HSA and Medicare: Maximizing Your Healthcare Savings

What is an HSA (Health Savings Account)?

A Health Savings Account (HSA) is a tax-advantaged savings account designed to help individuals with high-deductible health plans (HDHPs) save money for future healthcare expenses. Contributions to an HSA are tax-deductible, and the funds can be used tax-free to pay for qualified medical expenses, including doctor visits, prescription medications, and even some over-the-counter items.

One of the key advantages of an HSA is that the funds roll over year after year if they are not used, unlike flexible spending accounts (FSAs), which have a use-it-or-lose-it policy. Additionally, HSAs can serve as a supplemental retirement account, allowing individuals to invest their funds and grow their savings tax-free.

However, things can get a bit more complicated when you reach age 65 and become eligible for Medicare. Let’s dive deeper into how HSA contributions and usage change once you enroll in Medicare and what strategies you can use to maximize your benefits.

Can You Contribute to an HSA After Enrolling in Medicare?

One of the most important things to know is that once you enroll in Medicare Part A or Part B, you are no longer eligible to contribute to an HSA. This is because the IRS requires that you have a high-deductible health plan (HDHP) to make contributions to an HSA, and enrolling in Medicare disqualifies you from having an HDHP.

When to Stop HSA Contributions

If you plan to enroll in Medicare, you need to stop contributing to your HSA at least six months before your Medicare enrollment date. Why? Because Medicare Part A coverage is often retroactive for six months from your enrollment date (but no earlier than your 65th birthday). Continuing to contribute to your HSA during this retroactive period could result in tax penalties.

For example:

• If you turn 65 in June and enroll in Medicare in December, your Medicare Part A coverage could be retroactive to June. Therefore, you would need to stop contributing to your HSA by June to avoid any penalties.

What Happens to Your HSA Funds After Enrolling in Medicare?

While you can no longer contribute to an HSA once you enroll in Medicare, you can still use the funds already in your account to pay for qualified medical expenses. In fact, HSAs can be a valuable tool for covering out-of-pocket healthcare costs during retirement.

Qualified Expenses for HSA Funds Post-Medicare Enrollment

After enrolling in Medicare, you can use your HSA funds to pay for:

• Medicare Part B premiums
• Medicare Part D premiums
• Medicare Advantage (Part C) premiums
• Copayments, coinsurance, and deductibles
• Dental, vision, and hearing care (which are not typically covered by Medicare)
• Long-term care insurance premiums (up to IRS limits)

However, you cannot use HSA funds to pay for Medigap (Medicare Supplement) premiums.

Tax Implications for Non-Qualified Expenses

If you use your HSA funds for non-qualified expenses, those withdrawals will be subject to income tax. However, once you reach age 65, you will no longer face the additional 20% penalty for non-qualified withdrawals that applies to younger individuals.

HSA Strategies for Individuals Approaching Medicare Eligibility

To make the most of your HSA before and after enrolling in Medicare, consider the following strategies:

1. Max Out Your HSA Contributions Before Enrolling in Medicare

If you are approaching age 65 and still working, maximize your HSA contributions before you enroll in Medicare. For 2024, the contribution limits are:

• $3,850 for individuals
• $7,750 for families
• An additional $1,000 catch-up contribution if you are age 55 or older

By maxing out your contributions, you can build a substantial balance that can be used to cover healthcare costs in retirement.

2. Delay Medicare Enrollment if You Are Still Working

If you are still employed and have health insurance through your job, you may be able to delay enrolling in Medicare without facing late enrollment penalties. This can allow you to continue contributing to your HSA. However, you must ensure that your employer coverage qualifies as creditable coverage under Medicare rules.

3. Use HSA Funds for Medicare Premiums

One of the most tax-efficient ways to use your HSA funds after enrolling in Medicare is to pay for your Medicare Part B, Part D, and Medicare Advantage premiums. This can help reduce your out-of-pocket costs in retirement.

4. Plan for the Six-Month Retroactive Medicare Coverage

As mentioned earlier, Medicare Part A coverage is often retroactive for six months. Make sure to stop HSA contributions in advance to avoid any penalties. Work with a financial advisor to determine the best timeline for stopping contributions based on your specific circumstances.

How HSA Rules Differ for Spouses

If you and your spouse both have HSAs, the rules for contributions and usage can vary depending on who is enrolled in Medicare.

• If one spouse enrolls in Medicare, they must stop contributing to their HSA. However, the other spouse can continue to contribute to their own HSA if they are still eligible.
• You can also use HSA funds from one spouse’s account to pay for the other spouse’s qualified medical expenses, even if that spouse is enrolled in Medicare.

Understanding HSA and Medicare Penalties

Failing to follow HSA rules after enrolling in Medicare can result in significant tax penalties. Here’s a quick breakdown of potential penalties:

• Excess Contributions: If you contribute to your HSA after enrolling in Medicare, you may be subject to a 6% excise tax on the excess contributions.
• Failure to Stop Contributions: As mentioned earlier, continuing to contribute to an HSA during the six-month retroactive Medicare coverage period can result in penalties. Ensure you stop contributions on time.
