National Insurance Contributions for Self-Employed: 2026/27 Rates & How to Pay

Self-employed people in the UK generally pay Class 4 National Insurance contributions at 6% on annual taxable profits between £12,570 and £50,270, followed by 2% on profits above £50,270 during the 2026/27 tax year. Those earning less than £12,570 do not normally pay compulsory Class 4 National Insurance.

Class 2 contributions work differently. From April 2024, compulsory Class 2 payments were removed for most self-employed workers. In 2026/27, those earning at least £7,105 can have their Class 2 contributions treated as paid, protecting their National Insurance record without a separate payment.

Our analysis of the current HMRC framework shows that understanding the difference between turnover, taxable profit and National Insurance thresholds is essential for freelancers, sole traders, contractors and people earning money through side hustles.

This article examines the latest contribution rates, calculations, payment procedures, voluntary contributions, pension implications and practical financial planning for 2026/27.

What Are the National Insurance Contributions for Self-Employed People in 2026/27?

National Insurance contributions (NICs) are payments associated with employment earnings and self-employment profits. They help determine eligibility for certain state benefits and the State Pension.

For self-employed individuals, the two most relevant contribution categories are Class 2 and Class 4.

• Class 2 National Insurance: Supports entitlement to certain contributory benefits and the State Pension. Most qualifying self-employed people no longer make compulsory payments.
• Class 4 National Insurance: A compulsory contribution calculated on taxable self-employment profits above £12,570.

Employees usually pay Class 1 contributions through PAYE, while company directors generally follow employment-related National Insurance rules when receiving a salary.

Understanding these distinctions is important because registering as self-employed does not automatically mean National Insurance must be paid immediately.

Someone earning £8,000 in annual self-employed profits may have their Class 2 record protected without paying National Insurance. Another sole trader earning £40,000 will normally have a Class 4 liability.

The business structure, profit level and individual circumstances determine the treatment.

What Are the Self-Employed National Insurance Rates for 2026/27?

The 2026/27 tax year runs from 6 April 2026 to 5 April 2027.

HMRC has confirmed the following rates and profit thresholds.

The key distinction is that the 6% rate applies only to profits above £12,570 and up to £50,270. The 2% rate applies to profits above £50,270.

For example, a freelancer making £30,000 in taxable business profit does not pay 6% on the entire £30,000.

Instead, the first £12,570 attracts no Class 4 contribution, while the remaining £17,430 is charged at 6%.

HMRC’s official National Insurance rates confirm the £7,105 Small Profits Threshold, £12,570 Class 4 Lower Profits Limit and the 6% and 2% contribution bands for 2026/27.

The official table is particularly useful because it distinguishes the Class 2 contribution threshold from the point where Class 4 becomes payable.

How Does Class 2 National Insurance Work for Self-Employed People?

Class 2 National Insurance has undergone significant changes.

Before April 2024, most self-employed people paid a fixed weekly Class 2 contribution when their profits exceeded the applicable threshold.

The government removed the requirement for compulsory Class 2 payments for most self-employed people from 6 April 2024.

However, Class 2 has not been completely abolished.

It continues to matter for voluntary payments, National Insurance records and certain categories of workers.

Profits Below £7,105

Individuals earning less than £7,105 in annual self-employed profits do not normally pay compulsory Class 2 or Class 4 National Insurance.

They may choose to pay voluntary Class 2 contributions if eligible.

For 2026/27, the weekly contribution is £3.65.

A full 52 weeks would cost:

£3.65 × 52 = £189.80

Voluntary payments may be useful where an individual would otherwise have a gap in their National Insurance record.

However, paying is not automatically worthwhile. Someone who already has a qualifying year through employment or National Insurance credits may not benefit.

Profits Between £7,105 and £12,570

Self-employed individuals whose profits reach £7,105 but do not exceed £12,570 normally receive Class 2 treatment without making an actual payment.

This means:

• No compulsory Class 2 payment is collected.
• Class 2 contributions are treated as paid.
• No Class 4 National Insurance is due.
• The person’s National Insurance record can be protected.

