Can I Be a Sole Trader and Employed at the Same Time in the UK?

Can I Be a Sole Trader and Employed at the Same Time in the UK?

Yes, a person can be employed and operate as a sole trader at the same time in the UK. Someone could work full-time or part-time for an employer while also running a freelance business, consultancy, online store, trade or other side business.

HMRC specifically confirms that a person can be employed and self-employed simultaneously. For example, someone might work for an employer during the day and operate their own business during evenings or weekends.

The important point is that the employment and sole trader activity are treated separately for tax and administrative purposes.

How Can Someone Be Employed and a Sole Trader at the Same Time?

Being employed describes a person’s relationship with an employer, while being a sole trader describes how they operate their own business.

For employment income, the employer will usually deduct Income Tax and employee National Insurance through PAYE.

For sole trader activity, the individual is responsible for keeping business records, calculating income and allowable expenses, and reporting their self-employed income to HMRC where required. HMRC requires sole traders to maintain records of their business income and expenses for Self Assessment purposes.

Someone who wants to understand the terminology in more detail can read about whether a sole trader is self-employed.

Area Employment Sole trader business
How income is received Salary or wages Payments from customers or clients
Tax administration Usually handled through PAYE Usually handled through Self Assessment
Expenses Limited employee expense rules Allowable business expenses may be deducted
Records Mostly maintained by employer Sole trader keeps business records
Business risk Employer carries business risk Sole trader is responsible for the business

Does a Sole Trader Need to Tell HMRC?

A person does not necessarily need to register as a sole trader simply because they have earned a small amount from occasional work.

Under the current rules, a person generally needs to register for Self Assessment as a sole trader where their gross trading income exceeds £1,000 during a tax year. Gross income means the amount earned before business expenses are deducted.

For example, suppose an employee earns £32,000 a year from their job and also makes £4,500 from freelance graphic design. The employment continues to be taxed through PAYE, but the freelance income may create separate Self Assessment obligations.

Someone beginning a side business can find further information on when to register as self-employed.

It is important not to confuse the £1,000 trading allowance with £1,000 of profit. HMRC’s threshold looks at gross trading income in determining whether registration may be required.

How Is Tax Calculated if Someone Is Employed and Self-Employed?

Having two types of work does not mean there are two completely separate Income Tax systems.

Employment income and taxable sole trader profit ultimately contribute to the individual’s overall tax position.

The employment salary is normally taxed through PAYE. The sole trader calculates business profit by taking business income and deducting allowable business expenses, subject to the relevant tax rules. HMRC confirms that qualifying business expenses can reduce the profit on which tax is calculated.

An individual’s total income may therefore affect which Income Tax band applies to their additional sole trader profits.

Simple Example

Consider someone who has:

  • Employment salary of £35,000.
  • Sole trader turnover of £12,000.
  • Allowable business expenses of £4,000.

Their sole trader profit would broadly be:

£12,000 income – £4,000 expenses = £8,000 business profit

The £8,000 does not normally replace the employee’s salary for tax purposes. Instead, it forms part of the person’s overall taxable position, subject to the relevant allowances and tax rules.

The actual amount of tax owed can vary according to factors such as tax code, pension contributions, other income, student loans and available allowances.

What Expenses Can an Employed Sole Trader Claim?

Having an employed job does not prevent someone from claiming legitimate expenses relating to their separate sole trader business.

HMRC lists several categories of allowable expenses, including qualifying office costs, travel, staff costs, stock, insurance, business premises costs, advertising and certain professional fees. Only the business proportion can normally be claimed where an expense has both personal and business use.

For instance, if a mobile phone is used partly for personal calls and partly for business calls, only the qualifying business proportion should normally be treated as a business expense.

Good record keeping is therefore important. Receipts, invoices, payment records and evidence supporting expenses should be kept appropriately.

Does Someone Pay National Insurance Twice?

Someone who is both employed and self-employed can potentially have National Insurance obligations connected with both types of income.

National Insurance deducted through employment is dealt with separately from any National Insurance liability arising from self-employment.

The amount ultimately payable depends on earnings and profits, so it is important to look at the individual’s actual circumstances rather than assuming that being employed automatically removes self-employed National Insurance obligations.

Further details are available in the explanation of self-employed National Insurance.

Can Someone Work Full-Time and Still Be a Sole Trader?

Yes. There is no general HMRC rule preventing someone from having a full-time job and operating a sole trader business outside those working hours. GOV.UK even gives the example of an employee running a separate business during evenings and weekends.

However, the employment contract should still be checked.

An employer may have contractual rules relating to:

  • Working for competitors.
  • Conflicts of interest.
  • Outside business activities.
  • Confidential information.
  • Intellectual property.
  • Use of company equipment.
  • Secondary employment.

