MTD First Quarter Checklist for Sole Traders: 12 Essential Steps to Avoid Costly Mistakes
July 27, 2026Can you employ your spouse or children in your business and pay them a salary? For many UK business owners, the answer can be yes. Employing a husband, wife, civil partner or child can be perfectly legitimate, and the salary paid may potentially reduce the taxable profits of the business. However, simply putting a family member on the payroll does not automatically make their wages an allowable business expense.
HMRC will generally expect the employment to be genuine, the work to be necessary for the business and the level of pay to be commercially reasonable for the duties performed. This is particularly important when employing family members because arrangements between connected people can attract additional scrutiny.
Understanding the rules before putting a relative on the payroll can help you structure the arrangement correctly, maintain appropriate records and avoid unexpected tax problems.
Can You Employ Your Spouse or Children Legally?
Can you employ your spouse or children in a UK business? In principle, yes. There is no general rule preventing a sole trader, partnership or limited company from employing a family member.
Your spouse could, for example, undertake bookkeeping, administration, customer service, marketing, appointment management or other genuine duties. An older child might help with filing, social media, stock management, administration or other suitable work.
The important point is that the employment relationship must be genuine. Paying a family member simply because they are related to you is not enough.
HMRC may consider whether the person actually performs the stated work, whether the business needs that work and whether the salary represents a reasonable commercial reward.
The arrangement should therefore look much like one you would be comfortable offering to an unrelated employee performing similar duties.
Why Business Owners Employ Family Members
There can be genuine commercial reasons for employing family members. A spouse may already understand how the business operates and could provide reliable administrative support. A child may work part-time during school, college or university holidays.
There can also be tax advantages where the arrangement is structured correctly. A genuine salary will normally be considered when calculating the taxable profits of the business, subject to the normal rules for deductibility.
For a limited company, an allowable salary generally reduces the company’s taxable profit and therefore potentially reduces its Corporation Tax liability.
However, tax savings should be the consequence of genuine employment rather than the sole reason for creating it.
The Salary Must Be Commercially Justifiable
One of the most important considerations when asking can you employ your spouse or children is how much they should be paid.
The salary should reflect the actual duties performed, hours worked, responsibilities involved, experience required and the rate that would reasonably be paid to another person doing similar work.
Suppose your spouse performs five hours of basic administration each week. Paying a commercially reasonable hourly rate may be straightforward to justify. Paying a substantial annual salary for those limited duties could be much harder to defend.
Similarly, paying a child thousands of pounds for occasional help with filing or social media could create questions about whether the expense was incurred wholly and exclusively for business purposes.
Keep evidence supporting both the work and the amount paid.
What Work Can Your Spouse Do?
The appropriate duties depend on your particular business. A spouse might legitimately assist with bookkeeping, invoicing, diary management, answering customer enquiries, maintaining business records, marketing, social media or general administration.
In a larger business, they might have more substantial responsibilities, such as managing staff, handling suppliers or overseeing a department.
What matters is that the role exists because the business genuinely requires it.
A written job description can be useful. It establishes what the employee is responsible for and helps demonstrate the commercial basis of the employment.
Can You Employ Your Spouse or Children Through a Limited Company?
Can you employ your spouse or children through your limited company? Yes, provided the employment is genuine and the normal employment and tax rules are followed.
The company is legally separate from its shareholders and directors. Therefore, the family member should normally be treated as an employee of the company where that is the nature of the arrangement.
This can involve operating PAYE where required, producing payslips, making salary payments and complying with workplace pension and employment law obligations where applicable.
The company should also maintain records demonstrating what the family member actually does.
Avoid simply processing a salary through payroll while leaving the money in the company’s bank account. Actual salary payments to the employee provide much stronger evidence that a genuine employment arrangement exists.
What About Sole Traders?
A sole trader can also employ a spouse or child.
The same basic principle applies: wages should relate to genuine work performed for the business and should be reasonable for that work.
An important distinction is that a sole trader cannot employ themselves. However, they can employ another individual, including a spouse or eligible child.
Provided the expense satisfies the relevant tax rules, employment costs may be deductible when calculating taxable business profits.
Employing Your Children
Employing children requires additional care because UK rules restrict when and how children can work.
Rules can vary depending on the child’s age and local authority requirements. There are restrictions covering working hours, types of work and employment during school periods.
Children under the minimum school leaving age have stronger protections, and certain types of work are prohibited.
Once someone reaches the relevant age, the normal National Minimum Wage rules may also become applicable depending on their circumstances.
Therefore, can you employ your spouse or children should not be treated purely as a tax question. Employment law must also be considered.
PAYE and National Insurance
Employing a family member does not automatically exempt the business from PAYE requirements.
Whether Income Tax or National Insurance contributions arise depends on factors including salary levels and the employee’s circumstances.
Where required, the employer must operate payroll correctly and report payments to HMRC through Real Time Information.
