Section 115JB Tax Calculator (AY 2019-20)
Module A: Introduction & Importance of Section 115JB (AY 2019-20)
Section 115JB of the Income Tax Act, 1961, commonly known as the Minimum Alternate Tax (MAT) provision, was introduced to ensure that companies paying dividends to shareholders contribute a minimum amount of tax to the exchequer. For Assessment Year 2019-20, this provision plays a crucial role in preventing tax avoidance by companies that show book profits but pay little or no tax due to various exemptions, deductions, and incentives.
The key objectives of Section 115JB include:
- Ensuring minimum tax payment by profit-making companies
- Preventing tax avoidance through excessive use of exemptions
- Maintaining fairness in the tax system
- Generating stable revenue for the government
For AY 2019-20, the MAT rate was 15% for domestic companies and 18% for foreign companies. The provision applies when the tax payable under normal provisions is less than 15%/18% of the book profit. Companies must calculate their tax liability under both normal provisions and MAT provisions, then pay the higher of the two amounts.

Module C: Formula & Methodology
The MAT calculation under Section 115JB follows a specific formula:
MAT = (Adjusted Book Profit × Applicable Rate) + Surcharge + Cess
Step 1: Calculate Book Profit
Book Profit = Net Profit as per P&L Account + Adjustments
Step 2: Make Required Additions
The following items must be added back to the book profit:
- Income tax paid/provisioned (including MAT)
- Dividend distributed (if not allowed as deduction)
- Provision for bad and doubtful debts
- Provision for diminution in asset value
- Provision for proposed dividend
- Amount carried to reserves
- Deferred tax and provision thereof
- Amount set aside for corporate social responsibility
Step 3: Allow Permissible Deductions
The following items can be deducted from the book profit:
- Amount withdrawn from reserves (if credited to P&L)
- Income exempt under sections 10, 11, or 12
- Depreciation (other than revaluation)
- Amount of brought forward loss/unabsorbed depreciation (if set off)
Step 4: Apply Tax Rate
For AY 2019-20:
- Domestic companies: 15% of adjusted book profit
- Foreign companies: 18% of adjusted book profit
Step 5: Add Surcharge and Cess
The MAT amount is increased by:
- Surcharge: 7% if taxable income > ₹1 crore, 12% if > ₹10 crore
- Health & Education Cess: 4% of (MAT + Surcharge)

