Data for the Complete History of AMT Available February 22, 2007 Andrew Chamberlain Andrew Chamberlain We’ve posted a new data set this afternoon with the complete history of AMT tax returns and liabilities from 1969 to 2005. Although it’s not often reported in news stories on the AMT, the tax actually began as a 10 percent “minimum tax” in 1969, and wasn’t fully replaced by the current “alternative minimum tax” until 1982. For a full legislative history of the tax, see the appendix at the end of our 2005 AMT backgrounder. Click here to view the full data. Stay informed on the tax policies impacting you.
