The Congressional consensus for tax reform in 1986 grew around two maj
or principles: substantial rate reduction and improvement in horizonta
l equity. Tax legislation in the early 1980s foreshadowed these princi
ples, since it involved either rate reduction or base broadening (alth
ough not in the same package). This article describes tax legislation
that followed the Tax Reform Act of 1986 in order to see what new prin
ciples, if any, emerged as important forces. The objectives of several
of the current reform proposals appear to be inconsistent with those
driving recent legislation and with the consensus likely to be necessa
ry for fundamental tax reform. Thus, it may be a number of years befor
e such a consensus develops.
