A spokesman at the IRS announced yesterday that Deputy Commissioner Kevin Brown will become acting IRS commissioner May 4. Current Commissioner Mark Everson has accepted a position heading up the American Red Cross (see here and here for more on Everson's departure). In much the way a senior in college decided to go to graduate school to put off a decision about what to do with their life, the IRS said Brown would only be the acting commissioner for 25 days. For him to continue beyond that time would require White House approval. I don't know much about Kevin Brown (other than that I believe he pitched for a time for the Rangers and Dodgers and had a wicked sinker), but he has previously served as both counsel and then commissioner of the Small Business/Self-Employed Division at the IRS, which employs almost 44,000 workers and oversees the compliance programs for all individuals and small businesses. It serves 45 million taxpayers. Brown has also served as chief of staff to Everson, and joined the IRS in 1998 as Assistant to the Commissioner. He also participated in advising the agency during the Restructuring and Reform Act of 1998. At this point, there is no reason to believe that the White House will not approve of Brown's permanent appointment to be the IRS commissioner.
