Child Trust Fund Maturity: A Complete 2026 Guide
Your Child Trust Fund matured at 18? Learn how to find a lost CTF, what tax you pay, and how to move the money into an ISA or pension in 2026/27.
Quick answer
A Child Trust Fund matures on the holder's 18th birthday, at which point the young adult takes full control. The money stays tax-free while inside the CTF wrapper. You can withdraw it, leave it where it is, or transfer it into an adult ISA without using your GBP 20,000 annual allowance. The first step is always to find the account and check the balance.
What is a Child Trust Fund?
A Child Trust Fund was a long-term, tax-free savings account introduced by the government for children born between 1 September 2002 and 2 January 2011. The state opened each account with a starting voucher - typically GBP 250, or GBP 500 for children in lower-income households - and some children received a second payment at age seven. Parents, family, and friends could then add money over the years.
The scheme closed to new accounts in January 2011, when Junior ISAs took over. But millions of existing CTFs are still live, and they continue to mature one cohort at a time as each child turns 18. If you were born in this window, you almost certainly have one, even if you have never seen a statement.
What happens at maturity?
On the morning of the holder's 18th birthday the account legally matures. Three things change:
- Control passes fully to the account holder. Parents and guardians lose any say; the 18-year-old can now make every decision.
- The CTF wrapper ends. The account stops being a Child Trust Fund. Providers handle this differently - some automatically roll the balance into a matured-CTF ISA, others move it to a holding account pending instructions.
- The clock starts on your decision. Whatever you decide, doing it promptly protects both the tax treatment and the interest rate on the money.
At 16, by the way, the child could already take over day-to-day management of the account, choosing how it is invested. But withdrawal rights only begin at 18.
How to find a lost Child Trust Fund
If you do not know who holds your CTF, you are far from alone. The fix is simple and free.
- Go to the official HMRC Child Trust Fund tracing service on gov.uk.
- Sign in or provide your details, including your National Insurance number.
- HMRC tells you which provider holds the account.
- Contact the provider directly to confirm the balance and your options.
Parents or guardians can trace an account on behalf of a child under 16. The service costs nothing, so steer well clear of any company that offers to find your CTF for a fee or a percentage of the balance - they are simply charging you for something HMRC does for free.
The tax treatment: why a CTF is valuable
Inside the wrapper, a Child Trust Fund behaves like an ISA. All interest, dividends, and capital growth are free of UK Income Tax and Capital Gains Tax, and none of it needs to be declared on a tax return. That tax shelter is the single biggest reason to think carefully before cashing out.
Once you withdraw the money into an ordinary account, the picture changes. Future interest then counts towards your Personal Savings Allowance, and any future gains on investments could use your annual Capital Gains Tax exemption of GBP 3,000 for the 2026/27 tax year. The Annual Exempt Amount is modest, so for larger sums keeping the money in a tax wrapper matters.
| Where the money sits | Income Tax on growth | CGT on growth | Annual contribution limit |
|---|---|---|---|
| Inside the CTF | None | None | N/A (matured) |
| Adult ISA after transfer | None | None | GBP 20,000 total across ISAs |
| Lifetime ISA | None | None | GBP 4,000 (counts towards GBP 20,000) |
| Ordinary savings account | Counts to PSA | Counts to GBP 3,000 exemption | None |
Crucially, transferring a matured CTF into an adult ISA through the provider's transfer process does not consume your GBP 20,000 annual ISA allowance. That is a deliberate rule to protect savers, so always use the formal transfer route rather than withdrawing the cash and paying it in yourself.
Your four options at maturity
1. Withdraw the cash
You can simply take the money. This makes sense if you have an immediate, genuine need - tuition costs, a car for work, a rental deposit. Spending it on items that lose value, though, means giving up years of compound growth that the money could otherwise earn.
2. Move it into a cash ISA
If you want safety and easy access, a cash ISA keeps the money tax-free and protected from market swings. Returns will be modest, but the capital does not fall in value. This suits anyone who expects to need the money within a few years.
3. Move it into a stocks and shares ISA
For money you can leave untouched for five years or more, a stocks and shares ISA keeps growth tax-free and aims for higher returns over time. Markets rise and fall, so this carries risk, but the long horizon of an 18-year-old works in its favour.
4. Open a Lifetime ISA
A Lifetime ISA (LISA) is designed for a first home or retirement. The government adds a 25% bonus on what you pay in, up to GBP 1,000 a year on a maximum GBP 4,000 contribution. If buying a first home is on your horizon, routing some of a matured CTF into a LISA can be one of the most powerful uses of the money. Note the LISA GBP 4,000 limit sits within your overall GBP 20,000 ISA allowance, and withdrawals for anything other than a first home or after age 60 carry a penalty.
A GBP 1,000 matured CTF spent on a depreciating purchase is gone. The same GBP 1,000 left to grow tax-free could keep compounding for decades. Even a few years of patience changes the outcome significantly.
A worked illustration of compound growth
Suppose a matured CTF holds GBP 1,500 and the holder leaves it in a tax-free wrapper rather than spending it. The power of compounding means that even modest annual growth adds up over time, because each year's growth itself earns growth the following year. Exact outcomes depend on the rate and the time invested, so model your own numbers before deciding.

