Corporate income tax is one of the most important compliance responsibilities for companies operating in India. Whether you run a private limited company, startup, manufacturing business, foreign subsidiary, or listed company, understanding how corporate taxation works can directly impact profitability, cash flow, compliance costs, and long-term business growth. With the implementation of the Income-tax Act, 2025 and the latest amendments introduced through the Finance Act, 2026, businesses now have multiple taxation options. Companies can choose between the traditional tax regime with deductions and incentives or opt for concessional tax regimes under Section 200 and Section 201 that offer lower tax rates with simplified compliance requirements. For many business owners, the challenge is not paying tax. The challenge is understanding which regime to choose, how tax is calculated, what deductions remain available, and how to avoid costly penalties. This guide explains corporate income tax in India for FY 2026-27 in a practical and easy-to-understand manner while covering tax rates, calculations, return filing requirements, compliance obligations, tax planning opportunities, and recent legislative changes.
What is Corporate Income Tax?
Corporate income tax is a direct tax imposed on the profits earned by companies during a financial year. Unlike individual taxation, corporate taxation follows a separate framework that applies specifically to incorporated entities. The tax is calculated on the taxable income of the company after allowing eligible business expenses and deductions under the Income-tax Act.
A company earning profits in India is generally required to:
- Calculate taxable income
- Pay advance tax
- Deduct and deposit TDS where applicable
- File annual income tax returns
- Comply with tax audit requirements
The amount payable depends on factors such as turnover, business structure, tax regime selection, and eligibility for deductions or incentives.
Types of Companies Covered Under Corporate Income Tax
Corporate taxation applies differently to domestic and foreign companies.
| Company Type | Tax Treatment |
|---|---|
| Domestic Company | Taxed on Global Income |
| Foreign Company | Taxed Only on Income Arising in India |
| Private Limited Company | Subject to Corporate Tax Provisions |
| Public Limited Company | Subject to Corporate Tax Provisions |
| Startup Company | May Qualify for Specific Incentives |
| Manufacturing Company | Eligible for Concessional Tax Regimes |
A domestic company is generally incorporated in India and is taxed on worldwide income. A foreign company is taxed only on income earned or received in India, subject to applicable Double Taxation Avoidance Agreements (DTAA).
Corporate Tax Regimes in India
One of the most important decisions for any company is selecting the appropriate tax regime. India currently offers two broad corporate taxation frameworks.
Old Corporate Tax Regime
The traditional regime allows businesses to claim deductions, incentives, depreciation benefits, and various tax exemptions. This regime remains relevant for companies that make substantial investments and rely heavily on tax deductions.
Concessional Corporate Tax Regime
The concessional regime offers lower tax rates but removes most deductions and exemptions. Many businesses prefer this option because of its simplicity and predictable tax liability.
Corporate Tax Rate in India for FY 2026-27
The corporate tax rate depends on the company’s turnover and chosen tax regime.
Domestic Company Tax Rates
| Tax Regime | Base Tax Rate | Effective Tax Rate |
|---|---|---|
| Old Regime (Turnover ≤ ₹400 Cr) | 25% | Up to 29.12% |
| Old Regime (Turnover > ₹400 Cr) | 30% | Up to 34.94% |
| Section 200 Regime | 22% | 25.168% |
| Section 201 Manufacturing Regime | 15% | 17.16% |
The effective rate includes surcharge and health & education cess.
Section 200 Corporate Tax Regime Explained
Section 200, previously known as Section 115 BAA, allows domestic companies to pay tax at a concessional rate of 22%. The regime was introduced to improve India’s competitiveness and simplify corporate taxation.
Companies opting for this regime:
- Pay lower taxes
- Cannot claim most deductions
- Are exempt from MAT
- Must file the option within prescribed timelines
For businesses that do not rely heavily on tax incentives, Section 200 often results in significant tax savings.
Section 201 Corporate Tax Regime for Manufacturing Companies
Section 201 is specifically designed for eligible manufacturing companies. The provision offers a 15% base tax rate, making it one of the lowest corporate tax rates available globally.
