Additional Permitted Subscriptions ISA

With an Additional Permitted Subscriptions (APS) ISA you can benefit from your partner’s previous tax-free savings allowance.

At a glance

  • You’ll get a variable interest rate of 2.25% tax-free p.a./AER.
  • You’ll be able to start saving with as little as £1, up to £500,000 (but it does depend on the amount of ISA savings held by your late partner).
  • You can take your money out at any time. We won’t charge you and you don’t need to let us know beforehand.
  • We’ll pay your interest yearly.

Yes. The interest rate is variable, so it can go up or down at any time.

If the interest rate on your account goes down, and the balance in your account is £100 or more, we’ll write to you to let you know.

To find out more information about how we might change your interest rate, and how we’ll let you know, please read sections 5d and 5e of our General Terms and Conditions.

All our savings interest rates are available in our branches and online.

This example is provided to help you compare savings accounts and does not take into account your own circumstances.

How do I open and manage my account?

Opening your account

  • You can only open this account by post by completing and returning the application form to us.
  • We'll then work out your APS allowance (see ‘Additional Information’ to find out more).

Managing your account

  • You'll manage this account over the phone or by post.
  • Once your account is open you can view your account online through our savings portal. To register go to www.westbrom.co.uk/savingsportal.

How to put money into your account

  • Money must be paid in within three years from the date your partner passed away, or 180 days after administration of the estate is completed, whichever is later.
  • Any money to be paid in after this must be paid in with a completed APS Eligibility Declaration Form.
  • The most you can have in your APS ISA is equal to your APS ISA allowance up to £500,000.
  • Payments into your account can be made by cheque or by completing the withdrawal form if the ISA isn't with the West Brom.

Can I withdraw money?

  • Yes. You can take money out at any time.
  • Once money has been taken out of your APS ISA, it can’t be paid back into the account.
  • If the APS ISA is closed before the full Additional Permitted Subscription allowance is used, the unused allowance will be lost.

Additional information

We pay your interest tax-free. This means you will not pay income tax on the interest you earn.

How the APS allowance is calculated depends on the date of death of the ISA account holder as shown in the table below:

Where the ISA account holder died between 3 December 2014 and 5 April 2018

The APS allowance equals the value of the ISA(s) at the date of death.

Where the ISA account holder died on or after 6 April 2018

Any ISA(s) held can stay open as a continuing account of a deceased account holder, referred to here as a continuing ISA. The APS allowance equals the higher of the value of the ISA(s) at the date of death or the value of the ISA(s) at the date the ISA(s) ceased to be a continuing ISA.*

*The account will stop being a continuing ISA on the earlier of the following:

  • When the administration of the deceased’s estate is complete.
  • When the ISA is closed.
  • 3 years after the date of death.

Where more than one ISA is held with an ISA provider, the value at the date of closure will be the total value of all ISAs at the date of closure of each account.

Moving your APS allowance from elsewhere?

If you want to move an APS allowance held elsewhere to the West Brom, please complete an  APS Transfer Authority Form and send this with your application form.

Please note, it is only the allowance that is transferred, not any funds.

Once the allowance transfer is complete you will be able to pay in up to your new APS allowance.

Please read the Specific Terms and Conditions for this account and our General Terms and Conditions.

Did you know?

APS allowance – is the amount that you can subscribe to your APS ISA. It is an allowance that equals the value of the ISA(s) held by your late spouse/civil partner.

Tax-free – means you will not pay income tax on the interest you earn.

AER – stands for Annual Equivalent Rate and illustrates what the interest rate would be if interest was paid and added each year. All rates quoted are correct as at 12/02/2025.

Identification – when you open an account with the West Brom we may need to confirm your identity. For full details on why this is required and the types of identification accepted please refer to the Society’s ‘Important information on identification’ leaflet.

Personal Savings Allowance – the Personal Savings Allowance was introduced on 6 April 2016 and means that the first £1,000 of overall savings interest for basic rate taxpayers and the first £500 for higher rate taxpayers are free from income tax. (There is no allowance for additional rate taxpayers.) From this date, we stopped deducting any tax from the interest paid to you (ISAs are tax-free). You are responsible for paying any tax due to HM Revenue & Customs (HMRC). For further information about the Personal Savings Allowance, please contact your local HMRC office.

Protection for savers – your eligible deposits with the West Brom are protected up to a total of £85,000 by the Financial Services Compensation Scheme, the UK’s deposit guarantee scheme. Any deposits held above the limit are unlikely to be covered. You can visit www.fscs.org.uk for more information.
