Hawaii FIRPTA and Foreign-Buyer Tax: 15% Federal Withholding on Sellers

Foreign nationals selling Hawaii real estate encounter two separate withholding regimes that stack at closing. The federal Foreign Investment in Real Property Tax Act, known as FIRPTA, requires the buyer to hold back 15% of the gross sales price and remit it to the IRS. Hawaii layers its own withholding, HARPTA, on top at 7.25% of the amount realized.

The combined 22.25% figure often catches sellers by surprise, especially when equity gets tied up for months while paperwork moves through the IRS Ogden campus and the Hawaii Department of Taxation. Add General Excise Tax obligations on rental income earned before sale, and the closing statement gets complicated quickly.

This article walks through how the two withholdings interact, when Form 8288 must be filed, how a withholding certificate can reduce the upfront cash grab, and how prior rental use triggers GET filings that must be resolved before or alongside the sale. Every dollar figure below reflects rates published by the IRS, the Hawaii Department of Taxation, and county assessors as of 2026.

What FIRPTA Is and How the 15% Rule Works

Congress passed FIRPTA in 1980 to close a loophole that let foreign owners sell U.S. real property and repatriate the proceeds without filing a U.S. tax return. Before FIRPTA, tracking down a non-resident seller after closing was expensive and often futile. The fix shifted the collection burden to the buyer, who is physically present at closing and has strong incentive to comply.

The mechanism works through Internal Revenue Code section 1445. When a foreign person disposes of a U.S. real property interest, the buyer (called the transferee) must withhold a percentage of the amount realized and remit it to the IRS within 20 days of closing. The rate started at 10%, jumped to 15% on February 17, 2016 under the PATH Act, and has held at 15% since.

The buyer, not the seller, carries personal liability for missed withholding. That is why title companies and escrow agents scrutinize seller citizenship and residency status before releasing funds. A W-9 with a valid Social Security Number or ITIN, plus a signed FIRPTA affidavit confirming U.S. person status, protects the buyer from a 15% assessment plus penalties and interest.

Who counts as a foreign person

FIRPTA defines foreign person broadly: any individual who is not a U.S. citizen or resident alien, plus foreign corporations, foreign partnerships not electing domestic treatment, foreign trusts, and foreign estates. Green card holders count as U.S. persons. A visa holder passing the substantial presence test — 183 weighted days across three years — is also treated as a U.S. person for FIRPTA purposes.

Snowbirds who split time between Hawaii and Canada, Australia, or Japan sometimes fall on the wrong side of the substantial presence test. Days present in the current year count fully, one-third of the prior year, and one-sixth of the year before that. A Canadian retiree wintering in Kailua-Kona for several years may or may not clear the threshold; the calculation matters when the sale hits escrow.

Census demographic data suggests Hawaii has a higher share of non-resident and foreign property ownership than most states, driven by concentrated foreign investment in Oahu high-rises and Maui resort condos. That concentration explains why every escrow officer in Honolulu treats FIRPTA screening as a standard closing checklist item rather than an exception.

FIRPTA vs HARPTA: Two Withholdings, One Closing

HARPTA, codified at Hawaii Revised Statutes section 235-68, mirrors the federal rule but with two important differences. First, HARPTA applies to any non-Hawaii resident — a California LLC, a Nevada trust, or an Oregon retiree all trigger HARPTA even though those sellers are U.S. persons for federal purposes. Second, the state rate is 7.25%, up from a prior 5% floor.

The overlap for foreign sellers is total. A Japanese national selling a Waikiki condo faces both FIRPTA (15%) and HARPTA (7.25%), because the seller is simultaneously a foreign person under federal law and a non-Hawaii resident under state law. A New York citizen selling the same condo faces only HARPTA. A Honolulu resident with a Hawaii driver’s license and voter registration faces neither.

