🏖️ Roth IRA vs 401(k): Which Should You Fund First?
📊 Side-by-Side Comparison
| Aspect | Roth IRA | 401(k) |
|---|---|---|
| Tax Treatment | After-tax in, tax-free growth and withdrawals. | Usually pre-tax in, taxed on withdrawal (Roth 401k exists). |
| 2026 Contribution Limit | ~$7,000 ($8,000 if 50+). | ~$23,000+ ($30,500+ if 50+) — much higher. |
| Employer Match | None. | Often 50-100% up to a percentage of pay — free money. |
| Income Limits | Phases out at higher incomes. | No income limit to contribute. |
| Investment Choices | Wide open (any broker). | Limited to the plan's fund menu. |
| Early Withdrawal | Contributions withdrawable anytime, penalty-free. | Generally penalized before 59½. |
| Bottom Line | Best for tax-free growth and flexibility. | Best for the match and high contribution room. |
What is Roth IRA?
A Roth IRA is an individual retirement account you open yourself at any brokerage. You contribute after-tax dollars — no deduction today — but your investments grow completely tax-free, and qualified withdrawals in retirement are tax-free too. You also get a wide universe of investment choices and the unique flexibility to withdraw your contributions (not earnings) at any time without taxes or penalties.
Roth IRAs shine when you expect to be in the same or a higher tax bracket in retirement, when you want tax diversification, or when you value flexibility. The catches: the annual contribution limit is much lower than a 401(k) (~$7,000 in 2026), and high earners are phased out of direct contributions (though a backdoor Roth can work around that). It's the ideal second account to fund after capturing your employer match.

What is 401(k)?
A 401(k) is an employer-sponsored retirement plan funded directly from your paycheck, usually with pre-tax dollars that lower your taxable income today. The standout feature is the employer match: many employers contribute 50-100% of your contributions up to a percentage of your salary. That match is an immediate, guaranteed return that no other account offers — which is why funding the 401(k) up to the full match always comes first.
401(k)s also have a much higher contribution limit (~$23,000+ in 2026) and no income limit to participate, making them the workhorse for high earners and aggressive savers. The trade-offs are a limited menu of investment funds, potentially higher fees, and taxes due on withdrawals (unless it's a Roth 401(k)). Many plans now offer a Roth 401(k) option, combining the high limit with tax-free growth.

🔑 Key Differences
- Match: Only the 401(k) offers an employer match — always capture it first.
- Taxes: Roth IRA is tax-free later; traditional 401(k) is tax-deferred (taxed later).
- Limits: 401(k) lets you contribute far more per year.
- Choices: Roth IRA has unlimited investment options; 401(k) is a fixed menu.
- Flexibility: Roth contributions are accessible anytime; 401(k) is locked until 59½.
- Income limits: Roth IRA phases out for high earners; 401(k) does not.
- Decision driver: Match first, then Roth for flexibility, then 401(k) for the higher ceiling.

💡 Real-World Examples
Example 1: Match First, Always
Your employer matches 100% of the first 4% of pay. On a $60,000 salary, contributing $2,400 earns another $2,400 free — a 100% instant return. No Roth IRA can beat that, so the 401(k) match comes first.
Example 2: The Optimal Order
After the match, you max a $7,000 Roth IRA for tax-free, flexible growth, then return to the 401(k) to push toward its ~$23,000 limit. This sequence captures free money, tax diversification, and maximum room.
Example 3: High Earner
A $200,000 earner is phased out of a direct Roth IRA. They max the 401(k) ($23,000) for the tax break and high limit, then use a backdoor Roth IRA to still get tax-free growth.
❓ Frequently Asked Questions
Should I contribute to a Roth IRA or 401(k) first?
Fund your 401(k) up to the full employer match first (it's free money), then max a Roth IRA, then return to the 401(k). If there's no match, many savers start with the Roth IRA for flexibility.
Can I have both a Roth IRA and a 401(k)?
Yes — they're separate accounts with separate limits, and using both is often the optimal strategy for tax diversification.
Is a Roth or traditional 401(k) better?
Roth (tax-free later) suits those expecting higher future taxes; traditional (tax break now) suits those in a high current bracket. Splitting between them hedges your bet.
What is a backdoor Roth IRA?
A legal method for high earners to fund a Roth IRA by contributing to a traditional IRA and converting it, sidestepping the income limit. Use our [retirement calculator](/calculators/retirement-calculator.html) to project growth.
How much should I contribute to retirement?
Aim for at least 15% of income including any match. Start with the match, then build toward maxing tax-advantaged accounts as your budget allows.