Our assessment is that this distinction is particularly important for part-time freelancers and individuals gradually developing a small business.

They may be building State Pension entitlement even where their profits are insufficient to trigger a compulsory National Insurance payment.

Profits Above £12,570

When annual taxable profits exceed £12,570, Class 4 National Insurance generally becomes payable.

Class 2 continues to be treated as paid, without a separate compulsory contribution for most workers.

This means a sole trader making £35,000 normally pays Class 4 contributions but does not additionally pay a compulsory weekly Class 2 amount.

How Much Class 4 National Insurance Do Self-Employed People Pay?

Class 4 National Insurance is calculated using annual taxable self-employment profits.

The standard calculation has three bands:

The 2% rate does not replace the 6% charge on profits in the lower band.

Example 1: Self-Employed Profit of £20,000

Annual taxable profit: £20,000

Profit above £12,570:

£20,000 − £12,570 = £7,430

Class 4 calculation:

£7,430 × 6% = £445.80

Annual Class 4 contribution: £445.80

Example 2: Self-Employed Profit of £40,000

Annual taxable profit: £40,000

Profit subject to the main rate:

£40,000 − £12,570 = £27,430

National Insurance:

£27,430 × 6% = £1,645.80

Annual Class 4 contribution: £1,645.80

Example 3: Self-Employed Profit of £60,000

This calculation requires both contribution rates.

First, calculate the amount within the main band:

£50,270 − £12,570 = £37,700

£37,700 × 6% = £2,262

Next, calculate the profit above £50,270:

£60,000 − £50,270 = £9,730

£9,730 × 2% = £194.60

Total:

£2,262 + £194.60 = £2,456.60

Annual Class 4 contribution: £2,456.60

These calculations are illustrative and assume standard circumstances without special National Insurance adjustments.

How Much National Insurance Is Payable on Different Self-Employed Profits?

Our calculations show how Class 4 contributions change as annual business profits increase.

The effective percentage is the total Class 4 contribution divided by annual taxable profit. It is not the statutory marginal rate and excludes Income Tax and other deductions.

An interesting finding from our calculations is that the effective Class 4 contribution percentage does not continue rising indefinitely.

At £50,270, the effective Class 4 rate is approximately 4.50% of total profit.

At £100,000, it falls to approximately 3.26%.

This happens because profits above £50,270 attract the lower marginal rate of 2%.

However, higher-income self-employed workers may still face substantially larger Income Tax liabilities.

The reduction in the effective Class 4 percentage should not be interpreted as a reduction in the overall tax burden.

Is Self-Employed National Insurance Calculated on Turnover or Profit?

National Insurance is generally calculated on taxable business profit, not turnover.

Turnover represents the total amount earned by a business before deducting expenses.

Profit is what remains after allowable business costs and relevant tax adjustments have been deducted.

Consider a freelance consultant with the following annual financial position.

Without considering expenses, the consultant might incorrectly calculate National Insurance using £55,000.

That would overstate the contribution liability.

Allowable business expenditure can therefore materially affect the amount of National Insurance payable.

Typical expenses may include business software, professional insurance, qualifying travel, equipment, advertising, stock and accountancy costs.

The precise treatment depends on the expense and the accounting method used.

Understanding what expenses can be claimed as self-employed is an important part of calculating taxable profit accurately.

Personal expenditure and money withdrawn from the business for private use are not normally deductible business expenses.

Does the £1,000 Trading Allowance Affect National Insurance?

Yes. The trading allowance can affect taxable business profit and, consequently, National Insurance calculations.

The UK provides a trading allowance of up to £1,000 for eligible trading and miscellaneous income.

Where qualifying annual gross trading income is no more than £1,000, the individual may not need to report it to HMRC, although exceptions apply.

For qualifying income above £1,000, a trader may be able to deduct either:

• Actual allowable business expenses.
• The £1,000 trading allowance.

Both cannot normally be claimed against the same income.

For example, consider a person earning £18,000 from freelance services.