The paperwork diverges too. FIRPTA uses Form 8288 (transmittal) and Form 8288-A (seller statement). HARPTA uses Form N-288 as the transmittal and Form N-288A as the seller statement. The state’s standalone 7.25% withholding rule covers HARPTA mechanics in depth; the stacking math below is where the pain shows up on a closing statement.

Who owes what: a decision matrix

The Stacking Math on a Hawaii Sale

Concrete numbers make the impact obvious. Consider a Japanese owner selling a Kihei condo purchased in 2015 for $520,000, now closing at $985,000. The federal withholding pulls 15% of the gross $985,000 sales price — not 15% of the gain, not 15% of net proceeds — for $147,750 sent to the IRS. HARPTA takes 7.25% of $985,000 for another $71,412.50 sent to Honolulu.

Add Hawaii conveyance tax, which climbs on a sliding scale for higher-value sales, and the seller sees more than $220,000 of gross proceeds routed to tax authorities before the mortgage payoff clears. The county conveyance stamp rules layer another expense that hits the seller side on most residential contracts.

The problem is not the ultimate tax bill — foreign sellers often owe far less than 22.25% once basis and depreciation recapture are calculated. The problem is timing. Withholding is a prepayment, and the money does not come back until the IRS and Hawaii DOTAX process refund requests, which can take six to twelve months after year-end filings.

A withholding certificate application (covered below) is the pressure-release valve. Filed before closing with Form 8288-B, it asks the IRS to reduce the amount withheld to something closer to the actual estimated tax liability. Approved certificates can drop the withholding to zero when the sale generates a loss, or to a specific dollar figure when a modest gain exists.

Sample closing statement math

Filing Form 8288: The 20-Day Clock

Form 8288 is the IRS transmittal that reports FIRPTA withholding. It must reach the IRS by the 20th day after the date of transfer, meaning the closing date. The form goes to the IRS Ogden Service Center. A separate Form 8288-A is prepared for each foreign seller and is stamped by the IRS as proof the withholding was received. The stamped copy is what the seller later attaches to Form 1040-NR to claim credit.

Who actually files the form matters. Legally, the buyer is the withholding agent. In practice, escrow companies handle the paperwork and cut the check from closing proceeds. Escrow will not release the seller’s net until Form 8288 is filled out, signed by the buyer, and either mailed or delivered to the IRS with the withholding check attached.

Missing the 20-day deadline creates penalties on the buyer. Failure-to-file penalties run at 10% of the amount required to be withheld, plus interest from the due date. That is why buyer-side attorneys insist on aggressive escrow instructions when a foreign seller is involved — the buyer never sees the funds, but still catches the liability if paperwork goes sideways.

What Form 8288-A does for the seller

Form 8288-A serves as the seller’s receipt. It shows the amount withheld, identifies the seller by name and taxpayer identification number, and once IRS-stamped, functions as proof of prepayment. The seller attaches a stamped copy to the U.S. tax return filed for the year of sale — usually Form 1040-NR for individuals — and the withholding is credited dollar-for-dollar against actual tax owed.

The catch: the IRS does not always return the stamped 8288-A quickly. Processing can take four to six months, sometimes longer. Sellers who need the stamped copy to file a timely return often submit the return anyway with a copy of the unstamped 8288-A and the withholding check number, then follow up if the IRS questions the credit.

Cutting the Withholding with Form 8288-B

Form 8288-B is the withholding certificate application. It asks the IRS to reduce or eliminate the 15% FIRPTA withholding when the seller’s expected tax liability is lower than the amount that would otherwise be held back. Filed correctly and on time, it can free hundreds of thousands of dollars of equity that would otherwise sit at the IRS Ogden campus for months.

The form is short but requires supporting documentation: the sales contract, a settlement statement or estimated closing statement, evidence of the seller’s basis in the property (usually the original purchase HUD-1 or closing disclosure), depreciation schedules if the property was ever rented, and a calculation showing estimated federal tax on the sale.

