401(k) vs. Roth IRA: Which Should You Fund First?

Two Accounts, Two Tax Deals

A traditional 401(k) is a workplace plan — you can only have one if your employer offers it. Contributions come straight out of your paycheck before income tax is calculated, so a $500 contribution might only shrink your take-home pay by $380 or so. The money grows untaxed for decades, and then every dollar you withdraw in retirement is taxed as ordinary income. In the IRS's framing, traditional 401(k) contributions are made with before-tax dollars, and distributions are includible in gross income later. You're not avoiding the tax; you're deferring it — and betting it'll be smaller then.

A Roth IRA flips the deal. You open it yourself at any brokerage, fund it with money you've already paid tax on, and get no deduction today. In exchange, the account grows tax-free, and qualified withdrawals in retirement — earnings included — are never taxed. Per the IRS, a qualified distribution requires the account to have been open at least five years and you to be 59½ or older (or disabled, or a first-time homebuyer up to a $10,000 lifetime limit). One more structural difference matters: a 401(k) limits you to the menu of funds your plan picked, while an IRA is an open brokerage account where you can hold almost any fund or stock — which often means lower fees and more control.

The 2026 Numbers

For 2026, the IRS raised the 401(k) employee deferral limit to $24,500, up from $23,500 in 2025. If you're 50 or older, you can add a catch-up contribution of $8,000 on top of that, and under a SECURE 2.0 provision, workers aged 60 through 63 get a higher catch-up of $11,250 instead. The IRA limit — traditional and Roth combined — rose to $7,500 for 2026, plus a $1,100 catch-up if you're 50 or older. All of these come from the IRS's annual cost-of-living notice (Notice 2025-67).

Roth IRAs add one wrinkle a 401(k) doesn't have: an income ceiling. For 2026, the ability to contribute to a Roth IRA phases out between $153,000 and $168,000 of modified adjusted gross income for single filers and heads of household, and between $242,000 and $252,000 for married couples filing jointly. Below the range, you can contribute the full amount; inside it, a reduced amount; above it, you can't contribute directly at all. A 401(k) — traditional or Roth — has no income limit, which is one reason it remains the workhorse account for high earners.

Side by Side: 401(k) vs. Roth IRA

• •Who provides it — 401(k): your employer; you can only join if your workplace offers a plan. · Roth IRA: you; open one yourself at virtually any brokerage.
• •Tax on the way in — 401(k): traditional contributions are pre-tax and cut your taxable income today. · Roth IRA: contributions are after-tax; no deduction now.
• •Tax on the way out — 401(k): withdrawals taxed as ordinary income. · Roth IRA: qualified withdrawals, including all growth, are tax-free.
• •2026 contribution limit — 401(k): $24,500, plus $8,000 catch-up at 50+ ($11,250 at ages 60-63). · Roth IRA: $7,500, plus $1,100 catch-up at 50+.
• •Income limits — 401(k): none. · Roth IRA: phases out at $153,000-$168,000 (single) and $242,000-$252,000 (married filing jointly) in 2026.
• •Employer match — 401(k): often yes, and it's extra money on top of your limit. · Roth IRA: never; there's no employer involved.
• •Investment choice — 401(k): the menu your plan chose, often 10-30 funds. · Roth IRA: open brokerage; nearly any fund, index, or stock.
• •Required withdrawals — 401(k): traditional balances have RMDs starting at age 73. · Roth IRA: no required withdrawals during your lifetime.
• •Early access — 401(k): generally locked until 59½; early withdrawals are taxed plus a 10% additional tax, with exceptions. · Roth IRA: your contributions (not earnings) can come out anytime, tax- and penalty-free.

The Match: Part of Your Pay You Have to Claim

An employer match only exists inside workplace plans — no IRA of any kind comes with one. A common formula is 50 cents or a dollar per dollar you contribute, up to some percentage of your salary. Stop and look at what that actually is: a 100% match on 4% of a $60,000 salary is $2,400 a year of compensation your employer has already budgeted for you, paid only if you contribute. It isn't a bonus or a perk — it's part of your pay that you have to claim, and no other account can offer a guaranteed instant return like it.

Two technical points keep the numbers straight. First, your employer's match does not count against your $24,500 deferral limit — that cap applies only to your own paycheck contributions. Match dollars instead count toward a separate overall ceiling on total additions to your account (your contributions plus all employer money), which is $72,000 for 2026. Second, missing the match isn't neutral: every year you contribute less than the match threshold, that slice of compensation simply never gets paid to you. That's why nearly every ordering framework, whatever it says next, starts in the same place.