If actual allowable expenses total £4,000, taxable profit would generally be £14,000.

Class 4 National Insurance would be:

£14,000 − £12,570 = £1,430

£1,430 × 6% = £85.80

If the person instead claimed the £1,000 trading allowance, taxable profit would be £17,000, producing a higher National Insurance liability.

Therefore, comparing the trading allowance with actual expenses can be financially important.

There are also restrictions on who can use the allowance, including certain partnership and connected-party income.

The £1,000 trading allowance rules explain the distinction between the reporting threshold, taxable profit and eligible deductions.

Do People With Side Hustles Pay National Insurance?

People earning additional income through side hustles may need to pay National Insurance if their activity amounts to self-employment and their taxable profits exceed the relevant threshold.

Examples include:

• Freelance writing and graphic design.
• Online tutoring and consulting.
• Delivering food as a self-employed courier.
• Selling handmade products.
• Professional photography.
• Website development.
• Dog walking and cleaning services.

However, earning additional income does not automatically create a National Insurance liability.

Example: An Employee With £5,000 in Side-Hustle Profit

Consider an employee earning £30,000 annually through PAYE who also makes £5,000 in taxable profit from freelance work.

The employee normally pays Class 1 National Insurance through their employment.

Their £5,000 self-employed profit is below the Class 4 Lower Profits Limit of £12,570.

Therefore, no Class 4 contribution would normally arise on that freelance profit.

However, the additional £5,000 may still create an Income Tax liability because the employee’s Personal Allowance is likely already being used against employment earnings.

The person may also need to submit a Self Assessment return.

This illustrates an important difference between Income Tax and National Insurance.

For people developing additional income streams, understanding the wider UK side-hustle landscape can help identify the tax and administrative requirements that accompany different earning activities.

Someone unsure whether their additional income must be reported should also check how to declare side-hustle income to HMRC before their filing deadline.

What Happens When Someone Is Both Employed and Self-Employed?

An individual can earn money through PAYE employment while independently operating a business.

In this situation, both Class 1 and Class 4 National Insurance rules may be relevant.

Class 1 contributions are generally deducted from employment earnings by the employer.

Class 4 contributions are calculated separately on taxable self-employment profits.

For example:

The individual does not normally combine salary and self-employment profit to calculate a single Class 4 figure.

However, special annual maximum rules may affect the final liability where someone pays both Class 1 and Class 4 contributions.

HMRC can calculate relevant adjustments through Self Assessment.

Our assessment is that people holding senior employment positions while operating consulting businesses should pay particular attention to these rules.

Assuming that National Insurance deducted from employment automatically eliminates Class 4 liability is incorrect.

How Can Self-Employed People Pay National Insurance to HMRC?

Most self-employed individuals pay Class 4 National Insurance through Self Assessment.

The process involves reporting business profits, calculating the applicable liability and paying HMRC by the relevant deadline.

Step 1: Register as Self-Employed

A person starting a business may need to register with HMRC and enter Self Assessment.

For the 2026/27 tax year, the normal registration deadline for someone newly required to submit a tax return is 5 October 2027.

Registration generally requires personal information, a National Insurance number, business details and the date self-employment began.

Anyone unfamiliar with the process can follow the requirements for registering as a sole trader in the UK before submitting their first tax return.

Step 2: Calculate Annual Business Profit

Calculate the amount earned through self-employment during the relevant accounting period.

Deduct allowable expenditure or apply an eligible allowance.

Keep records supporting the final figure.

Step 3: Complete the Self Assessment Return

Declare self-employment income, expenses and taxable profit using the relevant Self Assessment process.

HMRC calculates the Class 4 contribution alongside other liabilities.

People within Making Tax Digital must follow its software-based reporting procedures.

Step 4: Review the National Insurance Calculation

Check whether the correct thresholds and rates have been applied.

Where profits exceed £12,570, Class 4 will normally appear in the calculation.

Individuals with employment income, more than one business or special contribution arrangements may require additional adjustments.

