National Tax Association
This organization, founded in 1907, "is the leading association of
tax professionals dedicated to advancing understanding of the
theory and practice of public finance." The association focuses on
the debate of public finance issues, theory testing and research.
The site provides information on membership to the NTA, the index
to the National Tax Journal from 1948-98, plus a host of links to
other tax-related websites.
