The ISA allowance for tax year 21/22 will remain unchanged at £ 20,000.00.
The LISA (Lifetime ISA) allowance will also remain unchanged at £ 4,000.00. Note the withdrawal charge has been moved back up to 25% for withdrawals in tax year 21/22, having been previously reduced to 20% for 20/21.
The JISA allowance has also remained unchanged at £ 9,000.00.
You may invest in more than one ISA product in the same tax year, but cannot exceed your yearly allowance. Also note that you cannot invest in more than ISA product of the same type in the same tax year, e.g., you can subscribe £ 10,000 to a Cash ISA and £ 10,000.00 to a Stocks and Shares ISA, but not £ 10,000.00 to two separate Cash ISA’s in the same tax year.
The tax year runs from April 6th to April 5th, hence you have up until April 5th 2022 to utilise your 21/22 ISA allowance.
