The 2013 column (and beyond) in the 2012 ATX software seems to be kicking out an incorrect number for personal exemptions. It calculates the 2013 personal exemption limitation correctly up through the phase out range (AGI of $300,000 to $453,900 for MFJ). However, when I reach $453,901 of AGI the allowable deductions go from $0 to the full amount ($15,600 for 4 exemptions). This amount is $1 over the phase out threshold of $153,900, ignoring the last $2,500 bucket. ($453,000 - $300,000 = $153,901). Has anyone else experienced this?
