How Much Can I Contribute to an HSA in the Year I Start Medicare?

When it comes to contributing to a Health Savings Account (HSA) in the year you start Medicare, there are certain rules and limitations to be aware of. First off, if you are enrolled in Medicare, you are no longer eligible to contribute to an HSA. However, there are some exceptions to this rule:

If you are still eligible for an HSA even after enrolling in Medicare, you can continue to contribute to it. Here are some scenarios where this might apply:

  • If you are enrolled in Medicare but have not yet started receiving Social Security benefits
  • If you are enrolled in Medicare but your spouse is still covered by an employer-sponsored health plan

It's important to note that the maximum contribution limits for HSAs are different for individuals and those with family coverage. For the year 2021, the contribution limits are:

  • Individual Coverage: $3,600
  • Family Coverage: $7,200

Individuals aged 55 and older can make an additional catch-up contribution of $1,000 per year. However, if you enroll in Medicare mid-year, your contribution limit will be prorated. This means that you can only contribute a portion of the annual limit based on the number of months you were eligible to contribute.


When considering contributions to your Health Savings Account (HSA) in the year you start Medicare, it’s vital to know that once you are officially enrolled in Medicare, you become ineligible to make further contributions to your HSA.
