Answer:
The post closing trial balance contains all accounts that are in the General Ledger, with the exception of any "closed accounts" such as revenue, expenses, etc.
A post closing trial balance is created after all adjusting entries and closing has been done to the ledger.
My first answer I answered with Trial Balance or Adjusted Trial Balance in mind, as stated above, Post Closing Trial Balance is filled out AFTER all expense, revenue, and other related accounts have been closed.
