401(k) vs IRA: How to Maximize Your Retirement Tax Savings

Traditional vs. Roth Tax Treatment
Both 401(k)s and IRAs come in two tax flavors:
- Traditional (Tax-Deferred): You contribute pre-tax dollars today, reducing your current income tax bill. Your investments grow tax-free, but withdrawals in retirement are taxed as ordinary income.
- Roth (Tax-Free Growth): You contribute after-tax dollars today. Your money grows tax-free, and all qualified withdrawals in retirement are 100% tax-free.
The Optimal Retirement Contribution Waterfall
Financial planners recommend following this exact priority order to maximize your tax savings and returns:
- Step 1: Get the Full Employer 401(k) Match. If your employer matches 50% up to 6% of salary, that is an immediate 50% return on your money. Never leave free money on the table!
- Step 2: Max out a Roth IRA. Enjoy lower fees, better investment selection, and tax-free withdrawals.
- Step 3: Return to Max out your 401(k). Up to the annual limit ($23,500).
