Do you pay Stamp Duty Land Tax on a £125,000 home purchase if it will be your main residence?

Introduction

People often assume that no Stamp Duty Land Tax (SDLT) is due if the purchase price is low. In many cases that is right, but the answer can change if the buyer already owns another dwelling and the higher rates for additional dwellings apply. The key question is not just the price. It is also whether the property is being bought as the buyer’s only or main residence, or as an additional property.

The Question

A buyer planned to purchase a residential property for £125,000. The property was intended to become the buyer’s home after the buyer sold their existing house. The buyer initially thought no SDLT would be payable because of the price. The issue was whether that was correct, and whether the higher rates for additional dwellings might apply instead.

Nick’s Explanation

Nick’s key point was that the purchase price alone does not always settle the SDLT position. He asked whether the property was being bought as an additional property or as the buyer’s main home.

In anonymised form, his reasoning was:

“If the property is bought as an additional dwelling, the higher rates may apply. If it is bought as the buyer’s main residence, the position is different.”

That is the correct starting point. A £125,000 purchase may carry no SDLT at standard residential rates, but if the higher rates for additional dwellings apply, SDLT can still be payable even at that price level.

The Law

SDLT on land transactions in England is charged under the Finance Act 2003.

For residential property, the amount of SDLT depends on:

• whether the property is residential, mixed, or non-residential;
• the effective date of the transaction;
• the chargeable consideration; and
• whether any special charging rules apply, including the higher rates for additional dwellings.

The higher rates for additional dwellings are contained in Schedule 4ZA to the Finance Act 2003. Broadly, they can apply where, at the end of the day of purchase, the buyer owns more than one dwelling and is not replacing their only or main residence.

Where the higher rates apply, SDLT is charged at a surcharge above the standard residential rates. That means a transaction which would otherwise produce no SDLT at ordinary rates can still give rise to SDLT if it falls within Schedule 4ZA.

Whether a purchase counts as a replacement of only or main residence depends on the statutory conditions. In broad terms, the buyer usually needs to dispose of a previous only or main residence and acquire a new one. Timing matters. If the old home has not yet been sold by completion, the buyer may have to pay the higher rates first and then claim a refund later if the statutory conditions are met.

Analysis

Step 1: Start with the price.

On a straightforward residential purchase for £125,000, standard residential SDLT may be nil, depending on the rates in force on the effective date. That is why buyers often think there is nothing further to consider.

Step 2: Ask whether the buyer already owns another dwelling.

If, on completion of the new purchase, the buyer still owns their existing home, the buyer may own two dwellings at the end of that day. That raises the Schedule 4ZA question.

Step 3: Ask whether the new purchase is a replacement of the buyer’s only or main residence.

If the buyer has already sold their previous main home and is buying the new property to live in, the higher rates will usually not apply, provided the statutory conditions are met.

If the buyer has not yet sold the previous main home by the completion date, the higher rates may apply initially because the buyer still owns the old dwelling at the end of the day. In that situation, the buyer may later be able to reclaim the surcharge if the previous main residence is sold within the permitted period and the other conditions are satisfied.

Step 4: Apply that to this type of scenario.

Here, the buyer intended to move into the newly purchased property as their home and was trying to sell their existing house. That points toward a main residence purchase rather than the acquisition of a long-term additional property. However, the precise SDLT result depends on the timing:

• if the old home is sold before or on the same day as completion of the new purchase, the higher rates should usually not apply;
• if the old home is still owned at the end of the completion day, the higher rates may apply at that point, even though the buyer intends to move.

Step 5: Consider the practical tax effect at £125,000.

If the higher rates do not apply, the SDLT may be nil.

If the higher rates do apply, SDLT may still be payable despite the modest price, because the surcharge changes the calculation. So the statement “there is no stamp duty because the price is £125,000” is only safely correct if the purchase is not caught by the additional dwelling rules.

Outcome

A buyer purchasing a home for £125,000 may have no SDLT to pay at standard residential rates. But that is not the end of the analysis. If the buyer still owns another dwelling at completion and is not treated as replacing their only or main residence at that time, the higher rates for additional dwellings may apply and SDLT may become payable.

So the practical conclusion is simple: a £125,000 price does not automatically mean no SDLT. The buyer must also check whether Schedule 4ZA applies on the completion date.

Practical Steps

• Confirm the purchase price and the completion date.
• Check whether the property is residential for SDLT purposes.
• List all dwellings the buyer will own at the end of the completion day, including any existing home.
• Decide whether the new property is intended to be the buyer’s only or main residence.
• Check whether the previous only or main residence has already been sold, or will be sold on the same day.
• If the old home will be sold later, consider whether the higher rates must be paid first and whether a refund claim may later be available.
• Keep evidence showing which property was the buyer’s main residence and when any disposal took place.

Conclusion

The correct SDLT answer depends on more than the purchase price. A £125,000 home purchase may attract no SDLT at standard rates, but if the buyer still owns another dwelling at completion, the higher rates for additional dwellings may apply. The key question is whether the purchase is, in law, a replacement of the buyer’s only or main residence.
