<p style="font-size:.85em;">Calculator by <a href="https://freelancetally.com/tools/self-employment-tax-calculator/">FreelanceTally</a></p>

The only condition: keep the visible credit link under the widget. You can change the height (760px fits the full breakdown) and the border styling to match your site.

What your readers get

The same 2025–2026 federal SE-tax estimate as the full tool — Social Security and Medicare split, the deductible half, and a per-quarter set-aside — computed entirely client-side from IRS/SSA published constants. The widget links back to the full page for the formulas, sources, and saved-scenario comparison. Estimates only, not tax advice.
