HARPTA & FIRPTA for Koko Kai Sellers: What to Expect

Are you planning to sell a Koko Kai property and wondering how much cash you will actually take home at closing? If you live outside Hawaiʻi or you are a foreign seller for U.S. tax purposes, federal and state withholding can impact your net proceeds and your timeline. You want a smooth, on‑time closing with no surprises.

In this guide, you will learn how HARPTA and FIRPTA apply to Koko Kai sales, where the rules differ, how much buyers may need to withhold, and how to plan ahead so high‑value transactions do not stall at the finish line. Let’s dive in.

HARPTA vs. FIRPTA: Core differences

If you sell Hawaii real property, two separate withholding regimes may come into play.

• FIRPTA applies at the federal level when the seller is a foreign person for U.S. tax purposes.
• HARPTA applies at the state level when the seller is a nonresident of Hawaii. This can include U.S. citizens who live on the mainland and do not reside in Hawaiʻi.

Both can apply in the same Koko Kai transaction. The buyer is typically responsible for withholding and remitting the funds, and escrow will require the right documentation before closing.

Who is affected in Koko Kai

• You may be subject to HARPTA if you are not a Hawaii resident, even if you are a U.S. citizen.
• You may be subject to FIRPTA if you are a foreign person for U.S. tax purposes. This includes nonresident aliens, foreign corporations, and certain foreign entities.
• It is possible to be subject to both HARPTA and FIRPTA in the same sale. Without planning, that can create a large holdback at closing.

FIRPTA basics for foreign sellers

FIRPTA requires the buyer to withhold federal tax on the sale of U.S. real property interests when the seller is a foreign person. Withholding is a prepayment of tax, not the final tax due.

Rates and residence exception tiers

• General rule: the buyer withholds 15% of the amount realized, which is often the gross sales price.
• If the buyer acquires the property for use as a residence, FIRPTA may be reduced based on price tiers:
  • 0% withholding if the price is 300,000 dollars or less and the buyer certifies intended residence use.
  • 10% withholding if the price is more than 300,000 dollars but not more than 1,000,000 dollars and the buyer certifies intended residence use.
  • 15% withholding applies to other transactions.

On high‑value Koko Kai homes, the 15% standard can be a very large figure because it is calculated on the gross price, not your gain.

Forms and documentation

• If you are a U.S. person, you provide Form W‑9 to escrow.
• If you are a foreign person, you provide the appropriate Form W‑8 (for example W‑8BEN for individuals or W‑8BEN‑E for entities).
• The buyer files Form 8288 to remit funds to the IRS and provides Form 8288‑A as evidence of the amount withheld.
• To request reduced withholding, you or your representative apply for a withholding certificate using Form 8288‑B. If granted, it directs escrow to withhold less than the statutory amount.

Deadlines and liability

• The buyer must file Form 8288 and remit funds within 20 days after the transfer. This is a strict deadline.
• If the buyer fails to withhold when required, the buyer can be held liable for the tax that should have been withheld, plus penalties and interest.
• You still file your U.S. tax return after closing. Any overwithheld amount can be credited or refunded when you file.

HARPTA overview for nonresident sellers

Hawaii’s nonresident withholding is a separate state regime. Even if you are not a FIRPTA foreign person, you may still be a nonresident of Hawaii and subject to state withholding.

Key points for Koko Kai sellers:

• Applicability is based on Hawaii residency, not federal foreign status. U.S. citizens living outside Hawaiʻi can be subject to HARPTA.
• Hawaii’s calculation method and percentages differ from federal rules. The state may allow reduced withholding or a certificate of compliance. Because state rates, thresholds and forms can change, confirm the current requirements with the Hawaii Department of Taxation and your closing team.
• Like FIRPTA, Hawaii offers a process to request reduced withholding or an exemption, but the certificate must be obtained before closing if you plan to rely on it.

Why early planning matters in Koko Kai

In Koko Kai, values are often high. A standard FIRPTA holdback on a multi‑million‑dollar sale can pull a seven‑figure sum out of your proceeds at closing. HARPTA can add another layer of withholding. If reduced withholding certificates are not in place, escrow will typically withhold the statutory amounts and proceed.

Early planning gives you options, such as applying for a federal withholding certificate, pursuing a Hawaii certificate, or arranging an escrow holdback or surety bond while certificates are pending.

A practical timeline that works

Use this simple timeline and work backward from your target close date.

