Treaty: Domestic — no cross-border withholding

Citation: IRC §§ 1441–1446 (withholding applies to foreign persons; US residents not subject to WHT on US-source dividends)

U.S. residents receiving U.S.-source dividends: no cross-border withholding; taxed on return at qualified (0/15/20%) or ordinary rates.

Estimates for educational purposes only. Tax rules change; consult a qualified tax professional for your specific situation. Dividend-tax treatment depends on holding period, account type (taxable vs. retirement), investor type (individual vs. pension vs. mutual fund), limitation-on-benefits tests, and other factors not modeled here.
