Block assessment limits undisclosed income to evidence-backed receipts; estimated valuation alone cannot justify undisclosed investment additions.

Under Chapter XIV-B, income already reflected in earlier returns and supported by employer records, tax deduction evidence, advance tax, and self-assessment tax payments cannot be treated as undisclosed income merely because a return was filed belatedly; such receipts must be excluded from block assessment. An addition for alleged undisclosed investment based only on a DVO's estimate of house property alterations was unsustainable where no seized material or contemporaneous evidence linked the expenditure to the block period, and an earlier approved valuer's report showed the additions were completed before that period. The block assessment was therefore limited to income proved by material evidence.

Issues: (i) Whether the assessee's income under the heads salary, commission, house property, capital gains and income from other sources could be treated as undisclosed income in the block assessment. (ii) Whether the addition of Rs. 5,12,400, based on the DVO's estimate of cost of additions and alterations to the house property, was sustainable as undisclosed investment.

Issue (i): Whether the assessee's income under the heads salary, commission, house property, capital gains and income from other sources could be treated as undisclosed income in the block assessment.

Analysis: The income in question had been regularly reflected in earlier returns and was supported by employer records, audit particulars, tax deduction at source, advance tax and self-assessment tax payments. The material before the Tribunal showed no concealment or intention to suppress these receipts from the Department. The Tribunal applied the scheme of Chapter XIV-B and held that income not falling within the definition of undisclosed income under section 158B could not be brought to tax merely because the return for the year was filed belatedly.

Conclusion: The issue was decided in favour of the assessee. The income under those heads could not be treated as undisclosed income and had to be excluded from the block assessment.

Issue (ii): Whether the addition of Rs. 5,12,400, based on the DVO's estimate of cost of additions and alterations to the house property, was sustainable as undisclosed investment.

Analysis: The addition rested only on the valuation estimate. No seized material or other contemporaneous documentary evidence linked the alleged construction expenditure to the block period. The approved valuer's report showed earlier additions and alterations completed up to 1982-83, and that report was not properly displaced by any reliable contrary material. In the absence of evidence connecting the alleged expenditure with the block period, the estimate could not support an addition as undisclosed investment under section 158BB.

Conclusion: The issue was decided in favour of the assessee. The addition of Rs. 5,12,400 was directed to be deleted.

Final Conclusion: The block assessment was confined to undisclosed income established by material evidence, and the impugned additions were not sustainable on the facts proved before the Tribunal.

Ratio Decidendi: Income regularly recorded, disclosed through tax compliance and unsupported by seized material cannot be treated as undisclosed income in block assessment, and an estimated valuation without corroborative evidence cannot sustain an addition for undisclosed investment.
