Can You Contribute After-Tax Dollars to a HSA Account After Medicare Coverage Starts?

One question many individuals have about their Health Savings Account (HSA) is whether they can continue contributing after-tax dollars to their HSA account after they enroll in Medicare coverage. The answer is yes, but there are some important details to consider.

When you enroll in Medicare, you are no longer eligible to contribute to an HSA if you have enrolled in any part of Medicare, including Part A for hospital insurance, Part B for medical insurance, or Part D for prescription drug coverage. However, you can still contribute after-tax dollars to your HSA if you delay enrolling in Medicare.

If you delay enrolling in Medicare and continue contributing after-tax dollars to your HSA, you should be aware of the following:

  • You cannot contribute to your HSA for any month in which you are enrolled in Medicare.
  • If you delay enrolling in Medicare and continue contributing to your HSA, you should notify your HSA administrator and stop contributions once you enroll in Medicare to avoid any tax penalties.
  • After enrolling in Medicare, you can use the funds in your HSA tax-free for qualified medical expenses, including Medicare premiums, copays, and deductibles.
  • It's important to understand the rules and regulations regarding HSAs and Medicare to avoid any penalties or tax liabilities.

While it is possible to contribute after-tax dollars to your HSA after Medicare coverage starts, it's essential to stay informed about the eligibility criteria and rules to ensure you maximize the benefits of your HSA.


Many people are curious about whether they can continue adding after-tax contributions to their Health Savings Account (HSA) once they begin receiving Medicare benefits. The answer is slightly nuanced, but generally, if you have enrolled in any part of Medicare, contributions to your HSA are no longer allowed. However, if you choose to postpone your Medicare enrollment, you can continue to make after-tax contributions to your HSA.
