Alternative Minimum Tax (AMT): Meaning, Rates, and Rules in India

Alternate Minimum tax (AMT) was introduced in Finance Act, 2012. The idea of introduction of AMT was to collect minimum amount of tax from the taxpayers (other than companies) who claimed various deductions which reduced their tax burden through legitimate means Introduced under Section 115JC section 206 of Income Tax Act 2025), this provision ensures that taxpayers claiming certain profit-linked deductions continue to pay a baseline amount of tax to the government.

AMT is a minimum tax levied on non-corporate taxpayers whose regular tax liability falls below a defined threshold owing to multiple deductions claimed.

The purpose is that the taxpayers pays minimum amount of tax on income earned during the financial year.

In practice, it functions as a parallel tax system. You compute your regular tax alongside your AMT, and where the regular liability is lower than the AMT, the AMT becomes payable instead.

A common question is how AMT differs from MAT (Minimum Alternate Tax). Although both serve the same fundamental objective of ensuring that taxpayers pay a minimum amount of tax despite claiming specified deductions and incentives, they apply to different categories of taxpayers. AMT applies to non-corporate taxpayers, such as individuals, Hindu Undivided Families (HUFs), Limited Liability Partnerships (LLPs), and Associations of Persons (AOPs)whereas, MAT applies only to corporate entities i.e. Companies.

The alternative minimum tax does not apply to every taxpayer. It is applicable to taxpayers who has claimed specific deductions as provided u/s 206 of the Income Tax Act, 2025

The Deductions: The Adjusted Total Income shall be calculated by adding the amount of deductions claimed by the taxpayer as mentioned below

1. Deductions under any section mentioned in Chapter VIII-C of the Act except for section 149; or
2. Deductions for specified capital expenditure businesses under Section 46.

The Threshold: The provision generally does not apply to individuals, HUFs, AOPs, and BOIs whose adjusted total income does not exceed ₹20 lakhs

If an individual or HUF opt for New Tax Regime (Section 202(1)), the provisions of AMT shall not be applicable.

the provisions does not apply to certain Co-operative societies who are taxed u/s 203(5) or u/s 204(2) of the Act.

Tax Planning Note: Regular personal deductions under Section 123 of Income tax Act 2025 / Section 80C of the Tax Act 1961 (such as premiums paid towards an SBI Life insurance policy), Section 126 of Income tax Act 2025 / Section 80D of the Tax Act 1961 or the standard deduction are not impacted by AMT. Consequently, salaried individuals who rely on standard life and health insurance tax-savers do not generally attract AMT provisions.

For taxpayers covered under this provision, computing the liability requires specific rates. The AMT tax rate structure is as follows:

1. Tax is applicable @ 18.5% of your "Adjusted Total Income." .
2. Tax is applicable @ 15% on Co-operative socities
3. Tax is applicable @ 9% for units situated in an International Financial Services Centre (IFSC) that derive income solely in convertible foreign exchange

Determining your exact liability begins with the calculation of your Adjusted Total Income (ATI). The standard formula is set out below:

Regular Taxable Income (after all normal deductions)

(+) Add back: Deductions under any section mentioned in Chapter VIII-C of the Act except for section 149

(+) Add back: Deductions for specified capital expenditure businesses under Section 46 (less the normal depreciation that would otherwise have been allowed)

(=) Result: Adjusted Total Income

Where this Adjusted Total Income exceeds ₹20 Lakhs, the 18.5% rate is applied to arrive at your final AMT liability.

Paying a higher amount on account of AMT provisions does not mean the money is lost permanently. The Income Tax framework extends relief through the AMT Credit mechanism.

The Difference: Where you pay AMT because it exceeds your regular tax, the excess amount (AMT minus regular tax) is retained as your "AMT Credit."

Carry Forward: This accumulated credit may be carried forward for up to 15 assessment years.

Utilisation: The credit becomes useful in subsequent financial years when your regular tax liability exceeds your AMT. It is offset against the regular tax liability, reducing it to the AMT amount for that year.
