There are a range of things that could lead the Internal Revenue Service to decide to audit a given tax return. Among these are concerns related to credits claimed in the return. One type of tax credit that is involved in quite a few audits here in the U.S. is the earned income tax credit.
This can be seen in statistics from the IRS’ most recent annual data book. Reportedly, over a third (36.7 percent) of the just over 1 million IRS audits of individual tax returns that occurred in the 2016 fiscal year were initiated over concerns related to the earned income credit.
