An Individual Savings Account (ISA; ) is a class of retail investment arrangements available to residents of the United Kingdom. It qualifies for a favourable tax status. Payments into the account are made from after-tax income. The account is exempt from income tax and capital gains tax on the investment returns, and no tax is payable on money withdrawn from the scheme either. Cash and a broad range of investments can be held within the arrangement, and there is no restriction on when or how much money can be withdrawn. Funds cannot be used as security for a loan. Until the Lifetime ISA was introduced in 2017 it was not a specific retirement product, but any type can be a useful tool for retirement planning alongside pensions.
