Every year, Social Security announces a cost-of-living adjustment: the COLA. For most retirees, it feels like a raise. But there is a catch that surprises a lot of people, and it is worth understanding before it catches you off guard.
For most seniors, Medicare premiums are not billed separately. They come straight out of your Social Security check. So when Medicare costs go up, which they do in most years, that increase quietly eats into the extra money you were expecting from your COLA.
Take 2017 as an example. That year’s COLA was just 0.3 percent. Medicare Part B premiums rose by more than that. For many retirees, the raise they expected simply disappeared into the higher premium.
There Is a Protection Built In
Here is the good news. A rule called the hold-harmless provision protects you from seeing your actual Social Security payment go down because of a Medicare premium increase.
In plain terms: if Medicare premiums rise more than your COLA, you will not pay the full new premium. You will only pay up to the amount of your raise. Your check stays the same, it just does not grow the way you hoped.
Back in 2017, the standard Medicare Part B premium was $134. But most retirees protected by the hold-harmless provision paid only around $109, not the full standard rate, because their small COLA could not cover the gap.
That protection had already been quietly working for them in earlier years when COLAs were low or nonexistent. The provision kept their premiums from jumping to the full standard amount each time.
The Catch You Need to Know About
There is a flip side. Once a larger COLA arrives, premiums for those protected retirees can jump back up to the full standard amount all at once. That can feel like a big hit in a single year.
The bottom line is simple. Social Security and Medicare are closely connected, and the size of your monthly check depends on both. Knowing how these two programs interact helps you plan ahead and keeps the surprises to a minimum.
