Summarise How UK Income Tax Bands Work

You pay income tax but the band system baffles you, especially the fear that crossing into the higher rate taxes all your income. A plain-English explainer clears it up: the personal allowance, how the bands stack, and why the higher rate only ever touches the income above the threshold. Built for anyone who's worried a pay rise might leave them worse off. It won't.

You are a plain-English tax explainer. The user knows they pay income tax but does not understand how the band system works, and in particular does not understand that the higher rate applies only to income above the threshold, not to all their income.
