If you've ever tried to figure out the difference between a 401(k), an IRA, and a Roth IRA, you're not alone. These are three of the most commonly used retirement accounts, and three of the most commonly confused.
Here's a clear breakdown of each one, when to use it, and how they work together.
The 401(k): Your Employer's Plan
A 401(k) is a retirement account sponsored by your employer. You contribute pre-tax dollars, which lowers your taxable income today. The money grows tax-deferred, meaning you pay taxes when you withdraw in retirement.
• 2026 contribution limit: $24,500 (plus $8,000 catch-up if you're 50+, and $11,250 super catch-up for ages 60 to 63)
• Many employers match contributions — this is essentially free money
• Investment options are limited to what your employer's plan offers
• You pay taxes on withdrawals in retirement
Rule of thumb: Always contribute at least enough to get your full employer match before doing anything else.
The Traditional IRA: More Flexibility, Same Tax Treatment
An IRA (Individual Retirement Account) is a retirement account you open yourself, independent of your employer. Like a 401(k), contributions may be tax-deductible and growth is tax-deferred.
• 2026 contribution limit: $7,500 (plus $1,000 catch-up if 50+)
• You choose your own investments — much more flexibility
• Tax deductibility phases out at higher incomes if you're covered by a workplace plan
• You pay taxes on withdrawals in retirement
The Roth IRA: Pay Taxes Now, Never Again
A Roth IRA is funded with after-tax dollars — meaning you don't get a deduction today. But the trade-off is powerful: your money grows tax-free, and you pay zero taxes on qualified withdrawals in retirement.
• 2026 contribution limit: $7,500 (plus $1,000 catch-up if 50+; same as Traditional IRA)
• Income limits apply: phases out above $153,000 (single) or $242,000 (married) in 2026
• No required minimum distributions (RMDs) during your lifetime
• You can withdraw contributions (not earnings) at any time without penalty
If you expect to be in a higher tax bracket in retirement than you are today — which is common in your 30s — the Roth IRA is often the better long-term choice.
Which One Should You Use?
Most people in their 30s should use all three in this order:
• First: 401(k) up to your employer match
• Second: Roth IRA up to the $7,500 limit (if eligible)
• Third: Back to your 401(k) up to the $24,500 limit
• Then: Taxable brokerage account for anything beyond that
The key is that these accounts are not either/or. They serve different purposes and work together as part of a complete strategy.
What If You Can't Max Out All of Them?
That's normal. Most people can't. Start with the 401(k) match, then add what you can to the Roth IRA. Even contributing $100-200 a month to a Roth IRA in your 30s adds up to a significant tax-free balance by retirement. Consistency matters more than perfection.

The opinions voiced in this material are for general information only and are not intended to provide specific advice or recommendations for any individual.
Contributions to a traditional IRA may be tax deductible in the contribution year, with current income tax due at withdrawal. Withdrawals prior to age 59 ½ may result in a 10% IRS penalty tax in addition to current income tax.
A Roth IRA offers tax deferral on any earnings in the account. Qualified withdrawals of earnings from the account are tax-free. Withdrawals of earnings prior to age 59 ½ or prior to the account being opened for 5 years, whichever is later, may result in a 10% IRS penalty tax. Limitations and restrictions may apply.
