What is a stocks and shares junior ISA?
A stocks and shares junior ISA is a tax-efficient investment account for children under 18, allowing parents or guardians to invest up to £9,000 annually in shares, funds, or bonds for long-term growth. Unlike a cash junior ISA, it offers potential for higher returns through market investments but comes with risks like market fluctuations. The funds grow tax-free, shielding gains from income tax or capital gains tax, which is particularly beneficial for building a nest egg until the child turns 18.
Eligibility and rules
To open a junior stocks and shares ISA, the child must be under 18 and a UK resident, with only one parent or guardian managing it. Contributions can come from anyone, but the total per tax year cannot exceed the £9,000 allowance for 2025/26, as set by HM Revenue & Customs (HMRC). For more on the basics, see our guide on what is a junior isa. Withdrawals are restricted until age 18, except in exceptional circumstances like terminal illness.
Benefits versus cash ISA
Stocks and shares junior ISAs historically deliver average annual returns of 5-7% over 10+ years, far outpacing the 1-3% from cash options, according to data from the FTSE All-Share Index via Trust Intelligence. This makes them ideal for high-growth potential, though volatility means short-term losses are possible. In contrast, cash junior ISAs provide stability but lower growth in a low-interest environment. Parents weighing options should consider risk tolerance, as detailed in our pillar on the best junior isa choices.
