Employing family members in your business is one of the more practical tax planning routes available to owner-managed businesses.
Done properly, it can shift income from a higher-rate taxpayer to someone with unused Personal Allowance, reduce the household tax bill by thousands a year, and bring genuine extra capacity into the business.
Done badly, it produces an HMRC enquiry, a disallowed deduction, and sometimes a tax bill back on the business owner under the settlements legislation. The difference between the two is mostly about whether the work is real and the pay is commercial.
This guide covers the rules for employing a spouse, civil partner or adult children in your business, the legitimate tax savings, and the potential issues to plan around.
The Idea Behind Employing Family
The basic idea is straightforward. If you pay your spouse, civil partner or adult child a genuine wage for work they actually do for the business, the wage becomes a deductible expense. They take home what was previously profit sitting in your name – and they pay tax on it through their own Personal Allowance, basic rate band and NI thresholds.
For sole traders, that’s the whole story. Income that would have been taxed at your marginal rate ends up taxed at theirs. If they’re sitting on unused allowances, less of the household income goes to HMRC and more stays with you.
For a limited company, the comparison is a bit more involved. The salary reduces corporation tax, but the alternative would usually have been dividends, which come with their own tax cost. The fair comparison is between the household’s total tax bill under each route, not the salary deduction on its own.
It only does anything where one of you has used most of your bands and the other has spare capacity. If you’re both already on full incomes, there’s nothing useful to redistribute and the structure doesn’t help.
The Wholly and Exclusively Rule
The pivotal test is whether the salary is paid “wholly and exclusively” for the purposes of the business. HMRC’s internal guidance makes the position clear: if a family member is paid for non-business activities, or paid more than the work justifies, HMRC can disallow part or all of the deduction.
Two questions decide most cases:
- Is the work real? Genuine, business-related tasks – bookkeeping, admin, marketing, social media, customer service, deliveries, anything the business would otherwise need to do or pay someone else to do.
- Is the pay commercial? Roughly what you’d pay a third party for the same work, given the same skills, hours and responsibilities.
If both answers are yes, the salary is deductible. If the work is fictional or the pay is generous compared with what an outsider would receive, HMRC can disallow the excess.
In a limited company, an over-paid spouse’s salary can also be treated as a distribution to the director-shareholder and taxed accordingly, or caught by the settlements legislation.
Practical evidence helps. A simple employment contract, a job description, a time log or shift pattern, and payslips showing PAYE deductions all support the case that the role is real.
Employing Your Spouse or Civil Partner
The most common arrangement. A spouse or civil partner can be employed as a salaried employee, a director, or both. The structure depends on what you’re trying to achieve.
As an employee:
- PAYE applies normally: Wages, employer NI above £5,000, employee NI above £12,570, income tax above £12,570.
- National Minimum Wage applies for limited company employees (more on this below).
- The salary uses their Personal Allowance and basic rate band first, sitting in the lower-tax space.
As a director:
- They can take a salary plus dividends through a shareholding, opening up further income-splitting options.
- Both directors paid above the £5,000 Secondary Threshold can mean the company qualifies for the Employment Allowance, worth up to £10,500 of employer NI relief, subject to the normal eligibility rules. A single-director company can’t claim where that director is the only employee liable for secondary Class 1 NI.
- Shares transferred between spouses are generally CGT-neutral on a no-gain/no-loss basis, and ordinary shares with full rights are usually less exposed to settlements issues than dividend-only or restricted share classes.
A typical setup for a husband-and-wife company is two directors each taking a £12,570 salary, the Employment Allowance covering employer NI, and dividends split 50/50 according to shareholding. The arrangement works because both directors are genuinely involved in the business and the share rights are real.
Adult Children Working in the Business
Adult children at university, between jobs, or working part-time for the family business are often a natural fit for legitimate employment. The same wholly-and-exclusively test applies, but the practical points shift:
- Personal Allowance is the goal: Children with no other income can take up to £12,570 a year tax-free.
- Above £12,570: Income tax at 20% and employee NI at 8% kick in. Still substantially lower than the parent’s marginal rate in most cases.
- National Minimum Wage applies at the rates for the child’s age band (see below).
