Employing Your Spouse in Your Limited Company: The Complete Tax-Saving Guide

Employing your spouse in your UK limited company is one of the most effective tax-saving strategies available to small business owners. Done correctly, it can save your household thousands of pounds in tax each year whilst providing genuine benefits to your business.

The bottom line: If your spouse has no other income and performs genuine work for your company, paying them a salary of £12,570 uses their full Personal Allowance tax-free. Combined with Employment Allowance eligibility, this straightforward arrangement can reduce your total tax bill by £3,000-£6,000+ annually.

This guide covers everything you need to know: HMRC's rules, realistic salary levels, pension strategies, and the documentation required to keep your arrangement bulletproof.

Why Employ Your Spouse? The Tax Benefits Explained

When your spouse has unused tax allowances sitting idle, employing them shifts income from your higher-taxed position to their tax-free or lower-taxed position. This is completely legitimate income splitting.

The Core Tax Savings

Without employing your spouse, their Personal Allowance goes unused. Every pound you extract as additional dividends above the basic rate threshold is taxed at 33.75%. But pay your spouse instead? That same £12,570 costs zero income tax.

Why This Strategy Is So Powerful

The mathematics are compelling because you're doing three things simultaneously:

1. Using otherwise wasted allowances - Your spouse's £12,570 Personal Allowance would otherwise sit unused
2. Reducing your dividend tax - Lower company profits mean lower dividends, keeping you in basic rate territory
3. Unlocking Employment Allowance - Sole directors cannot claim this £10,500 NI relief; employers can

HMRC's Rules: Must Be Genuine Work for Genuine Pay

HMRC has no objection to family employment. Thousands of UK businesses legitimately employ spouses. However, they have clear requirements that must be met.

The Two Fundamental Requirements

1. Genuine Work Your spouse must perform actual, identifiable work that benefits the business. This cannot be fabricated or token tasks. The work should be something you would otherwise pay someone else to do or do yourself.

2. Commercial Pay The salary must be reasonable for the work performed. Ask yourself: "What would I pay an unrelated person for this exact role and these hours?" If you cannot justify the salary in those terms, it is too high.

What HMRC Considers Red Flags

HMRC investigators are experienced at spotting arrangements that exist purely for tax purposes. Warning signs include:

• No evidence of work performed - No emails, documents, or tangible output
• Salary disconnected from hours - £12,570 for "a few hours a week" raises questions
• Role has no substance - Vague responsibilities like "general assistance"
• No qualifications for complex roles - Marketing director with no marketing experience
• Payment patterns - Large payments coinciding with year-end
• Sudden implementation - Arrangement starts immediately after profits increase

The good news? If your arrangement is genuine, you have nothing to worry about. Document properly from day one and you will be fine.

What Counts as Genuine Work

Your spouse can legitimately perform many roles. The key is matching their actual skills and availability to real business needs.

Common Roles HMRC Accepts Without Question

Tasks Spouses Commonly Perform

Here are specific, tangible tasks that justify employment:

Financial Administration

• Processing invoices and sending payment reminders
• Reconciling bank accounts monthly
• Organising receipts and expense claims
• Preparing documents for the accountant
• Chasing late payments

Business Operations

• Managing email inbox and correspondence
• Scheduling meetings and calls
• Booking travel and accommodation
• Maintaining filing systems
• Ordering supplies and managing stock

Marketing and Sales

• Posting on social media channels
• Writing blog posts or newsletters
• Responding to enquiries
• Updating website content
• Managing online reviews

Customer Relationships

• Answering customer calls
• Processing orders
• Handling complaints
• Following up on deliveries
• Conducting satisfaction surveys

Realistic Salary Levels HMRC Will Accept

The salary must be justifiable. HMRC compares what you pay to market rates for similar roles. Here is a reality check on what is defensible.

Salary vs Hours: What Is Realistic?

At roughly £12-15 per hour for administrative work (above minimum wage, below specialist rates), you can see how the numbers add up. A spouse working 8-10 hours weekly at £14/hour justifies approximately £5,800-£7,300 annually.

The £12,570 Question

Many directors want to pay exactly £12,570 to use the full Personal Allowance. This is fine - but you need to justify it.

