As far as ACA is concerned, it is important to know that ACA requires health insurance and will soften the blow with subsidized insurances (when purchased via a health insurance exchange). The government subsidies are not based on your assets, but only on your income.
As a result, anything you earn from the stocks you own, for example, is still income. However, assets in IRAs or plain old bank accounts will not count against you in terms of insurance. In other words, the nest egg is not meant to be threatened by the health insurance requirement.
