IRMAA thresholds differ by how you filed in the lookback year.
Who is on Medicare?
IRMAA applies per person. If both spouses are enrolled, the surcharge applies to each one separately.

MAGI = AGI + tax-exempt interest. From your lookback year tax return.
Any big income moves planned?
These will be added to your base MAGI to show the impact. Leave at $0 to skip.
