Can I Pay My Spouse a Salary to Reduce My Tax Bill?
For small business owners, especially those running limited companies or sole traderships, the question of whether they can legally pay their spouse a salary is a common one — and it’s an important one, too. Done correctly, employing your spouse can lead to genuine tax savings. But done improperly, it can raise red flags with HMRC and lead to costly consequences.
At Merranti Accounting, we frequently advise clients on this subject, and in this article, we’ll explore the full picture. We’ll look at the legality of paying your spouse, how to do it in a compliant way, the tax implications, and the potential benefits — all without triggering unnecessary scrutiny from HMRC.
Is It Legal to Pay Your Spouse Through Your Business?
In short, yes — it is entirely legal to pay your spouse or civil partner a salary through your business. But there is a vital caveat: the arrangement must be commercial, genuine, and correctly documented.
HMRC allows spouses or family members to work in a business and be paid just like any other employee. However, because of the personal relationship, HMRC expects the arrangement to stand up to greater scrutiny. This means the work must actually be performed, the rate of pay must be commercially reasonable, and proper records must be maintained to prove the employment relationship is genuine.
You can’t simply name your spouse on your payroll to reduce your tax bill if they’re not contributing in any real way to the business.
What Kind of Work Can a Spouse Do?
The scope here is wide. Your spouse does not need to perform technical or highly skilled duties — they simply need to contribute meaningfully to the business. Many small businesses involve their spouse in administrative tasks, customer service, marketing, or even practical help like stocktaking or delivery.
Some common roles might include basic bookkeeping, data entry, scheduling appointments, updating the website, handling customer enquiries, or managing email communication. Even tasks such as packing orders, doing inventory checks, or helping with general admin are acceptable — provided the work is real and the business benefits from it.
What matters is not the complexity of the job, but that it actually exists, is performed, and provides a commercial benefit.
How Much Should I Pay Them?
One of the most frequent mistakes business owners make is paying an arbitrary amount to their spouse without evidence of the work done. The amount paid must reflect the nature of the work, the time commitment involved, and what you would pay someone else to do that job.
For example, if your spouse spends five hours per week helping with admin tasks, it would be reasonable to pay them an hourly rate consistent with that type of work in your industry and location. Paying them a full-time manager’s salary for minimal or sporadic duties could trigger an investigation and lead to HMRC denying the expense as a valid business cost.
Some business owners opt to pay their spouse up to the National Insurance lower earnings limit (which for 2025/26 is £6,396 annually) so that the salary doesn’t attract NI or income tax but still entitles the spouse to National Insurance credits. Others pay just below the personal allowance (£12,570), enabling the spouse to receive a tax-free salary while the business gets full corporation tax relief on the wages.
But again, it all depends on whether the work performed justifies the level of pay.
Do I Need to Register as an Employer?
If you’re operating as a sole trader and want to employ your spouse, you will likely need to register as an employer with HMRC if you’re paying them more than the lower earnings limit. This means running a payroll, issuing payslips, reporting through Real Time Information (RTI), and ensuring all employer obligations are met.
For directors of limited companies, the process is already built into the structure, and adding your spouse to the company payroll is relatively straightforward — but again, it must be properly documented and reported.
Can I Combine Salary with Dividends?
If your spouse is also a shareholder in your limited company, then a combination of salary and dividends might be an option. Dividends are paid from post-tax profits and aren’t considered business expenses, so they don’t reduce your corporation tax bill — but they are often taxed at a lower rate than salary income.
However, to pay dividends, your spouse must own shares in the business, and you must distribute dividends in line with shareholdings. You can’t simply assign arbitrary dividend payments without observing legal and procedural requirements, such as declaring dividends through board minutes and issuing proper dividend vouchers.
Also, be cautious around “income shifting.” If you give your spouse shares and dividends primarily to reduce tax, HMRC could invoke the settlements legislation, particularly if your spouse isn’t actively involved in the business or didn’t pay for the shares.
What Records Should I Keep?
Whether you’re paying your spouse a salary, dividends, or both, good record-keeping is essential. If HMRC queries the arrangement, you will need to demonstrate that the work was real and the payments were appropriate.
At a minimum, you should have:
- A formal employment contract
- A job description or summary of tasks performed
- Regular payslips and payroll records
- Evidence of work done (emails, schedules, timesheets, etc.)
- Accurate PAYE submissions if required
This not only protects you in the event of an enquiry but also ensures your spouse qualifies for any relevant benefits or credits.
Common Pitfalls to Avoid
Many business owners assume that simply making a payment to their spouse makes it tax-deductible. That’s not the case. If HMRC determines that the payments are not genuine or commercially justifiable, they can disallow the expense entirely — meaning your corporation tax or income tax bill will increase, and you may face penalties or interest on underpaid tax.
Some common errors include:
- Overpaying for minimal work
- Paying with no evidence of actual tasks
- Failing to register properly as an employer
- Not submitting PAYE reports
- Confusing dividends with salary
If there is any private benefit or attempt to disguise income, you may also fall foul of anti-avoidance legislation.
Does This Apply to Partnerships Too?
Yes. If you operate as a partnership, you can include your spouse as a partner, provided they play an active role in the business and the profit share reflects this.
However, HMRC may challenge profit allocations that are disproportionate to the spouse’s involvement. You’ll need to show that the division of profits is fair and commercially based.