Step 5: Pay the Amount Owed

Payment can normally be made using HMRC’s supported methods, including online banking and other authorised payment services.

The normal deadline for paying the 2026/27 balancing liability is 31 January 2028.

Self-employed workers should retain evidence of their tax return, calculation and payment.

What Are the Self Assessment Deadlines for 2026/27?

National Insurance liabilities are normally settled through the annual Self Assessment system.

The principal dates are:

These are the standard deadlines. Individuals should follow any applicable HMRC notices or special arrangements.

For the preceding 2025/26 tax year, the ordinary registration deadline was 5 October 2026 and the online filing deadline is 31 January 2027.

Anyone who has missed a registration deadline should contact HMRC promptly rather than waiting for the next filing period.

Do Payments on Account Include Class 4 National Insurance?

Yes. Class 4 National Insurance can form part of Self Assessment payments on account.

These payments are advance contributions towards the following tax year’s liability.

Where required, each payment is normally calculated as 50% of the previous year’s relevant Income Tax and Class 4 liability.

Consider a newly self-employed person with a 2026/27 Income Tax and Class 4 bill of £5,000.

Assuming no previous payments on account and that the standard requirements apply:

The initial January payment may therefore be significantly higher than the liability for the completed tax year alone.

Payments on account are not always required.

They generally do not apply when the previous relevant liability was less than £1,000 or when more than 80% of the tax was already collected outside Self Assessment.

The precise position depends on the individual’s circumstances.

From a cash-flow perspective, our analysis suggests that anticipating payments on account is just as important as calculating the annual National Insurance charge itself.

Do Self-Employed National Insurance Contributions Count Towards the State Pension?

Class 2 contributions can help protect entitlement to the State Pension and certain contributory benefits.

Class 4 contributions do not directly build State Pension entitlement.

This distinction is frequently misunderstood.

A self-employed person earning £60,000 could pay more than £2,400 in Class 4 contributions, but paying that amount does not create a larger State Pension entitlement than would arise from a qualifying Class 2 record.

State Pension entitlement depends on the person’s wider National Insurance record and qualifying years.

Someone with profits of £8,000 may have Class 2 treated as paid, helping them secure a qualifying year without making an actual contribution.

In contrast, a person earning £5,000 may need to consider voluntary Class 2 contributions if they have no other qualifying contributions or credits.

The financial value depends on the person’s existing record and the likely effect on their future pension.

Should Self-Employed People Pay Voluntary Class 2 Contributions?

Voluntary Class 2 contributions may be beneficial for eligible individuals whose annual profits fall below £7,105.

At £3.65 per week, a full year’s payments would amount to approximately £189.80.

For comparison, the standard voluntary Class 3 rate in 2026/27 is £18.40 per week.

A full 52-week period at the Class 3 rate would cost £956.80.

Class 2 can therefore be substantially less expensive, but it is only available where the individual meets the eligibility rules.

The relevant class is not a free choice between two prices.

Before paying voluntary contributions, individuals should establish whether:

• Their National Insurance record contains a gap.
• They are eligible to fill the relevant year.
• Employment contributions or credits already provide a qualifying year.
• Additional contributions would improve their State Pension.
• HMRC permits voluntary Class 2 payments for the period concerned.

The safest approach is to check the National Insurance record on GOV.UK and review the State Pension forecast before making any payment.

People considering voluntary contributions to qualify for benefits should also check the specific eligibility rules.

What Happens When Self-Employed People Make a Loss?

A self-employed person whose business makes a taxable loss generally has no Class 4 liability arising from that loss-making trade for the year.

For example, suppose a newly established business reports:

However, the loss does not automatically create a qualifying National Insurance year.

The individual may need to consider Class 2 contributions or other qualifying arrangements.

Loss relief can become more complicated where an individual operates several businesses or carries losses forward.

Certain losses may reduce future Class 4 profits from the same trade, subject to the relevant rules.

This makes accurate loss records important even when no immediate National Insurance payment is due.

Do People With Multiple Businesses Pay National Insurance Separately?

