401(k) plans have many benefits, and some are less well-known than others. A 401(k) is a type of retirement plan offered by an employer in which the employee can defer part of their paycheck into a retirement account to grow for their retirement years. Now, let’s get into some 401(k) benefits you may not know about.
What’s New in 2025 (Quick Highlights)
Before we dive into the benefits, here are some important 401(k) changes for 2025:
- Higher contribution limits: You can contribute up to $23,500 this year, or $31,000 if you’re age 50 or older (thanks to a $7,500 catch-up).
- No more Roth 401(k) RMDs: Starting in 2024, Roth 401(k)s no longer require lifetime required minimum distributions (RMDs).
- Automatic enrollment: Many new plans are required to automatically enroll eligible employees beginning in 2025, making it easier to save.
- New safety valves: Certain penalty-free withdrawals are now available for emergencies and domestic abuse situations.
What Is A 401(k) Plan and How Does It Work?
A 401(k) is an employer-sponsored retirement plan that allows you to contribute a portion of your paycheck into investments for your future. Contributions are often deducted automatically, and many employers add a matching contribution—essentially extra money—if you save.
2025 401(k) contribution limits:
- Under age 50: $23,500
- Age 50+: $31,000 (includes a $7,500 catch-up)
If you are self-employed with no employees, then you can have a similar account called a Solo 401(k).
Is A 401(k) Worth It?
Yes—if your employer offers one, it’s usually one of the most powerful ways to save for retirement. Between the tax benefits, the potential employer match, and decades of compound growth, it’s designed to help your money work harder for you.

1: 401(k) Tax Advantages
Why it matters: Every 401(k) contribution has built-in tax benefits—you just decide whether you want the benefit now or later.
Traditional 401(k): Contributions reduce your taxable income today. Money grows tax-deferred and is taxed as ordinary income when withdrawn.
Roth 401(k): Contributions are made with after-tax dollars. Withdrawals in retirement are tax-free.
Please read our blog about Roth 401(k) vs Traditional 401(k) to learn about each option and decide which is best for you.
Big update: As of 2024, Roth 401(k)s no longer require lifetime RMDs. That means you can leave the money invested for as long as you want without being forced to withdraw at a certain age.
2: Employer Matching = Free Money
Why it matters: Employer matches can boost your retirement savings rate significantly.
Example match structures you may see:
“50% match up to 7%” → You contribute 7% of your pay, and your employer adds 3.5%.
“100% match up to 5%” → You contribute 5%, and your employer adds another 5%.
Tip: Check your plan’s vesting schedule, which determines when employer match dollars officially become yours. Some companies grant matches immediately, while others phase them in over several years.
I recently conducted a LinkedIn poll and was thrilled that 94% of respondents contribute enough to their 401(k) to receive their employer match! It’s great to see so many people taking advantage of this free money and setting themselves up for a more substantial retirement.
3: You Can Take Your 401(K) With You
Changing jobs doesn’t mean losing your retirement savings. There are many options for what to do with your 401(k) when you leave a job.
Leave it with your old employer’s plan (if allowed).
Roll it over to your new employer’s 401(k).
Roll it into an IRA for more investment flexibility.
Cash it out—though this is usually the worst option because of taxes, penalties, and lost growth.
If you have an outstanding loan when you leave your job, the balance may be treated as a distribution. However, you now have until your tax filing deadline (plus extensions) to roll it over and avoid penalties—more flexibility than the old 60-day rule.
4: Compound Interest Works In Your Favor
Why it matters: Compounding is what turns small contributions into large balances over time.
For example:
Contribute $5,000 at age 25.
Leave it invested for 40 years at a hypothetical 6% annual return.
By age 65, it could grow to around $65,000—over 90% of which is growth, not contributions.
This isn’t a guarantee—markets fluctuate—but it shows why time in the market is so powerful.
The younger you start saving for retirement, the longer your money has to compound. Things like what you invest in and fees can make a difference, so ensure you know your options before deciding on your 401(k) investment portfolio.
5: 401(k) Contributions Are Automatic
Once you set up your 401(k), contributions are deducted automatically from your paycheck.
Choosing a percentage of salary (instead of a flat dollar) means your contributions increase naturally as your income grows.
Many new plans will also include automatic enrollment and auto-escalation features starting in 2025, unless you opt out. These features are designed to help you save more with less effort.
6: 401(k) Fiduciary Benefits
The Employee Retirement Income Security Act (ERISA), sets standards of conduct for all employer sponsored retirement plans. One of the requirements is that those who manage an employee benefits plan and its assets must act as plan fiduciaries. Some of the responsibilities of the plan fiduciary are:
- Acting solely in the interest of plan participants and their beneficiaries and with the exclusive purpose of providing benefits to them;
- Carrying out their duties prudently;
- Following the plan documents (unless inconsistent with ERISA);
- Diversifying plan investments; and
- Paying only reasonable plan expenses.
What does this mean for you as an employee? Your plan assets are being managed in the best interests of the plan participants. Every plan must have at least one fiduciary. And this fiduciary must follow the rules set out by ERISA. For example, they cannot charge exorbitant fees, or only have high-risk, high-cost investment options.
What does this not mean? It does not guarantee that your invested money is protected from stock market downturns.
7: Emergency Access To Funds (If Needed)
401(k)s are meant for retirement, but certain situations allow earlier access:
Loans: You may be able to borrow up to the lesser of $50,000 or 50% of your vested balance. Repayments usually come directly from payroll. If you leave your job, unpaid loans may be treated as distributions, but you can roll over the balance by your tax deadline to avoid penalties.
Hardship withdrawals: Allowed for specific emergencies, such as medical expenses or disability. These withdrawals are taxable and may face a 10% penalty if you’re under 59½, though some exceptions apply.
Emergency personal expense distribution: Up to $1,000 once per year, taxable but penalty-free, with the option to repay within three years.
Domestic abuse distribution: Up to the lesser of $10,000 (indexed after 2024) or 50% of your vested balance. Taxable but penalty-free, with the option to repay.
These options can provide a lifeline—but dipping into retirement savings should be a last resort.
8: Protection From Creditors
ERISA funds (qualified employer-sponsored retirement accounts like 401(k) plans) are generally protected from creditors. If you need to file for bankruptcy or owe a creditor a large amount of money, the creditor cannot go after your plan assets regardless of how much money you have in there.
The two exceptions are if the creditor is the federal government or you owe money to an ex-spouse in a Qualified Domestic Relations Order. Your funds can be seized to satisfy these debts.
