Both grow tax-free, but getting there works differently. Here's how 2026 contribution and income limits and withdrawal rules compare, plus how to decide which account to fund first.
Both a Roth 401(k) and a Roth IRA get you to the same place: tax-free withdrawals in retirement. How you get there is where they diverge: who can contribute, how much and what happens if you need the money early.
Here's how the two compare under current 2026 rules, and which one is worth funding first.
A Roth 401(k) is a designated Roth account offered within an employer-sponsored 401(k), 403(b) or governmental 457(b) plan, with separate accounting for contributions and earnings.
A 401(k), 403(b) or governmental 457(b) plan may permit some or all elective deferrals to be designated as Roth contributions, but the employer must choose to offer this feature.
Contributions come out of your paycheck through payroll deduction, same as a regular 401(k), except the money is after-tax. It's already included in your gross income for the year, unlike pretax deferrals, which is the trade-off that buys you tax-free withdrawals later.
Employer matching used to be simple: it always landed in a pretax account, regardless of whether your own contributions were Roth. That's no longer the only option.
Under SECURE 2.0, a plan may allow employees to designate certain matching or nonelective contributions as Roth, but only if the plan offers this feature, the contribution is fully vested and the employee's election is made no later than allocation and is irrevocable.
A matching or nonelective contribution designated as Roth under SECURE 2.0 is included in the employee's gross income for the taxable year in which it is allocated.
Features like loans and in-service withdrawals aren't guaranteed; a plan sponsor can choose to skip them entirely.
Check your employer's summary plan description to see what your specific plan allows.
A Roth IRA is an individual retirement account that an investor can open on their own through a brokerage or other IRA provider, independent of any employer. As it is not tied to a workplace plan, you set it up and manage it yourself.
Roth IRA contributions are made with after-tax dollars and are not tax-deductible. This after-tax treatment is what can enable tax-free qualified withdrawals in retirement, provided certain conditions are met.
To contribute directly, a taxpayer must have taxable compensation for the year, and direct Roth IRA contributions cannot exceed the applicable annual or compensation limit. Direct contribution eligibility is also subject to annual income thresholds, which we cover below.
What you can actually invest in depends entirely on the provider. Mutual funds are close to universal, but stocks, ETFs, bonds and crypto aren't guaranteed at every provider, so it's worth checking what's supported before you open an account.
Both accounts give you the same tax-free growth potential, as described above, but the employer-sponsored versus self-directed split changes almost everything else: contribution limits, income eligibility, employer match and how easily you can get at your money early.
The table below summarizes the core differences at a glance.
For a deeper look at how withdrawals interact with taxes, this retirement tax rules guide would be handy knowledge.
Feature | Roth 401(k) | Roth IRA |
Employer involvement | Employer-sponsored plan feature | Opened independently through a provider |
2026 contribution limit | $24,500 employee deferral | $7,500 combined across IRAs |
Income restrictions | No income limit on participation | MAGI phase-outs apply |
Employer match | May be Roth-designated if the plan allows | Not applicable |
Investment options | Depend on the plan's menu | Depend on the provider |
Early withdrawal | Nonqualified amounts taxed pro rata | Contributions come out first |
Loans | Optional plan feature, not guaranteed | Generally not available |
Lifetime RMDs | Eliminated under SECURE 2.0 | None for the owner |
On early access, the difference is notable. A nonqualified Roth 401(k) distribution is allocated pro rata between contributions (basis) and earnings; the earnings portion can be taxable and may be subject to an early-distribution tax.
By contrast, Roth IRA distributions are treated as coming first from regular contributions, then from conversion or rollover contributions and lastly, from earnings.
As of 2026, the IRS set the employee elective-deferral limit for 401(k) plans at $24,500, up from $23,500 in 2025. This limit applies to designated Roth and pretax deferrals combined.
Catch-up contributions add more room for older savers. The 2026 catch-up rules include:
One 2026 change specifically affects Roth 401(k)s: if your prior-year wages exceeded $150,000, your catch-up contributions must now be made on a Roth basis, even if the rest of your 401(k) contributions are pretax. High earners who assumed they'd keep deferring catch-up dollars pretax no longer have that choice.
For IRAs, the 2026 combined annual contribution limit for traditional and Roth IRAs is $7,500. This limit is shared across both account types, not $7,500 each. IRA owners age 50 and older can contribute an additional $1,100 catch-up amount, for a potential total of $8,600.
Income eligibility is where these accounts diverge sharply. The IRS does not impose an income limitation on participation in a designated Roth 401(k) account, unlike the MAGI-based phase-outs that apply to direct Roth IRA contributions. In other words, high earners can generally still contribute to a workplace Roth 401(k).