Someone operating more than one self-employed business will generally have their taxable profits considered together for Class 4 National Insurance purposes.

For example, a person may earn £15,000 in taxable profit from website development and £10,000 from a separate photography business.

The combined taxable profit would ordinarily be £25,000.

Using the standard Class 4 calculation:

£25,000 − £12,570 = £12,430

£12,430 × 6% = £745.80

The estimated Class 4 contribution would be £745.80.

The individual would not normally receive a separate £12,570 Class 4 threshold for each trade.

However, trade-specific losses and other adjustments may affect the final calculation.

The person should maintain separate records for each business and report the relevant trading activity correctly.

Do Limited Company Directors Pay Class 4 National Insurance?

Not usually on income received solely in their capacity as a limited company director.

A limited company is legally separate from its shareholders and directors.

Where a director receives a salary, employee and employer National Insurance rules may apply.

Dividends are generally not subject to National Insurance contributions, although dividend tax rules may apply.

A director who separately operates a sole-trader business may still have a Class 4 liability on the profits from that independent activity.

For example, a person could receive a director’s salary from a marketing company while earning separate taxable profits through an unincorporated consultancy.

The two sources of income require different consideration.

Business owners should not assume that incorporating automatically produces a lower overall tax burden. Corporation Tax, dividend taxation, salaries and employer National Insurance must also be considered.

What Happens to National Insurance After State Pension Age?

Self-employed individuals generally stop paying Class 4 National Insurance from the beginning of the tax year following the date they reach State Pension age.

For example, someone who reaches State Pension age in September 2026 would normally stop being liable for Class 4 from 6 April 2027.

They may still have Class 4 contributions due on 2026/27 profits.

Class 2 contributions are no longer treated as paid after reaching State Pension age.

Continuing to operate a business does not remove the obligation to report taxable income or pay any Income Tax due.

The treatment differs from employees, who normally stop paying employee Class 1 contributions when they reach State Pension age.

Does Making Tax Digital Change National Insurance for Self-Employed People?

Making Tax Digital for Income Tax changes how qualifying sole traders and landlords record and report income to HMRC.

It does not replace the existing Class 4 contribution rates.

The rollout began on 6 April 2026 for eligible individuals whose qualifying gross income exceeded £50,000 in the relevant earlier tax year.

The timetable is:

The critical distinction is that Making Tax Digital qualifying income is generally based on gross self-employment and property income before expenses.

Class 4 National Insurance, however, is based on taxable profits.

Consider a sole trader with annual turnover of £60,000 and allowable expenses of £25,000.

Their taxable business profit would be £35,000.

The Class 4 calculation would ordinarily be based on the £35,000 taxable profit.

However, their £60,000 gross turnover could bring them within Making Tax Digital if the relevant qualifying-income test and other eligibility conditions are met.

Businesses within the new system generally need compatible software, digital financial records and quarterly updates, followed by the appropriate annual tax-return process.

Our analysis identifies this turnover-versus-profit distinction as a particularly important compliance issue for growing sole traders.

How Can Self-Employed Workers Reduce National Insurance Legally?

There are legitimate ways to avoid overpaying National Insurance, although they must reflect genuine business activity and comply with HMRC rules.

Claim eligible business expenses. Accurate expense records can reduce taxable trading profits. Only qualifying expenditure should be deducted.

Compare actual expenses with the trading allowance. For qualifying traders, the most appropriate deduction method can affect taxable profit and Class 4 liability.

Check the treatment of business losses. Eligible losses may reduce relevant profits, although Class 4 loss relief rules require careful attention.

Review Class 1 and Class 4 interactions. Individuals with both employment and self-employment income may qualify for adjustments under the annual maximum provisions.

Avoid unnecessary voluntary contributions. Before paying Class 2, check whether a qualifying year already exists and whether an additional payment will provide a benefit.

Maintain accurate records. Correctly distinguishing private spending, business costs, turnover and profit reduces the risk of incorrect calculations.

It is important to understand that some Income Tax reliefs do not reduce Class 4 National Insurance profits.

