A. No. If your employer offers you affordable insurance (i.e. your share of the premium does not exceed 9.5 percent of your income), you are not eligible for a subsidy. He is already subsidizing your insurance by paying part of the premium.
But, beginning in 2014, small employers will be able to shop for insurance in their own exchanges, where they can purchase coverage for their employees. There, they will become part of a large group, and eligible for the substantially lower premiums that large companies pay. If your employer decides to share the savings, your share of the premium could fall.