For direct Roth IRA contributions in 2026, Modified Adjusted Gross Income (MAGI) thresholds apply:
Above the top of each range, direct contributions are not allowed. High earners who exceed these limits sometimes explore a strategy commonly called a Backdoor Roth IRA, though the mechanics are beyond this guide's scope.
Both accounts reward patience through what the IRS calls a qualified distribution. For a Roth 401(k), two boxes need to be checked: a five-taxable-year participation period (the clock starts on January 1 of the year you first made Roth contributions to the plan), plus a qualifying event, meaning you've turned 59½ or the distribution is due to death or disability.
The five-year rule and age 59½ threshold determine whether earnings come out tax-free. Where the accounts really differ is early access to contributions.
A return of an individual's regular Roth IRA contributions is not included in gross income and, under the ordering rules, is generally distributed before earnings. This gives Roth IRAs notable flexibility for reaching original contributions. A Roth 401(k), by contrast, treats a nonqualified distribution pro rata between contributions and earnings, so part of an early withdrawal can be taxable.
SECURE 2.0 brought an important alignment. Section 325 eliminated the pre-death (lifetime) required minimum distribution requirement for designated Roth accounts in employer plans, effective for taxable years beginning after December 31, 2023. This brought Roth 401(k)s into line with Roth IRAs, whose owners have never had a lifetime required minimum distribution (RMD) obligation.
It’s common for savers to use a simple approach as a starting point. It's a general framework, not personalized advice, so weigh it against your own situation:
None of this is an ‘either-or’ choice. You're free to fund both a Roth IRA and a workplace Roth 401(k) in the same year, each subject to its own limits, with your IRA contribution still capped by the MAGI phase-outs above.
Leaving a job doesn't mean losing your old 401(k). The IRS gives you four options:
That last one can be costly: withdrawing can trigger taxes and penalties that rolling over avoids entirely.
A direct rollover keeps things simple: the plan administrator sends your balance straight to the new account, often by a check made payable to it, with no taxes withheld along the way. Roth 401(k) balances can generally roll into another designated Roth account or into a Roth IRA.
One option for consolidating former-employer funds is a Crypto.com IRA, a way to bring stock and retirement trading together in a single account.
Crypto.com IRA services, including Traditional and Roth IRAs, are offered to eligible US users only through its affiliate Foris Capital US LLC. It's a mixed-asset retirement account, stocks and crypto in one tax-advantaged wrapper, with zero fees to open.
There's also a match on qualifying transfers or 401(k) rollovers: no dollar cap on the total, though the rate depends on your tier, Basic at 1%, Plus and Pro at 2%, subject to program terms.
Is a Roth 401(k) the same as a Roth IRA?
No. A Roth 401(k) is a designated Roth account within an employer-sponsored plan, while a Roth IRA is an individual account opened independently. They also differ in contribution limits, with a 2026 employee deferral limit of $24,500 for a 401(k) versus a $7,500 combined IRA limit, and in income rules.
Can I have both a Roth 401(k) and a Roth IRA at the same time?
Yes. An eligible saver can contribute to both a Roth IRA and a workplace 401(k) in the same year, subject to each account's own eligibility rules and annual contribution limits. Your Roth IRA contributions remain subject to MAGI phase-outs.
What is the main difference between a Roth IRA and a Roth 401(k)?
The main differences involve contribution limits, income eligibility, employer match availability, and investment selection. Roth IRAs face MAGI phase-outs on direct contributions, while Roth 401(k) participation has no income limit. Under SECURE 2.0, a plan may also allow employer matches to be Roth-designated if it offers the feature.
Do Roth 401(k)s require minimum distributions in retirement?
No longer during the owner's lifetime. SECURE 2.0 Section 325 eliminated the pre-death (lifetime) required minimum distribution requirement for designated Roth accounts in employer plans, effective for taxable years beginning after December 31, 2023. This aligns Roth 401(k)s with Roth IRAs, whose owners have no lifetime RMD obligation.
What happens to my employer match in a Roth 401(k)?
Historically, employer matching contributions were generally allocated to a pretax account. Under SECURE 2.0, a plan may allow certain vested matching contributions to be designated as Roth if the plan offers this feature and the election is made by allocation and is irrevocable. A Roth-designated match is included in gross income for the year it is allocated.
Can I roll over a Roth 401(k) into a Roth IRA?
Yes. An eligible rollover distribution from a designated Roth 401(k) account may generally be rolled over into a Roth IRA. A direct rollover sends the funds straight to the new account with no taxes withheld from the transferred amount.
How does an IRA rollover bonus work?
Crypto.com pays a match on qualifying transfers or 401(k) rollovers with no dollar cap, though the rate depends on your tier: Basic earns 1%, Plus and Pro earn 2%, subject to program terms.
