The Compliance Center computers are programmed to select those returns with high DIF scores which reflect issues that could be easily resolved by mail. The computers select those returns which are appropriate for correspondence audits and each respective return is reviewed by either a Tax examiner or clerk. The returns are DIF screened and quality reviewed using technically proficient examination personnel who are experienced in DIF screening operations. Returns which have apparent examination issues other than those appropriate for correspondence audit are referred to the local Area Office. Some examples of the kinds of items which can be verified by correspondence are itemized deductions, such as interest, taxes, contributions, medical expenses, and simple miscellaneous deductions such as union dues and small tools. Issues other than itemized deductions may be examined if they are single matters which would not be appropriate for office audit or field examination.
About 7 million U. S. Taxpayers fail to file required income tax returns each year, while 146 million Americans dutifully file their returns each year. That means that about 5% of the populace fail to meet their obligations to Uncle Sam. As part of its National Research Program the IRS released a study in 2011 of 2006 returns which found that as result of non-filing, the government loses $28 billion per year. Although the IRS makes efforts to force non-filers into compliance, the continuing improvident cutting of the IRS budget allows more taxpayers to duck their filing obligations because the IRS has fewer resources to pursue non-compliant taxpayers.