£12,570 is defensible when:

• Your spouse works approximately 15-20 hours weekly on substantive tasks
• They have relevant skills (bookkeeping qualification, marketing experience, etc.)
• You can demonstrate consistent output throughout the year
• The role is clearly defined with specific responsibilities

£12,570 raises questions when:

• Hours worked are vague or minimal (under 8 hours weekly)
• There is no evidence of actual work output
• The arrangement started only recently with a conveniently round salary
• Your spouse has no relevant skills for the stated role

If in doubt, pay what the work genuinely justifies. A salary of £8,000 for 8 hours weekly is more defensible than £12,570 for unclear duties.

The Optimal Spouse Salary: £12,570 Explained

For most couples where the spouse has no other income, £12,570 hits the optimal point. Here is why this number works.

The £12,570 Sweet Spot

At £12,570:

• Your spouse pays zero Income Tax (full Personal Allowance used)
• Your spouse pays zero Employee's NI (exactly at the threshold)
• They earn a full State Pension qualifying year (above £6,725)
• Your company claims Corporation Tax relief of £3,142.50 (£12,570 at 25%)

The Employer's NI Cost

The one cost is Employer's National Insurance at 15% on earnings above £5,000:

Employer's NI calculation: (£12,570 - £5,000) × 15% = £1,135.50

This cost is offset by Employment Allowance if you qualify (see next section). Even without Employment Allowance, the £1,135.50 cost is far outweighed by the tax savings achieved.

Using Employment Allowance When You Have Employees

Employment Allowance is a game-changer for small businesses. It provides up to £10,500 off your annual Employer's National Insurance bill for 2025/26.

Eligibility Rules

You CAN claim Employment Allowance if:

• You have at least one employee (including your spouse) earning above £5,000
• Your total Employer's NI bill in the previous year was under £100,000
• Your business is not primarily providing personal services where the worker would be an employee of the client (certain IR35 restrictions apply)

You CANNOT claim if:

• You are a sole director with no other employees
• Your only employees earn below £5,000 annually
• You are a public body or primarily funded by public sector

Why Employment Allowance Matters

As a sole director, you pay Employer's NI with no offset. The moment you employ your spouse (or any employee), you can claim Employment Allowance.

Sole director scenario:

• Director's salary: £12,570
• Employer's NI: £1,135.50
• Employment Allowance: £0 (not eligible)
• Net Employer's NI cost: £1,135.50

Director plus spouse employee:

• Director's salary: £12,570 → Employer's NI: £1,135.50
• Spouse's salary: £12,570 → Employer's NI: £1,135.50
• Total Employer's NI: £2,271
• Employment Allowance: -£2,271
• Net Employer's NI cost: £0

By employing your spouse, you eliminate Employer's NI entirely whilst extracting an additional £12,570 from the company tax-efficiently.

Pension Contributions for Spouse: Double the Tax Efficiency

Employer pension contributions for your spouse represent one of the most tax-efficient ways to extract value from your company.

How Employer Pension Contributions Work

When your company makes pension contributions for your spouse:

Worked Example: £5,000 Employer Pension Contribution

Cost to company:

• Pension contribution: £5,000
• Corporation Tax relief (25%): -£1,250
• Net cost: £3,750

Value to spouse:

• Pension pot receives: £5,000
• Tax paid: £0
• Net value: £5,000

For a net cost of £3,750, your spouse receives £5,000 in their pension. That is an immediate 33% return before any investment growth.

Combining Salary and Pension

The optimal approach often combines salary and pension contributions:

Your company saves 25% Corporation Tax on the combined £17,570 (saving £4,392.50) whilst your spouse receives £12,570 cash and £5,000 pension value, all with zero personal tax.

Annual Allowance Considerations

Employer pension contributions count towards the £60,000 Annual Allowance, but this is rarely a constraint for spouse employment scenarios. If your spouse has low or no earnings, they can still receive up to their "relevant UK earnings" in employer contributions, plus an additional £3,600 gross in personal contributions even with no earnings.

Worked Example: £60k Profit, With and Without Spouse Employed

Let us work through a complete comparison showing the real-world impact.

