How It Works

The tax deducted from overtime depends on which income tax band it falls in:
- Basic rate (20%): income between £12,570 and £50,270
- Higher rate (40%): income between £50,270 and £125,140
- Additional rate (45%): income above £125,140
National Insurance is also deducted at 8% (up to £50,270) or 2% (above £50,270).
