Employment status in the UK: employee, worker or self-employed
Employment law in the UK recognises three main working statuses, employee, worker and self-employed, yet tax law recognises only two, employee and self-employed [1][5]. That mismatch is the single biggest source of confusion in the field: a person can be a worker for employment rights and self-employed for tax at the same time [5].
Getting status right decides two separate things: which employment rights a person can claim, and how their income is taxed. An employer that misreads either can face back-pay claims, unpaid holiday, and an HMRC bill for tax and National Insurance. This explainer sets out the three statuses, the rights and tax that attach to each, and why the two frameworks do not always line up.
Key takeaways
- UK employment law recognises three main statuses: employee, worker and self-employed [1].
- Tax law recognises only two: employed and self-employed [5].
- Employees hold the fullest set of rights; workers hold a core set from day one; the self-employed hold almost none [4].
- Employees are taxed through PAYE and Class 1 National Insurance; the self-employed pay through Self Assessment and Class 2 and Class 4 [6].
- Status turns on the real working relationship, not the label in a contract [3].
The three main statuses
An employee works under a contract of employment and holds the fullest set of rights, some of which build up with length of service, alongside responsibilities such as turning up to work as agreed [2]. A worker, sometimes called a limb (b) worker, has a contract to perform work personally but with more freedom over how much, when and where they work; workers hold a core set of rights from day one, with no qualifying period [4]. A self-employed person runs a business on their own account and, in most cases, falls outside employment law entirely, because they are their own boss [3].
Every employee is also a worker, but a worker who is not an employee holds fewer rights [4]. Two further categories, director and office holder, sit alongside the three main statuses for specific purposes, but most workforce questions come down to the employee, worker and self-employed distinction [1].
What rights attach to each status
The table below summarises how the main rights differ across the three statuses.
| Right | Employee | Worker | Self-employed |
|---|---|---|---|
| National Minimum or Living Wage | Yes | Yes | No |
| Paid holiday | Yes | Yes | No |
| Protection from discrimination | Yes | Yes | Limited |
| Statutory sick and family pay | Yes | Varies | No |
| Unfair dismissal and redundancy | Yes | No | No |
Workers gain the pay-related and anti-discrimination protections from their first day, because limb (b) rights do not depend on continuous service [4]. Employees add the service-related protections on top, including unfair dismissal and statutory redundancy once they meet the relevant conditions [2]. The self-employed rely on their contract and general law rather than employment rights [3].
How each status is taxed
Tax law ignores the worker category and asks a simpler question: employed or self-employed [5]. An employer must operate PAYE and Class 1 National Insurance on an employee's wages and pay it to HMRC, whereas a self-employed person reports income through Self Assessment and pays their own National Insurance [6].
The National Insurance treatment differs by class, as the table shows for the 2026-27 tax year.
| Status | NI class | Main rate | Collected via |
|---|---|---|---|
| Employee | Class 1 | 8% above £242/week | PAYE |
| Employer (on employee pay) | Class 1 secondary | 15% above £96/week | PAYE |
| Self-employed | Class 4 | 6% on profits £12,570 to £50,270 | Self Assessment |
Employees pay Class 1 at 8% between the Primary Threshold and the Upper Earnings Limit, then 2% above it, and the employer adds secondary Class 1 at 15% [6]. The self-employed pay Class 4 at 6% on profits within the main band and Class 2 credits protect their record once profits pass the small-profits threshold [6]. An employer running its people through UK payroll software applies the right Class 1 category automatically, while accountants handling mixed workforces across clients manage the split through a multi-client payroll dashboard.
Why tax status and rights can diverge
Because the two frameworks use different tests, a single person can land in different categories under each. It is possible to be a limb (b) worker for employment rights, and so entitled to the minimum wage and paid holiday, while being self-employed for tax [5]. This is common in casual and platform work, where the working relationship carries some employment features but the person still files their own tax return.
The label in a contract does not settle the question. Courts and HMRC look at the reality of the working relationship, focusing on control, personal service and whether the individual genuinely runs their own business [3]. Where a business engages contractors through their own limited companies, a related set of rules, the off-payroll working rules, governs the tax side; the Moonworkers overview of the off-payroll working rules explains how that interacts with status.
Getting it wrong
Misclassifying a worker as self-employed exposes an engager to two separate risks. On the rights side, a misclassified individual can bring tribunal claims for unpaid holiday, unlawful wage deductions and, for employees, unfair dismissal [4]. On the tax side, HMRC can pursue unpaid Income Tax and National Insurance where PAYE should have applied [6].
The safe approach is to assess each engagement on its facts, keep a record of the reasoning, and revisit it if the working pattern changes. A genuine self-employed contractor who occasionally needs a compliant payslip for their own company can produce one with an instant payslip generator, while a platform that pays a mix of workers and contractors can run the calculations through an HMRC-recognised payroll API that applies the correct tax treatment to each.
Conclusion
Employment status is really two questions wearing one name. Employment law sorts people into employees, workers and the self-employed to decide their rights, while tax law collapses that into employed or self-employed to decide how income is taxed. The two answers usually agree, but not always, and the gap is where costly mistakes happen.
The direction of travel is towards more scrutiny, not less, as casual and platform work keeps testing the boundaries of the worker category in the courts. An engager that treats status as a documented, reviewable judgement, rather than a label chosen at the start, is best placed to stay compliant on both the rights and the tax side as the definitions continue to be refined.
Frequently asked questions
What is the difference between a worker and an employee?
An employee works under a contract of employment and holds the fullest set of rights, some of which build up with length of service, such as unfair dismissal protection and statutory redundancy pay [2]. A worker has a contract to perform work personally but with more freedom over hours and commitment, and holds a core set of rights, including the minimum wage and paid holiday, from day one [4]. Every employee is also a worker, but not every worker is an employee.
Can someone be self-employed for tax but a worker for rights?
Yes. Tax law recognises only employed and self-employed, whereas employment law adds the worker category, so the two frameworks can classify the same person differently [5]. A limb (b) worker can be entitled to the minimum wage and holiday pay while still filing a Self Assessment return and paying self-employed National Insurance [6]. This is common in casual and platform work.
How is employment status decided?
Status turns on the real working relationship rather than the label in a contract [3]. Courts and HMRC weigh factors such as control, whether the work must be done personally, and whether the individual genuinely runs a business of their own [3]. A contract describing someone as self-employed carries little weight if the day-to-day reality looks like employment.
How does National Insurance differ between employed and self-employed?
An employee pays Class 1 National Insurance at 8% on earnings between the Primary Threshold and the Upper Earnings Limit through PAYE, and the employer adds secondary Class 1 at 15% [6]. A self-employed person pays Class 4 at 6% on profits within the main band through Self Assessment, with Class 2 credits protecting their record above the small-profits threshold [6]. The employer duty to operate PAYE only arises for employed status.
