Built for the awkward bit of paperwork

The file tools run locally, including the heavier decoding, so a long PDF does not have to be trusted to someone else’s server. The UK calculators use the 2026/27 rates published by GOV.UK, HMRC and the Scottish Parliament, with the source written on each page. Scotland’s property tax and Wales’s are separate, and the stamp duty page says so.
