31. MAT & AMT — Minimum Tax Rules
MAT (Minimum Alternate Tax) and AMT (Alternate Minimum Tax) are special tax provisions introduced to ensure that taxpayers claiming substantial deductions and exemptions still pay a minimum level of tax to the government.
These provisions become extremely important where normal taxable income is reduced significantly because of deductions, incentives, depreciation, or special tax benefits.
Under the Income-tax Act, 1961 and the Income-tax Act, 2025 (effective from 01/04/2026), MAT and AMT continue to remain major anti-tax-avoidance mechanisms in Indian taxation.

To address this situation, the government introduced:
- MAT → Mainly for companies
