Parents saving for a child's future face a choice that isn't always obvious: lock money away in a Junior ISA in the child's name, or keep it in a standard savings account or investment in your own name where you retain control. Both have real trade-offs.

The Junior ISA allowance

The Junior ISA allowance for 2026/27 is £9,000, and the government has confirmed it will remain at that level until at least 2030/31. Anyone can contribute — not just parents — but the account must be opened by a parent or legal guardian, and a child can hold one cash JISA and one stocks and shares JISA at a time. Growth inside a JISA is entirely tax-free, and unlike the adult ISA allowance, it doesn't affect your own personal ISA limit at all.

The catch: it belongs to the child, not you

This is the single biggest consideration. Money placed in a Junior ISA legally belongs to the child, and it automatically becomes accessible to them at age 18, with no parental control over how it's spent from that point. For some families that's exactly the point — a guaranteed, protected pot the child can't touch early and parents can't be tempted to dip into. For others, particularly if there's any concern about a young adult managing a lump sum responsibly, that lack of ongoing control is a genuine drawback.

The alternative: saving in your own name

Keeping the money in your own savings account or ISA means you retain full control over when and how it's used — useful if your plans might change, if you want flexibility to use the money for something else entirely, or if you're uncomfortable handing an 18-year-old unrestricted access to a potentially large sum. The trade-off is that any growth counts toward your own tax position and your own £20,000 annual ISA allowance if you want it to grow tax-free, competing with your own retirement and other savings goals for that same allowance.

A practical middle ground

Some families split the difference: using their own ISA allowance for money they want full control over, while contributing smaller, more affordable amounts to a Junior ISA specifically intended as a starting-adult-life gift — first car, university costs, a house deposit contribution — accepting that it becomes the child's outright at 18.

Checklist: deciding what's right for your family

• Decide how much control you want to retain — a Junior ISA cannot be reclaimed by parents once opened, regardless of circumstances.
• Check whether you'll use your full £20,000 personal ISA allowance first — a JISA's £9,000 limit is additional, not a replacement.
• Consider a cash JISA for shorter timeframes, and a stocks and shares JISA if the child is young enough (generally 5+ years) to ride out market volatility for potentially higher long-term growth.
• Think about the child's maturity and your comfort level with them controlling a potentially large sum at 18.
• Remember grandparents and other family members can contribute too, within the same £9,000 combined annual limit.

How other countries approach saving for children

The US 529 plan offers tax-advantaged growth for education-specific savings, but unlike a JISA, the account owner (usually a parent) retains control indefinitely and can even change the beneficiary — a materially different control structure than the UK's JISA, where control transfers automatically. Canada's Registered Education Savings Plan (RESP) similarly keeps the account under parental control while adding government top-up grants, again avoiding the UK's automatic-transfer-at-18 feature. This makes the JISA relatively unusual in giving children unconditional legal ownership at a fixed age regardless of what it's ultimately used for.

Key Numbers

• £9,000 — Junior ISA allowance for 2026/27
• £20,000 — separate adult ISA allowance, unaffected by JISA contributions
• 18 — age at which JISA funds become the child's own, with no parental control
• 2030/31 — confirmed year the £9,000 JISA limit will remain unchanged until
