Minimum Tax for Profitable Companies

Section 115JB (MAT) Simplified

Sometimes companies report large profits in their books but pay zero income tax by claiming various exemptions. The government introduced Section 115JB (Minimum Alternate Tax) to ensure these companies contribute a fair share.

The Simple Logic: If you are profitable enough to show a profit to your shareholders, you are profitable enough to pay at least a 15% minimum tax.

1. How is it Calculated?

Every year, a company calculates tax in two ways and pays the higher of the two:

  • Normal Tax: Tax on income after all deductions.
  • MAT: 15% tax on your "Book Profit."

2. What is "Book Profit"?

This is the profit shown in your Profit & Loss statement, but adjusted for the tax office. You generally:

  • Add Back: Income tax provisions, dividends, and money moved to reserves.
  • Subtract: Specific tax-free income and certain past business losses.

3. The MAT Credit (Your Tax Refund)

If you pay MAT because it was higher than your normal tax, that "extra" payment isn't lost. It is stored as a credit that you can use to reduce your tax in the future when your normal tax is higher than MAT. You can carry this credit forward for 15 years.
