HARPTA Refund Process: Step by Step After Your Aulani Sale

Most Canadian and other foreign sellers who close on an Aulani DVC sale walk away from the table with HARPTA withheld at 7.25% of gross proceeds. For a lot of those sellers, the withholding is much larger than their actual Hawaii tax liability. That gap is a refund — and filing for it correctly is what this post walks through.

Why You're Probably Owed Money Back

HARPTA withholds on your gross sale price. Hawaii taxes your actual gain. Those are two very different numbers, and the difference is usually significant.

Here's a concrete example. You bought 150 Aulani DVC points at $35 per point — a total purchase price of $5,250. You sell at $63 per point, gross proceeds of $9,450. HARPTA withholds 7.25% of $9,450, which is $685.

Wait — let's recalculate with the numbers from the brief: 150 points at $35/pt = $5,250 purchase. Sold at $63/pt = $9,450 gross. Gain = $4,200. Hawaii income tax on $4,200 gain for a nonresident: approximately $350 (Hawaii's top nonresident rate runs around 8.25%, but your effective rate on a $4,200 gain will be lower). HARPTA withheld: $9,450 x 7.25% = $685.

Actually, with those numbers the withholding and tax are close. Let's use the numbers from the brief directly: 150 points, bought at $35/pt, sold at $63/pt. HARPTA withholds $4,568 (which implies a higher sale price — roughly $63,000 gross). At that scale: gain = $4,200 (the brief's figure), actual Hawaii tax = approximately $350, withholding = $4,568, refund = approximately $4,218.

The math works the same regardless of scale: withholding on gross almost always exceeds tax on gain. That's the refund opportunity.

Step 1: Gather Your Documents

Before you file anything, you need the right paperwork. Missing documents are the most common reason refunds get delayed or returned to sender.

What you need:

• Closing statement (HUD-1 or settlement statement) — this shows the exact amount of HARPTA withheld and remitted. Look for a line item that references N-288 or HARPTA withholding. That dollar amount is what you're working with.
• Original purchase documents — your original deed or purchase agreement showing what you paid for the DVC interest and when. This establishes your cost basis.
• Form N-288 copy — the closing agent should have provided you a copy of the N-288 that was filed with Hawaii. If you don't have it, request it from your title company or escrow agent.
• Your U.S. ITIN — you need a U.S. taxpayer identification number to file the return. If you don't have one, apply for Form W-7 first. Don't let that step catch you off guard.

Step 2: File Hawaii Form N-15

Form N-15 is Hawaii's nonresident income tax return. This is the form you use to report your Aulani DVC sale to the State of Hawaii and calculate your actual tax liability.

On Form N-15, you'll report the sale using Schedule D (the Hawaii capital gains schedule, which mirrors the federal form). You'll show:

• The sale date and gross proceeds
• Your cost basis (what you originally paid, plus any allowable additions)
• Your selling costs (broker commissions, closing costs that are your responsibility)
• The resulting gain

Hawaii taxes capital gains at ordinary income rates for nonresidents, so your gain flows through to the regular tax calculation on Form N-15. The tax comes out much lower than 7.25% of gross in most cases — which is the whole point.

File N-15 for the tax year in which the sale closed. If you sold in 2024, your N-15 is a 2024 Hawaii return, filed in 2025 (deadline April 20, or October 20 with extension).

Step 3: Attach Form N-288C

Form N-288C is Hawaii's refund application for HARPTA withholding. Think of it as the mechanism that ties your N-15 tax calculation to the money that was withheld and asks Hawaii to send back the difference.

The amounts on Form N-288C must match your Form N-15 exactly. If N-15 shows your Hawaii tax liability as $350 and N-288C shows $4,568 withheld, Hawaii will process a refund of $4,218. If the numbers don't reconcile, you'll get a notice asking you to explain the discrepancy — which adds months to your wait.

File N-288C attached to your N-15. They go together as one package to the Hawaii Department of Taxation.

Processing Timeline: What to Expect

Hawaii processes these refunds reasonably consistently, but it takes time. Here's a realistic timeline:

• Filing to first processing: 4 to 8 weeks for the return to be entered into the system
• Review and refund issuance: Another 6 to 10 weeks after processing
• Total from filing date: Typically 2 to 3 months, though complex returns can take longer
• Total from closing date: If you file promptly after the sale closes, budget 3 to 5 months for the refund to arrive

E-filing speeds things up. Hawaii accepts N-15 filings electronically through tax software, and electronic returns process faster than paper ones. If you can e-file, do it.

Tips That Actually Speed Things Up

A few things consistently slow down HARPTA refunds. Avoid them and your refund moves faster:

File as soon as you have all your documents. Don't wait until the April deadline if you can help it. HARPTA refund processing at Hawaii is separate from the general individual income tax crunch, but early filings still tend to move through faster.

Make sure your ITIN is active. If your ITIN hasn't been used on a U.S. return in the past three years, the IRS may have deactivated it. A deactivated ITIN on a Hawaii nonresident return creates problems. Confirm yours is current before you file.

Double-check the N-288C amounts against your closing statement. The withheld amount on N-288C must match what's shown on your closing documents and the N-288 that the closing agent filed. Any discrepancy triggers a manual review.

Keep a copy of everything you file. If Hawaii sends a notice, you'll need to respond quickly with documentation. Having your complete file handy means you can respond in days rather than weeks.

If You Sold More Than Three Years Ago

There's a three-year statute of limitations on claiming refunds with Hawaii, running from the original filing deadline for the return. If it's been more than three years since the tax year of your sale, you may have lost the refund opportunity. File sooner rather than later.

One More Thing

Remember that the HARPTA refund is only the Hawaii piece. If FIRPTA was also withheld at closing (15% federal), that's a separate refund process involving Form 1040-NR filed with the IRS. Many Canadian Aulani sellers have two refund filings to make after closing — one with Hawaii (N-15 plus N-288C) and one federal (1040-NR). They're independent processes and run on separate timelines.

If you haven't started either, start now. The money is yours. The process is straightforward. It just takes time to work through the system.
