Tax on Overtime Calculator — FAQs
Is overtime taxed more?
Same bands — but extra pay lands in your top bracket. £500 overtime at 40% + 2% NI keeps £290; at basic rate it keeps £360.
Pushed into a higher band?
Only the slice above the threshold pays the higher rate — a raise or overtime can never reduce your total take-home.
