U.K. employee, employer, and self-employed contributions, including 2026-27 rates, qualifying records, voluntary payments, and worked examples.
National Insurance is the U.K. system of statutory contributions paid by employees, employers, self-employed people, and eligible voluntary contributors, together with credits that can protect a person’s contribution record. The amount paid depends on employment status, earnings or profits, contribution class, category letter, and tax year. The resulting contribution and credit record can help establish entitlement to the State Pension and certain contributory benefits.
National Insurance has two financial effects that should not be confused. It can reduce a worker’s take-home pay or increase an employer’s payroll cost, while a person’s contribution and credit history can also affect benefit entitlement. Paying more in one pay period does not create a personal investment balance or guarantee a particular benefit amount.
For an employee, National Insurance affects net pay. For an employer, it affects the total cost of employment. For a self-employed person, it can affect Self Assessment liabilities. For someone planning retirement, the record can affect State Pension entitlement and may influence whether a voluntary contribution is useful.
The system therefore appears in several records:
The relevant record depends on the question. A payslip answers what was deducted from one payment. A National Insurance record answers whether a year contains contributions or credits. A State Pension forecast estimates the effect of that history under pension rules.
| Class | Main person responsible | General purpose |
|---|---|---|
| Class 1 employee | Employees below State Pension age; a cash contribution starts above the primary threshold | Payroll contribution that can count toward specified pensions and benefits |
| Class 1 employer | Employers | Separate payroll cost based on employee category and earnings |
| Class 1A and 1B | Employers | Contributions on specified employee expenses, benefits, and certain settlements |
| Class 2 | Eligible self-employed people | Can protect entitlement to the State Pension and specified contributory benefits; may be treated as paid or paid voluntarily |
| Class 3 | Eligible voluntary contributors | Used to fill or avoid qualifying-record gaps, principally for State Pension purposes |
| Class 4 | Self-employed people with profits above the threshold | Profit-based contribution that does not itself count toward state pensions or contributory benefits |
The class alone does not establish the amount. Employee and employer Class 1 calculations also use a category letter, and special rules can apply to directors, workers with multiple jobs, people working abroad, landlords, share fishermen, and other groups.
For a typical employee in category A, the weekly employee rates from April 6, 2026 through April 5, 2027 are:
| Weekly earnings band | Employee category A rate |
|---|---|
| Below GBP 129 | No employee contribution; voluntary Class 3 may be relevant if there is a record gap |
| GBP 129 to GBP 242 | 0%; the earnings can still support a qualifying record and certain benefits |
| GBP 242.01 to GBP 967 | 8% |
| Above GBP 967 | 2% on the slice above GBP 967 |
The 8% and 2% rates apply to different slices of earnings. The 2% rate above the upper earnings limit does not replace the 8% already calculated on the middle band.
Monthly payroll uses corresponding monthly thresholds. Other pay intervals and director calculations can use different mechanics, so multiplying one weekly result by 52 will not reproduce every payroll outcome.
Assume a category A employee earns GBP 1,000 in one week in 2026-27.
The first GBP 242 produces no employee contribution.
(GBP 967 - GBP 242) x 8% = GBP 58.00
The remaining GBP 33 is above the upper earnings limit:
(GBP 1,000 - GBP 967) x 2% = GBP 0.66
Total employee National Insurance for the week is:
GBP 58.00 + GBP 0.66 = GBP 58.66
This is the official category A example structure. It does not account for another category letter, multiple employments, director rules, corrections, or payroll rounding outside the stated facts.
Employer National Insurance is separate from the amount deducted from an employee’s pay. It is an employer payroll cost.
For a category A employee in 2026-27, the ordinary employer rate is 15% on weekly earnings above the GBP 96 secondary threshold. Using the same GBP 1,000 weekly earnings:
(GBP 1,000 - GBP 96) x 15% = GBP 135.60
The employee contributes GBP 58.66 under the example, while the employer separately contributes GBP 135.60 before any applicable relief or adjustment. Adding the employer amount to the employee deduction would incorrectly overstate the employee’s payroll deduction.
Employer category letters and reliefs matter. Certain apprentices, employees under specified ages, veterans, and freeport or investment-zone employees can have different employer rate bands. The Employment Allowance can also reduce an eligible employer’s overall liability but does not change the employee’s recorded deduction.
Class 1A and Class 1B employer contributions are generally 15% for 2026-27 on amounts within those classes. These cover specified benefits, expenses, or PAYE Settlement Agreement items rather than ordinary cash salary.
Self-employed treatment separates contribution-record protection from the profit-based Class 4 charge.
For 2026-27:
An eligible self-employed person with profits below GBP 7,105 can choose to pay voluntary Class 2 contributions at GBP 3.65 per week for 2026-27. Special occupational and overseas rules can change eligibility.