This means keeping accurate payroll records and making submissions at the appropriate time.
Thresholds and rates can change between tax years, so businesses should use the figures applying to the relevant period rather than relying on historic salary recommendations.
National Minimum Wage Rules
Another important consideration is the National Minimum Wage.
Depending on the type of business, relationship and employment arrangement, specific exemptions or rules can apply. For example, certain family members working in a family business may be treated differently under minimum wage legislation.
However, you should not assume that every family member is automatically outside National Minimum Wage requirements.
The precise employment circumstances should be reviewed before deciding what salary or hourly rate to use.
Even where a particular exemption applies, the amount paid still needs to make sense from a tax deductibility perspective.
Keep Proper Employment Records
Documentation can make a significant difference if HMRC later asks questions about payments to family members.
Consider maintaining an employment contract, job description, timesheets or records of hours, payroll records, payslips and evidence of salary payments.
For example, if your spouse manages invoices for three hours each week, maintaining a basic record of those hours creates evidence that the employment is genuine.
Payments should ideally be made directly from the business bank account to the employee’s own bank account.
This creates a clear audit trail connecting the payroll records with the actual salary paid.
Avoid Artificial Salary Arrangements
A common mistake is deciding how much unused Personal Allowance a spouse or child has and then creating a salary purely around that figure.
Tax allowances can certainly form part of sensible remuneration planning, but they should not determine the commercial value of the work.
For example, suppose a family member’s duties would reasonably cost the business £4,000 per year if performed by someone else. Paying them significantly more simply because they have unused tax allowances could be difficult to justify.
Start by determining the role, duties, hours and commercial rate. Tax planning should follow from that assessment.
What If Your Company Is Not Trading?
This is an important area that can easily be overlooked.
Where a company is dormant, inactive or not genuinely trading, it may be much harder to establish a commercial reason for employing someone.
If there is little or no business activity, HMRC could reasonably ask why an employee was required and what work they were actually performing.
A company should not create a salary simply to utilise a spouse’s or child’s tax allowances.
Where a business has not started trading, the treatment of costs may also differ depending on the nature and timing of the expenditure.
Therefore, can you employ your spouse or children needs to be considered in the context of what the business is actually doing.
Workplace Pension Responsibilities
Family members who become employees may also fall within workplace pension legislation.
Depending on age and earnings, the employer may have automatic enrolment responsibilities. Even where automatic enrolment does not apply, an employee may have rights relating to joining a workplace pension scheme.
Employing relatives does not necessarily remove these obligations.
Business owners should therefore consider payroll, employment law and pension responsibilities together.
Corporation Tax and Income Tax Considerations
For limited companies, genuine employment costs that satisfy the normal tax rules can generally reduce taxable profits.
For example, a commercially justified salary and associated employer costs could potentially reduce the company’s Corporation Tax liability.
The employee, meanwhile, is taxed according to their own circumstances.
This can sometimes make employing a spouse tax-efficient, particularly where they genuinely contribute to the business and have lower income from other sources.
However, can you employ your spouse or children should never be approached solely as a method of transferring taxable profits between family members.
The underlying commercial arrangement remains essential.
Common Mistakes to Avoid
Some arrangements are much more likely to create difficulties than others. These include paying a salary when no work is performed, paying substantially more than the role is worth, creating employment only for tax purposes, failing to actually transfer the salary and keeping no evidence of the work performed.
Another mistake is assuming that because the person is a family member, employment rules do not apply.
Depending on the circumstances, PAYE reporting, pension duties, employment rights and minimum wage legislation may still need consideration.
Keeping the arrangement commercial from the outset can prevent many of these problems.
Can You Employ Your Spouse or Children and Save Tax?
Potentially, yes.
A genuine family employment arrangement can be commercially useful while also providing tax advantages. The business obtains help it genuinely needs, the family member receives remuneration for their work and allowable employment costs may reduce taxable profits.
But the order matters.
First establish what work the business requires. Then determine who will perform it, how many hours are needed and what a reasonable commercial rate would be. After that, consider the tax consequences.
This approach is much stronger than choosing a salary based on the desired tax saving and trying to justify the employment afterwards.
Final Thoughts

Can you employ your spouse or children in your business? Yes, and for many UK businesses it can be a legitimate and practical arrangement. However, can you employ your spouse or children tax-efficiently depends on much more than simply adding their name to the payroll.
When considering can you employ your spouse or children, make sure there is genuine work, a genuine business need and commercially reasonable pay. The question can you employ your spouse or children should also involve checking PAYE, National Insurance, employment law, National Minimum Wage and workplace pension obligations where relevant.
Ultimately, can you employ your spouse or children successfully comes down to commercial reality and good record keeping. If the role is genuine, the work is actually performed and the remuneration can be justified, employing family members can form part of sensible business planning. Before implementing an arrangement, obtain advice based on your specific business structure and the family member’s circumstances.
