Who gets the tax credit me or my boss?

my employer issues me a monthly check (made payable to me) to cover the cost of insurance premiums. I pay taxes on this money at the end of the year as none are taken out each month when the check is issued. This year they want receipts from the insurance company and want to claim the premium on the business taxes. Is this right? I feel the money, because it is credited as wage, is ours to claim on our taxes and quite frankly to do whith as we choose.