The Widely Used Order: Match, Then Roth IRA, Then Back

1. 1

   Step 1: Contribute enough to your 401(k) to get the full match

   Whatever percentage your employer matches, contribute at least that much. This step outranks everything else because the match is an immediate, guaranteed addition to your savings that disappears if unclaimed — before any debate about tax rates even begins.

2. 2

   Step 2: Fund a Roth IRA next, if you're eligible

   With the match secured, many guides point the next dollars at a Roth IRA — up to the $7,500 limit for 2026. The reasons are flexibility and tax diversity: you pick your own investments on an open menu, your contributions stay reachable in a true emergency, qualified growth is never taxed, and you're building a pot of retirement money the IRS won't touch later.

3. 3

   Step 3: Go back to the 401(k) with anything left

   If you can save beyond the match plus $7,500, return to your 401(k), which has room all the way up to $24,500. At this stage you're choosing between pre-tax and Roth treatment (many plans now offer a Roth 401(k) option with no income limit) rather than between accounts.

4. 4

   Why this order, in one sentence

   Claim the guaranteed money first, buy flexibility and tax-free growth second, and use the big-capacity account for everything after that. This is widely used educational guidance, not personal advice — your income, plan quality, and tax bracket can reshuffle it, and a fee-only advisor or tax professional can pressure-test it against your specifics.

When Traditional Beats Roth — and Vice Versa

Strip away the branding and the real question isn't which account — it's which tax rate: yours today, or yours in retirement. A traditional 401(k) is a bet that your retirement tax rate will be lower than today's, so deferring makes sense. A Roth is the opposite bet — that today's rate is the cheapest tax you'll ever pay on this money. That's why traditional often appeals to high earners in their peak years who expect a quieter tax picture in retirement: skipping tax at a high bracket now and paying at a lower one later is straightforwardly a win if the bet lands.

Roth tends to win for people early in their careers — paying tax now at a modest rate to make decades of growth permanently tax-free — and for anyone who expects rates or their own income to be higher later. And since nobody actually knows their tax bracket in 2055, there's a boring, sturdy answer hiding here: holding both pre-tax and Roth money gives you options, letting you choose which pot to draw from year by year in retirement. The match-first order quietly delivers exactly that mix.

Getting Money Out: RMDs and the Flexibility Gap

Both account types are built for age 59½. Take money out of a traditional 401(k) or IRA before then and, per the IRS, the taxable amount is generally hit with a 10% additional tax on top of ordinary income tax — though a long list of exceptions exists, including disability, certain medical expenses, and separating from your employer at 55 or later. The Roth IRA is the outlier: because you already paid tax on your contributions, the IRS lets you withdraw those contributions — not the earnings — at any time, at any age, tax- and penalty-free. Earnings are the part that must wait: touching them tax-free requires the account to be five years old and you to be 59½ (the "5-year rule").

The other end of life has rules too. Traditional 401(k)s and traditional IRAs carry required minimum distributions — the IRS makes you start withdrawing, and paying tax, at age 73 under current rules, rising to age 75 for people born in 1960 or later (a SECURE 2.0 change that takes effect in 2033). A Roth IRA has no required withdrawals during your lifetime — the money can sit and compound untouched for as long as you live. And thanks to SECURE 2.0, Roth 401(k) balances joined that club starting in 2024: the IRS confirms designated Roth accounts in a 401(k) or 403(b) no longer require lifetime distributions either. If keeping control of your money late in life matters to you, Roth accounts are structurally better at it.

How to Actually Decide

Here's the decision compressed to its essentials. If your employer matches, the first move is settled — that's your own compensation on the table, and no tax-rate theory beats a guaranteed match. After that, the choice runs on two questions: do you value flexibility and tax-free growth enough to route dollars through a Roth IRA's smaller door, and do you honestly expect your tax rate in retirement to be higher or lower than it is today? Lower points traditional; higher, or "no idea," points Roth — and splitting between the two is a legitimate answer, not a cop-out.

What you shouldn't do is stall. The gap between funding something and funding the theoretically optimal thing is small; the gap between funding something and funding nothing is enormous, because the match forfeited and the compounding missed never come back. Get the match, open the Roth IRA if you're eligible, automate both, and revisit the mix once a year when the IRS publishes new limits. The order can be tuned later — the habit can't be backdated.
