Surplus stock classification: accounting linkage to business determines treatment as business income over unexplained investment.
Classification of surplus stock found during a section 133A survey depends on its nexus with ordinary trading and documentary accounting. Where excess inventory is recorded in the stock register and credited to partners' capital account, these accounting entries indicate it forms part of regular business stock and support treatment as business income rather than unexplained investment under section 69B, affecting applicability of special tax treatment under section 115BBE.
