The document provides a comprehensive overview of Minimum Alternate Tax (MAT) and Alternate Minimum Tax (AMT) as regulated by the Income Tax Act of 1961, detailing their objectives, applicability, and computation methods. MAT ensures that corporate taxpayers minimally contribute to tax even after deductions and exemptions, while AMT applies to non-corporate taxpayers with specific income levels and deductions.
