Both accounts work the same way at their core. You contribute after-tax dollars, the money grows tax-free, and qualified withdrawals in retirement are not taxed. The differences are in how much you can put in, what you can invest in, and how easily you can reach the money.

The core differences
The table below is where nearly every real decision gets made. Focus on limits, income eligibility, and investment options.
- Contribution limit: $23,500 for the Roth 401(k) versus $7,000 for the Roth IRA in 2025.
- Catch-up at 50+: $7,500 extra in the 401(k), $1,000 extra in the IRA.
- Income limits: none for the Roth 401(k); Roth IRA eligibility phases out for higher earners.
- Investments: a 401(k) offers a fixed menu; an IRA opens the entire brokerage universe.
- Early access: Roth IRA contributions can be withdrawn anytime tax- and penalty-free.
- Loans: available from many 401(k) plans, never from an IRA.
When the Roth 401(k) wins
The 401(k) is the better primary account for high earners and for anyone who saves best when the money never touches their checking account.
- Your income is above the Roth IRA phase-out, making direct IRA contributions unavailable.
- You want to save more than $7,000 a year in Roth dollars.
- Payroll deduction keeps you consistent without any monthly effort.
- Your plan offers institutional-class index funds with very low expense ratios.
When the Roth IRA wins
The IRA is the better account when your workplace plan has poor fund options or high administrative fees, and when flexibility matters to you.
- You can hold any ETF, index fund, or individual stock rather than a limited menu.
- Contributions (not earnings) come out anytime without tax or penalty.
- No required minimum distributions during your lifetime.
- The account stays with you permanently, independent of any employer.
A practical funding order
For most households, this sequence captures the free money first, then the flexibility, then the raw contribution room.
- 1
Contribute to the 401(k) up to the full employer match — this is an immediate guaranteed return.
- 2
Fund a health savings account if you have a qualifying high-deductible plan.
- 3
Max the Roth IRA at $7,000 for the low fees and broad investment selection.
- 4
Return to the 401(k) and increase contributions toward the annual limit.
- 5
If you exceed the Roth IRA income limit, use a backdoor Roth IRA instead.
