment.

Typically:

  • A percentage of the sale price is withheld

  • This amount is sent to the state

  • You may get some of it back after filing your taxes

This applies to many mainland sellers and can impact how much you receive at closing.


What HARPTA Actually Means for You

Let’s simplify it.

When you sell:

  • A portion of your proceeds may be withheld

  • You don’t lose this money permanently

  • You reconcile it when you file your tax return

The exact amount depends on your situation.

This is why planning ahead matters.


Real Example

A mainland owner selling a Kona property expected to receive the full sale proceeds at closing.

Once we walked through HARPTA and estimated taxes:

  • They understood the temporary withholding

  • Planned for the difference in net proceeds

  • Avoided surprises at closing

That clarity made the process much smoother.


Common Mistakes Mainland Sellers Make

Not Knowing About HARPTA

This is the biggest one.

Many sellers are surprised at closing when funds are withheld.


Not Planning for Net Proceeds

Taxes affect how much you walk away with.

You want a clear estimate upfront.


Waiting Too Late to Talk to a Tax Professional

The earlier you understand your situation, the better decisions you can make.


How to Prepare Before You Sell

If you’re selling from the mainland, here’s what to do first:

  • Get a clear estimate of your home’s value

  • Review your potential capital gains

  • Understand HARPTA withholding

  • Talk with a CPA familiar with Hawaii

  • Estimate your net proceeds after all costs

This gives you a complete picture before you list.


FAQ

Do I have to pay HARPTA if I don’t live in Hawaii?

In many cases, yes. It depends on residency status and other factors.


Do I lose the money withheld by HARPTA?

Not necessarily. It’s usually reconciled when you file your taxes.


Are there exemptions or ways to reduce HARPTA?

Possibly. A tax professional can guide you based on your situation.


Is this different from capital gains tax?

Yes. HARPTA is a withholding. Capital gains is the actual tax on profit.


Next Step

If you’re a mainland owner thinking about selling your Big Island property, the best first step is understanding your numbers.

That includes:

  • Estimated sale price

  • Selling costs

  • Potential taxes

  • What you’ll actually walk away with

Once you have that, everything becomes much clearer.
