Context comes first

Useful dates.
Clear boundaries.

This is a limited public planning resource, not your personalised filing schedule. Your entity, registration, transactions and jurisdiction can change what applies.

Discuss your requirements
What is covered today?

Selected GSTR-1 dates and the AY 2026–27 audit/ITR extension. TDS/TCS, other GST returns and company/LLP due dates are not yet included. New or empty months do not mean that no obligations exist. Event-based company filings require your own relevant dates.

How are dates sourced?

Entries link to official guidance or notifications. A standard schedule and a notification-backed extension have different labels. Source checks do not establish that every subsequent or local change has been covered.

Will calendar exports update automatically?

No. Downloads and Google Calendar links create a snapshot. Return here and check the official source for extensions. Your calendar controls reminder settings.

Does this track my filing status?

No. “Date passed” describes the calendar date only. We do not collect identifiers, documents or filing records, and cannot tell whether you have filed.

Spotted a change or missing date?

Email Finnvisor Advisory with the form, period and official notification link. Changes need source review before publication.
