CoolTaxTool
UK tax calculator with charts for take-home pay, salary sacrifice and pension contributions.
What it does
Calculates and charts UK taxes to help with decisions such as personal pension contributions and salary sacrifice, in the browser at cooltaxtool.com or locally. Needs git, Node.js and npm: clone, npm install, npm start; the master branch deploys to the live site. The README states no disclaimer and does not say which tax years are covered, so check the live site before relying on a figure.
Where it fits on the map
Not on the map: for individual taxpayers.
The map places maintained projects for a company tax department or a tax authority, without a demo or paid-service flag. Everything else stays on the list with its label.
