How much National Insurance do I pay on £50,000?
As an employee, you pay £2,994.4/year in NI. If self-employed, you pay £2,425.2/year (Class 2 + Class 4 combined).
How much does my employer pay in NI?
On a £50,000 salary, your employer pays £6,750 in employer NI (15% on earnings above £5,000). The total cost of employing you is £56,750.
Why is employee NI (8%) higher than self-employed Class 4 (6%)?
Employees also benefit from employer NI contributions. The combined employee + employer NI rate (8% + 15% = 23%) is much higher than the self-employed rate (6% + flat Class 2). This reflects the broader social security coverage employees receive.
Do I pay NI on earnings below £12,570?
No. Employee NI starts at the Primary Threshold (£12,570). However, you build NI credits from the Lower Earnings Limit (£6,396), protecting your state pension entitlement even if you pay no NI.
Is NI deducted before or after income tax?
NI and income tax are calculated independently on gross pay. They use different thresholds — income tax uses Personal Allowance (£12,570 with taper), while NI uses fixed thresholds with no taper at higher incomes.
