The Taxation Laws (Amendment) Act, 1975 - Explanatory notes on the provisions coming into force with effect from October 1, 1975.

Enlarged enforcement powers against tax evasion: increased search, seizure, provisional attachment and criminalisation strengthen revenue protection.

The Act expands powers to detect and recover undisclosed income by enlarging search, seizure and survey authorities, authorising requisition of documents from other agencies, and introducing a rebuttable presumption as to ownership and contents of books and assets seized. It restructures jurisdictional and delegation rules among tax officers, tightens recovery by imposing director and partner liability and enabling provisional attachment, adjusts appeal admission to require payment in specified cases, and strengthens penal provisions by creating new offences, enhancing imprisonment terms, and assigning corporate and family criminal liability.
