Foreign Tax Credit & Withholding Estimator

Why this matters specifically for diaspora investors

If you're a U.S. taxpayer holding dividend-paying stocks on an African exchange, most countries withhold tax at the source before the dividend ever reaches you, commonly 8 to 20% depending on the country and any applicable tax treaty. The U.S. then, in principle, taxes that same dividend income again as part of your worldwide income. Without relief, that income would be taxed twice.

The Foreign Tax Credit, claimed on IRS Form 1116, exists to prevent exactly this. It lets you credit foreign tax already paid against your U.S. tax liability, dollar for dollar, up to a limit tied to how much U.S. tax is attributable to that same foreign income.

This calculator gives a simplified estimate of that mechanic. The real Form 1116 calculation involves separate income "baskets" (passive vs. general category), apportionment of deductions, and other technical limitations this tool does not fully model — treat this as a starting estimate for planning conversations, not a filing-ready number.

Cross-border investing shouldn't mean cross-border tax surprises

Most generalist investing tools are built entirely around a single-country U.S. investor. If you're part of the diaspora holding assets, family obligations, or investments that span both the U.S. and home, the tax mechanics genuinely are more complex, and getting them wrong can mean either overpaying or facing penalties down the line.

This estimator is meant to give you the shape of the calculation so you can walk into a conversation with a qualified international tax professional already understanding the mechanism, not starting from zero.
