Roth vs. Traditional IRA: The Golden Tax Decision

Choosing between a Roth IRA and a Traditional IRA comes down to one simple question: Will your tax rate be higher today, or higher when you retire?

1. How a Roth IRA Works (Pay Taxes Today)

  • You contribute post-tax dollars (no upfront tax deduction).
  • Your investments grow 100% tax-free.
  • All qualified withdrawals in retirement are 100% tax-free!
  • No Required Minimum Distributions (RMDs) during the owner's lifetime.

2. How a Traditional IRA Works (Pay Taxes Tomorrow)

  • You contribute pre-tax dollars, lowering your taxable income this year.
  • Your investments grow tax-deferred.
  • Withdrawals in retirement are taxed as ordinary income.
  • Mandatory RMDs begin at age 73 (or 75 under SECURE 2.0).

3. The Deciding Rule of Thumb

If you are early in your career in a low tax bracket (10% or 12%), the Roth IRA is almost always superior. If you are in peak earning years (24% to 37%), the upfront deduction of a Traditional IRA is often more beneficial, provided you invest the annual tax savings.
