What Is National Insurance and Why Does It Matter

National Insurance (NI) is a tax on earnings that funds the UK’s State Pension, as well as benefits like Statutory Sick Pay, Maternity Allowance, and Jobseeker’s Allowance.National Insurance Rates Unlike Income Tax, which applies to almost every type of income, National Insurance only applies to money you earn from working — your salary, wages, or self-employed profits National Insurance Rates.

This is an important distinction.National Insurance Rates Rental income, dividends, savings interest, and pension income are not subject to National Insurance, which is one reason people with investment income often end up with a lower overall NI bill than someone earning the same amount purely from a salary National Insurance Rates.

Paying National Insurance also builds your entitlement to the State Pension. National Insurance Rates Miss too many years of contributions, and you could end up with a smaller pension when you retire — which is why understanding your NI record matters just as much as understanding the rate you’re paying today.

Here’s a quick summary table before we go into detail:

NI Type	Who Pays It	Rate 2026/27
Class 1 (Employee)	Employees	8% between £12,570–£50,270, 2% above £50,270
Class 1 (Employer)	Employers	15% on earnings above £5,000 per year

Nothing has changed for employee or self-employed rates compared with 2025/26 — the government has kept these frozen. National Insurance Rates The bigger story this year is on the employer side, which we’ll cover below.

National Insurance Classes Explained

There isn’t just one type of National Insurance. National Insurance Rates Which class applies to you depends on whether you’re employed, self-employed, or making voluntary payments to protect your State Pension National Insurance Rates.

Class 1 – For Employees

If you’re employed, Class 1 National Insurance is deducted automatically from your salary before you’re paid. You don’t need to do anything — your employer calculates and pays it through PAYE (Pay As You Earn).

For 2026/27, employees pay:

• 0% on earnings up to £12,570 a year (the Primary Threshold)
• 8% on earnings between £12,570 and £50,270
• 2% on anything earned above £50,270

So if your salary rises, only the portion above these thresholds is taxed at the higher rate — you’re not suddenly charged 8% on your entire income.

Class 1 – For Employers

Employers also pay National Insurance on top of what they pay their staff. National Insurance Rates For 2026/27, the employer rate is 15% on earnings above £5,000 per year (known as the Secondary Threshold) National Insurance Rates.

This rate and threshold were set following changes introduced in late 2024, and they remain unchanged for 2026/27. National Insurance Rates It’s worth knowing about even if you’re an employee, because it directly affects how much it costs a business to hire — which can influence wage growth and hiring decisions National Insurance Rates.

There’s some relief available here too. National Insurance Rates The Employment Allowance, which lets eligible small employers reduce their NI bill, has increased to £10,500, and the previous £100,000 eligibility cap has been removed — meaning more businesses now qualify National Insurance Rates.

Class 2 – Self-Employed (Now Voluntary)

Class 2 NI used to be compulsory for self-employed people with profits above a set threshold. National Insurance Rates That’s no longer the case — it’s now voluntary. National Insurance Rates Some self-employed people choose to pay it anyway because it’s a relatively cheap way to keep their State Pension record intact, especially if their profits are low that year National Insurance Rates.

For 2026/27, the voluntary Class 2 rate is £3.65 per week.

Class 3 – Voluntary Contributions

Class 3 is for people who want to fill gaps in their National Insurance record — perhaps because they took time off work, lived abroad, or had low earnings in previous years. You typically need 35 qualifying years to get the full new State Pension, and unfilled gaps can permanently reduce what you receive.

A single Class 3 year costs roughly £946 for 2026/27. It sounds like a lot upfront, but it can add a meaningful amount to your annual State Pension for life, often paying for itself within a few years of retirement.

Class 4 – Self-Employed on Profits

If you’re self-employed, your main NI liability comes from Class 4 contributions, calculated on your yearly profits rather than your turnover.

For 2026/27:

• 0% on profits up to £12,570
• 6% on profits between £12,570 and £50,270
• 2% on profits above £50,270

Notice that the main rate here is 6%, compared to 8% for employees. This is one of the genuine financial differences between being employed and self-employed.

National Insurance Thresholds 2026/27 Explained

Thresholds decide where each rate kicks in. Here’s the full breakdown for 2026/27:

Threshold	Weekly	Monthly	Annual
Lower Earnings Limit (LEL)	£129	£559	£6,708
Primary Threshold (PT)	£242	£1,048	£12,570
Upper Earnings Limit (UEL)	£967	£4,189	£50,270
Secondary Threshold (employer)	£96	£417	£5,000

One detail people often miss: if you earn between the Lower Earnings Limit and the Primary Threshold, you pay no National Insurance, but you’re still treated as having paid it for State Pension purposes. In other words, you get the pension benefit at zero actual cost. Earn below the Lower Earnings Limit, though, and that year won’t count towards your record at all.

