Will SDLT apply if I move my home or business property into a limited company?

Introduction

People often ask whether moving a property into a limited company can avoid Stamp Duty Land Tax (SDLT), especially where they already own another dwelling or where a business property is currently held through a partnership or personally. Two common situations arise:

• buying a new home while still owning an existing one; and
• transferring a business property from a partnership or an individual into a company with similar ownership.

The answer depends on the exact legal structure. In many cases, transferring property into a company is itself a chargeable transaction for SDLT, and it does not solve the higher rates problem on a new residential purchase. For partnership incorporations, special SDLT rules may reduce or eliminate the charge, but only if the ownership positions genuinely match and the statutory conditions are met.

The Question

A reader asked about two linked SDLT issues.

First, if a person owns an existing home and wants to buy another dwelling to live in, can they avoid the higher residential SDLT rates by first transferring the original home into a limited company?

Second, if a business property is being moved from an existing business structure into a limited company, can that transfer be free of SDLT where the people behind the old structure and the new company are effectively the same? The facts then became more complicated because the property was owned by one individual, while the company ownership included that individual and their spouse.

Nick’s Explanation

Nick’s core view on the first point was straightforward: moving the original dwelling into a company would not solve the additional dwelling issue. In anonymised form, his explanation was that if you transfer your original property into a limited company, “it will be subject to stamp duty land tax charges” and “it will still be considered an additional property because you will retain ownership” for the purposes of the replacement rules unless the old main residence is actually disposed of in the required way.

On the second point, Nick explained that a transfer from a partnership to a limited company may fall within the special partnership rules in Schedule 15 Finance Act 2003. He summarised the position by saying that where the partnership and the company are effectively a mirror of each other in ownership terms, the transfer may be exempt or produce no effective SDLT charge because the “sum of the lower proportions” may be 100%.

He also identified the practical difficulty where the facts do not truly mirror each other. If the property is owned by one person, but the company is owned by that person together with a spouse, the analysis is no longer the simple mirror-image case. That means the special relief assumptions need much closer scrutiny.

The Law

The main residential higher-rates rules are in Schedule 4ZA to the Finance Act 2003. Broadly, higher rates can apply when a purchaser buys a dwelling and, at the end of the day of the transaction, has a major interest in another dwelling, unless an exception applies.

One of the main exceptions is where the new dwelling replaces the purchaser’s only or main residence. The statutory conditions include the disposal of the old only or main residence within the relevant three-year window and the intention that the new dwelling will be the new only or main residence.

The wording quoted in the source material reflects paragraph 3(6) of Schedule 4ZA Finance Act 2003, which sets out when a purchased dwelling counts as a replacement for the purchaser’s only or main residence.

For transfers involving partnerships, the relevant rules are in Schedule 15 to the Finance Act 2003. Paragraphs 18 to 20 contain special rules for the transfer of a chargeable interest from a partnership. These rules use the “sum of the lower proportions” or SLP calculation. In simplified terms:

• if the same people own the property economically before and after the transfer in the same proportions, the SLP may be 100%;
• if the SLP is 100%, the chargeable consideration can be reduced to nil under the statutory formula; and
• if the ownership proportions change, SDLT may arise on the part representing the change.

However, these rules are technical. They depend on the true legal ownership before the transfer, the relevant owners after the transfer, connected persons, and the exact proportions used in the statutory calculation.

Analysis

It helps to separate the two issues.

On buying a new home while still owning the old one, transferring the old home into a company does not usually achieve what many buyers hope.

1. The transfer of the existing dwelling into the company is normally itself a land transaction for SDLT purposes.
2. A company is a separate legal person. Moving the property into the company is not the same as simply putting the property “under” the same ownership.
3. If the individual then buys a new dwelling while the statutory replacement conditions are not met, the higher residential rates can still apply.
4. The usual route to avoiding or reclaiming the higher rates is the actual disposal of the previous only or main residence within the statutory time limit, not merely moving it into a company structure.

So, in practical terms, a buyer generally faces two choices:

• keep the old dwelling and accept that the higher rates may apply on the new purchase; or
• dispose of the old only or main residence and, if the timing works under Schedule 4ZA, either avoid the surcharge from the outset or reclaim it later.

Now take the business-property transfer point.

If a property is genuinely owned by a partnership and is transferred to a company owned by the same people in the same proportions, Schedule 15 may produce a favourable SDLT result. That is because the SLP calculation can reflect continuity of economic ownership.

But that favourable result depends on the actual legal and beneficial facts. A few key questions matter:

• Was the property truly partnership property, or was it legally and beneficially owned by one individual?
• Who were the partners immediately before the transfer?
• Who will own the company immediately after the transfer?
• Are the ownership proportions genuinely identical?
• Are any spouses or other connected persons involved in a way that changes the statutory calculation?

If the property is in one individual’s sole name, but the company is owned jointly by that individual and their spouse, that is not the simple “same people, same proportions” case. Even if the spouse resigns from the company before the transfer, the position still needs careful analysis because SDLT looks at the actual transaction, timing, ownership, and in some cases connected-person rules. It cannot safely be assumed that changing the company ownership shortly before the transfer will automatically produce a nil SDLT outcome.

Another important point is that the source material referred to the transfer as being “exempt” from stamp duty. Strictly speaking, the Schedule 15 rules do not create a general exemption in everyday language. Rather, they provide a special charging mechanism which may result in no effective charge if the statutory formula reduces the chargeable consideration appropriately.

Where readers are considering whether a property is residential because it is in poor condition or not fit for use as a dwelling, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. A property will not fall outside the dwelling rules merely because it needs work or is in disrepair. The courts now require a fairly serious level of unsuitability before the property will be treated as not suitable for use as a dwelling.

Outcome

The practical conclusion is this:

• Transferring an existing home into a limited company will not usually prevent the higher SDLT rates from applying on a new home purchase.
• If the old home is not genuinely disposed of as a previous only or main residence within the Schedule 4ZA rules, the replacement exception is unlikely to apply.
• A transfer of business property from a partnership to a company may in some cases produce little or no SDLT under Schedule 15, but only where the facts fit the statutory formula.
• If the property is owned by one individual but the company ownership is different, the position is more complex and cannot be treated as a straightforward mirror-image incorporation.

Practical Steps

To assess the SDLT position properly, a reader should work through the following points:

1. Identify exactly who owns the property now, both legally and beneficially.
2. For a home purchase, check whether the existing dwelling has been or will be disposed of in a way that satisfies paragraph 3 of Schedule 4ZA Finance Act 2003.
3. Do not assume that a transfer to a company counts as a disposal of a previous main residence for surcharge purposes.
4. If a business property is said to be partnership property, gather the partnership agreement, accounts, title documents, and evidence of capital ownership.
5. Map the ownership percentages before and after the proposed transfer.
6. Apply the Schedule 15 partnership rules carefully, including paragraphs 18 to 20 on the sum of the lower proportions.
7. If spouses or connected persons are involved, review whether that changes the relevant-owner analysis.
8. Obtain a current market valuation where SDLT may be charged by reference to market value or where anti-avoidance and connected-party issues may be relevant.

Conclusion

Moving a property into a company is not a simple workaround for SDLT. For a new home purchase, the higher rates usually remain in point unless the old main residence is actually replaced within the statutory rules. For partnership-to-company transfers, Schedule 15 can be helpful, but only where the ownership facts genuinely support the calculation. Small differences in ownership can make a large tax difference.
