Pros & Cons
10 pros·4 cons across both
Roth IRA
Pros
- Tax-free withdrawals in retirement on gains and contributions
- No required minimum distributions (RMDs) during your lifetime — funds grow indefinitely
- Can withdraw contributions (not earnings) anytime penalty-free
- No income limits for converting existing 401(k) funds via backdoor Roth strategy
- Tax-free growth for 30+ years maximizes compound interest benefit
Cons
- Income phase-out begins at $146,000 single/$230,000 married in 2026, eliminating eligibility for higher earners
- Maximum $7,000 annual contribution is significantly lower than 401(k), limiting wealth-building capacity
401(k)
Pros
- Employer match provides up to 6% average free money (immediate 100% return on investment)
- Much higher contribution limit of $23,500/year allows faster wealth accumulation
- Pre-tax contributions reduce current taxable income dollar-for-dollar
- No income limits — available to all workers regardless of earnings
- Borrowing provision allows loans against balance (up to $50,000 or 50% of vested balance)
Cons
- Withdrawals in retirement are taxed as ordinary income, potentially at higher rates than current tax bracket
- Required minimum distributions begin at age 73, forcing taxable withdrawals regardless of need
Frequently Asked Questions
5 questions
Roth IRA: You can withdraw contributions anytime penalty-free, but earnings before age 59½ face 10% penalty + income tax (exceptions exist). 401(k): Withdrawals before 59½ trigger 10% penalty + income tax, but some plans allow loans (up to $50,000) or hardship withdrawals with documentation. The Roth offers more flexibility for accessing contributions without penalty.