Assume taxable self-employed profits of GBP 60,000 for 2026-27 and no special adjustments.
First band:
(GBP 50,270 - GBP 12,570) x 6% = GBP 2,262.00
Upper band:
(GBP 60,000 - GBP 50,270) x 2% = GBP 194.60
Total simplified Class 4 liability:
GBP 2,262.00 + GBP 194.60 = GBP 2,456.60
The Class 4 payment does not create State Pension entitlement. In this example, Class 2 treatment protects the contribution record because profits exceed the Small Profits Threshold. A real Self Assessment result can differ because taxable profits, loss rules, accounting periods, multiple activities, employment income, and other adjustments matter.
Someone who is both employed and self-employed can have Class 1 payroll deductions and Class 4 liability. HMRC applies rules for the combined position after the Self Assessment return is filed.
National Insurance credits can protect a person’s contribution record during specified periods when they are not paying contributions through work. Depending on the rules, credits may be available in situations involving caring, illness, disability, unemployment, parental benefits, or other qualifying circumstances.
A credit is not cash paid to the claimant. It is an entry on the National Insurance record. Different credits can protect different benefits, and some require a claim rather than appearing automatically.
This distinction explains why two people with the same cash contributions can have different qualifying records, or why a person can build a qualifying year without paying employee contributions. The official record, not a rough sum of deductions, controls the analysis.
Contribution class affects which benefits can use the record.
GOV.UK identifies Class 1, Class 2, and Class 3 as counting toward the new State Pension. Class 1 can also support specified contribution-based benefits. Class 2 can support a narrower set of contributory benefits. Class 3 is mainly used to improve State Pension entitlement.
Class 4 is different: it is a contribution liability on self-employed profits but does not count toward state benefits or pensions.
National Insurance contributions are paid into the statutory system, not allocated to an individual investment account. Legislation also provides for an NHS allocation from certain contributions, but it is inaccurate to treat a worker’s entire deduction as a personal NHS premium or as money reserved exclusively for that worker’s future benefits.
The GOV.UK record service can show:
Check the record against payslips, P60 forms, Self Assessment records, benefit or credit notices, and periods spent outside the U.K. A missing year can result from reporting timing, low earnings, an unclaimed credit, or an actual contribution gap.
A State Pension forecast is a separate check. It estimates the pension under current rules and can show whether additional qualifying years may increase the amount. The forecast can be more decision-relevant than the simple number of complete years because pre-2016 records, contracting-out history, and the maximum pension can affect the result.
Voluntary contributions may fill certain record gaps, but payment is not automatically worthwhile.
For 2026-27, the standard voluntary rates are:
| Voluntary class | Weekly rate | Indicative 52-week cost | Typical role |
|---|---|---|---|
| Class 2 | GBP 3.65 | GBP 189.80 | Available only to eligible people, including some people with low self-employed profits |
| Class 3 | GBP 18.40 | GBP 956.80 | Broader voluntary route, generally for State Pension record gaps |
Before paying, confirm:
Special restrictions apply to contributions for periods abroad, including changes effective from 2026-27. Someone with overseas work or residence should use the current official eligibility rules rather than assume older Class 2 or Class 3 access continues.
| Feature | National Insurance | Income Tax |
|---|---|---|
| Main base | Employee earnings, employer payroll amounts, self-employed profits, or specified benefits and expenses | Taxable income after applicable allowances and reliefs |
| Main payers | Employees, employers, self-employed people, and voluntary contributors | Individuals and other taxable persons; employers withhold employee tax through PAYE |
| Typical employee calculation | Earnings bands in each pay period, subject to category and special rules | PAYE uses tax codes and cumulative or non-cumulative rules |
| Record effect | Some classes and credits can support State Pension and contributory-benefit entitlement | Paying more Income Tax does not by itself create a State Pension qualifying year |
| State Pension age | Employee contributions generally stop when the worker reaches State Pension age; employer contributions can continue | Employment income can remain taxable after State Pension age |
| Self-employed treatment | Class 4 uses profit bands; Class 2 may protect the record | Income Tax applies to taxable profits under separate bands and allowances |
National Insurance and Income Tax can both appear on the same payroll or Self Assessment calculation, but they are separate liabilities with different thresholds and consequences.
An employer should forecast gross salary, employer National Insurance, pension contributions, benefits, and other payroll costs separately. Salary alone understates the cost of employing a worker.
An employee or self-employed household should separate:
National Insurance rates can change take-home pay even when the contractual salary is unchanged. For a household receiving Universal Credit, the resulting net earnings and pay-period timing can also affect the monthly benefit calculation.
