Can I Use My HSA to Pay for Medicare Advantage Premiums?

Health Savings Accounts (HSAs) offer a tax-advantaged way to save and pay for healthcare expenses. HSAs are available to individuals covered by high-deductible health plans (HDHPs). Medicare Advantage plans (Medicare Part C) are private alternatives to Original Medicare, often combining hospital, outpatient, and prescription drug coverage. Understanding how HSAs interact with Medicare, especially regarding Medicare Advantage premiums, is a common concern for those planning healthcare in retirement.

Understanding HSA and Medicare Enrollment

An HSA is a savings account for healthcare costs, available to individuals enrolled in a high-deductible health plan (HDHP). To qualify, an individual must be covered by an HDHP and have no other health coverage. HDHPs typically feature lower premiums but higher deductibles, meaning members pay more out-of-pocket before their insurance coverage begins. For 2025, an HDHP must have a minimum deductible of $1,650 for self-only coverage or $3,300 for family coverage.

Medicare, the federal health insurance program, generally covers individuals aged 65 or older, some younger people with disabilities, and those with End-Stage Renal Disease or ALS. Medicare Advantage plans are private health insurance options that provide Medicare Part A (hospital insurance) and Part B (medical insurance) benefits, often including Part D (prescription drug coverage). These plans operate within a network of providers and may offer additional benefits not covered by Original Medicare.

A significant rule governs the interaction between HSAs and Medicare enrollment: once an individual enrolls in any part of Medicare, they are no longer eligible to make new contributions to an HSA. This includes enrollment in Medicare Part A or Part B. The ineligibility begins in the month Medicare coverage becomes effective. This rule exists because to contribute to an HSA, you cannot have any health insurance other than an HDHP, and Medicare is considered other health coverage.

Individuals who are automatically enrolled in Medicare Part A due to receiving Social Security benefits must be particularly aware of this rule. If someone delays Medicare enrollment because they are still working and want to continue HSA contributions, they must also typically delay collecting Social Security retirement benefits, as receiving these benefits often triggers automatic Part A enrollment. It is also important to stop HSA contributions at least six months before enrolling in Medicare Part A because coverage can be retroactive for up to six months. Continuing contributions during this retroactive period can lead to tax penalties.

Even though new contributions are prohibited, individuals can still use existing funds in their HSA after enrolling in Medicare. This allows account holders to continue benefiting from the tax-free withdrawals for qualified medical expenses. The funds accumulated in an HSA prior to Medicare enrollment remain available for use throughout retirement.

Using HSA Funds for Medicare Advantage Premiums

HSA funds can be used for qualified medical expenses, including certain Medicare premiums. Specifically, HSA funds can pay for Medicare Part A premiums, Part B premiums, Part D (prescription drug coverage) premiums, and Medicare Advantage (Part C) plan premiums.

While HSA funds can cover these Medicare premiums, they cannot be used for premiums for Medicare Supplement (Medigap) policies. This distinction is important for beneficiaries planning their healthcare expenses. Using HSA funds for Medicare Advantage premiums allows individuals to leverage accumulated savings to offset ongoing healthcare costs in retirement.

The practical mechanism for using HSA funds often involves direct payment from the HSA administrator or the account holder paying out-of-pocket and then reimbursing themselves. Many HSA providers facilitate direct payments. Maintain accurate records of all qualified medical expenses and HSA distributions for tax purposes.

This flexibility in using existing HSA funds for Medicare premiums offers a valuable financial planning tool. Even though new contributions cease upon Medicare enrollment, the funds already saved can significantly reduce out-of-pocket costs associated with Medicare Advantage plans. This helps maximize the tax benefits of the HSA well into retirement.

Tax Treatment of HSA Withdrawals

Withdrawals from an HSA for qualified medical expenses are tax-free, including funds used for eligible Medicare Advantage premiums. The triple tax advantage of HSAs—tax-deductible contributions, tax-free growth, and tax-free withdrawals for qualified medical expenses—makes them a powerful savings vehicle.

If HSA funds are used for non-qualified expenses before age 65, these withdrawals are subject to income tax and an additional 20% penalty tax. For instance, a $1,000 non-qualified withdrawal would incur regular income tax plus a $200 penalty. This penalty discourages using HSA funds for non-medical purposes prior to retirement age.

Once an HSA account holder reaches age 65, the 20% penalty for non-qualified withdrawals is waived. However, if funds are withdrawn for non-qualified expenses at or after age 65, they are still subject to ordinary income tax. Withdrawals for qualified medical expenses, including Medicare premiums, remain tax-free regardless of age.

Maintaining detailed records of all medical expenses and HSA distributions is important. These records support the tax-free nature of qualified withdrawals and are necessary in case of an IRS audit. Proper record-keeping helps ensure compliance and allows account holders to fully benefit from their HSA’s tax advantages.
