'Junior individual savings account (Junior ISA)'
Junior Individual Savings Accounts (Junior ISAs) were set up by the government in 2011 to encourage people to save for their children by offering a tax-efficient 'wrapper' within which their investments are free of tax on dividends, interest, and capital gains. Any child in the UK aged under 18 can have an ISA in their name. The government sets the amount you can invest each year; check the HMRC website at https://www.gov.uk/junior-individual-savings-accounts for the current allowance.
