Article 76 bis 4 aligns the tax treatment of 'profit' in Islamic finance with 'interest' in conventional finance. It mandates that any amounts received 'in lieu of interest' are treated as taxable income under Article 35. Conversely, any amounts spent 'in lieu of interest' are treated as deductible expenses, subject to the rules issued by the Chairman under Article 59. This ensures that the economic equivalent of interest in a Sharia-compliant transaction is recognized by the Tax Authority, providing level footing for both Islamic and conventional financial institutions and their clients.
