FIRPTA vs Capital Gains Tax: Understanding the Difference
FIRPTA and capital gains tax are not two separate taxes (they are two parts of the same tax collection process. FIRPTA is how the IRS collects a deposit upfront at closing; capital gains tax is the actual tax you owe on your profit. Understanding the relationship between them is the key to understanding why most DVC sellers get a large portion of their withholding back.
Capital Gains Tax: The Actual Tax
When you sell any capital asset) a stock, a property, a DVC contract (and you have made a profit over your purchase price, the profit (called a capital gain) is taxable in the US. The rate depends on how long you held the asset:
- Long-term capital gain: Held more than one year. For non-resident individuals, the rate is typically 15% on the net capital gain.
- Short-term capital gain: Held one year or less. Taxed as ordinary income) up to 30% for non-residents under the flat rate provisions of the US tax code.
Your capital gain = sale price minus your adjusted cost basis. If you sold your DVC for $25,000 and your adjusted cost basis (original purchase price plus qualifying closing costs) is $18,000, your gain is $7,000 and your US federal tax is $1,050 (at 15%).
FIRPTA: The Withholding Mechanism
FIRPTA (Foreign Investment in Real Property Tax Act) is not a separate tax (it is a mandatory withholding mechanism applied to real property sales by foreign persons. The 15% is withheld at closing to make sure the IRS receives some payment before the seller leaves the country. The withholding is based on the gross sale price, not the gain.
The withholding is not your final tax) it is a prepayment. The final tax is whatever your capital gains calculation shows on your Form 1040-NR.
The Gap Between Withholding and Actual Tax
The withholding is 15% of the full sale price. The actual tax is 15% of the gain. Because the gain is always less than the full sale price, the withholding almost always exceeds the actual tax. The excess is refunded when you file your return.
| Item | Example Figures |
|---|---|
| Sale price | $25,000 |
| FIRPTA withholding (15% of $25,000) | $3,750 |
| Original cost basis | $18,000 |
| Capital gain (sale price minus basis) | $7,000 |
| Capital gains tax (15% of $7,000) | $1,050 |
| Refund (withholding minus actual tax) | $2,700 |
When the Withholding Rate and the Tax Rate Are the Same
Both FIRPTA withholding and long-term capital gains tax happen to use 15% as their rate. But they apply to different bases: withholding is 15% of the price, capital gains tax is 15% of the profit. That is why the withholding overpays (you are withholding 15% of $25,000 but only owe 15% of $7,000.
Capital Gains vs FIRPTA: A Quick Reference
| Feature | FIRPTA Withholding | Capital Gains Tax |
|---|---|---|
| What it applies to | Gross sale price | Net capital gain (sale price minus basis) |
| When collected | At closing (upfront) | When you file your tax return |
| Rate | 15% (standard) | 15% long-term / 30% short-term |
| Who computes it | Closing agent | You (on Form 1040-NR / Schedule D) |
| Who benefits from the difference | You get a refund | IRS keeps actual tax |
Tax Treaties and Capital Gains
The US has tax treaties with many countries that address capital gains. For DVC sellers, the key point: most US tax treaties preserve the US right to tax gains on US real property interests (including DVC). The treaty prevents double taxation but does not eliminate the capital gains tax in the US or the FIRPTA withholding mechanism. See your country's specific guide: UK, Canada, Australia.
Frequently Asked Questions
Is FIRPTA a tax or a withholding?
FIRPTA is a withholding mechanism) a mandatory prepayment of US capital gains tax collected at closing. It is not a separate tax in addition to capital gains tax. The 15% withheld at closing is credited against your actual capital gains tax liability when you file Form 1040-NR.
Why is the FIRPTA withholding different from my actual US tax?
The withholding is 15% of the gross sale price. Your actual tax is 15% of your capital gain (sale price minus your cost basis). The gain is always less than the sale price, so the withholding overshoots the actual tax (generating a refund for most sellers.
Do I pay capital gains tax and FIRPTA tax?
You pay capital gains tax. FIRPTA is just the mechanism for collecting it early. The 15% withheld at closing is your prepayment. When you file your return, you calculate what you actually owe and either get a refund (most common) or pay the difference.
