Social Security and Medicare: How They Work Together in 2026
Social Security and Medicare are closely linked but separate programs. Understand how they interact and what changes in 2026 mean for your benefits.
Social Security and Medicare are two pillars of retirement security for Americans, yet many people don't fully understand how these programs interact. Your Social Security benefits directly affect your Medicare premiums, enrollment timing, and even which savings programs you can access. Here's how these two essential programs work together in 2026.
How Social Security and Medicare Are Connected
2026 Social Security and Medicare Numbers
The COLA-Premium Squeeze
In 2026, the Social Security cost-of-living adjustment (COLA) is 2.5%, adding about $49 to the average monthly check. However, the Part B premium increased by $17.90/month. This means about 37% of the average COLA increase is consumed by the Part B premium hike.
IRMAA: When Higher Income Means Higher Medicare Costs
If your modified adjusted gross income (MAGI) exceeds certain thresholds, you'll pay higher premiums for both Part B and Part D through Income-Related Monthly Adjustment Amounts (IRMAA).
The Hold Harmless Provision
The "hold harmless" provision protects most Social Security recipients from Part B premium increases that would reduce their Social Security check. If the Part B premium increase is larger than your COLA increase, the provision limits your Part B premium increase to your COLA dollar amount. This protection applies to about 70% of beneficiaries.
Who Is NOT Protected by Hold Harmless?
The hold harmless provision does not apply to people who are new to Medicare, pay IRMAA, don't collect Social Security yet, or have their premiums paid by Medicaid or a state program. These individuals pay the full standard premium regardless of COLA amounts.
Timing Decisions: When to Claim Social Security
Your Social Security claiming age can affect your Medicare costs. If you delay Social Security past 65, you won't have premiums automatically deducted — you'll need to pay Part B premiums directly. If you claim Social Security early (before 65), you'll still need to enroll in Medicare separately when you turn 65.
