Roth IRA vs. 401(k): Which Is Better?
A 401(k) comes through your job and has a much higher limit; a Roth IRA you open yourself and gives tax-free money in retirement. Most people can — and often should — use both. Here’s the order to fund them.
By Bogdan · Updated
A 401(k) and a Roth IRA are the two most common retirement accounts in the US. They aren’t really rivals: they have separate limits, and many people use both. The real question is which to fund first.
Explain it like I’m 5
Imagine two treasure chests for when you’re old.
- The 401(k) chest comes from your job. It’s huge, and sometimes your boss adds free coins every time you put some in (the match). But you pay tax when you take coins out later (unless it’s a Roth 401(k)).
- The Roth IRA chest you get yourself. It’s smaller, but you pay the tax before putting coins in — and then everything that grows inside is tax-free forever when you’re old.
The smart trick: grab the boss’s free coins first, then fill the Roth chest, then go back to the big chest.

Side by side (2026)
| 401(k) | Roth IRA | |
|---|---|---|
| Who offers it | Your employer | You open it (at a broker or bank) |
| 2026 contribution limit | $24,500 (+$8,000 at 50+, or +$11,250 at 60–63) | $7,500 (+$1,100 at 50+) |
| Income limit | None | Phases out at $153,000–$168,000 single, $242,000–$252,000 married filing jointly |
| Tax break | Traditional: now. Roth 401(k): later | Later — qualified withdrawals are tax-free |
| Employer match | Often | Never |
| Investment choices | Limited to the plan’s menu | Almost anything |
| Early access | Limited; loans may be available | Contributions can come out any time, tax- and penalty-free |
| Required withdrawals | Traditional: yes, from 73 or 75. Roth 401(k): none since 2024 | None during your lifetime |
The usual order to save
- 401(k) up to the full employer match. A 50% or 100% match is an instant return you can’t get anywhere else.
- Pay off high-interest debt and build an emergency fund.
- Roth IRA up to the limit (if your income allows). Tax-free growth, better investment choices, and flexible access to contributions.
- Back to the 401(k) — up to its limit.
- Taxable brokerage account, HSA (if you have one) or other goals.
Many people put the HSA at step 3 or 4 too, because it can be tax-free going in and coming out for medical costs.
Traditional or Roth inside the 401(k)?
The same logic as Roth vs. traditional IRA applies:
- Lower tax bracket now than you expect in retirement → lean Roth.
- Higher bracket now → lean traditional and take the deduction.
- Not sure → split between them, or use traditional in the 401(k) and Roth in the IRA for a mix.
Note: from 2026, employees who earned more than a set amount in FICA wages the year before must make their 401(k) catch-up contributions as Roth.
Common mistakes
- Not contributing enough to get the full match — it’s part of your pay.
- Thinking a 401(k) blocks a Roth IRA. It doesn’t; only income does.
- Leaving 401(k) money in the default cash option. Check that contributions are actually invested.
- Cashing out a 401(k) when changing jobs instead of rolling it over.
Frequently asked questions
Is a Roth IRA or a 401(k) better?
It depends, but the best answer is usually both. Get any employer match in your 401(k) first, since it’s free money. Then a Roth IRA is often a great next step for its tax-free withdrawals and investment choice, before going back to the 401(k) for more.
How much can I contribute to a 401(k) and Roth IRA in 2026?
401(k): $24,500, plus an $8,000 catch-up at 50 or older (or $11,250 at ages 60–63). Roth IRA: $7,500, plus $1,100 at 50 or older — and Roth IRA contributions phase out at higher incomes. The two limits are separate, so you can contribute to both.
Can I have a 401(k) and a Roth IRA at the same time?
Yes. Having a 401(k) at work doesn’t stop you contributing to a Roth IRA. The only limit on the Roth IRA is your income (and earning at least as much as you contribute).
What is a Roth 401(k)?
A 401(k) where contributions go in after tax and qualified withdrawals come out tax-free — like a Roth IRA, but with the 401(k)’s higher limit and no income limit. Many employers offer both traditional and Roth 401(k) options.
What if I earn too much for a Roth IRA?
You can still use a 401(k) (traditional or Roth), and you may be able to use a backdoor Roth IRA: a non-deductible traditional IRA contribution that’s converted to a Roth.
