IRA. A tax-deferred retirement account for an individual that permits individuals to set aside money each year, with earnings tax-deferred until withdrawals begin at age 59 1/2 or later (or earlier, with a 10% penalty). IRAs can be established at a bank, mutual fund, or brokerage. Only those who do not participate in a pension plan at work or who do participate and meet certain income guidelines can make deductible contributions to an IRA. All others can make contributions to an IRA on a non-deductible basis. Such contributions qualify as a deduction against income earned in that year and interest accumulates tax-deferred until the funds are withdrawn. A participant is able to roll over a distribution to another IRA or withdraw funds using a special schedule of early payments made over the participant's life expectancy.
