Most premiums are paid with pre-tax dollars, which means they are deducted from your wages before taxes are applied. Deducting them again as a self-employment expense would be "double-dipping."

You can only deduct the premiums if your employer included them in Box 1 (Gross Wages) of your W-2. However, this is highly unusual and contrary to the standard practice.

For accuracy sake, it would be best to check with your employer.
