Debatable tax adjustment under section 143(1) cannot deny section 115BAA benefit or invoke section 115JB without notice.

Processing under section 143(1) cannot be used to deny the benefit of the concessional tax regime under section 115BAA or invoke section 115JB where the issue is disputed and debatable. An adverse adjustment of this kind, made without issuing a show cause notice, exceeds the limited scope of prima facie processing. The intimation under section 143(1) was therefore held invalid and the adjustment was quashed.

Issues: Whether the adjustment made while processing the return under section 143(1) of the Income-tax Act, 1961, by denying the benefit of section 115BAA and invoking section 115JB, without issuing a show cause notice, was valid.

Analysis: The adjustment was made on a disputed and debatable issue relating to the assessee's entitlement to the concessional tax regime under section 115BAA. No show cause notice was issued before making the adverse adjustment. Such a controversy could not be treated as a permissible prima facie adjustment within the limited scope of processing under section 143(1).

Conclusion: The intimation under section 143(1) was invalid and could not be sustained; the adjustment denying the benefit of section 115BAA and invoking section 115JB was quashed.
