Best judgment turnover estimates need a rational nexus to seized material; penalty for an incorrect return stands where suppression is proved.

Enhancement of gross turnover in a best judgment assessment must rest on a rational estimate with a reasonable nexus to the material found during inspection; where loose papers and irregular accounts show suppression but do not establish the extent of concealment, a guess-based enhancement and reduction of deduction for tax-paid goods will not stand. The matter was therefore remanded for fresh determination of concealment. Penalty for furnishing an incorrect return was sustained because the suppression and undisclosed transactions made the return incorrect, so the statutory basis for penalty was attracted.

Issues: (i) whether the enhancement of gross turnover and reduction of deduction for tax-paid goods were sustainable on the material found during inspection; (ii) whether penalty for furnishing an incorrect return was justified.

Issue (i): whether the enhancement of gross turnover and reduction of deduction for tax-paid goods were sustainable on the material found during inspection.

Analysis: The assessment could rest on best judgment only if the estimate of escaped turnover had a rational basis and a reasonable nexus with the material discovered. The seized loose papers and irregular accounts indicated suppression, but the authorities did not determine the extent of concealment or connect the material with a defensible estimate of sales and purchases. The enhancement, particularly for the relevant assessment year, was therefore found to be excessive and based on guesswork rather than a bona fide estimate.

Conclusion: The enhancement of turnover and the reduction in deduction were not sustained and the matter was required to be reconsidered for fresh determination of concealment.

Issue (ii): whether penalty for furnishing an incorrect return was justified.

Analysis: The return was found to be incorrect in view of the suppression and the undisclosed transactions revealed in the investigation. On those facts, the statutory basis for penalty was attracted, and the levy could not be treated as arbitrary.

Conclusion: The penalty was upheld as justified.

Final Conclusion: The assessment was set aside in part and the matter was remanded for fresh assessment on the question of concealment, while the penalty was sustained.

Ratio Decidendi: An estimate of escaped turnover in best judgment assessment must have a rational basis and a reasonable nexus with the material found, and penalty for an incorrect return is sustainable where suppression is established.
