Selling Aulani DVC from Canada: HARPTA and Tax Treaty Considerations

If you're a Canadian citizen selling your Aulani DVC ownership, the closing statement is going to show two withholding line items that can feel like a gut punch. One from Hawaii. One from the federal government. Together, they can hold back more than 22% of your entire sale price at closing — not your profit, your gross sale price. Understanding why this happens and what you can do about it before closing is worth real money.

Two Withholding Requirements, One Sale

When a non-U.S. person sells real property located in the United States, federal law requires the buyer (or their closing agent) to withhold a portion of the sale price and send it to the IRS. This is FIRPTA — the Foreign Investment in Real Property Tax Act — and for most foreign sellers, the rate is 15% of gross proceeds.

Hawaii has its own parallel system called HARPTA (Hawaii Real Property Tax Act), which works the same way at the state level. For foreign sellers, Hawaii withholds 7.25% of the gross sale price.

For a Canadian selling Aulani DVC, both apply. That's a combined 22.25% withheld at closing. On an $8,000 sale, that's $1,780 held back before you see a dime.

A Real Numbers Example

Let's say you own 200 Aulani points and you sell at $40 per point. Your gross proceeds are $8,000.

• FIRPTA withholding (15%): $1,200
• HARPTA withholding (7.25%): $580
• Total withheld at closing: $1,780

Now let's say you originally bought those points at $35 per point, so your purchase price was $7,000. Your actual gain on the sale is $1,000.

Your real U.S. federal tax on a $1,000 capital gain might be $150 to $200, depending on your tax situation. Hawaii's tax on that gain might be another $80 to $110. So your total actual tax bill on this transaction is somewhere around $250 to $310.

But $1,780 was withheld. The difference — potentially $1,400 to $1,500 — is eventually refundable. The withholding system is a deposit, not a final tax.

Why Withholding Is on Gross, Not Gain

Both FIRPTA and HARPTA are withholding mechanisms, not tax assessments. The IRS and the State of Hawaii have no way to know your actual gain at the moment of closing. They don't know what you paid, what improvements you made, or what your deductible selling costs are. So they withhold a percentage of gross proceeds and let you sort out the actual tax liability later through your return.

This is exactly why most Canadian Aulani sellers end up owed a refund — because the withholding vastly exceeds the actual tax on their gain.

The US-Canada Tax Treaty: It Helps, But It Doesn't Eliminate Withholding

Canada and the United States have an income tax treaty that prevents double taxation. If you pay U.S. tax on a gain, Canada generally gives you a foreign tax credit against your Canadian tax liability for the same income. You're not taxed twice on the same profit.

What the treaty does NOT do is eliminate the U.S. withholding requirement at closing. The withholding still happens. The treaty benefit comes when you file your Canadian return — you credit the U.S. tax you actually paid against what you owe Canada. If you overpaid U.S. tax (which is common because of the withholding), you file for a refund in the U.S., and then you report the net U.S. tax paid to Canada.

In practice: get your U.S. withholding sorted out first, then deal with your Canadian return second. The treaty protects you from paying full tax to both countries, but it works through the annual return process, not at the closing table.

The Pre-Sale Reduction Strategy

Here's where you can save significant money — but only if you act before closing.

Both the IRS and the State of Hawaii allow foreign sellers to apply for a reduced withholding certificate before the sale closes. The idea is straightforward: you submit documentation showing your actual expected gain and tax liability, and the agency authorizes the closing agent to withhold only the estimated actual tax rather than the statutory percentage.

For FIRPTA, the form is Form 8288-B (Withholding Certificate Application). You file it with the IRS before or at the time of closing. The IRS issues a withholding certificate that reduces the amount withheld to your actual estimated tax liability.

For HARPTA, the form is Form N-288A (Statement of Withholding on Dispositions by Nonresident Persons of Hawaii Real Property Interests). Hawaii reviews your estimated gain and, if your actual tax will be less than 7.25% of gross, can authorize a reduced withholding.

If you file these applications and get approval before closing, the difference can be dramatic. Instead of $1,780 withheld on an $8,000 sale, you might have $300 to $400 withheld — an amount that actually approximates your real tax liability.

What Happens If You Don't File in Advance

If you close without filing for reduced withholding, the full 22.25% gets withheld by the closing agent and remitted to the IRS and State of Hawaii. You don't lose that money permanently, but you do have to wait to get it back.

After the sale, you'd file a U.S. federal non-resident return (Form 1040-NR) reporting the actual gain and crediting the amount withheld. If the withholding exceeds your actual tax, the IRS sends you a refund. For Hawaii, you'd file Form N-15 (Hawaii Non-Resident Return) and attach Form N-288C to request the state refund.

Processing times vary, but plan on 3 to 6 months minimum. Paper returns take longer. If you e-file, it tends to move faster. Either way, you're waiting months for money that was yours to begin with.

What You Need to File the Pre-Sale Applications

To file Form 8288-B and Form N-288A, you'll generally need:

• Your U.S. Individual Taxpayer Identification Number (ITIN) — if you don't have one, apply for Form W-7 first, which adds time
• A copy of your original purchase agreement showing what you paid
• The sale contract showing the agreed price
• A calculation of estimated gain and estimated U.S. tax liability

The ITIN piece is critical. If you don't have a U.S. ITIN, you need to apply for one (Form W-7) before you can file either withholding certificate application. ITIN processing can take 6 to 11 weeks, so if your closing date is approaching, start this process immediately.

Next Steps

If you have a firm closing date, the time to act is now. Here's the sequence that makes sense:

1. Confirm you have a U.S. ITIN. If not, file Form W-7 first.
2. Gather your original purchase documents and your sale contract.
3. File Form 8288-B with the IRS and Form N-288A with Hawaii as far in advance of closing as possible.
4. Notify your closing agent that withholding certificate applications are pending — they can hold on full withholding while applications are under review, within IRS/Hawaii rules.
5. After closing, file your U.S. Form 1040-NR and Hawaii Form N-15 to reconcile any remaining withholding against your actual tax, and claim any refund owed.

This isn't optional paperwork — it's the difference between getting most of your money at closing versus waiting six months for a refund. Canadian Aulani sellers who work through this process in advance consistently come out ahead of those who let the withholding happen and sort it out later.
