Alternative Minimum Tax (AMT) in India: A Complete Guide with Case Studies

Introduction

The Indian tax system provides various deductions, exemptions, and incentives to encourage businesses and individuals to invest, donate, or engage in specific activities. While these provisions reduce tax liability legally, some high-income individuals and businesses end up paying little to no tax despite earning significant profits.

To ensure fair taxation, the government introduced Alternative Minimum Tax (AMT) under Sections 115JC to 115JF of the Income Tax Act, 1961. AMT ensures that taxpayers benefiting from tax deductions still contribute a minimum amount as tax, similar to Minimum Alternative Tax (MAT), but for non-corporate taxpayers.

Key Highlights of AMT

✔ AMT applies to individuals, Hindu Undivided Families (HUFs), partnerships, LLPs, and other non-corporate entities.
✔ Taxpayers using deductions under Sections 10AA, 35AD, 80H to 80RRB must pay AMT.
✔ AMT is calculated at 18.5% of adjusted total income, plus surcharge and cess.
✔ AMT Credit allows excess tax paid to be adjusted in future years.
✔ Individuals with taxable income below ₹20 lakh are exempt from AMT.

What is Alternative Minimum Tax (AMT)?

Alternative Minimum Tax (AMT) is a special tax provision designed to prevent excessive tax avoidance by individuals and businesses using various deductions and incentives.

Before AMT was introduced, some high-income professionals and businesses paid little or no tax by claiming 100% deductions under sections like:

• Section 10AA (SEZ Benefits) – Businesses operating in Special Economic Zones (SEZs) could claim full tax exemption.
• Section 35AD (Capital Expenditure Benefits) – Allowed businesses to fully deduct capital expenses, reducing taxable income to zero.
• Section 80H to 80RRB (Incentives for Export, R&D, and Donations) – Some taxpayers structured income to claim maximum deductions and avoid tax completely.

To counter this, AMT was introduced to ensure that these taxpayers pay a minimum tax, regardless of deductions claimed.

Who Needs to Pay AMT?

AMT applies to non-corporate taxpayers, including:

✔ Individuals and Hindu Undivided Families (HUFs) – If claiming specified deductions under Sections 10AA, 35AD, or 80H to 80RRB.
✔ Partnership firms and LLPs – If they claim deductions reducing their taxable income significantly.
✔ Association of Persons (AOPs) and Body of Individuals (BOIs) – If using tax incentives to lower tax liability.

Who is Exempt from AMT?

Some individuals and businesses are not required to pay AMT, including:

✔ Individuals and HUFs with taxable income below ₹20 lakh – Small taxpayers are protected from AMT.
✔ Companies – They are governed by Minimum Alternative Tax (MAT), not AMT.
✔ Entities not claiming deductions under Sections 10AA, 35AD, or Chapter VI-A – If no special deductions are used, AMT does not apply.

How is AMT Calculated?

The formula for AMT calculation is:

AMT = 18.5% of Adjusted Total Income + Surcharge + Cess

Example Calculation

Let’s say XYZ LLP has the following details:

• Total Income (Before Deductions) = ₹5 crore
• Deductions Claimed (Under Section 10AA & 80HHE) = ₹3 crore
• Taxable Income (After Deductions) = ₹2 crore

Normal Tax Calculation

If the LLP follows the regular tax regime:
✔ 30% of ₹2 crore = ₹60 lakh (Normal Tax Payable)

AMT Calculation

✔ Adjusted Total Income = ₹5 crore (Adding Back Deductions)
✔ AMT = 18.5% of ₹5 crore = ₹92.5 lakh (Before Surcharge & Cess)

Since AMT is higher than normal tax, the LLP must pay ₹92.5 lakh instead of ₹60 lakh.

This example shows how AMT ensures fair taxation despite deductions.

Case Study: How AMT Affects a Professional Firm

ABC & Co., a law consultancy firm, earns ₹1.5 crore annually. To minimize tax, they claim deductions under Section 35AD (Capital Expenditure Benefits) and 80RRB (Royalty Income Exemptions), reducing their taxable income to ₹50 lakh.

Normal Tax Calculation

✔ 30% of ₹50 lakh = ₹15 lakh tax payable

AMT Calculation

✔ Adjusted Total Income = ₹1.5 crore
✔ AMT = 18.5% of ₹1.5 crore = ₹27.75 lakh

Since AMT is higher than normal tax, the firm must pay ₹27.75 lakh instead of ₹15 lakh.

This case shows how AMT prevents high-income professionals from avoiding tax using deductions.

How AMT Credit Works

If a taxpayer pays AMT instead of normal tax, the extra tax paid (AMT - Normal Tax) can be carried forward for 15 years. This credit can be used to offset future tax liabilities when normal tax exceeds AMT.

For example, if an individual pays ₹10 lakh as AMT but their normal tax was ₹7 lakh, the extra ₹3 lakh can be carried forward for future tax adjustments.

Strategies to Reduce AMT Liability

✔ Managing Deductions Smartly – Spreading deductions over multiple years prevents excessive adjustments to adjusted total income.
✔ Utilizing AMT Credit Efficiently – Tracking AMT credit balance and using it in years when normal tax exceeds AMT.
✔ Restructuring Investments – Investing in government-approved tax-saving schemes to reduce AMT impact.
✔ Tax Planning with Professionals – Consulting tax experts to optimize tax strategies and avoid unexpected AMT liabilities.

The Future of AMT in India

AMT has undergone various changes:

✔ Exemption for Small Taxpayers – Income below ₹20 lakh is now exempt.
✔ Simplification of Tax Laws – Discussions on phasing out AMT as India moves towards a simpler direct tax code.
✔ Possible AMT Rate Reduction – Future budgets may reduce AMT rates to ease business taxation.

The government continuously reviews AMT to balance tax collection and economic growth.
