Junior ISA vs Child Trust Fund: What Are Your Options in 2026?

If you are saving for a child's future, two products often come up: the Junior ISA (JISA) and the Child Trust Fund (CTF). While CTFs are no longer available to new applicants -- they were replaced by JISAs in November 2011 -- millions of children still hold CTF accounts, and their families have options. This guide explains both products, how they compare, and what to do if your child has a CTF.

What Is a Junior ISA?

A Junior ISA is a tax-free savings or investment account for children under 18 who are resident in the UK. All growth, interest and income within a JISA is completely exempt from income tax and capital gains tax. The child cannot access the money until they turn 18, at which point the JISA automatically converts to an adult ISA.

Key JISA facts for 2026/27:

• Annual allowance: GBP 9,000 per child (unchanged from recent years)
• Types: Cash JISA or Stocks and Shares JISA
• Can hold one of each type simultaneously
• Contributions from parents, grandparents, relatives and friends all count toward the same GBP 9,000 limit
• The child cannot withdraw funds before age 18 (except in cases of terminal illness)
• At 18, the child gains full control and the account becomes a standard adult ISA

What Is a Child Trust Fund?

The CTF was a government savings initiative for children born between 1 September 2002 and 2 January 2011. The government made an initial contribution (GBP 250 at birth, with additional top-ups for lower-income families and at age 7). CTFs were closed to new accounts from November 2011.

If your child was born during the eligible period, they almost certainly have a CTF -- even if you never contributed to it or forgot about it. HMRC automatically opened accounts for families who did not set one up themselves. Many of these "forgotten" CTFs have been sitting with government-appointed providers for years.

How to Find a Lost CTF

If you are unsure where your child's CTF is held, HMRC provides an online tool at gov.uk to locate it. You will need the child's National Insurance number (issued before their 16th birthday). Once located, you can either manage the existing CTF or transfer it to a JISA.

Transferring a CTF to a JISA

Since April 2015, families have been able to transfer CTF savings directly into a Junior ISA. The process works as follows:

1. Open a JISA with the provider of your choice
2. Ask the JISA provider to initiate the transfer -- you do not request it from the CTF provider
3. The CTF provider must complete the transfer within 15 business days
4. Once transferred, the CTF is closed and all funds sit in the JISA

Important: The transfer does not use up any of the GBP 9,000 annual JISA allowance. The full balance moves across regardless of its size, and new contributions in the same tax year still have the full GBP 9,000 limit available.

Why Transfer to a JISA?

There are several good reasons to move a CTF to a JISA:

Wider provider choice. CTFs are offered by a limited number of providers, and many charge higher fees than competitive JISA providers. Stocks and shares JISAs are available from a wide range of platforms with competitive annual management charges.

Better investment options. Many CTF accounts, especially older ones, hold funds with limited investment choices. A JISA on a modern platform gives access to global index funds, bonds and diversified portfolios.

Simpler management. If you have multiple children with different accounts, consolidating onto a single JISA platform makes administration easier.

Potentially lower charges. Even a 0.5% difference in annual management charge can compound to a significant sum over 18 years.

Cash JISA vs Stocks and Shares JISA

Both types of JISA are available as standalone accounts or in combination.

Cash JISA: Works like a savings account. Interest is paid tax-free. Suitable if you need certainty and are saving over a shorter timeframe. Rates vary by provider; competitive cash JISAs in 2026 offer around 4--5% AER.

Stocks and Shares JISA: Invests in funds, shares or bonds. Over an 18-year horizon, equities have historically outperformed cash -- but there is no guarantee, and the value can fall. Suitable for parents comfortable with investment risk over the long term.

Many financial advisers suggest a Stocks and Shares JISA for children who are young (more than 10 years to 18) and switching to a Cash JISA as the child approaches adulthood to lock in gains.

Tax Advantages Explained

No income tax or CGT is paid on any growth or income within a JISA. This is particularly important for families who might otherwise be caught by the "parental settlement" rules: if a parent gives money to a child and the resulting interest exceeds GBP 100 per year, it is normally taxed as the parent's income. Inside a JISA, this rule does not apply -- all interest and growth is completely sheltered.

What Happens at Age 18?

When a child turns 18, the JISA automatically converts to an adult ISA. The former child has full access to the funds and can do whatever they wish with the money. The account retains its ISA wrapper, meaning no tax is due on withdrawal. In the tax year of conversion, the young adult also gains their own annual ISA allowance of GBP 20,000 in addition to any JISA contributions made before their birthday.

LISA vs JISA for Children?

The Lifetime ISA (LISA) is not available for children -- the minimum age to open one is 18. A LISA offers a 25% government bonus (up to GBP 1,000 per year) and is designed for first home purchase or retirement. Once a child turns 18 and converts their JISA, they could consider opening a LISA alongside their adult ISA if buying a first home is a near-term goal.
