I'm filing a final Form 1041 for my deceased parents living trust. The last time I filed a 1041 for this trust was 2001 and the two years prior to that. It's been 19 years and the trustee and address have changed since then. Do I need to file form 8822B with the change of address? Does a Form 56 also need to be filed? Or should I just mark the "initial" return box?
