The month Medicare coverage begins, change your HSA contribution to zero dollars to avoid a tax penalty. Keep in mind that after you enroll in Medicare, you may continue to withdraw money tax-free from your HSA to help pay for qualified medical expenses such as deductibles, premiums, copayments, and coinsurance.
Delay enrolling in Medicare if you want to continue contributing pre-tax to your HSA. You will also need to delay collecting Social Security retirement benefits to avoid automatic enrollment in Medicare Part A and B.
If you delayed enrolling in Medicare on your initial eligibility date, Medicare Part A may be backdated up to 6 months prior to your actual enrollment date. HSA contributions are not allowed during this backdated coverage period.*
If your covered spouse/domestic partner is ineligible for an HSA, but you are eligible, you must limit your election to the single HSA limit minus the employer contribution if you receive one. Keep in mind, you can still use your HSA to pay for your spouse/domestic partner’s eligible expenses.
*For questions about taxes, please consult a tax professional.
Age 65 Distributions
Once you reach age 65, you can take penalty-free distributions from your HSA for any reason. However, in order to be both tax-free and penalty-free the distribution must be for a qualified health care expense. Withdrawals made for other purposes will be subject to ordinary income taxes.
Using HSA Funds
If you have an existing balance in your HSA while you are covered by Medicare, you can continue to use your available funds to pay for your eligible medical, prescription, dental and vision expenses tax and penalty-free.
