The 401(k) plan is a type of employer-sponsored retirement plan named after a section of the United States Internal Revenue Code. A 401(k) plan allows a worker to save for retirement while deferring income taxes on the saved money or earnings until withdrawal. As an employee benefit, a 401(k) must be sponsored by an employer, typically a private sector corporation

401(k) plans are retirement plans that are designed to encourage long-term retirement savings by employees. 401(k) plans need to meet a variety of rules contained in Section 401(k) of the Internal Revenue Code. But these be plans are very popular among companies and employees.

Here are the key features of such plans:

Employer contributions: The employer can contribute to the plan (subject to certain limits) for the employee's benefit, and the employee doesn't have to pay immediate income tax on that contribution.

Employee contributions: The employee can elect to contribute a portion of his or her salary to the plan, and then the employee doesn't have to pay immediate income tax on that contributed salary.

Investment of contributions: The employee can choose how to invest contributed money (in stocks, bonds, and other qualifying investments, for example).

Tax deferral: The taxes on the contributions and the plan's investment earnings are deferred until the employee withdraws them (generally at retirement).

Loan: In some instances, a participant may be able to take a loan against the 401(k) account, and as long as the employee repays the loan before taking a distribution from the plan, the funds remain tax deferred.

Withdrawals: Unless the employee is age 59½ or anther exception applies (such as total disability), withdrawals by an employee may be subject to both a 10 percent penalty and regular income tax.

Rollovers: Penalties and taxes generally do not apply if the employee changes jobs and "rolls over" his or her sums in the plan to the new employer's qualified plan that accepts rollovers. Penalties and taxes can also be avoided in certain circumstances for rollovers into an IRA.

When an employee leaves a job, the 401(k) account generally stays active for the rest of his or her life, though the accounts must begin to be drawn out beginning at age 70-1/2. The nature of a 401(k) plan can be drafted to accommodate certain employer needs, subject to qualifying with the appropriate tax rules.

Hello Tesmian,

To simplify & summarize this topic,  401(k) plan is a type of tax-qualified deferred compensation plan in which an employee can elect to have the employer contribute a portion of his or her cash wages to the plan on a pre–tax basis. These deferred wages  are not subject to income tax withholding at the time of deferral, and they are not reflected on your Form 1040 since they were not included in the taxable wages on your Form W-2. However, they are included as wages subject to social security, Medicare, and federal unemployment taxes.

The amount that an employee may elect to defer to a 401(k) plan is limited. Therefore, your elective contributions may be limited based on the terms of your 401(k) plan.

With regards,

Steve
