HSA and Medicare: What You Need to Know

Writer: Premier One Financial CompanyPremier One Financial Company

Health Savings Accounts (HSAs) are a popular way to save for medical expenses tax-free, but when it comes to Medicare, there are important rules and considerations to keep in mind. Understanding how HSAs interact with Medicare can help you make informed financial and healthcare decisions as you approach retirement.


What Is an HSA?

An HSA is a tax-advantaged savings account designed for individuals with a high-deductible health plan (HDHP). Contributions to an HSA are tax-deductible, the money grows tax-free, and withdrawals for qualified medical expenses are also tax-free. This makes HSAs a powerful tool for managing healthcare costs before and during retirement.


How Does Medicare Affect Your HSA?

Once you enroll in Medicare, you can no longer contribute to an HSA. However, you can still use the funds already accumulated in your account to pay for qualified medical expenses, including Medicare premiums, deductibles, copayments, and other healthcare-related costs.


Key Considerations When Transitioning to Medicare

  1. Stopping HSA Contributions: If you enroll in Medicare at age 65, you must stop contributing to your HSA. Contributions made after Medicare enrollment may result in tax penalties.

  2. Delaying Medicare Enrollment: If you continue working past age 65 and have an employer-sponsored HDHP, you may choose to delay Medicare enrollment and continue making HSA contributions. However, once you enroll in Medicare, contributions must cease.

  3. Medicare Premium Payments: You can use HSA funds to pay for Medicare Part B, Part D, and Medicare Advantage plan premiums, but not Medigap (Medicare Supplement) premiums.

  4. Six-Month Lookback Rule: If you enroll in Medicare after age 65, your Medicare coverage may be retroactive for up to six months. To avoid excess HSA contributions, stop contributing to your HSA at least six months before enrolling in Medicare.


Using HSA Funds in Retirement

Even though you can’t contribute to an HSA after enrolling in Medicare, you can continue to use your funds tax-free for qualified medical expenses. Some eligible expenses include:

  • Medicare Part B and Part D premiums

  • Long-term care expenses and insurance (subject to limits)

  • Dental, vision, and hearing expenses not covered by Medicare

  • Out-of-pocket medical costs such as copayments and deductibles
