Transferring Buy-to-Let Properties to a Company Without SDLT
NO VAT
Can you transfer rental properties into your limited company without SDLT?
Introduction
Many landlords ask whether they can move personally owned rental properties into a limited company without paying Stamp Duty Land Tax (SDLT). This usually comes up where the properties have been held for years as buy-to-lets or HMOs and the owner is now considering incorporation for tax, finance or long-term planning reasons.
The SDLT position is often misunderstood. A transfer to your own company is not ignored for SDLT. In most cases it is treated as a chargeable land transaction, and where the company is connected to the owner, SDLT is usually calculated by reference to market value rather than the price actually paid. A possible exception can arise where the properties are genuinely held in a partnership business and the partnership incorporation rules in Schedule 15 to the Finance Act 2003 apply.
The Question
A landlord owns three residential investment properties acquired many years ago. Two are owned solely by the landlord. One is jointly owned with a family member who was added for mortgage affordability reasons but has not taken part in managing the lettings business. The properties are a mix of buy-to-lets and HMOs. The landlord wants to transfer them into a limited company and wants to know whether this can be done without triggering SDLT, particularly in light of the rules on partnership incorporations.
Nick’s Explanation
Nick’s explanation was that the starting point is the connected company market value rule. In anonymised form, his reasoning was:
“Transferring property into a company you control is a land transaction for SDLT purposes. Where the company is connected to you, section 53 of the Finance Act 2003 applies so that SDLT is charged by reference to market value.”
He also explained that there can sometimes be relief under Schedule 15 where a genuine partnership business transfers property to a company owned by the same persons in the same proportions. In that situation, the market value element can in some cases be reduced to nil under the Schedule 15 formula.
However, he then applied the facts more closely and concluded that this relief was unlikely to be available here. The reason was that the jointly named family member had no real involvement in the business and had only been included for borrowing purposes. On those facts, there did not appear to be a genuine partnership carrying on the property business.
Nick further clarified an important point about mortgages. In this type of connected company transfer, where section 53 applies, SDLT is charged on market value. The mortgage is not then added on top of that market value figure. The tax charge is based on the market value of the property transferred.
His practical conclusion was that, on these facts, the transfer would be treated as a normal transfer to a connected company at full market value, with SDLT payable at the residential rates applicable at the time, including the higher rates for additional dwellings if those rates are engaged.
The Law
The main SDLT provisions are these:
- Finance Act 2003, section 42: SDLT is charged on land transactions.
- Finance Act 2003, section 53: where the purchaser is a company connected with the vendor, the chargeable consideration is deemed to be at least the market value of the property.
- Finance Act 2003, Schedule 15, Part 3: special rules for transfers of partnership property, including incorporation cases.
- Finance Act 2003, Schedule 15, paragraph 10: provides the market value formula for certain transfers from a partnership.
- Finance Act 2003, Schedule 4, paragraph 8(1): assumption of debt can be chargeable consideration.
- Finance Act 2003, Schedule 15, paragraph 17: applies debt rules in the partnership context.
In broad terms, if an individual transfers a property to a company they control, section 53 usually means SDLT is calculated on the market value of the property at the effective date of the transaction. This applies even if the company pays little or nothing.
The main route by which the market value charge may be reduced is the partnership code in Schedule 15. Under paragraph 10, the chargeable consideration can be reduced by reference to the “sum of the lower proportions” or “SLP”. If the same partners own the company in the same proportions as their partnership interests, the formula can reduce the market value element to nil.
But that only helps if there is a real partnership in the first place. A partnership is judged by substance, not labels. Relevant indicators can include shared profits, joint decision-making, partnership accounts, partnership tax returns, and evidence that the business was actually carried on together.
It is also important not to confuse SDLT rules with the separate question of whether a dwelling is suitable for use as a dwelling. In uninhabitable or not suitable for use cases, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. That line of authority is relevant to property condition arguments, but it does not create a route around the connected company market value rule for incorporation cases.
Analysis
Step 1: Is there a land transaction?
Yes. Moving a property from personal ownership into a limited company is a transfer of a chargeable interest in land. That is within the SDLT regime.
Step 2: Is the company connected with the transferor?
Usually yes, where the landlord is transferring the properties into their own company. That triggers section 53.
Step 3: What does section 53 do?
It substitutes market value as the chargeable consideration. So even if the company issues shares, takes over liabilities, or pays no cash, the starting SDLT figure is the property’s market value.
Step 4: Can Schedule 15 reduce the SDLT charge?
Only if the properties are partnership assets of a genuine partnership business and the statutory conditions are met. This is the point often associated with property incorporation planning.
Step 5: Was there a genuine partnership here?
On the facts given, probably not. Two properties were owned by one individual alone. The third was jointly owned with a family member who was not involved in management and was included only for affordability. That does not naturally point to a business carried on in partnership.
Joint legal ownership by itself is not enough. Nor is being on the mortgage. For Schedule 15 purposes, HMRC and the courts look at the real commercial position. Was there a shared business? Were profits shared? Were decisions taken jointly? Was the business held out as a partnership? Were there partnership accounts or tax returns? If the answer is no, the partnership route is weak.
Step 6: What about the mortgage?
In a straightforward connected company transfer governed by section 53, SDLT is charged on market value. The mortgage is not added on top of market value as a second layer of consideration. The market value rule already sets the taxable amount.
In a true Schedule 15 partnership case, debt can still matter because paragraph 17 brings in debt assumptions as chargeable consideration. But that only becomes relevant if there is a genuine partnership case to begin with.
Step 7: Do higher residential rates apply?
Usually, a company acquiring residential property is within the higher rates regime unless a specific exclusion applies. So if the transfer proceeds and no relief is available, SDLT is likely to be charged at the higher residential rates on the market value.
Outcome
On these facts, the practical answer is that a transfer of the rental properties into the landlord’s own limited company is unlikely to be free of SDLT.
The most likely result is:
- section 53 Finance Act 2003 applies because the company is connected;
- SDLT is calculated on the full market value of each property transferred;
- Schedule 15 partnership relief is unlikely to apply because the facts do not show a genuine partnership business;
- the higher residential SDLT rates are likely to apply to the company acquisition.
Practical Steps
If you are assessing a possible incorporation, gather evidence in this order:
- Confirm the legal ownership of each property from the title register and purchase documents.
- Check whether there is any real evidence of a partnership business, such as:
- partnership tax returns,
- partnership accounts,
- a partnership agreement,
- shared rental income records,
- shared expense records,
- evidence of joint business decisions and management.
- Obtain current market valuations for each property.
- Check current mortgage balances and whether the lender would consent to any transfer.
- Model the SDLT cost on market value, including higher residential rates where relevant.
- Consider the wider tax position as well, including possible capital gains tax and any income tax or corporation tax consequences of incorporation.
- Have the SDLT position reviewed on the actual documents before any transfer is carried out.
If the only basis for saying there was a partnership is that another person was named on one title or mortgage for affordability reasons, that is usually not enough on its own to support Schedule 15 treatment.
Conclusion
Transferring personally owned rental properties into your own limited company will usually trigger SDLT on market value under section 53 Finance Act 2003. The main exception is where there is a genuine partnership business and the Schedule 15 incorporation rules apply. Where one co-owner was included only for borrowing purposes and did not participate in the business, that exception is unlikely to be available.