For example, personal pension contributions do not ordinarily reduce the trading-profit figure used to calculate Class 4.

Business owners should therefore distinguish legitimate expense deductions from personal tax-planning arrangements.

What Are the Most Common National Insurance Mistakes Made by Self-Employed People?

Even experienced business owners can make errors when interpreting contribution thresholds.

From a financial-management perspective, the most effective approach is to review National Insurance alongside Income Tax, rather than as an isolated annual charge.

Keeping reliable records throughout the year makes it easier to forecast profit, identify liabilities and avoid last-minute payment problems.

How Much Money Should Self-Employed People Set Aside for Tax and National Insurance?

There is no single savings percentage suitable for every self-employed person.

A trader whose profit falls within the basic-rate Income Tax band may face a 20% Income Tax rate on the relevant slice of taxable income and a 6% Class 4 rate on the relevant slice of self-employed profits.

A higher-rate taxpayer may face a 40% marginal Income Tax rate alongside a 2% Class 4 marginal rate on profits above £50,270.

These are marginal rates rather than percentages payable on every pound earned.

Other factors can include:

• Employment income already using the Personal Allowance.
• Scottish Income Tax rates.
• Student loan repayments.
• Payments on account.
• Pension contributions and tax relief.
• Other taxable income.

Our recommended financial-planning approach is to calculate estimated liabilities using projected taxable profit and update the calculation regularly.

A separate business tax savings account can help prevent HMRC payments from disrupting operational cash flow.

Business owners can also use HMRC’s tax-estimation tools, although estimates should be reviewed against their individual circumstances.

Final Assessment: What Should Self-Employed People Know About National Insurance in 2026/27?

The 2026/27 National Insurance system remains comparatively straightforward for sole traders with a single source of self-employment income.

The central figures are £7,105 for the Small Profits Threshold, £12,570 for the Class 4 Lower Profits Limit, 6% for the main Class 4 rate and 2% for profits above £50,270.

Our calculations demonstrate that a person making £30,000 in taxable annual profit would normally pay £1,045.80 in Class 4 contributions, while someone making £60,000 would pay approximately £2,456.60.

However, National Insurance management involves more than calculating a percentage.

Understanding voluntary Class 2 contributions, pension eligibility, payments on account and Making Tax Digital requirements can make a substantial difference to long-term financial planning.

For freelancers and growing businesses, reviewing their contribution position annually and maintaining accurate financial records remains an essential part of managing tax obligations responsibly.

Frequently Asked Questions

Can Self-Employed People Receive a National Insurance Qualifying Year Without Paying?

Yes. In 2026/27, Class 2 contributions are generally treated as paid where qualifying self-employed profits reach £7,105, protecting the National Insurance record without an actual Class 2 charge.

How Much Voluntary Class 2 National Insurance Costs for a Full Year?

The 2026/27 weekly rate is £3.65. A full 52-week period would cost £189.80, although the amount payable depends on eligibility and the period being covered.

Can a Self-Employed Person Pay National Insurance Monthly?

Class 4 National Insurance is normally settled through Self Assessment rather than mandatory monthly deductions. Individuals can nevertheless save money regularly or use available HMRC payment arrangements.

Does National Insurance Apply to Freelance Work Completed Alongside a Full-Time Job?

It can. Class 4 normally applies where taxable self-employment profits exceed £12,570, subject to any applicable adjustments. Employment contributions do not automatically remove the liability.

Are Class 4 National Insurance Contributions Tax-Deductible?

No. Class 4 contributions are not normally deducted as an ordinary business expense when calculating taxable trading profit.

Does Paying More Class 4 National Insurance Increase the State Pension?

No. Class 4 does not directly generate State Pension entitlement. Qualifying Class 2 contributions and the person’s wider National Insurance record determine the relevant entitlement.

Can National Insurance Contributions Be Refunded If Someone Overpays?

Yes, overpayments may be refundable where the applicable rules permit. The individual should review their National Insurance record and Self Assessment calculations and contact HMRC where necessary.
