General rule for NRA capital gains
A non-resident alien (NRA) is generally not subject to US tax on capital gains from US-source assets (e.g. publicly-traded US stocks, bonds, options) unless: the NRA is present in the US for 183+ days in the tax year (special rule — different from the SPT residency test), OR the gain is ECI, OR FIRPTA applies
USRPI treatment under FIRPTA
Under IRC §897, gain from the disposition of a US Real Property Interest (USRPI) by a non-resident is treated as ECI and taxed at normal graduated rates.IRC §897
USRPI includes
US real property (land, buildings); Interests in a US Real Property Holding Corporation (USRPHC) — a domestic corporation where > 50% of the fair market value of its assets consists of USRPIs
USRPI does NOT include
Interests in publicly-traded REITs below 5% ownership threshold; Interests in domestic corporations that are not USRPHCs
Buyer withholding obligation
The buyer must withhold from proceeds: 15% of the gross sales price (general rule); 10% if the property will be used as the buyer's residence AND price ≤ $1,000,000; 0% if price ≤ $300,000 AND buyer intends to use as primary residence

Treatment of withheld amounts
Withheld amounts are payments on account. The NRA files a US return (Form 1040-NR) and the withholding is credited against actual tax owed.
Withholding certificate application
The seller can apply for a withholding certificate to reduce withholding to the estimated actual tax on the gain (rather than 15% of gross proceeds). Must apply before or on the date of transfer. IRS has 90 days to act.Form 8288-B
ECI taxation
Gains from assets used in, or held for, a US trade or business are treated as ECI and taxed at normal graduated rates on Form 1040-NR.
No US tax on publicly-traded stock gains
A non-resident alien selling shares in a US publicly-traded company (not a USRPHC) — e.g. Apple, Google, Microsoft — does not pay US tax on capital gains from those shares. This is one of the most widely misunderstood points.

Treaty reduction of capital gains taxation
Many US DTAs reduce or eliminate US taxation of capital gains for NRAs: Article 13 of OECD-model treaties typically grants exclusive residence-country taxation of gains on personal property (non-real property); FIRPTA gains may still be taxed by the US under most treaties (real property carve-out)
