Employment vs Self-Employment Status for ACCA ATX-UK

Updated 11 October 2026 · Fact-checked

Employment status decides whether a worker is taxed as an employee (PAYE, Class 1 NIC, employment income) or as self-employed (trading profits, self assessment, Class 4 NIC). There is no single statutory test. You weigh the facts using the badges of status: control, personal service, substitution, mutuality of obligation, equipment, financial risk and integration.

Understand Employment vs Self-Employment Status

Status matters because the tax result is very different. An employee is taxed on earnings through PAYE, and both employee and employer pay Class 1 NIC. A self-employed person is taxed on trading profits after expenses, pays Class 4 NIC on profits, and the client pays no NIC on the fees.

There is no single legal definition. Courts and HMRC look at the whole picture of the working relationship. The label in the contract does not decide it. If the real working practice differs from the paperwork, the practice wins.

You weigh factors for and against. Employment points include: the client controls how, when and where the work is done; the worker must do the work personally; the client must offer work and the worker must accept it (mutuality of obligation); the worker uses the client's equipment; the worker is paid regularly and takes no financial risk; the worker is part of the organisation and receives benefits such as holiday pay.

Self-employment points include: the worker can send a substitute; the worker chooses how and when to work; the worker supplies significant equipment; the worker bears financial risk, such as fixed-price contracts and bearing the cost of correcting poor work; the worker has several clients and is paid on invoice.

A related issue is the intermediary rules (often called IR35) where a worker supplies services through their own company. These look through the company and ask whether the worker would have been an employee had they contracted directly. The same status factors are used.

The consequences matter in the exam. If a worker is treated as self-employed but is actually an employee, the client faces PAYE and NIC liabilities, interest and penalties. Your advice must cover both sides: the client's risk and the worker's position.

Key rules to remember

Class 1 employee NIC
Nil on £1 – £12,570; 8% on £12,571 – £50,270; 2% above £50,270 (annual)
Paid by the employee through PAYE. Rates are from the tax tables given in the exam.
Class 1 employer NIC
Nil on £1 – £5,000; 15% above £5,000 (annual)
Paid by the employer on earnings. Employment allowance of £10,500 may reduce the bill if the employer is eligible.
Class 4 NIC (self-employed)
Nil on £1 – £12,570; 6% on £12,571 – £50,270; 2% above £50,270
Charged on trading profits, not on fees received. No employer NIC arises on payments to a self-employed person.
Class 1A NIC
15% of taxable benefits in kind
Employer only. Arises only if the worker is an employee.
Status test approach
Control + personal service + mutuality of obligation + substitution + equipment + financial risk + integration
No single factor is decisive. Weigh the whole relationship and conclude.

How to solve Employment vs Self-Employment Status questions

Use this method for any question asking you to decide status or explain the consequences.

  1. 1Read the requirement. Decide whether you must conclude on status, compare the tax cost, or advise on risk.
  2. 2Pick out the facts in the scenario and sort them into 'points to employment' and 'points to self-employment'.
  3. 3Name each factor you use (for example control, substitution, financial risk) and link it to a specific fact.
  4. 4Weigh the factors. Do not count them mechanically; say which matter most and reach a clear conclusion.
  5. 5State the consequences: for an employee, PAYE, Class 1 employee and employer NIC, and possible Class 1A. For self-employed, trading profit, expenses and Class 4 NIC.
  6. 6Calculate the NIC or tax if asked. Show workings to the nearest £ and use the tax table rates.
  7. 7Add advice for the client and the worker, including the risk of HMRC challenge, interest and penalties, and any practical steps.

Quickest way: Two-column badge sort

When to use it: Use it when a scenario gives many facts about a working arrangement and you have limited time.

  1. Draw two columns on your answer plan: Employee and Self-employed.
  2. Scan the scenario once and write each fact in the correct column with a one-word badge label.
  3. Circle the two or three strongest facts, usually control, substitution and financial risk.
  4. Write your conclusion first, then the supporting points, then the NIC and tax effect.
  5. Finish with one sentence on the HMRC risk if the status is doubtful.

Common mistakes in Employment vs Self-Employment Status

  • Relying on the contract label alone

    The scenario says 'self-employed consultant' and students accept it.

    Fix: Say that the label is not decisive and test the actual working practice against the badges.

