The Short Answer

If your employer offers a 401k match, contribute enough to get the full match. That part is not optional, it is free money. After that, here is the general rule of thumb most people follow:

• Lower income now, expect higher income later → lean Roth IRA
• Higher income now, expect lower income in retirement → lean traditional 401k
• Not sure, or somewhere in the middle → split your savings between both

Now let's get into why.

What a 401k Actually Is

A 401k is a retirement account your employer sets up and manages. Money comes straight out of your paycheck before you ever see it, which makes saving automatic instead of something you have to remember to do.

Key facts for 2026:

• You can contribute up to $24,500 of your own salary.
• If you're 50 or older, you can add a catch-up contribution of $8,000, for a total of $32,500.
• If you're between 60 and 63, you get a higher "super catch-up" of $11,250 instead, bringing your total to $35,750.
• Combined employee and employer contributions can go as high as $72,000 for the year.
• Most 401k contributions are pretax. That means the money is taken out before income tax is applied, which lowers your taxable income for the year you contribute.
• You pay income tax later, when you withdraw the money in retirement.

Many employers also offer a Roth 401k option, which flips the tax treatment: you contribute after-tax money now, and withdrawals in retirement are tax-free. The contribution limits are the same as a traditional 401k.

The part that matters most: the employer match. A lot of companies match a percentage of what you put in, often 50 cents to a dollar for every dollar you contribute, up to a certain percentage of your salary. If your employer offers a 4% match and you contribute less than 4%, you are simply giving up money your employer was ready to hand you. No other investment decision in this article matters as much as capturing that match in full.

What a Roth IRA Actually Is

A Roth IRA is not tied to your employer at all. You open it yourself through a brokerage like Fidelity, Vanguard, or Schwab, and you control where the money is invested.

Key facts for 2026:

• You can contribute up to $7,500 for the year.
• If you're 50 or older, you can add a catch-up contribution of $1,100, for a total of $8,600.
• Contributions are made with after-tax money. You don't get a tax break now.
• Qualified withdrawals in retirement, including all the growth your investments earned, are completely tax-free.
• There are income limits. In 2026, your ability to contribute starts shrinking once you earn more than $153,000 as a single filer, or $242,000 if you're married filing jointly. It disappears completely above $168,000 (single) or $252,000 (married filing jointly).
• Unlike a 401k, a Roth IRA has no required minimum distributions during your lifetime, so the money can sit and keep growing tax-free for as long as you want.

If your income is too high to contribute directly, some people use a workaround called a backdoor Roth IRA. That involves putting money into a traditional IRA first and converting it to a Roth afterward. It works, but it has tax details worth checking with a professional before you try it.

Why the Tax Timing Question Matters So Much

The entire 401k vs Roth IRA debate really comes down to one question: do you want your tax break now, or later?

With a traditional 401k, you lower your taxable income this year. If you're in a high tax bracket right now, that deduction is worth more in dollar terms today. The tradeoff is that you'll owe income tax on every dollar you withdraw in retirement, including all the growth.

With a Roth IRA, you pay tax on the money before it goes in, at whatever rate applies to you right now. The upside is that decades of growth come out completely untaxed later. If you're early in your career and in a lower tax bracket than you'll likely be in later, this usually works out better.

There's no way to know your exact future tax bracket today, which is exactly why a lot of people simply use both accounts instead of betting everything on one guess.

A Simple Way to Decide

Run through these questions in order:

1. Does your employer offer a 401k match? If yes, contribute at least enough to get the full match before doing anything else. This step comes before any tax strategy.
2. Do you expect to earn more, or less, in retirement than you do right now? If less, lean traditional 401k. If more, or if you're not sure, lean Roth IRA.
3. Is your income under the Roth IRA limit? If you're over the limit, a Roth IRA isn't directly available to you, so extra savings beyond your 401k match will need to go into a traditional IRA, a backdoor Roth, or a regular taxable brokerage account instead.
4. Do you have room to save beyond the match? If yes, split the rest between maxing out your Roth IRA and adding more to your 401k, in whichever order makes sense for your tax situation.

The Bottom Line

A 401k and a Roth IRA aren't really competitors. They solve two different problems. The 401k gets you the employer match and a much bigger contribution limit. The Roth IRA gets you tax-free growth and full control over your investments, as long as your income qualifies.

Most people who build a strong retirement do this in the simplest possible order: capture the full 401k match, then fill up a Roth IRA if they're eligible, then go back and add more to the 401k if there's still room to save. It's not complicated. It just takes showing up and doing it every paycheck.
