While automatically enrolled on a pre-tax basis, you are able to choose post-tax premium payments if you wish.
In order to do this, you must obtain, complete and submit a Medical Spending Conversion (MSC) Premium Conversion Enrollment/Change Form available at your Agency's Human Resources Department, or by contacting the MSC Administrative Office directly at (212) 306-7760.

After You Have Completed the Form
The completed form should be returned to your Agency's Human Resources Depatment for completion of the benefit section and to sign the MSC Enrollment/Change Form and send it to the MSC Administrative Office for processing.
Changing from pre-tax to post-tax or vice-versa can be done during the annual Health Benefits Fall Transfer Period. However, employees must choose to pay on a pre-tax or post-tax basis for an entire Plan Year.
