communication from Jerry Tempalski; and IRS.
(1) Calendar years. The data for the years 1970 to 1998 has been obtained from Harvey and Tempalski (1997) table 2 and private
communications. For the years 1999 to 2003, the number of AMT taxpayers and the AMT revenue under current and extended law have
been calculated by adding TPC microsimulation model estimates of the number of taxpayers with lost credits and the revenue due to
these lost credits to the IRS published actual figures for those with direct AMT liability. For 2004-15 under all three scenarios, and for
pre-EGTRRA law from 2001-3, estimates are from the TPC microsimulation model.
(2) Includes those with direct AMT liability on Form 6251 and those with lost credits. Tax units that are dependents of other taxpayers
are excluded from the analysis.
(3) Includes direct AMT liability on Form 6251 and lost credits.
(4) Includes extension of all provisions in EGTRRA that sunset 12/31/10 and all non-AMT provisions in JGTRRA and WFTRA.
(5) Includes repeal of all provisions in EGTRRA, JGTRRA, and WFTRA and is thus equivalent to pre-EGTRRA law.
