HARPTA Explained: What Non-Resident Sellers Need to Know About Hawaii’s Real Property Tax Act

When selling real estate in Hawaii, one of the most important—and often unexpected—closing costs for non-resident sellers is HARPTA, short for the Hawaii Real Property Tax Act. Understanding this withholding requirement can save sellers time, stress, and help them plan ahead for a smoother transaction.

What is HARPTA?

HARPTA requires that when a non-resident of Hawaii sells real property, the buyer must withhold 7.25% of the sales price and remit it to the Hawaii Department of Taxation.

This withholding is not an additional tax—it represents an estimate of the state capital gains tax that may be owed. The withheld amount acts as a prepayment until the seller files their Hawaii tax return and determines the actual liability.

By default, escrow will withhold and remit HARPTA unless the state provides a valid exemption certificate or waiver that has been approved prior to closing.

Who Handles & is Responsible for HARPTA Withholding?

Escrow: Under the standard Hawaii Association of Realtors purchase contract, escrow is required to withhold and remit HARPTA unless an exemption or waiver has been approved.
Seller: It is the seller’s responsibility to prove that an exemption applies by providing the buyer with a valid certificate of exemption or waiver before closing.
Buyer: Ultimately, the buyer is legally responsible for ensuring HARPTA is withheld and remitted on time if the seller is a non-resident.

Are There Exemptions From HARPTA?

Qualifications for an Exemption:

Principal Residence Exemption – If the property was used as a primary residence for at least 12 months.
Sale at a Loss – If the property is being sold for less than the seller’s purchase price.
1031 Exchange – If the transaction qualifies under federal or Hawaii law as a tax-deferred exchange
Early Refund Request – Sellers may apply for an early refund, as soon as a few weeks after Closing

Yes—certain situations may qualify a seller for an exemption or reduced withholding.

To pursue and take advantage of these exemptions, sellers must complete and submit the appropriate forms, such as Form N-288B, N-288C, or N-289, along with supporting documentation well before closing.

Why HARPTA Matters for Sellers

For non-resident sellers, HARPTA can significantly impact net proceeds at closing. For example, on a $1,000,000 sale, the withholding would be $72,500. While this is credited against actual taxes owed, sellers should plan ahead to avoid surprises and discuss potential exemptions with their tax advisor.
