Product information

  • About this policy

    We all want to give our child the very best start in life, and with our Junior Investment ISA (JISA) you could do just that. 

    Our JISA gives you the ability to save tax-free, with plans starting from £10 a month or a single lump sum of £100. You can save up to £9,000 in the current tax year and once opened, top ups can be made by anyone at any time within the annual limit.

  • What are they?

    JISAs were first introduced by the government in November 2011, as a way for parents or guardians to set up a long-term tax-free savings account for their child(ren).

    There are two types of JISA available, a stocks and shares JISA and a cash JISA. We offer a stocks and shares JISA in the form of a with-profits insurance policy, which is designed for the medium to long-term and matures on the child's 18th birthday. We refer to our JISA as an Investment JISA because of the way we invest (in our with-profits fund) - which includes property, bonds and fixed interest as well as the stock market. The fund is managed to provide a low-medium risk investment.

  • Who are they for?

    Any child under the age of 18 who is a UK resident can have a JISA opened for them by a parent or guardian.

    Children born between 1st September 2002 and 2nd January 2011 may have a Child Trust Fund (a long-term tax-free savings account for children set up by the government). A child cannot have both a Child Trust Fund (CTF) or a JISA, however a CTF can be transferred to a JISA.

    Unsure if your child has a CTF? Visit the website for further information.

  • How are bonuses calculated?

    Unlike banks who add interest to their accounts, we aim to add bonuses to our members' policies. The amount of bonus credited to the policy will depend on the amount invested (known as policy premiums) and, as bonuses are calculated daily (after deducting charges) on a compound basis and added monthly (net of charges), the length of time the policy has been running.  There is also the possibility of a final bonus on maturity of the JISA. Bonuses are not guaranteed. More information can be found in our FAQs.

  • Any guarantees?

    We will guarantee a minimum final amount of 100% of the premiums in the event of death, terminal illness or maturity (when the child reaches 18), providing the premiums have been invested for five years. No guarantee is given in respect of premiums paid within five years of the date of the claim or maturity.

  • Can I make withdrawals and top up my JISA?

    You cannot withdraw any monies from a JISA until the child reaches 18. When the plan reaches the maturity date, the proceeds will be paid to the child and not the parent/guardian.

    Although a parent or guardian needs to open the JISA, you'll be pleased to know that anyone (grandparents, friends, family members) can top up a child's JISA - perfect for birthdays or Christmas.

    Please note, if you are not paying in to the child's JISA on a monthly basis, the minimum additional investment (top up) is £50.

  • What about charges?

    We will deduct 1.50% of the value of the JISA fund each year to cover administration costs and expenses. More information can be found in our FAQs.

Frequently asked questions

Our most commonly asked questions surrounding the Junior Investment ISA can be found below.

The JISA will mature when the child reaches 18 years of age. At this time the child can withdraw the funds or rollover the investment in to an adult ISA in their own name. Withdrawals are not allowed at any time before age 18.

Every child can hold both a stocks and shares JISA and a cash JISA at any one time with the same or different product providers, providing the overall investment allowance is not exceeded (see below).

The government sets the investment limits and the current allowance for the tax year which runs from 6 April to 5 April is £9,000 or £750 per month. This amount can be split between a stocks & shares JISA and a cash JISA, providing the overall limit is not exceeded in the tax year (6 April to 5 April). The minimum in the Sheffield Mutual Investment JISA is £10 per month or a single lump sum of £100.

Yes, providing you don’t exceed the maximum annual investment allowance (above) you can add to the JISA at any time during the tax year. If you are not subscribing on a monthly basis by direct debit the minimum additional investment is £50. Any person can subscribe to the child’s JISA - including parents, grandparents, family members and friends. All subscriptions will be classed as gifts to the child, which means that once premiums have been added, under normal circumstances (except on early death or the diagnosis of a terminal illness), the funds cannot be withdrawn until the child reaches the age of 18.

