Income shifted to a minor child is taxed back on you but if they are under 18 they cannot legally be partners in a partnership. Used properly, a family LLP is a planning tool. Used as a tax avoidance scheme, it is a liability.
Key Takeaways
- An LLP shares rental profit by your partnership agreement, not by the rigid 50:50 default that applies to property jointly owned by a married couple.
- A genuine outright gift of a real LLP interest to your spouse is generally protected from the settlements rules by ITTOIA 2005, Section 626.
- Rental income passed to a minor child is taxed back on you above £100 a year under ITTOIA 2005, Section 629, as of the 2026 to 2027 tax year.
- Moving property into a family LLP without doing it properly can trigger Stamp Duty Land Tax and Capital Gains Tax, even between connected family members.
Key definitions
Limited liability partnership (LLP). A business structure created under the Limited Liability Partnerships Act 2000. It is a separate legal entity, but for income tax it is transparent: each member is taxed on their share of the profit.
Settlements legislation. Anti-avoidance rules in ITTOIA 2005, Part 5, Chapter 5. They tax income back on the person who diverted it where an arrangement gives away income while keeping a benefit.
Why do property landlords use an LLP to split rental income?
An LLP lets you allocate rental profit between members by your partnership agreement, not by legal ownership. For property held personally by a married couple, income is split 50:50 by default under the Income Tax Act 2007, Section 836. Form 17 only lets you reflect genuine unequal ownership, so a partnership offers more flexibility.
The attraction is the gap between two regimes. Outside a partnership, a married couple is taxed 50:50 on jointly held property whoever owns it, unless they file Form 17 to be taxed on their real, evidenced shares. Inside a genuine partnership, profit follows the agreement, so a higher-rate partner can take less and a basic-rate partner more.
The main routes compared
| Route | How income is split | Key catch |
|---|---|---|
| Jointly held (married) | 50:50 by default; Form 17 for actual shares | Form 17 must reflect genuine unequal ownership |
| Family LLP (individuals) | By the partnership agreement | SDLT and CGT on entry; settlements rules apply |
Can you split rental income with your spouse through an LLP?
Yes, where you make a genuine outright gift of a real LLP interest to your spouse or civil partner. ITTOIA 2005, Section 626 exempts outright gifts between spouses from the settlements rules, provided the gift is the whole interest and not merely a right to income.
The leading authority is Jones v Garnett, the Arctic Systems case, which confirmed the spouse exemption protects a genuine gift of a real stake with full rights to capital and income. The risk is structuring your spouse’s share as income only, or as a paper entitlement. That falls outside the exemption, and HMRC can tax the income back on you.
Can you split rental income with your children through an LLP?
Only with adult children. Under ITTOIA 2005, Section 629, rental income passed to your unmarried minor child is taxed as yours above £100 a year. There is no spouse-style exemption for children, so a minor cannot be used to shelter rental profit.
For a child aged 18 or over, Section 629 no longer bites, so a genuine gift of an LLP interest can move income to them. The adult child must genuinely own the stake and receive the profit, and you must not keep the benefit, or the retained-interest rule in Section 624 applies.
What does it cost to move property into a family LLP?
Transferring personally held property into an LLP is a tax event, not a free reshuffle. It can trigger Stamp Duty Land Tax under Schedule 15 of the Finance Act 2003, and Capital Gains Tax on a part disposal at market value, even between connected family members – unless its done correctly.
Expert Perspective: what most people get wrong
The biggest mistake is treating the LLP as a switch you can flick to reallocate profit each year, for free. Because a buy-to-let LLP is a property investment partnership, changing the income profit shares can itself be a chargeable transfer for Stamp Duty Land Tax.
The second mistake is the “hybrid” version, where a company is added as a corporate member to soak up profit at corporation tax rates and sidestep the mortgage interest restriction. HMRC set out in Spotlight 63, escalated by Spotlight 63A in April 2026, that this does not work. The mixed member partnership rules in ITTOIA 2005, Sections 850C and 850D reallocate the excess profit straight back to you.
Used honestly, a family LLP is a genuine structure. 19 out of 20 Bluebond clients legitimately pay zero inheritance tax, through arrangements with real substance, not schemes that unravel on enquiry.
A practical checklist before you set up a family LLP
- Does your letting activity amount to a genuine business with a view to profit, not passive co-ownership?
- Is each family member a real member of the LLP, sharing in capital, profit and obligations?
- Are your children 18 or over, so the parental settlement rule in Section 629 does not apply?
- Does the profit split reflect genuine ownership and contribution, not a paper diversion of your income?
What to Avoid
- Adding a limited company as a corporate member to escape the mortgage interest restriction. HMRC treats this as ineffective.
- Giving a minor child a profit share to shelter rental income. It is taxed back on you above £100 a year.
- Setting up the LLP days before a transfer to claim SDLT relief. HMRC can disregard a paper partnership.
- Allocating your spouse income only, with no real stake. That loses the Section 626 spouse exemption.
- Flipping profit shares each year without checking the Stamp Duty Land Tax consequences.
Frequently asked questions
Property & Business
Does moving property into an LLP remove the mortgage interest restriction?
No reliable route does this through a corporate member. HMRC challenges hybrid LLP arrangements that allocate profit to a company to bypass the finance cost restriction, under Spotlight 63 and 63A. A genuine all-individual family LLP does not remove the restriction; it changes who is taxed on the profit.
Can I use Form 17 instead of an LLP to split income with my spouse?
Form 17 lets married couples be taxed on their actual, unequal shares of jointly held property rather than 50:50. It reflects real ownership only, so you cannot pick any ratio. An LLP shares profit by agreement instead, but adds its own SDLT, CGT and anti-avoidance points.
Is a married couple who own a rental property automatically a partnership?
No. Joint ownership is not a partnership. HMRC taxes a married couple 50:50 on jointly held property under the Income Tax Act 2007, Section 836, unless Form 17 reflects genuine unequal ownership. A partnership exists only where a real business is run together with a view to profit, with accounts and an agreement.
Where this leaves you
A family LLP can be a legitimate way to share rental profit across people on different tax rates and to pass a portfolio down a generation. It rewards substance and punishes shortcuts. A sound structure comes down to whether the business is real, the gifts genuine, and the entry costs modelled before anyone signs.
