Roth or Traditional? Answer this one question

Do you expect a higher tax rate in retirement than today? If yes → Roth. If no → Traditional. Same math for everyone.

Roth wins for young high earners now in a low bracket, anyone expecting higher future taxes, and heirs (no RMDs).

Traditional wins if you're in a peak-earning year now and expect to retire in a lower state or bracket. Convert Traditional to Roth in low-income years.
