Retirement Account Tax Strategies: 401k, IRA, and Roth
Understanding the tax implications of different retirement accounts can help you build wealth more efficiently and reduce lifetime taxes.
Retirement Account Tax Strategies
Traditional 401(k) and IRA
- Contributions are pre-tax (reduce current taxable income)
- Growth is tax-deferred
- Withdrawals in retirement are taxed as ordinary income
- 2025 Contribution Limits: 401(k) $23,500; IRA $7,000 ($8,000 if 50+)
Roth 401(k) and Roth IRA
- Contributions are after-tax (no current deduction)
- Growth is tax-free
- Qualified withdrawals in retirement are tax-free
- Great if you expect to be in a higher tax bracket in retirement
Roth IRA Income Limits (2025)
- Single: Phase-out $150,000–$165,000
- Married Filing Jointly: Phase-out $236,000–$246,000
Backdoor Roth IRA
High earners who exceed Roth IRA income limits can contribute to a traditional IRA and then convert to a Roth (the "backdoor" strategy).
Required Minimum Distributions (RMDs)
- Begin at age 73 for traditional accounts
- Roth IRAs have no RMDs during the owner's lifetime
Roth Conversion Strategy
Convert traditional IRA funds to Roth during low-income years (e.g., early retirement) to reduce future RMDs and tax liability.
