Practical Examples of MAT Calculation
Example 1: Domestic Company with High Book Profit
Scenario: ABC Ltd. has a book profit of ₹50,00,000 and taxable income of ₹10,00,000 for AY 2023-24.
Normal Tax Calculation: ₹10,00,000 × 25.17% (including surcharge and cess) = ₹2,51,700
MAT Calculation: ₹50,00,000 × 17.16% = ₹8,58,000
Tax Payable: Higher of the two = ₹8,58,000 (MAT applies)
MAT Credit: ₹8,58,000 – ₹2,51,700 = ₹6,06,300 (can be carried forward)
Example 2: Foreign Company with Low Taxable Income
Scenario: XYZ Inc. (foreign company) has book profit of ₹30,00,000 and taxable income of ₹5,00,000 for AY 2023-24.
Normal Tax Calculation: ₹5,00,000 × 43.68% (including surcharge and cess) = ₹2,18,400
MAT Calculation: ₹30,00,000 × 17.16% = ₹5,14,800
Tax Payable: Higher of the two = ₹5,14,800 (MAT applies)
MAT Credit: ₹5,14,800 – ₹2,18,400 = ₹2,96,400 (can be carried forward)
