If you have been running a small freelance business or side hustle and your income is starting to grow, you may be exploring ways to manage your tax position more efficiently. One common question is whether you can share some of that income with your spouse or civil partner to reduce the overall tax bill. The answer is yes, but only if it is done correctly and within HMRC’s rules.
Below, we explain how income splitting works, why partnerships offer a practical solution, and what you need to have in place to stay compliant.
Why Income Splitting Is So Popular
Sharing income with your spouse or civil partner is one of the most widely used tax planning strategies. However, HMRC does scrutinise these arrangements closely.
For example, paying a spouse a salary when they are not genuinely working in the business or allocating them most of the dividends from a company can be challenged by HMRC. These artificial arrangements often do not stand up to review.
Partnerships, however, are treated differently.
Why Partnerships Are So Effective
Under English law, a partnership exists simply when two or more individuals share the profits of a business. That simplicity makes it difficult for HMRC to challenge the fact that a genuine partnership has been formed or how profits are shared between the partners.
In fact, HMRC’s own internal guidance confirms this, noting that while challenges are possible, they are “often very difficult to sustain”.
Tip: Always draw up a formal partnership agreement. It provides clear evidence of how the partnership operates and reduces the risk of HMRC challenge.
Does HMRC Accept Partnerships Formed Mainly to Save Tax?
Surprisingly, HMRC’s own guidance offers reassurance. It acknowledges that spouses or civil partners are sometimes added to a partnership wholly or mainly for tax planning reasons.
Crucially, HMRC also confirms:
• A partnership is not a sham simply because it creates a tax advantage.
• HMRC cannot challenge the allocation of profits in the way it might challenge a salary or wage.
• Profit apportionment is not judged by the value of each partner’s contribution to the business.
This gives partnerships a uniquely strong footing compared with other forms of income splitting.
The Trap: How Loss Relief Is Limited
Although HMRC generally accepts the use of partnerships for income splitting, it does apply stricter rules to losses.
If your spouse is not active in the business or only plays a limited role, special rules may restrict their ability to claim income tax relief on partnership losses.
This does not prevent the partnership from being effective, but it is important to be aware of the limitation.
Settlements Legislation: A Possible Catch
One other rule to understand is the settlements legislation. HMRC can use this to argue that profits paid to a spouse should instead be taxed on the other partner, but only in certain situations.
Thankfully, the legislation only applies if the spouse is entitled solely to income but does not have a share in the capital assets of the business. Capital assets include goodwill and any other underlying value of the business.
If your spouse has a genuine capital stake in the partnership, the settlement rules do not apply.
Tip: Make sure your partnership agreement clearly sets out each partner’s entitlement to both profits and capital.
How to Make Income Splitting Work for You
To legitimately share taxable income with your spouse through a partnership, you must:
• Form a genuine partnership in which profits are shared.
• Give your spouse a real share in the partnership’s capital assets, not just income.
• Document everything in a formal partnership agreement.
When these steps are followed, HMRC’s own guidance supports the arrangement and recognises it as a legitimate approach to tax planning.
You may also want to calculate the potential tax savings. Using an income-splitting tool or seeking professional advice can help you understand the impact before making any changes.