- Real work is essential: Social media, web design, delivery driving, admin, customer service. The role needs to be genuine, with hours that match the pay.
A point worth knowing if you’re paying adult children in higher education: salary income can affect their student loan repayments, maintenance loan assessment, and any means-tested benefits. The same applies to spouses receiving Universal Credit or other tested benefits.
For minor children, the picture is different. The settlements legislation can attribute income to the parent where income from a parental settlement exceeds £100 a year, although genuine wages for real work are normally analysed as employment income and a business deduction rather than as settlement income, provided the pay is commercial and PAYE, NMW and child-employment rules are followed.
For children under 16, employment is heavily restricted. Local authorities regulate child employment permits, with limits on hours, the type of work allowed, and the times children can work. Under-13s generally can’t be employed at all.
The National Minimum Wage Question
This is where a lot of family employment goes wrong, and the rules are more nuanced than people realise.
The default position is that the National Minimum Wage applies to anyone employed in the business. From 1 April 2026 the rates are:
- £12.71 per hour for workers aged 21 and over (National Living Wage)
- £10.85 per hour for workers aged 18 to 20
- £8.00 per hour for workers aged 16 to 17 and apprentices in the first year of their apprenticeship
There’s a family worker exemption that catches a lot of people out. A family member who lives in the family home, participates in running the family business, and shares in family tasks may fall outside the NMW. This exemption applies to sole traders and partnerships – but not to limited companies.
The reason is that a limited company is a separate legal entity. It can’t have a “family”. So an employee of a limited company is an employee of the company, even if they happen to be the director’s spouse and live at the same address. NMW applies in full.
One nuance worth noting: a director acting solely as an officeholder, without a separate employment or worker contract, isn’t generally treated as a worker for NMW purposes.
So a husband-and-wife company with both spouses as directors and no separate employment contract can pay each director below the NMW. Adding an employment contract changes that – NMW then applies.
PAYE, NI and Pensions
Whatever the family relationship, the payroll mechanics are the same as for any other employee:
- Register as an employer with HMRC if you haven’t already.
- Operate PAYE on the salary, with Real Time Information submissions on or before each payday.
- Pay employer NI at 15% above the £5,000 Secondary Threshold, or use the Employment Allowance if eligible.
- Auto-enrol for pensions where the family member qualifies – earnings above £10,000 a year and aged 22 to State Pension age usually trigger automatic enrolment.
The pension piece is often missed. Family members aren’t exempt from auto-enrolment just because of the relationship, and the rules require the employer to assess every worker individually. The single-director-no-other-employees exception that lets some companies avoid auto-enrolment doesn’t apply once a spouse or adult child is on payroll.
Pension contributions paid by the business for a family employee are normally deductible for corporation tax in the year they’re paid, providing they meet the wholly and exclusively test. For higher-earning family directors, this is one of the cleaner planning routes – the contributions reduce the company’s tax bill, build the family employee’s retirement pot, and sit outside both income tax and NI.
Settlements Legislation: The Trap to Plan Around
The biggest risk in family employment is the settlements legislation. HMRC can use it where an arrangement appears to be more about diverting income from one family member to another than about a genuine commercial transaction.
The clearest examples of where it bites:
- Over-paid spouses doing minimal work, where the excess is treated as the higher-earning spouse’s income
- Minor children receiving more than £100 a year from arrangements that aren’t genuine employment
- Shareholding structures where one spouse owns shares with no real rights, used purely to redirect dividends
The defence is the same in every case: real work, commercial pay, proper paperwork, and shareholdings that carry genuine rights. The Arctic Systems case confirmed that genuine spouse shareholdings with full rights are generally safe, but the bar is that the rights have to be real, not nominal.
Our tax planning service covers the structuring side of this in detail – particularly for owner-managed companies considering bringing a spouse on as a director or shareholder.
Five Common Scenarios
Here’s how this plays out at typical owner-manager profit levels. The figures below are simplified illustrations using 2026/27 rates – they assume no other income, no student loan repayments and no benefits interactions.
Sole Trader Paying a Spouse on No Other Income
You’re a higher-rate taxpayer and you pay £12,570 of profit through to your spouse as a genuine salary rather than taking it yourself. The effect on each side:
- Your own income tax: Drops by around £5,028 (40% on £12,570).
