A trial balance is not an account but  a list of balances extracted form the
ledger   to test the   arithmetical accuracy of the ledger  entries. It 
is a statement containing the 
various ledger balances on a particular 
date.
The statement is prepared in the form of schedule containing two columns (One for debit balances, the other for credit balances ). If the books of accounts are arithmetically accurate, then the two sides of the trial balance must tally.
The statement is prepared in the form of schedule containing two columns (One for debit balances, the other for credit balances ). If the books of accounts are arithmetically accurate, then the two sides of the trial balance must tally.
The  trial  balance however, proves only one aspect of
the ledger accounts ie . the 
equality  of debit and credit  entries. It does not prove that transactions
have been correctly  analyzed and
recorded in the proper accounts.  Despite
this limitation however,  the  trial balance serves the following purposes:
a.      It 
provides  proof for the
arithmetical accuracy of   the  accounting  
entries 
b.      It forms the basis for preparing
the financial  statement such as the
profit and loss account and the balance 
sheet, and 
c.      It summarizes the entire ledger
accounts  thereby making it possible for
the position of a particular account to be judged simply by looking at the
trial balance 
A profoma of a trial balance is as follows:
