Employee National Insurance in the UK (2026-27): Rates, Thresholds and State Pension
UK employees pay Class 1 National Insurance at 8% on earnings between the Primary Threshold (£12,570) and the Upper Earnings Limit (£50,270), then 2% on everything above £50,270. The contributions are deducted by the employer via PAYE alongside income tax and fund entitlement to the State Pension and certain other benefits.
What National Insurance is and what it funds
National Insurance contributions (NICs) are a compulsory levy on earnings paid by employees, employers, and the self-employed. Unlike income tax, NI is specifically linked to entitlement: paying it (or being credited) builds up qualifying years that count towards the new State Pension, Statutory Sick Pay, Statutory Maternity Pay, and contributory Employment and Support Allowance. Employee contributions are called Class 1 NICs and are deducted by the employer via PAYE at the same time as income tax. Employer Class 1 secondary contributions are an additional levy paid by the business on top of gross pay — they do not reduce an employee's take-home pay directly, but they represent a cost of employment. This guide covers only the employee (primary) Class 1 contributions. National Insurance is a reserved matter: it is set by the UK Parliament and applies identically across England, Wales, Scotland, and Northern Ireland. The devolved income tax powers that Scotland has do not extend to NI. Two workers earning the same salary — one in Edinburgh and one in Bristol — will pay identical Class 1 NI despite potentially paying different income tax.
The 2026-27 Class 1 employee NI thresholds and rates
Three thresholds shape how Class 1 employee NI is calculated: Lower Earnings Limit (LEL): £6,708 per year (£129 per week, £559 per month). Earnings between the LEL and the Primary Threshold accrue NI credit — building your State Pension record — but no cash NI is deducted. Primary Threshold (PT): £12,570 per year (£242 per week, £1,048 per month). This is aligned with the income tax Personal Allowance. NI at 8% starts only once earnings exceed this threshold. Upper Earnings Limit (UEL): £50,270 per year (£967 per week, £4,189 per month). This is aligned with the higher rate income tax threshold. Earnings above the UEL attract NI at the reduced rate of 2%. The formula for annual employee NI (Category A — the standard rate for most employees below State Pension age): 8% multiplied by the amount of earnings between £12,570 and £50,270, plus 2% multiplied by earnings above £50,270. Earnings at or below £12,570 are NI-free. In practice, payroll systems compute NI each pay period using the period-equivalent thresholds (weekly or monthly); the annual figures above are an approximation used in calculators.
How salary sacrifice reduces National Insurance
Salary sacrifice is a contractual arrangement where you give up part of your gross pay in exchange for a non-cash benefit — most commonly employer pension contributions. Because the sacrifice reduces your contractual pay before PAYE and NI are calculated, the savings are more valuable than making a post-tax personal contribution. For 2026-27, a salary sacrifice into a pension reduces both income tax and National Insurance. On NI specifically, a basic rate employee saves 8% of the sacrificed amount in employee NI (on amounts up to the Upper Earnings Limit), plus 13.8% in employer NI (which the employer may or may not pass on). The employee NI saving is the more immediate benefit: sacrificing £1,000 into a pension saves £80 in employee NI for a Category A employee earning below £50,270. Salary sacrifice for pension purposes retains its NI-exempt status until 5 April 2029, when a reform will limit the NI exemption to the first £2,000 per year of pension salary sacrifice. Income tax relief on salary sacrifice pension contributions remains unaffected and is permanent. Before sacrificing salary, check that your remaining cash pay does not fall below the relevant National Minimum Wage rate — the floor for workers aged 21 and over in 2026-27 is £12.71 per hour.
NI category letters: when the standard rate does not apply
HMRC assigns each employee a National Insurance category letter that determines which NI rates apply. Most employees are Category A (the standard rates described above). Other common categories include: Category B: Married women or widows exercising the right to pay the reduced rate — a legacy option no longer available to new entrants. The reduced rate is lower than Category A below the UEL. Category C: Employees who have reached State Pension age. Category C means zero employee NI is payable — once you are drawing or entitled to the State Pension, you no longer need to contribute through Class 1 (though your employer still pays secondary contributions). Category H, M, Z: Various reduced-rate options for apprentices or workers with multiple employments where NI deferral applies. Your employer determines and applies the correct category. If you believe your category is wrong — for example, you have reached State Pension age but are still being deducted NI — contact HMRC or your employer's payroll department. Overpaid NI can be reclaimed.
Building your State Pension record through National Insurance
The new State Pension (introduced for those reaching State Pension age on or after 6 April 2016) requires 35 qualifying years of NI contributions or credits to receive the full amount, and a minimum of 10 qualifying years to receive any State Pension at all. A qualifying year is a tax year in which you pay, are credited with, or are treated as having paid a minimum level of NI. Employment earnings between the Lower Earnings Limit (£6,708) and the Primary Threshold (£12,570) generate NI credits without any cash payment — your record is protected even though no NI is deducted. Earning above the Primary Threshold means paying Class 1 cash contributions that directly add qualifying years. Gaps in your NI record can be filled voluntarily by paying Class 3 NI contributions. The decision to fill gaps is one where the cost of contributions must be weighed against the additional State Pension entitlement gained over your expected retirement period. This is an area where financial advice from a regulated adviser can be particularly valuable.
FAQ
Is National Insurance the same in Scotland as in the rest of the UK?
Yes. National Insurance is a reserved matter set by the UK Parliament and applies identically across all four nations. The Scottish Parliament's income tax powers do not extend to NI. A Scottish employee earning the same salary as an English employee will pay identical Class 1 NI, even though their income tax bill may differ significantly.
What happens to my National Insurance when I reach State Pension age?
Once you reach State Pension age (currently 66 for both men and women), you stop paying employee Class 1 NI — you are moved to Category C. Your employer continues to pay employer secondary NI on your earnings, but no employee deduction is made. You do not need to do anything to claim this; your employer should update your NI category automatically. If NI is still being deducted after you reach State Pension age, contact your employer or HMRC.
Can I see how many qualifying NI years I have built up?
Yes. You can check your NI record and State Pension forecast via the Check Your State Pension service on GOV.UK (you will need a Government Gateway account). The record shows each tax year from your working history, whether it is a full qualifying year, a partial year, or a gap. It also projects your forecast State Pension amount based on your current record.
Does my employer's National Insurance affect my take-home pay?
Employer (secondary) Class 1 NI does not appear on your payslip and is not deducted from your gross salary. It is an additional cost that the employer pays on top of your gross pay to HMRC. However, it affects employment decisions indirectly: high employer NI costs can influence pay negotiations, bonus structures, and whether employers offer salary sacrifice arrangements (which reduce their NI liability as well as yours).
