What Is a 401(k)?

What is a 401(k)?

A 401(k) is a tax-advantaged retirement savings plan offered by employers to help employees save for retirement. Named after a section of the U.S. Internal Revenue Code, it is a defined contribution plan where employees can contribute a percentage of their income, and employers may match these contributions.

Types of 401(k) Plans

  1. Traditional 401(k):
    • Contributions are made with pre-tax income, reducing your taxable income in the contribution year.
    • Withdrawals in retirement are taxed as ordinary income.
  1. Roth 401(k):
    • Contributions are made with after-tax income, so there is no immediate tax benefit.
    • Qualified withdrawals, including earnings, are tax-free in retirement.

Key Benefits of a 401(k)

  • Employer Matching: Many employers match employee contributions, often up to a percentage of the employee’s salary, providing a risk-free boost to your savings.
  • Tax Advantages:
    • Traditional: Immediate tax deduction.
    • Roth: Tax-free withdrawals in retirement.
  • Compound Growth: Contributions grow over time through reinvested earnings, significantly increasing the total value of the account.
  • Automatic Savings: Contributions are deducted directly from your paycheck, simplifying the savings process.

Contribution Limits (2024)

  • Employee Contributions: Up to $23,000 annually.
  • Catch-Up Contributions (Age 50+): Additional $7,500.
  • Combined Employee and Employer Contributions: $69,000 (or $76,500 for employees 50 and older). 

How to Start a 401(k)

  1. Contact Your Employer: Confirm if a 401(k) plan is available and inquire about employer matching.
  2. Enroll: Complete the necessary paperwork.
  3. Choose Investments: Select options that match your risk tolerance and retirement timeline. Common choices include mutual funds and target-date funds.
  4. For Self-Employed Individuals: Explore solo 401(k) plans, which offer similar tax advantages and higher contribution limits.

401(k) Withdrawals and Rules

  • Before Age 59½: Withdrawals are subject to a 10% penalty and taxes unless you meet certain hardship exemptions.
  • After Age 59½: Withdrawals from a Traditional 401(k) are taxed as income, while Roth 401(k) withdrawals are tax-free if qualified.
  • Required Minimum Distributions (RMDs): Start at age 73 for Traditional 401(k)s.

Pros and Cons of a 401(k)

Pros:

  • Employer matching enhances savings.
  • Tax advantages (immediate or future).
  • Automated paycheck deductions encourage consistent saving.

Cons:

  • Early withdrawals incur penalties.
  • Limited investment options compared to brokerage accounts.
  • May not fully cover retirement needs.

Managing Your 401(k) When Changing Jobs

When leaving a job, you generally have four options:

  1. Leave the Account with Your Former Employer:
    • Suitable if the plan is well-managed and offers good investment options.
    • Risks include forgetting about the account or heirs being unaware of it.
  1. Roll Over to an IRA:
    • Provides access to a wider range of investments.
    • Must be completed within 60 days to avoid taxes and penalties.
  1. Transfer to Your New Employer’s 401(k):
    • Maintains tax-deferred status and simplifies management if you prefer fewer accounts.
  1. Withdraw the Funds:
    • Not recommended due to taxes and penalties unless it’s a financial necessity.

401(k) vs. Brokerage Accounts

  • 401(k): Retirement-focused, tax-advantaged, and often includes employer matching.
  • Brokerage Account: Offers more investment flexibility but lacks tax advantages or contribution limits.

The Bottom Line

A 401(k) plan is a powerful tool for retirement savings, offering tax advantages, employer contributions, and the potential for substantial growth through compounding. To maximize its benefits, contribute consistently and take full advantage of any employer match. Diversify your retirement strategy by considering both Traditional and Roth 401(k) options, and consult a financial advisor to tailor your plan to your goals and circumstances.
