Roth IRA vs. 401(k): Which should I prioritize?

For most people, the answer is both — in a specific order: contribute to your 401(k) up to the full employer match first (that match is part of your compensation), then fund a Roth IRA up to the annual limit, then return to your 401(k) if you have more to save. The Roth IRA vs. 401(k) choice is fundamentally a tax-timing trade-off: 401(k) contributions are usually pre-tax (you pay tax at withdrawal); Roth IRA contributions are after-tax (qualified withdrawals are tax-free). **ClearValue Lending is not a Registered Investment Advisor; this is financial education, not personalized investment advice.**

The Roth IRA and 401(k) are the two most common retirement accounts, and they're designed to work together — not compete. Brian's video on retiring faster walks through the tax-treatment math behind each; this page lays out the structural differences and the prioritization framework most financial planners use.

What each account actually is

401(k): An employer-sponsored retirement plan defined by IRS Section 401(k). You contribute through payroll deduction. Traditional 401(k) contributions are pre-tax — they reduce your taxable income now but are taxed as ordinary income at withdrawal. Many employers match a percentage of what you contribute.
Roth IRA: An Individual Retirement Account you open yourself at a bank or brokerage. Contributions are made with after-tax dollars — no immediate tax deduction. Qualified withdrawals in retirement are tax-free, including all investment growth. Governed by IRS Publication 590-A and 590-B.

The employer match: why 401(k) usually comes first

If your employer offers a 401(k) match, that match is part of your total compensation — not contributing enough to capture it is effectively declining part of your salary. A common match formula: 50% of your contributions up to 6% of your salary. On a $70,000 salary, contributing 6% ($4,200/year) earns $2,100 in employer contributions — an immediate 50% return before any investment gains. The Roth IRA offers no equivalent.

According to the DOL's EBSA 401(k) plan resources, employers are permitted (but not required) to match employee contributions, and must disclose match formulas and vesting schedules in the plan's Summary Plan Description.

Contribution limits: 401(k) is much higher

The 2025 limits illustrate a significant gap. The 401(k) employee elective deferral limit is $23,500 per year ($31,000 if age 50 or older). The Roth IRA limit is $7,000 per year ($8,000 if age 50 or older). These are separate limits — you can max both in the same year. However, the Roth IRA has income phase-outs the 401(k) does not: for 2025, contributions phase out for single filers with modified AGI between $150,000 and $165,000, and for married filing jointly between $236,000 and $246,000.

The tax trade-off: which bet are you making?

A traditional (pre-tax) 401(k) is a bet that your current marginal tax rate is higher than your rate in retirement. You reduce taxable income now and pay ordinary income tax at withdrawal. A Roth IRA is the reverse: you pay tax now at your current rate and owe nothing on qualified distributions later. Neither is universally better.

Higher earners in peak years often benefit more from the traditional pre-tax 401(k) — the deduction is worth more when you're in a high bracket now and expect a lower bracket in retirement.
Younger workers or lower-income earners often benefit more from the Roth IRA — paying tax now at a lower rate and locking in tax-free growth for decades.
Roth 401(k) option: If your employer offers a Roth 401(k), you get the higher contribution limit with after-tax treatment — useful if you're above the Roth IRA income phase-out or want more Roth-sheltered space.

The common prioritization framework

401(k) up to the full employer match — capture all employer contributions first.
Roth IRA up to the annual limit — broader investment flexibility, tax-free growth, no required minimum distributions (RMDs) during the owner's lifetime.
401(k) beyond the match — use the higher limit to maximize tax-advantaged space.
Taxable brokerage (if more remains) — no contribution limits, but investment gains are taxable.

This is a general heuristic. Your income, tax bracket, expected retirement income, and employer plan options all affect which order makes sense. A Registered Investment Advisor or CPA can model the trade-off for your specific numbers.

Self-employed angle: Solo 401(k) and SEP-IRA

If you're self-employed, a Solo 401(k) (one-participant 401(k)) lets you contribute as both employer and employee — up to $70,000 in 2025 at higher income levels. A SEP-IRA is another high-ceiling employer-side option. In either case, a Roth IRA can still sit on top, subject to the same income limits. The prioritization logic stays similar: maximize tax-advantaged space first, then add Roth IRA for its unique benefits (no lifetime RMDs, tax-free qualified withdrawals).

Current IRS figures (2025)

The 401(k) employee elective deferral limit for 2025 is $23,500 ($31,000 for those age 50 or older). The combined employer + employee limit is $70,000 ($77,500 with catch-up). — IRS — Retirement Topics: 401(k) and Profit-Sharing Plan Contribution Limits
The IRA contribution limit for 2025 is $7,000 ($8,000 if age 50 or older). Roth IRA contributions phase out for single filers with modified AGI between $150,000 and $165,000, and for married filing jointly between $236,000 and $246,000. — IRS — Roth IRAs
Qualified distributions from a Roth IRA are tax-free and penalty-free if the account has been open at least five years and the owner is age 59½ or older. Contributions (not earnings) can be withdrawn at any time tax-free and penalty-free. — IRS Publication 590-B — Distributions from Individual Retirement Arrangements
Employers sponsoring 401(k) plans must provide participants a Summary Plan Description disclosing contribution limits, matching formulas, and vesting schedules.

Key takeaways

Most people benefit from using both — the common order is: 401(k) to the employer match → Roth IRA → 401(k) beyond the match.
The employer match is part of your compensation. Not capturing it is leaving part of your salary on the table.
401(k) limit ($23,500 for 2025) is more than 3× the Roth IRA limit ($7,000). Roth IRA has income phase-outs; 401(k) does not.
Traditional 401(k) is a bet your current tax rate is higher than your future retirement rate. Roth IRA is the reverse.
Self-employed workers can substitute a Solo 401(k) or SEP-IRA for the employer-plan slot, then layer a Roth IRA on top.
