You bought a piece of paradise. Smart move. Now you're thinking about selling, and a friend mentioned something about a withholding. Some percentage of your sales price being held back at closing. You're not sure if it applies to you, whether it's a tax you actually owe, or what happens to the money if it does get withheld.
Here's the short answer: if you're not a Hawaii resident and you're selling property on the Big Island, Hawaii will withhold 7.25% of your gross sales price at closing. Not your profit. Your sales price. On a million-dollar sale, that's $72,500 leaving your hands before you see a dollar. On a two-million-dollar sale, you're looking at $145,000 held by the state until you sort it out.
That's HARPTA. It's not a tax in the traditional sense. It's a prepayment mechanism the state uses to make sure non-residents actually file and pay their Hawaii capital gains taxes before they head back to the mainland. If you're also a foreign national rather than a U.S. citizen, the federal government has its own version called FIRPTA, and the two can stack on each other in ways that genuinely surprise people at closing.
I spent 35 years as a real estate attorney before I started selling property in Kona with Brenda Kuessner. I have seen these laws trip up plenty of otherwise well-prepared sellers. The good news is that neither HARPTA nor FIRPTA has to catch you off guard. But only if you know about them before you're sitting in escrow.
Key Takeaways
- HARPTA withholds 7.25% of your gross sales price at closing if you are not a Hawaii resident. Not your profit. Your full sales price.
- FIRPTA withholds 15% for foreign sellers and can apply on top of HARPTA in the same transaction.
- Neither is a final tax. Both are prepayment mechanisms, and you can recover overpaid amounts after you file your tax returns.
- You can apply to reduce or eliminate HARPTA withholding before closing by filing Form N-288B, but the deadline is 10 business days before the closing date.
- Filing early is the single most important thing a non-resident Kona seller can do to protect their proceeds.
The Problem: Most Non-Resident Sellers Don't Know This Is Coming
Kona attracts a specific kind of buyer. People who have visited the Big Island for years, fallen in love with it, and eventually bought a second home, a vacation rental, or an investment property. That's a lot of what we see on the Kohala coast and in the West Hawaii market generally.
When those same people sell, they often treat it like selling a home back on the mainland. You list it, you negotiate, you get into escrow, and a few weeks later you close. Simple enough.
Except Hawaii has a law that your California or Texas escrow experience did not prepare you for. The state knows that once you walk away from closing and fly home, collecting taxes from a non-resident is harder. So Hawaii collects first and sorts it out later. The 7.25% withholding goes to the Hawaii Department of Taxation before you see the rest of your proceeds. You then file a Hawaii tax return, report the actual gain, and either get a refund of what was over-withheld or pay any remaining balance.
The problem is not the law itself. That's actually a fairly reasonable approach from the state's perspective. The problem is timing. If you did not plan for this withholding before you listed the property, you may find yourself at closing with less cash than you expected, potentially creating problems if you needed those proceeds for a 1031 exchange, a new purchase, or anything else that is time-sensitive.
HARPTA: What It Actually Is
HARPTA stands for the Hawaii Real Property Tax Act. It applies when the seller of Hawaii real property is not a Hawaii resident at the time of closing.
The withholding rate is 7.25% of the gross sales price. Note again that this is the full sales price, not your gain. If you bought your Kona home for $800,000 and you're selling it for $1,200,000, the withholding is not calculated on your $400,000 gain. It's calculated on the $1,200,000 sale price. That's $87,000 withheld.
The buyer's escrow company is technically the withholding agent, meaning they are legally responsible for making sure the withholding happens correctly. In practice, the funds come out of your proceeds and get sent to the state.
Who counts as a non-resident? Anyone who is not a Hawaii resident for tax purposes at the time of sale. If you moved off the island six months ago and you're selling from the mainland, you're likely a non-resident even if you were a Hawaii resident when you bought the property. This catches a lot of people who have been in the process of relocating. If you haven't firmly established residency somewhere else, Hawaii may still consider you a non-resident.
