Form 29B & 29C: Audit Reports for Computing MAT and AMT under Income Tax Act
Income Tax Audit Report Under Section 115JB Form 29B computing book profits for companies under Minimum Alternate Tax – MAT.










Income Tax Audit Report Under Section 115JB Form 29B computing book profits for companies under Minimum Alternate Tax - MAT.
Summary: Section 115JB of the Income Tax Act, 1961 introduces the concept of Minimum Alternate Tax (MAT) to ensure that companies reporting high book profits but low taxable income due to deductions still contribute a minimum tax. MAT is levied at 15% (plus surcharge and cess) on a company’s book profits, defined as net profit under the Companies Act with specified adjustments. If tax under regular provisions is less than MAT, companies must pay tax under MAT. The difference between MAT and regular tax can be carried forward for 15 years as MAT credit. Companies liable under MAT must file Form 29B-an audit report certified by a Chartered Accountant-electronically with ITR-6, by the income tax return due date. This form validates the computation of book profit and MAT liability and ensures compliance.
Section 115JC introduces Alternate Minimum Tax (AMT) for non-corporate taxpayers such as individuals, HUFs, partnerships, LLPs, and AOPs who claim deductions under Chapter VI-A Part C or Section 10AA. These taxpayers must pay AMT at 18.5% (plus surcharge and cess) on adjusted total income if it exceeds regular tax liability. To comply, they must file Form 29C, an audit report certified by a Chartered Accountant. Deductions under Chapter VI-A Part C include sections like 80IA (infrastructure), 80IB (SMEs), 80IC (specified regions), 80JJA (biodegradable waste), and 80JJAA (employment generation), among others. These deductions aim to promote specific economic activities. Filing Form 29B or 29C is crucial for ensuring accurate tax liability under MAT or AMT. Non-filing can lead to disallowance of MAT/AMT credit, penalties, and tax scrutiny. Compliance helps maintain transparency and ensures minimum tax contributions from all eligible taxpayers.
Section 115JB of the Income Tax Act.
Section 115JB of the Income Tax Act, 1961, deals with Minimum Alternate Tax (MAT). This provision ensures that companies which show high profits in their books but pay little or no income tax (due to various exemptions/deductions) still contribute a minimum tax based on their book profits. It ensures that companies (especially those availing many exemptions and deductions) pay a minimum amount of tax to the government.
Why MAT
Some companies report high profits in their books but end up paying zero or very little income tax due to various incentives, exemptions, or deductions. MAT was introduced to bring such zero-tax companies into the tax net.
Under MAT, companies are liable to pay 15% (plus applicable surcharge and cess) on their book profits, even if their actual taxable income is lower or nil.
Applicability of MAT
MAT is applicable to:
- All companies (domestic and foreign)
- If the income tax payable under normal provisions is less than 15% of book profit
Legal Provision:
As per Section 115JB, if a company\'s normal income tax liability is less than 15% of the book profit, then the company must pay 15% of book profit (plus surcharge and cess) as Minimum Alternate Tax.
Current MAT Rate: 15% (plus applicable surcharge and cess)
Book Profit
Book Profit means the net profit as per the Profit and Loss Account (prepared under the Companies Act), adjusted by adding or deducting certain specified items like:
Book Profit = Net profit as per the Profit & Loss Account (prepared under Companies Act)
- Certain specified additions (e.g. income tax, provisions, deferred tax, etc.)
− Certain deductions (e.g. exempt income, depreciation as per books, brought forward losses, etc.)
The effective MAT rate is 15% (plus surcharge and cess) of the book profit.
MAT vs Normal Tax
A domestic company with the following details for FY 2023-24:
Particulars | Amount (₹) |
---|---|
Net profit as per books (P&L A/c) | ₹ 1,00,00,000 |
Total income as per Income Tax provisions | ₹ 20,00,000 |
Tax rate under normal provisions | 25% |
MAT rate (as per Section 115JB) | 15% |
Tax Payable under Normal Provisions
Calculation | Amount (₹) |
---|---|
Income as per Income Tax | ₹ 20,00,000 |
Tax @25% | ₹ 5,00,000 |
Add: Cess @4% | ₹ 20,000 |
Total Tax (Normal Provisions) | ₹ 5,20,000 |
Tax Payable under MAT Provisions
Calculation | Amount (₹) |
---|---|
Book Profit as per books | ₹ 1,00,00,000 |
MAT @15% | ₹ 15,00,000 |
Add: Cess @4% | ₹ 60,000 |
Total MAT Payable | ₹ 15,60,000 |
Final Tax Liability (Higher of the Two)
Option | Tax Payable (₹) |
---|---|
Normal Tax | ₹ 5,20,000 |
MAT | ₹ 15,60,000 |
Tax Payable (Higher) | ₹ 15,60,000 |
So, the company must pay ₹ 15.60 lakh under MAT instead of ₹ 5.20 lakh under normal provisions.