Timing is everything. The application must be filed on or before the date of closing to trigger the deferral rule. Once the IRS receives the application, the buyer can hold the withholding in escrow instead of remitting it — pending IRS decision — provided a copy of the application acknowledgment is attached to the closing package.

The IRS aims to process certificate applications within 90 days. Real-world processing has varied; delays of 120 to 180 days are common when the IRS Ogden campus runs behind. The Hawaii equivalent, Form N-288B, follows a parallel path with the Hawaii Department of Taxation and can also be filed to reduce HARPTA to something closer to actual state liability.

When a certificate makes sense

• Sale generates a loss compared with adjusted basis (certificate can zero withholding).
• Gain is modest and 15% of gross far exceeds the actual federal tax bill.
• Seller has NOL carryovers or capital losses that offset the recognized gain.
• Installment sale where full amount realized is not received at closing.
• Like-kind exchange under section 1031 that qualifies for FIRPTA exemption.

When it does not

• Sale price is well above the property’s basis and depreciation was heavy.
• Seller is uncertain about basis records and cannot document adjusted cost.
• Closing date is inside 30 days and the application will not clear in time.
• Seller lacks a U.S. Taxpayer Identification Number and has not applied for one.

Rental History and General Excise Tax

Hawaii’s General Excise Tax is not a sales tax on the seller; it is a gross receipts tax that applies to nearly every business activity in the state, including rental of residential property. Foreign sellers who ever rented the Hawaii property — short-term, long-term, or seasonally — likely owe GET on that rental income and must clean up filings before or at closing.

The base GET rate is 4%. On Oahu, a 0.5% county surcharge pushes the effective rate to 4.5%, though landlords who pass the tax through to tenants use a visible rate of 4.712%. Maui, Kauai, and Hawaii County each have county surcharges that push their effective rates slightly above 4%.

The mechanics are described in detail in a separate GET explainer. The relevant point at sale: title companies now regularly request evidence that all GET returns have been filed and any tax paid before releasing seller proceeds. An unfiled GET account can hold up closing while the Hawaii Department of Taxation issues a tax clearance.

Short-term rental owners face additional exposure. Transient Accommodations Tax (TAT) at 10.25% state plus county surcharges applies to rentals of less than 180 days. Owners who advertised on Airbnb or Vrbo without registering for GET and TAT often carry three to five years of unpaid liability, penalties, and interest by the time a sale is contemplated.

Rental-related withholding stack on a foreign seller

Oahu owners who rented under 30 days after Bill 41 passed face an additional enforcement layer. The 30/90-day rental rule restricts what qualifies as legal transient accommodation, and unpermitted short-term rental history can complicate the disclosure package a foreign seller must provide to the buyer at closing. Coverage from Civil Beat tracks enforcement patterns city by city.

ITINs, W-8BEN, and Common Filing Traps

Every FIRPTA withholding must reference a Taxpayer Identification Number. For foreign individuals who do not qualify for a Social Security Number, that means an Individual Taxpayer Identification Number (ITIN) issued on Form W-7. Without one, the IRS cannot credit the withholding to the seller, and Form 8288-A cannot be properly filed.

ITIN processing runs six to eleven weeks in normal periods, longer during the January-through-April crush. Foreign sellers who wait until escrow opens to apply for an ITIN often find themselves closing without a number, with the withholding sitting in an IRS suspense account until the ITIN arrives. That delays refund recovery by months.

Certifying Acceptance Agents in Hawaii and on the mainland can authenticate passport documents for ITIN applications without the applicant mailing the original passport to Austin. That workaround is popular because sending a Japanese, Canadian, or European passport to Texas for eight weeks is a non-starter for most sellers.

Form W-8BEN, often confused with FIRPTA paperwork, is unrelated. W-8BEN establishes foreign status for U.S. tax withholding on portfolio income (dividends, interest, royalties). It does not exempt a foreign seller from FIRPTA. Escrow companies occasionally accept a W-8BEN as if it were a FIRPTA affidavit; that is a mistake and can leave the buyer exposed to withholding liability.

