LBTT Part Exchange Relief Guide for House Building Company Transactions

LBTT relief for housebuilder part-exchange purchases

This relief applies in Scotland where a housebuilder takes a buyer’s existing home in part exchange for a new-build home sold by that same housebuilder. If the legal conditions are met, the housebuilder’s purchase of the old home can be fully or partly relieved from LBTT, but the buyer’s purchase of the new home is still taxed under the usual rules.

• The relief is limited to genuine part-exchange deals with a housebuilding company and does not apply to ordinary home swaps between private individuals.
• The buyer must be purchasing a new home from the housebuilder, and the old home must be given as all or part of the payment for that new home.
• The buyer must have lived in the old home as their main or only residence at some point in the two years before the housebuilder buys it.
• The buyer must intend to live in the new home as their main or only residence, so the relief is aimed at home moves rather than investment purchases.
• Full relief usually requires the old home’s garden or grounds to be within the permitted area, normally 0.5 hectares including the house site, although a larger area may qualify if appropriate to the property.
• If the land exceeds the permitted area, partial relief may still be available based on the market value of the permitted area, and claims are made through the LBTT return under the residential property relief option.

LBTT part exchange relief when a housebuilder takes your old home

This page explains a specific LBTT relief for part-exchange deals with housebuilders. It applies where a housebuilding company buys a person’s existing home as part of that person’s purchase of a new home from the same company. If the statutory conditions are met, the housebuilder’s purchase of the old home can be relieved from LBTT, or partly relieved if the land is too large.

What this rule is about

The relief is aimed at a common new-build arrangement. A buyer wants to move into a newly built home, but still owns their current home. To help the sale proceed, the housebuilder agrees to buy the buyer’s existing home and give credit for it against the price of the new home. That is the type of transaction this relief addresses.

The relief is not a general exemption for all property swaps. The official material makes clear that it does not apply simply because two people exchange homes. It is limited to a transaction involving a housebuilding company and a buyer acquiring a new home from that company.

What the official source says

Under schedule 4 to the Land and Buildings Transaction Tax (Scotland) Act 2013, a housebuilding company’s acquisition of a person’s home is relieved from LBTT if the required conditions are met.

The conditions include all of the following:

• The person must buy a new home from the housebuilding company.
• The person must have lived in the old home as their main or only residence at some point in the two years before the housebuilder bought it.
• The person must intend to live in the new home as their main or only residence.
• The old home must be sold to the housebuilding company in whole or in part consideration for the new home.

There is also a land-size condition. The garden or grounds sold with the old home must not exceed the permitted area. The permitted area is normally 0.5 hectares including the site of the house. A larger area can still count if it is appropriate to the size and character of the property. If so, the permitted area is the part of the land that would be most suitable for the occupation and enjoyment of the house as its garden or grounds if the rest were occupied separately.

If all the other conditions are met but the garden or grounds condition is not, partial relief may be available. In that case, the chargeable consideration for the housebuilder’s acquisition is worked out by deducting the market value of the permitted area from the market value of the home.

What this means in practice

The practical effect is that the relief benefits the housebuilder’s purchase of the old home, not the buyer’s purchase of the new home. The buyer still needs to consider the LBTT position on the purchase of the new home under the normal rules.

For the relief to apply, the old property must genuinely be the person’s home in the relevant sense. It is not enough that they own it. The source requires that they lived there as their main or only residence at some point during the two years before the housebuilder bought it.

The buyer must also be moving into the new property as their intended main or only residence. That means the relief is aimed at residential moves, not investment acquisitions.

The requirement that the old home is given in total or partial consideration matters because the old property must form part of the bargain for the new one. In other words, the transaction must be a true part-exchange arrangement with the housebuilder, not just a separate sale happening around the same time.

The land-size rule can be important where the old home comes with substantial grounds. If the grounds are within the permitted area, full relief may be available. If they are too extensive, the relief may be restricted rather than lost entirely.

How to analyse it

A sensible way to assess the relief is to work through these questions in order:

• Is there a housebuilding company involved?
• Is the person buying a new home from that company?
• Is the company buying that person’s existing home as part of the same overall deal?
• Did the person live in the old home as their main or only residence at some time in the two years before the company bought it?
• Does the person intend to occupy the new home as their main or only residence?
• Is the old home being transferred in total or partial consideration for the new home?
• What land is included with the old home, and does it fall within the permitted area?
• If the permitted area is exceeded, what is the market value of the permitted area for the purpose of calculating partial relief?

In practice, the residence conditions usually turn on evidence of occupation and intention. The permitted area issue usually turns on the physical extent and character of the land sold with the property.

The official guidance also indicates how the relief is claimed in the LBTT return: it falls under the “Relief for certain acquisitions of residential property” option in the “Type of Relief” drop-down.

Example

Illustration: A buyer agrees to purchase a newly built house from a developer. The developer also agrees to take the buyer’s current home in part exchange, with the agreed value of the old home being credited against the price of the new one. The buyer lived in the old home as their main residence within the previous two years and plans to live in the new-build as their main residence. If the old home is sold with no more than the permitted area of garden or grounds, the developer’s purchase of the old home can qualify for full relief.

If the same old home includes land beyond the permitted area, the relief may still apply in part. The taxable amount for the developer’s purchase is then adjusted by reference to the market value of the permitted area, rather than giving full relief for the whole acquisition.

Why this can be difficult in practice

The rule is narrow, but some of its conditions are fact-sensitive.

First, whether a property was the person’s “main or only residence” can be straightforward in many cases, but not always. A person may have more than one home, may have moved out before the transaction, or may have used the property in mixed ways. The source does not set out a detailed test, so the answer depends on the facts.

Second, intention to live in the new home as a main or only residence is also a factual matter. Usually this will be clear from the nature of the move, but intention can become less certain if plans change or the buyer has multiple properties.

Third, the permitted area rule can be difficult where a property has large gardens, paddocks, or other adjoining land. The legislation allows more than 0.5 hectares if a larger area is appropriate to the size and character of the house, but that is a judgement rather than a fixed formula.

Fourth, partial relief depends on market value calculations. Where only part of the land falls within the permitted area, valuation issues may arise, especially if the property is unusual or the land has development or amenity value.

Finally, this relief does not cover ordinary home swaps between private individuals. That is a common misunderstanding. The transaction must fit the statutory model of a housebuilder taking the old home as part of a purchase of a new home from that builder.

Key takeaways

• This relief applies to a housebuilder’s purchase of a buyer’s old home in a genuine part-exchange deal for a new home.
• The old home must have been lived in as the person’s main or only residence within the previous two years, and the new home must be intended as their main or only residence.
• If the old home includes too much land, full relief may not be available, but partial relief may still apply.