MAT Credit
If a company pays MAT, the excess of MAT over normal tax can be carried forward for 15 years and set off in future years when regular tax becomes more than MAT.
Example:
- MAT paid: ₹15,90,000
- Normal tax: ₹5,00,000
- MAT Credit = ₹10,90,000
This MAT credit can be used in future years to reduce tax liability.
Exemptions from MAT
MAT is not applicable to:
- Companies opting for Section 115BAA / 115BAB (new tax regimes for domestic companies)
- Certain foreign companies (in cases where income is not liable to tax under DTAA)
Audit Report Form 29B

Note: Corporate taxpayers are covered under MAT (Minimum Alternate Tax) under Section 115JB, not AMT.
Computation of Adjusted Total Income (ATI)
The Adjusted Total Income is computed as:
ATI = Total Income (before AMT provisions) + Deductions claimed under Section 10AA and Chapter VI-A (Part C)
Once ATI is computed, AMT is calculated as:
AMT = 18.5% of ATI + Surcharge + Health & Education Cess
If this amount is higher than the regular tax, then AMT becomes payable.
example to understand AMT (Alternate Minimum Tax) under Section 115JC to 115JF of the Income Tax Act, applicable mainly to non-corporate taxpayers (like LLPs, individuals, HUFs, AOPs, etc.) who claim certain deductions under Chapter VI-A or Section 10AA.
Example: AMT vs Regular Tax - LLP Case
Taxpayer: ABC LLP
Assessment Year: 2024-25
Total Income before deductions (as per normal provisions): ₹60,00,000
Deduction claimed under Section 10AA: ₹30,00,000
Taxable Income after deduction = ₹30,00,000
Step 1: Calculate Regular Tax
Tax on ₹30,00,000 (as per slab for LLPs @30%) = ₹9,00,000
Add Cess @ 4% = ₹36,000
Total Tax = ₹9,36,000
Step 2: Calculate AMT (Alternate Minimum Tax)
Adjusted Total Income = Total income before deduction = ₹60,00,000
AMT rate = 18.5%
Tax = 18.5% of ₹60,00,000 = ₹11,10,000
Add Cess @ 4% = ₹44,400
Total AMT Payable = ₹11,54,400
Step 3: Compare
Tax Type | Amount Payable |
---|---|
Regular Tax | ₹9,36,000 |
AMT | ₹11,54,400 |
Since AMT is higher, the LLP must pay ₹11,54,400.
Example: AMT Applicability for an Individual
Assessee: Mr. Rajesh
Assessment Year: 2024-25
Age: 45 years (not a senior citizen)
Total income before deduction: ₹45,00,000
Deduction claimed under Section 80-QQB (royalty on books): ₹20,00,000
Taxable income after deduction: ₹25,00,000
Step 1: Calculate Regular Tax
Income = ₹25,00,000
- ₹2,50,000 to ₹5,00,000 @ 5% = ₹12,500
- ₹5,00,001 to ₹10,00,000 @ 20% = ₹1,00,000
- ₹10,00,001 to ₹25,00,000 @ 30% = ₹4,50,000
Total = ₹5,62,500 - Health & Education Cess @ 4% = ₹22,500
Regular Tax = ₹5,85,000
Step 2: Calculate AMT
Since Mr. Rajesh claimed deduction under Section 80QQB, AMT provisions apply.
Adjusted Total Income = ₹45,00,000
AMT Rate = 18.5%
Tax = ₹8,32,500
- Cess @ 4% = ₹33,300
AMT Payable = ₹8,65,800
Step 3: Compare
Type of Tax | Amount |
---|---|
Regular Tax | ₹5,85,000 |
AMT Payable | ₹8,65,800 |
Since AMT is higher, Mr. Rajesh must pay ₹8,65,800 as tax.
AMT Credit:
The excess of AMT over regular tax (₹2,18,400) can be carried forward for up to 15 assessment years, and adjusted when regular income tax exceeds AMT in future.
Due Date for Filing Form 29C
Form 29C must be:
- Filed electronically, and
- Submitted on or before the due date of filing the Income Tax Return under Section 139(1), i.e., 31st October of the assessment year (for audit cases).
Consequences of Non-Compliance
Failure to file Form 29C may result in:
- Disallowance of deductions under Section 10AA or Chapter VI-A,
- Additional tax liability,
- Penalty under Section 271J for incorrect certification,
- Notices and assessments under scrutiny.
Conclusion
Form 29C is a vital audit certification for non-corporate taxpayers availing significant deductions and Form 29B a vital audit certification for corporate taxpayers availing significant deductions. It ensures compliance with Section 115JB & Section 115JB provisions and prevents tax avoidance through excessive deduction claims.
