“rejection of books of account”
The decision most relied on for rejection of books of account is Lalchand Bhagat Ambica Ram v. CIT (37 ITR 288), cited in 570 judgments on BharatTax.
Leading authorities on rejection of books of account
Where an assessee maintains regular books of account, and these books are not rejected or found defective by the Assessing Officer, any cash deposits or available cash shown in the cash book, if sufficient to cover the transaction, cannot be treated as unexplained income or an addition under sections 68 or 69A.
When books of account are rejected and unaccounted sales or receipts are discovered, the income addition is restricted to the net profit element embedded in these undisclosed transactions, not the entire sale proceeds or receipts, especially if corresponding purchases are not proven to be outside the books.
In a best judgment assessment, some guesswork is inherent, but the estimate must be fair and not arbitrary. Books of account can be rejected under Section 145(3) if the assessee fails to substantiate entries or prove the genuineness of transactions, leading to estimation of income.
An assessee must explain the source of entries in their account books and prove that the sums are not income; the department is not initially required to prove anything. However, the department cannot unreasonably reject a good explanation, thereby converting valid proof into no proof.
The Supreme Court established principles for best judgment assessments, stating that some guesswork is inevitable but the assessment must be bona fide, rational, and free from bias or capriciousness. An appellate authority cannot substitute its judgment for that of the Assessing Officer unless the AO's assessment is shown to be biased, irrational, vindictive, or capricious, especially when the assessee fails to provide proper accounts or counter-evidence.
When purchases are found to be entirely bogus and based on fictitious invoices from non-existent or unconfirmed suppliers, the entire amount of such purchases is liable to be added back as unexplained expenditure, not merely a percentage thereof.
When an assessee's income is estimated after rejecting their books of account, further additions or disallowances for specific expenses are generally not permissible, as the estimation already accounts for these.
For an Assessing Officer to make a valid reference to the Departmental Valuation Officer for the estimation of the cost of construction, the books of accounts must first be rejected under Section 145(3) of the Income-tax Act.
