HARPTA Explained: How to Avoid Unnecessary Tax Surprises When Selling Real Estate in Hawaii

🌴 Understanding HARPTA: What Kauai Property Sellers Should Know

If you’re selling real estate in Kauai and you’re not a Hawaii resident, you’ll want to understand HARPTA before closing.

What is HARPTA?

  • HARPTA stands for Hawaii Real Property Tax Act.
  • It’s a withholding tax required when non-residents sell Hawaii real estate.
  • HARPTA is not an additional tax, but rather a prepayment of any potential Hawaii state capital gains tax owed.

How Much is Withheld?

  • The standard withholding rate is 7.25% of the sales price, not the net gain.
  • Example: Selling your Kauai property for $1,000,000? The escrow company must withhold $72,500 unless you qualify for an exemption.

Who Does HARPTA Apply To?

  • Anyone who is not considered a Hawaii resident for tax purposes—even if you once lived in Hawaii or own multiple properties here.
  • This includes:
    • Mainland U.S. residents
    • Foreign investors
    • Hawaii residents who moved out and no longer file HI state tax returns

Are There Exemptions?

  • Yes, you may qualify for partial or full exemption if:
    • You are selling at a loss
    • You’re a Hawaii resident for tax purposes
    • The property was your principal residence
  • To claim exemption or reduction, sellers must file:
    • Form N-289: to disclose residency or exemption status
    • Form N-288C: to apply for a withholding reduction or waiver

How is HARPTA Collected?

  • The escrow company withholds the HARPTA amount at closing.
  • It is then submitted to the Hawaii Department of Taxation.

How Do You Get a Refund?

  • If too much was withheld, you must file a Hawaii state tax return (Form N-15) to request a refund.
  • Refunds typically take several months, so plan accordingly.

Why Does This Matter?

  • HARPTA can impact your net proceeds from the sale.
  • Failing to plan ahead could result in cash flow delays or surprise tax obligations.