Module G: Interactive FAQ
What is the difference between normal tax and MAT under Section 115JB?
Normal tax is calculated on taxable income as per Income Tax Act provisions, considering all exemptions, deductions, and incentives. MAT under Section 115JB is calculated on book profit (as per financial statements) with specific adjustments, at a flat rate of 15% (domestic) or 18% (foreign) for AY 2019-20.
The key differences are:
- Base: Taxable income vs. Book profit
- Rate: Progressive rates vs. Flat 15%/18%
- Adjustments: Different addition/deduction rules
- Purpose: Regular taxation vs. Minimum tax guarantee
Companies must pay the higher of the two amounts calculated under normal provisions and MAT provisions.
How are dividend income and capital gains treated under Section 115JB?
Under Section 115JB for AY 2019-20:
- Dividend Income:
- Dividend received from domestic companies is included in book profit
- Dividend received from foreign companies is also included
- Dividend distributed by the company is added back to book profit
- Dividend Distribution Tax (DDT) was applicable at 15% for AY 2019-20
- Capital Gains:
- Both short-term and long-term capital gains are included in book profit
- No special treatment – treated as part of regular book profit
- Exempt capital gains (like from STT-paid equity shares) may be deducted if properly documented
Important note: The treatment changed significantly in subsequent years with the abolition of DDT in 2020. For AY 2019-20, the traditional DDT regime was still in effect.
What are the common mistakes companies make in MAT calculations?
Based on tax audit findings and assessments, these are frequent errors:
- Incorrect Book Profit: Using net profit instead of properly adjusted book profit as per Section 115JB(2)
- Missing Additions: Forgetting to add back items like income tax provision, CSR expenses, or proposed dividends
- Improper Deductions: Claiming deductions not permitted under MAT provisions (like certain exempt incomes)
- Wrong Rate Application: Using incorrect tax rates (15% vs 18%) based on company status
- Surcharge Errors: Misapplying surcharge thresholds or rates
- Cess Miscalculation: Forgetting to add Health & Education Cess at 4%
- Documentation Gaps: Lack of proper working papers to support adjustments
- Timing Issues: Not considering the relevant previous year for AY 2019-20 (FY 2018-19)
- Foreign Company Status: Incorrect classification of foreign company status affecting the applicable rate
- Loss Set-off: Improper utilization of brought forward losses or unabsorbed depreciation
These errors can lead to underpayment of MAT, attracting interest and penalties. Regular tax health checks by professionals can help avoid such mistakes.
Can MAT paid be carried forward or set off against future tax liabilities?
Yes, one of the most important features of MAT is the credit mechanism:
- MAT Credit: The excess of MAT paid over normal tax can be carried forward for 15 assessment years
- Set-off Rules: This credit can be set off against regular tax payable in subsequent years when normal tax exceeds MAT
- No Interest: Unlike tax refunds, MAT credit doesn’t earn any interest
- Documentation: Must be properly disclosed in tax audit reports and return of income
- Utilization Order: Should be utilized in the order of assessment years (FIFO basis)
Example: If a company pays MAT of ₹50 lakh in AY 2019-20 when normal tax was ₹30 lakh, it gets MAT credit of ₹20 lakh. This can be used to reduce tax payable in any of the next 15 years when normal tax exceeds MAT.
Important: MAT credit cannot be transferred in cases of amalgamation/demergers unless specific conditions are met as per Section 72A/72AA.
How does Section 115JB interact with other tax provisions like Section 115BAA?
Section 115JB (MAT) interacts with several other tax provisions, creating complex compliance scenarios:
With Section 115BA (Manufacturing Companies):
- Companies opting for 115BA (25% tax rate) are still subject to MAT
- MAT rate remains 15% even if normal rate is reduced to 25%
- Need to compare both liabilities and pay the higher amount
With Section 115BAA (New Manufacturing Regime):
- Introduced in 2019, this section offers 15% tax rate for new manufacturing companies
- Companies opting for 115BAA are exempt from MAT as per Section 115JB(5A)
- This creates a significant advantage for eligible companies
With Section 115JC (AMT for Non-Corporates):
- Similar to MAT but applies to non-corporate taxpayers
- Different adjustment rules and tax rates
- No direct interaction but similar conceptual framework
With Transfer Pricing Provisions:
- Transfer pricing adjustments may affect book profit
- Need to ensure consistency between TP documentation and MAT calculations
- Secondary adjustments may require MAT recomputation
For AY 2019-20, Section 115BAA wasn’t yet widely applicable as it was introduced later in the year. Most companies still needed to comply with MAT provisions unless they qualified for specific exemptions.
What are the compliance requirements and due dates for MAT payments?
The compliance framework for MAT under Section 115JB includes:
Payment Due Dates:
- Advance Tax:
- 15% by 15 June
- 45% by 15 September
- 75% by 15 December
- 100% by 15 March
- Final Payment: Any balance by 31 March (for companies not liable for advance tax)
Return Filing:
- Due date: 30 September of assessment year (30 November if tax audit applicable)
- Form: ITR-6 for companies
- Mandatory disclosure: MAT computation in Schedule MAT
Tax Audit Requirements:

- Form 3CD requires detailed MAT computation disclosure
- Clause 20B specifically deals with MAT reporting
Documentation:

- Interest under Section 234C (1% per month for deferment of advance tax)
- Penalty under Section 271(1)(c) for concealment (100-300% of tax sought to be evaded)
- Prosecution under Section 276C for willful attempt to evade tax
For AY 2019-20, the due dates were particularly important as it was the last year before significant changes in corporate tax rates and MAT provisions in subsequent budgets.
Are there any exemptions or reliefs available under Section 115JB?

- Companies opting for Section 115BAA (new manufacturing regime) from AY 2020-21 onwards
- Income from life insurance business (Section 115B)
- Shipping companies (Section 115V to 115VZC)

- Reliefs are often subject to strict conditions and documentation requirements
