Are there tax advantages in transferring buy-to-let properties into a family LLP?

Introduction

Owners of long-held buy-to-let properties sometimes consider moving them into a limited liability partnership (LLP), especially where they want to involve a child in the family investment structure. A common question is whether that transfer creates any tax saving, particularly for stamp duty land tax (SDLT).

The answer is that an LLP can sometimes produce a low or nil SDLT charge where the same owners move property into the LLP and keep broadly the same economic interests. However, bringing in a new family member often changes the position and can trigger SDLT on part of the value transferred.

The Question

A married couple jointly own a number of residential buy-to-let properties that they have held for many years. They are considering transferring those properties into a newly formed LLP in which the members would be the couple and their adult child. They want to know whether there are any tax advantages in doing so.

Nick’s Explanation

Nick’s main point was that, for SDLT purposes, an LLP is generally treated under the partnership rules. The key issue is not simply that the properties are being moved into a new legal vehicle, but whether part of the economic ownership is being shifted to someone who did not previously own the properties.

In anonymised terms, his explanation was:

“The formation of an LLP and the transfer of land into that LLP are treated in the same way as partnerships. If the existing owners become partners and retain the same economic proportions as before, the SDLT charge can be minimal or nil. But adding a child as a member complicates matters, because SDLT is generally charged on the proportion of the property value treated as transferred to the other partner.”

He also noted that a precise answer depends on the detailed facts, including:

• the ownership shares before the transfer
• the profit-sharing and capital shares in the LLP
• whether the child is paying anything for the interest received
• whether there are mortgages on the properties
• whether partnership interests may change later

The Law

SDLT is charged on land transactions under Part 4 of Finance Act 2003.

• Section 42 Finance Act 2003 provides that SDLT is charged on land transactions.
• Section 43 Finance Act 2003 defines a land transaction as an acquisition of a chargeable interest.
• Section 48 Finance Act 2003 defines a chargeable interest as an estate, interest, right or power over land in England, subject to limited exceptions.

Where land is transferred into a partnership, including an LLP for these purposes, the special rules in Schedule 15 to Finance Act 2003 apply.

Paragraph 10 of Schedule 15 contains the main rule for transfers of land into a partnership by a person who is or becomes a partner. Instead of simply taxing the full market value in every case, the legislation uses a special calculation that broadly asks how much of the land has effectively moved to persons other than the transferor.

In broad terms:

• if the same person or persons transfer property into a partnership and keep the same underlying economic interests, the SDLT charge may be reduced substantially or eliminated
• if another partner acquires an economic share in the property, SDLT is usually charged by reference to that share

Schedule 15 also contains anti-avoidance and follow-on rules. Paragraphs 14 to 20 deal with situations such as later changes in partnership shares and arrangements that may produce further SDLT charges after the initial transfer.

Analysis

The practical tax analysis starts with the fact that a transfer from individual owners to an LLP is not ignored merely because the individuals remain involved. The legislation looks through the partnership structure and asks who economically owns what before and after the transfer.

Step one is to identify the current ownership. If the couple already own the properties equally, each has a 50% interest before any transfer.

Step two is to identify the proposed LLP shares. If, after the transfer, the couple and their child each hold some share in the LLP capital or in the underlying property economics, the child will usually be treated as acquiring part of the property interest.

Step three is to apply the Schedule 15 formula. If the couple alone transfer the properties into the LLP but the child becomes entitled to part of the LLP’s capital or value, SDLT is generally charged on the proportion of the market value regarded as passing to the child.

For example, if the child is given a genuine one-third economic stake in the LLP’s property value, the SDLT analysis will usually focus on that one-third shift. The result is not usually a tax-free transfer of the whole portfolio. Instead, there is often an SDLT charge on the part treated as moving from the parents to the child.

Step four is to consider debt. If the properties are mortgaged, the SDLT position may become more expensive. Assumption of debt or partnership arrangements involving debt can increase chargeable consideration.

Step five is to consider later changes. Even if the initial structure appears efficient, later movements in partnership shares can trigger further SDLT consequences under Schedule 15, particularly under paragraph 14 and related provisions.

It is also important to remember that SDLT is only one part of the tax picture. Depending on the facts, a transfer into an LLP may also raise capital gains tax issues and may not produce the income tax or inheritance planning benefits the owners expect. Those wider taxes are not answered by the SDLT rules alone.

Outcome

The practical conclusion is that there is no automatic tax advantage in transferring a family buy-to-let portfolio into a newly formed LLP.

If the same owners move the properties into the LLP and retain the same economic interests, the SDLT charge may be small or nil under Schedule 15. But if an adult child is introduced as a new member with a real share in the properties, SDLT will usually arise on the part of the value treated as transferred to that child.

So, in a typical family LLP arrangement of this kind, the introduction of the child is the feature most likely to create an SDLT charge rather than avoid one.

Practical Steps

Anyone considering this type of transfer should work through the following points before proceeding:

• confirm the exact legal and beneficial ownership of each property now
• set out the intended LLP profit shares, capital shares and winding-up entitlements
• check whether the child is receiving a genuine economic interest and, if so, how large it is
• review whether any mortgages exist and whether debt will be assumed or refinanced
• model the SDLT outcome under Schedule 15 before any documents are signed
• consider capital gains tax and any other tax consequences separately
• review whether future changes in partnership shares could trigger additional SDLT

In practice, the SDLT result depends heavily on the detailed numbers and on the drafting of the LLP arrangements. A proper calculation is usually needed before deciding whether the structure is worthwhile.

Conclusion

Transferring buy-to-let properties into a family LLP is not, by itself, a tax-saving step. For SDLT, the key question is whether any part of the underlying property value is being shifted to a new partner. If it is, SDLT will often be payable on that part. The more closely the LLP mirrors the existing ownership, the more likely it is that SDLT can be reduced or avoided.
