Businesses and professionals subject to tax audit, and all companies.

Do extensions change this date?
They can. CBDT and CBIC notify extensions from time to time, usually close to the deadline. The date shown here is the statutory one; inside Taxlabs the effective date is used, with any notified extension already applied.
Statutory dates as at the date of publication. Extensions notified after publication are not reflected on this page. This is general information, not advice on your specific filing.
