The key question: Will your tax rate be higher or lower in retirement than it is today?

The Income Factor

High earners: If you're in the 32% or higher tax bracket, Traditional 401(k) contributions provide significant current tax savings.

The Age-Based Strategy

Younger workers (20s-30s): Focus on Roth 401(k) contributions to lock in today's low tax rates and benefit from decades of tax-free growth.

Mid-career workers (40s-50s): Balance between Traditional and Roth contributions based on current tax bracket and retirement expectations.
