    What is self-employment?

    You will be treated as self-employed for tax purposes if you run your own business and are responsible for operations, income, and expenses. Unlike employees, self-employed individuals are not tied to a single employer and have greater autonomy over how, when, and where they work.

    Examples of self-employed individuals include freelancers, sole traders and contractors.

    Can I be employed and self-employed at the same time?

    For employment law purposes, you can be both employed and self-employed simultaneously. You can also choose to be solely employed, working for a company, or exclusively self-employed, working for yourself.

    Here’s a breakdown of the key differences between being employed and self-employed:

    Key Differences Between Being Employed and Self-Employed
    Difference Employed Self-Employed
    Contract Employment contract Contract for service
    Payment Frequency Paid monthly or weekly based on terms of engagement. Paid upon completion of tasks or milestones, as per contract terms.
    Supervision Supervised by an employer. You supervise yourself.
    Control over outcomes Less control: work is directed by the employer with set tasks and responsibilities. Greater control over how work is done and pricing; can choose clients and projects.
    Responsibility for financial risk Minimal financial risk; employer covers operational costs and provides tools. Bears significant financial risk, including costs for tools, marketing, compensation in case of defective workmanship and overheads.
    Income stability Salary or wages are predictable according to the contracted payment cycle. Income is unpredictable and dependent on the availability of contracts.
    Tax responsibility Taxes are calculated by the employer and paid at source through Pay As You Earn (PAYE Reference number). The individual is responsible for calculating and paying taxes through self-assessment.
    Liability for losses Employees receive fixed salaries regardless of company performance. Bears liability for losses and profits/income fluctuates depending on the performance of the business.
    Place of work Determined by the employer. You can only work from home, subject to the employer’s approval. You decide where, when, and for whom you work.
    Delegation and Exclusivity You work exclusively for your employer unless your contract permits other work. You may have restrictions like non-compete clauses. You can work for multiple clients and delegate tasks to others who share your skills.
    Scope of work Varies depending on the needs of the employer. Defined by the terms of the contract, with any changes requiring review.
    Benefits Entitled to benefits like NICs, holiday pay, and sick leave. Not entitled to benefits like holiday pay or sick leave.

    Being both employed and self-employed allows you the flexibility to explore different income streams and expand your skill set. Still, it’s essential to understand the responsibilities and legal obligations of each status.

    Can I be working for someone but on a self-employed basis?

    Yes, you can work for someone on a self-employed basis through a contract for service. This means you are providing services as an independent contractor rather than being employed by them. Operate in a service-based profession, such as accounting or consulting. You can offer your skills either as a sole trader, through a limited company, or as part of a Limited Liability Partnership (LLP).

    Working this way gives you more control over how you manage your business, including when, where, and for whom you work. However, you are responsible for your taxes, insurance, and compliance with legal obligations.

    In what circumstances can an individual’s status be false self-employment?

    False self-employment occurs when an individual is classified as self-employed, but their working conditions align more closely with those of an employee. Some employers often use this misclassification to bypass their obligations, such as paying employees tax and National Insurance contributions (NICs).

    Signs that an individual is falsely classified as self-employed include:

    • The individual works exclusively for one company.
    • The company dictates work schedules, tasks, and how the work should be performed.
    • The individual has limited autonomy over their work or business decisions.

    If HMRC investigates and finds that the individual should be classified as an employee, the employer may be required to reclassify the worker correctly. This could result in the employer being held accountable for unpaid taxes and contributions. Sometimes, the employee may also need to address any discrepancies resulting from the misclassification.

    Warning

    If an individual is reclassified from self-employed to employee status, the employer may face substantial tax and NIC liabilities, potentially for past years. HMRC may allow offsetting of tax already paid by the individual against the employer’s new PAYE liabilities, but only in specific circumstances.

    Since 6 April 2008, HMRC can issue a “direction”; allowing this offset, provided certain conditions are met, such as proper self-assessment by the individual. However, interest and penalties may still apply to the employer for any unpaid amounts. NIC contributions may also need adjustment, with HMRC often reallocating incorrectly paid Class 2 contributions as Class 1.

    What employment rights do I have if I am employed or self-employed?

    The main difference between being employed and self-employed lies in rights and responsibilities. Employees have statutory rights such as paid holidays, sick pay, maternity leave, and protection from unfair dismissal. Their employer handles tax deductions and provides a guaranteed income.

    On the other hand, self-employed individuals run their businesses, controlling their work schedule and earnings but with no entitlement to paid leave or employer-provided benefits. They are responsible for managing taxes and have fewer legal protections, relying on contracts and health and safety laws for specific rights.

    How does IR35 apply when working for one company?

    Also known as off-payroll working, IR35 is an anti-tax avoidance measure introduced by HMRC to prevent companies from misclassifying individuals as contractors when they effectively function as employees. It primarily targets freelance contractors working through intermediaries, such as limited or personal service companies, especially those working for one client, who would otherwise be deemed employees if the intermediary didn’t exist.

    If a contractor operates through an intermediary but meets the criteria of an employee, IR35 applies, and the contractor is taxed as if they are employed. However, IR35 rules exclude businesses classified as “small,” meaning these businesses are not required to assess or declare the employment status of contractors.

    If I work for an employer and am a self-employed contractor, what is the most tax-efficient way to pay myself?

    If you are employed and work as a self-employed contractor, the best way to manage your earnings efficiently for tax purposes depends on how you set up your self-employment. Each business structure has different tax implications, including how income is taxed and reported.

    If you operate as a sole trader, your self-employment income is taxed under Income Tax through Self Assessment. In addition, any salary you earn through your employer under PAYE must be declared as you complete a self assessment tax return. This ensures that HMRC has a complete picture of your total income, which helps calculate the correct tax and national insurance contributions.

    For those who establish a Limited Liability Partnership (LLP), the tax treatment is similar to that of a sole trader. An LLP is treated as a “pass-through” entity, meaning the profits are taxed as personal income rather than at the partnership level. This makes the LLP tax-efficient for individuals who work collaboratively with others or use a dormant company as a partner.

    Setting up a limited company offers additional options for tax efficiency. You can draw income as a salary, taxed under PAYE, or as dividends, subject to the dividend tax rate. Dividends often provide a more tax-efficient way to withdraw profits from your company, especially if your total income falls below higher tax thresholds. However, if you are an office holder without taking any salary or dividends, you may only need to pay tax if you receive other benefits or payments.

    How do I pay taxes to HMRC if I am both employed and self employed?

    If you are both employed and self-employed, your taxes are handled as follows:

    1. Employment income: Your employer deducts Income Tax and NI through PAYE.
    2. Self-employed income: You report your earnings through a Self Assessment tax return and pay any additional Income Tax and NI owed.

    Declare your PAYE salary and self-employment income in your Self Assessment to give HMRC a full view of your taxable earnings.
