<human>: What's the difference between the 401k, the 403b, the 457, and the IRA?
<bot>: The 401(k) is a retirement savings plan offered by employers. It allows employees to save for retirement on a pre-tax basis. Contributions are made from an employee's salary before taxes are taken out. The 403(b) is similar to the 401(k), but it is offered through tax-exempt organizations such as universities or charities. The 457 is a type of deferred compensation plan that offers tax benefits to certain highly compensated individuals. An Individual Retirement Account (IRA) is a retirement savings account available to anyone who earns income. Contributions to an IRA are not taxed until they are withdrawn in retirement.
