401k vs IRA — Which Should Beginners Choose First?

By Harper Banks

---

Opening your first retirement account feels like standing in front of two doors, both promising a better financial future. One says "401k," the other says "IRA." Financial media rarely gives you a straight answer because — inconveniently — the right choice depends on your specific situation. But that's exactly what this post is for.

Benjamin Graham taught us that intelligent investing begins with understanding what you own. Before you contribute a single dollar, you should understand how each account works, what limits apply, and what your employer is (or isn't) offering you. Clarity comes before commitment.

Let's break down both accounts honestly, so you can make the right first move.

What Is a 401k?

A 401k is an employer-sponsored retirement plan. Your contributions are deducted directly from your paycheck, before taxes (for a Traditional 401k), which reduces your taxable income today. A Roth 401k option, when available, uses after-tax dollars — no tax break now, but tax-free withdrawals later.

2025 contribution limits:

• Employee contributions: $23,500
• Catch-up contributions (age 50+): $7,500 additional (total: $31,000)
• Enhanced catch-up (age 60–63, under SECURE 2.0): $11,250 additional (total: $34,750)
• Combined employer + employee maximum: $70,000

The 401k's biggest advantage — and the one most beginners overlook — is the employer match. If your company matches 50% of your contributions up to 6% of your salary, that's an instant 50% guaranteed return on every dollar you put in up to that threshold. Graham would recognize this immediately: an employer match is a margin of safety built right into your compensation.

There's no income limit to contribute to a 401k. High earners don't get phased out.

Drawbacks: You're limited to the investment options your employer offers. Many 401k menus are a grab-bag of high-expense mutual funds. You also can't open a 401k on your own — it requires an employer relationship.

What Is an IRA?

An IRA (Individual Retirement Account) is opened directly by you at a brokerage of your choice — Fidelity, Vanguard, Schwab, or any number of others. You choose your investments. This flexibility is the IRA's core strength.

Two main types:

Traditional IRA: Contributions may be tax-deductible depending on your income and whether you're covered by a workplace plan. Withdrawals in retirement are taxed as ordinary income. Required Minimum Distributions (RMDs) begin at age 73 (or 75 if you were born in 1960 or later, per SECURE 2.0).

Roth IRA: Contributions are made after tax. Qualified withdrawals — including earnings — are completely tax-free in retirement. No RMDs during your lifetime. This is the crown jewel for long-term compounders.

2025 IRA contribution limits:

• Under age 50: $7,000
• Age 50 and older: $8,000 (includes $1,000 catch-up)

Roth IRA income limits (2025):

• Single filers: Phase-out begins at $150,000, fully phased out at $165,000
• Married filing jointly: Phase-out begins at $236,000, fully phased out at $246,000

If you earn above these thresholds, you can't contribute to a Roth IRA directly (though the "Backdoor Roth" conversion strategy remains an option — consult a tax advisor about pro-rata rules).

The Beginner's Decision Framework

Here's the order Graham's discipline would suggest — maximize value, minimize waste:

Step 1: Capture every dollar of employer match. Your first retirement dollars should go into the 401k up to the full employer match. No debate. Leaving a match on the table is irrational from a value-investing standpoint — you're refusing a risk-free return.

Step 2: Open a Roth IRA next (if eligible). Once you've captured the match, redirect additional savings to a Roth IRA. You get full investment flexibility, tax-free growth, and no RMDs. For most beginners in the early-to-middle earning years, Roth beats Traditional — you're paying tax now at a lower rate rather than later at a potentially higher one.

Step 3: Return to the 401k if you still have room. Once the IRA is maxed at $7,000/year, go back to the 401k. The higher contribution limit ($23,500) lets you shelter significantly more income.

If your 401k has terrible, high-fee funds: Still capture the match — then prioritize the IRA over additional 401k contributions. Check your fund expense ratios. Any equity index fund charging over 0.20% annually is eating your compounding.

One More Thing: Tax Diversification

Owning both a Traditional and Roth bucket gives you retirement tax flexibility. When the market is up and your tax bracket is lower, you draw from Roth. When tax rates shift or you need a large one-time withdrawal, you have options. A single-account retirement is brittle. Diversifying tax treatment is just as important as diversifying asset classes.

Common Beginner Mistakes to Avoid

Mistake 1: Not contributing anything because you can't contribute the maximum. A $100/month contribution is better than zero. Start small, automate the increase.

Mistake 2: Leaving your IRA in cash. Simply opening an IRA and not choosing investments is extremely common. Your money sits in a default money market earning near nothing while the market compounds without you. Log in, pick a fund, and invest.

Mistake 3: Contributing to a Roth IRA when you're in a high tax bracket. If you're earning $150,000 as a single filer, you're in the 22% or 24% bracket. A Traditional IRA deduction (if eligible) or pre-tax 401k contribution may be worth more today than tax-free withdrawals later. Run the math or ask your CPA.

Mistake 4: Forgetting the IRA contribution deadline. IRA contributions for a tax year can be made up to April 15 of the following year. If you forgot to contribute in 2025, you have until April 15, 2026 to make that $7,000 contribution and potentially claim the deduction.

Use a Stock Screener to Build Your IRA Portfolio

Once you've opened an IRA, you need to fill it with quality investments. A value screener filters for low P/E, strong balance sheets, and consistent earnings — the fundamentals Graham spent a career teaching.

Actionable Takeaways

• Always contribute to your 401k up to the full employer match first — it's a guaranteed return no other investment can match.
• Open a Roth IRA after capturing the match — tax-free growth and no RMDs make it the most flexible retirement vehicle for most beginners.
• Know the 2025 limits: 401k employee max is $23,500; IRA max is $7,000 ($8,000 if 50+).
• Check fund expense ratios in your 401k — high fees silently destroy compounding over decades; anything over 0.20% for a broad index fund is a red flag.
• Tax diversification matters — owning both Roth and Traditional accounts gives you withdrawal flexibility in retirement when tax rates are uncertain.
