Multi-Regulatory Compliance Calendar — December 2026

December is anchored by the third instalment of advance tax and closes the calendar year with a heavy annual-filing cluster — the GSTR-9/9C annual return and reconciliation statement for FY 2025-26, the SEZ and FEMA Annual Performance Reports, Form FC-3 for foreign company branches, and the NBFC's annual return in NBS-10. It also carries the half-yearly Debenture Trustee security-cover and covenant-compliance certifications, the AIF's NAV-independence and valuation requirement, the AIF's quarterly compliance report to its Trustee, and the InvIT's quarter-end asset valuation. This calendar consolidates every recurring due date across Income Tax, GST, RBI/NBFC, SEBI (AIF, Debenture Trustees, InvITs, REITs), Corporate Law, SEZ/STPI, and FEMA that falls in December 2026.

How We Help

December brings the third advance tax instalment, the GSTR-9/9C annual return and reconciliation cluster for FY 2025-26, half-yearly Debenture Trustee security-cover and covenant certifications, and a year-end run of annual filings across NBFCs (NBS-10), SEZ units, FEMA overseas investment reporting, and foreign company branches — alongside the AIF's NAV, valuation, and Trustee-compliance obligations and the InvIT's quarter-end asset valuation. At Anuj Desai & Associates, we track every one of these obligations against the entity's specific registration category, prepare the filings well ahead of the deadline, and manage the submissions directly with the regulator. If December's filing load is more than your team wants to track in-house, get in touch with our compliance desk.
