Maybe for the company - BUT NOT for you ...
That extra money is TAXABLE income to you ...
For example, lets say you are single and a policy will cost you $4K ...
About 30% of that "income" will be taxable to you [$1.2K] in the form of Federal, State, FICA, etc.
So, now you have $2.8K for your healthcare that costs $4K ...
HELLO - YOU now need to pony up the $1.2K difference in order to get your healthcare ...
I think it should be taxable.
It is compensation (income).
No matter what you have left after taxes, you shop for the best deals on everything ... so why not insurance and medical care too?