For example, an employee working for a marketing agency might need to check their contract before providing similar marketing services privately to competing clients.

Operating a side business should also not involve using an employer’s customer database, confidential information, equipment or paid working time without permission.

Does a Sole Trader Need a Business Bank Account?

Sole Trader Business Bank Account

A sole trader and the individual are not separate legal entities in the same way that a limited company and its shareholder are.

Nevertheless, keeping business and personal transactions separate is usually helpful.

A separate account can make it easier to:

  • Identify customer payments.
  • Track business expenses.
  • Prepare accounts.
  • Calculate taxable profit.
  • Maintain evidence for HMRC.
  • Understand whether the side business is actually profitable.

A person considering formalising their side business can also review the steps involved in registering as a sole trader.

Individual banks may also have terms restricting the use of personal current accounts for business activity, so the account provider’s conditions should be checked.

What Records Should an Employed Sole Trader Keep?

Employment records such as P60s and payslips should be retained alongside appropriate business records.

HMRC says self-employed people must keep records of business income and expenses used to complete their Self Assessment tax return.

Useful business records can include:

  • Sales invoices.
  • Customer payments.
  • Supplier invoices.
  • Expense receipts.
  • Mileage records where relevant.
  • Bank transaction records.
  • Records of equipment purchases.
  • Accounting software records.

Accurate records make it much easier to calculate business profit and respond if HMRC asks for supporting information.

Does Making Tax Digital Apply if Someone Is Also Employed?

Being employed does not automatically exempt a sole trader from Making Tax Digital for Income Tax.

From 6 April 2026, Making Tax Digital for Income Tax applies to sole traders and landlords whose qualifying annual income from self-employment and property is above £50,000, subject to the detailed eligibility rules and exemptions.

Qualifying income generally refers to gross self-employment and property income before expenses rather than employment salary.

Affected taxpayers need compatible software to maintain digital records and send the required information to HMRC.

Anyone operating a larger side business can read more about the current Making Tax Digital rules.

What if the Sole Trader Business Makes a Loss?

A newly established side business does not always make a profit immediately.

If allowable business expenses are greater than business income, the sole trader may record a trading loss. There are specific tax rules governing how trading losses may be used, and the appropriate treatment depends on the circumstances.

This is one area where professional advice can be useful because loss relief can interact with other income and future business profits.

Keeping accurate records remains essential even during an unprofitable year.

Can an Employer Stop Someone Becoming a Sole Trader?

An employer cannot automatically control everything an employee does outside work, but the employment contract may contain enforceable provisions covering outside work, competition or conflicts of interest.

A person should therefore check their contract before beginning a side business, particularly if the new activity operates in the same industry.

Potential problems are more likely where the side business:

  • Competes directly with the employer.
  • Targets the employer’s customers.
  • Uses confidential information.
  • Is carried out during contracted working hours.
  • Uses company equipment without authorisation.

Where the contractual position is unclear, employment-law advice may be appropriate.

Is It Worth Being Employed and a Sole Trader?

For many people, combining employment with sole trader activity can provide a relatively practical route into business ownership.

Employment can provide predictable income while the individual tests whether a business idea attracts customers. It can also reduce the pressure to generate full-time business income immediately.

However, there are disadvantages. The person may have additional bookkeeping responsibilities, Self Assessment obligations and less free time. Business profits can also increase the person’s overall tax liability.

Potential advantage Potential drawback
Regular employment income continues More administration
Business can be tested gradually Additional tax obligations
Lower financial pressure Less spare time
Opportunity to build customers Possible employment-contract restrictions
Flexible route into self-employment Business losses remain the owner’s responsibility

Do You Need an Accountant?

There is no general requirement for every employed sole trader to use an accountant.

Someone with a straightforward side business may be able to maintain their own records and complete their tax responsibilities using HMRC guidance and suitable accounting software.

Professional advice may become more valuable where there is:

  • Significant business income.
  • VAT registration.
  • Property income.
  • International income.
  • Multiple businesses.
  • Complicated expenses.
  • Employees.
  • Making Tax Digital obligations.

The cost of qualifying accountancy and professional services used for business purposes can itself fall within the rules for allowable business expenses in appropriate circumstances.

Final Thoughts

The answer to “Can I be a sole trader and employed?” is yes. UK rules allow a person to earn a salary through PAYE while running a separate business as a sole trader.

The arrangement can be particularly useful for someone testing a business idea or building additional income without immediately giving up employment. However, the individual should keep accurate business records, register with HMRC when required, understand how business profit affects their overall tax position and check their employment contract for potential restrictions.

As the business grows, areas such as National Insurance, Making Tax Digital, VAT and professional accounting support may also become increasingly important.
