Short answer: You can contribute to an HSA when you turn 65 only if you’re not enrolled in Medicare and you’re covered by an HDHP; if you enroll in Medicare, you must stop contributions six months before enrollment, though catch-up contributions are available at 65+.

How turning 65 affects HSA eligibility

As you approach 65 years old, it's essential to understand how to compute your HSA contribution for that year. When you turn 65, you become eligible for Medicare, which impacts your HSA contribution limit.

As you approach the milestone of turning 65, it’s crucial to grasp how your HSA contributions should be calculated for that particular year. Turning 65 makes you eligible for Medicare, which has implications for your HSA contribution limits that you need to be familiar with.

Rules for continuing or stopping contributions

Here's how you can calculate your HSA contribution in the year you turn 65:

  • Know that turning 65 does not affect your HSA eligibility; you can still contribute to your HSA if you're enrolled in a high-deductible health plan (HDHP).
  • If you're enrolled in Medicare, you can no longer contribute to your HSA. You must stop contributing to your HSA six months before you enroll in Medicare.
  • If you're still working and covered by an HDHP, you can delay enrolling in Medicare and continue contributing to your HSA. Once you retire or lose your HDHP coverage, you must stop contributing to your HSA.
  • If you're 65 or older, you can make catch-up contributions to your HSA. The catch-up contribution limit for individuals aged 55 or older is $1,000 per year.
  • Consult with a financial advisor or tax professional to ensure you're following the rules and maximizing your HSA benefits in the year you turn 65.

To calculate your HSA contribution during the year you turn 65, keep in mind the following steps:

Catch-up contributions and professional guidance

  • Remember that reaching the age of 65 does not eliminate your eligibility to contribute to an HSA. You may continue contributing as long as you're covered under a high-deductible health plan (HDHP).
  • If you enroll in Medicare, contributions to your HSA must cease. You are required to stop these contributions six months ahead of your Medicare enrollment.
  • If you’re still in the workforce and maintain an HDHP, you have the option to postpone your Medicare enrollment, allowing you to keep contributing to your HSA. However, it's necessary to stop contributions once you retire or lose the HDHP coverage.
  • Individuals aged 65 and older are eligible for catch-up contributions to their HSA, allowing for an additional $1,000 contribution each year for those over 55.
  • Consider consulting a financial advisor or tax expert to ensure you’re navigating these regulations effectively and making the most of your HSA benefits as you turn 65.
