Leading authorities on best judgment assessment
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.
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 unaccounted receipts or suppressed sales are detected and books of account are rejected under Section 145(3), additions to income must be restricted to the profit element embedded in such transactions, not the entire transaction value. This profit element is to be estimated by considering the assessee's regular profit ratio as per books of account.
When assessing income from undisclosed or unrecorded sales, the entire sale proceeds cannot be added to the assessee's income; instead, only the net profit embedded in such unaccounted sales, determined by applying the assessee's net profit rate, should be taxed.
The Supreme Court holds that an Assessing Officer, when making a best judgment assessment or estimating income, must act fairly, honestly, and rationally, basing the estimation on available material and avoiding arbitrary or capricious decisions. Adherence to natural justice principles is crucial during assessment proceedings.
An income tax officer making a best judgment assessment must act honestly, not dishonestly, vindictively, or capriciously. They must make a fair estimate of the assessment, considering local knowledge, repute, and previous assessments.
A best judgment assessment must be based on wisdom, truth, and legal principles, not arbitrary caprice. While it involves estimation and guesswork, this must have a reasonable nexus to available material and the case's circumstances.
Best judgment assessments under Section 144 must be a fair and rational estimation of income by the Assessing Officer, not capricious or arbitrary. Appellate authorities should accept clarificatory evidence to test the fairness of such assessments, even if produced for the first time.
