Self-employed individuals primarily pay Class 2 and Class 4 NICs, while company directors pay Class 1 NICs like employees, but with some differences in timing and calculation.
Class 2 and Class 4 NICs for the Self-Employed
Class 2 NICs are fixed weekly contributions paid by self-employed people with profits above £12,570 in 2026/26. These contributions count towards your State Pension and other benefits.
Class 4 NICs are based on profits and are calculated as a percentage. You pay 9% on profits between £12,570 and £50,270, then 2% on profits above £50,270.
Class 1 NICs for Company Directors
Company directors pay Class 1 NICs through the PAYE system, similar to employees. However, because directors’ earnings can fluctuate, their NICs are often calculated on an annual basis rather than each pay period. This accounting adjustment ensures NICs reflect total annual earnings.
How to Pay National Insurance Contributions
For the self-employed, NI contributions are usually paid through the Self Assessment tax return system. HMRC calculates your Class 2 and Class 4 NICs based on your declared profits, and you pay these alongside your income tax bill.
Company directors’ NICs are deducted automatically via PAYE by their company. Directors must ensure their company runs payroll correctly and submits Real Time Information (RTI) to HMRC on time.

NI Rates and Thresholds for 2026/26
The thresholds and rates for National Insurance are set by HM Treasury and updated annually. For 2026/27, the key figures relevant to the self-employed and company directors are:
- Small Profits Threshold (Class 2): £12,570 per year
- Lower Profits Limit (Class 4): £12,570 per year
- Upper Profits Limit (Class 4): £50,270 per year
- Class 2 rate: £3.45 per week
- Class 4 rates: 9% between £12,570 and £50,270; 2% above £50,270
- Class 1 Primary Threshold (Company Directors): £12,570 per year
- Class 1 Upper Earnings Limit: £50,270 per year
- Class 1 rates: 12% between £12,570 and £50,270; 2% above £50,270
Note that the Small Profits Threshold means if your self-employed profits are below £12,570, you do not have to pay Class 2 NICs but can choose to pay voluntarily to maintain your benefit record.
How NI Contributions Affect Your State Pension and Benefits
Paying National Insurance contributions builds your entitlement to various state benefits, most notably the State Pension. To qualify for the full new State Pension, you need 35 qualifying years of NI contributions or credits.
If your self-employed profits are low or you are between jobs, you may be eligible for NI credits that protect your benefit record. Voluntary NI payments are also an option if you have gaps.
Benefits of Maintaining Your NI Record
- State Pension: Full entitlement requires 35 qualifying years.
- Contribution-based Jobseeker’s Allowance: Requires sufficient NI contributions.
- Maternity Allowance: Based on NI contributions.
- Bereavement Support Payment: Dependent on a partner’s NI record.
For directors, paying Class 1 NICs through PAYE ensures their NI record is maintained automatically.
Voluntary National Insurance Payments
If you have gaps in your NI record—due to low profits or periods of unemployment—you may want to consider making voluntary NI payments. This can help you qualify for the full State Pension or other benefits.
Self-employed individuals can pay Class 2 voluntarily if their profits fall below the Small Profits Threshold. Alternatively, Class 3 voluntary contributions may be an option to fill gaps, but these are generally more expensive.
Check your NI record via the GOV.UK NI record service and consult HMRC or a financial adviser before making voluntary payments.
Key Steps to Manage Your National Insurance Contributions
- Register with HMRC: Ensure you are registered as self-employed or as a company director to receive your NI number and set up your tax records.
- Keep accurate profit records: For self-employed, maintain clear accounts to calculate Class 2 and Class 4 NICs correctly.
- Submit Self Assessment on time: Pay your Class 2 and Class 4 NICs alongside income tax by 31 January following the end of the tax year.
- For company directors: Ensure payroll is run correctly, with NICs deducted via PAYE and RTI submissions made on schedule.
- Review your NI record annually: Use GOV.UK tools to check your contributions and consider voluntary payments if you have gaps.
- Seek professional advice: For complex situations, consult an accountant or tax adviser to optimise your NI and tax position.
- Self-employed individuals pay Class 2 (£3.45/week) and Class 4 (9% and 2%) NI based on profits over £12,570.
- Company directors pay Class 1 NICs via PAYE, with rates of 12% and 2% based on earnings thresholds.
- NI contributions build entitlement to the State Pension and other benefits; 35 qualifying years are needed for the full new State Pension.
- You can make voluntary NI payments to fill gaps in your record and maintain benefit eligibility.
- Timely Self Assessment filing and accurate payroll are essential to avoid penalties and ensure correct NI contributions.

Company directors pay Class 1 National Insurance contributions through their company’s payroll under the PAYE system. Contributions are usually calculated annually to reflect total earnings and deducted accordingly.
Can I make voluntary National Insurance payments to protect my State Pension?
Yes, if you have gaps in your NI record, you can make voluntary Class 2 or Class 3 contributions to maintain your entitlement to the full State Pension. Check your NI record online and consider professional advice before paying.
