You still own your HSA and you can continue to use it to pay for qualified medical expenses. But you will not be able to make new contributions to your HSA. Please note if there is no activity on the account, funds could be turned over to the state after a number of years of inactivity (this varies by state). If there are no funds in the account, the account could be closed after a certain amount of time of inactivity. Contact the Hess Benefits Center at Fidelity to see what could happen under any of these scenarios.
