Dividend Withholding Tax (WHT)
The Formal Definition
A statutory tax deducted at source by foreign governments on dividend payments distributed to non-resident investors.
Net Dividend = Gross Dividend × (1 - WHT Rate)
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Withholding tax is the cross-border toll booth. If you live in Europe or Asia and buy US-domiciled stocks without treaty protection, the IRS takes 30% of your dividend before it ever hits your account. That's a 30% cut on your compounding engine."

How Brokers Weaponize This Term
Brokers fail to assist non-US residents with W-8BEN compliance, resulting in an automatic 30% default withholding on US stock dividends instead of the reduced 15% treaty rate.
