What are the trading rules for Isa's?

Trading within an Individual Savings Account (ISA) in the UK allows individuals to buy and sell investments without incurring capital gains tax on profits. There are two main types of ISAs: Cash ISAs and Stocks and Shares ISAs. The annual contribution limit for ISAs is set by the government, and for the 2023/2024 tax year, it is £20,000. It's important to note that once funds are withdrawn from an ISA, they cannot be re-deposited within the same tax year without affecting the allowance.
