Schedule PC lets the estate’s fiduciary ask the IRS to hold the right to a refund while a claim or expense is still unresolved. The fiduciary provides the decedent’s details, describes the pending claim, and files the schedule together with Form 706.
The fiduciary of the estate of a decedent who died after December 31 2011 must file Schedule PC (Form 706).
Part I gathers the decedent’s name, Social Security number, fiduciary name, death date, address, and the number of claims (line 7). Part II details each claim or expense, and Part III lists any previously filed Schedule PC or Form 843.
First, complete Part I with the decedent’s identifying information and the number of claims on line 7. Next, fill Part II, checking the box that matches the claim type and entering the required dates and amounts. If the estate has filed another Schedule PC or Form 843, add the prior claim details in Part III. Finally, attach the completed Schedule PC to Form 706 and submit them together.
