Embed a Free Tax Calculator Widget on Your Blog or Website

The best content gives readers something they can use, not just read. A tax calculator widget is exactly that: a practical tool your audience can interact with right on your page, without clicking away to another site.

Our embeddable widget adds a fully functional freelance tax calculator to any HTML page. It covers all 6 countries (Philippines, India, Indonesia, Malaysia, Thailand, Vietnam) and includes the expat toggle for non-resident calculations.

Who Is This For?

• Freelancer community blogs — Give your readers a calculator without sending them off-site
• Expat and digital nomad forums — Help users quickly compare tax scenarios between countries
• Remote work job boards — Add practical value alongside your listings
• Personal finance blogs — Enhance your tax articles with an interactive tool
• Country-specific business guides — Provide actionable value for entrepreneurs

How to Embed

It takes two minutes. Head to our Widget Generator, pick a country, and copy the code. Paste it into any page that supports HTML. The iframe auto-resizes so you don't need to guess a height.

<iframe src="https://taxcalc.asia/embed/ph"
  style="width: 100%; border: none; overflow: hidden;"
  loading="lazy"
  title="Philippines Tax Calculator">
</iframe>

The Widget Generator also includes the JavaScript snippet that auto-resizes the iframe. Copy the full code from there.

What the Widget Can Do

• Full tax calculation — Enter income, get tax owed, take-home, monthly breakdown, effective rate
• Expat toggle — Switch between resident and non-resident tax rates
• Country-specific options — Each widget includes unique inputs per country
• Fully responsive — Works on mobile, tablet, and desktop
• No external dependencies — Just one iframe and one script tag
• Zero server load — All calculation runs in the browser

Widget Tips

• Place it after relevant content — Embed after your tax guide so readers can read, then calculate
• Use a call-to-action — Drive more clicks with a clear prompt above the widget
• Link to the full calculator — The widget includes a link to the full Chart.js breakdown
• Embed multiple countries — Compare two countries side by side for your readers

Technical Details

The widget is a static HTML page from taxcalc.asia. It communicates its height using postMessage so the iframe always fits without scrollbars. No cookies, no tracking, no external requests from the widget itself.
