Q&A: Medicare and HSA Contributions

What do you do when an employee is Medicare-eligible but they’re also contributing to the company-sponsored health savings account (HSA)?  Check out the Q&A below for more information.


If an employee turns age 65 this month and enrolls in Medicare Part A, can he still receive/contribute funds into an HSA until the end of the year?


The employee may contribute to his HSA only while he meets all four eligibility criteria – is enrolled in a qualifying High Deductible Health Plan (HDHP), does not have any disqualifying non-HDHP coverage, is not enrolled in Medicare, and cannot be claimed as another taxpayer’s tax dependent. Eligibility is determined on a monthly basis, so contributions cannot be made for a particular month unless he meets all the eligibility criteria that month.

The tax law governing HSAs sets an annual limit on maximum contributions. For 2018, the annual limit is $3,450 (if enrolled for single HDHP coverage) or $6,900 (if enrolled for family HDHP coverage). For persons age 55 and older, an additional catch-up contribution of $1,000 is allowed. If not eligible for all 12 months of the calendar year, the annual limit is pro-rated. For instance, if the employee was eligible each month from January through May, then became covered for Medicare on June 1, his maximum allowable HSA contribution for 2018 would be 5/12ths of the usual annual limit.

Employees participating in HSAs are encouraged to review their own situation with their personal tax advisor.
