About StampBand
StampBand covers the three property transaction taxes charged across the United Kingdom, each from its authority's published rate tables. It is published by Inventum, an Australian-registered company, and is not a government service.
What this site covers
The United Kingdom does not have one stamp duty. It has three separate taxes, with different authorities, bands, and rules for first-time buyers and additional properties. Stamp Duty Land Tax covers England and Northern Ireland, collected by HM Revenue & Customs; Land and Buildings Transaction Tax covers Scotland, collected by Revenue Scotland; Land Transaction Tax covers Wales, collected by the Welsh Revenue Authority. StampBand publishes each regime's rate tables, a band-by-band breakdown across a wide ladder of prices, and a comparison of what one price costs under all three. No authority publishes a page for a specific price, or a view across the three. That is why this site exists.
Who publishes it
StampBand is published by Inventum, a company registered in Australia. The site reports on United Kingdom taxes, but the publisher is not based there and does not claim to be. Content is attributed to StampBand Editorial, not to an individual, because what produces a figure here is a pipeline rather than an author: a committed dataset keyed from official pages, one calculation module, and a build gate that refuses to ship when a figure disagrees with the relevant government's own calculator. The methodology page sets that process out in full.
Not a government site
StampBand is not affiliated with, endorsed by, or acting for HM Revenue & Customs, Revenue Scotland, the Welsh Revenue Authority, or any United Kingdom government body. Nothing here is an official ruling, and the site is not a route to file or pay. The rate tables come from those authorities' published pages, used under the Open Government Licence v3.0. Where a figure here and the authority's differ, the authority is right and we want to be told.
Where the figures come from
Rates are keyed by hand from each authority's published tables into a dataset committed to the site's code, and every figure is computed from it by one shared calculation module - the same module that runs the on-page calculator, so a page and the calculator cannot drift apart. A fixture set of 43 cases is then re-driven against the three governments' own calculators, and the build fails if any case disagrees.
What this site does not do
StampBand gives general information, not financial, tax or legal advice. Multiple dwellings relief, linked transactions, mixed-use property, leasehold premium and net present value calculations, corporate purchases and any relief not named on the page all sit outside what the calculator computes. For those, read the authority's guidance and speak to your conveyancer, who files and settles the tax due.
How it is funded
The site is free and funded by advertising. Advertisers have no sight of, and no influence over, the rate tables, the calculations, or anything written here. Questions and corrections go to support@inventum.com.au.