Does HARPTA apply if you're selling at a loss? Technically yes, unless you file for an exemption. The state is not automatically aware that you lost money. You have to tell them, which requires filing Form N-288B before closing.
What about rental properties? If you've been operating the property as a rental, there's an additional wrinkle. Form N-288B has a section asking for your Hawaii General Excise Tax number. If you have not been filing and paying GET on your rental income, you may have to square that before the state will approve your withholding certificate. If your property is leasehold rather than fee simple, there are additional considerations worth understanding before you list. We cover those in our leasehold vs. fee simple guide.
FIRPTA: The Federal Layer
FIRPTA (the Foreign Investment in Real Property Tax Act) is the federal government's version of essentially the same concept. It applies to foreign sellers: non-resident aliens, foreign corporations, foreign trusts. If you are a U.S. citizen or a permanent resident (green card holder), FIRPTA does not apply to you.
The standard withholding rate under FIRPTA is 15% of the gross sales price. There are two exceptions worth knowing:
- If the buyer is purchasing the property for their own use as a primary residence and the sales price is $300,000 or less, no FIRPTA withholding is required.
- If the buyer is purchasing as a primary residence and the sales price is between $300,001 and $1,000,000, the withholding rate drops to 10%.
On Kona's luxury market, where median prices run well above $1,000,000 on the Kohala coast, the 10% exception rarely applies. Most transactions in our market will be subject to the full 15% if FIRPTA applies at all.
The stacking problem: A foreign seller of a Kona property is looking at both HARPTA and FIRPTA simultaneously. On a $2,000,000 sale, that's $145,000 withheld by Hawaii under HARPTA and $300,000 withheld by the IRS under FIRPTA. A combined $445,000 leaving your hands at closing. You'll get most or all of it back eventually, but the timing is the challenge.
How to Reduce or Eliminate the Withholding
This is where planning actually helps, and where an agent who understands the mechanics earns their commission.
For HARPTA: Form N-288B
Form N-288B is the Application for Withholding Certificate for Dispositions by Nonresident Persons of Hawaii Real Property Interest. Filing this form before closing is how you either reduce or eliminate the HARPTA withholding.
You can apply for a reduced withholding if your actual expected gain is less than what 7.25% of the sales price would cover. You can apply to eliminate the withholding entirely if you are selling at a loss or if the proceeds are insufficient to cover the withholding after paying selling costs and any mortgages.
The hard deadline is 10 business days before the closing date. Not calendar days. Business days. The state does not accept late submissions, and this is not negotiable. File early.
The form goes to the Hawaii Department of Taxation district office in the county where the closing is taking place. It must be mailed or hand-delivered. Fax is not accepted. It must have original signatures, not photocopies. If your partner or spouse is also on title, each non-resident seller needs a separate N-288B.
Once the state approves the certificate, the escrow company withholds the reduced (or zero) amount instead of the full 7.25%. If they have not received the approved certificate before closing, they will withhold the full amount regardless.
If you miss the N-288B window, your option is to file Form N-288C after closing. That is the Application for Tentative Refund of Withholding. It gets you a refund faster than waiting until you file your annual Hawaii tax return, but it is still slower than not having the money withheld in the first place.
For FIRPTA: Form 8288-B
The federal equivalent is IRS Form 8288-B. The process is similar. You apply before closing for a withholding certificate based on your actual expected tax liability. The IRS has approximately 90 days to process these, which is a meaningful constraint given how escrow timelines work.
If you submit Form 8288-B and the IRS has not responded by closing, the buyer still withholds the full 15% at closing but can delay sending the funds to the IRS for up to 20 days after the IRS makes its determination. If approved, only the reduced amount goes to the IRS and the rest comes back to you.
The Five Things to Do Before You List
Knowing the rules is useful. Doing these things early is what actually protects your proceeds.
1. Establish your residency status clearly before you list. Know whether you will be treated as a Hawaii resident or non-resident at the time of closing. If you are in the middle of relocating, understand that Hawaii's definition of residency for tax purposes is not the same as simply having moved. Talk to a Hawaii CPA or tax attorney about your specific situation before you sign a listing agreement.
