Accounting Errors That Do Not Affect The Trial Balance
There are certain accounting errors that do not affect an accounting trial balance, including:
Error of total omission
This occurs when an accounting entry is completely omitted from the book of accounts. In such a case, the trial balance totals will still balance as no entry was ever made.
Original entry error
This occurs when the original entry was either overstated or understated by a certain amount. For instance, original purchases might be $200, but the accountant mistakes it for $100. The accountant then debits the purchases ledger account with $100 and credits the cash account or the creditors account with $100. This error will not affect the trial balance.
