Month 9 of 12 · Q3 (October – December)
Compliance due dates: December 2026
December carries six filings: the recurring five plus the GST annual return on the 31st.
The annual return reconciles a full year of monthly filings, so December's real work is the twelve months of GSTR-1 and GSTR-3B behind it rather than the single form in front.

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.
