Put a live tax calculator in your next article
If you write about freelancing, gig work, or self-employment taxes, a paragraph that says “use the IRS mileage rate” is fine. A calculator your reader can actually use, right there in the article, is better. Paste one iframe tag and any calculator below runs live on your page, on your domain, styled to fit your content column.
The numbers are worth trusting. Every rate and threshold behind these calculators is pinned against IRS primary sources, updated for the 2026 tax year, and each calculator shows its sources to your readers. Because the iframe loads the live calculator, your embedded copy updates the moment we do.
There is one requirement: keep the short attribution line included in the snippet — the “Powered by” credit and link that sits just below the calculator. That link is what makes the whole thing free.
Quick start
Pick a calculator, copy the code, paste it into your page’s HTML, and preview the result before you publish.

- Free for any site. Blogs, newsletters, accounting firms, gig-economy communities. No signup, no fees, no usage cap.
- Keep the attribution line.The snippet places a short “Powered by” credit, linking back to the calculator, just under the embed. Leaving that line in place is the one condition of free use.
- Present it as an estimate. The calculators are educational tools, not professional tax advice, and your page should not frame their output as a substitute for an accountant or tax professional.
- Numbers update automatically. The iframe loads the live calculator, so rate changes and new tax years reach your page on their own. You never need to re-embed.
