Few businesses owe every date on this list. Create a free account and VidhiSar works out which are yours, tracks them on your calendar with what each would cost if missed, and reminds you before each one.
These are the dates the law sets. The government extends some of them by notification, often close to the day, and a few depend on facts about your business — your turnover slab, whether you file GST quarterly, when your AGM was held. Check for an extension, and confirm with your CA, before treating a date as final.
