How much money can you invest in an ISA?
Before each tax year, the UK Government sets the ISA allowance limit for the following tax year. For the 2024/25 tax year, the current ISA allowance is £20,000. This means you can invest up to £20,000 in a combination of different ISAs (except for the Lifetime ISA). For example, you may choose to invest £20,000 into an Innovative Finance ISA or choose to split the Investment across each type.
You currently have no legal requirement to declare any interest or capital gains on any investments you have gained through an ISA.
What are the different types of ISAs?
Don’t invest unless you are prepared to lose money. This is a high-risk investment. You may not be able to access your money easily and are unlikely to be protected if something goes wrong. Take 2 minutes to learn more.
What happens if you invest more than the ISA allowance limit within the same tax year
If you accidentally invest into more than one of the same type of ISA, you should contact your ISA provider as soon as possible and also get in touch with the HMRC.
By contacting both, you may be entitled to reclaim the excess payment. If you cannot reclaim it, you may lose the tax relief on the excess payment which means you will have to pay income tax on that limit.
