I'm willing to bet something like this will be done but I don't know if it's the explanation of the "audit activities" phrase. Since you can apply for subsidies that take income into account, it stands to reason they would need to do the occasional audit to determine if your current income matches what you claim on the exchange. How to do that? Well, the IRS is heavily involved in the enforcement of these laws so it stands to reason that every once in a while the exchange will compare notes with the IRS to make sure your stated income on both forms match. I expect this to happen sometime after April every year. I'd be curious if there are penalties outlined in the law about getting extra subsidies based on lying on the exchange about your income levels. If you decide to read the law and get to that part of the monstrosity, then let us know what it says.
