An employee’s Class 1 National Insurance is made up of contributions:

• deducted from their pay (employee’s National Insurance)
• paid by their employer (employer’s National Insurance)

The amounts deducted and paid depend on:

• the employee’s National Insurance category letter
• how much of the employee’s earnings falls within each band

ExampleIf you’re in category A and you earn £1,000 in a week you’ll pay:

• nothing on the first £166
• 12% (£95.52) on your earnings between £166.01 and £962
• 2% (£0.76) on the remaining earnings above £962

This means your National Insurance payment will be £96.28 for the week.
