| Employer match | No | Yes — effectively free money |
| Income limits for contribution | Yes — phases out $150K-$165K (single) | No income limits |

(1) 401(k) up to the employer match — this is a 50-100% instant return on investment that cannot be beat. (2) Max Roth IRA — $7,000/$8,000 in tax-free savings. (3) Return to 401(k) for additional contributions up to $23,500 total. This order maximizes free money and tax diversification.
When Roth IRA Beats 401(k) as the Priority
- Your 401(k) plan has poor investment options with high fees — a bad plan may not be worth contributing beyond the match
- You are in the 12% or 22% bracket — locking in tax now at low rates is especially valuable
- You value the flexibility of Roth IRA contributions being withdrawable (the 401k is less accessible)
- Your employer does not offer a match — without the match, 401k loses its most compelling advantage over Roth IRA
- You have a long time horizon and want to maximize tax-free compounding over decades
- Your estate planning goals include leaving tax-free assets to heirs
The Roth 401(k): Best of Both Worlds
Many employers now offer a Roth 401(k) option — combining the higher $23,500 contribution limit of the 401(k) with the after-tax, tax-free growth treatment of a Roth IRA. If your employer offers it, the Roth 401(k) is often the ideal primary vehicle for retirement savings, particularly for workers in the 12%-24% bracket who believe taxes will be higher in retirement.
