You Can't Contribute to a Health Savings Account Once You're on Medicare. A Bipartisan Bill in Congress Would Change That

  • Once you're on Medicare, even if only Part A, you are no longer permitted to put money in an HSA.
  • A growing number of people are likely to reach age 65 — the point at which you become eligible for Medicare — with an HSA.
  • The bill in the House to change contribution rules would also eliminate two other benefits that Medicare beneficiaries with HSA money currently can take advantage of.

There's a renewed push in Congress to let Medicare beneficiaries set aside pretax money for medical expenses.

Called the Health Savings for Seniors Act and introduced this month in the House, the bipartisan bill revives past legislative efforts to let individuals on Medicare contribute to health savings accounts, or HSAs, which they currently cannot do. Yet with a growing number of workers using these accounts, more people are likely to reach age 65 — the point at which you become eligible for Medicare with an HSA in tow.

"Many clients who have established HSA accounts think that they can continue funding the HSA past enrollment in Medicare," said Elizabeth Gavino, founder of Lewin & Gavino and an independent broker and general agent for Medicare plans. "They're usually surprised to find out they can't."

The bill does come with a tradeoff: It would remove the ability to use HSA withdrawals to pay for Medicare premiums — something that's currently allowed. It also would eliminate penalty-free withdrawals for nonmedical expenses in the 65-and-older crowd as now permitted.

At the end of 2021, there were 32 million of these accounts — up 8% from 2020 — holding an aggregate $98 billion, according to a recent report from investment consultant Devenir.  Annual contributions to HSAs for 2022 are limited to $3,650 for someone with individual coverage and $7,300 for family coverage. People age 55 or older can put an extra $1,000 in per year.

HSAs come with a triple tax benefit: Contributions are tax-deductible, earnings are tax-free, and withdrawals also are untaxed as long as they are used to cover qualified medical expenses. Roughly 28% of workers are enrolled in such a plan, up from 17% in 2011, according to 2021 research from the Kaiser Family Foundation. 

However, you can only contribute to an HSA if you have a so-called high-deductible health care plan — and Medicare coverage does not fall in that category. Beneficiaries are permitted to use their HSA funds to pay for medical expenses, yet cannot set up a new HSA or contribute to one.

While people who are still working can sign up for Medicare at age 65, many choose to continue using their employer's health plan alongside Medicare Part A (hospital coverage) and, perhaps, Part B (outpatient care). If it's a high-deductible plan paired with an HSA, they can continue making those pretax contributions to the account only if they delay signing up for Medicare altogether.

"A lot more companies are going to high-deductible plans, and a lot more people are working longer," said Kathleen Holt, associate director for the Center for Medicare Advocacy. "And they're stumbling into these rules around HSAs."

For 2022, a high-deductible health plan is one with a deductible of at least $1,400 for an individual or $2,800 for family coverage, with maximum annual out-of-pocket costs (not counting premiums) of no more than $7,050 (for an individual) and $14,100 (family plan). That excludes out-of-network costs.

The Medicare program does have something similar to HSAs called medical savings accounts, although they are not broadly used — roughly 5,600 beneficiaries were in health plans that used them in 2019, according to the Kaiser Family Foundation.

These so-called MSAs are paired with a high-deductible Medicare Advantage Plan (which some beneficiaries choose), but individuals cannot contribute to the account. The insurer that offers the plan makes the contributions — an amount that could vary from year to year — and you can make tax-free withdrawals to cover medical expenses.

Also, MSA plans do not include Part D prescription drug coverage, according to the Centers for Medicare and Medicaid Services.

It's uncertain whether the House bill will gain any momentum. While the 2019 version of the measure accumulated co-sponsors, it never made it out of committee.
