Estimated income addition cannot support section 270A penalty where books are rejected and income is assessed on estimation.

Penalty under section 270A was stated to be unsustainable where the assessment addition arose from rejection of books under section 145(3) and estimation of income. The Tribunal's reasoning was that an estimated addition does not provide a stable basis for levying penalty for under-reporting, so the assessee's challenge on this ground succeeded. The alternative plea on immunity became academic once the primary ground was accepted. The document therefore states the principle that penalty under section 270A should not be sustained on an income addition founded purely on estimation.

Issues: Whether penalty under section 270A of the Income-tax Act, 1961 was leviable where the addition in assessment was made by rejecting the books of account under section 145(3) and estimating income.

Analysis: The assessing officer had rejected the books of account, estimated the assessee's income at 15% of gross receipts, and made an addition on that basis, before levying penalty for under-reporting of income under section 270A. The Tribunal held that where the addition is founded on estimation of income, there is no sustainable basis to levy penalty for under-reporting, and the assessee's primary challenge succeeds. As the appeal was accepted on this primary ground, the alternative plea relating to immunity became academic.

Conclusion: Penalty under section 270A was not sustainable on the estimated addition, and the assessee succeeded.
