1.ERRORS WHICH DO NOT AFFECT THE AGREEMENT OF A TRIAL BALANCE RESULT DUE TO:-
1. Omission of figure(s); It is among the errors in which it occurs when a transaction is completely omitted from the books.
Example: If we sold Tshs. 10,000/= goods to Usama but did not enter it in either sales or Usama’s personal account, the trial balance will still balance.
2. Commission; This is where the correct amount is entered but in the wrong personal account.
Example: where a sale of 100/= to K. Asaad is entered in the account of B. Asaad . It will be noted that the correct class of account was used; both the account concerned being personal accounts.
3. Original entry:
This error occurs when the original figure is incorrect, yet double entry is still observed using this incorrect figure. An instance of this could be where there were sales of 4500/= goods but an error is made in calculating the sales Invoice. If sales was calculated as 4300/= and credited as Sales and debited to the personal account of the customer, the customer, the trial balance will still balance.
4. Reversal of entries;
Where the correct accounts are used but each item is shown on the wrong side of account.
Example: Supposed we had purchased goods at 1200/= the double entry of which is Cr. Cash 1200/= and Dr. purchases 1200/=. In error it is entered as Cr. Purchase1200/= and Dr. Cash 1200. The Trial balance will still agree.
5. Application of principle;
Where an item is entered in which wrong class of account.
6.
Compensating of figures;
Where errors cancel out each other. If the Sales account was added up to be 600/= too high and the purchases a/c also added up to be 600/= too high, then these two errors would cancels out in the trial balance.
2.ERRORS WHICH AFFECT THE AGREEMENT OF A TRIAL BALANCE RESULT:
(i) Incorrect additions either total too great or too small in any account.
(ii) Entering an item on only one side of the book.
For instance, if the debit entry is made but not the credit entry (once recording only).
(iii) Posting an entry twice in the books of accounts on the same side.
E.g. Dr. Sales 500 and Dr. Cash A/C 500 or vice – versa.
(iv) Failing to post an entry to the trial balance.
E.g. Balance of 100/= From Discount a/c is totally forgotten, not posted to trial balance through an account has been prepared.
(v) Entering one figure on the debit side of the books but another figure on the credit side.
E.g. If 800/= for cash received from K. Usama is entered in the cash book but 8,000/= is entered in respect of it in Usama’s A/c
SUSPENSE ACCOUNT
Is an A/C opened and used in corrections errors which can cause disagreement of the trial balance.
Since errors are discovered in trial balance, so as to prepare final accounts at the end of accounting period to enable work on the trial balance is often transferred to a temporary ledger account called suspense account. Either by debiting or crediting.
