“Which one should I do first — my 401(k) or a Roth IRA?”
This is one of the most common questions from beginner investors. The honest answer isn’t “one or the other” — it’s about order, and the order depends on a few specific things. This is the plain-English breakdown.
What a Roth IRA actually is
A Roth IRA is a retirement account you open yourself, at any brokerage (Fidelity, Schwab, Vanguard, etc.). You put money in that you’ve already paid tax on. Then it grows tax-free forever. When you take it out at retirement (after age 59½), you don’t pay a dime in tax — not on contributions, not on growth.
For 2026, the contribution limit is $7,500 a year ($8,600 if you’re 50+). You can withdraw your contributions (but not earnings) any time without penalty.
What a 401(k) actually is
A 401(k) is a retirement account offered through your employer. You contribute pre-tax dollars — meaning the money never hit your paycheck as taxable income. It grows tax-deferred. When you take it out at retirement, you pay ordinary income tax on every dollar.
For 2026, the contribution limit is $24,500 . If you’re 50 or older, you can contribute an additional $8,000 catch-up, for a total of $32,500. There is also a special higher catch-up for participants ages 60–63 in eligible plans: $11,250 instead of $8,000, for a total of $35,750. Most employer 401(k) plans will clarify which catch-up limit applies to you. The huge advantage: many employers match part of your contribution — usually 3–6% of your salary. That match is free money.
Side-by-side: Roth IRA vs 401(k)
| Feature | Roth IRA | 401(k) |
|---|---|---|
| Tax on contribution | Paid now | Deferred |
| Tax on retirement withdrawal | $0 | Ordinary income tax |
| 2026 contribution limit | $7,500 | $24,500 |
| Employer match available? | No | Often (free money) |
| Investment choices | Anything at your broker | Plan-limited menu |
| Income limit to contribute? | Yes — phase-out $153K–$168K (single) / $242K–$252K (married) in 2026 | No |
When Roth wins
- You’re in a lower tax bracket now than you expect at retirement. This is true for most people under 35 making under ~$100K. Pay the tax now while it’s low.
- You want tax-free growth and flexibility. Roth contributions can be withdrawn any time without penalty (just not the earnings). Useful in emergencies.
- You want investment choice. Inside a Roth IRA you can buy any ETF, index fund, or individual stock. Inside a 401(k) you’re stuck with your plan’s menu.
When 401(k) wins
- Your employer matches. Always, always, always contribute enough to get the full match first. It’s a 50–100% instant return — beats every other investment, including paying off most debt.
- You’re in a high tax bracket now. If you’re earning $150K+, the immediate tax deduction from a traditional 401(k) is worth more than the future tax-free growth of a Roth.
- You can save more than $7,500/year. Roth IRAs cap at $7,500. 401(k)s let you put away $24,500.
The correct order to fund them
This is the playbook for most working-class and middle-class beginners:
- Contribute to your 401(k) up to the full employer match. If your company matches 5% of salary, contribute at least 5%. Stop nothing else until you’ve captured the full match — it’s free money.
- Max out a Roth IRA at $7,500/year. Open one at Fidelity or Schwab (no fees). Invest in a total US stock market index fund (VTI, FZROX, or similar). Automate monthly contributions of about $625/month.
- If you are 50 or older, the $8,600 catch-up limit equals about $717/month.
- Go back to your 401(k) and max it out at $24,500/year (if you can afford to).
- Then a regular taxable brokerage account for anything beyond that.
For most beginners earning under $100K, you’ll never get past steps 1 and 2 — and that’s fine. Those two alone, maxed out over 30 years, build serious wealth.
Common beginner mistakes
- Skipping the 401(k) match. Even if you “don’t trust the stock market,” at least capture the match. It’s literally free salary.
- Putting Roth IRA money in cash or a CD. The tax advantage only works if the money grows. Invest it. Index funds.
- Not opening a Roth IRA because “I already have a 401(k).” You can have both. Most people should.
- Choosing Traditional IRA instead of Roth without doing the math. For most under-35 working folks earning under $100K, Roth wins on lifetime tax math. Run the numbers before defaulting to Traditional.

Should I max out my 401k or Roth IRA first in 2026?
If your employer offers a 401k match, contribute at least enough to get the full match first — that’s free money. After that, many financial advisors recommend maxing out a Roth IRA if you qualify, then returning to max your 401k.
Can I contribute to both a Roth IRA and a 401k?
Yes. You can contribute to both in the same year, as long as you meet the income limits for the Roth IRA. In 2026, the Roth IRA contribution limit is $7,500 ($8,600 if you’re 50+) and the 401k limit is $24,500.
What is the Roth IRA income limit in 2026?
In 2026, you can contribute the full amount to a Roth IRA if your MAGI is under $153,000 (single) or $242,000 (married filing jointly). The contribution phases out above those levels and is eliminated at $168,000 (single) or $252,000 (married).
Which is better for someone in a low tax bracket?
If you’re in a low tax bracket now, a Roth IRA is usually better. You pay taxes on contributions now (at your low rate) and withdraw everything tax-free in retirement. If you expect to be in a higher bracket later, the Roth advantage grows even more.
Is a Roth IRA or 401k better for a 30-year-old?
Most 30-year-olds benefit from both. A Roth IRA offers flexibility — you can withdraw contributions (not earnings) penalty-free at any time. A 401k with an employer match is essentially a 50–100% instant return. Use both if possible.