- Your Class 4 NI: May also fall
- Your spouse’s tax bill: Nothing. The £12,570 sits within their Personal Allowance and at the £12,570 Primary Threshold.
Net household position: around £5,800 a year less to HMRC in that specific case.
For a Scottish taxpayer, the equivalent calculation may use the 42% higher, 45% advanced or 48% top rate depending on the band. The structure is the same; the figure changes.
Husband-and-Wife Company Paying Through Dividends
Two directors each take a £12,570 salary plus dividends, with the Employment Allowance covering employer NI and dividends split 50/50 by shareholding:
- Company profit needed: Around £122,000.
- Household net income produced: Roughly £92,000.
- Tax position: All dividends sit within the basic rate band, using both spouses’ allowances.
Compared with one director taking everything personally, the household keeps £3,000 to £5,000 more, depending on profit level and other income.
Adult Child Working Part-Time During University
A 19-year-old works 15 hours a week for the family business at the £10.85 minimum wage band:
- Annual earnings: Roughly £8,460.
- Their tax bill: Nothing – it sits below the £12,570 Personal Allowance.
- The parent’s position: £8,460 of profit they’d otherwise have taken at the higher rate now sits with the child, leaving around £3,384 less tax in the household.
Higher Earner Using a Genuine Spouse Salary Around the £100,000 Taper
A sole trader’s profits are heading for £108,000 – into the band where the Personal Allowance tapers away at a 60% effective rate. They pay £8,000 of profit through to their spouse as a genuine salary covering 14 hours a week of admin and bookkeeping:
- Their own adjusted net income: Drops from £108,000 to £100,000, restoring £4,000 of the Personal Allowance (the allowance tapers by £1 for every £2 over £100,000).
- Their tax saving: Around £4,800 of income tax – £3,200 from removing £8,000 from the 40% band, plus £1,600 from the £4,000 of allowance recovered. Class 4 NI may also fall depending on the profit band.
- Their spouse’s tax bill: Nothing – the £8,000 sits well within the Personal Allowance.
Household position: roughly £4,800 less income tax to HMRC, before any NI effect.
Retired Parent Helping Out Part-Time
A parent over State Pension age does 8 hours a week of bookkeeping for their adult child’s sole trader business at £15 an hour – about £6,240 a year:
- Their tax bill: Modest. The State Pension uses part of their Personal Allowance, leaving around £5,000 of unused allowance to cover most of the wage. They pay 20% on roughly £1,200 of taxable income – around £240.
- NI position: The parent pays no employee NI once over State Pension age. Employer NI may still be due above the £5,000 Secondary Threshold, unless covered by Employment Allowance or another relief. On £6,240 of pay, that would be around £186.
- The business owner’s position: £6,240 of deductible expense saves around £2,500 in income tax at the 40% rate.
Household position: around £2,070 less to HMRC, after factoring in the employer NI cost.
The figures change with rates, ages and circumstances, but the structural logic holds. The catch is that HMRC has been watching these arrangements for decades, and the rules on what counts as a deductible expense are tight.
What to Have in Place
A short checklist of what makes a family employment arrangement defensible:
- A written employment contract with the job role, hours and pay rate
- PAYE and NI properly operated through compatible payroll software, with payslips issued each month
- Evidence of work done – time logs, project records, emails, work produced
- A pay rate that matches a third-party rate for the same work
- Pension auto-enrolment assessed for every family employee
- Shareholdings with full voting and dividend rights, not a separate “dividend-only” class
Where these are in place, the arrangement is much more defensible if HMRC reviews it. Where they’re missing, family employment can produce expensive surprises.
How Double Point Can Help
Properly employing family members is one of the higher-impact areas of owner-managed business tax planning, but it requires careful setup.
The savings can run to several thousand pounds per family member per year, and the cost of getting the structure right is normally a small fraction of the tax saved.
This guide is general information only, not personal tax advice. The right structure depends on the family member’s role, pay, other income, benefits position, company profits and eligibility for reliefs.
At Double Point, our chartered accountants help business owners across the UK set up commercially defensible family employment arrangements – assessing the right structure, handling the PAYE and NI machinery, structuring shareholdings, and reviewing arrangements annually as the rules change.
