Income Tax Return (ITR) filing for companies is a mandatory compliance under the Income Tax Act, 1961, requiring all domestic and foreign companies operating in India to report their annual income, deductions, and taxes paid. The return includes details of profits or losses from business operations, capital gains, income from other sources, and deductions claimed under various sections of the Act. Companies must file the appropriate ITR form, such as ITR-6, along with audited financial statements and Tax Audit Reports (if applicable). Filing deadlines vary based on whether the company is required to undergo tax audit. Timely and accurate filing ensures compliance, prevents penalties, and allows companies to carry forward losses for set-off in future years. Professional assistance is recommended for preparing financial statements, reconciling accounts, applying deductions, and e-filing through the Income Tax Department portal. Proper compliance strengthens corporate governance, ensures legal adherence, and provides transparency in financial operations, thereby minimizing the risk of scrutiny or penalties from tax authorities.
