Can a spouse inherit an ISA allowance when their husband, wife or civil partner dies? In most cases, the answer is yes, but the surviving spouse receives an additional ISA subscription allowance rather than simply taking ownership of the original ISA. This guide explains how the Additional Permitted Subscription works, what happens to the deceased person’s ISA during estate administration, and how inheritance tax and other tax issues may affect the estate. It also covers common mistakes, paperwork and questions to raise with the ISA provider or a qualified adviser.
What happens to an ISA after death
An ISA does not normally pass to a spouse as an ordinary tax-free account that can simply be carried on in the survivor’s name. The investments or cash inside it become part of the deceased person’s estate, although the account usually keeps its ISA tax advantages for a limited period while the estate is being dealt with. The provider will need evidence of the death and instructions from the personal representatives before it can release or transfer the assets.
For deaths from the relevant modern tax regime onwards, the ISA generally becomes a continuing account of the deceased. This means interest, dividends and investment growth can remain sheltered from UK income tax and capital gains tax during the permitted administration period. The continuing status ends when the account is closed, the estate administration is completed or the statutory time limit is reached, whichever applies first under the current rules. The executor or administrator should ask the provider to confirm the exact end date rather than assuming that the account remains protected indefinitely.
The person inheriting the underlying cash or investments is not necessarily the person entitled to the special ISA allowance. The allowance is normally available to a surviving spouse or civil partner, even if the will leaves the ISA assets to somebody else. Conversely, an unmarried partner, child or other beneficiary does not usually receive an Additional Permitted Subscription merely because they inherit the ISA itself.
How a spouse can use the extra allowance
A surviving spouse or civil partner may receive an Additional Permitted Subscription, commonly called an APS allowance. This is a separate allowance that can be used to subscribe to an ISA in the survivor’s own name, on top of their normal annual ISA allowance. It is not usually necessary for the survivor to inherit the money or investments held in the deceased person’s ISA, although the practical funding arrangements will need to be agreed with the executors and provider.
The size of the APS allowance is determined under rules that take account of the deceased person’s ISA holdings and, in some circumstances, subscriptions made during the tax year of death. The calculation can therefore differ from the amount that ultimately passes through the estate. Providers may ask for a valuation at the date of death, details of the deceased’s ISA subscriptions and evidence of the relationship. Exact rules and deadlines can change, so the survivor should obtain the current calculation from the provider or check the relevant GOV.UK guidance.
There are generally two routes. The surviving spouse can use the APS with the same ISA manager, which may be administratively simpler, or choose another ISA provider that accepts APS subscriptions. The survivor normally does not have to put the inherited assets into the new ISA; they can use other available money, subject to the provider’s process and the relevant deadline. A useful question to ask a regulated provider or qualified tax adviser is: What is the APS allowance, when does the subscription window end, and what evidence will you require?
A worked example of the allowance
Imagine that Priya’s civil partner dies holding a stocks and shares ISA valued at an illustrative £48,000 on the date of death. The estate leaves those investments to Priya, but the investments are sold during administration and the proceeds are eventually distributed. Priya may still be entitled to an APS allowance based on the statutory calculation, even though the original ISA has been closed and the assets were not transferred directly into a new ISA.
Suppose, purely as an illustration, that the provider confirms Priya’s APS allowance is £48,000. Priya could then subscribe up to that separate amount to an eligible ISA, in addition to any ordinary ISA subscriptions she makes under the annual allowance for that tax year. If she places £20,000 into an APS ISA first, the unused balance would usually be £28,000, subject to the provider’s rules and the time limit. The example is not a prediction of the allowance in any real estate; the provider must calculate it from the deceased person’s records and the legislation in force.
A second complication can arise where the ISA value changes between death and subscription. The APS figure is generally linked to the relevant statutory valuation rather than whatever amount the survivor later receives. This means a fall in investments, fees, withdrawals or a distribution from the estate does not automatically reduce or increase the allowance in the same way. The common mistake is to wait until the estate is fully distributed before making enquiries, only to discover that important provider forms or the APS deadline have been overlooked.