Where filings actually go

• Form 8288 and 8288-A: IRS Ogden campus, mailed with certified funds.
• Form 8288-B: IRS Ogden, filed before or at closing with supporting exhibits.
• Form W-7 (ITIN): IRS Austin, or through a Certifying Acceptance Agent.
• Form N-288 and N-288A: Hawaii DOTAX, filed within 20 days of transfer.
• Form N-288B (HARPTA reduction): Hawaii DOTAX, filed on or before closing.
• Form N-288C (fast HARPTA refund): filed after closing for expedited state refund.

The Refund Timeline After Closing

Getting the overpayment back is a two-track process, one for FIRPTA and one for HARPTA. Both refunds require filing a return for the tax year the sale occurred and claiming the withholding as a credit. Individual foreign sellers file Form 1040-NR for federal; the Hawaii equivalent is Form N-15, the non-resident state return.

The federal 1040-NR deadline is June 15 for foreign filers with no U.S. wages, or April 15 for those with U.S. wages. Extensions are available on Form 4868, but an extension of time to file is not an extension of time to pay. Any tax not covered by withholding accrues interest from the original due date.

Hawaii offers Form N-288C for foreign or non-resident sellers who want a HARPTA refund before the annual return is due. It is an expedited refund claim that the state tax department historically processes in three to six months. To qualify, the seller must show that HARPTA withheld exceeds actual Hawaii tax liability on the sale gain.

Practical timeline: closing in July, ITIN and 8288-A stamped copy back by December, federal 1040-NR filed the following June, refund check issued eight to twelve weeks after that. Total time from closing to federal refund often runs sixteen to twenty months. State refunds via N-288C move faster but still require patient cash-flow planning.

Refund tracking milestones

Exemptions, Edge Cases, and Estate Situations

Not every foreign-seller closing triggers full 15% withholding. FIRPTA carries a residence exception: if the buyer intends to use the property as a personal residence and the sales price is $300,000 or less, no FIRPTA withholding is required. A partial reduction to 10% applies when the sales price runs between $300,001 and $1,000,000 and the residence intent is present.

The residence-intent exemption requires a signed statement from the buyer confirming personal-use intent for the two 12-month periods following purchase. Investors buying to rent do not qualify. Buyers should keep documentation because the IRS can revoke the exemption retroactively if occupancy patterns contradict the affidavit.

Corporate sellers face different withholding math when they qualify as domestically controlled Qualified Investment Entities or when treaty relief applies. Some U.S. tax treaties reduce or eliminate FIRPTA on specific transactions, though the treaty override process is administratively cumbersome and rarely used for single-property sales.

Estate and inheritance transactions

Foreign nationals who inherited Hawaii property face additional complexity. Basis is generally the fair market value at date of death, which can eliminate most of the taxable gain when property is sold shortly after inheritance. Without a formal appraisal at date of death, the IRS may default to the decedent’s original basis, which often produces a large phantom gain.

Estate paperwork ties directly to sale readiness. A small-asset probate affidavit under HRS 560 may satisfy title requirements without full probate for estates under a threshold. Larger estates require Hawaii probate court action. Attorneys often coordinate probate closure with the sale timeline so title clears at the same moment FIRPTA and HARPTA paperwork moves.

Where the deceased owner used a transfer-on-death deed under HRS 527, the beneficiary can often close a sale without probate at all, though FIRPTA still applies if the beneficiary is a foreign person. That combination — probate avoided but FIRPTA still withheld — surprises heirs who assumed one solved the other.

Coordinating Escrow, Attorneys, and the CPA

The FIRPTA process pulls together three professionals: the escrow officer at closing, a U.S. tax attorney or enrolled agent who prepares Form 8288-B, and the CPA who will file the year-of-sale return. Foreign sellers who assemble this team 60 to 90 days before listing avoid the cash-trap that hits sellers who wait until an offer is signed.

