Tax Savings Opportunities
Maximize 401(k) Contributions
Contributing the full $23,500 to your 401(k) reduces your taxable income dollar-for-dollar. If your employer offers a match, contribute at least enough to capture the full match — that's an immediate 50–100% return.
401(k) Age 50+ Catch-Up Contribution
Workers 50 and older can contribute an additional $7,500 per year, for a total of $31,000. This accelerated savings window significantly reduces taxable income near retirement.
Open a Roth IRA for Tax-Free Growth
Roth IRA contributions are after-tax but all qualified withdrawals in retirement are tax-free. Eligible for single filers with MAGI below $150,000 (full contribution) to $165,000 (phase-out). Best for those expecting a higher tax bracket in retirement.
Solo 401(k) or SEP-IRA for Self-Employed
Self-employed individuals can shelter up to 25% of net self-employment income in a SEP-IRA (max $70,000 in 2025), or combine employee + employer contributions in a Solo 401(k) for even higher limits.
