November 2026 tax crush puts GST, payroll and company filings on the same clock

Businesses face a tightly packed November 2026 schedule, with GST, TDS, payroll, income tax and corporate filing deadlines converging alongside the transition to new tax forms.

Businesses facing November 2026 compliance should prepare for a dense cluster of tax, payroll and filing deadlines, with obligations spanning GST, income tax, TDS and TCS, corporate filings, and employee contribution payments. Ebizfiling’s compliance calendar says the month includes both routine monthly filings and year-specific cut-offs tied to FY 2025-26 and AY 2026-27, making it especially important for companies, LLPs, OPCs and employers to confirm which rules apply to their own transactions and entity type.

The first major pressure point falls in the opening week of the month. According to the calendars published by Vidhisar, Lexvio, TaxPower and K C Shah, TDS and TCS deposits for October 2026 are due on 7 November, while monthly GST reporting begins shortly after, with GSTR-1 due on 11 November. QRMP taxpayers can use the Invoice Furnishing Facility by 13 November if they choose to report B2B invoices for the first month of the quarter, and several other GST forms, including GSTR-5 and GSTR-6, also fall on that date. Ebizfiling’s schedule adds that GSTR-7 and GSTR-8 for October collections are due on 10 November.

Mid-month is equally crowded. According to Ebizfiling, Form 137, the new book-adjustment statement for government accounts officers, and the quarterly non-salary TDS certificate in Form 131 are due on 15 November. The same date also applies to EPF contributions and ESI payments for October 2026, reflecting the normal monthly payroll cycle. Other GST obligations land on 20 November, when monthly GSTR-3B returns and GSTR-5A for specified non-resident online service providers are due. Several of the independent calendars identify this stretch as one of the busiest compliance windows of the month, particularly for businesses juggling payroll, indirect tax and income tax reporting at the same time.

Later in the month, attention turns to income tax and company-law filings. Ebizfiling says companies and other assessees whose accounts are subject to audit, but are not covered by transfer pricing reporting under section 92E, have an extended return-filing deadline of 21 November for AY 2026-27. The same date applies to LLPs and OPCs in the relevant non-transfer-pricing category. For companies and OPCs, 29 November is also significant: Ebizfiling lists the annual return deadline in MGT-7 or MGT-7A, as well as the PAS-6 reconciliation report for entities covered by dematerialisation rules, as due on that date when the statutory 60-day clock is counted from the relevant 30 September reference point. Companies, LLPs and OPCs that fall within transfer pricing provisions then face a 30 November filing deadline.

The end of the month also brings several year-end GST adjustments. Ebizfiling notes that 30 November is the final date to correct errors or omissions in GSTR-1 for FY 2025-26, report eligible credit notes for that year, and claim eligible input tax credit for FY 2025-26, subject to the earlier of the statutory cut-off or the date of filing the relevant annual return. The calendar also flags reversals under Rule 37A where a supplier has not furnished the corresponding GSTR-3B within the prescribed period. For businesses with complex supply chains, these year-end GST deadlines can be as important as the monthly return dates.

Ebizfiling’s article also reflects a broader shift in the compliance framework for the new income tax regime, which has renamed or consolidated several TDS and TCS forms for transactions governed by the Income-tax Act, 2025 and the Income-tax Rules, 2026. It says older forms may still apply to transactions arising on or before 31 March 2026, while newer forms apply to later periods. That distinction matters because November 2026 includes obligations that straddle the transition between the old and new systems, creating scope for confusion unless taxpayers check the applicable law carefully. Across all the calendars, the consistent message is the same: planning ahead is essential, because a single missed deadline can trigger interest, late fees or other penalties.
