— Embed a calculator
Put an accurate tax calculator on your page — free.
The same five-step top-slicing relief calculator we run — and an always-current UK tax rates card — each embeddable in one paste. Verified to the penny against HMRC's worked examples, with the post-2021/22 PSA recalculation most tools still skip.
Top-slicing relief calculator
A live preview is below. Copy the snippet into any page — a blog post, a knowledge-base article, an adviser resources hub. It is responsive, needs no API key, and stores nothing.

</p>Accurate to the penny
The same deterministic engine our calculators run, regression-tested against HMRC's published worked examples on every change.
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.
UK pension & tax rates card
Every adviser site has a “useful numbers” page that goes stale each April. This card doesn't: the annual allowance, taper gates, MPAA, lump sum allowances and the income-tax, savings and dividend figures are read from the same HMRC-verified configuration our calculators run on, and roll over automatically each tax year. The full reference lives at paraplanai.co.uk/rates.

</p>Never goes stale
The card reads the versioned tax-year configuration our engine computes against — the April roll-over updates every figure on its own.
No tracking of your readers
Pure server-rendered HTML: the card stores nothing, asks for nothing and ships no scripts.
Engine-verified provenance
Each figure carries the config's HMRC verification date; the full, citable reference (with archives and history) lives at /rates.
One simple condition
Keep the attribution link in the snippet — “Powered by ParaplanAI” to our top-slicing relief calculator for the calculator, “Rates by ParaplanAI” to the rates reference for the card. 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.
