Key Tax Official Plans to Step Down

Roger Colinvaux, legislation counsel to the Congressional Joint Committee on Taxation, has announced he is leaving his post at the end of April. He accepted a teaching job at Catholic University of America’s law school, in Washington.

Mr. Colinvaux helped shepherd key legislation for nonprofit groups, including a provision in the Pension Protection Act of 2006 that allows older donors to donate up to $100,000 tax-free from their individual retirement accounts to charities.
