It has been mentioned a number of times the last couple of weeks. I am not sure there is an easy answer, but based on comments it appears that the health insurance marketplace, has linked information on persons with policies to the IRS in time for this filing season.

Several preparers have reported that they had clients who "were just looking around and didn't intentionally sign up" that actually did have insurance, even when they paid no premiums. If this is the case you cannot get the return accepted without getting the 1095-A and reconciling it.

One mentioned answer is for the clients to call the marketplace (that is not the correct name, but it is in some other posts) and ask if they have a 1095-A and get a copy of it.
