  • Tax Return
    A unique lifetime planning tool,
    DecoupleCruncher helps prepare
    federal and state returns.


Starting in 2002, many states decoupled their estate taxes from the federal system by choosing to apply their own estate tax regardless of the availability of a federal estate tax credit.  DecoupleCruncher is the solution to crunching the numbers in cases where client property is located in one or more decoupled or quasi-decoupled states.  The program allows for the completion of hundreds of computations, many with interrelated variables, in a matter of seconds.