Assumptions

• Company profit before any salaries: £60,000
• Director has no other income
• Spouse has no other income
• Both are basic rate taxpayers for any dividends taken
• Corporation Tax rate: 25% (small profits rate for simplicity)

Option A: Director Only (No Spouse Employment)

The Comparison

By employing your spouse at £12,570, your household saves £3,609 in tax and takes home an additional £4,745 annually. The extra benefit comes from qualifying for Employment Allowance (£2,271 saving) plus using your spouse's Personal Allowance.

What Records to Keep

Documentation is your protection. If HMRC enquires, comprehensive records demonstrate legitimacy.

Essential Employment Documentation

Employment contract - Include:

• Job title and reporting structure
• Start date
• Salary and payment frequency
• Working hours (be specific)
• Holiday entitlement
• Notice period
• Duties and responsibilities

Job description - Cover:

• Role purpose and objectives
• Key responsibilities (minimum 5-6 specific items)
• Required skills or qualifications
• Working pattern
• Who they report to

Ongoing Records to Maintain

What Timesheets Should Include

A simple timesheet recording:

• Date
• Hours worked
• Brief description of tasks completed
• Running total

This does not need to be elaborate. A simple spreadsheet updated weekly showing "Monday 2 hours - processed invoices and reconciled bank account" is sufficient.

Retention Period

Keep all employment records for at least 6 years after the tax year they relate to. HMRC can open enquiries within this window.

Paying Spouse Dividends as Shareholder

If your spouse is also a shareholder, they can receive dividends in addition to salary. This creates additional income-splitting opportunities.

The Dividend Advantage

Dividends are taxed at lower rates than salary for amounts above the Personal Allowance:

Combining Salary and Dividends

If your spouse is a shareholder, the optimal extraction might be:

For a spouse with no other income and holding shares, they could receive:

• £12,570 salary (tax-free)
• £500 dividends (tax-free allowance)
• £37,200 further dividends at 8.75% basic rate

Total potential extraction: £50,270 before hitting higher rate tax. However, this requires substantial company profits and shareholding to support it.

Making Spouse a Shareholder: Considerations

Giving your spouse shares unlocks dividend payments, but requires careful thought.

Benefits of Spouse Shareholding

• Dividend income splitting - Both spouses use their allowances and basic rate bands
• Demonstrates commitment - Shows genuine involvement beyond just employment
• Future planning - Shares already held for potential business sale

Risks and Considerations

Settlements Legislation (Income Tax Act 2007)

The "settlements legislation" can attribute income back to you if:

• The arrangement is primarily for tax avoidance
• Your spouse has no genuine involvement in the business
• The shares were gifted specifically to split income

Following the landmark Arctic Systems case (2007), the courts ruled that ordinary husband-wife share arrangements are generally acceptable where the spouse has genuine involvement. However, the legislation remains on the books and HMRC occasionally challenges arrangements.

Generally Safe:

• Spouse actively works in the business
• Shares held from company formation or early stage
• Spouse has relevant skills and genuine input
• Commercial rationale beyond tax

Higher Risk:

• Spouse has zero involvement beyond receiving dividends
• Shares transferred recently coinciding with profit increase
• No evidence of contribution to business success
• Disproportionate dividend allocation vs work contribution

Practical Recommendations

If considering spouse shareholding:

1. Document their contribution - Work performed, decisions contributed to
2. Consider timing - Earlier is better than waiting until profits spike
3. Be proportionate - 50/50 shareholding with zero spouse involvement is riskier than 80/20 with genuine involvement
4. Take advice - For significant shareholding transfers, professional advice is worthwhile

Childcare and Household Tasks: What HMRC Accepts and Does Not

A common question: can you pay your spouse for looking after children or maintaining the household, freeing you to work?

The Short Answer: No

Domestic tasks - childcare, cleaning, cooking, household management - are not business expenses, even if they indirectly enable you to work. HMRC does not accept these as legitimate business activities.

What Is Not Acceptable

What Is Acceptable

Your spouse can be paid for genuine business tasks, even if performed from home:

The key distinction: is the task directly for the business (acceptable) or for the household/family (not acceptable)?

The Exception: Registered Childcare

If your spouse is a registered childminder or runs a nursery as a separate business, you could pay for childcare at commercial rates. But this is not employment - it is a business-to-business transaction with appropriate invoices and their own tax obligations.

