How could the inclusion of Social Security income affect Robert's Medicare costs?
Social Security income may raise Medicare premiums for beneficiaries The inclusion of Social Security income in the Modified Adjusted Gross Income (MAGI) calculation means that beneficiaries who receive SS income may find their MAGI increases. Medicare uses MAGI to determine the Medicare Income-Related Monthly Adjustment Amount (IRMAA) surcharges. If an individual's MAGI crosses specific thresholds, they are subject to these surcharges, which result in higher annual Medicare premiums. For example, a couple with joint MAGI reaching $235,283 in 2026 could face a household surcharge of $2,296.80.

How it reaches Robert

Social Security income is now included in the Modified Adjusted Gross Income (MAGI) calculation. MAGI is used by Medicare to set Income-Related Monthly Adjustment Amount (IRMAA) surcharges. Medicare generally uses the tax return from two years prior to calculate these surcharges.

Social Security income is now factored into the Modified Adjusted Gross Income (MAGI) calculation, which is used by Medicare to determine IRMAA surcharges. SSA generally uses the tax return from two years earlier to set these premiums.

Everything about Social Security Administration -
Medicare sets IRMAA surcharges based on MAGI. Going even one dollar over a bracket triggers that tier's full surcharge, meaning that increased SS income can push a beneficiary into a higher premium tier.

Why it matters
For retirees like Robert, the IRMAA system acts as a financial cliff. Because the surcharge is triggered by crossing a threshold, even a small increase in MAGI due to Social Security income can result in a full tier's surcharge being applied to Medicare premiums.
This system is part of a larger financial risk for seniors, as the thresholds for IRMAA brackets rise with inflation, while the required minimum distributions (RMDs) from retirement accounts also rise yearly, potentially pushing beneficiaries into higher premium tiers.
