On October 13, 2023, the Department of Treasury and the IRS
issued the last round of
final regulations implementing changes to the rules for
supporting organizations ("SOs") under section 509(a)(3)
of the Internal Revenue Code, as enacted by the Pension Protection
Act of 2006. These final regulations largely adopt proposed
regulations released in February 2016, and among other things
contain technical rules for supporting organizations of
governmental entities, clarify distribution requirements for
non-functionally integrated Type III SOs, and provide the
definition of "control" for purposes of the prohibition
on Type I and Type III SOs receiving contributions from persons who
control the governing body of a supported organization of that
SO.
