Should I max out Roth IRA or 401(k) first?

Short answer: contribute enough to your 401(k) to capture the full employer match first, then fund a Roth IRA, then go back and add more to the 401(k) if you still have savings left. For 2026, that means grabbing the match, then putting up to $7,500 into a Roth IRA (or $8,600 if you are 50 or older), then returning to the 401(k) where the limit is $24,500.

This ordering is not a law. It is a widely used heuristic, and it holds up well for most people in their working years because it captures free money first and tax diversification second. But your tax bracket, your income, and your plan's quality can all change the right answer. The sections below walk through how to think it through rather than just handing you the rule.

Step one: always take the full 401(k) match

An employer match is an immediate, guaranteed return on your contribution. If your employer matches 50 percent of your contributions up to 6 percent of your salary, that is a 50 percent instant return on the matched portion. Nothing else in personal finance competes with that.

This is why the match comes first, before any debate about Roth versus traditional or IRA versus 401(k). Failing to capture the full match is leaving part of your compensation on the table. It does not matter whether you prefer Roth or traditional accounts. Contribute at least enough to get the full match, whatever the account type.

Check your plan's vesting schedule while you are at it. Some employers require you to stay a few years before the matched money is fully yours. The match is still worth capturing, but the vesting timeline is worth knowing.

Step two: why the Roth IRA usually comes next

Once the match is secured, the next dollars often work harder in a Roth IRA. There are a few reasons.

First, control. A 401(k) limits you to the investment menu your employer chose, which is sometimes excellent and sometimes mediocre. A Roth IRA at any major brokerage gives you access to nearly the entire market, including the lowest-cost index funds available, with no one else's restrictions.

Second, flexibility. Roth IRA contributions (the money you put in, not the earnings) can be withdrawn at any time without taxes or penalties. This is not a feature to plan around, but it makes the account less rigid than a 401(k), where early withdrawals generally trigger penalties.

Third, tax diversification. If your 401(k) contributions are traditional (pre-tax), funding a Roth IRA means you are building a pool of money that will be tax-free in retirement alongside a pool that will be taxed. That mix gives you options later, when you get to choose which account to draw from each year to manage your tax bill.

For 2026, the IRA contribution limit is $7,500 if you are under 50, or $8,600 with the catch-up contribution if you are 50 or older. Remember this is a combined limit across traditional and Roth IRAs, not per account.

The income limits that can change the plan

Roth IRAs have income caps that traditional 401(k)s do not. For 2026, single filers with modified adjusted gross income below $153,000 can make the full Roth contribution, with a phase-out up to $168,000. Married couples filing jointly get the full contribution below $242,000, phasing out by $252,000. Above those levels, direct Roth IRA contributions are not allowed.

If your income is above the phase-out range, the standard advice shifts. Options include making a nondeductible traditional IRA contribution and converting it to Roth (the "backdoor Roth" strategy), or simply directing everything into the 401(k). The backdoor route has tax nuances, especially if you already hold pre-tax IRA balances, so it is worth reading carefully or talking to a tax professional before attempting it.

This is also the one situation where "max the Roth first" advice can mislead. If you cannot contribute to a Roth directly, the 401(k) is not a consolation prize. It is the main account.

When maxing the 401(k) first makes more sense

There are legitimate cases for skipping the Roth IRA step and pouring everything into the 401(k).

High earners in their peak earning years often benefit more from the immediate tax deduction of traditional 401(k) contributions than from Roth contributions. If you are in a high bracket now and expect to be in a lower one in retirement, deferring taxes usually wins. The math favors paying taxes later at the lower rate.

People with excellent 401(k) plans sometimes find the Roth IRA's advantages are mostly theoretical. If your plan offers low-cost index funds and good service, the difference between investing there and in an IRA is small. Simplicity has value, and one account is simpler than two.

There is also the saver's credit and other situations where traditional contributions reduce your current taxable income in ways that unlock other benefits. These are edge cases, but they exist, and they are another reason the decision deserves a moment of real thought rather than blind rule-following.

The case for Roth contributions inside the 401(k)

Many 401(k) plans now offer a Roth 401(k) option alongside the traditional one. This changes the framing a bit. If you prefer Roth treatment but cannot use a Roth IRA because of income limits, or if you simply want to keep things in one place, the Roth 401(k) lets you get Roth tax treatment with the 401(k)'s much higher contribution limit of $24,500 for 2026.

The choice between Roth and traditional inside the 401(k) comes down to the same question as always: will your tax rate be higher now or in retirement? Young workers early in their careers, when incomes and brackets tend to be lowest, often favor Roth. Peak earners often favor traditional. There is no universally correct answer, and splitting contributions between the two is a reasonable middle path that many people overlook.

One detail worth knowing: employer matching contributions always go into the traditional (pre-tax) side of the 401(k), even if your own contributions are Roth. Your match dollars will be taxed in retirement regardless.

What the numbers look like at each stage

It helps to see the order of operations as a funding waterfall. Here is how a typical year plays out for someone earning a salary with a standard match.

First, contribute to the 401(k) up to the match. If you earn $80,000 and your employer matches 50 percent up to 6 percent of salary, you contribute $4,800 and your employer adds $2,400. That $2,400 is a return no investment can promise.

Second, fund the Roth IRA up to the $7,500 limit for 2026. This is $625 a month if you automate it, which is the easiest way to make sure it happens.

Third, if you still have savings capacity, increase 401(k) contributions toward the $24,500 limit. The gap between the match-only contribution and the full limit is large, and closing it is what separates adequate retirement saving from genuinely comfortable saving.

If you are self-employed or your employer offers no match, the waterfall simplifies: the Roth IRA's flexibility and control often make it the first stop, with the 401(k) equivalent (a Solo 401(k) or SEP IRA) handling the rest.

The mistake to avoid

The most common mistake is not the order of accounts. It is choosing the accounts and then investing badly inside them, or worse, not investing at all. A meaningful number of 401(k) participants leave their contributions sitting in a default money market or stable value fund for years, earning a fraction of what a simple target-date or index fund would return.

Whichever account you fund, the next step is the same: invest the money in something appropriate, usually a low-cost diversified fund, and leave it alone. The account type determines the tax treatment. The investments determine the growth. Both matter, but the second one matters more than most people realize.

Another quiet mistake is treating the contribution limits as targets to hit eventually rather than as amounts to automate now. If maxing the Roth IRA feels out of reach, contribute what you can monthly. Partial funding beats waiting for a perfect month that never comes.

A calm way to think about it

The match-first, Roth-second, 401(k)-third order is good default advice because it is simple and right for most people most of the time. But defaults are starting points, not verdicts. Your tax situation, your plan quality, and your income level all deserve a vote.

The deeper principle is this: save consistently, capture every dollar of free money, diversify your tax treatment, and keep fees low. Do those four things in whichever account order fits your life, and the exact sequence of funding will matter far less than the fact that you kept funding them year after year.

Review the order once a year, automate the contributions, and then stop thinking about it. Retirement saving works best as a system you set up deliberately and then mostly ignore.
