A Traditional 401(k) is a retirement savings plan offered by employers that helps you save money for retirement while reducing your current taxes. Created by Congress in 1978, it gets its name from section 401(k) of the tax code.
Here’s how it works: You choose to have part of your paycheck put directly into your 401(k) account before taxes are taken out. This money, plus any contributions from your employer and investment growth, stays in your account tax-free until you withdraw it in retirement.
Congress created 401(k) plans to encourage Americans to save for retirement. With fewer companies offering traditional pensions, 401(k) plans have become the main way most private-sector workers save for their retirement years.
These plans are regulated by several government agencies to protect participants:
When you contribute to a Traditional 401(k), that money comes out of your paycheck before income taxes are calculated. If you earn $80,000 and contribute $12,000, you only pay income tax on $68,000. This could save you $2,400-3,600 or more in taxes each year, depending on your tax bracket.
Once money is in your 401(k), it grows without being taxed each year. You don’t pay taxes on investment gains, dividends, or interest until you withdraw the money. This allows your savings to grow faster than they would in a regular investment account.
When you withdraw money from your Traditional 401(k) in retirement, you pay income tax on it then. Many people are in a lower tax bracket in retirement, so they may pay less tax overall.
The IRS has increased the limits for 2026:
The new “super catch-up” provision for ages 60-63 recognizes that these are often peak earning years when people can save more aggressively for retirement.
Many employers help boost your retirement savings by adding money to your 401(k):
The most common type. Your employer might match 50 cents for every dollar you contribute, up to a certain percentage of your salary. For example, if you earn $60,000 and contribute 6% ($3,600), your employer might add another $1,800.
Some employers contribute based on company profits, regardless of whether you contribute.
Starting in 2024, some employers can make matching contributions directly to your Roth 401(k) account. If you elect this option, the employer match becomes taxable income to you but grows and can be withdrawn tax-free in retirement.
As of 2024, employers can treat your student loan payments as if they were 401(k) contributions for matching purposes. This means you can get employer matching contributions even while paying off student loans instead of contributing to your 401(k).
Always contribute at least enough to get the full employer match—it’s free money that instantly increases your retirement savings.
Your own contributions are always 100% yours. But employer contributions might become yours gradually over time through “vesting.” Common vesting schedules include:
If you leave your job before you’re fully vested, you keep your contributions but may lose some employer contributions.
Important change (effective 2025): Plans established after December 29, 2022, must automatically enroll eligible employees unless they opt out. This means:
Even if you’re automatically enrolled, review your contribution rate and investment choices to ensure they align with your retirement goals.
Starting in 2026, part-time employees who work 500+ hours per year for two consecutive years must be allowed to participate in their employer’s 401(k) plan. Previously, this required three consecutive years.
Your 401(k) money needs to be invested to grow over time. Most plans offer several investment options, typically mutual funds that invest in:
A simple, effective approach is to build a diversified portfolio using low-cost index funds that give you exposure to global markets, combined with more conservative investments based on your comfort with risk and timeline.
401(k) plans are designed for retirement, so access while working is limited:
Loans: You might be able to borrow up to half your balance (maximum $50,000):
Emergency Withdrawals (New for 2024): Up to $1,000 annually for unforeseeable emergencies:
Hardship Withdrawals: For serious financial needs like medical bills or avoiding foreclosure:
After Age 59½: You can make withdrawals without the 10% penalty, though regular income tax still applies.
You have several options:
Penalty-Free Withdrawals: Start at age 59½, though you’ll pay regular income tax.
Required Minimum Distributions (RMDs): Must start taking minimum withdrawals at age 73 (increased from 72). The age will increase to 75 starting in 2033.
Still Working Exception: If you’re still working at age 73 and don’t own more than 5% of the business, you can delay RMDs from your current employer’s plan until you retire.
Reduced Penalties: If you miss an RMD, the penalty is now 25% of the missed amount (down from 50%), and only 10% if you correct it within two years.
If you take money out before age 59½, you’ll usually pay:
Exceptions include:
Many employers now offer both types:
Important: Starting in 2026, high earners (those making over $150,000) must make catch-up contributions to Roth accounts only.
Both types have the same contribution limits and investment options. Many people contribute to both for tax diversification.
Federal law provides strong protections for your 401(k):
Congress passed the SECURE 2.0 Act in 2022, making significant improvements:
If you earn more than $150,000 annually, prepare for changes:
To build retirement security with your 401(k):
Many plans offer target-date funds that automatically adjust your investment mix as you approach retirement. These can be an excellent “set it and forget it” option for many investors.
Some plans allow withdrawals while still employed, typically after age 59½. This can provide flexibility for Roth conversions or other strategic moves.
Recent laws have expanded when you can access your 401(k) during emergencies while minimizing penalties and taxes.
Your 401(k) strategy should coordinate with your expected Social Security benefits and other retirement income sources.
A Traditional 401(k) remains one of the best tools available for building retirement savings, made even better by recent law changes. The increased contribution limits, new super catch-up provisions for those aged 60-63, elimination of RMDs for Roth portions, and emergency withdrawal options provide unprecedented flexibility and saving opportunities.
While automatic enrollment will help more Americans start saving, the real key to retirement security is understanding your options and making informed decisions about contribution levels, investment choices, and tax strategies. The combination of immediate tax savings, potential employer contributions, decades of tax-free growth, and enhanced withdrawal flexibility makes the 401(k) an essential component of retirement planning.
Start early, contribute consistently, invest wisely, take advantage of the increased limits and new features, and let time and compound growth build your retirement security. With the recent improvements, your 401(k) can do more for your retirement than ever before.