Companies qualifying under Section 201 benefit from:
- Reduced tax burden
- Simplified compliance
- No MAT liability
However, strict eligibility conditions apply, and companies must carefully evaluate whether they meet the prescribed criteria.
How Corporate Income Tax is Calculated
Corporate tax calculation begins with accounting profits and then adjusts those profits according to tax provisions.
Corporate Tax Calculation Formula
| Component | Amount |
|---|---|
| Revenue | ₹X |
| Less: Business Expenses | ₹X |
| Less: Eligible Deductions | ₹X |
| Taxable Income | ₹X |
| Tax Rate Applied | Applicable Rate |
| Add: Surcharge | As Applicable |
| Add: Health & Education Cess | 4% |
| Final Tax Liability | Total Tax Payable |
Example: Private Limited Company Tax Calculation
Consider a private limited company with annual revenue of ₹15 crore.
| Particulars | Amount |
|---|---|
| Revenue | ₹15 Crore |
| Operating Expenses | ₹11.5 Crore |
| Deductions | ₹50 Lakh |
| Taxable Income | ₹3 Crore |
If the company remains under the old regime, tax will be calculated according to applicable slabs and surcharge rates. This example highlights why selecting the right tax regime can significantly affect overall tax liability.
Corporate Tax Return Filing for Companies
Every company registered under the Companies Act is generally required to file an income tax return. Even companies with no business activity must often comply with filing requirements.
Applicable Return Forms
| Return Form | Applicability |
|---|---|
| ITR-6 | Most Companies |
| ITR-7 | Exempt Entities and Specific Organizations |
Corporate Tax Filing Due Dates FY 2026-27
| Compliance | Due Date |
|---|---|
| Tax Audit Report | 30 September |
| Income Tax Return (Audited) | 31 October |
| Transfer Pricing Cases | 30 November |
| Belated Return | 31 December |
Missing these deadlines may result in penalties and interest.
Corporate Tax Compliance Calendar
Corporate taxation is not limited to filing an annual return. Businesses must monitor compliance throughout the year.
Key areas include:
- Advance tax payments
- TDS compliance
- Tax audit reporting
- Return filing
- GST reconciliation
A structured compliance calendar helps businesses avoid penalties and maintain financial discipline.
Corporate Tax Deductions Available to Companies
Companies under the old regime may claim several deductions to reduce taxable income.
| Deduction Category | Examples |
|---|---|
| Business Expenses | Salaries, Rent, Utilities |
| Depreciation | Plant and Machinery |
| Interest Expenses | Business Loans |
| R&D Expenses | Research Activities |
| Employee Benefits | PF and Gratuity Contributions |
Corporate Tax Planning Strategies
Effective tax planning focuses on minimizing tax liability while maintaining full compliance.
Businesses often benefit from:
- Selecting the correct tax regime
- Optimizing depreciation claims
- Structuring capital expenditure efficiently
- Utilizing startup incentives
- Managing MAT credits strategically
Proper planning can improve cash flow without increasing compliance risks.
Minimum Alternate Tax (MAT) Explained
Minimum Alternate Tax ensures that profitable companies pay a minimum amount of tax even when deductions significantly reduce taxable income. Recent changes under the Finance Act 2026 have altered the treatment of MAT credits and their utilization. Companies evaluating a shift to concessional tax regimes should carefully assess the impact on accumulated MAT credits.
Corporate Tax for Startups
SPIRIT-recognized startups may qualify for tax benefits under Section 140. Eligible startups can claim a 100% tax holiday on profits for three consecutive years within the first ten years of incorporation, subject to prescribed conditions. For high-growth startups, this incentive can significantly reduce early-stage tax costs.
Common Corporate Tax Mistakes Businesses Should Avoid
Many companies pay unnecessary taxes or face notices because of avoidable mistakes. Common issues include incorrect tax regime selection, delayed audit reporting, missed advance tax payments, non-compliance with TDS obligations, and failure to reconcile GST and income tax records. Businesses should review tax positions periodically rather than waiting until year-end.
