Roth IRA vs 401k: Which Retirement Account

The Roth IRA and 401k are two pillars of American retirement planning, but they have fundamentally different tax structures. A Roth IRA offers tax-free withdrawals in retirement, while a traditional 401k offers tax-deferred growth with an upfront deduction. Here is how to choose between them.

Our Verdict

Do not choose one over the other — use both. Step 1: Contribute to your 401k up to the employer match (free money). Step 2: Max out your Roth IRA ($7,000). Step 3: Return to 401k and contribute up to the $23,500 limit. This strategy captures the employer match, builds a tax-free Roth nest egg, and maximises total tax-advantaged savings.
