Employer National Insurance: £4,500

Employer NI is charged at 15% on all earnings above the Secondary Threshold of £5,000:

• Earnings above threshold: £35,000 - £5,000 = £30,000
• Employer NI: £30,000 x 15% = £4,500
• Monthly employer NI: £375

This is an effective rate of 12.9% on the gross salary. Unlike employee NI, there is no upper earnings limit for employer NI — it's a flat 15% on everything above £5,000.

Pension auto-enrollment: £862.8

UK employers must auto-enroll eligible workers into a workplace pension. The minimum employer contribution is 3% of qualifying earnings.

Qualifying earnings are the portion of salary between £6,240 and £50,270:

• Qualifying earnings: £35,000 - £6,240 = £28,760
• 3% contribution: £28,760 x 3% = £862.8/year (£71.9/month)

At 5%, this would be £1,438/year. At 8%, it would be £2,300.8/year.
