Roth IRA: Complete Guide to Tax-Free Retirement

How Roth IRAs work, contribution limits, income limits, and strategies to maximize tax-free growth.

What Is a Roth IRA?

A Roth IRA is an individual retirement account where you contribute after-tax money. Growth and qualified withdrawals in retirement are tax-free. You never pay taxes on the gains.

Key Benefits

  • Tax-free withdrawals in retirement.
  • No RMDs (required minimum distributions) during your lifetime—you can leave it to grow.
  • Flexibility: Withdraw contributions (not gains) anytime, penalty-free.
  • Tax diversification: Having both pre-tax (401k) and Roth gives you options in retirement.

Contribution Limits (2024)

  • $7,000 per year ($8,000 if 50+)
  • Income limits: Phase-out starts around $146k (single) and $230k (married filing jointly)
  • Backdoor Roth: If over the limit, contribute to Traditional IRA (non-deductible) and convert to Roth

Roth vs. Traditional IRA

  • Roth: Pay tax now, never again. Best when you expect higher taxes in retirement.
  • Traditional: Deduct now, pay tax on withdrawal. Best when you're in a high bracket now.

Young investors often prefer Roth—they're in lower brackets now and have decades of tax-free growth ahead.
