— Embed a calculator
Put an accurate tax calculator on your page — free.
The same five-step top-slicing relief calculator we run, embeddable in one paste. Verified to the penny against HMRC's worked examples, with the post-2021/22 PSA recalculation most tools still skip.

No tracking of your readers
The widget stores nothing and asks for nothing — figures are computed in the browser.
Always current
Bands, allowances and the PSA recalculation update with each tax year; your embed stays right without you touching it.
One simple condition
Keep the “Powered by ParaplanAI” attribution link in the snippet, pointing to our top-slicing relief calculator. That visible credit is all we ask in return for the tool. Don't alter the calculation or imply ParaplanAI endorses your site or provides advice — the widget illustrates; it doesn't advise.
