By Chandraketu Tripathi · Updated April 2026 · Fact-checked Tax · April 2026National Insurance (NI) contributions are paid by workers and employers to fund the State Pension, NHS and certain other state benefits. The rates and thresholds for 2026/27 are largely unchanged from 2025/26 — but with wages rising and thresholds frozen, more workers are paying NI on a larger proportion of their earnings each year.
Employee National Insurance — What You PayEmployees pay Class 1 National Insurance contributions at 8% on earnings between the Primary Threshold (£12,570/year) and the Upper Earnings Limit (£50,270/year). Above £50,270, the rate drops to 2%. NI is calculated weekly or monthly based on pay period — not annually. This means workers with variable income can sometimes pay different amounts than a simple annual calculation suggests. A worker earning £35,000 per year pays approximately £1,786 in employee NI contributions — equivalent to about 5.1% of gross income. Combined with income tax of approximately £4,486, the total deduction on £35,000 is approximately £6,272, leaving a net take-home of approximately £28,728. Employer NI — The April 2025 Change Still in EffectThe employer NI rate rose from 13.8% to 15% in April 2025, and the secondary threshold dropped from £9,100 to £5,000 per year. This means employers now pay 15% NI on all employee earnings above £5,000 — significantly increasing employment costs for many businesses. This change remains in place for 2026/27. NI and Your State PensionEvery year you pay sufficient National Insurance contributions counts as a 'qualifying year' toward your State Pension entitlement. You need 35 qualifying years for the full new State Pension (£241.05/week from April 2026) and at least 10 years for any State Pension. Check your NI record at gov.uk/check-national-insurance-record to see your qualifying years and identify any gaps. 💡 Voluntary Class 3 NI contributions cost approximately £824 per qualifying year and add approximately £357 to your annual State Pension — a payback period of under 2.5 years. If you have gaps in your NI record, filling them is one of the highest-return financial decisions available. Check the current deadline for backdating voluntary contributions at gov.uk. ⭐ OUR VERDICT National Insurance thresholds remain frozen in 2026/27, meaning workers are paying NI on a larger proportion of their earnings as wages rise — the same fiscal drag affecting income tax. The key actions for workers: check your NI record annually for gaps, consider salary sacrifice into pensions (reduces both income tax and employee NI), and if self-employed, ensure Class 4 NI is correctly calculated on your Self Assessment return. Frequently Asked QuestionsWhat is the National Insurance rate in 2026? Employees pay 8% National Insurance on earnings between £12,570 and £50,270 per year, and 2% on earnings above £50,270. Employers pay 15% on employee earnings above £5,000 per year (unchanged from the April 2025 increase). Self-employed pay Class 4 NI at 6% on profits between £12,570 and £50,270, and 2% above. Does National Insurance affect my State Pension? Yes. Each year you pay sufficient National Insurance contributions counts as a qualifying year toward your State Pension. You need 35 qualifying years for the full new State Pension and at least 10 years for any entitlement. You can fill gaps by paying voluntary Class 3 contributions at approximately £824 per year. Do I pay National Insurance on pension income? No. National Insurance is not payable on pension income — neither State Pension nor private pension income attracts NI contributions. NI is only payable on earned income from employment or self-employment, up to State Pension age. What is the employer NI threshold in 2026? From April 2025 (still applying in 2026/27), employers pay 15% National Insurance on employee earnings above £5,000 per year — down from the previous £9,100 threshold. The Employment Allowance (which reduces employer NI bills) increased to £10,500 per year for eligible employers. |
