Adding the dates to your calendar

  • Google Calendar: download the .ics file, then open Google Calendar on a computer, go to Settings → Import & export → Import, and choose the file.
  • Outlook: open the .ics file, or use File → Open & Export → Import/Export.
  • Apple Calendar (iPhone, Mac): open the downloaded file and choose the calendar to add it to.

Each file holds all-day entries with a reminder three days before. The download follows the areas ticked above. Importing the same file again updates the entries rather than duplicating them in most calendar apps.

Points to note

  • Income-tax Act, 2025: returns and payments for Tax Year 2026-27 use the new forms, such as Form 138 / 140 / 144 for TDS statements and Form 143 for TCS. Returns for FY 2025-26 (AY 2026-27) are filed under the 1961 Act. See the Income Tax Act 2025 guide.
  • ROC dates for AOC-4, MGT-7 and ADT-1 run from the date of the AGM; the dates above assume the AGM is held on 30 September. The ROC due date calendar explains each form.
  • DIR-3 KYC is now filed once every three financial years, by 30 June. Directors whose KYC was up to date under the old yearly system are next due by 30 June 2028, so it does not fall in this period. Check your DIN with the DIN KYC reminder.
  • GST QRMP taxpayers in Delhi file the quarterly GSTR-3B by the 24th; the 22nd applies in the States listed against that entry.
  • State laws such as professional tax and labour welfare fund vary. Delhi does not levy professional tax.
