A monthly compliance calendar for small businesses

1 October 2026

Most penalties for small businesses come from missing routine due dates. These are the usual recurring dates. Your own list depends on your registrations and turnover, and the government sometimes extends dates, so we confirm them for each client.

Every month

Due date What Applies to
7th Deposit TDS / TCS deducted in the previous month (March: 30 April) Businesses deducting TDS
11th GSTR-1 (outward supplies) Monthly GST filers
15th PF and ESI contributions Employers registered under PF / ESI
20th GSTR-3B and payment of GST Monthly GST filers

Businesses under the GST QRMP scheme file quarterly returns and pay tax monthly, on different dates.

Every quarter

  • TDS / TCS returns: 31 July, 31 October, 31 January and 31 May
  • Advance tax instalments: 15 June, 15 September, 15 December and 15 March

Every year

  • Income tax returns: usually 31 July for individuals and businesses not requiring audit, and 31 October for those requiring audit
  • Tax audit report: before the return due date for audit cases
  • GST annual return: 31 December following the financial year, where applicable
  • ROC annual filings for companies and LLPs: due within set periods after the year end or annual general meeting
