A simple single page indicative UK tax calculator with some novel metrics and calculations. Accepts other forms of income to give a more complete overview. Rationale: I disliked most of the existing ones and they are full of adverts and such. Should handle the complexities around income bands and child benefit tax traps. Also handles Scottish tax bands and shows Cost To Employer incorporating employment taxes.
