How do I file an income tax return for my company in India?
A company files ITR-6 on the income tax e-filing portal every year, profit or loss, signed with a director's Digital Signature Certificate. For the year to 31 March 2026, audited companies have until 21 November 2026 (extended from 31 October), with the tax audit report due by 21 October. In order: close the books and finish the statutory audit; if a tax audit applies, the CA files that report first; work out the tax, where most startups pay 22% under section 115BAA plus surcharge and 4% cess, opted into through Form 10-IC by the due date; pay any balance by challan; then file ITR-6 and sign it with the DSC. A DPIIT startup holding an 80-IAC certificate claims its tax holiday in this return. Income from 1 April 2026 falls under the Income-tax Act 2025, where the same holiday is section 140.
