Short answer
£50,000 sits below the standard higher-rate threshold
With these assumptions, the first £12,570 is covered by the Personal Allowance and the remaining £37,430 is taxed at 20%. No part of this £50,000 employment income reaches the 40% band. Bonuses, taxable benefits, other income or a reduced allowance can change that; Scottish Income Tax uses different bands.
National Insurance, pension and student loan deductions can change the final amount that reaches your account each month.
Decision context
Use this salary as a comparison point
A move from £40,000 to £50,000 increases gross salary by £10,000. Compare the net monthly gain after deductions and any change in commuting, working hours or benefits. £50,000 is not itself a statutory Income Tax threshold.
