Inheritance Tax for Unmarried Couples

Inheritance tax is a significant financial consideration in estate planning. While the rules are designed to allow spouses and civil partners substantial reliefs, unmarried couples in the UK do not enjoy the same advantages. This disparity can lead to unexpected tax burdens, forcing the surviving partner to make difficult financial decisions. Understanding these rules and taking proactive steps is essential for unmarried couples to protect their estates and provide for each other.

What Is Inheritance Tax?

Inheritance tax is a levy on the estate of a person who has died. The tax is calculated based on the total value of the deceased’s estate, including:

  • Cash in the bank
  • Investments
  • Property or business holdings
  • Vehicles
  • Payouts from life insurance policies (if not written in trust)

From this total, any debts and liabilities (e.g., mortgages, loans) are deducted to determine the taxable estate value.

In the UK, the current inheritance tax threshold (nil rate band) is £325,000. Estates valued below this amount are exempt from Inheritance Tax. For those exceeding this threshold, a standard tax rate of 40% applies to the portion above £325,000.

Key Differences Between Married Couples and Unmarried Couples

The inheritance tax rules offer significant benefits to married couples and civil partners, which are not available to unmarried partners, regardless of the length or depth of their relationship. Below are the key differences:

Spousal Exemption

Assets passed to a spouse or civil partner are entirely exempt from Inheritance Tax, provided the recipient resides in the UK. Unmarried partners do not qualify for this exemption, meaning any inheritance they receive is subject to Inheritance Tax if the estate exceeds the nil rate band.

Transferable Allowances

Married couples and civil partners can transfer unused portions of their nil rate band to the surviving partner upon the first death. This effectively doubles the threshold for the surviving partner, allowing up to £1 million to pass tax-free if the residential nil rate band is also utilised. Unmarried couples cannot transfer unused allowances, resulting in higher tax liabilities.

Residential Nil Rate Band

An additional allowance of up to £175,000 is available when the deceased’s main residence is passed to direct descendants (e.g., children, stepchildren, or grandchildren). Unused portions of this allowance can also be transferred between spouses or civil partners but not between unmarried partners.

Joint Ownership of Property

For unmarried couples, property ownership plays a crucial role in determining inheritance tax liabilities. The way property is owned—either as joint tenants or tenants in common—affects how the property is passed on and whether Inheritance Tax is applicable.

  1. Joint Tenants:
    • Both partners own the entire property jointly.
    • Upon the death of one partner, their share automatically passes to the surviving partner under the right of survivorship. However, this transfer is not exempt from Inheritance Tax for unmarried couples if the value exceeds the threshold.
  2. Tenants in Common:
    • Each partner owns a defined share of the property, which can be unequal.
    • The deceased’s share passes according to their will (or intestacy rules if there is no will). This share may be subject to Inheritance Tax, depending on its value.

Intestacy Rules: A Challenge for Unmarried Couples

If a person dies without a will (intestate), the intestacy rules determine how their estate is distributed. These rules do not recognise unmarried partners, regardless of how long they have been together. Instead, the estate is distributed to the deceased’s legal relatives, such as children, parents, or siblings.

This means that without a will:

  • An unmarried surviving partner has no automatic right to inherit any portion of the estate.
  • Family members who inherit may choose to share their inheritance with the surviving partner, but they are not legally obligated to do so.

How Inheritance Tax Affects Unmarried Couples

Unmarried couples often face significant challenges when it comes to Inheritance Tax, including:

  • Higher Tax Liabilities: Without spousal exemptions, the estate left to the surviving partner is subject to Inheritance Tax if it exceeds the nil rate band.
  • Loss of Unused Allowances: Unmarried partners cannot transfer unused nil rate bands or residential nil rate bands, which increases the likelihood of tax liability.
  • Risk of Asset Liquidation: The surviving partner may need to sell assets, such as the family home, to cover Inheritance Tax liabilities.
  • Jointly Owned Assets: Even jointly owned assets can be subject to Inheritance Tax if the deceased’s share exceeds the threshold.

Strategies to Minimise Inheritance Tax for Unmarried Couples

While the tax rules for unmarried couples are less favourable, there are several strategies to minimise Inheritance Tax liabilities:

Write a Valid Will

A will ensures that assets are distributed according to your wishes and can provide financial security for your partner. Without a will, the intestacy rules apply, leaving the surviving partner without legal rights to the estate.

Consider Joint Ownership Structures

Owning property as joint tenants allows the surviving partner to inherit the property automatically, although Inheritance Tax may still apply. Tenants in common arrangements can offer flexibility in how shares are passed on but require careful planning to mitigate Inheritance Tax.

Use Lifetime Gifting

Gifts made during a person’s lifetime may reduce the value of the taxable estate, provided the donor survives for seven years after making the gift.

Life Insurance Policies

Placing life insurance policies in trust ensures that the payout is excluded from the taxable estate, providing funds to cover Inheritance Tax liabilities.

Seek Professional Advice

A solicitor or financial planner can help design an estate plan that minimises Inheritance Tax while ensuring the surviving partner’s financial security.

Case Study: The Impact of Inheritance Tax on Unmarried Couples

Scenario:

  • Anna and Mark have been cohabiting for 15 years but are not married.
  • They jointly own a property worth £600,000 as tenants in common, with each owning a 50% share.
  • Anna passes away without a will, and her share of the property (worth £300,000) becomes part of her taxable estate.

Outcome:

  • Anna’s estate exceeds the £325,000 nil rate band, resulting in Inheritance Tax on the excess.
  • Mark, as the surviving partner, does not benefit from spousal exemptions and must pay 40% Inheritance Tax on the £75,000 excess (£30,000).
  • Mark may need to sell the property or take out a loan to cover the tax liability.

The Importance of Planning

Unmarried couples must take proactive steps to protect their estates and minimise tax liabilities. Key actions include:

  • Drafting Comprehensive Wills: Ensure that assets are distributed to the surviving partner and not left to chance under intestacy rules.
  • Understanding Ownership Structures: Review how property and assets are owned to identify potential tax implications.
  • Regularly Reviewing Estate Plans: Circumstances change, so regular reviews ensure that estate plans remain aligned with your wishes and legal requirements.
  • Utilising Exemptions and Reliefs: Explore options such as lifetime gifting and trusts to reduce the taxable estate.

Conclusion

Inheritance tax rules in the UK place unmarried couples at a disadvantage compared to married couples and civil partners. Without the benefits of spousal exemptions and transferable allowances, unmarried couples face higher tax liabilities, potential asset liquidation, and financial insecurity for the surviving partner. However, with careful planning, these challenges can be mitigated.

Drafting a valid will, understanding joint ownership structures, and seeking professional advice are critical steps for unmarried couples to protect their assets and ensure financial stability for their partner. By taking proactive measures, you can navigate the complexities of inheritance tax and provide peace of mind for the future.
