If you've ever looked at a UK payslip and watched your gross pay shrink before it reaches your bank account, National Insurance is one of the two big reasons why. It appears on almost every payslip in the country, sitting alongside income tax as the deductions that turn your gross salary into your actual take-home pay. This guide explains exactly what National Insurance is, the employee national insurance rates for 2026-27, the thresholds that decide how much national insurance you pay, and how it's calculated — with the verified numbers you'll see on your own payslip. ## What Is National Insurance? National Insurance is a tax on earnings that builds your entitlement to the State Pension and certain benefits, including maternity allowance and contributory Employment and Support Allowance. Employees pay Class 1 National Insurance, which is deducted directly from your pay by your employer and sent to HMRC alongside the income tax they withhold from you. A quick clarification worth making: this article is about National Insurance contributions — the tax on your earnings. It is not about your National Insurance number, which is simply the unique personal identifier HMRC issues you (the two-letter, six-digit, one-letter string like AB 123456 C) and which stays with you for life. The number identifies you; the contributions are what you actually pay. ## Employee National Insurance Rates for 2026-27 For the 2026-27 tax year (6 April 2026 to 5 April 2027), employee Class 1 National Insurance is charged on a banded basis. The rate you pay depends on which slice of your earnings each pound falls into. The Primary Threshold is where NI starts, and the Upper Earnings Limit is where the rate drops. Here are the national insurance rates 2026-27 for an employee on Category A (the most common category — you're not in a contracted-out pension scheme and qualify for the full State Pension): Band of earnings NI rate Up to £12,570 (Primary Threshold) 0% £12,570 to £50,270 (Upper Earnings Limit) 8% Above £50,270 2% These rates apply to Class 1 Category A — the standard employee category. Lower rates apply to some other categories (for example, married women with reduced-rate elections or employees in certain contracted-out arrangements), but most UK workers fall under Category A. ## How Is National Insurance Calculated? To see how is national insurance calculated in practice, let's work through two examples using the 2026-27 rates — one salary below the Upper Earnings Limit and one above it. ### Example 1: £30,000 salary On a £30,000 salary, all of the NI-able earnings fall between the Primary Threshold (£12,570) and the Upper Earnings Limit (£50,270), so the full 8% rate applies to the band: - Earnings above the Primary Threshold: £30,000 − £12,570 = £17,430 - NI at 8%: 8% × £17,430 = £1,394.40 - NI at 2%: £0 (earnings are below the Upper Earnings Limit) - Total National Insurance: £1,394.40 So an employee earning £30,000 pays £1,394.40 in Class 1 National Insurance for 2026-27 — on top of their income tax. This is the most common scenario, where a single 8% rate covers all NI-able pay. ### Example 2: £60,000 salary At £60,000, the salary crosses the Upper Earnings Limit, so NI is split across both the 8% and 2% bands: - 8% band (£12,570 to £50,270): 8% × £37,700 = £3,016.00 - 2% band (above £50,270): 2% × (£60,000 − £50,270) = 2% × £9,730 = £194.60 - Total National Insurance: £3,016 + £194.60 = £3,210.60 Notice how the rate drops to 2% once earnings pass £50,270 — so the extra pounds above the Upper Earnings Limit attract a much smaller NI charge. This is the opposite pattern to income tax, where higher earnings push you into a higher rate, not a lower one. ## The NI Thresholds Explained National Insurance uses two thresholds that decide where each rate applies. The Primary Threshold is the point at which NI starts — earnings below £12,570 for 2026-27 attract 0% NI, so lower-paid workers can earn up to that amount before any National Insurance is deducted. The Upper Earnings Limit is the point at which the rate drops. Earnings between £12,570 and £50,270 are charged at the main 8% rate, and earnings above £50,270 are charged at the lower 2% rate. The Upper Earnings Limit sits at the same level as the point where the higher rate of income tax begins — but the thresholds themselves are independent NI thresholds, not income tax ones. A useful point worth noting: in 2026-27 the Primary Threshold happens to also be £12,570 — the same figure as the income tax Personal Allowance. But they are separate thresholds set by separate rules, and there is no guarantee they will always match. NI uses its own band structure, so always treat the two as distinct even when the numbers coincide. ## Employee, Employer & Self-Employed NI National Insurance is not just one charge. Employee Class 1 NI — the 8% and 2% rates above — is deducted directly from your pay and is what most workers see on their payslip. It's the headline figure when people ask how much national insurance do I pay. On top of that, employers separately pay secondary Class 1 NI on their employees' earnings. This employer NI is paid by the employer on top of your salary — it is not deducted from your pay, so it does not reduce your take-home. It does mean the total cost of employing you is higher than your gross salary, but your payslip only shows your own employee NI. Self-employed workers pay Class 4 NI instead, which is a different system with its own thresholds and rates, settled through self assessment rather than PAYE. This guide focuses on employee Class 1 NI; if you're self-employed, the bands and calculation differ. ## How Salary Sacrifice Cuts Your National Insurance One of the most effective ways to reduce the National Insurance you pay is salary sacrifice — particularly for pension contributions. When you sacrifice part of your salary into a workplace pension, that sacrificed amount is no longer part of your NI-able earnings, so both your income tax and your National Insurance fall. This is a key difference from some other deductions. A standard relief-at-source pension contribution (where you pay in from net pay and get tax relief added) lowers income tax but does not lower NI, because NI is calculated on your gross pay before the contribution. Salary sacrifice, by contrast, reduces the gross pay itself — so it cuts both taxes at once. For a higher earner especially, salary sacrifice can be one of the biggest legitimate levers for cutting the NI line on your payslip. We cover the mechanics in detail in our guide to [pension salary sacrifice explained](/uk/financial-info/pension-salary-sacrifice). ## National Insurance vs Income Tax National Insurance and income tax are two separate deductions, even though both come out of your pay before you see your take-home. They have different thresholds, different rate structures, and fund different things. Income tax is progressive — the more you earn, the higher the rate on each additional slice — while Class 1 NI actually drops to a lower 2% rate once you pass the Upper Earnings Limit. They also respond differently to pension contributions: income tax is reduced by any qualifying pension contribution, but NI is only reduced when the contribution is made by salary sacrifice (which shrinks your NI-able pay). Both are withheld by your employer under PAYE and both reduce the gross salary before take-home, but the calculations behind them are independent. ## See National Insurance in Your Take-Home Pay National Insurance is one of the two headline deductions between your gross salary and your take-home pay — a banded charge that starts at the Primary Threshold and drops to 2% above the Upper Earnings Limit. To see exactly how NI and income tax combine on your salary, run your numbers through the UK Take-Home Pay Calculator below. It applies the verified 2026-27 rates, including the £12,570 Primary Threshold and £50,270 Upper Earnings Limit, so your take-home estimate matches what you'll actually see on your payslip. ## Related tools and guides - [UK Take-Home Pay Calculator](/uk/salary-calculator) — see NI and income tax on your salary - [UK Income Tax Bands & Personal Allowance](/uk/financial-info/income-tax-bands-personal-allowance) — the other big deduction between gross and take-home - [Pension Salary Sacrifice Explained](/uk/financial-info/pension-salary-sacrifice) — how salary sacrifice lowers both NI and income tax - [How to Calculate Your UK Take-Home Pay](/uk/financial-info/how-to-calculate-take-home-pay) — the full workflow from gross to net This article is for general information purposes only and does not constitute tax or financial advice.
