Retirement accounts refer to investment accounts specifically designed for retirement savings. These accounts come with tax benefits to encourage individuals to save for retirement.

The most common types of retirement accounts in the United States include 401k plans, individual retirement accounts (IRAs), Roth IRAs, and Simplified Employee Pension (SEP) plans.

The contributions made to these accounts are often tax-deductible, and the investment earnings grow tax-deferred until withdrawn in retirement. However, early withdrawals before the age of 59 ½ may be subject to penalties and taxes.
