Social Security & Medicare
Social Security and Medicare are connected, but they are not the same thing. Understanding how they work together can help you avoid missed deadlines, penalties, and confusion as you plan for retirement.
The Big Thing To Know
You do not have to start Social Security in order to get Medicare. Many people enroll in Medicare at 65 while waiting until later to claim Social Security.
The mistake is assuming one automatically takes care of the other. Sometimes it does. Sometimes it does not.
Common Questions
Start with the question that matches what you are trying to figure out.
Do I have to take Social Security to get Medicare?
No. Medicare and Social Security are separate decisions. You can delay Social Security and still enroll in Medicare.
Does Medicare start automatically?
Sometimes. If you are already receiving Social Security before 65, Medicare may start automatically. If not, you may need to sign up.
Can I work while receiving Social Security?
Yes. But if you are under Full Retirement Age, earnings limits may affect your benefit temporarily.
What is Full Retirement Age?
Full Retirement Age is when you become eligible for your full Social Security retirement benefit.
When should I claim Social Security?
That depends on your income needs, health, work plans, spouse, and retirement goals.
What happens at age 70?
Delayed retirement credits stop at age 70. There is generally no benefit increase for waiting longer.
Social Security & Medicare Timeline
These are the ages most people should understand when planning Medicare and Social Security.
Earliest Social Security Retirement Benefits
Most people can begin Social Security retirement benefits as early as age 62, but starting early usually means a permanently reduced monthly benefit.
Medicare Eligibility Begins
Medicare eligibility generally begins at 65. This is true even if you decide to wait until later to claim Social Security.
Full Retirement Age
Full Retirement Age is usually between 66 and 67, depending on your birth year. Once you reach Full Retirement Age, Social Security earnings limits no longer reduce your benefit.
Maximum Delayed Retirement Credits
Social Security delayed retirement credits stop at age 70. Waiting beyond 70 generally does not increase your benefit.
Add These Milestones To Your Roadmap

Social Security is about retirement income. Medicare is about health coverage. They often show up at the same stage of life, which is why people confuse them.
If you are already receiving Social Security before age 65, Medicare may begin automatically. If you are delaying Social Security, you may need to actively enroll in Medicare yourself.
This is especially important if you are still working, covered by an employer plan, contributing to an HSA, or planning to retire after 65.
