Difference between certified balance sheet

When tax audit required u/s. 44AB of IT act, or by any equivalent act/authority, the balance sheet or financial statements are certified by the auditor to be compliant to the respective act or rules, is called audited balance sheet.

But when the statements are not required to be audited, but are required by some agencies like bank for loan purpose etc, in that case CA certifies the statements as to be true to his knowledge, or as per books of accounts maintained, in that case it is said to be certified BS.
