Is it possible to transfer an Adult ISA to your baby? Many parents ask this question, and the short answer is ‘no’. However, there is a straightforward alternative: setting up an ISA in your baby’s name. The vehicle for doing this is called a Junior ISA. So, if you have questions around ISA for a baby, the place to get these questions answered is here. 

An Adult ISA and a Baby’s ISA Are Separate Wrappers 

Adult ISA transfers can only be facilitated between adult (or ‘standard ISA’) providers; ISAs can’t be transferred between parents and children or vice-versa. A Junior (or baby ISA) is a product that is opened in the child’s name. The money belongs to the child and not the parent, though the parent (or guardian) is the one responsible for facilitating payments into the account, and parents can contribute from their own savings up to the annual limit. The key thing parents need to bear in mind is that paying into a child’s Junior ISA (or JISA) does not eat into one’s own adult ISA allowance. 

What You Can Do: Open a Junior ISA and Start Contributing 

The JISA allowance for the financial year 2026/27 is £9,000. It’s important to note that the £9,000 allowance is not per ISA (Junior ISAs come in two types, Cash and Investment). Here at the Children’s ISA, we are an Investment Junior ISA specialist. This means the funds invested on behalf of the child are invested in stocks and bonds. Regardless of the type of Junior ISA you choose (cash or investment) the money is locked away on the child’s behalf until they reach adulthood. You can open a Junior ISA with The Children’s ISA in minutes, and their money starts working tax-free straight away.

Can You Transfer an Existing Junior ISA? 

For parents who already have a Junior ISA for their child and want to switch, it is easy for parents to switch a JISA on behalf of their child between providers. It is also important to note that switching between Junior ISA providers can be done without losing the tax-free status of the product. The transfer of a child’s ISA must be done via the provider; funds cannot be withdrawn except in exceptional circumstances, and transfers must be made in full. If your child is older and has a Child Trust Fund (CTF), the full balance can be transferred to a JISA, which then closes the CTF. 

What About the Child Trust Fund?

Child Trust Funds were set up by the government in January 2005 and phased out in 2011. A child cannot hold a JISA and a CTF at the same time. The Junior ISA provider can facilitate the transfer of a CTF to a JISA. Parents of older children may have a legacy CTF, so it is worth checking, and this money could be under-utilised and lying dormant. 

A Note for Those Thinking Bigger: Gifting Into a Baby’s ISA 

As we said before, a JISA allowance is completely separate from the parents’ own £20,000 limit. So, assuming a household has two parents and two children, £58,000 can be invested tax-free per year. Anyone aged 18+ can contribute to a child’s JISA account, and not just the parents. Grandparents, aunts and uncles and even family friends can contribute to a child’s JISA account, but the combined total of these contributions cannot exceed the £9,000 tax-free limit. 

So the answer to the question can I transfer an ISA to my baby is no. But the better question could be, how can I start building up a tax free next egg for my child from scratch?
