Joint Ventures in Property Development: LLP vs Company, and the Tax That Follows

A landowner with a site and no build experience. A developer with the skill and no site. Two developers pooling capital to take on something neither could carry alone. Property joint ventures are usually a good commercial idea. The vehicle you put around them — LLP or limited company — changes who pays tax, when they pay it, and how much lands on the land itself before a spade goes in.

The two vehicles in practice

Almost every genuine JV between two parties who each bring something to a development ends up in one of two shapes: a Limited Liability Partnership (LLP) with each party as a member, or a joint venture company owned by both parties (often via their own holding companies) under a shareholders' agreement. Both give limited liability. The tax treatment is where they diverge sharply.

The LLP: transparent, and taxed as it arises

An LLP pays no tax itself. Each member is taxed individually on their share of the LLP's profit, in line with the profit-sharing ratio set out in the LLP agreement, and that tax is due as the profit arises — not when it is actually drawn out. Individual members pay income tax and Class 4 National Insurance on their share; a corporate member pays corporation tax on its share under the normal rules.

That last point is why a lot of development JV LLPs have a corporate member sitting alongside the individuals: allocating profit to a company inside the LLP accesses corporation tax rates rather than income tax rates on that slice of profit. It is a legitimate structure, used constantly. It is also exactly the arrangement HMRC's mixed membership partnership rules were written to police.

The mixed membership trap

Where an LLP has both individual members and a corporate member, and profit is allocated to the corporate member beyond what its actual capital contribution and commercial risk in the venture justify, HMRC can reallocate the excess back to the individual members and tax it as their personal income — at their own rates, as if the corporate member had never been allocated it. The rules exist specifically to stop profit generated by an individual's work being parked in a lightly-taxed corporate member with no real economic claim to it.

The practical fix is straightforward in principle: the corporate member's share of profit needs to be defensible by reference to what it has actually put in and what it is actually exposed to, not simply set at whatever level minimises the group's overall tax bill. Get the allocation agreed and documented properly at the outset, because retrofitting a justification after HMRC asks the question is a much harder conversation.

SDLT when land goes into an LLP

When a landowner contributes their site into a JV LLP in exchange for a membership interest, it is a land transaction, but not a full market-value charge in the way an outright sale would be. Special partnership rules relieve the contributing partner's own effective share of the value they are putting in. In broad terms, a landowner taking a 50% interest in the LLP is treated as having "kept" half the value for SDLT purposes and transferred the other half to their new partner — so SDLT is generally due on roughly half the land's market value, not the whole amount. The precise figure depends on the capital and profit shares actually agreed, and gets more involved where the shares are asymmetric or change over time, so it needs calculating properly rather than assumed at 50%.

The same logic runs in reverse if land is later distributed out of the LLP to one member rather than sold to a third party — a further SDLT event can arise on the share moving to whoever ends up owning it.

The company JV: no partnership relief, full value on the way in

Put the same land into a joint venture company instead, and the partnership SDLT relief does not apply at all. The land transfer is generally charged to SDLT on its full market value, the same as a sale to any unconnected third party, because a company is a separate legal person and the landowner is disposing of the asset entirely, not retaining an effective share of it. Group relief, which can shelter transfers between companies from SDLT, is not available here either — it requires at least 75% common ownership between the companies involved, and a genuine JV between two independent parties essentially never has that.

The landowner also has a disposal to deal with on their own side — typically Capital Gains Tax if the land was held as an investment, or a trading profit if it was held as stock — the same distinction covered in our guide to trading vs investment and the badges of trade.

Profit and VAT inside a company JV

A JV company pays corporation tax on its own profit as a single entity, then extracting that profit to the two shareholders is a further step: dividends between UK companies are generally tax-free, but a dividend reaching an individual shareholder is taxed as dividend income in their hands. For VAT, the JV company is its own taxable person and registers and recovers VAT on its own supplies in the normal way; VAT grouping with either partner's existing VAT group is not usually available, since grouping requires common control of both entities, and independent JV partners rarely have that over each other's businesses.

So which one fits?

An LLP tends to suit a JV where the parties want profit taxed and available as it is earned, where the mix of individual and corporate involvement can be structured and documented properly from day one, and where the parties are comfortable with the added complexity of partnership SDLT and mixed membership planning. A company JV tends to suit parties who want a cleaner, more familiar governance structure, an easier route to bring in institutional finance, and a straightforward share sale as the exit — accepting the two-layer tax cost of extracting profit and the full SDLT charge on the way in.

Neither is right by default. The answer follows from who is actually involved, how the deal is funded, and what the exit is meant to look like — questions worth working through under our Property Advisory service before the JV agreement is drafted, not after. For the single-owner version of this question, see our guide to when an SPV makes sense for a property project.

Common questions

Is an LLP or a limited company better for a property development joint venture?

It depends on who is involved and how the profit needs to flow. An LLP is tax-transparent, so members are taxed individually on their profit share as it arises, which suits parties who want profit as it is earned. A joint venture company is a single taxable entity paying corporation tax, which suits parties who want limited liability with cleaner governance and an easier exit by selling shares. Neither is universally better; the right answer depends on the parties, the funding and the exit plan.

Do I pay SDLT when a landowner puts land into a joint venture LLP?

Usually, but not on the whole value. Special partnership SDLT rules relieve the contributing partner's own effective share of the land, so a landowner taking a 50% interest in the LLP typically faces an SDLT charge on roughly the other 50%, based on the land's market value, not the full value as if selling outright. The exact calculation depends on the profit and capital sharing ratios agreed.

What are the mixed membership partnership rules?

They are HMRC anti-avoidance rules aimed at LLPs with both individual and corporate members, where profit is allocated to the corporate member to access corporation tax rates rather than income tax. If the allocation to the corporate member is more than its capital and risk in the venture justify, HMRC can reallocate the excess back to the individual members and tax it as their personal income.

Does a joint venture company get SDLT group relief on land going in?

Generally not. Group relief requires at least 75% common ownership between the companies involved, which a genuine joint venture between two independent parties rarely has. Land transferred into a JV company is usually charged to SDLT on its full market value, the same as a sale to any third party.
