Saving for your child: Junior ISA, your own ISA or savings account?
"Saving for the kids" can mean very different things. A gift they get at 18. Help with costs before then. A flexible family pot for whatever comes next.
Before you compare rates or investments, answer two questions: whose money will it be, and when should it be reachable?
The account follows from the answers, not the other way round.
A Junior ISA: a gift that belongs to the child
A Junior ISA can hold cash or investments. For 2026/27, up to £9,000 in total can go into a child's Junior ISAs in the tax year. The limit is per child, not per person paying in or per account type. HMRC: Junior Individual Savings Accounts, Overview, HMRC: Junior Individual Savings Accounts, Add money to an account.
Your child must be under 18 and live in the UK, although some children of Crown servants living abroad can also qualify. A child can't have a Junior ISA and a Child Trust Fund at the same time, but the trust fund can be transferred into a Junior ISA. HMRC: Junior Individual Savings Accounts, Overview.
Anyone can pay in, but the money is the child's. It normally can't be taken out before 18, with a few narrow exceptions. The child can take over managing the account at 16, and it becomes an adult ISA at 18. HMRC: Junior Individual Savings Accounts, Add money to an account, HMRC: Junior Individual Savings Accounts, Manage an account.
That ownership point isn't small print. You can say what you hope the money is for. You can't make a Junior ISA guarantee it goes on university or a deposit.
It also means it isn't a spare emergency fund for the household.
Cash and stocks-and-shares Junior ISAs are different choices
The ISA is the wrapper. What's inside sets the risk.
A cash Junior ISA earns interest. A stocks-and-shares Junior ISA holds investments. The wrapper shields interest, dividends and growth from UK tax. It doesn't make the value certain. HMRC: Junior Individual Savings Accounts, Overview.
Cash loses buying power when prices rise faster than interest. Investments can fall, and charges eat into returns. A long time before the money is needed doesn't remove the chance of loss. If you're not sure how much risk suits you, get regulated financial advice rather than picking on the back of a rosy growth chart. Financial Conduct Authority: Is it the right investment for you?.
Your own ISA: you keep ownership
If you save in your own ISA, the money stays yours, even if you've mentally labelled it "for the kids". For 2026/27, the adult ISA allowance is £20,000 across all your ISAs, subject to the rules for each type. Using it for this eats into allowance you might want for your own saving. HMRC: Individual Savings Accounts.
Note for 2027/28: the government plans to cap what under-65s can put into cash ISAs at £12,000 a year from 6 April 2027. People aged 65 or over would keep a £20,000 cash ISA limit. This is subject to final regulations, so check the current rules before the new tax year. HMRC: The Individual Savings Account (Amendment) Regulations 2026, technical consultation.
You keep the choice of when to hand the money over. But don't describe it as already the child's. It's part of your own finances, with whatever that means for your situation.
Access depends on the product. An easy-access cash ISA isn't a fixed-term one, and a Lifetime ISA has its own withdrawal rules. "ISA" doesn't mean every version suits flexible family spending. HMRC: Individual Savings Accounts, Withdrawing your money.
A children's savings account: read the terms
A savings account outside an ISA can work well if you need access before 18. But who owns the money, who can withdraw it, the interest rate and any restrictions all depend on the product and how it's set up. Check the terms rather than assuming every children's account is the same.
There's usually no tax to pay on children's savings, but one rule catches money from parents. If a child gets more than £100 of interest in a tax year from money a parent gave them, all of that interest, not just the part over £100, is generally treated as the parent's for tax. Whether tax is due then depends on the parent's allowances. The rule doesn't apply to Junior ISAs, or to gifts from grandparents, other relatives or friends. HMRC: Interest on savings for children.
That's a reason to keep track of who paid in, not a reason to assume every small account creates a tax bill.
The practical differences side by side
Question | Junior ISA | Parent's own ISA | Children's savings account |
|---|---|---|---|
Who owns the money? | Child | Parent | Check the account terms |
Access before 18? | Normally no | Depends on the ISA's terms | Depends on the account terms |
Separate child allowance? | Yes | No: uses the parent's allowance | No ISA allowance used |
What matters most? | It's a gift, reachable at 18 | You keep control and flexibility | Access, interest and tax treatment |

Start with an amount you understand
Example: £50 a month for exactly 17 years is £10,200 paid in: £50 × 12 × 17. That leaves out interest, investment returns, fees, inflation and tax. It's a total of contributions, not a forecast of what the account will be worth.
You don't need to fill an allowance for saving to count. And you don't need to put child savings ahead of essential bills or keeping the household steady.
Decide who owns it and when it can be reached. Then decide cash or investments. The starting question is what the money is for, not which account has the nicest name.