2. Work with a qualified CPA or tax attorney before you close. I say this even though I was a transactional real estate attorney for 35 years: tax planning for HARPTA and FIRPTA requires someone who specializes in Hawaii tax law. Brenda and I can identify the issue and direct you to the right people, and we do. But filing your own N-288B without qualified guidance is a mistake I would not recommend.
3. Start the paperwork early. Much earlier than you think you need to. The 10-day HARPTA deadline and the 90-day FIRPTA processing window mean that waiting until escrow opens is already too late to optimize your outcome. The sellers who navigate this well are the ones who started thinking about it when they first considered listing.
4. Check your GET compliance if the property was a rental. If you have been collecting rental income and have not been filing Hawaii General Excise Tax returns, this is the time to find out what you owe. An unapproved N-288B due to GET issues is a common reason sellers end up with the full withholding at closing when they did not expect it.
5. Understand that a refund is not the same as not having the money withheld. The state will refund over-withheld amounts after you file your Hawaii tax return. The IRS will do the same under FIRPTA. But refunds take time. Sometimes months. If you have a 1031 exchange in play, a new purchase with a closing date, or any other reason you need those funds on a specific timeline, a delayed refund creates a real problem. The forms exist precisely to avoid that scenario.
Frequently Asked Questions
Does HARPTA apply if I lived in the house as my primary residence?
It depends on your residency status at the time of closing, not when you purchased. If you lived in the property as your primary residence for at least two of the five years before the sale, you may qualify for the federal capital gains exclusion, which affects your actual tax liability. But HARPTA withholding can still apply at closing unless you file Form N-288B. The key is that the withholding and the final tax calculation are two separate things. The withholding happens automatically unless you take steps to address it; the final tax is sorted out when you file your return.
What if I'm moving off the island before I close?
This is a common situation in the Kona market. Sellers who have relocated to the mainland while their property is listed are frequently treated as non-residents for HARPTA purposes even if they were Hawaii residents when they bought. Hawaii looks at your residency status at the time of closing. If you have moved and not yet established firm residency elsewhere, talk to a tax professional about your status. Do not assume you are exempt.
Can both HARPTA and FIRPTA apply to the same sale?
Yes, and it happens regularly on the Big Island with international buyers who eventually sell. HARPTA is a state withholding law and FIRPTA is federal. They are completely separate systems that do not offset each other. Each applies independently based on its own criteria. A foreign national selling a Kona property will typically have both withheld simultaneously.
Does it matter whether the property was a rental or a personal home?
It can, in a few ways. Rental properties trigger the GET compliance issue on Form N-288B, as discussed above. They may also affect your calculation of gain due to depreciation recapture, which changes the actual tax owed and therefore the optimal withholding certificate amount. This is another reason to work with a Hawaii CPA who handles real estate transactions, not just someone who files general returns.
How long does it take to get a refund if money was withheld?
Under HARPTA, if you file Form N-288C for a tentative refund, the state aims to process it faster than waiting for the annual tax return cycle, but timelines vary. Under FIRPTA, the IRS's processing of Form 8288-B applications takes approximately 90 days. Filing your annual tax returns (Hawaii N-15 for state, 1040-NR for foreign sellers at the federal level) is ultimately what finalizes the calculation and releases any remaining refund. Plan for this to take several months in a straightforward situation; more complex scenarios take longer.
The Bottom Line
HARPTA and FIRPTA are not designed to take money from sellers unfairly. They are withholding mechanisms. The state and federal government making sure you don't fly home with a capital gain and no intention of filing. The money comes back, often most or all of it, once you file the right returns.
What they are designed for, however, is collecting first and sorting it out later. That timeline works fine for the taxing authorities. It does not always work fine for sellers who needed their full proceeds at closing for another purpose.
The sellers who navigate this well are not smarter than the ones who get caught short. They just knew about it earlier. On a $1,500,000 Kona sale, the difference between filing Form N-288B on time and not filing it is potentially $108,750 sitting with the state instead of in your pocket at closing. That is real money on a real timeline, and it is entirely avoidable with enough lead time.
