and even that gets difficult Self employment tax follows one spouse estimated taxes go one way investment income what if you lived in a nonCP state? does that stat have a reciprocal agreement? software only goes so far. they would need a good support system

and like Louisiana's CP law differs from California's, differs from Washington's. we pay 20k for our software and we still have to do these calcs mostly on our own before telling software how to do it. your individual taxpayer is gonna be lost. i think DF is great and i think it works for a lot

Still don't really understand what the system wouldn't be able to do. The state/states would feed it with information it should already have that the system would then just use to calculate and give output.
