Common confusion points
Do I need to file a separate Form 56 for each taxpayer?
Form 56 allows multiple taxpayers on one form (Part II), but many filers submit a separate form for each decedent or trust
→ List all taxpayers on Part II of one Form 56 if they share the same fiduciary
What if my fiduciary relationship is not recognized by a court?
Part III asks for a court date, but some relationships (e.g., by trust agreement) lack a court order
→ If not court-appointed, leave line 8a blank and attach a copy of the trust or other authority
Can I file Form 56 electronically?
The IRS accepts e-filing of Form 56 through approved software, but many filers still mail paper forms
→ Check IRS e-file partner list for software that supports Form 56
Do I need to file Form 56 for every year I act as fiduciary?
Form 56 is filed only when the relationship begins, ends, or changes — not annually
→ File Form 56 once at the start; file a new one only if the fiduciary or address changes
What is the difference between Form 56 and Form 8822-B?
Form 56 notifies of fiduciary authority; Form 8822-B changes address for the taxpayer
→ Use Form 56 for fiduciary status changes; use Form 8822-B only for an address change when no fiduciary relationship exists
Can an executor use Form 56 to request a tax clearance certificate?
Form 56 establishes authority; a separate closing letter for the estate (Form 4810 or 5486) is needed
→ File Form 56 early; then file for a closing letter after all taxes are paid
