ITIN Withholding Tax: How to Reduce 30% Withholding (2026)
What Are the US Withholding Rules That Apply to ITIN Holders?
| Income Type | Default Rate | Reduced With ITIN + Treaty |
|---|---|---|
| Dividends | 30% | 5-15% typical |
| Interest | 30% | 0-10% typical |
| Royalties | 30% | 0-15% typical |
| FIRPTA real-estate sale | 15% of gross | Refund via 1040-NR |
| Backup withholding (US resident) | 24% | 0% (with valid ITIN on W-9) |
How Do You Use the ITIN to Reduce Withholding?
- Confirm treaty eligibility. The recipient must be a tax resident of a country that has a tax treaty with the US.
- Complete Form W-8BEN. Enter the ITIN in Box 6, the treaty country in Box 9, and the article and rate in Box 10.
- Submit to the US payer. The payer applies the treaty rate to future payments.
- Renew every 3 years. Form W-8BEN expires at the end of the third calendar year after signing.
- For wages, use Form 8233 instead of W-8BEN. Same ITIN, different form.
What If the US Payer Already Withheld at 30%?
File Form 1040-NR for the affected tax year claiming the treaty rate. The 1040-NR computes the correct liability under the treaty; any difference between the 30% withheld and the treaty-rate liability is refunded. The ITIN must be active when the 1040-NR is filed. Refund claims are barred after 3 years from the original return's due date.
See ITIN tax treaty benefits for the country-by-country rate table.
Frequently Asked Questions About ITIN Withholding Tax
The default IRS withholding rate for US-source income paid to non-resident aliens is 30%. This applies to dividends, interest, royalties, capital gains in certain cases, and service payments. The rate drops to the treaty rate (typically 0-15%) when the recipient submits Form W-8BEN with a valid ITIN and treaty-country claim.
Form W-8BEN claims a treaty rate. The W-8BEN requires the recipient's name, country of residence, and a tax identifier (SSN, ITIN, or foreign tax ID). An ITIN is the most reliable identifier because US payers' automated systems accept and validate it immediately, applying the treaty rate to the next payment.
Backup withholding is 24% withholding the IRS requires when a US-tax-resident's tax ID is missing, invalid, or fails IRS validation. ITIN holders avoid backup withholding by providing a verified ITIN on Form W-9. Once the ITIN is on file, backup withholding does not apply.
FIRPTA (Foreign Investment in Real Property Tax Act) withholds 15% of the gross sale price when a foreign person sells US real estate. The seller's ITIN is required to file Form 8288-B to apply for a reduced withholding amount, and to file Form 1040-NR claiming any refund of over-withheld amounts.
Yes, by filing Form 1040-NR for the affected year claiming a refund of over-withheld tax. The 3-year statute applies. The 1040-NR computes the actual treaty-rate liability and the difference between withholding and liability becomes the refund. Without an ITIN, the claim cannot be filed.
