Citizens of the United Kingdom (UK) have available to them a tax-privileged financial product that is referred to as an individual savings account (ISA). A cash ISA is a type of ISA that is used to hold cash, it is opposite to shares of stock. A cash ISA, earns interest tax-free up to a certain deposit amount.

First introduced in 1999
In 1999 cash ISAs were first introduced as a replacement for other types of tax-exempt accounts. They were designed such that they might be more accessible than the accounts they replaced, and so that they may benefit a wider range of people.
Another type of ISA
Per year only one cash ISA may be opened, although there is another type of ISA that is used in order to hold shares of stock, one of which may also be opened every tax year. Since the debut of the ISA there have been changes in limits placed on the balances of these accounts, and they will probably change again.
Rule to remember
As with any tax shelter, when opening and maintaining a cash ISA there are several rules that must be observed. Perhaps the one that is considered to be most important to remember is that there are contribution limits on cash ISAs, which don’t take withdrawals into account.

For example, if the contribution limit is 3,000 British Pounds, and a person contributes 1,500 Pounds, then it is withdrawn by him during the same tax year, then the account can still only have 1,500 Pounds more deposited into it. This is only if the withdrawal never occurred. If this rule is forgotten then significant tax advantages can be lost.
Cash transfer should be conducted by the managers
Another important guideline that a person has to follow is that he or she has to exercise care in transferring a cash ISA from one manager to another. When a transfer is made, it should be conducted by the managers themselves due to the reason that if the account holder does it instead of manager then it is treated as a withdrawal for tax purposes. By doing this the purpose of making the transfer in the first place is possibly defeated.
While now there is no existence of several distinctions between cash ISAs, still when looking for a place to invest your money it is wise to do some comparison shopping . There is a variation in interest rates and the accessibility of the accounts depending on the managing institution.