The child must be a resident in the UK when the JISA is opened (or a dependant of a crown servant living overseas). Although the funds belong to the child (the ‘policyholder’) at all times, the policy must be opened and operated by a 'registered contact' (someone who will manage the plan) until the child reaches at least 16 years of age. The registered contact will be the person with parental responsibility for the child, with the child able to take over their plan, if they wish, at age 16.

Depending upon the performance of our investments, we will declare a bonus rate annually in March and this will be applied to the JISA at the end of the tax year. The amount of bonus credited to the policy will depend on the amount invested (known as policy premiums) and, as bonuses are calculated daily (after deducting charges) on a compound basis and added monthly (net of charges), the length of time the policy has been running. The registered contact will receive a statement during April each year setting out the amount of bonus and present value of the JISA. There is also the possibility of a final bonus on maturity of the JISA. Bonuses are not guaranteed.

We will deduct 1.50% of the value of the JISA policy fund each year to cover administration and expenses. The annual charge is normally deducted from the declared annual bonus amount before it is added to the policy. However, it would be deducted from the policy fund should the bonus amount be less than the annual charge.

Yes, you can transfer previous years’ JISA subscriptions in whole or in part from another provider to us, without it affecting the annual investment allowance. Current tax years’ JISA subscriptions must be transferred in full. Transfers can be made either way (i.e. cash to stocks and shares or stocks & shares to cash) and are subject to the child not having more than one JISA of each type at the end of the transfer process. This means that part transfers can only be made to another type, for example, part cash JISA transferred to a stocks & shares JISA. The minimum investment is £100, so if your transfer amount is less, you will need to make it up to £100.

Yes, those with a CTF may transfer to a JISA. This must be the whole amount as partial transfers are not allowed. This type of transfer will not count towards the child’s JISA allowance. Don't worry about contacting the current provider, we'll take care of everything for you.

A CTF may be transferred even if, at the time of the transfer, the child would not meet the normal UK residency conditions for a JISA.

Yes, you can stop or vary the level of payments at any time. However, we retain the right to terminate the policy in circumstances where you have not invested the minimum initial premium of £100 for single premium JISAs or £10 per month for 12 months for regular premium JISAs.

Just like adult ISAs, no tax is payable on any of the income or capital gains a child receives from JISA savings and investments. In addition, no tax is payable by a subscriber to the policy on any income or gains generated by the JISA, even where that income exceeds the £100 limit which normally applies to gifts from parents. This is based on current tax legislation, which may vary in the future.

We invest in a range of different assets with the aim of providing a higher return in the medium to long-term than is achievable with a bank or building society account. Sheffield Mutual's with-profits fund is managed to provide a low to medium risk investment, appealing to anyone with a more cautious approach to investment. Our investments include property, shares of UK companies, government gilts, corporate bonds, commercial mortgages and cash.

However, should you wish to withdraw (after maturity) or transfer funds from the JISA during adverse investment conditions, the Society may apply a Market Value Reduction to the policy fund, which could in some circumstances, result in the child receiving back less than you paid in. Therefore, the amount you receive on repayment is not guaranteed and you should only invest in an Investment JISA if you are prepared to take some risk to increase the potential returns.

You'll be pleased to know that we seek to adopt an ethical approach to investing and it is our policy not to invest knowingly or directly in industries relating to armaments, tobacco, gambling or pornography.

In the unfortunate event of early death or the diagnosis of a terminal illness, we will pay 101% of the policy value to the child’s estate or personal representative. Closure of the JISA in relation to a terminal illness must be agreed by HM Revenue & Customs. Bonus will be paid tax-free up until the date of death.

In the unfortunate event of the death of the parent/guardian, we will need to see the original (or certified copy) death certificate. Another person with parental responsibility for the child (or the child is aged 16 or over) should then apply to become the person responsible for the plan.

Provided the monies come from a UK bank account, you and your family and friends can continue to pay money in, subject to the JISA limits.
