Practical Strategies to Save Money
Enroll During the 7-Month Initial Enrollment Window
Enrolling during your IEP prevents the permanent 10% per year Part B late enrollment penalty and ensures uninterrupted medical coverage.
Manage MAGI 2 Years in Advance to Avoid IRMAA Cliffs
Because IRMAA uses a 2-year lookback, high-income retirees should plan Roth conversions and capital asset sales before ages 63 and beyond.
Take Advantage of the Medigap Guaranteed Issue Window
During your 6-month Medigap Open Enrollment Period starting at age 65, private insurers cannot deny coverage or charge higher premiums for pre-existing conditions.
Factor in the 2025/2026 $2,000 Part D Prescription Cap
Under the Inflation Reduction Act, out-of-pocket prescription drug costs are capped at $2,000/year, providing catastrophic protection for expensive specialty drugs.