60–120+ days before closing

• Determine your federal and Hawaii residency or foreign status and ensure you have a valid TIN or ITIN.
• Engage a tax advisor familiar with FIRPTA and HARPTA, plus a local real estate attorney or closing agent.
• If you are nonresident or foreign, decide whether to apply for a federal withholding certificate using Form 8288‑B and a Hawaii certificate for reduced state withholding.

30–60 days before closing

• Submit Form 8288‑B to the IRS if you need reduced federal withholding. Processing often takes several weeks or longer, so start early.
• Submit the Hawaii withholding certificate application per current state procedures.
• Provide escrow with your completed W‑9 or W‑8 and all requested seller documentation.
• If certificates may not arrive before closing, negotiate escrow holdbacks, indemnities, or a bond arrangement to manage risk while allowing the timeline to hold.

Closing and 0–20 days after transfer

• If statutory withholding applies and no certificate was issued, the buyer must withhold and file Form 8288 with the IRS within 20 days of transfer.
• Ensure state withholding funds and forms are remitted within Hawaii’s deadline. Confirm the current state timeline with your closing agent.

Post‑closing

• File your U.S. and Hawaii tax returns to report the sale. You can claim credits for amounts withheld. If more was withheld than tax due, you may receive a refund after filing.

What buyers, sellers, and escrow should do

A coordinated team prevents delays. Here is what each party typically handles in a Koko Kai closing.

Sellers

• Provide W‑9 or the appropriate W‑8, plus your TIN, ITIN, or EIN.
• Decide early whether to pursue reduced withholding certificates at the federal and state levels and begin the applications.
• Coordinate with escrow on indemnities, holdbacks, or bonds if certificates are pending.
• Plan your post‑closing filings so you can recover any overwithheld amounts promptly.

Buyers (transferees)

• Verify the seller’s status and collect the W‑9 or W‑8.
• Confirm FIRPTA responsibilities and deadlines. If withholding is required, file Form 8288 and remit within 20 days of the transfer.
• Confirm HARPTA obligations, state forms, and remittance deadlines with the closing agent or local counsel.
• If relying on a withholding certificate, ensure the certificate is issued and delivered to escrow prior to closing or use a protective holdback.

Escrow and title

• Collect seller tax documentation and coordinate all federal and state withholding filings with the parties.
• Confirm whether Form 8288 will be filed and funds remitted on time if withholding applies.
• Track the issuance of federal and state withholding certificates and reflect them in closing instructions.

Common Koko Kai scenarios

• Mainland U.S. seller, nonresident of Hawaii: HARPTA generally applies, even if FIRPTA does not. State withholding planning is key.
• Foreign seller for U.S. tax purposes: FIRPTA applies, and HARPTA may also apply if you are not a Hawaii resident. Dual withholding is common unless certificates reduce it.
• Buyer intends to use as a residence: FIRPTA tiers may reduce the federal rate based on price. The buyer must certify intended use truthfully. This does not change HARPTA by itself.

Ways to reduce or manage withholding

You have several tools to lessen cash impact while staying compliant.

• Apply for an IRS withholding certificate using Form 8288‑B if your expected gain or tax is much lower than the statutory holdback. Submit well in advance.
• Apply for a Hawaii withholding certificate or waiver per the Hawaii Department of Taxation process. Confirm current requirements and timing.
• Use an escrow holdback or a surety bond to bridge timing if a certificate decision is pending near closing.
• If the buyer will use the home as a residence, confirm whether FIRPTA’s residence tiers apply to your transaction.

Certificates take time. Starting applications 60 to 120 days before closing can make the difference between an on‑time closing and last‑minute scrambling.

After the sale: getting your money back

Withholding is not the final tax. It is a prepayment that sits as a credit with the IRS and the State of Hawaii.

• File your U.S. federal income tax return and your Hawaii return to report the sale and compute the actual tax due.
• Use the Forms 8288‑A and your state documentation to claim credits for the amounts withheld.
• If the withholding exceeded your tax, you can typically receive a refund after your returns are processed.

Key takeaways for Koko Kai sellers

• HARPTA and FIRPTA are separate. You can be subject to one or both, depending on your residency and tax status.
• FIRPTA withholding is usually 15% of the gross price unless a residence exception applies or you have an IRS certificate. That can be a large number on a Koko Kai sale.
• Hawaii’s rules differ in scope, percentages, and forms. Confirm current state requirements with your closing team.
• Start early. Get status clarity, engage tax counsel, and submit certificate applications well ahead of closing to avoid avoidable holdbacks and delays.
