## Actionable Steps to Maximize the Benefit
- **Review your age class:** If you're aged 60-63 and working in a plan that allows the higher catch-ups per SECURE 2.0, adjust contributions accordingly.
- **Check employer plan rules:** There may be deadlines to change your elective deferral percentage or contribution elections—don’t miss them.
- **Traditional vs Roth IRAs:** Know your eligibility for deduction or contribution phase-outs. The income ranges for deductible traditional IRA contributions, Roth IRA eligibility, and the Saver’s Credit have all shifted upward.

- **Budget for cash flow:** Higher contributions reduce take-home pay in the short term—plan your budget, especially during the holidays or big-expense months.
## Compliance Tips for Employers and Plan Administrators
- Update payroll systems to recognize the new contribution limits before 2026.
- Communicate changes to employees: send notices, hold education sessions.
- For SIMPLE IRA plans, note that catch-ups also adjust; ensure administrators know which plans allow which limits.
## Example Scenario
Imagine **Lisa**, aged 62, contributing to a 401(k) plan in 2026. She could contribute the base $24,500 plus the higher catch-up amount ($11,250 under SECURE 2.0) for a total possible deferral of **$35,750**. If Lisa’s employer also offers matching, her total retirement savings surge compared to 2025.
## Final Thoughts
Raising retirement contributions offers a big opportunity for your long-term tax and savings strategy—especially if you're in your fifties or early sixties. Confirm your eligibility, update your settings early, and consider consulting with a financial professional to ensure every dollar works for your retirement—and your tax benefit.
