Individual Retirement Account
A retirement plan. The traditional IRA allows individuals to contribute pretax earnings up to a maximum yearly allowance and to defer income taxes until the money is withdrawn after retirement. The Roth IRA allows individuals to contribute aftertax earnings and pay no taxes on future withdrawals. In contrast to a 401(k) plan, an IRA is funded entirely by the individual tax payer.