Step-by-step: what to do this month
- Trace the account. Use the HMRC tool if you do not know the provider.
- Check the balance and where it sits. Confirm whether it has already rolled into a matured-CTF ISA or a holding account.
- Decide your goal. Immediate spending, short-term saving, long-term investing, or a first-home deposit.
- Pick the destination. Cash ISA, stocks and shares ISA, or Lifetime ISA - and use the formal transfer process to preserve the tax wrapper.
- Compare rates. A forgotten holding account often pays poor interest, so shop around.

- Paying a tracing firm. HMRC traces CTFs for free; commercial services add no value.
- Withdrawing then re-depositing. This can waste your annual ISA allowance. Always transfer directly.
- Ignoring the account entirely. Unclaimed CTFs can sit for years earning very little. The money is yours - claim it.
- Spending without a plan. A one-off windfall feels small, but invested early it can become the foundation of a first home or pension.
Frequently asked context
If your CTF was never topped up beyond the government voucher, the balance may be only a few hundred pounds. That is still worth claiming and growing. If parents contributed regularly, the figure can run into several thousand pounds, where the choice of wrapper matters even more. Either way, the same principles apply: find it, keep it tax-free where you can, and match the destination to your goals.

A matured Child Trust Fund is a quiet head start that millions of young adults are entitled to. Find it for free through HMRC, keep it inside a tax-free wrapper unless you have a real need for the cash, and choose a destination - cash ISA, stocks and shares ISA, or Lifetime ISA - that fits your plans. The earlier you act, the more the money can work for you.
Frequently asked questions
When does a Child Trust Fund mature?
A Child Trust Fund matures on the holder's 18th birthday. From that date the account holder gains full legal control of the money and can withdraw it, leave it where it is, or transfer it elsewhere. CTFs were set up for children born between 1 September 2002 and 2 January 2011, so the first accounts began maturing in September 2020. The account stops being a CTF at 18 and the provider will usually move it to a holding account if you take no action.
How do I find a lost Child Trust Fund?
Use the free HMRC tracing tool on gov.uk. You will need your National Insurance number and basic personal details, and HMRC will tell you which provider holds your account. You do not need to know the provider in advance. Parents or guardians can also trace an account for a child under 16. The service is free, so avoid any third party that charges a fee to find your CTF for you.
Do I pay tax on a Child Trust Fund?
No. While the money sits inside a Child Trust Fund it grows free of UK Income Tax and Capital Gains Tax, just like an ISA. The interest, dividends, and growth are not taxed and do not need to be declared. Tax only becomes a consideration after you withdraw the money into an ordinary account, where future interest counts towards your Personal Savings Allowance and any gains may use your annual CGT exemption.
Can I move a matured CTF into an ISA?
Yes. Once a CTF matures at 18 you can transfer the proceeds into an adult ISA, and a matured CTF transfer does not count against your GBP 20,000 annual ISA allowance if done correctly through the provider's transfer process. Many providers automatically convert a matured CTF into a stocks and shares ISA or cash ISA in your name. Check with your provider whether the rollover is automatic or whether you must instruct it.
What happens if I do nothing when my CTF matures?
If you take no action, the provider moves the money out of the CTF wrapper, usually into a protected holding account or a matured-CTF ISA in your name. The cash is still yours and remains tax-free if held in an ISA wrapper, but in a plain holding account future interest may become taxable. It is worth contacting the provider to confirm where your money has gone and what interest rate, if any, it is earning.
How much is usually in a matured Child Trust Fund?
It varies widely. The government paid an initial voucher, typically GBP 250 (or GBP 500 for lower-income families), and a second payment at age seven for some children. With no further contributions and modest growth, many accounts are worth a few hundred to around a thousand pounds. Where parents added regular top-ups over 18 years, balances can run into several thousand pounds. Check your statement or the provider portal for your exact figure.
Should I withdraw the money or leave it invested?
That depends on your goals. If you need the money for education, a car, or a deposit, withdrawing is reasonable. If you can leave it, moving it into a Lifetime ISA can earn a 25% government bonus towards a first home or retirement, or a stocks and shares ISA keeps it growing tax-free. Spending it on depreciating items gives up years of potential compound growth, so weigh short-term needs against long-term value.
Can parents access a child's Child Trust Fund?
No. Parents and guardians can manage a CTF while the child is under 18 - choosing investments and adding money - but they cannot withdraw funds for their own use. At 16 the child can take over management of the account, and at 18 they gain full control and the right to withdraw. The money legally belongs to the child throughout. Only in very limited cases, such as terminal illness, can early access be granted.
Is a Junior ISA the same as a Child Trust Fund?
No, but they are similar. Junior ISAs replaced CTFs for children born from 3 January 2011 onwards. Both are tax-free children's savings wrappers that the child controls at 18. A child cannot hold both at once, though a CTF can be transferred into a Junior ISA, which often offers better rates and wider investment choice. If you still hold a CTF, comparing it against a Junior ISA before maturity can be worthwhile.
What should I do first when my CTF matures?
First, locate the account and check the balance through your provider or the HMRC tracing tool. Second, decide whether you need the cash now or can keep it invested. Third, choose a destination: a cash ISA for safety, a stocks and shares ISA for growth, or a Lifetime ISA for a first home. Acting promptly matters because money left in a non-ISA holding account can lose its tax-free status and may earn poor interest.
