DE income tax difference with TAXSIM35

[martinholmer]

The following integration test fails. It is not yet known whether the
tax logic problem is in TAXSIM35 or in the current PEUS code, or
whether there are problems in both models. This topic is meant to
facilitate discussion of why this test fails, primarily by reporting
the results of hand calculations required to fill out the relevant tax
form.

[PavelMakarchuk]

This was caused by the use of taxable income instead of income tax in the determining step of whether the tax unit files separately or jointly and will be fixed by #3935
