Regarding the efforts you're talking about, we have two programs within the agency. One is what we call “filing and remittance compliance”, which refers to collecting accounts receivable, but it also refers to getting people to file returns that have not filed returns. That activity altogether represents about 19% of our program activity, or about $615 million in total.
We also have a program that we refer to as “reporting compliance”. That's where people have filed returns but we're auditing the returns to ensure that the returns are correct and that all income is reported. As I say, we call that program “reporting compliance”, which represents about 34% of our total or approximately $1.1 billion.
