Who pays National Insurance, and which class?

This National Insurance contributions FAQ starts with the basics: National Insurance contributions are the UK payments that build your entitlement to certain state benefits, including the State Pension. official UK government guidance says how much you pay depends on your employment status and how much you earn, and for most employees it is taken from wages automatically before you are paid.

For the 2026 to 2027 tax year, from 6 April 2026 to 5 April 2027, most employees pay Class 1 contributions of 8% on pay between £242 and £967 a week (£1,048 to £4,189 a month) and 2% on pay above £967 a week. Self-employed people with profits above £12,570 pay Class 4 contributions of 6% on profits up to £50,270 and 2% above that.

Employees pay Class 1 National Insurance. Their employer deducts it through payroll along with income tax, and the payslip shows the contributions. A director of a limited company may also be their own employee and pay Class 1 through PAYE payroll.

Self-employed people whose profits are more than £12,570 a year pay Class 4 contributions. Most people pay Class 2 and Class 4 through Self Assessment. official UK government guidance notes one exception: examiners, moderators, invigilators and people who set exam questions cannot pay Class 4 through Self Assessment and must contact HMRC to arrange payment.

If you are an employee and also do self-employed work, your employer deducts Class 1 from your wages and you may also owe Class 4 on your self-employed profits. HMRC tells you how much is due after you file your Self Assessment return. Separate rules apply to company directors, landlords running a property business and share fishermen.

Some people pay less: official UK government guidance lists married women or widows with a valid certificate of election, and people deferring National Insurance because they have more than one job.

Readers evaluating National Insurance contributions should separate marketing claims from the actual rule text that governs their account or product. When two summaries disagree, the governing document or statute wins. If a rule depends on your age, filing status, or income band, re-check it when any of those facts change. Life events quietly move people across thresholds they last reviewed years earlier.

Educational explainers like this one cannot replace personalized advice for complex situations such as divorce orders, inherited accounts, or cross-border tax residency. Escalate those cases to a qualified professional. When in doubt about a number that changes every year, describe your plan qualitatively first, then look up the current official figure for the tax year you care about before you act.

How do the 2026 to 2027 employee bands work?

For category letter A, which covers most employees, official UK government guidance's table shows 0% on weekly earnings from £129 to £242, 8% on £242.01 to £967, and 2% on earnings over £967. Earnings between £129 and £242 a week still count toward your record even though no contribution is deducted.

official UK government guidance gives a worked example: a category A employee earning £1,000 in a week pays nothing on the first £242, 8% (£58) on earnings between £242.01 and £967, and 2% (£0.66) on the remaining earnings above £967, a total of £58.66 for the week.

Other category letters have different rates. For example, categories B, E and I show 1.85% in the main band, while categories D, J, L and Z show 2%. Your letter appears on your payslip, and employers choose it based on your circumstances. You can rough out take-home pay with the calculators at

A useful habit is to write down your goal, time horizon, and cash buffer before you change any election related to National Insurance contributions. Decisions made during a stressful week are the ones people reverse later at a cost.

Escalate those cases to a qualified professional.

Compare fees the same way you would compare two similar listings before you buy: look at what you pay each year, what you get, and whether a simpler option meets the same need. Readers evaluating National Insurance contributions should separate marketing claims from the actual rule text that governs their account or product. When two summaries disagree, the governing document or statute wins.

What do employers and the self-employed pay?

Employers pay their own share on top of your wages. For 2026 to 2027, official UK government guidance's employer table shows a 15% rate for category A on weekly earnings above £96 (£417 a month). Some categories, such as those for younger workers or apprentices, have 0% employer rates up to £967 a week. Employers also pay Class 1A and 1B contributions on expenses and benefits at 15% for the year.

For the self-employed, the 2026 to 2027 Class 4 rates are 6% on profits over £12,570 up to £50,270 and 2% on profits over £50,270. Worked example: with profits of £30,000, Class 4 would be 6% of £17,430 (the part above £12,570), which is £1,045.80.

Class 2 contributions are now something you may choose to pay. official UK government guidance sets the Class 2 rate for 2026 to 2027 at £3.65 a week. Paying voluntarily can help fill your record if your profits are low, so it is worth checking before deciding.

Keep digital and paper copies of confirmations after every change. Screenshots of election pages, email receipts, and year-end statements make tax season and job changes far less chaotic. Compare fees the same way you would compare two similar listings before you buy: look at what you pay each year, what you get, and whether a simpler option meets the same need.

Why your National Insurance record matters

Contributions build qualifying years on your record. If your National Insurance record started after April 2016, official UK government guidance says you will need 35 qualifying years to get the full rate of new State Pension, and you need 10 qualifying years to get any new State Pension at all. People who were contracted out usually need more than 35 years for the full rate.

You can check your record and apply for a refund if you think you have overpaid. Gaps can sometimes be filled with voluntary contributions; HMRC's guidance explains the deadlines and costs for your situation.

A practical tip for first-timers: your National Insurance number stays the same for life, so keep it safe and give it only to your employer, HMRC, your pension provider and other official bodies that need it. When starting a new job, make sure your employer has the right number, otherwise contributions may not be credited to your record correctly. If you change jobs mid-year, compare your payslips to confirm deductions continued and that your category letter still fits your circumstances.

Next steps: check your category letter on your payslip, confirm your record online, and, if self-employed, set aside money for Class 4 when you file. For more UK money explainers see and

If a rule depends on your age, filing status, or income band, re-check it when any of those facts change. Life events quietly move people across thresholds they last reviewed years earlier. Automation helps. Calendar reminders for annual reviews, automatic transfers, and beneficiary checkups reduce the chance that a good plan dies from neglect.