Escrow officers in Hawaii see FIRPTA transactions regularly, especially on Oahu, Maui, and the Kona coast where foreign ownership is concentrated. They will prepare Form 8288 and cut the withholding check from closing proceeds. What they do not do: prepare Form 8288-B applications, calculate estimated tax liability, or advise on treaty positions. Those tasks require a licensed tax professional.

Attorney fees for a straightforward 8288-B application typically run $1,500 to $3,500. When the property was rented, prior GET filings must be reconstructed and cleared, which adds accounting fees. Complex estate or multi-owner situations push total professional fees to $6,000 or higher, but the recovered cash flow from a reduced withholding usually justifies the spend on any sale above $700,000. Real estate reporting from the Honolulu Star-Advertiser gives useful context on prevailing sale prices by island.

Documents to have ready before listing

• Original closing disclosure or HUD-1 showing purchase price and settlement costs.
• Records of capital improvements (roof, kitchen, additions) with receipts.
• Depreciation schedules if the property was ever rented.
• Prior GET returns (Form G-45 and G-49) if rental income was earned.
• TAT returns for short-term rental history since 2015.
• Trust or entity documents establishing ownership structure.
• Passport, visa, and prior 1040-NR filings if any exist.

Frequently asked questions

Does FIRPTA apply if the foreign seller has a green card?

No. Green card holders are treated as U.S. persons for FIRPTA purposes regardless of where they live. The seller signs a non-foreign affidavit with a valid Social Security Number, and the buyer withholds nothing at the federal level. HARPTA still applies if the green card holder does not reside in Hawaii, so a Los Angeles-based green card holder selling a Maui condo owes 7.25% state withholding.

Can the 15% withholding be waived if the sale loses money?

Yes, but only through a Form 8288-B withholding certificate application filed with the IRS. The seller must document adjusted basis, sale price, selling expenses, and any depreciation recapture. If the calculation shows no federal tax owed, the IRS can issue a certificate reducing withholding to zero. Application must be filed on or before closing to trigger deferred withholding treatment.

How long does it take to get FIRPTA money back?

From closing to federal refund typically runs 16 to 20 months. The seller waits for the stamped Form 8288-A (four to six months), files Form 1040-NR the following spring or summer, then waits eight to twelve weeks for the refund. Faster recovery requires a Form 8288-B certificate filed at closing, which prevents the overwithholding from happening in the first place.

Does HARPTA still apply if FIRPTA does not?

Yes. HARPTA depends only on Hawaii residency, not U.S. citizenship. A California CPA selling a Kauai vacation home owes 7.25% HARPTA even though FIRPTA does not apply. The state uses its own N-288B application to reduce withholding when actual state tax liability is lower than the 7.25% withholding, and Form N-288C for an expedited refund after the sale closes.

What happens to GET on rental income earned before the sale?

Unpaid General Excise Tax on prior rental income does not disappear at closing. Title companies now routinely request DOTAX tax clearance certificates before releasing seller proceeds, and unfiled GET returns can freeze escrow. Sellers with rental history should file back-year Forms G-45 and G-49, pay tax, penalties, and interest, and obtain clearance before closing to avoid last-minute delays.

Does the buyer face any personal risk?

Yes. The buyer is the withholding agent under section 1445 and carries personal liability if FIRPTA withholding is skipped when it should have been applied. Penalties equal 10% of the amount that should have been withheld plus interest. Buyers protect themselves by requiring a signed non-foreign affidavit from the seller with a valid Taxpayer Identification Number at closing.

Do treaty positions actually reduce FIRPTA in practice?

Rarely for single-property residential sales. Most U.S. income tax treaties preserve the source country’s right to tax real property gains, so treaty relief for FIRPTA is narrow. Cross-border pension funds and certain sovereign entities have specific exemptions. For an individual foreign seller closing a Maui condo, treaty analysis is usually not worth the professional fees compared with a straightforward Form 8288-B application.
