Sales Tax Calculator Widget

Give your readers and clients the same sales tax calculator we run on our own site. It looks up the combined rate for any US ZIP code or Canadian province and works out the tax on a price. Copy the code below and paste it into your page.

How to add it to your site

The widget is a standard iframe, so it works anywhere you can paste HTML. Copy the code, then add it where you want the calculator to appear:

  • WordPress: add a Custom HTML block and paste the code into it.
  • Squarespace: add a Code block.
  • Wix: add an Embed HTML element (Embed code, then Embed HTML).
  • Webflow: drag in an Embed element.
  • Any other site: paste the code into the page’s HTML.

Paste the whole code, including the line under the iframe. The widget keeps its own layout from 320 pixels wide up, so it fits a sidebar or a phone screen. If visitors have to scroll inside the widget, pick a taller height.

Options

The picker above writes these for you. To set them by hand, add them to the iframe’s src:

  • state=TX opens on a US state (its two-letter code), with an example ZIP code for that state.
  • country=ca switches to Canada, and province=BC opens on a province with its rate already showing.

Width and height are ordinary iframe attributes. The code caps the width at the width of your column, so a fixed-width widget still fits on phones.

What your visitors get

The same rates as the Kintsugi sales tax calculator: the state, county, city and district rate for a ZIP code, including announced rate changes from the day they take effect, and GST, HST and PST for Canada. The widget loads none of our ad or analytics trackers and shows no cookie banner inside your page.

Terms of use

The widget is free to use on any website, commercial or not, on these terms:

  • Keep the attribution. The “Powered by Kintsugi” line inside the widget and the line under it must stay visible and link to Kintsugi. You may add a rel attribute such as nofollow to the link if your site’s policy calls for one.
  • Don’t alter the widget, cover or crop the attribution, or present the calculator as your own.
  • Use the widget as it is embedded. Calling the rate lookups behind it directly, or loading the widget automatically at high volume, isn’t permitted.
  • The calculator is for illustration, provided as-is and without warranties, and isn’t tax advice. Rates are estimates for a ZIP code; confirm the rate for the exact address before you file.
  • We may change the widget, limit how it’s used, or withdraw it at any time. Using it also means accepting our terms of service.
