March 2026 is the most strategically important compliance month of the financial year, as it marks the closure of FY 2025-26 and the transition to a new regulatory era. The single most critical deadline is March 15, 2026, when the 4th and final instalment of Advance Tax under Section 211 of the Income Tax Act, 1961, falls due — requiring taxpayers to discharge 100% of their estimated tax liability. Businesses opting for presumptive taxation under Sections 44AD/44ADA must also pay their entire advance tax by this date in a single instalment 📋.
Alongside regular monthly GST and TDS obligations, March brings year-end responsibilities including CbC Reporting (Form 3CEAD) for multinational enterprises, Form 67 filing for Foreign Tax Credit claimants, and the deadline for filing Updated Returns for AY 2021-22. Additionally, the MCA has notified the Companies Compliance Facilitation Scheme (CCFS) 2026 vide General Circular No. 01/2026 dated February 24, 2026, offering companies a three-month window starting April 15, 2026, to regularise pending filings at just 10% of accumulated additional fees. Businesses must also note that the proposed Income Tax Act, 2025, along with the Income Tax Rules, 2026, is set to become effective from April 1, 2026, making this the final compliance month under the existing Income Tax Act, 1961 framework.
🚨 Year-End Alert: Final Month Under the Income Tax Act, 1961
March 2026 holds historic significance as the last compliance month governed by the Income Tax Act, 1961. Effective April 1, 2026, the proposed Income Tax Act, 2025, along with the Income Tax Rules, 2026, will come into force (subject to formal notification). While all FY 2025-26 compliance obligations continue under the existing framework, businesses should begin preparing their systems, processes, and teams for the transition. Key areas requiring preparation include updated ITR forms, revised TDS/TCS rate structures, rationalised MAT provisions, and simplified assessment procedures.

Important Notes for Advance Tax Compliance:
Advance Tax is payable by all taxpayers — companies, LLPs, professionals, and individuals — whose estimated tax liability after TDS exceeds Rs. 10,000 in a financial year. Failure to pay adequate advance tax attracts interest under Section 234B (1% per month on shortfall from assessed tax) and Section 234C (1% per month on instalment shortfall). For the 4th instalment, taxpayers must compute 100% of estimated tax liability for FY 2025-26, deduct TDS credits and advance tax already paid, and deposit the balance by March 15. Taxpayers under presumptive taxation schemes (Sections 44AD and 44ADA) who have not paid advance tax in earlier instalments must pay the entire liability in this single instalment ⚡.

March 2026 carries standard monthly GST filings for February 2026 transactions. QRMP taxpayers are in the second month (M2) of Q4 (Jan-Mar 2026), with IFF and PMT-06 obligations continuing. A critical year-end compliance is the deadline for filing Form CMP-02 by taxpayers opting into the Composition Scheme for FY 2026-27. Below are all GST-related due dates:
| Due Date | Purpose (Form) | Period | Description |
|---|---|---|---|
| 10 Mar 2026 | GSTR-7 / GSTR-8 | Feb 2026 | Returns for GST TDS/TCS by deductors and e-commerce operators for tax deducted/collected in February 2026. |

Key Points for GST Year-End in March 2026:
March is the financial year-end, and GST compliance during this month directly impacts annual return preparation. Businesses must ensure complete reconciliation of GSTR-1 and GSTR-3B with their books of accounts before the year closes. Input Tax Credit (ITC) for FY 2025-26 that has not been claimed in GSTR-3B returns filed up to September 2026 will be lost, as per Section 16(4) of the CGST Act; however, the groundwork for ITC reconciliation should begin now. QRMP taxpayers should note that the quarterly GSTR-1 and GSTR-3B for Q4 (Jan-Mar 2026) will be due in April 2026. Taxpayers opting into the Composition Scheme for FY 2026-27 via CMP-02 must also file Form ITC-03 within 60 days (by May 30, 2026) to reverse applicable input tax credits 📌.
Companies Act & LLP Compliance (ROC Filings) – March 2026 🏢
March 2026 is a relatively lean month for mandatory ROC filings. The key development is the notification of CCFS 2026, which offers relief for companies with pending filings. Additionally, companies should focus on closing their FY 2025-26 books and preparing for the upcoming annual compliance cycle.
| Due Date | Purpose (Form) | Authority | Description |
|---|---|---|---|
| 31 Mar 2026 | Financial Year Closure | Companies Act, 2013 | Close of FY 2025-26 for all companies with March year-end. This triggers the annual compliance cycle — statutory audit, Board meetings for financial statement approval, AGM, and subsequent ROC filings. |
| Ongoing | MSME-1 Preparation | MCA/ROC | Companies should begin preparing data for Form MSME-1 (outstanding payments to Micro and Small Enterprises) for H2 FY 2025-26 (Oct 2025 – Mar 2026), which will be due on April 30, 2026. |
🚨 CCFS 2026 – Companies Compliance Facilitation Scheme Notified
The Ministry of Corporate Affairs notified the Companies Compliance Facilitation Scheme, 2026 vide General Circular No. 01/2026 dated February 24, 2026, offering a three-month window (April 15, 2026, to July 15, 2026) for companies to regularise pending statutory filings. Key highlights of CCFS 2026 include:
- Filing Relief: Companies can file overdue forms — including MGT-7, MGT-7A, AOC-4 (all variants), ADT-1, FC-3, FC-4, and legacy forms under the Companies Act, 1956 — by paying normal fees plus only 10% of accumulated additional fees (effectively a 90% waiver).
- Dormancy Option: Inactive companies can apply for dormant status by filing Form MSC-1 at just 50% of the normal filing fee, allowing them to remain registered with minimal future compliance.
- Strike-Off Route: Companies seeking closure can apply for voluntary strike-off via Form STK-2 at 25% of the applicable filing fee.
- Immunity from Prosecution: Companies that complete filings before an adjudication notice is issued, or within 30 days of such notice, will not face penalties under Sections 92 and 137 of the Companies Act, 2013.
Companies that have been struck off, that are under liquidation, or against which action under Section 7 of the Insolvency and Bankruptcy Code has been initiated, are not eligible. Post July 15, 2026, MCA has indicated that strict enforcement action will follow against companies that remain in default. Businesses with long-pending non-compliances should use March to compile their records and prepare for filing once the scheme window opens on April 15, 2026 🎯.
Labour Law Compliance (EPF & ESI) – March 2026 👷
Employers must ensure the timely deposit of EPF and ESI contributions for the wage month of February 2026. March being the financial year-end, it is also important to reconcile employee PF and ESI records for the entire year and ensure all UANs are activated with updated KYC details.
