“The books for the March quarter are finally closed, but the pressure isn’t off,” says a seasoned Chartered Accountant to his High-Net-Worth (HNW) client over a late-evening espresso. “In fact, for us, May is when the real legal heavy lifting begins. We aren’t just looking at the new fiscal year; we are reconciling the ghosts of the last one while navigating a 24-hour update cycle that demands absolute precision.”
For tax practitioners and legal consultants, May 2026 is a high-stakes bridge. It requires a perfect balance between the closing requirements of Financial Year (FY) 2025–26 and the new compliance mandates of FY 2026–27. With the Income Tax Act, 2025 now in its first full month of operational effect, the margin for errors in reporting and deposit is razor-thin.
The “May Bridge”: Reconciling the Old and the New
The primary challenge this month is the “dual-compliance” burden. Practitioners are simultaneously filing the final quarterly returns for the preceding year under the Income-tax Act, 1961, while depositing taxes and adhering to new reporting thresholds under the Income Tax Act, 2025.
A critical nuance for May 2026 is the governance of TDS. According to the latest CBDT clarifications, the governing Act is determined by the “earlier of credit or payment.” For transactions credited in March 2026 but paid in April/May, the 1961 Act still applies. However, for all fresh contracts and deductions originating in April 2026, the Income Tax Act, 2025, and its consolidated Section 393 take center stage. This necessitates a bifurcation of data in the accounting software before the filing season peaks.
Direct Tax & TDS: The Q4 Finale
May is synonymous with the Q4 TDS/TCS return filing. This is the final opportunity to ensure that all tax deducted during the Jan–Mar 2026 period is accurately reflected in the payees’ Form 168 (formerly 26AS).
Key Due Dates:
- 07 May 2026: Due date for deposit of TDS/TCS deducted/collected during April 2026. This is the first deposit under the new Act—practitioners must ensure the correct section codes are quoted to avoid portal mismatches.
- 15 May 2026: Filing of Form 27EQ (TCS Return) for the quarter ending March 31, 2026.
- 30 May 2026: Issuance of TCS Certificates for the quarter ending March 31, 2026.
- 31 May 2026: Quarterly TDS Return Filing (Form 24Q, 26Q, 27Q) for Q4 of FY 2025–26. This is a non-negotiable deadline; failure to file can attract fees under Section 234E.
- 31 May 2026: Submission of SFT (Statement of Financial Transactions) in Form 61A for FY 2025–26. With the Income Tax Rules 2026 raising the threshold for certain transactions (e.g., immovable property SFT limits rising to ₹45 Lakh), reporting accuracy is paramount to avoid scrutiny.
Indirect Tax: GSTN’s New Operational Reality
The GST ecosystem in 2026 has transitioned toward automated “Tax Liability Breakups” and real-time reconciliation via the Invoice Management System (IMS). Practitioners must now monitor the IMS daily to accept, reject, or keep invoices pending to optimize Input Tax Credit (ITC).
Key GST Deadlines:
- 10 May 2026: Filing of GSTR-7 (TDS) and GSTR-8 (TCS by e-commerce operators) for April 2026.
- 11 May 2026: Filing of GSTR-1 (Outward Supplies) for monthly filers. Ensure all B2B and B2C data is scrubbed against the newly introduced Table 12A requirements.
- 13 May 2026: Filing of GSTR-6 (ISD) and the optional IFF for QRMP taxpayers.
- 20 May 2026: Filing of GSTR-3B for April 2026 (Monthly filers). Note that the GST portal now auto-populates interest on delayed payments from previous periods—verification is essential before final submission.
Corporate Law: ROC & LLP Compliances
MCA has been active with the CCFS 2026 (Company Compliance Fresh Start) Scheme. While the scheme provides a window for old defaults, the annual cycles continue unabated.
Essential MCA Filings:
- 30 May 2026: Form 11 (LLP Annual Return) for FY 2025–26. Unlike previous years, the MCA portal load is expected to be high due to the concurrent CCFS window. Early filing is advised to avoid the ₹100/day penalty which has no upper ceiling.
- 30 May 2026: PAS-6 (Reconciliation of Share Capital Audit Report) for unlisted public companies for the half-year ended March 31, 2026.
The Practitioner’s Dilemma:
For a modern CA or Tax Lawyer, the challenge isn’t just the dates—it’s the interpretation. A notification issued by the CBIC at 10:00 PM can change the filing logic for a return due the next morning. Manual research through physical volumes or static PDFs is no longer sustainable for a practice aiming at “zero-defect” compliance.