Also worth noting — most of these thresholds have been frozen since 2022 and are set to stay frozen until April 2028. As wages rise with inflation, more of your income gets pulled into the taxable band each year, a phenomenon often called “fiscal drag.” It’s not a rate rise, but it has a similar effect on your take-home pay over time.

How to Calculate Your National Insurance (Step by Step)

Working out your NI is more straightforward than it looks. Here’s the process for an employee:

1. Take your annual salary.
2. Subtract £12,570 (the Primary Threshold) — this is the portion that gets taxed.
3. If your salary is £50,270 or below, multiply that portion by 8%.
4. If your salary is above £50,270, apply 8% to the amount between £12,570 and £50,270, then apply 2% to everything above £50,270.
5. Add the two amounts together for your total annual NI.

Worked Example 1 — Salary of £25,000

• Taxable portion: £25,000 − £12,570 = £12,430
• NI due: £12,430 × 8% = £994.40 a year (around £83 a month)

Worked Example 2 — Salary of £35,000

• Taxable portion: £35,000 − £12,570 = £22,430
• NI due: £22,430 × 8% = £1,794.40 a year (around £150 a month)

Worked Example 3 — Salary of £60,000

• Band 1: £50,270 − £12,570 = £37,700 × 8% = £3,016
• Band 2: £60,000 − £50,270 = £9,730 × 2% = £194.60
• Total NI due: £3,210.60 a year

Worked Example 4 — Self-Employed Profit of £45,000

• Taxable profit: £45,000 − £12,570 = £32,430
• Class 4 NI: £32,430 × 6% = £1,945.80 a year

Worked Example 5 — Employer Cost on a £30,000 Salary

• Amount above Secondary Threshold: £30,000 − £5,000 = £25,000
• Employer NI: £25,000 × 15% = £3,750 a year

These examples show how quickly employer costs can add up compared to what an employee actually sees deducted from their own pay.

Employee vs Self-Employed: A Quick Comparison

Factor	Employee	Self-Employed
Main NI rate	8%	6%
Threshold	£12,570	£12,570
Upper rate	2% above £50,270	2% above £50,270
Who pays it	Deducted automatically by employer	Paid via Self Assessment
Employer contribution	Yes, employer pays extra 15%	Not applicable

The self-employed rate is lower, but self-employed workers don’t benefit from certain employer-funded protections, such as automatic pension contributions or statutory sick pay, so it’s not a straightforward like-for-like comparison.

National Insurance and the State Pension

Your NI record directly determines your State Pension entitlement. You generally need 35 qualifying years of contributions (or credits) to receive the full new State Pension, and at least 10 years to get anything at all.

If you have gaps — for example, from time spent unemployed, caring for children, or living overseas — voluntary Class 3 contributions are usually the way to fill them. It’s worth checking your NI record through your personal tax account periodically, especially if you’ve had breaks in employment, since gaps are much cheaper to fill sooner rather than later.

What Changed for 2026/27

The headline for most people is: not much changed on the employee side. The Primary Threshold, Upper Earnings Limit, and main employee/self-employed rates are all unchanged from 2025/26.

The notable updates are:

• The Lower Earnings Limit rose slightly to £129 a week (£6,708 a year), based on CPI indexation.
• Employer National Insurance remains at 15%, with the Secondary Threshold still at £5,000 — both figures carried over from the changes introduced in late 2024.
• The Employment Allowance increased to £10,500, and the previous eligibility cap of £100,000 in NI liability has been scrapped, opening it up to more employers.
• From April 2026, people working outside the UK are no longer able to pay Class 2 National Insurance voluntarily under the previous arrangements.

For employees, the practical effect is that thresholds staying frozen while wages rise means a growing share of income becomes taxable each year — even without any headline rate change.

Common National Insurance Mistakes to Avoid

• Assuming NI and Income Tax use the same allowance. They don’t. The Personal Allowance for Income Tax and the Primary Threshold for NI happen to align at £12,570, but they’re calculated separately.
• Forgetting about multiple jobs. Each employer applies NI thresholds separately, which can mean you pay more NI overall than someone earning the same total from one job. If this applies to you, you may be able to apply for deferment.
• Ignoring gaps in your NI record. Small gaps are cheap to fill now and expensive to fix later, especially close to retirement.
• Overlooking voluntary Class 2 or Class 3 contributions when self-employed income is low — sometimes a small voluntary payment protects a full qualifying year.

Final Thoughts

National Insurance can feel like a maze of thresholds and classes, but once you understand the basic structure — a tax-free slice, a main rate, and a lower rate above a certain point — the numbers become much easier to work with. For 2026/27, the key takeaway is that employee and self-employed rates haven’t moved, but frozen thresholds mean your NI bill can quietly creep up as your income grows.
