What is the Roth 401(k) contribution limit for 2026?

The Roth 401(k) and Traditional 401(k) share the same limit: $24,500 in 2026 ($32,500 with the standard catch-up for ages 50-59 / 64+, or $35,750 with the SECURE 2.0 super catch-up for ages 60-63). The limit is combined across both account types — you cannot contribute $24,500 to each.

Does a Roth 401(k) have required minimum distributions?

No. Starting in 2024, Roth 401(k) accounts are no longer subject to required minimum distributions during the owner's lifetime. This aligns the Roth 401(k) with the Roth IRA and is one of the most significant changes from SECURE 2.0.

Can I contribute to both a Traditional 401(k) and a Roth 401(k)?

Yes, if your employer plan allows it. The combined total across both types cannot exceed the annual limit ($24,500 in 2026). For example, $12,000 Traditional + $12,500 Roth = $24,500 total.

Does a Roth 401(k) have income limits?

No. Unlike the Roth IRA, there are no income limits for contributing to a Roth 401(k). High earners who are phased out of Roth IRA contributions can still use a Roth 401(k) without restriction.

What happens to my Roth 401(k) when I change jobs?

You can roll your Roth 401(k) to a Roth IRA or a new employer's Roth 401(k) tax-free. Rolling to a Roth IRA is often preferred as it eliminates any future RMD requirements and provides more investment flexibility.

Which Keeps More Money — Assuming Same Tax Rate?

If your tax rate is the same in retirement as it is today, the math is exactly equal. The winner depends entirely on whether your rate goes up or down.

📊 Traditional 401(k) — 22% bracket

Gross contribution$10,000

Tax saved now (22%)+$2,200

Net cost to you now$7,800

Grows to (30 yrs @ 7%)$76,100

Tax owed in retirement (22%)-$16,740

Net after-tax$59,360

✅ Roth 401(k) — 22% bracket

Gross contribution$10,000

Tax owed now (22%)-$2,200 (paid separately)

Net contribution to account$10,000

Grows to (30 yrs @ 7%)$76,100

Tax owed in retirement$0

Net after-tax$76,100

Note: The Roth shows higher after-tax because $10k was contributed (vs. effectively $7,800 from the Traditional after accounting for the tax savings invested elsewhere). On an equal-net-dollar basis (investing the Traditional tax savings in a taxable account), the outcome is nearly identical when tax rates are the same. The Roth wins when rates rise; Traditional wins when rates fall.

Decision Guide

Which Should You Choose?

Choose Traditional 401(k) if…

You're in the 32%+ bracket now and expect 22% or lower in retirement
You need to maximize take-home pay and the tax deduction matters
You're very close to retirement and won't have decades of tax-free compounding
You plan to use Roth conversions strategically during low-income retirement years
State taxes are very high now (moving to no-income-tax state in retirement)

Choose Roth 401(k) if…

You're in the 12% or 22% bracket and expect similar or higher rates later
You're early-career with decades of tax-free compounding ahead
Your income is too high for a Roth IRA but you want Roth exposure
You want to avoid RMDs and maintain flexibility in retirement
You're concerned about rising tax rates (e.g., expiring TCJA provisions after 2025)
You want to leave a tax-free inheritance to your heirs

💡 Split the difference: Many financial planners recommend splitting contributions between Traditional and Roth 401(k) — for example, $12,000 Traditional + $12,500 Roth. This gives you tax diversification and the flexibility to draw from either bucket depending on which is most tax-efficient in a given retirement year.

FAQ

Common Questions

Can my employer match go into a Roth 401(k)?

Starting in 2023, SECURE 2.0 allows employer match contributions to go into a Roth 401(k) if your plan allows it. Historically, employer match always went into the Traditional (pre-tax) side. Check your plan documents to see if this option is available.

Does the Roth 401(k) have an income limit?

No. This is a major advantage over the Roth IRA, which phases out at $153,000–$168,000 (single) in 2026. Anyone with access to a Roth 401(k) can contribute, regardless of income. This makes it the preferred Roth vehicle for high earners.

What happened to Roth 401(k) RMDs under SECURE 2.0?

Prior to 2024, Roth 401(k)s were subject to RMDs, which was a significant drawback compared to Roth IRAs. SECURE 2.0 eliminated this requirement starting in 2024 — Roth 401(k) account owners no longer need to take RMDs during their lifetime. This makes the Roth 401(k) much more attractive for estate planning.

Should I roll my Roth 401(k) to a Roth IRA when I leave my job?

Often yes. Rolling a Roth 401(k) to a Roth IRA is a tax-free event, and Roth IRAs offer more investment flexibility, no plan restrictions, and no RMDs. However, note that the Roth IRA has a 5-year clock that starts from your first Roth IRA contribution — a new rollover doesn't restart this if you already have an existing Roth IRA. Check the 5-year rules carefully before doing the rollover.
