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

The Roth IRA and the 401(k) get compared constantly, but they are not really competing products. They are different tools that most people end up using together. The question is usually what order to fund them in, and there is a fairly clear answer.

The structural differences

A 401(k) is offered through an employer, has much higher contribution limits, and may include an employer match, which is essentially free money added on top of personal contributions. A Roth IRA is opened on your own at any brokerage and has lower contribution limits. In exchange, it offers investment choice a workplace 401(k) menu usually cannot match. It also has income limits that can restrict or block high earners from contributing directly.

	401(k)	Roth IRA
2026 contribution limit	$24,500 (per IRS)	$7,500
Employer match	Often, and it's free money	Never
Investment choice	Plan's menu only	Anything the brokerage sells
Income limits	None	Phases out from $153,000 (single) / $242,000 (joint)
Tax treatment	Usually pre-tax now, taxed later	Taxed now, tax-free forever

A traditional 401(k) is pre-tax by default and a Roth IRA is after-tax by default, though Roth 401(k) options are increasingly common too. See 401(k) Basics and Roth IRA vs. Traditional IRA for the deeper mechanics of each.

The order that maximizes both

1. Contribute to the 401(k) up to the full employer match, if one exists. This is a guaranteed, immediate return that neither a Roth IRA nor any investment can match, so turning down free matching money to prioritize anything else rarely makes sense.
2. Max out a Roth IRA next, if your income allows contributing to one. The broader investment selection and the tax-free growth make this a strong second stop, especially for anyone early in their career who expects a similar or higher tax bracket later.
3. Return to the 401(k) and contribute beyond the match, up to the annual limit, if there is still money left to save after steps 1 and 2.

Why this order, and not the reverse

Skipping the match to fund a Roth IRA first means giving up free money to get broader investment choice. That benefit is real, and it is smaller than an immediate 50-100% guaranteed return on contributed dollars. Once the match is secured, the Roth IRA's flexibility and typically lower fund fees make it the better next stop, before piling more into a 401(k) that may have a limited, higher-fee fund menu.

When the order changes

High earners who are blocked from contributing to a Roth IRA directly may use a backdoor Roth conversion instead, which is worth discussing with a tax professional given the complexity. Or they may simply prioritize maxing the 401(k), since the Roth IRA path is closed at their income level. Someone with a genuinely excellent 401(k) plan, meaning very low fees and strong fund options, might reasonably max it out before or alongside a Roth IRA. The usual case for prioritizing the Roth IRA is weaker when the 401(k) menu is already good.

The version that matters most

Perfecting the exact order matters far less than actually contributing consistently to something. The gap between someone who follows this order precisely and someone who just contributes steadily to either account is small, compared to the gap between either of them and someone who is not contributing at all.
