Number: RS22083 Title: Alternative Minimum Taxpayers by State: 2005, 2006, and Projections for 2008 Authors: Steven Maguire, Government and Finance Division Abstract: In 2006, 4.1 million taxpayers were subject to the AMT. New Jersey, Connecticut, New York, the District of Columbia, and Maryland had the highest percentage of taxpayers subject to the AMT. South Dakota, Tennessee, Alaska, Mississippi, and North Dakota had the lowest percentage of taxpayers subject to the AMT. In 2008, absent legislative change, according to the Joint Committee on Taxation, some 25.7 million taxpayers will be affected by the AMT. At that time, whether a married taxpayer has itemized deductions for state/local taxes or miscellaneous deductions will become a much less important factor than it is at present in determining AMT coverage. This occurs because, whether they itemize their deductions or not, married taxpayers across a wide range of the income spectrum will be subject to the AMT because personal exemptions are not allowed against the AMT.
