Joint Tenancy vs Tenants in Common and IHT in the UK

In England and Wales, when two or more people buy a property together, they typically choose between:

• Joint Tenants
• Tenants in Common

Each type gives different rights and responsibilities which become particularly important when one owner dies or if the relationship between the owners changes.

What Is Joint Tenancy?

With joint tenancy, both owners have equal ownership of the whole property. If one person dies, the property automatically passes to the surviving owner. This is called the right of survivorship.

Key Features:

• Equal ownership share
• Property automatically passes to the other owner on death
• Cannot leave your share of the property to someone else in your will
• Often used by married couples or civil partners

Important: If your will says you want to leave the property to someone else, it won’t override a joint tenancy agreement.

What Is Tenancy in Common?

With tenancy in common, each owner holds a specific share of the property. The shares don’t have to be equal. When one person dies, their share passes to whoever they name in their will, not the other owner.

Key Features:

• Ownership can be split unequally (e.g., 70/30)
• No automatic transfer on death
• You can leave your share to anyone in your will
• Suitable for people who want to protect their share for children or other beneficiaries

Tenants in Common vs Joint Tenants – Key Differences

How Much is Inheritance Tax in the UK?

The current rate of Inheritance Tax is 40%. It is levied on the portion of the estate that exceeds the available tax-free thresholds. However, if the estate qualifies for a reduced rate because at least 10% of the net value of the estate is left to charity, the rate can be reduced to 36%.

As of the current tax year (2025-2026), the standard nil-rate band (amount exempt from IHT) is £325,000. In addition to the standard nil-rate band, there is also the residence nil-rate band.

This applies when a person leaves their home to their direct descendants (children, grandchildren, etc.). The current residence nil-rate band is £175,000. This can be added to the standard nil-rate band, increasing the total tax-free threshold to £500,000 for eligible estates.

How These Ownership Structures Affect UK Inheritance Tax (IHT)

The way a property is owned significantly impacts how it’s treated for IHT purposes in the UK:

1. Joint Tenancy and IHT:

• Deemed Part of the Deceased’s Estate: When a joint tenant dies, the value of their share of the property is included in their estate for IHT purposes.
• Passing by Survivorship: Although the property passes directly to the surviving joint tenant(s) by operation of law (outside of the will), it is still deemed to have been part of the deceased’s taxable estate.
• Spousal Exemption: If the surviving joint tenant is the deceased’s spouse or civil partner, the value of the deceased’s share passing to them is usually exempt from IHT under the spouse/civil partner exemption.
• Taxable to Other Joint Tenants: If the surviving joint tenant is not the deceased’s spouse or civil partner, the value of the deceased’s share is still taxable in their estate, even though it passes to the survivor. The survivor then owns the entire property.

2. Tenancy in Common and IHT:

• Deceased’s Share Forms Part of the Estate: When a tenant in common dies, only their specific share of the property forms part of their estate for IHT purposes.
• Distributed According to Will or Intestacy: This share is then distributed according to the deceased’s will or the rules of intestacy, just like any other asset in their estate.
• No Automatic Transfer: There is no automatic transfer to the surviving co-tenant(s). The deceased’s share could pass to their children, other relatives, or anyone named in their will.
• Planning Opportunities: Tenancy in common can offer more flexibility for IHT planning, as individuals can direct their specific share to beneficiaries other than the surviving co-owner. This can be useful in situations like:
  • Second marriages: Allowing individuals to ensure their children from a previous relationship inherit their share of the property.
  • Tax mitigation: With careful planning, it might be possible to utilize the deceased’s nil-rate band (the threshold below which IHT is not usually payable) against their share of the property.

Key Differences for IHT Planning:

• Control over Inheritance: Tenancy in common allows individuals to control who inherits their share of the property, unlike joint tenancy where it automatically goes to the survivor.
• Utilizing Tax Allowances: Tenancy in common provides more scope for utilizing each individual’s tax allowances (like the nil-rate band) against their share of the property.
• Potential for Double Taxation: With joint tenancy (when not spouse/civil partner), the deceased’s share is taxed in their estate, and the survivor ends up owning the whole property, which could then be subject to IHT again on their death. Tenancy in common can help mitigate this risk.

Important Considerations:

• Legal Documentation: The legal documents (e.g., the title deeds) will specify whether a property is held as joint tenants or tenants in common.
• Severance of Joint Tenancy: It’s possible to sever a joint tenancy, converting it into a tenancy in common, which can be a key step in IHT planning.
• Professional Advice: IHT planning involving property ownership is complex. It’s crucial to seek advice from a qualified legal and tax professional in the UK to understand the implications for your specific circumstances and to ensure any planning is effective and compliant with the law.

In summary, while joint tenancy offers simplicity in the automatic transfer of property on death, tenancy in common provides greater flexibility for estate planning and IHT mitigation, allowing individuals to direct their share of the property according to their wishes and potentially utilize tax allowances more effectively.
