I read the article. It's extremely unclear to me whether you have ACA-compliant health insurance or not. I've been a startup principal since 2005 and have had PEO coverage at various points since the ACA passed, and it was always ACA-compliant. Could you just answer the question? It shouldn't be a riddle!
(Note that "non-ACA insurance" doesn't mean "insurance you didn't buy on the ACA public marketplace". I've got Anthem Blue Cross through our benefits provider. It is very definitely ACA-compliant.)
