Does owning a motorhome affect Stamp Duty Land Tax on a shared ownership purchase?

Introduction

People buying a shared ownership home often want to know whether anything else they own could affect the Stamp Duty Land Tax (SDLT) bill. A common question is whether a motorhome, caravan or similar holiday vehicle counts as another dwelling for SDLT purposes and increases the tax due.

The short answer is no. Owning a motorhome does not usually affect SDLT on the purchase of a residential property, including a shared ownership property, because a motorhome is not treated as land or a dwelling for these purposes.

The Question

A homeowner is selling their current home and buying a shared ownership property. Some SDLT will be payable on the purchase. They also own a motorhome used for holidays and want to know whether that motorhome could affect the SDLT position, including whether it might trigger any higher rates.

Nick’s Explanation

Nick’s answer was clear: a motorhome is exempt from SDLT. In other words, owning a motorhome does not count in the same way as owning another residential property.

He referred to HMRC’s SDLT manual, which explains that certain moveable property is outside the charge to SDLT. That is because SDLT applies to land transactions, not to ownership of vehicles such as motorhomes.

The Law

SDLT is charged under the Finance Act 2003 on land transactions. Broadly, the tax applies when a chargeable interest in land is acquired.

For most residential buyers, the key SDLT questions are:

• whether the transaction involves land in England or Northern Ireland;
• whether the property being bought is residential property;
• whether any reliefs apply, including special rules for shared ownership; and
• whether the higher rates for additional dwellings apply.

A motorhome does not normally fall within these rules because it is not a chargeable interest in land. It is a vehicle or chattel, not land or a building held as real property.

HMRC’s guidance at SDLTM10023 supports the distinction between land transactions and moveable property. SDLT is concerned with land, buildings and rights over land, not ordinary ownership of vehicles.

Analysis

The issue can be worked through in a few simple steps.

1. Identify what is being bought. In this scenario, the buyer is acquiring a shared ownership interest in a residential property. That is potentially within the SDLT rules.

2. Identify what else the buyer owns. The buyer also owns a motorhome used for holidays.

3. Ask whether the motorhome is land or a dwelling for SDLT purposes. It is not. A motorhome is moveable property, not an interest in land.

4. Consider whether it could count as an additional dwelling. Again, the answer is no. The higher rates for additional dwellings apply by reference to ownership of relevant dwellings and interests in dwellings. A motorhome does not usually fall into that category.

5. Apply the shared ownership rules separately. The SDLT treatment of the shared ownership purchase will depend on the structure of that transaction, including whether a market value election is made and what premium or rent is payable. The existence of a motorhome does not alter that analysis.

So, if the only concern is ownership of a motorhome, that should not increase the SDLT bill on the shared ownership purchase.

Outcome

Owning a motorhome used for holidays does not usually affect SDLT on a shared ownership purchase. It does not count as another dwelling for SDLT purposes and should not by itself trigger the higher rates for additional dwellings.

The SDLT due will instead depend on the normal shared ownership SDLT rules and the details of the property transaction itself.

Practical Steps

To assess the SDLT position properly, a buyer should:

• confirm the price, premium and lease terms of the shared ownership purchase;
• check whether a market value election is being made;
• review whether they own any other actual dwellings or interests in dwellings, not just vehicles or holiday equipment;
• consider whether they are replacing their only or main residence, if the higher rates are in point; and
• ask their conveyancer or SDLT adviser to calculate the tax based on the shared ownership documentation.

If the only additional asset is a motorhome, that asset should not affect the SDLT calculation.

Conclusion

A motorhome is not usually relevant to SDLT on a home purchase. For a shared ownership buyer, the important SDLT issues are the structure of the shared ownership transaction and whether any other residential properties are owned. A motorhome on its own should not increase the tax.