Common Mistakes That Trigger HMRC Enquiries

Learn from others' errors. These mistakes draw HMRC attention:

1. No Evidence of Actual Work

The mistake: Paying a salary with no documented output.

The fix: Keep timesheets, save work samples, maintain email records showing involvement.

2. Salary Does Not Match Hours

The mistake: £12,570 salary for "helping out occasionally."

The fix: If the salary is £12,570, demonstrate 15-20 hours weekly of substantive work. If hours are lower, pay a proportionate amount.

3. Suspiciously Convenient Timing

The mistake: Implementing spouse employment in March after a record profit year.

The fix: Set up employment arrangements at the start of a tax year, not the end. Document the business rationale.

4. No Employment Contract or Job Description

The mistake: Treating it casually because "we are married."

The fix: Create proper employment documentation as you would for any employee.

5. Cash Payments

The mistake: Paying in cash with no paper trail.

The fix: Always pay by bank transfer. Maintain payslips and clear bank records.

6. No Payroll Compliance

The mistake: Failing to register as employer, submit RTI, or issue payslips.

The fix: Register with HMRC, run proper payroll, submit Real Time Information reports each pay period.

7. Overpaying for the Role

The mistake: Paying £25,000 for basic admin work.

The fix: Research market rates. Pay what you would pay an unrelated person.

8. Spouse Cannot Do the Claimed Role

The mistake: "Marketing Director" salary for someone with no marketing experience.

The fix: Match the role to their actual skills. Administration and bookkeeping are believable for most people; specialist roles need justification.

Frequently Asked Questions

Is it legal to employ my spouse in my limited company?

Yes, employing your spouse is completely legal and is a widely-used, legitimate tax planning strategy. HMRC accepts family employment arrangements provided the work is genuine and the pay is commercially reasonable for the work performed. Thousands of UK small businesses employ family members.

What is the optimal salary to pay my spouse?

If your spouse has no other income, £12,570 uses their full Personal Allowance, resulting in zero Income Tax and zero Employee's National Insurance. This requires approximately 15-20 hours weekly of genuine work to be defensible. If their work justifies less, pay a proportionate amount.

Will HMRC investigate if I employ my spouse?

HMRC does not automatically investigate family employment, but may enquire if the arrangement appears artificial. Maintain proper documentation - employment contract, job description, timesheets, work evidence - and you have nothing to worry about. Genuine arrangements with reasonable pay are accepted without issue.

Can my spouse work from home?

Yes, your spouse can work from home. Many legitimate roles - bookkeeping, administration, customer service, marketing - are performed remotely. The location does not affect legitimacy; the work and documentation do.

Do I need to pay my spouse the National Minimum Wage?

Yes, all employees including family members must receive at least National Minimum Wage (£11.44/hour for over-21s in 2025/26). However, if paying a salary around £12,570 for genuine part-time work, you will typically exceed minimum wage requirements.

Can I backdate spouse employment?

No, you cannot backdate employment. HMRC requires contemporaneous records. You can only claim tax relief for salary paid during periods when your spouse was genuinely employed and performing work.

What if my spouse already has a job?

If your spouse is employed elsewhere, their Personal Allowance may already be used. Calculate their remaining allowance before setting a salary. Additional salary above the Personal Allowance incurs 20% Income Tax and 8% Employee's NI, which may still be tax-efficient depending on your circumstances.

Can I employ my spouse if we do not live together?

Yes, you can employ a spouse regardless of living arrangements. Married or civil partner status is not required either - you can employ any partner performing genuine work. The same rules apply: genuine work, reasonable pay, proper documentation.

Should my spouse be an employee or director?

For most small businesses, employee status is simpler. Director status involves Companies House registration and additional duties. Make your spouse a director only if they are genuinely involved in running the business and you want them to have formal decision-making authority.

What happens if HMRC disallows the salary?

If HMRC successfully argues the salary was not for genuine work, the company loses the Corporation Tax deduction. You would owe additional CT plus interest. Penalties may apply if HMRC considers the arrangement careless or deliberate. However, well-documented genuine arrangements are rarely challenged.
