How to File Company Income Tax Return in India: Step-by-Step Guide

What is Corporate Tax Return Filing?

Corporate tax filing is the formal declaration of a company’s income, expenses, deductions, and tax liabilities to the Income Tax Department of India for a specific Financial Year (FY). Unlike individual filers, every corporate entity registered under the Companies Act, 2013 (or previous acts)  must file an annual tax return using designated forms—primarily  ITR-6  or  ITR-7.

Which Form Should Your Company File?

Selecting the right tax form is the first step toward error-free compliance:

• ITR-6:  Applicable to all companies except those claiming exemption under Section 11 (income from charitable or religious trusts). Private limited, public limited, and OPCs use ITR-6
• ITR-7:  Applicable to companies and entities required to furnish returns under Sections 139(4A), 139(4B), 139(4C), or 139(4D) (e.g., trusts, political parties, research associations, and scientific institutions).

Important Company Tax Return Due Dates in India

Missing statutory deadlines results in penalties, mandatory interest under Sections 234A, 234B, and 234C, and the loss of the right to carry forward corporate losses. Knowing what the due date to file company income tax return in India  helps maintain institutional compliance.

Key Documents Required for Company ITR Filing

Before initiating the online return filing process, keep the following documentation organized. Having these records ready accelerates the filing workflow and reduces verification errors.

• Audited Financial Statements:  Profit & Loss Statement, Balance Sheet, Notes to Accounts, and Auditor’s Report.
• Tax Audit Report:  Form 3CA and Form 3CD (where tax audit under Section 44AB applies).
• Form 26AS & Annual Information Statement (AIS):  Tax Credit Statement showing TDS deducted, TCS collected, and advance tax payments.
• Class 3 Digital Signature Certificate (DSC):  Registered on the e-filing portal under the Director’s PAN.
• Incorporation Documents:  Corporate Identification Number (CIN), Company PAN, and registered address details.
• Bank Statements:  Complete details of all active company bank accounts operating during the financial year.
• Form 29B:  Report for computation of Minimum Alternate Tax (MAT) under Section 115JB (if applicable).

Tax Audit Under Section 44AB for Companies

A crucial component of corporate tax filing in India is assessing whether your company requires a statutory tax audit.

When is a Tax Audit Mandatory?

Under  Section 44AB of the Income Tax Act , a company must have its accounts audited by a practicing Chartered Accountant if:

1. Business Turnover Exceeds ₹1 Crore:  Applies to corporate entities operating primarily in cash.
2. Business Turnover Exceeds ₹10 Crore:  Applies when digital transactions account for  95% or more  of total receipts and payments.

Corporate Tax Rates Overview

Companies can choose between standard taxation rules or concessional corporate tax regimes:

• Section 115BAA:  Allows domestic companies to pay a concessional base tax rate of  22%  (effective tax rate approx. 25.17% including surcharge and cess), provided they forego specific incentives/deductions and do not claim MAT benefits.
• Standard Tax Regime:  25% base rate for domestic companies with turnover up to ₹400 crore in the prior year, or 30% for larger entities, subject to Minimum Alternate Tax (MAT) under Section 115JB.
