I am not sure I believe this one. IA makes pension income non-taxable if the taxpayer is 55 or older. Out taxpayer is 57 and the spouse is 54. Taxsim assigns pension income to the older spouse if there is a mixed age couple, so I did that in TA also, and got the very low taxable income. It looks like PE splits the pension, but does make it non-taxable for the older taxpayer. I prefer the Taxsim way, and I believe PE does that in some other states, but I can't name them now. I could test if you like.