  • Listing badges without applying them to facts

    Students memorise a list and write it out.

    Fix: Tie each badge to a fact in the scenario and say which way it points. Marks go for application.

  • Giving no conclusion

    Students fear being wrong when the facts are mixed.

    Fix: Weigh the factors and commit to a view, noting the uncertainty. A reasoned conclusion earns marks.

  • Ignoring NIC consequences

    Focus stays on income tax.

    Fix: Always state Class 1 employee and employer, Class 1A where benefits arise, or Class 4 for the self-employed.

  • Applying Class 4 to gross fees or applying employer NIC to a self-employed person

    Confusion between the two regimes.

    Fix: Class 4 applies to profits after expenses. There is no employer NIC on payments to a genuinely self-employed person.

  • Forgetting professional skills and the risk side

    Students treat it as a pure technical question.

    Fix: Show scepticism about the facts, give commercial advice, and explain the risk of interest and penalties for the client.

Worked examples

Example 1

Priya provides IT support to a company. She works set hours at the company's office, uses its computers, must do the work herself, is paid a fixed monthly sum, and takes no risk if work is faulty. She has no other clients. The contract calls her self-employed. Advise on her status and compute the annual NIC cost to the company if her annual pay is £40,000 and the company cannot claim employment allowance.

Show the solution
  1. Control: the company sets her hours and place of work. This points to employment.
  2. Personal service: she must do the work herself, with no right of substitution. Employment.
  3. Equipment and risk: she uses the company's computers, is paid a fixed sum and bears no financial risk. Employment.
  4. Integration and other clients: she has no other clients, so she depends on one business. Employment.
  5. Conclusion: despite the contract label, she is almost certainly an employee. The company should operate PAYE and Class 1 NIC.
  6. Employer Class 1 NIC: (£40,000 − £5,000) × 15% = £35,000 × 15% = £5,250.
  7. Employee Class 1 NIC for Priya: (£40,000 − £12,570) × 8% = £27,430 × 8% = £2,194 (to the nearest £, £2,194.40).
  8. Risk: if the company wrongly treats her as self-employed, HMRC can assess the PAYE and NIC due, with interest and possible penalties.

Answer: Priya is an employee. The company's employer Class 1 NIC is £5,250 a year. Priya's employee Class 1 NIC is £2,194 a year.

Example 2

Tom is a self-employed carpenter with trading profits of £60,000 for 2025/26. Compute his Class 4 NIC and explain why no employer NIC arises on his client's payments.

Show the solution
  1. Tom is genuinely self-employed, so Class 4 NIC is charged on his trading profits.
  2. Band £1 – £12,570 is nil.
  3. Main band: (£50,270 − £12,570) × 6% = £37,700 × 6% = £2,262.
  4. Upper band: (£60,000 − £50,270) × 2% = £9,730 × 2% = £194.60, which is £195 to the nearest £.
  5. Total Class 4 NIC = £2,262 + £195 = £2,457.
  6. His clients pay him fees without PAYE. No Class 1 employer NIC arises because he is not an employee.

Answer: Tom's Class 4 NIC is £2,457. No employer NIC arises because he is not employed by his clients.

Exam tips

  • Always reach a clear conclusion on status. State the key factors and which ones tip the balance.
  • Quote facts from the scenario next to each badge. A bare list of tests earns little.
  • Use the NIC rates from the tax tables in the exam and show workings to the nearest £.
  • Cover both parties. Advise the client on PAYE and NIC risk and the worker on how their tax position changes.
  • Mention the intermediary (IR35) issue when a worker supplies services through their own company, and apply the same status factors.

Employment vs Self-Employment Status: frequently asked questions

Is there one test for employment status in the UK?

No. Status is decided by looking at the whole working relationship. You weigh factors such as control, personal service, mutuality of obligation, substitution, equipment and financial risk.

Does a contract saying someone is self-employed settle the matter?

No. The real working practice matters more than the label. If the facts show an employment relationship, the worker is treated as an employee.

What NIC applies to self-employed people?

They pay Class 4 NIC on trading profits, at 6% between £12,570 and £50,270 and 2% above that. The tax tables in the exam give these rates.

What is the risk to a business that wrongly treats a worker as self-employed?

HMRC can assess the unpaid PAYE and NIC, plus interest and penalties. Your answer should flag this risk and suggest reviewing the working arrangements.
