A 401k is a retirement savings plan sponsored by an employer. It lets workers save and invest for retirement on a tax-deferred basis. Employees can contribute to their 401k through payroll deductions, and employers may match employee contributions up to a certain percentage.
it’s named for section 401(k) of the Internal Revenue Code, which governs its rules.
How Do 401(k) Plans Work?
401(k) plans are designed to encourage employees to save for retirement by allowing them to set aside a portion of their paycheck before taxes are deducted. The money that is set aside in the 401(k) plan can then be invested, and it grows tax-deferred until it’s withdrawn.
When an employee contributes to a 401(k) plan, they are typically able to choose how their money is invested. Common investment options include mutual funds, stocks, and bonds. Some 401(k) plans also offer annuities as an investment option.
Employees can usually start withdrawing money from their 401(k) plan when they reach age 59½ without having to pay a penalty. However, if withdrawals are made before age 59½, a 10% early withdrawal penalty may apply.

In addition, once an employee reaches age 70½, they must start taking required minimum distributions (RMDs) from their 401(k). RMDs are calculated based on the account balance and life expectancy of the account holder and must be taken by December 31 each year.

What Is a Traditional 401(k)?
A traditional 401(k) is a retirement savings plan that is sponsored by an employer and offers tax-deferred growth on investments. With a traditional 401(k), employees can choose to have a portion of their paycheck withheld and deposited into their 401(k) account. The money that is contributed to the account can then be invested, and it grows tax-deferred until it is withdrawn.
Traditional 401(k) plans are subject to annual contribution limits set by the IRS. For 2021, the contribution limit for employees is $19,500. Employers may also make contributions to their employees’ 401(k) accounts, but there are limits on how much they can contribute as well.
What Is a Roth 401(k)?
A Roth 401(k) is similar to a traditional 401(k), but with one key difference: contributions are made with after-tax dollars, which means that withdrawals in retirement are typically tax-free.
Like a traditional 401(k), a Roth 401(k) offers tax-deferred growth on investments and has annual contribution limits set by the IRS. For 2021, the contribution limit for employees is $19,500.
