Dividend Withholding Tax Guide for Non-US Investors
The short answer
When a US company or fund pays a dividend to a non-US investor, the US generally withholds tax before the money leaves — 30% by default. A tax treaty between the US and your country often reduces the rate, commonly to 15% or 10%, if you have filed the form your broker requires (usually Form W-8BEN). The yield you see quoted is always the gross figure; what you receive is the net figure after this withholding.
Why calculators often mislead non-US investors
Most dividend calculators are built for US users and show gross income. For a non-US investor at a 30% withholding rate, a portfolio advertised as paying $1,000 a month actually delivers $700 before any local tax. Every calculator on this site therefore includes a withholding tax field, and the income goal calculator shows how much extra capital the tax implies: at a 3.5% yield, receiving $1,000 a month net requires about $342,857 with no withholding, but about $380,952 at 10% and roughly $489,796 at 30%.
Treaties, forms and local tax
Treaty rates depend on your country of tax residence and on correct paperwork; brokers normally collect Form W-8BEN at account opening and renew it periodically. Separately, your own country may tax the dividend again, sometimes with a credit for the US tax withheld. The interaction is country-specific, which is why this guide explains the mechanism rather than giving a universal rate — check your treaty rate and local rules, then enter your actual withholding rate into the calculators.
A practical routine
Once a year: confirm the withholding rate on an actual dividend statement from your broker, update the rate you use in the calculators, and re-check whether your income goal and timeline still line up. Small rate differences, compounded over decades, move the required capital by tens of thousands of dollars.
