Month 2 of 12 · Q1 (April – June)

Compliance due dates: May 2026

May carries only the five recurring obligations — TDS deposit, the two GST returns, PF and ESI, and professional tax.

It is the quietest kind of month on paper, and the one where annual work is most usefully started. Nothing dated here competes for attention, which is rarely true again until the winter.

These are the obligations we track for the standard statutory position. Sector rules, state-level professional tax and one-off events can add to them, and extensions can move a date. Ask us before relying on this for a filing.
