How to Choose Between a Roth IRA and a 401(k)

• Your age: If you’re younger, you may benefit more from a Roth IRA due to its tax-free growth potential. If you’re closer to retirement, a 401(k) with employer-matching contributions may be more attractive due to the immediate tax advantages compared to a Roth account.
• Your income: If you earn above a certain income threshold, you may not be eligible to contribute to a Roth IRA.
• Your employer’s benefits: If your employer offers a Roth 401(k) with matching contributions, this can be a significant advantage for your retirement savings.
• Your retirement goals: Consider your long-term retirement goals and how much you need to save.
• Tax Situation: Consider whether you’d benefit more from tax breaks now (401(k)) or in retirement (Roth IRA).

Can You Have Both?

• Contribute enough to your 401(k) to get the full employer match
• Max out your Roth IRA if you’re eligible
• Return to your 401(k) if you can save more

This approach combines the best of both worlds: employer matching and tax diversification.

Special Considerations

• Spousal IRA contributions: Even if only one spouse works, you can contribute to a Roth IRA for a non-working spouse, as long as you file taxes jointly and have enough earned income to cover both contributions.

  • Inherited Roth IRAs maintain their tax-free status
  • Inherited 401(k)s require beneficiaries to pay taxes on withdrawals
