The U.S. Government Accountability Office (GAO) released its audit of federal lobbying compliance for 2013.

For the audit, the GAO reviewed a random sample of 104 quarterly disclosure reports filed for the third and fourth quarters of calendar year 2012 and the first and second quarters of calendar year 2013. Among its findings, the GAO concluded 96 percent of filers of lobbying disclosure reports were able to provide documentation to support reported income and expenses, 92 percent filed the required federal political campaign reports, and 67 percent of the reported income and expenses were properly rounded to the nearest $10,000. The audit also found at least 17 percent of all lobbying disclosure reports did not properly disclose formerly held covered positions.

The 56 page report, released on May 28, 2014, is titled “2013 Lobbying Disclosure Observations on Lobbyists’ Compliance with Disclosure Requirements.”
