Still have money to invest after the ISA deadline? Here are the best rates
The end of March and beginning of April usually see a rush of investments into ISAs before the end of the financial year (April 5).
Each year every person in the UK has a £20,000 allowance to invest into ISAs without paying tax on the interest earned and it's a case of use it or lose it - the allowance doesn't roll over into the next year.
Money can be split between cash and stock and shares ISAs and there are a number of different types of cash ISA on the market too - from easy access to fixed rate.

With interest rates rising - and therefore more people exceeding their personal allowance on interest earned from savings accounts - more people are looking to invest in an ISA of some sort.
ISAs also became more flexible in the 2024/25 year, as for the first time, the restriction on subscribing to only one ISA of each type per year was removed.
This means investors can subscribe to different ISA providers through the year as and when funds or favourable rates became available, so long as the £20,000 limit was not exceeded.
