Eli5 Do tax rates kick in at each cutoff? Or if you earn a set amount your full income is taxed at the same rate

Just wondering when looking at jobs putting me into higher tax brackets, if tax was say 20% for earning £30k, and £31k a year was taxed at 25%, would my first 30k of income be taxed at the 20% or my full salary taxed at 25%? And if so then how do you ever make jumping up to the next tax band viable?

Only the amount over the threshold is taxed at the higher rate. It’s virtually impossible to take home less after a pay rise due to the higher tax bracket – you’d have to be in a very unique situation with income support, benefits and tax credits that simultaneously expire.

As you’re in the UK you might want to try out this tax calculation tool, that also includes NI and student loan deductions:
