Outside of the subsidized Exchanges, many employees will pay substantially more for individual plans than for employer sponsored group coverage. Otherwise, group plans would cease to exist.
It is fundamentally unfair to advocate that some Exchange members pay with pre-tax money when the rest must pay with after tax money, given that subsidies are based on taxable income.
"Fully sponsored" plans, where the employer pays the whole thing, are extremely rare & have no relevance to the discussion.
That's not what I asked. I asked if there was a practicable difference between sponsoring a fully-insured plan or paying your employees to buy individual insurance. There is not.
First, you must understand that I said "fully-insured" and not "fully sponsored". A fully insured plan is not one in which the employer pays the whole premium, it is one in which all of the morbidity risk is borne by a commercial insurer. In other words, there is no self-insured retention by the employer. This means that the entire plan is subject to commercial market regulation, just like an individual plan.
Second, you must understand that the discussion at hand is not whether employer-sponsored plans are inherently better or worse, either from a benefits standpoint or tax standpoint, than individual plans. The discussion is whether an employer sponsoring a group plan and paying the insurer a portion of the premium (using pre-tax money) is any different than the employer giving the employee pre-tax money to buy an individual plan. In my opinion it is not. In fact, it can be worse.
We know that one of the goals of the ACA was to increase the level of coverage in individual market plans. It did that through the EHB mechanism, which actually set benefits to identical (or near identical) levels as group plans. The result was an overall increase in individual market premiums. But those individual market premiums may just be lower than similar group premiums.
My state is kind enough to provide a rate lookup tool. I've used it to determine that an individual market silver premium (2nd lowest) in Las Vegas is ~$20 per month cheaper than a comparable small group plan. In Esmeralda county it's ~$40 per month cheaper.
Admittedly large group is not small group and there may be some variation, but it at least lets us know that individual and large group are in the ballpark.
So, to the employee, there's likely no discernible cost difference between the two options.
As far as benefits go, employees may be better off in the individual market. Why? Some of the ACA reforms don't apply to the large group market, or are applied differently.
Additionally, one of the reasons that large groups are historically cheaper than individuals is due to overall morbidity being better. If the premiums are now similar between the individual and large group markets but the large group morbidity is still better then large employers "dumping" people into the individual exchanges will make premiums even better as the overall risk pool (and resultant index rate) improve.
