ISA allowance
Important information - please keep in mind that the value of investments can go down as well as up, so you may get back less than you invest. Tax treatment depends on individual circumstances and all tax rules may change in the future. This information is not a personal recommendation for any particular investment. If you are unsure about the suitability of an investment you should speak to one of Fidelity’s advisers or an authorised financial adviser of your choice. Withdrawals from a Junior ISA will not be possible until the child reaches 18.
What is the ISA allowance?
The ISA allowance in a nutshell is how much a person can put into their ISA each tax year. The ISA allowance for this year is £20,000. The tax year runs from the 6 April to 5 April the following year. And you have until midnight to invest your money. If you do not use all your ISA allowance in one year, you’re not able to carry this allowance over to the next year so it’s important to make the most of each tax year.
The best way to think of an ISA is as a tax 'wrapper'. Each year, you're entitled to a specific allowance or limit, which is protected by the ISA wrapper. This means you won't be charged tax on the interest or capital gains you earn, offering greater growth potential on your investments, although this is not guaranteed.
