Free Tax Calculator Widgets for Accounting and Tax Sites

Clients ask the same estimating questions every year, usually before they are ready to book time. A calculator on the page answers the easy version, and the ones who need real advice still call — better informed.

Paste one line of HTML and the Income Tax Calculator runs on your page — free, with no signup and no limit on traffic. Calculations happen in the visitor's browser, so nothing they type is sent anywhere.

The only condition is that the "Powered by Tallivo" link stays, as a normal followed link.

Income Tax Calculator — live preview

This is the real widget at its real URL — what you see is exactly what your visitors get.

Where accountants, bookkeepers and tax bloggers put it

  • On a service page, ahead of the enquiry form
  • In a seasonal blog post about brackets or deadlines
  • On a client-resources page, alongside your own guidance

Also useful for you

Every calculator on the site can be embedded the same way. For accountants, bookkeepers and tax bloggers, these tend to earn their place:

Performance, privacy and attribution

Performance. The widget is a lazy-loaded iframe, so it cannot block your page rendering and is only fetched when scrolled near. It ships no ads and no analytics of its own.

Privacy. Every figure is computed in the browser. There is no backend that receives your visitors' inputs, so embedding this does not add a data processor to your site.

Attribution. Keep the "Powered by Tallivo" link, followed and visible. Please don't add nofollow or hide it with CSS. That link is what pays for the calculator being free.

Accuracy. The figures are the same ones the site runs on, documented in the methodology and dated on each page. Our editorial policy explains how they are checked, and corrections is how to tell us if one is wrong.

Questions accountants, bookkeepers and tax bloggers ask

Are the figures actually current, and can I check them?
Every page carries the tax year and the date the data was last verified against its source, and the methodology page lists the exact Revenue Procedure and state schedules used. If you find a figure that is wrong, the corrections page explains how to report it and we will fix it — that route exists precisely because professionals check.
What does it cost, and is there a catch?
Nothing, and no. There is no signup, no key, no usage limit and no expiry. The widget carries one small 'Powered by Tallivo' link back to the calculator — that link is the entire business model, and it is the only thing we ask.
Will it slow my page down?
It loads in an iframe with loading="lazy", so the browser only fetches it when it is close to the viewport, and it cannot block your page's own rendering. The embed carries no ads and no third-party analytics.
Can I match it to my site's colours?
There is a light and a dark theme, set with ?theme=day or ?theme=night in the iframe URL — the host page chooses, so the widget matches your design rather than the visitor's system preference. Beyond that the widget keeps its own styling, which is what lets us support it without breaking your layout.
Do I have to keep the attribution link?
Yes — it is the condition of free use, and it must stay a normal followed link. Other than that you can place the widget wherever you like, on as many pages as you like, including commercial ones.

Free to embed on commercial and non-commercial sites alike. Calculators are estimates for general information, not financial, tax or legal advice — that disclaimer travels with the widget.
