Embed the Estate Tax Calculator

Whether an estate owes federal tax at all, using the 2026 exclusion of $15,000,000 a person, and what the 40% rate costs on anything above it. Set the values it should open on, then copy the iframe. Your visitors can change them; the widget recomputes against Rule Calculator and never touches your page.

Opening values

Set what the widget shows before anyone touches it. Leave a field as it is and it stays out of the URL.

Free for commercial use. The one condition is the credit link inside the widget, which is how the calculator stays free. Want the numbers in your own markup instead? The same calculator is a JSON endpoint, or see the full Estate Tax Calculator page with its sources and working.
