Use Schedule J (Form 1041) to report an accumulation distribution for a domestic complex trust that was:
Previously treated at any time as a foreign trust (unless an exception is provided in future regulations), or
Created before March 1, 1984, unless that trust would not be aggregated with other trusts under the rules of section 643(f) if that section applied to the trust.
An accumulation distribution is the excess of amounts properly paid, credited, or required to be distributed (other than income required to be distributed currently) over the DNI of the trust reduced by income required to be distributed currently. To have an accumulation distribution, the distribution must exceed the accounting income of the trust.