Inheritance tax and other tax questions
The value of an ISA is usually included in the deceased person’s estate for inheritance tax purposes. The ISA wrapper protects qualifying income and gains from personal tax while it remains in force, but it does not normally make the underlying assets disappear from the inheritance tax calculation. Transfers to a spouse or civil partner will often qualify for the spouse exemption, but the result depends on the estate, the beneficiary’s status, domicile considerations and any available allowances.
People often ask, can beneficiaries pay the estate's inheritance tax? In practice, the personal representatives are responsible for dealing with the estate’s tax and debts, using estate funds where available. A beneficiary may agree to contribute or may receive less after tax and expenses, but that does not automatically transfer the legal responsibility for administering the estate. The will, the type of asset and HMRC’s payment arrangements can all matter, so a complicated estate should be reviewed by a suitably qualified adviser or solicitor.
The ISA allowance itself is separate from questions about income tax returns. For example, somebody receiving investment income from assets outside an ISA may need to consider who needs to file a self assessment tax return, depending on their income, employment position and HMRC’s instructions. Similarly, a person who has stopped working may ask, is universal credit taxable after losing work? Universal Credit is generally not treated as taxable income, but other earnings, savings and benefits can affect entitlement. These issues should be checked separately using current GOV.UK guidance because tax and benefit rules are not interchangeable.
Practical steps for the surviving spouse
Start by identifying every ISA held by the deceased, including cash ISAs, stocks and shares ISAs, innovative finance ISAs and lifetime ISAs where relevant. The executor should notify each provider, obtain a valuation at the date of death and ask whether the account has been registered as a continuing account of the deceased. Keep copies of the death certificate, grant of probate or letters of administration, the will and correspondence showing the provider’s valuation and APS calculation.
Next, decide whether the survivor wants to use the same provider or compare another eligible provider. Fees, investment choices, transfer procedures, dealing arrangements and withdrawal rules can differ, so the survivor should not treat an APS ISA as automatically identical to the deceased person’s account. A provider can explain its product and process, but it may not assess whether a particular investment is suitable; independent financial advice may be appropriate where the amount is substantial or the investments are complex.
The survivor should also record two separate figures: the assets inherited from the estate and the APS allowance available to subscribe. They are related but not the same thing. Money can be distributed to the survivor outside an ISA and later used for an APS subscription, provided the relevant rules and deadline are met. Keeping these records helps prevent a common administrative error in which ordinary ISA subscriptions are mistakenly counted as APS subscriptions, or the survivor assumes that receiving the estate automatically completes the ISA process.
If the deceased had made recent ISA subscriptions, held several providers’ accounts or died close to the end of a tax year, ask each provider how it has applied the statutory calculation. The survivor should also check whether the estate has outstanding tax, debts or valuation issues before spending inherited funds. Current figures, forms and deadlines should be confirmed with the ISA manager, HMRC or a qualified tax adviser rather than relying on a general explanation.
Key Takeaways
A spouse or civil partner can usually benefit from an Additional Permitted Subscription after the other person dies. This is best understood as a separate extra ISA allowance, not a direct transfer of the deceased’s ISA into the survivor’s name. The survivor may be able to use it even when the inherited cash or investments are distributed through the estate rather than transferred intact.
The original ISA may continue to receive tax treatment during estate administration, but that protection has limits and the account must eventually be closed or dealt with under the applicable rules. The ISA value can still form part of the estate for inheritance tax, while the APS is calculated through a separate process. A spouse exemption may be relevant, but it should not be assumed without checking the whole estate.
In practical terms, notify the provider promptly, obtain the date-of-death valuation, request the APS calculation and confirm the deadline before subscribing. Check whether the provider accepts APS subscriptions and whether its charges and investment range suit the survivor’s needs. Where the estate includes trusts, large investments, non-residence, disputes or significant tax liabilities, professional advice is sensible because the outcome depends on the specific facts and current law.
