UK Tax Year 2026/27 · 200 build-time-computed pages

UK tax by profession, income and structure

Each page below renders its numbers from the same engines that power the live calculators: the joint salary-dividend optimiser, the inside-vs-outside-IR35 comparison, and the sole-trader engine. Inputs are read at build time from a single CSV row; outputs are computed afresh on every deploy.

For the methodology behind the pages, see the UK contractor tax guide and the Ltd Co director tax guide. For interactive versions, see the salary–dividend split, take-home and SIPP optimiser calculators.
