Quick Answer
This compliance calendar for India business covers every major 2026 deadline – corporate/ROC filings, tax, GST, IP renewals, and DPDP Act milestones. Each category links to a full guide. Bookmark this page and check the “last updated” date. Missing a deadline triggers penalties, so track these dates against your entity type.
Indian businesses face filing deadlines across five regulators: the Ministry of Corporate Affairs (MCA), the Income Tax Department, the GST authorities, the patent and trademark registries, and now the Data Protection Board under the Digital Personal Data Protection Act, 2023. Miss one, and the penalty follows fast. At Altacit Global, we built this calendar as a single lookup page so you can find any 2026 deadline in seconds and go straight to the full guide for the detail.
What are the corporate and ROC filing deadlines for 2026?
These deadlines apply to companies and directors registered with the MCA. Dates assume a financial year ending March 31, 2026, and an AGM held within statutory limits. See our complete corporate compliance guide for entity-specific variations.
Filing | Form | Deadline (2026) | Applies to |
DIN KYC | DIR-3 KYC | September 30, 2026 | Every director with a DIN |
Annual General Meeting | – | September 30, 2026 | Companies (within 6 months of FY end) |
Financial Statements | AOC-4 | October 30, 2026 (within 30 days of AGM) | All companies |
Annual Return | MGT-7 / MGT-7A | November 29, 2026 (within 60 days of AGM) | Companies and OPCs |
Directors who miss DIR-3 KYC see their DIN deactivated and pay a ₹5,000 reactivation fee. Late AOC-4 and MGT-7 filings attract ₹100 per day, per form, with no cap.
What are the income tax deadlines for 2026?
India’s healthcare and pharmaceutical sector is governed by a layered set of central statutes, subordinate rules, and regulatory guidelines. Understanding how these instruments interact is foundational to any compliance strategy.These dates apply to companies, LLPs, and individuals with business income. Advance tax runs in four installments across the financial year.
Shortfalls in advance tax attract interest under Sections 234B and 234C. Late ITR filing draws a fee up to ₹5,000 under Section 234F.
What are the GST filing due dates for 2026?
GST due dates for 2026 depend on your turnover and whether you file monthly or under the QRMP scheme. The dates below cover monthly filers. Our GST compliance guide breaks down the QRMP schedule and turnover thresholds.
Return | Purpose | Deadline | Applies to |
GSTR-1 | Outward supplies | 11th of the following month | Monthly filers |
GSTR-3B | Summary return and tax payment | 20th of the following month | Monthly filers |

What are the intellectual property renewal deadlines?
IP deadlines run on the life of each right, not the financial year. Track the anniversary of each filing.
Obligation | Form | Deadline | Applies to |
Trademark Renewal | TM-R | Every 10 years from registration | Registered trademark owners |
Patent Annuity | Form 15 | Annually, from the 3rd year onward | Granted patent holders |
Request for Examination | Form 18 | Within 31 months of priority date | Patent applicants |
Statement of Working | Form 27 | September 30, 2026 (for FY 2025–26) | Every granted patent holder |
A trademark not renewed within the 10-year term can be removed from the register, though a 6-month grace period with a surcharge applies. A patent lapses if the annuity goes unpaid. Failure to file Form 27 can expose a patent to a compulsory license under the Patents Act, 1970.
What are the DPDP Act milestone dates?
The Digital Personal Data Protection Act, 2023 rolls out in phases. The government notified the DPDP Rules in 2026, and obligations take effect on a staggered timeline. These dates apply to any business that processes personal data of individuals in India. Read our DPDP compliance guide for the full obligation set.
Phase | What takes effect | Timeline |
Phase I | Data Protection Board established; definitions and framework in force | On notification (2026) |
Phase II | Consent, notice, and grievance obligations for Data Fiduciaries | ~12 months after notification |
Phase III | Significant Data Fiduciary duties: DPIAs, audits, Data Protection Officer | ~18 months after notification |
Penalties under the DPDP Act reach ₹250 crore for failure to prevent a data breach. Every business handling personal data should map its Phase II and Phase III obligations now, well before the compliance window closes.

Frequently Asked Questions: India Compliance Calendar
Q1: Do these deadlines apply to all business types?
Q2: What happens if a compliance deadline is missed?
The penalty depends on the filing. Missed DIR-3 KYC deactivates the director’s DIN and costs ₹5,000 to reactivate. Late AOC-4 or MGT-7 filings attract ₹100 per day, per form, with no upper limit. Advance tax shortfalls draw interest under Sections 234B and 234C. Late GST returns carry 18% annual interest on unpaid tax plus a late fee. An unrenewed trademark can be removed from the register; an unpaid patent annuity lapses the patent. DPDP breaches can reach ₹250 crore. In short, penalties escalate the longer you wait to file on time, or file immediately once you realize a date has passed.
