Inheritance Tax Rules for Major Interests in Dwellings Explained

Inherited shares in dwellings and LTT higher rates

When deciding if the higher residential rates of Land Transaction Tax apply to a later property purchase, an inherited share in a dwelling is not always counted straight away. In general, an inherited interest of more than 50% counts from the date of inheritance, while an inherited interest of 50% or less is usually ignored for 3 years unless later changes mean it should count sooner.

• If you inherit more than 50% of a dwelling, it is usually treated as owned from the date you inherit it and may trigger the higher LTT rates on a later purchase.
• If you inherit 50% or less, that interest is usually ignored for higher-rates purposes for 3 years, after which it will normally start to count.
• Your share may be worked out by looking at your own interest together with that of your spouse or civil partner, and special rules can also apply to certain joint tenancy arrangements.
• The 3-year protection can end early if ownership changes, for example through a deed of variation, buying further shares in the dwelling, or marrying or entering into a civil partnership.
• The date of inheritance is usually the date the interest is actually acquired under a will or intestacy, not simply the date of death; a variation within 2 years of death can change that date.
• Interests held by minor children may sometimes be treated as owned by a parent, which can affect whether the higher rates apply.

Inherited interests in dwellings and the LTT higher rates

This page explains how an inherited share in a dwelling is treated when working out whether the higher rates of Land Transaction Tax apply to a later purchase. The key point is that an inherited interest is not always counted in the same way. A share of more than 50% is treated as owned straight away. A share of 50% or less is usually ignored for higher-rates purposes for 3 years, unless the position changes.

What this rule is about

The higher rates of LTT can apply when a person buys a dwelling and, at the effective time of that purchase, they already own a major interest in another dwelling. Inherited property can create difficulty here, because a person may receive a share in a dwelling without having chosen to buy it.

Paragraph 34 of Schedule 5 deals with that problem. It sets special rules for inherited interests in dwellings. The rule is designed to distinguish between:

• someone who inherits a substantial interest in a dwelling, and
• someone who inherits only a smaller share.

That distinction matters because it can affect whether a later purchase is taxed at the higher residential rates.

What the official source says

The official material says that if a taxpayer inherits an interest in a dwelling and that interest represents more than 50% of the value of the interest, it is treated as owned by the taxpayer from the date of inheritance.

A taxpayer is treated as owning a beneficial share of more than 50% if:

• the taxpayer alone is entitled to an interest greater than 50%,
• the taxpayer and their spouse or civil partner together own, as tenants in common, an interest greater than 50%, or
• the dwelling is owned by no more than 3 joint tenants, and 2 of those joint tenants are the taxpayer and their spouse or civil partner.

The source also says that interests owned by minor children are generally treated as owned by their parent, unless the child’s interest arises from an acquisition by a court-appointed deputy.

If the inherited interest is 50% or less, whether looked at individually or, where relevant, together with the spouse’s or civil partner’s interest, it is not treated immediately as an interest in another dwelling for higher-rates purposes. Instead, it is only treated as owned after 3 years from the date of inheritance.

However, that 3-year protection can end early. If, during those 3 years, the taxpayer’s interest in the dwelling changes because of:

• a variation of a disposition,
• the acquisition of other interests in the dwelling, or
• marriage or entering into a civil partnership,

and the result is that the interest becomes greater than 50%, it is then treated immediately as a major interest for the higher-rates rules.

The source defines the date of inheritance as the date on which the individual acquires the interest in or towards satisfaction of an entitlement under a will or intestacy.

There is also a special rule where there is a variation of a disposition within 2 years of death. In that case, the date of inheritance is taken to be the date of acquisition under the variation.

What this means in practice

The practical question is whether the inherited dwelling counts as “another dwelling” when the person later buys a home.

If the inherited share is more than 50%, the answer is generally yes from the date of inheritance. That inherited dwelling is then capable of triggering the higher rates on a later purchase, unless some other relieving rule applies, such as replacement of an only or main dwelling.

If the inherited share is 50% or less, the inherited dwelling is temporarily ignored for this purpose for 3 years. During that 3-year period, a later purchase may avoid the higher rates if the inherited interest is the only possible “other dwelling” interest.

But this is not a permanent exemption. Once the 3 years have passed, the inherited interest is treated as an interest in another dwelling for the higher-rates rules.

The position can also change before the 3 years are up. If the person’s share increases above 50%, or if marriage or civil partnership means interests are aggregated so that together they exceed 50%, the inherited dwelling may start counting immediately.

How to analyse it

A sensible way to analyse the rule is to ask these questions in order:

• Was the interest acquired by inheritance, meaning under a will or intestacy?
• What is the date of inheritance for this purpose?
• At that date, does the taxpayer alone own more than 50%?
• If not, do the taxpayer and spouse or civil partner together hold more than 50%?
• Is the property held by joint tenants in a way that brings the special spouse or civil partner rule into play?
• Are any minor children’s interests attributed to a parent under the deeming rule?
• If the inherited share was 50% or less, has 3 years passed since the date of inheritance?
• During that 3-year period, has the position changed because of a variation, a further acquisition of interests, or marriage/civil partnership?
• At the time of the later purchase, is the inherited dwelling now treated as another dwelling for higher-rates purposes?

It is important to focus on the position at the time of the later transaction, not just on what was inherited originally.

Example

Suppose two siblings inherit two dwellings in equal shares under their mother’s will. Each sibling receives a 50% interest in each dwelling. On those facts, neither sibling has inherited more than 50% of a dwelling. If neither owns any other dwelling interests, each may be able to buy a dwelling within the next 3 years without the higher rates applying, because the inherited interests are not yet counted.

Now suppose that, within that period, the will is varied so that one sibling takes one dwelling outright and the other sibling takes the other dwelling outright. From the date of that variation, each sibling is treated as owning more than 50% of a dwelling. From then on, a later purchase of another dwelling may fall within the higher rates, unless it qualifies as replacement of an only or main dwelling.

Why this can be difficult in practice

The main difficulty is that an inherited interest may not stay static. A person may begin with a share that is ignored for 3 years, but later events can change that result.

Particular care is needed where:

• the inherited property is held with a spouse or civil partner, because interests may need to be considered together,
• the ownership is split between tenants in common and joint tenants, because the source applies different tests,
• a deed of variation or other variation of disposition changes who is entitled to what,
• further interests in the same dwelling are acquired later, or
• marriage or civil partnership changes the way ownership is assessed.

Another point that can be overlooked is timing. The date of inheritance is not simply the date of death. The source says it is the date the individual acquires the interest in satisfaction of the will or intestacy. Where there is a qualifying variation within 2 years of death, the source applies a special timing rule. That timing can affect both the 3-year period and whether the higher rates apply to an intervening purchase.

The rule on minor children’s interests can also alter the analysis. If a child’s interest is treated as owned by a parent, that may affect whether the parent is treated as holding a major interest in another dwelling.

Key takeaways

• An inherited interest of more than 50% is generally counted immediately for LTT higher-rates purposes.
• An inherited interest of 50% or less is usually ignored for 3 years, but it can start counting earlier if the ownership position changes.
• Spouse or civil partner ownership, variations of disposition, later acquisitions, timing, and attribution of minor children’s interests can all change the result.
