21st Century Taxation

This blog by a tax professor is about tax policy and reform and moving tax systems into the 21st century. It focuses on tax system weaknesses, critiques reform proposals (pointing out where they do and do not follow principles of good tax policy and do and do not reflect how we live and do business today), and offers new ideas. Additional information - articles, reports and links, can be found at the 21st Century Taxation website (see link below right). I welcome your comments.
