While ISAs offer valuable tax benefits during your lifetime, it’s essential to understand how they’re handled after death, especially if you want to minimise complications for your beneficiaries. This post will cover what an ISA is, what happens to it upon the account holder’s death, the probate process, and the benefits and drawbacks involved.

What is an ISA?

An ISA, or Individual Savings Account, is a tax-efficient way to save or invest in the UK. Each tax year, adults in the UK can save up to a set annual limit in an ISA, currently £20,000.00 in the 2024/25 tax-year. There are several types of ISAs, including Cash ISAs, Stocks and Shares ISAs, Innovative Finance ISAs, and Lifetime ISAs, each serving different financial goals and preferences.

One of the major appeals of ISAs is their tax-free status, which allows for income or growth within the account without being subject to income tax or capital gains tax. However, this tax-free advantage applies only during the account holder’s lifetime. Upon death, there are specific rules and procedures that determine what happens to an ISA.

What Happens to an ISA When the Account Holder Dies?

When an ISA holder passes away, the tax advantages associated with the ISA cease. At the point of death, the ISA is ‘frozen’ as a tax-free wrapper, and it effectively becomes part of the deceased’s estate. Here’s how it works: 

1. Freezing the ISA Balance: The value of the ISA at the date of death is noted. From that point, any income or growth generated by the ISA becomes taxable as part of the estate.

2. Managing the ISA During Probate: The ISA remains frozen during probate, which is the legal process that validates the will (if there is one) and administers the deceased’s estate. During probate, any income, such as dividends or interest, generated by the ISA may be subject to income tax or capital gains tax at the estate’s tax rates.

3. Transfer to Beneficiaries: Once probate is granted, the executor (or administrator if there is no will) can access the ISA funds. These funds, now part of the deceased’s estate, can be distributed according to the instructions in the will or based on intestacy laws if no will exists. 

The Additional Permitted Subscription (APS) Allowance

The government introduced a policy allowing a spouse or civil partner to inherit the tax benefits of an ISA. Known as the Additional Permitted Subscription (APS) allowance, it allows the surviving spouse to add the value of the deceased’s ISA to their own ISA allowance. 

For example, if an ISA holder had £50,000.00 in their ISA at death, the surviving spouse can make an additional, one-off contribution of up to £50,000.00 into their own ISA, effectively inheriting the tax-free status on the deceased’s ISA balance. It’s worth noting that APS is separate from the annual ISA allowance, and the surviving spouse does not need to inherit the funds directly to benefit from the APS—they simply need to have been married or in a civil partnership at the time of death.

Key Benefits of the ISA Process on Death

1. Continuation of Tax-Free Growth for Spouse or Civil Partner: The APS allowance provides an opportunity for the surviving spouse to continue enjoying tax-free growth on the deceased partner’s ISA funds.

2. Simplicity in Estate Planning: ISAs are relatively straightforward financial products, and the APS allowance allows for a smooth transfer of tax benefits to a surviving spouse without the need for complex tax structures.

3. Peace of Mind for the Deceased’s Partner: Knowing that a spouse or civil partner can maintain the tax benefits associated with the ISA can offer peace of mind to couples planning their finances together.

Drawbacks and Considerations 

1. ISA Tax Benefits Cease at Death: The primary drawback is that the ISA tax-free wrapper stops upon death, which may impact any investment gains during the probate period.

2. Inheritance Tax (IHT) Implications: The value of an ISA is included in the estate, potentially increasing the estate’s inheritance tax liability. An ISA can add to the taxable value of the estate, especially for those with significant ISA balances.

3. APS Complexity for Surviving Partner: For a surviving spouse or civil partner, the APS process can be somewhat complex. Each ISA provider handles APS differently, and there are strict timelines, often requiring the APS to be used within a set period (usually within three years of death or within 180 days of the estate administration completing).

4. Potential Delays in Accessing ISA Funds: If the estate is large or complex, probate can take several months, delaying the distribution of ISA funds to beneficiaries. Furthermore, ISAs that hold investments such as shares, the ability to manage these or make changes during this process is likely unavailable 

Preparing for ISA Transfer on Death

If you hold a significant ISA balance, here are some steps that can help simplify matters for your beneficiaries:

Consider a Will: Ensure you have a will that reflects your wishes for your ISA and other assets. This can streamline the probate process and help reduce delays.

Discuss APS Options with Your Partner: If you have a spouse or civil partner, discuss the APS process so they are aware of this option and can plan for any necessary contributions within the time limits.

Consider Estate Planning to Mitigate IHT: If you are concerned about inheritance tax, an ISA can be part of a broader estate planning strategy to ensure tax-efficiency for your beneficiaries such as the use of AIM ISAs (however this is a complex area of finance and you should seek professional advice due to the additional risks of these types of investments)

Final Thoughts

Understanding what happens to your ISA on death is an essential part of estate planning. While the tax-free benefits of an ISA don’t continue indefinitely, options like the APS allowance mean a surviving spouse or civil partner can carry on benefiting from those advantages. By planning ahead and considering both the benefits and limitations of ISAs in estate planning, you can help ensure a smoother financial transition for your love
